This is a phase III, multicenter, prospective, randomized, controlled clinical trial to evaluate the impact of omentectomy for advanced gastric cancer on patient survival.


In order to evaluate the impact of omentectomy for advanced gastric cancer on patient survival, we designed this trial. Patients who received curative gastrectomy were divided into two groups based on whether they underwent omentectomy. The purpose of this study is to prove the non-inferiority of omentum preservation compared with omentectomy in patients with T3-T4a gastric cancer.
