Peter Schmid, MD, PhD, on Early-Stage TNBC: Updated Survival Results From KEYNOTE-522
2023 SABCS
Peter Schmid, MD, PhD, of Queen Mary University of London and Barts Cancer Institute, discusses phase III findings from KEYNOTE-522 showing that neoadjuvant pembrolizumab plus chemotherapy followed by adjuvant pembrolizumab continues to show a clinically meaningful improvement in event-free survival compared with neoadjuvant chemotherapy alone in patients with early-stage triple-negative breast cancer (TNBC) (Abstract LBO1-01).

Eleftherios P. Mamounas, MD, of Orlando Health Cancer Institute, discusses primary outcomes from the NRG Oncology/NSABP B-51/RTOG 1304 study of locoregional irradiation in patients with biopsy-proven axillary node involvement at presentation who become pathologically node-negative after neoadjuvant chemotherapy (Abstract GS02-07).

Luca Gianni, MD, of Milan’s Fondazione Michelangelo, discusses findings from the APTneo Michelangelo trial, which showed that adding atezolizumab to chemotherapy and trastuzumab plus pertuzumab did not significantly increase the rate of pathologic complete response (pCR) in women with HER2-positive breast cancer. An exploratory analysis showed that adding atezolizumab to neoadjuvant anthracycline and cyclophosphamide followed by HPCT (trastuzumab + pertuzumab and chemotherapy) led to higher pCR rates than HPCT and atezolizumab (Abstract LBO1-02).

Sherene Loi, MD, PhD, of Australia’s Peter McCallum Cancer Centre, discusses an exploratory analysis of CheckMate 7FL which showed that patients with PD-L1–positive, high-risk, estrogen receptor–positive, HER2-negative primary breast cancer may achieve substantial pathologic complete response rates with the addition of nivolumab to neoadjuvant chemotherapy (Abstract GS01-01).

Aditya Bardia, MD, MPH, of Massachusetts General Hospital Cancer Center, discusses phase III findings from the KEYNOTE-756 study, which showed that adding pembrolizumab to chemotherapy increases the pathologic complete response rate and lowers the residual cancer burden in patients with early-stage, high-risk ER-positive or HER2-negative breast cancer (Abstract GS01-02).

Nicholas C. Turner, MD, PhD, of The Royal Marsden Hospital NHS Foundation Trust, and the Institute of Cancer Research, London, discusses the monarchE trial, which evaluated molecular profiling of archived primary tumor tissue from patients with hormone receptor–positive, HER2-negative, node-positive, high-risk early-stage breast cancer and its potential association with clinical outcomes. Adjuvant abemaciclib plus endocrine therapy (ET) maintained invasive disease–free survival benefit compared with ET alone across all molecular subtypes as measured by RNA sequencing (Abstract GS03-06).
