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).
Matt D. Galsky, MD, of the Tisch Cancer Institute at Icahn School of Medicine at Mount Sinai, discusses results from a phase II trial designed to test gemcitabine and cisplatin plus nivolumab as neoadjuvant therapy in patients with muscle-invasive bladder cancer and to better predict benefit in those who opted out of cystectomy (Abstract 4503).
Melinda L. Telli, MD, of Stanford University, discusses results of a phase II study on neoadjuvant talazoparib in germline BRCA1/2 mutation–positive, early HER2-negative breast cancer. In this setting, talazoparib monotherapy was active and yielded pathologic complete response rates comparable to those observed with combination anthracycline and taxane-based chemotherapy regimens (Abstract 505).
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).
Ian Chau, MD, of Royal Marsden NHS Foundation Trust, discusses first results of the CheckMate 648 study, which showed that nivolumab plus chemotherapy and nivolumab plus ipilimumab both demonstrated superior overall survival vs chemotherapy alone in patients with advanced esophageal squamous cell carcinoma. These regimens may represent potential new first-line treatment options (Abstract 4001).
Debora S. Bruno, MD, of Seidman Cancer Center at Cleveland Medical Center, discusses study findings that show Black patients with advanced or metastatic non–small cell lung cancer tend to be less likely to undergo biomarker testing or to be treated in clinical trials than White patients. Recommended broad-based testing, says Dr. Bruno, may help ensure equal access to quality care and clinical trials (Abstract 9005).
