Jame Abraham, MD, FACP, on Update on the DESTINY-Breast05 Trial
ASCO 2026
Jame Abraham, MD, FACP, of Cleveland Clinic, provides an update on the DESTINY-Breast05 trial, which is an ongoing phase III trial investigating postneoadjuvant trastuzumab deruxtecan (T-DXd) as compared with trastuzumab emtansine (T-DM1) in patients with HER2-positive breast cancer with residual invasive disease and node-positive disease at surgery or inoperable disease at diagnosis. Dr. Abraham makes special note of rates of interstitial lung disease seen in the trial and methods of management.

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).

Elizabeth McDonald, MD, PhD, of the University of Pennsylvania, discusses results from a retrospective cohort study that showed that the use of GLP-1 treatment was associated with a significantly lower incidence of breast cancer, after accounting for age, race, ethnicity, BMI, breast density, and type 2 diabetes status (Abstract 10506).
Jamie E. Chaft, MD, FASCO, of Memorial Sloan Kettering Cancer Center, discusses findings from ECOG-ACRIN EA5142/ALCHEMIST, a phase III randomized trial that evaluated the efficacy of adjuvant nivolumab after standard-of-care adjuvant therapy in patients with resected lung adenocarcinoma without sensitizing EGFR and ALK alterations and squamous cell carcinoma (Abstract 8000).
Walter Weber, MD, of University Hospital Basel, presents data from the international randomized phase III PREPEC trial (OPBC-02), which found prepectoral implant-based breast reconstruction (IBBR) significantly and relevantly improved long-term quality of life—at the cost of a higher risk of loss or replacement of expander or implant—compared to subpectoral IBBR (Abstract 504).

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).
