Robert C. Stein, PhD, MBBChir, FRCP, on ER-Positive HER2-Negative Early Breast Cancer: Test-Directed Chemotherapy
ASCO 2026
Robert C. Stein, PhD, MBBChir, FRCP, of the National Institute for Health Research University College London Hospitals Biomedical Research Centre, discusses the first results from the phase III randomized OPTIMA trial, which is comparing chemotherapy decisions made with the Prosigna (PAM50) gene expression test with standard treatment with estrogen receptor (ER)-positive, HER2-negative early breast cancer (Abstract 500).
Gopa Iyer, MD, of Memorial Sloan Kettering Cancer Center, presents initial results from the phase I NEXUS-01 study, which evaluated LY4052031, an antibody-drug conjugate targeting Nectin-4, in patients with advanced or metastatic urothelial carcinoma (Abstract 4508).

Kevin Kalinsky, MD, MS, FASCO, of Winship Cancer Institute of Emory University, provides an update focusing on progression-free survival after next line of treatment and subsequent therapies among patients enrolled in the ASCENT-04 trial. The study compared sacituzumab govitecan plus pembrolizumab vs chemotherapy plus pembrolizumab in patients with previously untreated PD-L1–positive metastatic triple-negative breast cancer (Abstract LBA1000).

Mali Barbi, MD, MS, of Northwell Health Cancer Institute Center for Women's Cancer, discusses durable survival benefits shown in the NRG-GY018 trial with pembrolizumab and the RUBY trial with dostarlimab for patients with mismatch repair–deficient (dMMR) endometrial cancer. In addition, B7-H4 antibody-drug conjugates such as puxitatug samrotecan are emerging as options for relapsed/metastatic disease.

Ramez N. Eskander, MD, of UC San Diego Moores Cancer Center, presents an updated overall survival analysis and examination of subsequent therapy in patients with endometrial cancer treated with pembrolizumab plus carboplatin/paclitaxel as compared to carboplatin/paclitaxel plus placebo in the NRG-GY018 trial (Abstract 5502).

Danny Rischin, MD, of Peter MacCallum Cancer Centre, talks about data from the disease-free survival analyses of the C-POST study, which were conducted per high-risk criteria and start time after radiotherapy. C-POST evaluated adjuvant cemiplimab-rwlc for patients with high-risk cutaneous squamous cell carcinoma (CSCC) (Abstract 6083).
