Richard J. Cassidy III, MD, of Emory Winship Cancer Institute, discusses results from a multicenter analysis of stereotactic body radiotherapy for early-stage non-small cell lung cancer in patients 80 years and older; the patients tolerated the treatment well and had excellent estimated rates of 5-year cancer-specific survival (Abstract 111).
Zhongxing Liao, MD, of The University of Texas MD Anderson Cancer Center, discusses the continued improvement in planning, delivery, and patient selection for proton therapy, which can both reduce radiation exposure and increase tumor dose.
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).
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.
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).
