ABSTRACT: Introduction: Gastrointestinal stromal tumor (GIST) is the most common non-epithelial, mesenchymal tumor of the digestive tract. Targeted therapy has improved the prognosis but the diagnosis must be accurate before using the existing drugs. Aim: To report the diagnostic difficulty in our context through the clinical polymorphism and define the position of targeted therapy in the management of GIST metastatic stomach. Casuistry: We report 3 cases of gastric GIST with liver metastasis in different circumstances of discovery. Patients were 21, 45, and 73 years old. Discovery circumstances were respectively digestive hemorrhage, severe clinical anemia, abdominal tumor and gastric tumor. There was hepatic metastasis in the three cases. The three patients received Imatinib treatment, adjuvant treatment for the first two cases, and neo-adjuvant treatment for the third case, with a very good clinical response and CT response on metastases. Conclusion: Because of their rarity, GISTs are often difficult to diagnose, and necessarily require immunohistochemistry which is not available in our work context. The effectiveness of targeted therapy even on metastasis needs a rigorous diagnostic approach to improve patient survival.
