Is bursectomy necessary for patients with gastric cancer invading the serosa?
GROUND/AIMS: To confirm the impact of bursectomy on survival, we reviewed the clinical records of patients who underwent radical total gastrectomy with bursectomy for gastric cancer invading the serosa, with special reference to the location of tumor invasion. METHODOLOGY: From the records, patients were selected for this retrospective cohort study according to the following criteria: (a) Invasion beyond the serosal surface, (b) No metastases to liver, peritoneum, or distant organs, (c) Negative for peritoneal lavage cytology, and (d) Patients underwent curative D2 total gastrectomy with complete omental bursectomy. A total of 134 patients were eligible. These patients were divided into a group I which included patients with tumors that invaded only the posterior wall and a group II which included those with others. Survival was examined by uni- and multivariate analyses. RESULTS: Survival rates at 3 and 5 years were 67.3% and 53.0% for group I and 68.8% and 53.8% for group II. There w
