Abstract:
The clinical data of 22 cases with gastrointestinal stromal tumors were retrospectively analized.The main clinical manifestations were gastrointestinal bleeding (14/22),abdominal discomfort (5/22) and abdominal lump (3/22),stomach was the most common site of the tumor (14/22).All 22 cases underwent surgical treatment and pathological examination confirmed that 12 cases were benign.Immunohistochemical results showed that 68% cases were negative in solubility acid protein-100 (S-100),and the positive rates of tyrosine-protein kinase acceptor 117 (CD117),hemopoietic stem cell antigen 34 (CD34) and negative rate of smooth muscle actin (SMA) were all 73%.Eighteen cases were followed up for 1-5 years after operation,among them 3 died.The survival was closely related to the size,the pathological characteristics and the recurrance of the tumor as demonstrated by multivariate Cox regression analysis.Since gastrointestinal stromal tumor has no specific clinical manifestations,preoperative diagnosis is difficulty,so surgical resection and subsequent pathological examination is used for confirmation of diagnosis,as well as treatment of the disease.
