2026 ASCO GI
Elizabeth Smyth, MD, of the Oxford NIHR Biomedical Research Centre, Churchill Hospital, presents findings from an analysis of the MATTERHORN trial, a phase III study that examined fluorouracil, leucovorin, oxaliplatin, and docetaxel (FLOT) plus durvalumab in patients with resectable gastric/gastroesophageal junction cancer. Dr. Smyth discusses rates of FLOT discontinuation along with event-free survival based on FLOT completion status in the trial (Abstract 343).

Elena Elimova, MD, of Princess Margaret Cancer Centre, presents findings from the primary analysis of the phase III HERIZON-GEA-01 trial, which evaluated zanidatamab, a dual HER2-targeted bispecific antibody, plus chemotherapy with or without the PD-1 inhibitor tislelizumab vs trastuzumab plus chemotherapy as first line-regimens for HER2-positive locally advanced, unresectable, or metastatic gastroesophageal adenocarcinoma (Abstract LBA285).

Matthew Strickland, MD, of Massachusetts General Hospital, reviews results from the phase IIb TERRIFIC trial, which compared the efficacy and safety of the PD-1 inhibitor tislelizumab plus chemoradiotherapy vs chemoradiotherapy or chemotherapy alone in the neoadjuvant treatment of patients with gastric or gastroesophageal junction adenocarcinoma (Abstract 286).

Daniela Molena, MD, of Memorial Sloan Kettering Cancer Center, discusses a comparison of the surgical journeys of patients with resectable gastric/gastroesophageal adenocarcinoma who either received fluorouracil, leucovorin, oxaliplatin, and docetaxel (FLOT) plus durvalumab or FLOT plus placebo in the MATTERHORN study (Abstract 353).
