ASCO Guidelines

Dr. Nabil Saba shares the first evidence-based guideline on thyroid cancer from ASCO. He highlights recommendations on first- and subsequent-line systemic treatment – including multikinase inhibitors (MKIs), genomically targeted therapies, immunotherapy, and cytotoxic chemotherapy across four subtypes of thyroid cancer: well-differentiated, differentiated high-grade or poorly differentiated, anaplastic, and medullary thyroid cancer. He dives into the evidence supporting each recommendation and explains the importance of shared decision-making on the risks and benefits of each treatment option. Dr. Saba also touches on outstanding questions including sequencing of agents, addressing resistance, emerging biomarker targets, and management of toxicities.

Brittany Harvey: Hello and welcome to the ASCO Guidelines podcast, one of ASCO's podcasts delivering timely information to keep you up to date on the latest changes, challenges, and advances in oncology. You can find all the shows, including this one, at asco.org/podcasts. My name is Brittany Harvey, and today I'm interviewing Dr. Nabil Saba from Emory University, lead author on "Systemic Treatment of Thyroid Cancer: ASCO Guideline." Thank you for being here today, Dr. Saba. Dr. Nabil Saba: Pleasure to be here. Brittany Harvey: And then just before we discuss this guideline, I'd like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO conflict of interest policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Saba, who has joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes. So then to dive into what we're here today to talk about, Dr. Saba, could you start us off by providing a general overview of the scope and purpose of this first ASCO guideline for thyroid cancer? Dr. Nabil Saba: So thyroid cancer is a complex disease, and the complexity has been added with the advent of multiple systemic therapeutic agents that have recently come on as part of the standard of care for treating this disease. The guidelines have lagged behind, I believe, in terms of being able to clearly delineate how to use these agents and what clinical settings to use them. And so this guideline, I think, is a much-needed and much-awaited guideline for clinicians to allow them to understand better the use of systemic agents in the treatment of thyroid cancer. And when we talk about systemic agents, what we want to specify is this applies mostly for patients with recurrent metastatic disease, patients who have failed the standard initial treatment, which continues to be surgical resection for these patients if surgery is possible, in addition to radioiodine therapy for the right clinical setting. Brittany Harvey: Absolutely. It's a good point that this patient population for this guideline focuses mainly on recurrent disease and patients who have already received surgery and radioactive iodine therapy. So then this guideline covers four subtypes of thyroid cancer, including well-differentiated, differentiated high-grade or poorly differentiated, anaplastic, and medullary thyroid cancer. As you mentioned, you address clinical questions on systemic therapies, including multikinase inhibitors, genomically targeted therapies, immunotherapy, and cytotoxic chemotherapy in both the first-line and subsequent lines for each of these subtypes. So I'd like to review the key recommendations by subtype. So first, what are the key points for systemic therapy for well-differentiated thyroid cancer? Dr. Nabil Saba: It's important to also stress the point that we have these different subtypes of thyroid cancer. So when we talk about radioiodine refractory, those are for patients who are candidates for radioiodine therapy, of course. This usually encompasses the well-differentiated thyroid cancer. So for this group of patients, the guideline focuses on whether the use of multikinase inhibitors compared to placebo or observation impacts the survival in the first-line setting, whether the use of targeted therapies compared to placebo impacts also the survival in the first-line setting, all in the radioiodine refractory setting, of course. And then we tackle the issue of immunotherapy because this also is a topic that has entered the realm, if you like, of thyroid cancer and is being used in some subtypes of thyroid cancer. So we thought it would be important to raise the question of the role of immunotherapy compared to targeted agents or mult

Dr. Timothy Gilligan and Dr. Calvin Chou discuss the updated guideline on patient-clinician communication in oncology. They highlight clinical recommendations and strategies on topics such as communication skills and practices that apply at every visit, principles for telehealth interactions, cross-disciplinary communication, facilitating involvement of the patient's support network, discussing prognosis, goals of care, treatment selection – including clinical trials, end-of-life discussions, overcoming barriers to communication, facilitating discussions of cost of care and financial toxicity, mitigating stigma, and setting boundaries with patients. Dr. Gilligan and Dr. Chou also share how clinicians can enhance their communication skills through skills practice opportunities and experiential learning. They discuss how fundamental communication is to optimal patient care and look to the future on how generative AI may impact healthcare communication.

You can find all the shows, including this one, at asco.org/podcasts. My name is Brittany Harvey, and today I am interviewing Dr. Timothy Gilligan from Taussig Cancer Institute and the Center for Excellence in Healthcare Communication at Cleveland Clinic, and Dr. Calvin Chou from the University of California and Veterans Affairs Health Care System in San Francisco, co-chairs on "Patient-Clinician Communication: ASCO Guideline Update." Thank you for being here today, Dr. Gilligan and Dr. Chou. Dr. Timothy Gilligan: Thank you for having us. Dr. Calvin Chou: Delighted to be here. Brittany Harvey: And then just before we discuss this guideline, I would like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO Conflict of Interest Policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Gilligan and Dr. Chou who have joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes. So then I would like to dive into what we are here really today to talk about. So Dr. Gilligan, this guideline updates the patient-clinician communication guideline that was first published in 2017. What prompted this update and what is the scope of this updated guideline? Dr. Timothy Gilligan: So I think with the first guideline, that was the first draft of it that we published five or six, seven years ago, really we were focused on getting the content right, what was the state of the knowledge at that time, and I was very happy with what came out of that. But when I looked back on it, I thought there were ways we could make it more accessible and more practical. Because what we really would like would be for people to apply what we know and then communicate more effectively with patients and colleagues. And one of the reasons I was really excited on the membership of the panel we had this time was I thought they were very well selected to help us do that, is to really think about what are practical guidelines, practical steps we can tell people to take that will improve their own experience and the experience of patients and the quality of care. Brittany Harvey: Absolutely, thinking about operationalizing that guideline really improves the dissemination and the uptake of these recommendations. So then, Dr. Chou, I would like to review the key recommendations and strategies across the clinical questions that the guideline addressed. I realize today with our limited time we may not be able to go through every recommendation and strategy, so we will start with some of the highlights. First, let's address the highlights of the process of communication with patients and their support networks. This includes the questions that address what communication skills and practices apply at every visit across the continuum of care, principles for telehealth interactions, cross-disciplinary communication, and facilitating involvement of the patient's support network. In your view, what are the most important recommendations across these clinical questions? Dr. Calvin Chou: I think the thing that all clinicians know in their bones that they want to be able to do effectively with patients is to communicate information clearly, as well as to communicate in a way that really deepens the relationship, demonstrates empathy, and als

Dr. Lakshmi Rajdev and Dr. Manish Shah join the podcast to discuss the updated guideline on immunotherapy and targeted therapy in unresectable locally advanced, advanced, or metastatic gastroesophageal cancer. They share first-line and subsequent-line recommendations for both gastroesophageal adenocarcinoma and esophageal squamous cell carcinoma based on actionable biomarkers including PD-L1 expression, MMR and/or MSI, CLDN18.2 expression, and HER2 status. They note the importance of the algorithms and tables in the guidelines that provide visual illustrations and quick reference guides of the evidence-based recommendations. They also comment on ongoing and recently presented trials that may impact future guidelines in this space.

