Abstract:
Objective To investigate the significance of the mutation of c-kit gene in the development,(clinical) pathology and prognosis of gastrointestinal stromal tumors(GISTs).Methods The technique of(PCR-SSCP) was used to detect ckit gene mutation in 106 cases of GIST,and 57 of the cases were(followed-up).Results The c-kit gene mutation rate in the whole group was 45.3%(48/106),and(3.4)%(2/41) in benign GIST,and 70.8%(46/65) in malignant GIST.The 1-,3 and 5-year survival rates and median survival time of the mutation positive group were all markedlly lower than those of the(mutation) negative group.A comparison of the parameters that can differentiate the benign GISTs from malignant ones such as size,histological necrosis,aggressive grade,nucleus mitotic count and nuclear discrepancy,showed significant difference between the of postive and negative gene mutation(P
