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.
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).
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).
Jennifer Ho, MD, of The University of Texas MD Anderson Cancer, discusses study results on the use of intensity-modulated proton therapy, which can provide durable local control with minimal toxicity in patients who can have extended survivals; the data also suggest that higher doses may improve outcomes (Abstract 5).
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).
Douglas E. Wood, MD, of the University of Washington, discusses the importance of broad access to and education about lung cancer screening—now approved for people at high risk for the disease—and the need for expanded criteria for screening eligibility.