My name is Brittany Harvey, and today I am interviewing Dr. Lakshmi Rajdev from the Icahn School of Medicine at Mount Sinai and Dr. Manish Shah from Weill Cornell Medicine, co-chairs on "Immunotherapy and Targeted Therapy for Advanced Gastroesophageal Cancer: ASCO Guideline Update." Thank you for being here today, Dr. Rajdev and Dr. Shah. Dr. Lakshmi Rajdev: Thank you. Dr. Manish Shah: Thank you for having us. It is wonderful. Brittany Harvey: And then just before we discuss this guideline, I would like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO conflict of interest policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Rajdev and Dr. Shah, who have joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes. So then to dive into what we are here today to talk about, Dr. Shah, I would like to start first with what prompted the update to this guideline, which was previously published in 2023, and what is the scope of this updated guideline? Dr. Manish Shah: Yes, terrific. So even in the last few years, the pace of drug development in gastroesophageal cancers has just been astounding. So, what prompted this guideline is actually the practice-changing results for a new biomarker, CLDN18.2 hat was based on the GLOW and SPOTLIGHT studies, as well as a practice-changing study in HER2-positive disease where we added pembrolizumab to trastuzumab and chemotherapy for tumors that are HER2-positive and PD-L1 CPS 1 or greater. And then there were also new studies and new approvals in esophageal squamous cell cancer that you will hear about as well. So there were several studies, overall more than 5,000 patients were reported on, and that led to several new therapies, new indications, and it really necessitated this guideline. Brittany Harvey: Excellent. It is great to hear about all of these exciting updates in this space. So then to next review the key recommendations of this guideline by clinical question that the expert panel addressed. So, Dr. Rajdev, what is the recommended first-line treatment for patients with proficient mismatch repair, microsatellite stable, HER2-negative gastroesophageal adenocarcinoma? Dr. Lakshmi Rajdev: Thank you for that question. So historically, we have sort of used fluoropyrimidine and platinum doublets, which yielded a survival of about one year. More recently, immunotherapy and targeted therapy options have improved outcomes in patients with advanced esophageal and gastric adenocarcinoma, as well as squamous cell carcinoma. Patients with gastric and GE junction adenocarcinoma have a high rate of actionable alterations, so it is imperative that physicians test the following biomarkers upfront so that i

Dr. Bishal Gyawali and Dr. Tessa Cigler share the new, comprehensive, evidence-based update of the ASCO guideline on the use of hematopoietic colony-stimulating factors in patients with cancer. They discuss recommendations on primary prophylaxis, secondary prophylaxis, and treatment of febrile neutropenia along with stem cell mobilization, efficacy, safety, duration, dosing, and administration of CSFs – including biosimilars. They highlight where it is appropriate to use a CSF, and importantly, when not to use a CSF. They touch on the significance of individual patient considerations and cost implications, and future work to refine the risk factors for the development of complications of febrile neutropenia.

You can find all the shows, including this one, at asco.org/podcasts. My name is Brittany Harvey, and today I'm interviewing Dr. Bishal Gyawali from Queen's University in Kingston, Ontario, Canada, and Dr. Tessa Cigler from Weill Cornell Medicine in New York, New York, co-chairs on "White Blood Cell Growth Factors: ASCO Guideline Update." Thank you for being here today, Dr. Gyawali and Dr. Cigler. Dr. Bishal Gyawali: Thank you very much for having me. It's a pleasure. Dr. Tessa Cigler: Hi there. Nice to be here as well. Brittany Harvey: Great. And then before we discuss this guideline, I'd like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO Conflict of Interest Policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Cigler and Dr. Gyawali, who have joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes. So then I'd like to dive into the guideline that we're here today to talk about. So first, what prompted an update to this guideline on the use of hematopoietic colony-stimulating factors in patients with cancer, and what is the scope of this updated guideline? Dr. Bishal Gyawali: The last version of the guidelines from ASCO on this topic was back in 2015, so it has been more than a decade since ASCO had a guideline on the use of G-CSF in patients with cancer receiving treatment. So it was due for an update because there has been a lot more evidence based on not necessarily new drugs, but evidence for proper timing of these agents and the duration of these agents, as well as there have been a lot of new biosimilars, and there are questions about are these biosimilars equivalent or how do we choose among these different options. One is that content of the evidence that has evolved over time in the last decade, but also I think the last time we had these guidelines, the ASCO guidelines were not incorporated to have those evidence GRADE tables. So the quality of the ASCO guidelines itself has evolved over the years, so we wanted to have a new version of the guideline that includes not only the new evidence, but also contains those evidence GRADE tables that will help to quantify the benefits. And so I think it was high time, and even more than that, the newer ASCO guidelines for any guideline, they also include considerations of cost, access, equity, and all these factors that were not included in the previous version of the guideline. So I think it's only natural that with time the guideline should also evolve. Dr. Tessa Cigler: I agree completely, and just as a framework, as we all know, neutropenia and its complications, including febrile neutropenia and infections, are still an important toxicity of many myelosuppressive chemotherapies. And these neutropenic complications do require prompt evaluation and treatment and often hospitalization, and we know that hematopoietic colony-stimulating factors, which I'm going to refer to as growth factors, can reduce the duration and severity of neutropenia and the risk of febrile neutropenia, so it remains an important topic in the practice of clinical oncology. Brittany Harvey: Absolutely. It's an important topic for both clinicians and for patients who are receiving treatment for their cancer. And as you said, there was a substantial amount of literature to review here and updating everything to be in line with the GRADE evidence rating system, so there was a lot of work that you both put into this. So then next, I'd like to re

You can find all the shows, including this one, at asco.org/podcasts. My name is Brittany Harvey, and today I'm interviewing Dr. Sonam Puri from Moffitt Cancer Center, co-chair on "Therapy for Stage IV Non-Small Cell Lung Cancer with Driver Alterations: ASCO Living Guideline, Version 2026.3.0." It's great to have you here today, Dr. Puri. Dr. Sonam Puri: Thanks, Brittany. Brittany Harvey: And then just before we discuss this guideline, I'd like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO Conflict of Interest Policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Puri, who has joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes. So then, to dive into the content that we're here today to talk about, Dr. Puri, this living clinical practice guideline for systemic therapy for patients with stage IV non-small cell lung cancer with driver alterations is updated on an ongoing basis. So, what data prompted this latest update to the recommendations? Dr. Sonam Puri: So Brittany, non-small cell lung cancer is one of the fastest-moving areas in oncology right now, particularly when it comes to targeted therapy for driver alterations. New data are emerging continuously from clinical trials, regulatory approvals, real-world experience, which is exactly why these are living guidelines. The goal is to rapidly integrate important advances as they happen, rather than waiting for years for a traditional update. Since the last full update of the ASCO Stage IV Non-small Cell Lung Cancer Guideline with Driver Alterations published in 2024, there have been seven new regulatory approvals and changes in first-line therapy for some driver alterations. [This version] of the "Stage IV Non-small Cell Lung Cancer Guidelines with Driver Alterations" represents a full update, which means that the panel reviewed and refreshed every applicable section of the guideline to reflect the most current evidence across therapies including sequencing and clinical decision-making. This is to ensure that clinicians have up-to-date practical guidelines that keep pace with how quickly the field is evolving. Brittany Harvey: Absolutely. As you mentioned, this is a very fast-moving space and this full update helps condense all of those versions that the panel reviewed before into one document, along with additional approvals and new trials that you reviewed during this time period. So then, the first aspect of the guideline is there's a new overarching recommendation on biomarker testing. Could you speak a little bit to that updated recommendation? Dr. Sonam Puri: Yeah, definitely. So the panel has discussed and provided recommendations on comprehensive biomarker testing and its importance in all patients diagnosed with non-small cell lung cancer. Ideally, biomarker testing should include a broad-based next-generation sequencing panel, rather than single-gene tests, along with immunohistochemistry for important markers such as PD-L1, HER2, and MET. These results really drive treatment decisions, both in frontline settings for all patients diagnosed with non-small cell lung cancer and in subsequent line settings for patients with non-small cell lung cancer harboring certain targetable alterations. Specifically in the frontline setting, it helps determine whether a patient should receive upfront targeted therapy or immunotherapy-based approach. We now have strong data that shows that complete molecular profiling results before starting first-line therapy is associated with better overall survival and actually more cost-effective care. Using both tissue and bl

Dr. Joshua Reuss is back on the podcast to discuss the full update to the living guideline on stage IV NSCLC without driver alterations. He discusses the new evidence and how this impacts the latest recommendations on first-line and subsequent therapeutic options. Dr. Reuss emphasizes the need for shared decision-making between clinicians and patients. He shares ongoing research that the panel will review in the future for further updates to this living guideline, and puts the updated recommendations into context for clinicians treating patients with stage IV NSCLC.

