Summary
Brief summary (as posted)
The main goal of this study is to investigate the proportion of participants with locally advanced gastric and gastroesophageal adenocarcinoma without previous treatment during the last 5 years who can tolerate all planned cycles of chemotherapy and radical surgical treatment who will be prospectively randomized into two groups to undergo one of two chemotherapy regimens, followed by surgery: 1. 8 cycles of Total Neoadjuvant ChemoTherapy (TNT) with 5-Fluorouracil (5-FU), Leucovorin, Oxaliplatin, and Docetaxel (FLOT) followed by surgery. 2. 4 cycles of Neoadjuvant FLOT chemotherapy scheme preoperatively and 4 adjuvant FLOT cycles postoperatively.
