Gastrointestinal stromal tumors (GISTs) develop within the digestive tract and harbor functional mutations of KIT (v-kit Hardy-Zuckerman 4 feline sarcoma viral oncogene homolog) and PDGFRA (platelet-derived growth factor receptor-α) that primarily drive the tumor growth and progression [1, 2]. This evidence concerns the gene KIT and gastrointestinal stromal tumor.
