David H. Ilson, MD, PhD, of Memorial Sloan Kettering Cancer Center, discusses the merits of preoperative chemotherapy vs chemoradiotherapy, the role of targeted agents, recent results from genomic profiling, and whether PET scans can guide neoadjuvant treatment.
Maria Svensson, MD, PhD Candidate, of Lund University, discusses high expression of PD-1 and PD-L1 in chemotherapy-naive esophageal and gastric adenocarcinomas, the implications for survival, and the link to a deficiency in mismatched repair genes (Abstract 9).
Manish A. Shah, MD, of Weill Cornell Medicine, discusses phase III study findings on cisplatin plus capecitabine or fluorouracil with or without ramucirumab as first-line therapy in patients with metastatic gastric or gastroesophageal junction adenocarcinoma (Abstract 5).
Pieter van der Sluis, MD, PhD, of the University Medical Center Utrecht, discusses study findings that compared robot-assisted minimally invasive thoracolaparoscopic esophagectomy vs open transthoracic esophagectomy for resectable esophageal cancer (Abstract 6).
Steven D. Leach, MD, of Dartmouth University’s Norris Cotton Cancer Center, discusses the personalized approach that GI cancers will require to make rational use of immunotherapy—including a subset of pancreatic cancers, which appear to be highly immunogenic and are associated with long-term survival.
Thierry André, MD, of Hôpital Saint-Antoine, and Michael J. Overman, MD, of The University of Texas MD Anderson Cancer Center, discuss findings from their respective CheckMate-142 studies on nivolumab and ipilimumab in patients with DNA mismatch repair–deficient/microsatellite instability–high metastatic colorectal cancer (Abstracts 553, 554).
