Kai-Keen Shiu, MD, PhD, on Colorectal Cancer: Pembrolizumab vs Chemotherapy for Microsatellite Instability–High Disease
2021 Gastrointestinal Cancers Symposium
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).

Milind M. Javle, MD, of The University of Texas MD Anderson Cancer Center, discusses phase II study results showing that the novel tyrosine kinase inhibitor infigratinib may prove to be effective in treating patients with advanced cholangiocarcinoma harboring an FGFR2 gene fusion or rearrangement (Abstract 265).

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).

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).

Zev A. Wainberg, MD, of UCLA Medical Center, discusses phase II results from the FIGHT study, which combined bemarituzumab with modified FOLFOX6 in first-line treatment of advanced gastric/gastroesophageal junction adenocarcinoma. This is reportedly the first randomized trial of any FGFR inhibitor, validating this target in gastric cancer (Abstract 160).

Afsaneh Barzi, MD, PhD, of the City of Hope Comprehensive Cancer Center and the University of Southern California, discusses reasons for the incomplete understanding of the molecular landscape of minority patients with cancer, lack of screening chief among them. This underrepresentation, Dr. Barzi says, is more marked in gastrointestinal malignancies than other solid tumors, and she recommends ways to improve the outlook.