My name is Brittany Harvey, and today I am interviewing Dr. Joshua Reuss from Georgetown University, co-chair on "Therapy for Stage IV Non-Small Cell Lung Cancer Without Driver Alterations: ASCO Living Guideline, Version 2026.3.0." It is great to have you back on the show today, Dr. Reuss. Dr. Joshua Reuss: Happy to be here, Brittany. Brittany Harvey: Just before we discuss this guideline, I would like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO Conflict of Interest Policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Reuss who has joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes. Dr. Reuss, this living clinical practice guideline for systemic therapy for patients with stage IV non-small cell lung cancer without driver alterations is updated on an ongoing basis. So, what prompted this latest update to the recommendations? Dr. Joshua Reuss: Our committee is tasked with making routine updates to the living guidelines and really keeping them living, right? So, evaluating new data as it is coming in to see, is this practice changing? Is this data that should inform and potentially alter our guideline recommendations so that practitioners and other care providers could really make the best treatment decisions for their patients? So that is something that happens on a more routine basis, but periodically, we are tasked with performing a more comprehensive update of our guideline where we really evaluate every one of our point recommendations, the data associated with these recommendations, to be sure that these are up to date, these are comprehensive, and to see if we need to alter anything in the language of these updates. Brittany Harvey: Excellent. Thank you for providing that background. And yes, this is truly a comprehensive update that goes through all the latest literature. Given that, I would like to review what has changed and what is new in the recommendations. So, what are the updated recommendations on first-line therapy for patients with stage IV non-small cell lung cancer without driver alterations? Dr. Joshua Reuss: So there are two main guidelines that we recommend from this panel. One is a driver mutation-positive guideline and the other is a driver mutation-negative guideline. And I think on first blush, one might look at kind of the recent flurry of approvals and new data and say, well, all the excitement, you know, is in the driver mutation-positive guideline. But I would say that the driver mutation-negative guideline is equally as important and really has several unique challenges associated with it. You know, first and foremost is that there are really a multitude of regimens that can be considered for any one patient. And how to choose between one can be quite difficult and a stressful challenge that clinicians can have, particularly since there are really no randomized studies comparing these regimens in a head-to-head fashion. In addition, you know, these guidelines are really broken down by two key factors. One is disease histology, so namely squamous versus non-squamous histology. And the other is PD-L1 status, broken down into one of three tertiles: PD-L1 high, which is greater than or equal to 50% expression; PD-L1 low, which is 1% to 49% expression; and then PD-L1 negative or unknown. So what you are really looking at, if you do that math, is really six unique patient subpopulations where we need to make a recommendation on one of t

My name is Brittany Harvey, and today I am interviewing Dr. Mary-Ellen Taplin from Dana-Farber Cancer Institute, lead author on "Systemic Therapy in Patients With Metastatic Castration-Resistant Prostate Cancer: ASCO Living Guideline, Version 2026.1." Thank you for being here today, Dr. Taplin. Dr. Mary-Ellen Taplin: Thank you, Brittany. It is a pleasure. Brittany Harvey: Before we discuss this guideline, I would like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO Conflict of Interest Policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Taplin who has joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes. To dive into the content here and what we are here today to talk about, this living clinical practice guideline for systemic therapy for patients with metastatic castration-resistant prostate cancer is updated on an ongoing basis. Dr. Taplin, what prompted this latest update to the recommendations? Dr. Mary-Ellen Taplin: Thank you, Brittany. Several things prompted the latest update. There have been several phase III trials that have been practice-changing that have resulted in the last several years that needed to be added to the guidelines to inform clinicians of comprehensive treatment options. Brittany Harvey: Great, and it is great to have this updated guideline for readers. I would like to review the changes to the recommendations in this latest iteration across the patient populations that are outlined in the guideline. So, starting with: What are the updated recommendations for patients previously treated with androgen deprivation therapy alone whose disease has progressed to metastatic castration-resistant prostate cancer? Dr. Mary-Ellen Taplin: A nice feature of this guideline is that in addition to the tables, which provide detailed options, is at the end of the guidelines, our readers will find very clear algorithms that describe past treatment scenarios that patients could have had and then outline their treatment options. So it is very clear. Our clinicians will love these algorithms. And one of the changes for the disease state that you mentioned, which is the least treated castration-resistant state of prostate cancer which is previously treated with ADT alone, is that we recommend testing for mutations in the HRR, homologous recombination repair, genes. And the ones that are specifically known and applicable to prostate cancer are the BRCA genes. So there is clear recommendation of testing to remind us, as treating physicians, that now is the time, if it hasn't been done before, to institute both germline and somatic testing. And somatic testing, if it can be done on tissue, is preferable, but if not, the liquid biopsy approaches, the ctDNA approaches, have now advanced to the point that most patients with metastatic prostate cancer will be able to successfully have testing on the liquid biopsies. So that is number one, testing. And then the new treatment options include, if a patient does have an HRR gene alteration, and maybe about 20-25 percent of patients will be in that category, the combinations of an androgen pathway inhibitor and a PARP inhibitor are now treatment options. So for instance, talazoparib and enzalutamide; olaparib and abiraterone; or niraparib and abiraterone are some of the newer treatment options if the patient is HRR-positive. So, Brittany, in regard to patients treated with ADT alone, another new treatment option is th

So what prompted this update and what is the scope of this updated guideline? Dr. Joseph Mikhael: It is amazing when we think back in myeloma years, 2019 actually seems a very, very long time ago because really so much has changed in myeloma over these last six to seven years. Indeed, there have been over 150 randomized controlled trials that we didn't have at the prior guideline that we reviewed for this. Myeloma is a disease that has really changed so dramatically over these last several years. Multiple new agents have been introduced. We now have CAR-T cell therapy, bispecific antibodies, and multiple other agents that were not available at the time. Furthermore, with this growing complexity, it is becoming more important than ever to be able to provide practical advice and guidelines to the oncology community. For most oncologists, they have less than 5% of their time dedicated to multiple myeloma. It is important to bring a clarity to them that allows them to care for their patients. And the scope of these guidelines, furthermore, really cover the whole spectrum of myeloma. They go further than our prior guideline where now we have included smoldering multiple myeloma along with frontline therapy and relapsed multiple myeloma. So, we have really tried to provide the full spectrum to our colleagues in oncology to ensure that they have the tools they need to provide the best care possible for their patients. Dr. Lisa Hicks: That is a really terrific summary. And maybe one thing I will just add is it is really unique to have this much literature. I can't think of another guideline that I have ever been involved with that has seen a field move so quickly and develop so many advancements in a period of just over four or five years. Brittany Harvey: Certainly, there is a large volume of evidence that you all had to review for this guideline update. I think to your point probably one of the greater volumes of literature for a guideline update that you both mentioned. Based on that, I would like to review the key recommendations that are updated in this guideline. So Dr. Hicks, that new patient population that Dr. Mikhael mentioned earlier, what are the key recommendations for patients with smoldering multiple myeloma? Dr. Lisa Hicks: So this is the first time that an ASCO guideline is addressing this branch of multiple myelo

Dr. Alison Loren and Dr. Ann Partridge share the latest guideline from ASCO on the management of cancer during pregnancy. They highlight the importance of this multidisciplinary, evidence-based guideline and overarching principles for the management of cancer during pregnancy. Drs. Loren and Partridge discuss key recommendations from each section of the guideline, including diagnostic evaluation, oncologic management, obstetrical management, and psychological and social support. They also touch on the importance of this guideline and accompanying tools for clinicians and how this serves as a framework for pregnant patients with cancer. The conversation wraps up with a discussion on the unanswered questions and how future evidence will inform guideline updates.

