Zofia Piotrowska, MD, of the Massachusetts General Hospital Cancer Center, discusses heterogeneity and variation in resistance mechanisms among EGFR-mutant non–small cell lung cancer patients with at least one postresistance biopsy (Abstract 1).
Charles B. Simone, II, MD, of the University of Maryland Medical Center, discusses results from a large prospective study in locally advanced non–small cell lung cancer, which suggest that circulating tumor cells may be a promising biomarker of progressive or recurrent disease and may help guide early salvage treatment strategies (Abstract 3).
Boris Sepesi, MD, of The University of Texas MD Anderson Cancer Center, discusses immune cells within tumors and the potential role for checkpoint inhibitor therapy in the neoadjuvant setting of locally advanced lung cancer (Abstract 7).
Kamran Ahmed, MD, of the H. Lee Moffitt Cancer Center and Research Institute, discusses results from a small study of pneumonitis in patients who received thoracic radiotherapy within 6 months of anti–PD-1 therapy, anti–PD-L1 therapy, anti–CTLA-4 therapy, or some combination of these drugs (Abstract 10).
Martin J. Edelman, MD, of Fox Chase Cancer Center, discusses study findings from a phase III study of celecoxib in addition to standard chemotherapy for advanced non–small cell lung cancer with COX-2 overexpression (Abstract 2).
Maximilian Diehn, MD, PhD, of Stanford School of Medicine, discusses promising clinical applications of circulating tumor DNA in patients with thoracic malignancies: noninvasive detection of resistance mechanisms to targeted agents and treatment response assessment.
