[A case of gastric cancer with marked response to intra-arterial infusion of cisplatinum, mitomycin C and 5-fluorouracil].

The prognosis for patients with unresectable gastric cancer is so poor that 50% survival time is no more than 3 months. A 58-year-old woman was admitted for advanced gastric cancer with multiple liver metastases. Preoperatively, she received hepatic arterial infusion of 75 mg/m2 of cis-platinum during abdominal angiography. As laparotomy revealed an unresectable gastric tumor of the classification H3P2N4S3, a catheter was introduced into the aorta at the level of the celiac axis via a branch of the right femoral artery and 10 mg of Mitomycin C was infused into the abdominal aorta through the catheter. Postoperative chemotherapy consisted of continuous intra-arterial infusion of 250 mg/day of 5-Fluorouracil for 14 days, followed by infusion of another 10 mg of Mitomycin C. Daily oral administration of 600 mg of tegafur was continued in the outpatient clinic. Three months after surgery, the primary and hepatic metastatic lesions had regressed by 76 and 88-98% on abdominal computed tomography and gastric fluoroscopy, respectively. The dimensions of the lesions remained unchanged for the subsequent two months, and their responses to the treatment were judged PR. Eight months after surgery, the patient is in good general condition.
