Abstract: Gastrointestinal stromal tumor(GIST)is the most common tumor of archenteric mesenchymal tissue.About 10% of patients are diagnosed as GIST morphologically and immunohistochemically without KIT and PDGFRA gene mutations which is defined wild-type GIST.According to the absence of succinate dehydrogenase B(SDHB)expression,wild-type GIST can be divided into SDH-deficient and non-SDH-deficient types.SDH-deficient types include syndrome-free associated,Carney triad associated,and Carney-stratakis synthesis associated GIST;non-SDH-deficient types include BRAF mutations,type I neurofibromatosis-related,K/N-RAS mutations,and quadruple wild-type GIST.The occurrence,development,clinicopathological features and treatment principles of wild-type GIST are significantly different from those of KIT or PDGFRA mutant GIST.This article reviews the molecular mechanism and clinical progress of wild-type GIST.
