Andrew X. Zhu, MD, PhD, on IDH1-Mutant Cholangiocarcinoma: Ivosidenib vs Placebo
2021 Gastrointestinal Cancers Symposium
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).

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).

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).

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).

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).

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).
