ABSTRACT
AIM: In this article, gastrointestinal tumor-related historical archives of pathology in our hospital were reviewed in order to acknowledge gastrointestinal stromal tumors (GIST). METHODS: These cases were rediagnosed correctly , these tissues were labeled with some antibodies such as CD117, CD34, ?-SMA, S-100, and their clinical characteristics were explored. RESULTS: CD117, CD34 were expressed widely in GISTs ,the percentage of positive expression was CD117 (50/56, 89.3%), CD34 (37/56, 66.1%), respectively, ?-SMA, S-100 were (17/56, 30.4%), (4/56, 7.1%), respectively, desmin was negative in these cases. Among them, 29 cases were benign and borderline, 27 cases were malignant. The percentage of occurring in stomach and intestine was 91.1%. CONCLUSION: CD117, CD34 are expressed significantly in GIST, these might be assistant markers for GIST diagnosis. GISTs mostly occurred in stomach and intestine.
