Metastatic gastrointestinal stromal tumor with long-term response after treatment with concomitant radiotherapy and imatinib mesylate.
Total surgical excision of the tumor is considered to be the only hope in treatment of malignant mesenchymal tumors. The roles of radiotherapy and/or chemotherapy have not yet been established. We report here a case of metastatic gastrointestinal stromal tumors with a dramatic long duration of response after treatment with concurrent radiotherapy and imatinib mesylate. The patient had a long-term complete response at the radiotherapy region with concomitant imatinib therapy although previous metastatic sides persisted with partial response.
