284 рatients with resectable (T1b-4 and/or N-/+, M0) adenocarcinoma of the stomach or the esophagogastric junction without previous therapy will be included in this study. After laparocopic staging patients will be randomized to receive preoperatively 4 cycles FLOT or 4 cycles XELOX followed by surgery. Subsequently another 4 cycles of FLOT or 4 cycles XELOX are applicated. Primary endpoint is histopathological regression rate, secondary endpoints are disease-free survival, perioperative morbidity and mortality, correlation between pathological responce and disease-free survival.
Patients with resectable adenocarcinoma of the stomach or the esophagogastric junction 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 Oxaliplatin and Capecitabin (XELOX).
