Thierry André, MD, on Mismatch Repair–Deficient Solid Cancers: Safety and Efficacy of Dostarlimab
2021 Gastrointestinal Cancers Symposium
Thierry André, MD, of Hôpital Saint-Antoine, discusses results from the GARNET study, which showed that dostarlimab, an anti–PD-1 antibody, demonstrated durable antitumor activity in patients with mismatch repair–deficient colorectal and noncolorectal solid tumors. No new safety signals were detected, and most treatment-related adverse events were of a low grade (Abstract 9).

Kai-Keen Shiu, MD, PhD, of the University College Hospital NHS Foundation Trust - London, discusses an interim analysis of PFS 2 results (defined as time from random assignment to progression on the next line of therapy or death) from the phase III KEYNOTE-177 trial. This study has already shown that first-line pembrolizumab provides a clinically meaningful and statistically significant improvement in PFS compared with chemotherapy in patients with microsatellite instability–high metastatic colorectal cancer (Abstract 6).

Rocio Garcia-Carbonero, MD, of Hospital Universitario 12 De Octubre, discusses results of the phase II/III AXINET trial, which showed that axitinib plus long-acting release octreotide improved overall response compared with placebo and octreotide in patients with advanced grade 1 or 2 extrapancreatic neuroendocrine tumors. However, no significant improvement in progression-free survival was observed (Abstract 360).

Richard S. Finn, MD, of the UCLA Medical Center, discusses updated results from the IMbrave 150 study, which showed atezolizumab plus bevacizumab provides the longest overall survival seen in a front-line phase III study in advanced hepatocellular carcinoma, confirming this combination as the standard of care for patients with previously untreated, unresectable disease (Abstract 267).

Wasat Mansoor, MBChB, PhD, of The Christie NHS Foundation Trust, discusses phase III results from the KEYNOTE-590 trial, which showed no deterioration in health-related quality of life when pembrolizumab was added to chemotherapy in patients with metastatic and unresectable esophageal cancers (Abstract 168).

Matthew H.G. Katz, MD, of The University of Texas MD Anderson Cancer Center, discusses findings from the Alliance A021501 study, which showed that administering mFOLFIRINOX before surgery was associated with a favorable overall survival rate relative to historical data in patients with borderline resectable adenocarcinoma of the pancreas (Abstract 377).
