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. William Dale from City of Hope National Medical Center, Dr. Heidi Klepin from Wake Forest Baptist Comprehensive Cancer Center, and Dr. Supriya Mohile from University of Rochester Medical Center—co-chairs on “Practical Assessment and Management of Vulnerabilities in Older Patients Receiving Systemic Cancer Therapy: ASCO Guideline Update.”  Thank you for being here, Dr. Dale, Dr. Klepin, and Dr. Mohile. Dr. William Dale: Nice to see you. Thanks for having us. Brittany Harvey: Then, before we discuss this guideline, I'd like to note that ASCO takes great care in the development of its guidelines and ensures that the ASCO conflict of interest policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including our guests joining us on this podcast episode today, are available online with the publication of the guideline in the Journal of Clinical Oncology linked in the show notes.  Diving into the content of this guideline first, Dr. Dale and Dr. Mohile, can you speak to what prompted an update of this ASCO guideline on the practical assessment and management of age-associated vulnerabilities in older patients undergoing systemic cancer therapy, which was previously published in 2018? Dr. William Dale: Sure. Yes. In 2018, that was the very first guideline for older adults that ASCO had created, and that was based on work that had been done up to that time, focused on chemotherapy toxicities. And to summarize what was put out at that time, the evidence was thought to be strong enough for doing geriatric assessments. And these are specialized assessments across a number of domains, including functional impairments, cognitive losses, social impairments, etc. But to do these kinds of geriatric assessments with validated tools; that a certain selection of these domains to cover everything that was relevant; to conduct non-cancer prognostication so that for decision-making purposes, if someone were to have their cancer cured, what would be their prognosis, and help make decisions about giving chemotherapy and what doses; and then to enact geriatric assessment-guided target interventions was the fourth recommendation. And so that's where we were in 2018.  In 2020 at ASCO, there was an oral session that had four randomized controlled trials that enrolled older adults. And in that was kind of the signal that there was more coming. And in 2021, two big trials that are practice-changing were published. One led by Dr. Mohile in Lancet that we call the GAP70+ study, and another one was published in JAMA Oncology. And they essentially showed the same thing, which was that GA-guided interventions could change the primary outcome, which was to reduce chemotherapy toxicity up to 20%, and also to affect a number of other outcomes. That, along with a number of other trials that have since come out and are included in the upcoming guidelines, and made it a high priority to update these guidelines. So that's where we got from there to here. And I think it's worth saying a few words about these new trials, particularly the GAP and GAIN studies. So the GAIN ...

    Cancer Cachexia Rapid Recommendation Update
    Jul 12 2023
    Dr. Charles Loprinzi shares the latest update to the management of cancer cachexia guideline. Dr. Loprinzi discusses the evidence that prompted the rapid update to the guideline and reviews the new evidence-based recommendations, including the addition of low-dose olanzapine as a treatment option for patients with advanced cancer to improve weight gain and appetite. Dr. Loprinzi reviews the limitations of the update, and outstanding research questions in the domain of cancer-associated cachexia.

You can find all the shows, including this one, at asco.org/podcasts. My name is Brittany Harvey, and today I'm interviewing Dr. Charles Loprinzi from Mayo Clinic, Co-Chair on “Cancer Cachexia: ASCO Guideline Rapid Recommendation Update.” Thank you for being here today, Dr. Loprinzi.  Dr. Charles Loprinzi: It's a pleasure to participate. Brittany Harvey: 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. Loprinzi who has joined us here today, are available in line with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes.   Then, to get into the content of this rapid recommendation update, first, Dr. Loprinzi, what prompted this rapid update to the ASCO management of cancer cachexia guideline, which was previously published in 2020? Dr. Charles Loprinzi: The impetus for the updated guideline was a recent JCO publication regarding the results of a randomized controlled trial looking at olanzapine. This prompted the expert panel to revisit this topic. The trial, conducted in India, involved 124 patients with stomach, hepatopancreatobiliary, or lung cancers as they initiated chemotherapy. Weight gain greater than 5% occurred in 60% of patients in the olanzapine arm versus 9% of the patients in the placebo arm with a p-value of 0.001 or less. Substantially improved appetite was seen in 43% versus 13%, with placebo also a p-value of less than 0.001. Grade 3 or greater chemotherapy toxicity was less common with olanzapine 12% versus 37%, with placebo with a p-value of 0.002. No substantial olanzapine-associated toxicity was apparent. There was one evidence of this with olanzapine versus two for placebo. So that was the reason for going ahead with this update. Brittany Harvey: I appreciate that background information. So then, based on this updated study on olanzapine, what are the updated recommendations from the expert panel for treating cancer cachexia? Dr. Charles Loprinzi: So, let me start to address this question by reviewing what the 2020 ASCO guidelines published said regarding the management of cancer cachexia in adults with advanced cancer. It concluded that evidence was insufficient to strongly endorse any pharmacologic agent for established anorexia/cachexia. Nonetheless, the guideline recommendation supported that clinicians could offer a short-term trial of a progesterone analog such as megestrol acetate or a corticosteroid such as dexamethasone to patients experiencing weight loss and/or appetite stimulation. These drugs stimulated appetite and caused weight gain, but they did not improve quality of life, they did not improve survival, and there was toxicity associated with these agents and therefore it was not strongly recommended.  The expert panel thoroughly discussed a potential role for olanzapine because of a couple of trials suggesting it was beneficial but concluded that the evidence was insufficient for a recommendation. Now, there was evidence from two randomized trials that supported olanzapine was an effective alternative for treating cancer-associated anorexia/cachexia. Thus, olanzapine was considered promising, but the data were not conclusive enough to support a guideline treatment recommendation. The new JCO publication was the impetus for making this guideline change. Brittany Harvey: Understood. So then, based off this new change to the recommendations, what is the breadth of these recommendations and what do these options mean for patients with advanced cancer?  Dr. Charles Loprinzi: The updated guidelines recommended that for adults ...

