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).
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).
Massimo Cristofanilli, MD, of the Feinberg School of Medicine at Northwestern University, discusses updated overall survival data from the phase III PALOMA-3 trial of palbociclib plus fulvestrant in women with hormone receptor–positive, HER2-negative advanced breast cancer (Abstract 1000).
Nadia Harbeck, MD, PhD, of Ludwig Maximilian University of Munich, discusses first phase III results from a prospective high-risk cohort of patients with luminal breast cancer, which showed a good prognosis in some women with more than four positive lymph nodes and low recurrence scores. The study also showed that a lower postendocrine Ki67 index and limited tumor burden may be promising criteria for chemotherapy de-escalation strategies, even in patients with high recurrence scores (Abstract 504).
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).
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).