You can find all the shows, including this one, at asco.org/podcasts. My name is Brittany Harvey, and today I am interviewing Dr. Alison Loren from the Perelman School of Medicine of the University of Pennsylvania and Dr. Ann Partridge from Dana-Farber Cancer Institute, co-chairs on "Management of Cancer During Pregnancy: ASCO Guideline." Thank you for being here today, Dr. Loren and Dr. Partridge. Dr. Alison Loren: Thanks for having us. Dr. Ann Partridge: It's a pleasure. Brittany Harvey: And then just before we discuss this guideline, I would like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO conflict of interest policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Partridge and Dr. Loren who have joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes. So then to dive into the meat of this guideline, to start us off, Dr. Loren, could you provide an overview of the scope and purpose of this new guideline on the optimal management of cancer during pregnancy? Dr. Alison Loren: Sure, thanks, Brittany. So this was really born out of I think a lot of passion and concern for this really vulnerable patient population. We have observed, and I am sure it is not any surprise to your audience, that the incidence of cancer in young people is increasing. And simultaneously, people are choosing to become pregnant at older ages, and so we are seeing more and more people with a cancer diagnosis during their pregnancy. And for probably obvious reasons, there is really no way to do randomized clinical trials in this population. And so really trying to assemble and articulate the best evidence for safely managing the diagnosis of cancer, the management of cancer once it is confirmed, being thoughtful about obviously the health of the mom, but also attending to potential risks to the developing fetus, and really just trying to be really comprehensive and balanced about all the choices for these patients when they are facing some really challenging decisions in a very emotionally fraught environment. And I think it is really emotionally fraught for the providers, too. You know, this is obviously an extremely intense, very emotional set of decisions, and so trying to provide a rudder essentially to sort of help people frame the questions and trying to make as evidence-based a set of recommendations as possible. Dr. Ann Partridge: And I would just add that "evidence-based" is a strong word here because typically our, as you just heard, our gold standard evidence is a randomized trial, but you can't do that in this setting, in general. And so, what we were able to do with the support of the phenomenal ASCO staff was to pull together kind of the world's literature on the safety and outcomes of treatments during pregnancy, as well as consensus opinion. And I think that is a really, really critical difference about this particular guideline compared to many of the other ones that ASCO does, where consensus and good judgment needed to kind of rule the day when evidence is not available. So, there is a lot of that in our recommendations. Dr. Alison Loren: That is such a good point. And I just, before we move forward, I just want to reflect that the composition of the panel was really broad and wide-ranging. We had maternal medicine specialists, we had legal and ethical experts, we had representatives who understand pharmaceutical industries' pers

Dr. Tanya Thomas and Dr. Aparna Jotwani join the podcast to discuss the new Oncology Nursing Society and American Society of Clinical Oncology evidence-based guideline on the management of antineoplastic extravasation. They discuss recommendations from the expert panel on: management of extravasation of vesicant or irritant with vesicant properties antineoplastic agents, management of extravasation of paclitaxel or docetaxel, use & duration of thermal compress, and escalation of care. They share the importance of this comprehensive interdisciplinary guideline, highlight the algorithm as a useful tool for clinicians, and outline the outstanding questions related to the management of extravasation.

My name is Brittany Harvey, and today I'm interviewing Dr. Tanya Thomas, clinical chair of the guideline and clinical nurse specialist from University of Virginia Health, and Dr. Aparna Jotwani, medical oncologist from Baylor College of Medicine, authors on "Management of Antineoplastic Extravasation: Oncology Nursing Society – American Society of Clinical Oncology Guideline." Thank you for being here today, Dr. Thomas and Dr. Jotwani. Dr. Aparna Jotwani: Thank you. Dr. Tanya Thomas: Thank you for having us. Brittany Harvey: And then before we discuss this guideline, I'd like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO conflict of interest policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Thomas and Dr. Jotwani, who have joined us here today, are available online with the publication of the guideline in JCO Oncology Practice, which is linked in the show notes. So then to dive into the content here, Dr. Thomas, could you start us off by providing an overview of both the scope and the objectives of this guideline? Dr. Tanya Thomas: Yes, so the objective of this guideline is to provide the evidence-based recommendations to help support our interdisciplinary teams, including the oncologist, the advanced practice providers, pharmacists, and nurses who are involved in the care and management of patients who are experiencing an extravasation of an antineoplastic agent. While rare, the antineoplastic and certain chemotherapy extravasations are oncologic emergencies. The recommendations are to minimize negative consequences and provide a standardized approach to the care when such an event occurs. Dr. Aparna Jotwani: I would add that our scope is limited to intravenous antineoplastic vesicants, irritants, and irritants with vesicant potential. The scope of the guideline applies to the care team for adult oncology patients receiving treatments through venous access. Outside the scope is management of extravasation during other routes of treatment administration, such as intraperitoneal, intravesical, and hepatic arterial infusion. Our recommendations regarding vascular access for therapy or interventions to prevent extravasations are also outside of the scope for this guideline. Brittany Harvey: Understood. I appreciate that background and understanding what's in scope and what's out of scope for this guideline. So then I'd like to pivot and talk about the key recommendations of this guideline across the clinical questions. So first, Dr. Jotwani, what does the panel recommend for patients with extravasation of vesicant or irritant with vesicant properties antineoplastic agents? Dr. Aparna Jotwani: The panel strongly recommends for all classes where an antidote exists to proceed with using the antidote. Recommendations for paclitaxel and docetaxel are specifically addressed in a recommendation. This is further detailed in Tables 1 and 4 within the guideline. Evidence on the use of antidotes for extravasation is limited to nonrandomized, uncontrolled, observational studies and case series. Placebo-controlled trials on this topic would be unethical. There is also a lack of comparative data for different antidote strategies. However, potential benefits of using the antidotes include tissue preservation and avoiding tissue necrosis. In developing the guidelines, we had an in-person roundtable discussion and weighed risks and benefits to ensure patient safety above all else. Brittany Harvey: I appreciate th

Dr. Kathleen Horst, Dr. Rachel Jimenez, and Dr. Yara Abdou discuss the updated guideline from ASTRO, ASCO, and SSO on postmastectomy radiation therapy.