  • Therapy for Stage IV NSCLC With Driver Alterations: ASCO Living Guideline Update 2023.2

    Therapy for Stage IV NSCLC With Driver Alterations: ASCO Living Guideline Update 2023.2
    Jul 11 2023
    Dr. Navneet Singh highlights the latest evidence-based recommendation updates from the ASCO living guideline on stage IV non-small cell lung cancer with driver alterations. This update focuses on new second-line options for patients with advanced NSCLC and an EGFR exon 20 insertion, including amivantamab and mobocertinib. Dr. Singh also discusses updated results from CodeBreaK 200 and the option of second-line therapy with sotorasib for patients with advanced NSCLC and a KRAS-G12C mutation. Read the update, “Therapy for Stage IV Non-Small Cell Lung Cancer With Driver Alterations: ASCO Living Guideline, Version 2023.2” and view all recommendations at www.asco.org/living-guidelines.

Read the full text of the guideline and review authors’ disclosures of potential conflicts of interest disclosures in the Journal of Clinical Oncology, https://ascopubs.org/doi/10.1200/JCO.23.01055  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 am joined by Dr. Navneet Singh from the Postgraduate Institute of Medical Education and Research in Chandigarh, India, co-chair on “Therapy for Stage IV Non-Small Cell Lung Cancer with Driver Alterations: ASCO Living Guideline, Version 2023.2.” Thank you for being here, Dr. Singh.  Dr. Navneet Singh: Thank you for having me, Brittany. Brittany Harvey: 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. Singh, 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 this living clinical practice guideline, Dr. Singh, this living guideline for systemic therapy for stage IV non-small cell lung cancer with driver alterations is being routinely updated. What new studies were reviewed by the panel to prompt an update to the recommendations in this version? Dr. Navneet Singh: So for this 2023 version 2 update, three trials were included. These include two studies which involved patients with exon 20 insertion mutations, who had received prior platinum-based chemotherapy and subsequently were treated with either amivantamab in the CHRYSALIS trial or with mobocertinib in the EXCLAIM trial. The third trial which formed the basis for this update was one which involved patients with KRAS G12C mutation who had previously received systemic therapy and subsequently were treated with sotorasib. And this was the CodeBreaK 200 trial. Brittany Harvey: Understood. So then, based on these three new trials that you've just mentioned, what are the updated recommendations from the expert panel for patients with advanced non-small cell lung cancer? Dr. Navneet Singh: For patients with advanced NSCLC with an EGFR exon 20 insertion mutation and an ECOG performance status of 0 to 2 who have received prior platinum-based chemotherapy, clinicians may offer amivantamab or mobocertinib as monotherapy. It is important to mention here that in the absence of head-to-head comparison of amivantamab or mobocertinib with each other or with other standard second-line therapies, no recommendation for sequencing can be made and therefore treatment should be individualized. Now, use of either of the two drugs is based on low-quality evidence and has a weak strength of recommendation. And the updates for treating KRAS G12C-mutated NSCLC is largely similar; that patients who have received prior systemic therapy may be offered sotorasib.  Brittany Harvey: Thank you for reviewing those updated recommendations. So what should clinicians know as they implement these new recommendations and how do they interface with the existing recommendations? Dr. Navneet Singh: It is important for clinicians involved in the management of EGFR mutant lung cancer to realize that exon 20 insertions are the third most common group of EGFR mutations and comprise approximately 5% of all EGFR mutations. Now, historically, the EGFR targeted drugs which have been the first, second, or third generation tyrosine kinase inhibitors have largely shown efficacy for the two common types of EGFR mutations, namely the exon 19 deletions and the exon 21 L858R point mutation. Exon 20 insertion mutations thus did not have any effective targeted therapy so far. But now, both of these drugs, amivantamab and mobocertinib, have shown very promising results for pretreated patients with this molecular aberration and therefore may ...
