Daniel G. Stover, MD, on Early-Stage Breast Cancer: A Biomarker Analysis From the PALLAS Trial
2023 SABCS
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).

Gabriel N. Hortobagyi, MD, of The University of Texas MD Anderson Cancer Center, discusses findings from the NATALEE trial, which continued to demonstrate improved invasive disease–free survival with ribociclib plus a nonsteroidal aromatase inhibitor (NSAI) over a NSAI alone in patients with hormone receptor–positive, HER2-negative early breast cancer (Abstract GS03-03).

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).

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).

Oleg Gluz, MD, of the West German Study Group and Breast Center Niederrhein, discusses the impact of age and ovarian function suppression in response to preoperative endocrine treatment for both pre- and postmenopausal patients with early-stage breast cancer. He describes ways in which the outcome data of the ADAPTcycle study might influence clinical decisions (Abstract LBO1-05).
Aditya Bardia, MD, MPH, of Massachusetts General Hospital Cancer Center, discusses updated phase III results from the TROPION-Breast01 study. The data showed an improvement in progression-free survival with datopotamab deruxtecan compared with investigator’s choice of chemotherapy across all subgroups of patients with inoperable or metastatic hormone receptor–positive, HER2-negative breast cancer who have received one to two prior lines of chemotherapy (Abstract GS02-01).
