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).

Jonathan W. Goldman, MD, of the University of California, Los Angeles, presents event-free survival data from the primary analysis of the phase III LIBRETTO-432 trial, which investigated the efficacy of the kinase inhibitor selpercatinib in patients with stage IB–IIIA RET fusion–positive non–small cell lung cancer (NSCLC) (Abstract LBA3).

Noelle Cloven, MD, of Texas Oncology, discusses the actively recruiting RAINFOL-03 (ENGOT-EN-31/GOG-3128) study, a global, phase III, open-label, randomized study of rinatabart sesutecan vs investigator’s choice of chemotherapy in patients with endometrial cancer after receipt of platinum-based chemotherapy and PD-L1 inhibition (Abstract TPS5646).

Misty Dawn Shields, MD, PhD, of Indiana University Melvin and Bren Simon Comprehensive Cancer Center, shares her perspective on two small cell lung cancer (SCLC) abstracts presented at this year’s meeting. The first focuses on a post hoc analysis of the phase III DeLLphi-304 trial (Abstract 8006), which looked at the intracranial efficacy of tarlatamab in the second line; the second evaluated concurrent thoracic radiotherapy, chemotherapy, and durvalumab in extensive-stage disease (Abstract LBA8005).

Mark A. Dickson, MD, of Memorial Sloan Kettering Cancer Center, presents findings from SARC041, a phase III randomized double-blind study of abemaciclib vs placebo in patients with dedifferentiated liposarcoma; patients who received abemaciclib experienced a statistically significant improvement in progression-free survival (Abstract LBA2).

Supriya Gupta, MD, of the University of Minnesota, presents data on azercabtagene zapreleucel, an investigational anti-CD19 allogeneic chimeric antigen receptor (CAR) T-cell therapy, in combination with low-dose interleukin-2 in patients with relapsed or refractory non-Hodgkin lymphoma (NHL) and chronic lymphocytic leukemia (CLL) (Abstract 7012).
