Abstract excerpt
AIM: To investigate the significance of c-kit gene mutation in gastrointestinal stromal tumors (GIST). METHODS: Fifty two cases of GIST and 28 cases of other tumors were examined. DNA samples were extracted from paraffin sections and fresh blocks. Exons 11, 9 and 13 of the c-kit gene were amplified by PCR and sequenced. RESULTS: Mutations of exon 11 were found in 14 of 25 malignant GISTs (56%), mutations of exon...