My name is Brittany Harvey, and today I am interviewing Dr. Kathleen Horst, expert panel chair from Stanford University; Dr. Rachel Jimenez, expert panel vice chair from Massachusetts General Hospital; and Dr. Yara Abdou, ASCO representative from the University of North Carolina, authors on "Postmastectomy Radiation Therapy: An American Society for Radiation Oncology, American Society of Clinical Oncology, and Society of Surgical Oncology Clinical Practice Guideline." Thank you for being here today, Dr. Horst, Dr. Jimenez, and Dr. Abdou. Dr. Kathleen Horst: Thank you for having us. Brittany Harvey: And then just before we discuss this guideline, I would like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO conflict of interest policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Horst, Dr. Jimenez, and Dr. Abdou who have joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes. Then to dive into the content that we are here today to talk about, Dr. Horst, could you start us off by describing what prompted the update for this joint guideline between ASTRO, ASCO, and SSO, and what is the scope of this 2025 guideline on postmastectomy radiation therapy? Dr. Kathleen Horst: Thank you. This joint guideline was last updated in 2016. Over the past decade, the treatment of breast cancer has evolved substantially. Newer systemic therapy regimens have increasingly personalized treatment based on tumor biology, and local therapy management has explored both the de-escalation of axillary surgery and more abbreviated courses of radiation therapy. Given these advances, it was important to revisit the role of postmastectomy radiotherapy in this modern era of breast cancer therapy. This updated guideline addresses four key questions, including postmastectomy radiation therapy after upfront surgery as well as after neoadjuvant systemic therapy. It also reviews the evolving role of various dose and fractionation schedules and optimal treatment techniques and dose constraints. Brittany Harvey: Excellent. I appreciate that background, Dr. Horst. So then, next, Dr. Jimenez, I would like to review the recommendations of this guideline across those four key questions that Dr. Horst just mentioned. So first, what does the panel recommend for PMRT for patients who received initial treatment with mastectomy? Dr. Rachel Jimenez: The panel provided pretty strong consensus that patients with positive lymph nodes or patients with large tumors involving the skin or the chest wall should receive postmastectomy radiation. However, the panel also recognized that the omission of postmastectomy radiation may be appropriate for select patients who have positive lymph nodes and have an axillary lymph node dissection if they have a low nodal burden and other favorable clinical or pathologic features. For patients without lymph node involvement at the time of surgery and no involvement of the skin or chest wall, postmastectomy radiation was not advised by the panel. Brittany Harvey: Understood. It is helpful to understand those recommendations for that patient population. Following that, Dr. Abdou, what are the key recommendations for PMRT for patients who received neoadjuvant systemic therapy before mastectomy? Dr. Yara Abdou: When we think about PMRT after neoadjuvant treatment, the key point is that the initial stage of presentation still matters a lot. So for example, if a patient comes in with more advanced disease, say a large primary tumor, l

Dr. Cris Bergerot and Dr. Enrique Soto join the podcast to discuss the new global guideline on geriatric assessment. This guideline provides evidence-based, resource-stratified recommendations across the basic, limited, and enhanced settings. Dr. Bergerot and Dr. Soto discuss who should receive a geriatric assessment, the role of geriatric assessment, which elements of geriatric assessment can help predict adverse outcomes, and how a geriatric assessment is used to guide care and make treatment decisions. They comment on the importance of this guideline worldwide, and the impact of this guideline for a wide range of clinicians, patients, researchers, policymakers, and health administrators.

You can find all the shows, including this one, at asco.org/podcasts. My name is Brittany Harvey, and today I'm interviewing Dr. Cris Bergerot from OncoClínicas & Co and Dr. Enrique Soto from the University of Colorado, co-chairs on "Geriatric Assessment: ASCO Global Guideline". Thank you for being here today, Dr. Bergerot and Dr. Soto. Dr. Cris Bergerot: Thank you. Dr. Enrique Soto: Thanks for the invitation, Brittany. Brittany Harvey: And then before we discuss this guideline, I'd like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO conflict of interest policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Bergerot and Dr. Soto who have joined us here today, are available online with the publication of the guideline in JCO Global Oncology, which is linked in the show notes. So then to jump into the guideline here, Dr. Soto, could you start by providing an overview of the scope and the purpose of this global guideline on geriatric assessment? Dr. Enrique Soto: Of course, Brittany. So, this guideline comes from a request from the global oncology community and from the geriatric oncology community, who is very interested in making sure that geriatric oncology recommendations that are used in the United States can be adopted and used globally. So, this was a very highly rated topic when we had our call for proposals for guidelines, and that's why we decided to do this. The idea of this guideline is to provide resource-stratified recommendations for the use of geriatric assessments and interventions in older adults with cancer across different settings, right? And that these guidelines can be applied by clinicians working in low- and middle-income countries, but also, in a way, by clinicians working in community settings where the availability of resources may be limited. And the idea of these recommendations is to help clinicians evaluate older people with cancer better and also understand which interventions can be implemented with the resources they have and which interventions have a bigger bang for the buck, so to speak. And as all evidence-based, stratified guidelines that ASCO conducts, we stratified resources as basic, limited, or enhanced. And that means resources that go from those that provide the greatest benefits for patients in terms of outcomes to those that are evidence-based but provide additional additive benefits. And those resource-stratified recommendations can be found in the ASCO website as to how these guidelines are developed, and that's pretty standard for most resource-stratified guidelines. Brittany Harvey: Great. I appreciate that background and the impetus for this guideline, and thank you for providing that resource-stratified framework of basic, limited, and enhanced. I think that helps provide context for the guideline recommendations here. So then, Dr. Bergerot, I'd like to next review the key recommendations of this guideline across the four clinical questions that the guideline addresses. So, across those settings, the basic, limited, and enhanced settings, what is the role of geriatric assessment in older adults with cancer to inform specific interventions? Dr. Cris Bergerot: I think this is one of the most important points, so let's break it down. First off, who should actually receive the geriatric assessment? And the recommendation is clear. All patients aged 65 and older who are being considered for systemic cancer therapy should undergo a geriatric assessment. Now, depending on the available resources, for example, in basic setting, a quick

Ms. Kim Woofter and Dr. John Cox discuss the latest updates to the evidence-based standards on oncology medical homes developed by ASCO and COA.

My name is Brittany Harvey, and today I'm interviewing Ms. Kim Woofter, a registered nurse in practice leadership and administration from AC3 Inc in South Bend, Indiana, and Dr. John Cox, a medical oncologist and adjunct faculty member from UT Southwestern Medical Center in Dallas, Texas, co-chairs on "Oncology Medical Homes, American Society of Clinical Oncology – Community Oncology Alliance Standards." Thank you for being here today, Ms. Woofter and Dr. Cox. Dr. John Cox: You bet. Ms. Kim Woofter: Thank you. Brittany Harvey: And then before we discuss these standards, I'd just like to note that ASCO takes great care in the development of its standards and ensuring that the ASCO Conflict of Interest Policy is followed for each guidance product. The disclosures of potential conflicts of interest for the expert panel, including Dr. Cox and Ms. Woofter, who have joined us here today, are available online with the publication of the standards in JCO Oncology Practice, which is linked in the show notes. So then, to dive into what we're here today to talk about, Dr. Cox, could you start us off by explaining what prompted an update to these ASCO-COA standards and what the scope of this update is? Dr. John Cox: Well, the ASCO-COA standards relative to defining and outlining Oncology Medical Home were initially published four or five years ago. At the time, we planned a regular update of the standards. So, in essence, this is a planned update. The whole program is built on the idea of continuous improvement. So, this update and future updates are prompted and defined by our literature, our science, the science of care delivery, and new developments and insights gained from studies and evaluations of care delivery methods, and informed by the practice. These standards are in place to underpin a program of care delivery by ASCO, the ASCO Certified, and as practices engage in this program, we are learning from them. The whole idea is to enlarge and improve how patients are cared for in practice. Brittany Harvey: Absolutely. It's great to have this iterative process to continue to review the evidence and update these standards that form the basis for ASCO Certified. So then, following that background, Ms. Woofter, I'd like to review the key points of the revised standards for our listeners. First, how do the revised standards address the culture of safety and just culture in oncology practice? Ms. Kim Woofter: I think safety is of utmost importance to all of us. So let me say that first and foremost. And what we know in oncology is our QOPI standards already address safety in the infusion suite process. So, safe delivery of chemotherapy agents and antineoplastics. It also talked about near misses and medication errors - absolutely essential, for sure. But what we need to do is look at a more systemic approach to safety because we know is processes throughout an organization they'll often cause you trouble. To do that, we know you need what we call a just culture, which is a very common term in today's workplace. But what it really means is it's a culture of open reporting of any potential for error, any potential for malfunction, and it can be in any place in the organization. So, what we are doing in our new standard is to say, look at your entire processes throughout the organization, and approach that in an open-minded way so that people don't feel scared to report things, and it's a really positive approach to intervening early and making sure that errors don't occur anywhere in the workplace. Brittany Harvey: Taking that systemic approach to look at overarching processes seems really key to ensuring safety in oncology practices. So then, the next new section, Dr. Cox, what are th

