Nadia Harbeck, MD, PhD, on Early Breast Cancer: Benefit of a De-escalated Regimen
2021 ASCO Annual Meeting
Nadia Harbeck, MD, PhD, of Ludwig Maximilian University of Munich, discusses results from the ADAPT HR–/HER2+ trial, which showed, for the first time, improved pathologic complete response and survival in patients with early breast cancer who were treated weekly with a de-escalated 12-week regimen of neoadjuvant paclitaxel plus pertuzumab and trastuzumab (Abstract 503).

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).

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).

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).

Toni K. Choueiri, MD, of Dana-Farber Cancer Institute, discusses phase III results from KEYNOTE-564, which evaluated the safety and efficacy of pembrolizumab in the adjuvant treatment of patients with renal cell carcinoma who have undergone nephrectomy for intermediate-high or high-risk disease or no evidence of disease (Abstract LBA5).

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).
