folfirinox vs flot chemotherapy for resectable gastric or esophagogastric junction adenocarcinoma

Conditions: Stomach Neoplasms; Gastrointestinal Neoplasms; Docetaxel; Oxaliplatin; Fluoruracil; Irinotecan Hydrochloride

Summary: patients with resectable adenocarcinoma of the stomach or the esophagogastric junction (ii-iii type by siewert) without previous therapy will be treated with one of two chemotherapy combinations before and after surgery. one half of the patients gets 5-fluorouracil (5-fu), leucovorin, oxaliplatin and docetaxel (flot), the others 5-fluorouracil (5-fu), leucovorin, oxaliplatin and irinotecan (folfirinox). main objective of the study is median overall survival.

538 patients with resectable (ct4cn0 or ct1-4 and cn+, cm0) adenocarcinoma of the stomach or the esophagogastric junction without previous therapy will be included in this study. after randomization patients receive perioperatively 4 cycles flot or folfirinox, followed by a restaging of the tumour status and surgery. subsequently another 4 cycles of flot or folfirnox are applicated.
