[Effective treatment of liver metastasis and peritoneal dissemination of gastric cancer using intra-arterial therapy--a case report].

A 56-year-old man who had undergone curative gastrectomy for Borrmann 2 type gastric cancer 43 months before, had a cancer recurrence (liver metastasis and peritoneal dissemination). Intra-arterial hypertensive chemotherapy with MMC for liver metastasis and intra-arterial sequential MTX/5-FU chemotherapy for peritoneal dissemination were given. He died of lung cancer with brain metastasis 27 months after this therapy. But in autopsy the remarkable effects of chemotherapy were recognized in intra-abdominal recurrent sites, and in fact, microscopically no cancer cells were found in metastatic lesions. We thus concluded that intra-arterial noradrenaline-induced hypertensive MMC therapy for liver metastasis and intra-arterial sequential MTX/5-FU therapy for peritoneal dissemination were useful treatment.
