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).

Jana de Boniface, MD, PhD, of Capio Saint Göran's Hospital and Karolinska Institutet, reviews overall survival and patient-reported arm morbidity findings from the SENOMAC trial, which sought to determine if patients with breast cancer and sentinel lymph node macrometastases could omit complete axillary dissection (Abstract LBA503).
Elizabeth Smyth, MD, of Oxford NIHR Biomedical Research Centre, Churchill Hospital, discusses three major studies presented at this year’s meeting: the antibody-drug conjugate izalontamab brengitecan in recurrent or metasatic esophageal squamous cell carcinoma (Abstract 4008); the ATTRACTION-6 study of chemoimmunotherapy in HER2-negative advanced gastric/gastroesophageal junction (GEJ) cancer (Abstract 4006); and an investigational EP4 antagonist in combination with chemoimmunotherapy as a first-line strategy for HER2-negative gastric/GEJ cancer (Abstract 4007).

Shubham Pant, MD, MBBS, of The University of Texas MD Anderson Cancer Center, discusses the practice-changing results of the phase III RASolute 302 study, which showed that daraxonrasib doubled median overall survival compared with standard chemotherapy in pretreated metastatic pancreatic cancer (Abstract LBA5).
