Thierry André, MD, on Colorectal Cancer: Pembrolizumab vs Chemotherapy for Metastatic Disease
ASCO20 Virtual Scientific Program
Thierry André, MD, of Hôpital Saint-Antoine, discusses the phase III results from KEYNOTE-177, which showed that, compared with standard chemotherapy of FOLFOX or FOLFIRI, pembrolizumab doubled median progression-free survival, from 8.2 months to 16.5 months, in patients with microsatellite instability–high/mismatch repair–deficient metastatic colorectal cancer (Abstract LBA4).

Cynthia X. Ma, MD, PhD, of Washington University, discusses results from the ALTERNATE trial, which showed neither fulvestrant nor fulvestrant plus anastrozole significantly improved endocrine-sensitive disease rate compared with anastrozole alone in postmenopausal patients with locally advanced estrogen receptor–positive, HER2-negative breast cancer (Abstract 504).

David R. Wise, MD, PhD, of New York University Perlmutter Cancer Center, summarizes three important studies in prostate cancer: circulating tumor cell count as a prognostic marker of PSA response and progression in metastatic castration-sensitive disease; new phenotypic subtypes; and how circulating tumor DNA dynamics associate with treatment response and radiologic progression-free survival (Abstracts 5506, 5507, and 5508).

Scott Kopetz, MD, PhD, of The University of Texas MD Anderson Cancer Center, discusses phase III results of the BEACON CRC study, which confirmed that, compared with standard chemotherapy, encorafenib plus cetuximab with or without binimetinib improved overall survival and objective response rate in previously treated patients with BRAF V600E–mutated metastatic colorectal cancer (Abstract 4001).

Rana R. McKay, MD, of the University of California, San Diego, discusses the results of a phase II trial of intense neoadjuvant hormone therapy followed by radical prostatectomy in men with high-risk prostate cancer. The data show that 21% of patients had a favorable pathologic response (Abstract 5503).

Tingyan Shi, MD, PhD, of Zhongshan Hospital, Fudan University, discusses study results that showed secondary cytoreductive surgery in selected patients extended progression-free survival and might contribute to long-term survival (Abstract 6001).
