Thirty-two patients with colorectal cancer, eleven with gastric cancer and two with pancreatic cancer were treated by hepatic arterial infusion chemotherapy from March 1988 to December 1999. A single administration of 5-FU, MMC and epirubicin (FAM group), or intermittent continuous infusion of 5-FU 500 mg/2 h (5-FU continuous group) was used for each patient once a week. Overall survival rates were not significantly different between the gastric and colorectal cancer patients. In patients with colorectal cancer, there was a significant prolongation in overall survival for the response group. With gastric cancer, however, there was no significant difference. For both of the two patients with pancreatic cancer, although they were responsive to the therapy, there was no prolongation of survival. In conclusion, intermittent continuous infusion was more effective for the patients with colorectal cancer. In patients with gastric and pancreatic cancer, hepatic intra-arterial infusion could control the progression of liver metastasis.
