 The primary therapeutic choice for advanced, metastatic and/or recurrent gastrointestinal stromal tumor(GIST)is an oral intake of 400 mg/day imatinib mesylate. Advanced GIST has shown good responses to imatinib(response rate:40~60%;disease control rate:more than 80%). Responses to imatinib are considered to be well reflected by FDG-PET negativity and decrease in CT density after imatinib therapy. Progression free survival of patients with advanced GIST is improved to 2 years and overall survival 5 years. Imatinib-resistant GIST, however, is increasing as imatinib therapy is prolonged. Multidisciplinary treatment modality combined with surgery and molecular target agents is expected to overcome these phenomena.