You can find all the shows, including this one, at asco.org/podcasts. My name is Brittany Harvey, and today I'm interviewing Dr. Joshua Reuss from Georgetown University, co-chair on "Therapy for Stage IV Non–Small Cell Lung Cancer With Driver Alterations: ASCO Living Guideline, Version 2025.1." It's great to have you here today, Dr. Reuss. Dr. Joshua Reuss: Thank you. Happy to be here. Brittany Harvey: And then before we discuss this guideline, I'd like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO conflict of interest policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Reuss, who has joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes. So to dive into what we're here today to talk about, Dr. Reuss, this living clinical practice guideline for systemic therapy for patients with stage IV non–small cell lung cancer with driver alterations is updated on an ongoing basis. So what prompted this latest update to the recommendations? Dr. Joshua Reuss: Yes, thank you. It's very important that we have living guidelines that are continuously updated. We obviously don't live in a static environment where things are non-changing, and we really need to apply the most up-to-date and current evidence to treat our patients with the most effective strategies, the most groundbreaking strategies. And so to have guidelines that can be disseminated, particularly these ASCO guidelines, to treating providers is incredibly important. So, with any of these updates, we review ongoing studies, published work, for the quality of evidence to see if it's something that warrants making adjustments to our guidelines or at least incorporating the information so that providers can review it and incorporate this into their own personal decision-making. So in this particular update, we reviewed evidence particularly pertaining to EGFR-mutated non–small cell lung cancer and non–small cell lung cancer harboring an NRG1 fusion. Brittany Harvey: Yes, certainly there's a lot of new evidence in the advanced non–small cell lung cancer field, and so we appreciate the panel's continuous review of this evidence. So then you just mentioned two separate areas where the panel reviewed new evidence. So starting with that first one, what updated evidence did the panel review on first-line treatment options for patients with EGFR alterations, and how did this impact the recommendations? Dr. Joshua Reuss: Yes, so advanced EGFR-mutated non–small cell lung cancer, at least with classical activating alterations - that is our exon 19 deletions and our exon 21 L858R mutations - is something that's really evolved rapidly in the last few years. You know, for many years, we basically, for the frontline treatment setting, were saying, "Okay, we have a targeted therapy, osimertinib. We're going to give that, and we're going to see what effect we can get out of that," with, you know, a median time of duration of treatment response averaging around 18 months, knowing that there are some that that's a lot longer and some that are a lot shorter. But recently, we've seen a lot of data emerging on combination strategies. The guideline has already been updated to incorporate two of these combinations: osimertinib with chemotherapy based off of the FLAURA2 trial, and then the combination of amivantamab with lazertinib based off of the MARIPOSA trial. And that was data on progression-free survival that was published and led to those particular recommendations. Now, more recently, we've seen data come out in smaller, randomized studies for other combinations. And more recently, we revi

Dr. Lyudmila Bazhenova is back on the podcast to discuss the latest update of the living guideline on therapy for stage IV NSCLC without driver alterations. She shares the studies the Expert Panel reviewed in the first- and second-line settings, including NIPPON, HARMONi-2, and DUBLIN-3.

It's great to have you back on the show today, Dr Bazhenova. Dr. Lyudmila Bazhenova: It's my pleasure to be here. Brittany Harvey: And then before we discuss this guideline update, I'd like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO conflict of interest policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Bazhenova, who has joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes. So then to dive into the content here, Dr. Bazhenova, this living clinical practice guideline for systemic therapy for patients with stage IV non–small cell lung cancer without driver alterations is updated on an ongoing continuous basis. So what prompted this latest update to the recommendations? Dr. Lyudmila Bazhenova: Living ASCO guidelines are designed to keep pace with rapidly evolving evidence that impacts treatment of our patients with lung cancer. As a committee, we are tasked with regular review of the published literature and determine if the new data warrants changes to existing recommendations. So in this recently published update, we evaluated new trials related to treatment of patients with metastatic lung cancer without driver alterations. Brittany Harvey: Excellent. Thank you for that explanation of the process. So, you just mentioned that the panel reviewed new trials for this update. So, which particular updated evidence did the panel review on first-line treatment options for patients with good performance status across histology and PD-L1 expression status, and how did this impact the recommendations? Dr. Lyudmila Bazhenova: For the first-line treatment option for patients without driver alterations, two studies met our criteria for review. One was the NIPPON trial from Japan, the second was the HARMONi trial. None of those two trials resulted in change in our guidelines, but I think they are giving us some additional information that would be useful for the way we treat patients with non–small cell lung cancer without driver alterations. For example, if we take those patients, we currently have several treatment options as a first line. One is monotherapy immunotherapy. You can give pembrolizumab as an example, and that was based on the KEYNOTE-024 and KEYNOTE-042 trials. Then we have a platinum doublet plus immunotherapy, and there are several trials that did that pathway. And then we have also an option of giving our patients dual IO immunotherapy combination, such as CheckMate 9LA and POSEIDON. At this point, we do not have any randomized trials comparing those three treatment modalities head-to-head. And the NIPPON trial was interesting to us because it was the first trial to compare CheckMate 9LA regimen, which is again, dual immunotherapy plus chemo, versus KEYNOTE-189 or KEYNOTE-407, which is a chemotherapy plus immunotherapy. And as a result of the study, while chemotherapy plus ipilimumab-nivolumab led to numerically higher overall survival, the difference was not statistically significant. And what is concerning in that trial is that we saw a higher number of treatment-related death occurring in nivolumab and ipilimumab arm compared to the pembrolizumab-chemotherapy arm.

