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).

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).

Byoung Chul Cho, MD, PhD, of the Yonsei Cancer Center, discusses study results that showed treatment with the EGFR-MET bispecific antibody amivantamab plus the EGFR inhibitor lazertinib yielded responses in 36% of chemotherapy-naive patients with non–small cell lung cancer whose disease progressed on osimertinib. Genetic biomarkers may be able to identify patients most likely to benefit from the combination regimen (Abstract 9006).

Terry P. Mamounas, MD, MPH, of the University of Florida Health Cancer Center, discusses results from the NRG Oncology/NSABP B-42 study, which examined the Breast Cancer Index and its ability to predict whether extended treatment with letrozole benefits patients with hormone receptor–positive breast cancer (Abstract 501).

Neeraj Agarwal, MD, of Huntsman Cancer Institute at the University of Utah, discusses phase III data from the SWOG S1216 trial, which evaluated the clinical benefit of using androgen-deprivation therapy with either orteronel (or TAK-700, a CYP17 inhibitor) or bicalutamide in patients with newly diagnosed metastatic hormone-sensitive prostate cancer (Abstract 5001).
