Gastrointestinal stromal tumors is a research domain focused on a distinct category of mesenchymal neoplasms predominantly located within the gastrointestinal tract. This field investigates their cellular origin from interstitial cells of Cajal or related progenitors, their characteristic molecular pathology, notably activating mutations in the *KIT* or *PDGFRA* genes, and aims to elucidate mechanisms for diagnosis, prognosis, and targeted therapeutic intervention.