They review updates to domain one, on key patient-centered quality standards on health equity and social determinants of health, drug access, patient safety, education, and adherence to maximize treatment outcomes and domain two, on key operational quality standards on logistics, care coordination, and waste prevention. We also cover the impact of these updated standards for clinicians, oncology practices, and people receiving oral anti-cancer medications. Read the complete standards, "Medically Integrated Dispensing Pharmacy: ASCO-NCODA Standards." Transcript These standards, clinical tools, and resources are available on ASCO.org. Read the full text of the guideline and review authors' disclosures of potential conflicts of interest in the JCO Oncology Practice. Brittany Harvey: Hello, and welcome to the ASCO Guidelines podcast, one of ASCO's podcasts delivering timely information to keep you up to date on the latest changes, challenges, and advances in oncology. You can find all the shows, including this one, at asco.org/podcasts. My name is Brittany Harvey, and today I'm interviewing Michael Reff from the Network of Collaborative Oncology Development and Advancement and Dr. Luis Raez from Memorial Cancer Institute and Florida Atlantic University, co-chairs on "Medically Integrated Dispensing Pharmacy: American Society of Clinical Oncology – Network of Collaborative Oncology Development and Advancement Association Standards Update." Thank you for being here, Michael and Dr. Raez. Dr. Luis Raez: Thanks for inviting us. Michael Reff: Thank you for having us. Brittany Harvey: Then, before we discuss these standards, I'd like to note that ASCO takes great care in the development of its standards and ensuring that the ASCO Conflict of Interest policy is followed for each guidance product. The disclosures of potential conflicts of interest for the expert panel, including Michael and Dr. Luis Raez who have joined us here today, are available online with the publication of the standards in JCO Oncology Practice, which is linked in the show notes. So then, to dive into the content here, Michael, I'd like to start with what prompted an update to these ASCO-NCODA standards and what is the scope of this update? Michael Reff: Thank you, Brittany. What led NCODA and ASCO to endeavor in this, and it started back in 2019 as the amount of oral anticancer medications became more and more prevalent in cancer treatment, we saw the need providing a blueprint for excellence in care for patients prescribed oral anticancer medications, specifically in the outpatient setting. And the update was driven by the rapid growth of these oral oncolytics starting back in the mid to late 2015 through 2019 or so, and then continued on into the 2020s where we are today. We saw the increase in the complexity of the management of these patients with these therapies basically outside the traditional clinical settings. And we wanted to make sure that with more cancer treatments that are taken at home than just at the clinic, like in the oral setting, new challenges had emerged around patient safety, access, adherence, and overall treatment success. The updates now address patient-centered and operational interventions designed to improve access, safety, quality, accountability, and outcomes of oral anticancer and other supportive care medications prescribed for the cancer patient. Dr. Luis Raez: As Mike said, these guidelines help improve patient care tremendously, but also help us a lot as an oncologist, you know, community oncologists that- now that we have opportunity to dispense these oral oncolytics, we need help to create our medical integrated pharmacies, and NCODA is providing here a way that, how to do this safely, efficaciously, good quality, you know? So that's why I think we always do everything for the patients, but also this helps a lot to the doctors. And there are a lot of what we call specialty pharmacies or medical integrated pharmacies now nationwide. Michael Reff: I'll build on what Dr. Raez had mentioned. This is the impetus. If you looked at the innovation that was coming from the pharmaceutical companies, many of it coming in the oral form for anticancer medications, and based on that, taking a look at the infrastructure that is in place in these practices, whether it's in the community or the IDN or health system settings, this amount of innovation that was coming needed to be addressed by taking a look at the medically integrated oncology team. And these standards address not just the pharmacy component, but also the whole continuum of care, starting with a medical oncologist or the hematologist, with the pharmacists, nurses, the pharmacy technicians, others that are involved in the care of the patient. And there were no standards involved. And when we approached ASCO back in 2018 to event

Brittany Harvey: Hello and welcome to the ASCO Guidelines Podcast, one of ASCO's podcasts delivering timely information to keep you up to date on the latest changes, challenges, and advances in oncology. You can find all the shows, including this one, at asco.org/podcasts. My name is Brittany Harvey and today I'm interviewing Dr. Kim Perez from Dana-Farber Cancer Institute and Dr. Jaydira Del Rivero from the Center for Cancer Research at the National Cancer Institute, co-chairs on "Symptom Management for Well-Differentiated Gastroenteropancreatic Neuroendocrine Tumors: ASCO Guideline." Thank you for being here today, Dr. Del Rivero and Dr. Perez. Dr. Kim Perez: Thank you. Dr. Jaydira Del Rivero: Thank you so much for the invitation. Brittany Harvey: And then before we discuss this guideline, I'd like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO Conflict of Interest Policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Perez and Dr. Del Rivero, who have joined us here today, are available online with the publication of the guideline in JCO Oncology Practice, which is linked in the show notes. So then to jump into the content here, first Dr. Del Rivero, could you provide an overview of the scope and purpose of this guideline? Dr. Jaydira Del Rivero: Yeah. Thank you so much. Well, first, we really wanted to thank ASCO for allowing us to develop these guidelines for the management of gastroenteropancreatic neuroendocrine tumors. I do want to mention that there is also another set of guidelines that I was very fortunate also to co-chair with Dr. Perez on the systemic management of gastroenteropancreatic neuroendocrine tumors. But when discussing these guidelines as well as with the different panelists, experts in this type of disease, we also realized that the management of these tumors are quite complex, not only from the management of the disease progression, but at the same time, management of the symptoms related to the hormone excess. And because of that, we like to thank ASCO for allowing us to then not only have a discussion on the systemic management of these tumors, but at the same time develop recommendations for the symptoms related to the different hormones that these neuroendocrine tumors may produce. These guidelines are for the management of grade 1 to grade 3 metastatic gastroenteropancreatic neuroendocrine tumors. These guidelines include the management of the different aspects and the symptoms related to hormone excess, such as carcinoid syndrome, carcinoid heart disease, how to manage carcinoid crisis, as well as the different symptoms and how to manage the functional pancreatic neuroendocrine tumors and as well as provide recommendations in the different treatments for these tumor types, not only from the systemic management but also from the surgical management as well as for liver-directed therapy options and the different aspects in terms of the palliative care of these patients to improve not only the symptoms related to the hormone excess caused by these tumors, but as well as to improve the quality of life. Brittany Harvey: Absolutely. And I appreciate that overview. And yes, we'll link the guideline on the Systemic Therapy for Tumor Control for Well-Differentiated Gastroenteropancreatic Neuroendocrine Tumors in the show notes for our listeners so that they can refer to that companion guideline as well. So then you just described the several different categories of recommendations that this guideline covers on symptom management. So, Dr. Perez, I'd like to start reviewing some of those key recommendations of that guideline. So, starting with what are the key recommendations for carcinoid syndrome and carcinoid heart disease? Dr. Kim Perez: Thank you Brittany. Yeah, I also want to thank ASCO for inviting us to do this podcast today. Just to start, I think these guidelines will really add to wha

Dr. Rohan Garje shares the updated recommendations for the ASCO guideline on systemic therapy for patients with metastatic castration-resistant prostate cancer. He discusses the systemic therapy options for patients based on prior therapy received in the castration-sensitive and non-metastatic castration-resistant settings. He emphasizes personalizing treatment choices for each individual, considering patient-specific symptoms and signs, treatment-related toxicities, potential drug interactions, cost, and access. He also reviews recommendations on response assessment. The conversation wraps up with a discussion of potential future updates to this guideline, as the guideline transitions into a "living guideline" on mCRPC.

My name is Brittany Harvey and today I'm interviewing Dr. Rohan Garje from Miami Cancer Institute Baptist Health South Florida, lead author on, "Systemic Therapy in Patients with Metastatic Castration-Resistant Prostate Cancer: ASCO Guideline Update." Thank you for being here today, Dr. Garje. Dr. Rohan Garje: Absolutely. Thank you so much for having me, Brittany. Brittany Harvey: And then before we discuss this guideline, I'd like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO Conflict of Interest Policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Garje, who has joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes. So then, to start on the content of this guideline, first, could you provide us an overview of the purpose of this guideline update? Dr. Rohan Garje: Sure. So ASCO has guidelines for prostate cancer and the specific guideline which we have updated for metastatic castrate-resistant prostate cancer was originally published in 2014. It's almost a decade. It's been a long time due for an update. Over the last decade, we have seen a lot of advances in the treatment of prostate cancer, specifically with regards to genomic testing, newer imaging modalities, and also the treatment landscape. Now we have newer options based on genomic targets such as PARP inhibitors, we have radiopharmaceuticals, a newer variant of chemotherapy, and also some specific indications for immunotherapy which were not addressed previously. Because all these advances have been new, it was really important for us to make an update. In 2022, we did make a rapid update with lutetium-177, but these additional changes which we have seen made it an appropriate time frame for us to proceed with a newer guideline. Brittany Harvey: Absolutely. It's great to hear about all these advances in the field to provide new options. So I'd like to next review the key recommendations from this guideline. So let's start with the overarching principles of practice that the panel outlined. What are these key principles? Dr. Rohan Garje: As a group, all the panel members came up with some ground rules: What are necessary for all our patients who are being treated for metastatic CRPC? First, the founding aspect was a definition for what is metastatic CRPC. So we defined metastatic CRPC as castrate level of testosterone with evidence of either new or progressive metastatic disease on radiological assessments or patients who have two consecutive rising PSAs in the setting of existing metastatic disease. We also emphasized on the need for germline and somatic testing for patients with metastatic prostate cancer at an earliest available opportunity because it is critical to select appropriate treatment and also right treatment for patients at the right time. And we actually have a concurrent guideline which addresses what genes to be tested and the timing. The other principles are patients should continue to receive androgen deprivation therapy or undergo surgical castration to maintain castrate level of testosterone. Now the key aspect with these guidelines is personalizing treatment choices. As you can see the evolution of treatment options for prostate cancer, the drugs that were initially developed and approved for prostate cancer were primarily in castrate-resistant settings, but now most of these drugs are being utilized in castrate-sensitive. So, wh

