A case of gastric cancer with a synchronous hepatic metastasis responding to postoperative oral administration of UFT and intermittent intrahepatic arterial chemotherapy of 5-FU

摘要

A 65-year-old male was admitted to our hospital because of sudden onset of upper abdominal pain due to the perforation of gastric cancer with synchronous hepatic metastasis. He underwent total gastrectomy with lymphatic dissection of D1 + alpha. Pathological diagnosis of the surgical specimen was moderately differentiated tubular adenocarcinoma. The cancer progression was fStage IV (T1, N0, H1, P0). Since 50 days after surgery, he had received oral administration of UFT (300-600 mg/day) and intermittent intrahepatic arterial infusion of 5-FU (one injection, 500 mg/2 weeks). Seven months after the start of chemotherapy, the size of hepatic lesion was reduced. Thirteen months later, the tumor became necrotic with cystic change. Furthermore, 22 months later, abdominal CT scan showed complete response. He has been well without recurrence for 38 months following the start of chemotherapy.
