Reshma Jagsi, MD, DPhil, on Early-Stage Breast Cancer: 5-Year Outcomes With Endocrine Therapy and Breast-Conserving Surgery
2023 SABCS
Reshma Jagsi, MD, DPhil, of Emory University Winship Cancer Institute, discusses the IDEA trial of endocrine therapy without radiotherapy after breast-conserving surgery for postmenopausal patients between the ages of 50 and 69 with stage I breast cancer. The regimen demonstrated a low risk of relapse in this population, with a genomic assay used in combination with classic clinical and biological features for treatment selection (Abstract GS02-08).

Daniel G. Stover, MD, of The Ohio State University Comprehensive Cancer Center, discusses a biomarker analysis from the PALLAS adjuvant trial, which compared 2 years of the CDK4/6 inhibitor palbociclib with endocrine therapy vs endocrine therapy alone, as adjuvant treatment for patients with stage II–III hormone receptor–positive, HER2-negative breast cancer. The genomic subtype PAM50 was defined in the protocol of the PALLAS trial as the primary biomarker for analysis of prediction and prognosis (Abstract GS03-07).

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).

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).

Senthil Damodaran, MD, PhD, of The University of Texas MD Anderson Cancer Center, discusses final results from the FOENIX-MBC2 study of the efficacy and safety of futibatinib in patients with locally advanced or metastatic hormone receptor–positive, HER2-negative breast cancer harboring high-level FGFR1 gene amplification. Futibatinib plus fulvestrant showed antitumor activity in those whose disease had progressed on prior CDK4/6 inhibitors (Abstract RF01-04).

Hope S. Rugo, MD, of the University of California, San Francisco Helen Diller Family Comprehensive Cancer Center, discusses patient-reported outcomes from the phase III CAPItello-291 study; the trial centered on adding capivasertib to fulvestrant in patients with aromatase inhibitor–resistant, hormone receptor–positive, HER2-negative advanced breast cancer. Patients treated with capivasertib and fulvestrant reported maintained health-related quality of life longer than those treated with placebo and fulvestrant (Abstract PS02-02).
