A case of gastrointestinal stromal tumor (GIST) successfully treated with resection after a long-term control medication by molecular targeted drugs]

We report a case of GIST successfully treated with resection after a long-term control medication by molecular targeted drugs. A 59-year-old man underwent an un-complete resection for multiple abdominal tumors. The patient was treated with imatinib at a dose of 400 mg/day for high risk GIST. Since he had PD 22 months after the treatment, sunitinib was administered at a dose of 50 mg/day. However, abdominal tumor grew, and melena and intra-abdominal hemorrhage were appeared. After 27 months from the first treatment, a resection of tumors was performed to control abdominal hemorrhage. After the operation, abdominal tumor was successfully controlled with the treatment of imatinib.
