Objective  To investigate the clinical characteristics, diagnosis, and treatment of gastric stromal tumor.
Methods  Clinical data of 217 patients with gastric stromal tumor from October 2007 to July 2011 were analyzed.
Results  The main clinical manifestation were abdominal pain, abdominal distension, bloody stools, abdominal mass, and so on. The tumour located at cardiac part, fundus of stomach, body of stomach, and pylorus part was 24 cases (11.0%), 103 cases (47.5%), 59 cases (27.2%), and 31 cases (14.3%), respectively. All the 217 patients underwent endoscopic or surgical resection and diagnosed by pathology and immunohistochemistry. The patients of high-low risk, low risk, intermediate risk, and high risk was 56 cases (25.8%), 67 cases (30.9%), 41 cases (18.9%), and 53 cases (24.4%), respectively. One hundred and forty patients were followed-up for 7-52 months (average 35 months). Thirty-five patients of high risk were investigated about the drug treatment after the first operation:19 cases were treated by using imatinib (tumor progressed in 2 cases) and 16 patients were not (tumor progressed in 9 patients). The rate of progression of patients treated by imatinib was significantly lower than another group (χ2=8.426, P=0.004). In 11 patients with tumor progressed, tumor recurrnce in 4 cases, tumor recurrence with diffused abdominal cavity metastasis in 1 case, tumor metastasized to humerus in 1 case, metastasized to liver and abdominal cavity in 1 case, and metastasized to liver in 4 cases.
Conclusions  Gastric stormal tumor is lack of specific clinical manifestations. Complete excision of the tumor is the main therapy method, and imatinib can improve prognosis.
