Ingrid A. Mayer, MD, on Triple-Negative Breast Cancer: Platinum-Based Chemotherapy vs Capecitabine
2021 ASCO Annual Meeting
Ingrid A. Mayer, MD, of Vanderbilt University Medical Center, discusses phase III results from a trial that showed patients with triple-negative breast cancer who had residual invasive disease after neoadjuvant chemotherapy had lower-than-expected invasive disease–free survival, regardless of study treatment with platinum-based chemotherapy or capecitabine (Abstract 605).

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).

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).

Brian K. Link, MD, of the University of Iowa Carver College of Medicine, reviews three abstracts on state-of-the-art therapies for mantle cell lymphoma: bendamustine, rituximab, lenalidomide and bortezomib; treatment patterns and outcomes for previously untreated patients; and venetoclax, lenalidomide, and rituximab in newly diagnosed disease (Abstracts 7503, 7504, and 7505).

Sumanta K. Pal, MD, of City of Hope, discusses results from a phase II study that sought to determine whether adding berzosertib, a selective ATR inhibitor, to the standard upfront chemotherapy regimen of cisplatin with gemcitabine may improve outcomes in patients with metastatic urothelial carcinoma (Abstract 4507).

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).
