Gabriel N. Hortobagyi, MD, on Early Breast Cancer: Final Invasive Disease–Free Analysis From the NATALEE Trial
2023 SABCS
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).

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).

Seema Khan, MD, of Northwestern University and the Robert H. Lurie Comprehensive Cancer Center, discusses the 5-year clinical outcomes of ECOG-ACRIN 4112, a prospective trial that supports the omission of radiotherapy after surgery in patients with ductal carcinoma in situ who have a low DCIS score and its use in patients with intermediate/high DCIS scores (Abstract GS03-01).

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).

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).

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).
