Gastrointestinal Stromal Tumors Short Review on KIT/PDGFRA Gene Mutations and Molecular Therapy

Ruihua Xie

Gastrointestinal stromal tumors (GISTs) are most frequent mesenchimal neoplasms of the gastrointestinal tract. Current knowledge demonstrates that the KIT and PDGFRA gene mutations play a central part in the pathogenesis. Mutations can be subdivided into primary and secondary mutations. Secondary mutations usually occur in KIT kinase domains after tyrosine kinase inhibitors treatment resulting in resistance to drugs. Besides surgery, therapy with tyrosine kinase inhibitors has led to develop novel treatments for patients now. However, secondary resistance has become a significant concern, illustrating the need to increase collaboration between surgical management and molecular therapy.
