Abstract excerpt

AIM: To investigate the incidence of KIT immunohistochemical staining in (GI) stromal tumors (GISTs), and to analyze the clinical manifestations of the tumors and prognostic indicators. METHODS: We retrospectively analyzed 50 cases of previously diagnosed GISTs. Tissue samples were assessed with KIT (CD117 antigen), CD34, SMA, desmin, S-100, NSE, PCNA, Ki-67, and BCL-2 for immunohistochemical study and...
