Perioperative durvalumab plus fluorouracil, leucovorin, oxaliplatin, and docetaxel for resectable gastric and gastro-oesophageal junction adenocarcinoma (MATTERHORN): final results of overall survival and event-free survival by pathological response in a global, randomised, double-blind, placebo-controlled, multicentre, phase 3 trial

Listen to this summary

The authors of the MATTERHORN trial aimed to evaluate the impact of perioperative durvalumab combined with fluorouracil, leucovorin, oxaliplatin, and docetaxel (FLOT) on overall survival in patients with resectable gastric and gastro-oesophageal junction adenocarcinoma. The study found that overall survival significantly improved in the durvalumab group compared to the placebo group, establishing durvalumab plus FLOT as a new standard treatment option for this patient population.
