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).

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).
The ASCO Post Staff
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).
The ASCO Post Staff
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).

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).

Barbara Pistilli, MD, of France’s Gustave Roussy, discusses a phase Ib analysis from the CAPItello-292 study, which showed capivasertib plus palbociclib plus fulvestrant was tolerable at all dose levels in heavily pretreated patients with hormone receptor–positive, HER2-negative advanced breast cancer. As data collection continues, evidence of clinical activity has been observed in patients treated with the recommended phase III dose (Abstract PS12-09).
