ABSTRACT

Objective To investigate the diagnosis and treatment of gastric stromal tumor(GST). Methods Retrospective analysis was made on the clinical data of 18 cases of GST. The diagnosis of 18 cases was confirmed by pathology. Local resection of the tumor was performed in 2 cases,partial gastrectomy in 5 cases, subtotal gastrectomy in 9 cases, and total gastrectomy with lymph node clearance in 2 cases. Results Most of the patients were over forty years old.In 55.5% of cases,the location of tumor was at the middle of the stomach,and 61.0% of cases were intragastric growth type.The preoperative diagnostic rate was 27.8%,misdiagnostic rate was 72.2%.The resectability rate was 100%. No postoperative complications and operative death occurred in this series. Fifteen cases were followed up for 1 to 10 years. During follow up,2 cases died of recurrence of the tumor, and the other patients were still alive. Conclusion The GST patients lack typical clinical manifestations, and the preoperative diagnosis is difficult.Barium meal examination and gastroscopy are the main supplementary examinations.A combination of histological and immunohistochemical examinations is helpful to confirm the diagnosis.Surgical resection is the only effective therapeutic method.
