Thierry André, MD, on Pembrolizumab vs Chemotherapy in MSI-High Colorectal Cancer
2021 ASCO Annual Meeting
Thierry André, MD, of Hôpital Saint-Antoine, discusses final overall survival data for the phase III KEYNOTE-177 study, which confirmed pembrolizumab as a new standard of care for first-line treatment of patients with microsatellite instability–high/mismatch repair–deficient metastatic colorectal cancer (Abstract 3500).

Andrew Tutt, PhD, MBChB, of the Institute of Cancer Research, London, discusses findings from the phase III OlympiA trial, which showed that adjuvant olaparib, a PARP inhibitor, following adjuvant or neoadjuvant chemotherapy, may improve invasive disease–free survival in patients with germline BRCA-mutated and high-risk HER2-negative early breast cancer, which might lead to a new indication in this setting (Abstract LBA1).

Peter C. Black, MD, of the Vancouver Prostate Centre, University of British Columbia, reviews three studies on early detection and treatment of Black patients with prostate cancer: a large-scale analysis of genomic profiling; the use of PSA screening; and integrating a patient-specific genomic classifier to improve risk classification and treatment recommendations for Black men (Abstracts 5003, 5004, and 5005).

Linda R. Mileshkin, MBBS, MD, of the Peter MacCallum Cancer Centre, discusses phase III findings from the OUTBACK trial, which showed that adjuvant chemotherapy given after standard cisplatin-based chemoradiation for women with locally advanced cervical cancer did not improve either overall or progression-free survival (Abstract LBA3).

Cathy Eng, MD, of Vanderbilt-Ingram Cancer Center, discusses two abstracts from a session she co-chaired: the phase II DEEPER trial, which explored the use of FOLFOXIRI plus cetuximab vs FOLFOXIRI plus bevacizumab as first-line treatment in metastatic colorectal cancer with RAS wild-type tumors; and the phase II FIRE-4.5 study, which investigated FOLFOXIRI plus either bevacizumab or cetuximab as first-line treatment of BRAF V600E–mutant advanced disease (Abstracts 3501 and 3502).

Peter H. O’Donnell, MD, of The University of Chicago, discusses response and survival results from the phase II KEYNOTE-052 study, which showed that after up to 5 years of follow-up, pembrolizumab continued to elicit clinically meaningful, durable antitumor activity in cisplatin-ineligible patients with advanced urothelial cancer (Abstract 4508).
