Therapy for Stage IV Non–Small-Cell Lung Cancer Without Driver Alterations Guideline ASCO Guidelines

An interview with Dr. Nasser Hanna from Indiana University Simon Cancer Center and Dr. Gregory Masters from Helen F. Graham Cancer Center and Research Institute on "Therapy for Stage IV Non-Small-Cell Lung Cancer Without Driver Alterations: ASCO and OH (CCO) Joint Guideline Update." This guideline provides recommendations on systemic therapy treatment options for patients with stage IV non-small-cell lung cancer (NSCLC) without driver alterations in epidermal growth factor receptor or ALK, based on histology, PD-L1 status, and/or the presence or absence of contraindications.

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 podcasts.asco.org.

My name is Brittany Harvey. And today, I'm interviewing Dr. Nasser Hanna from Indiana University's Simon Cancer Center and Dr. Gregory Masters from Helen F. Graham Cancer Center and Research Institute, co-chairs on therapy for stage IV, non-small cell lung cancer without driver alterations, ASCO and CCO Joint Guideline Update. Thank you for being here today Dr. Hanna and Dr. Masters.

Thank you. Glad to be with you.

My pleasure. Thanks.

First, Dr. Hanna, can you give us a general overview of what this guideline covers?

Sure. So the ASCO guidelines for the treatment of patients with stage IV, non-small cell lung cancer were last updated in 2017. And since that time, there has been a tremendous amount of change that has taken place. The 2017 guidelines included recommendations for basically three subgroups-- those patients with non-small cell lung cancer who have certain targetable DNA mutations and those who do not have those mutations but have a PD-L1 score of 50% or higher and then everyone else.

But because of the rapid and vast changes that have taken place, we decided to make a separate guideline for those with targetable DNA mutations and to focus this current guideline on those without the targetable mutations. So within that context, this guideline categorizes patients by whether their tumors have a PD-L1 score of 0% to 49% or those who have a PD-L1 score or 50% or greater.

And within those categories, recommendations are characterized based upon whether the patient has squamous cell histology or non-squamous cell histology. And we also consider whether patients are candidates for chemotherapy or perhaps even those that decline chemotherapy and whether they have any contraindications for immunotherapy.

So what distinguishes these guidelines from other guidelines is our attempt to adhere to the strongest available evidence-based medicine. And while not every iteration of clinical management can be covered, these guidelines provide oncologists with a strong, evidence-based roadmap to treat the vast majority of patients with non-small cell lung cancer.

So as a result of this collective effort by ASCO staff and the guideline writing committee, this report offers a substantial amount of change to the recommendations from the clinical practices guidelines provided in 2017. In 2017, the only recommendations for the use of immunotherapy were in the first line setting for patients who had a PD-L1 score of greater than 50% and in the second line setting of patients progressing after first line chemo.

But these
