Paolo Tarantino, MD, PhD, on HER2-Positive Metastatic Breast Cancer: Overall Survival by Genomic Profile
ASCO 2026
Paolo Tarantino, MD, PhD, of Dana-Farber Cancer Institute, reviews the results of a large clinicogenomic database study that looked at overall survival by genomic profile among patients with HER2-positive metastatic breast cancer. Patients with mutations in key DNA repair genes experienced a numerically worse prognosis, representing an unmet need for drug development, say researchers (Abstract 1045).
Suneel Kamath, MD, of Cleveland Clinic, discusses a study that found tissue tumor mutation burden (TMB) was a stronger predictor of immunotherapy outcomes than blood-based circulating tumor DNA testing, with high tissue TMB associated with a longer time to treatment failure (Abstract 2580).
Daneng Li, MD, of City of Hope, discusses dose-finding results from a phase I/II trial of tegavivint, a downstream Wnt/β-catenin inhibitor, in patients with advanced hepatocellular carcinoma (HCC) (Abstract 4015).
Lucy Gilbert, MD, of McGill University Health Centre, discusses subgroup analyses from the ROSELLA study. Relacorilant plus nab-paclitaxel demonstrated a statistically and clinically significant overall survival benefit in patients with platinum-resistant ovarian cancer compared to a weekly taxane; subgroup analyses for overall survival showed a consistent benefit favoring the addition of relacorilant to nab-paclitaxel irrespective of prior taxane use (Abstract 5503).
Laura Alder, MD, of Duke University Medical Center, highlights emerging data discussed in the meeting’s oral abstract session on small cell lung cancer, including increased toxicity without efficacy benefit from concurrent chemoradiation and immunotherapy, the intracranial activity of tarlatamab-dlle, and early data for a SEZ6-targeting antibody-drug conjugate.

Atish Choudhury, MD, PhD, of Dana-Farber Cancer Institute, talks about findings from the phase II A-DREAM/Alliance A032101 trial, which explored the possibility of androgen-deprivation (ADT) interruption in patients with metastatic hormone-sensitive prostate cancer who had an exceptional response to androgen receptor pathway inhibitors (ARPIs) (Abstract 5004).
