title: Giant Gastric Gastrointestinal Stromal Tumor (GIST).
abstract: Gastrointestinal stromal tumors (GIST) represent 0.1-3 % of gastrointestinal malignancy. Surgery is the mainstay of treatment, but in high-risk tumors, imatinib can help to achieve better oncological outcomes. We present a rare case of a patient with gastric GIST with very aggressive evolution in a short period of time despite the use of neoadjuvant therapy with imatinib.
