摘要: Purpose Gastrointestinal stromal tumors (GISTs) are mesenchymal of the gastrointestinal tract. Most (80 %) contain activating mutations in KIT receptor tyrosine kinase, roughly 10 % platelet-derived growth factor receptor-alpha (PDGFRA). In a small subset, BRAF an alternative molecular pathway. GISTs respond well to imatinib, but low response is seen patients with wild-type or PDGFRA. Resistance has also been reported as result downstream effectors such BRAF.
