[A case of leiomyosarcoma of the stomach treated effectively by tegafur and absolute curative resection]

A 51-year-old woman with leiomyosarcoma of the stomach treated effectively with FT 600 mg/day p.o., is reported. Leiomyosarcoma of the stomach was found in the greater curvature on the fornix by examinations involving X-ray and gastrofiberscopy with biopsy. She was subsequently treated with MMC 6 mg/2 alpha/w x 5 weeks and FT 600 mg/day continuously on account of liver metastasis determined by liver scintigram and CT. After one year, both gastrofiberscopy and X-ray pictures showed a decrease in the size of the SMT. An evaluation of the treatment showed partial response (PR), and the state of PR was maintained for more than 5 years. Six years and 9 months after chemotherapy, however, unresponsiveness to the therapy appeared and regrowth of the SMT followed. Furthermore, intrahepatic SOL was definitely diagnosed to be cavernous hemangioma of the liver. Consequently, proximal gastrectomy was performed using R1-absolute curative resection, after confirming that the histology of the SMT was leiomyosarcoma of the stomach by endoscopic partial tumorectomy.
