BRITTANY HARVEY: Hello, and welcome to the ASCO Guidelines podcast series, brought to you by the ASCO Podcast Network, a collection of nine programs covering a range of educational and scientific content and offering enriching insight into the world of cancer care. You can find all the shows, including this one, at ASCO.org/podcasts. My name is Brittany Harvey, and today, I'm interviewing Dr. Megan Daley from University of California in Davis, California, and Dr. Navneet Singh from the Post-Graduate Institute of Medical Education and Research in Chandigarh, India, co-chairs on management of stage III non-small cell lung cancer ASCO guideline. Thank you for being here, Dr. Daley and Dr. Singh. MEGAN DALEY: Thank you for having us. NAVNEET SINGH: Thank you for having us, too. BRITTANY HARVEY: First, 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 full conflict of interest information for this guideline panel is available online with the publication of the guideline in the Journal of Clinical Oncology. Dr. Daley, do you have any relevant disclosures that are directly related to this guideline topic? MEGAN DALEY: I have research funding from EMD Serono, Merck, and Genentech. BRITTANY HARVEY: Thank you for those disclosures. Then Dr. Singh, do you have any relevant disclosures that are directly related to this guideline? NAVNEET SINGH: No, I have no financial conflicts of interest. BRITTANY HARVEY: Thank you. Getting into the content of this guideline, Dr. Singh, can you give us an overview of both the scope and the purpose of this guideline? NAVNEET SINGH: Yes, absolutely. So this guideline has been developed to assist clinicians involved in the management of patients with stage III non-small-cell lung cancer, or NSCLC, as we call it briefly. Now, stage III NSCLC represents one of the most heterogeneous subgroups of lung cancer. Consequently, it is also the subgroup in which the choice of multimodality treatment and the sequence of multimodality treatment varies significantly amongst clinicians, with variations being observed across institutes, as well as within an institute. And we sincerely hope that, with the help of this guideline, clinicians can accurately confirm the presence of stage III disease and offer the most appropriate treatment based on clinical and radiographic characteristics, as well as other medical factors that influence treatment decision-making. This evidence-based guidance also seeks to provide clarification on the common clinical dilemmas that clinicians may have while evaluating a patient with suspected or known stage III NSCLC. BRITTANY HARVEY: Thank you for that background information, Dr. Singh. Then, Dr. Daley, this guideline addresses five main sections, evaluation and staging, surgery, neoadjuvant therapy, adjuvant therapy, and unresectable disease. So starting with evaluation and staging, what are the key recommendations for workup for patients with suspecte
