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).
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).
Romain Cohen, MD, PhD, of the Mayo Clinic and Sorbonne University, discusses a post-hoc analysis of phase III results from the CALGB/SWOG 80702 study, which showed that adding the number of tumor deposits, a negative prognostic factor, to the count of lymph node metastases may improve the accuracy of TNM staging (Abstract 10).
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).
Andrew X. Zhu, MD, PhD, of Massachusetts General Hospital, discusses final results from the phase III ClarIDHy study, which showed that ivosidenib may improve overall and progression-free survival compared with placebo in patients with previously treated cholangiocarcinoma and an isocitrate dehydrogenase 1 mutation (Abstract 266).
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).
