Javier Cortés, MD, PhD, on Previously Untreated Triple-Negative Breast Cancer: Pembrolizumab Plus Chemotherapy
2021 San Antonio Breast Cancer Symposium
Javier Cortés, MD, PhD, of the International Breast Cancer Center, discusses the final phase III results of KEYNOTE-355, which showed that pembrolizumab and chemotherapy improved overall and progression-free survival, compared with placebo and chemotherapy, for patients with previously untreated, locally recurrent, inoperable or metastatic triple-negative breast cancer (Abstract GS1-02 ).

Peter Schmid, MD, PhD, of Barts Cancer Institute, discusses phase III findings from KEYNOTE-522, in which researchers found a generally consistent event-free survival benefit among patients with early-stage high-risk triple-negative breast cancer who were treated with neoadjuvant pembrolizumab plus chemotherapy followed by adjuvant pembrolizumab (Abstract GS1-01).

Patricia A. Ganz, MD, of the University of California, Los Angeles, discusses quality-of-life results from the phase III OlympiA study of adjuvant olaparib after (neo)adjuvant chemotherapy in patients with germline BRCA1/2 mutations and high-risk HER2-negative early breast cancer (Abstract GS4-09).

Michael Gnant, MD, of the Medical University of Vienna, discusses phase III findings from the PALLAS study, which showed that adding 2 years of palbociclib to ongoing adjuvant endocrine therapy did not improve survival for patients with stage II to III hormone receptor–positive, HER2-negative early breast cancer. Dr. Gnant also talks about whether any correlative studies hint at patient subgroups that this regimen may benefit (Abstract GS1-07) .

Sara A. Hurvitz, MD, of the University of California, Los Angeles Jonsson Comprehensive Cancer Center, discusses phase III findings from the DESTINY-Breast03 trial, which compared ado-trastuzumab deruxtecan (T-DXd) with standard-of-care trastuzumab emtansine (T-DM1) in patients with HER2-positive metastatic breast cancer. T-DXd showed superior progression-free survival across subgroups of patients previously treated with trastuzumab and a taxane, including those with brain metastases (Abstract GS3-01).

François-Clément Bidard, MD, PhD, of the Institut Curie, discusses phase III findings of the PADA-1 study, which showed that optimizing endocrine therapy after detecting the ESR1 mutation in patients with hormone receptor–positive, HER2-negative metastatic breast cancer may double their median progression-free survival (Abstract GS3-05).
