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).

Tenna V. Henriksen, PhD Candidate, of Aarhus University, discusses her findings on how circulating tumor DNA may help assess recurrence risk and the benefit of adjuvant therapy, and more quickly detect early relapse after treatment in patients with colorectal cancer (Abstract 11).

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).

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.

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).
