Abstract:

Background and Design.- At a curative resectional procedure in for cases of gastric cancer, a matter of great import is boundaries of the invading process extending to the oral and/or anal directions. Failure to appreciate this fact during gastrectomy leads to transection in an area invaded by the tumor. Resection-line involvement has been shown to have a causing effect on both anastomatic leakage and perioperative mortality. It also predisposes to anastomotic recurrence and long-term survival rate is impaired. Prognostic impact of resection-line involvement was investigated in patients undergoing potentially curative gastrectomy. Information collected from medical and pathological records included the age and gender of patients, location of tumor, histology type histologic grade, macroscopic type, regional lymph node metastasis and residual tumor in resectional lines. A positive margin was defined as disease present at the line of luminal transection in the mucosa, submucosa and/or serosa.
