Surgical management of gastric stump cancer:a report of 37 cases

Objective:To observe the clinicopathological characteristics of gastric stump cancer(GSC)and evaluate the benefitsof radical surgery of GSC.Methods:The clinicopathological characteristics and postoperative survival time of 37 GSC patientswho underwent surgery were investigated retrospectively.The survival time was compared according to the type of surgicaloperation(radical resection vs palliative operation).Twenty-one cases that received radical resection were analyzed based on thepTMN stage.Survival curves were traced by using Kaplan-Meier methods.Results:Most GSC(32/37)was detected in patientswho had received Billroth Ⅱ reconstruction after partial gastrectomy for benign gastric disease.The lesser curvature side and thesuture line of anastomosis were the most frequent sites where GSC occurred(27/37).Differentiated adenocarcinoma was thedominant histopathological type(24/37).The postoperative 5-year survival rate of early stage GSC patients(n=9)was significantlyhigher than advanced stage GSC(n=12)(55.6
