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).
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.
Ramesh K. Ramanathan, MD, of the Mayo Clinic, discusses early-phase study findings on mFOLFIRINOX (mFFOX) plus pegylated recombinant human hyaluronidase vs mFFOX alone in patients with a good performance status (Abstract 208).
Mark Saunders, MD, PhD, of Christie Hospital, discusses study findings on tumor sidedness and the influence of chemotherapy duration on disease-free survival (Abstract 558).
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).
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).
