Abstract
Gastrointestinal stromal tumors (GISTs) are a group of rare gastrointestinal neoplasms of mesenchymal origin. Mutations in the C-KIT or PDGFRA genes are key mechanisms for tumor development. The identification of these pathogenetic mechanisms, as well as significant progress in understanding the molecular biology of gastrointestinal stromal tumors, have led to the development of a personalized approach to the treatment of GISTs, which has had a significant impact on improving patient treatment outcomes.
