Abstract:
Gastrointestinal stromal tumor( CIST) is the most common form of mesenchymal tumor of the gastrointestinal tract. Most GISTs characteristically harbor activating mutations of c-kit or PDCFRA( platelet derived growth factor receptor alpha, PDGFRA). All CISTs should be regarded having malignant potential. Tumor size and mitotic count, as two basic progonstic factors for primary CISTs, are largely site dependent. Most c-kit mutations have been found in exon 11,9,13,17 while PDGFRA mutations re found in exon 18,12,14.The sites and types of mutions are associated with the prognosis of CIST. Histopathology and immunohistochem-istry are another two factors predicting tumor outcome.