My name is Brittany Harvey and today I'm interviewing Dr. Jaishri Blakeley from Johns Hopkins University School of Medicine and Dr. Nimish Mohile from the Department of Neurology and Wilmot Cancer Institute at the University of Rochester Medical Center, co-chairs on "Therapy for Diffuse Astrocytic and Oligodendroglial Tumors in Adults: American Society of Clinical Oncology-Society for Neuro-Oncology Guideline Rapid Recommendation Update." Thank you for being here today, Dr. Blakeley and Dr. Mohile. Dr. Jaishri Blakeley: Thank you. Dr. Nimish Mohile: Thank you for having us. Brittany Harvey: And then before we discuss this guideline, I'd like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO Conflict of Interest Policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Blakeley and Dr. Mohile who have joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes. So then, to jump into the content here, Dr. Mohile, could you start us off by describing what prompted this rapid update to the ASCO-SNO therapy for diffuse astrocytic and oligodendroglial tumors in adults guideline, which was previously published in 2021? Dr. Nimish Mohile: Yeah. So the key reason for this update is the publication of a study in 2023. And this was a study called the INDIGO study that looked at a new class of therapies, something called IDH inhibitors. And in this study with a drug called vorasidenib, changed how we think about the treatment of oligodendrogliomas and astrocytomas, so particularly the grade 2 oligodendrogliomas and grade 2 astrocytomas. Because of the results of that study, we decided that we needed to do an update to inform clinicians about some of these changes and how we might approach these tumors differently today. Brittany Harvey: Great. I appreciate that background. So then, based off the new data from the INDIGO study, what are the updated and new recommendations from the expert panel? Dr. Nimish Mohile: So the key findings from the INDIGO study involved people who had grade 2 astrocytomas and grade 2 oligodendrogliomas. And in the setting after surgery, they were treated with vorasidenib, and what they found is that this delayed the time to next intervention. And the key aspect of that is that it delayed when we could start radiation and chemotherapy in these patients. So what we did in the guidelines is that for both low grade oligodendrogliomas and low grade astrocytomas, we added one additional guideline statement. Our previous guideline in 2021 offered the options for observation or treatment with radiation and chemotherapy. And now in this guideline, we have options for observation, treatment with vorasidenib in those in whom we feel it is safe to defer radiation and chemotherapy, and then treatment with radiation and chemotherapy. So we've added in an additional option here. And the key message of the guideline is really on how, as clinicians, we think about using the vorasidenib and what the ideal setting for using the vorasidenib is. Brittany Harvey: Excellent. It's great to hear about this new option for patients. So then you were just talking about how we think about who to offer this IDH inhibitor to. So, Dr. Blakeley, what should clinicians know as they implement these new recommendations into practice? Dr. Jaishri Blakeley: Yes. So, first and foremost, let's go back to 2021, and a key note from those guidelines was the importance of molecular testing. And at that point, the importance of molecular testing, which in large part was focused on IDH1 or IDH2 mutations, was prognostic. We could say there's a difference in an IDH1 mutant astrocyto

Dr. Ko Un "Clara" Park and Dr. Mylin Torres present the latest evidence-based changes to the SLNB in early-stage breast cancer guideline. They discuss the practice-changing trials that led to the updated recommendations and topics such as when SLNB can be omitted, when ALND is indicated, radiation and systemic treatment decisions after SLNB omission, and the role of SLNB in special circumstances. We discuss the importance of shared decision-making and other ongoing and future de-escalation trials that will expand knowledge in this space.

You can find all the shows, including this one at asco.org/podcasts. My name is Brittany Harvey and today I'm interviewing Dr. Ko Un "Clara" Park from Brigham and Women's Hospital, Dana-Farber Cancer Institute, and Dr. Mylin Torres from Glenn Family Breast Center at Winship Cancer Institute of Emory University, co-chairs on "Sentinel Lymph Node Biopsy in Early-Stage Breast Cancer: ASCO Guideline Update." Thank you for being here today, Dr. Park and Dr. Torres. Dr. Mylin Torres: Thank you, it's a pleasure to be here. Brittany Harvey: And before we discuss this guideline, I'd like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO Conflict of Interest Policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Torres and Dr. Park, who have joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes. To start us off, Dr. Torres, what is the scope and purpose of this guideline update on the use of sentinel lymph node biopsy in early-stage breast cancer? Dr. Mylin Torres: The update includes recommendations incorporating findings from trials released since our last published guideline in 2017. It includes data from nine randomized trials comparing sentinel lymph node biopsy alone versus sentinel lymph node biopsy with a completion axillary lymph node dissection. And notably, and probably the primary reason for motivating this update, are two trials comparing sentinel lymph node biopsy with no axillary surgery, all of which were published from 2016 to 2024. We believe these latter two trials are practice changing and are important for our community to know about so that it can be implemented and essentially represent a change in treatment paradigms. Brittany Harvey: It's great to hear about these practice changing trials and how that will impact these recommendation updates. So Dr. Park, I'd like to start by reviewing the key recommendations across all of these six overarching clinical questions that the guideline addressed. So first, are there patients where sentinel lymph node biopsy can be omitted? Dr. Ko Un "Clara" Park: Yes. The key change in the current management of early-stage breast cancer is the inclusion of omission of sentinel lymph node biopsy in patients with small, less than 2 cm breast cancer and a negative finding on preoperative axillary ultrasound. The patients who are eligible for omission of sentinel lymph node biopsy according to the SOUND and INSEMA trial are patients with invasive ductal carcinoma that is size smaller than 2 cm, Nottingham grades 1 and 2, hormone receptor-positive, HER2-negative in patients intending to receive adjuvant endocrine therapy, and no suspicious lymph nodes on axillary ultrasound or if they have only one suspicious lymph node, then the biopsy of that lymph node is benign and concordant according to the axillary ultrasound findings. The patients who are eligible for sentinel lymph node biopsy omission according to the SOUND and INSEMA trials were patients who are undergoing lumpectomy followed by whole breast radiation, especially in patients who are younger than 65 years of age. For patients who are 65 years or older, they also qualify for omission of sentinel lymph node biopsy in addition to consideration for radiation therapy omission according to the PRIME II and CALGB 9343 clinical trials. And so in those patients, a more shared decision-making approach with the radiation oncologist is encouraged. Brittany Harvey: Understood. I appreciate you outlining that criteria for when sentinel lymph node biopsy can be omitted and when shared decision making is appropriate as wel
