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).

Rutika Mehta, MD, MPH, of the H. Lee Moffitt Cancer Center and Research Institute, discusses the 3-year regression-free and overall survival results from the JACCRO study, which compared the efficacy of S-1, an oral prodrug of fluorouracil, vs S-1 plus docetaxel after curative resection of stage III gastric cancer (Abstract 159).
The ASCO Post Staff
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.

Talia Golan, MD, of the Oncology Institute, Sheba Medical Center, discusses phase III results from the POLO trial, which explored the question of whether maintenance olaparib could improve overall and progression-free survival for patients with germline BRCA-mutated metastatic pancreatic cancer (Abstract 378).

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).

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).
