Objective To study the diagnosis and treatment of synchronous gastric cancer and gastric stromal tumor in 18 cases. Methods Clinical data of 18 cases of synchronous occurrence of gastric cancer and gastric stromal tumor from January 1996 to December 2009 were analyzed retrospectively.Results Clinical features of all cases were atypical. There was 1 case diagnosed preoperatively, 3 cases diagnosed intraoperatively and 14 cases diagnosed postoperatively. The mean size of gastric cancer and gastric stromal tumor was (3.3±2.3) cm and (0.9 ±0.5) cm respectively. There were 16 cases of gastric stromal tumor in low risk of malignance and 2 cases in moderate risk of malignance. All cases were operated without complications and the 1-year, 3-year and 5-year overall survival rate was 88.2%, 63.2% and 36. 1% respectively. Conclusions Clinical features of synchronous occurrence of gastric cancer and gastric stromal tumor are atypical, in this series most gastric stromal tumors are in early stage and of low risk of malignance. The prognosis of patients with synchronous occurrence of gastric cancer and gastric stromal tumor mainly depends on gastric cancer.
