Suneel Kamath, MD, on Correlation Between Blood and Tissue Tumor Mutation Burden
ASCO 2026
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).
Joel W. Neal, MD, PhD, of Stanford Cancer Institute, discusses updated overall survival data from cohort C of the CHRYSALIS-2 trial, which looked at first-line amivantamab plus lazertinib in previously untreated patients with atypical EGFR-mutated advanced non–small cell lung cancer (NSCLC) (Abstract 8501).

Erika P. Hamilton, MD, FASCO, of Sarah Cannon Research Institute, talks about a comparison of the efficacy and safety of tucatinib vs placebo combined with trastuzumab and pertuzumab as maintenance therapy for HER2-positive metastatic breast cancer by stratified subgroups (Abstract 1005).
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).

John V. Heymach, MD, PhD, of The University of Texas MD Anderson Cancer Center, discusses results from the primary analysis of the multinational phase III WU-KONG28 trial, which looked at sunvozertinib monotherapy vs platinum-based therapy as first-line treatment for patients with advanced non–small cell lung cancer (NSCLC) and EGFR exon 20 insertions (Abstract LBA8500).

Marlana M. Orloff, MD, of Thomas Jefferson University Hospital, reviews primary results from the OptimUM-02 trial, which investigated the doublet of darovasertib plus crizotinib vs investgator’s choice for first-line therapy among patients with HLA-A2–negative metastatic uveal melanoma (Abstract LBA9503).
