[Intraarterial infusion combination therapy with LV and 5-FU in hepatic metastases from colorectal cancer].

Intraarterial infusion combination therapy with LV and 5-FU was performed on 8 patients with hepatic metastases from colorectal cancer. Briefly, immediately after administration of LV 30 mg/body, 5-FU was administrated in doses of 750 to 1,250 mg/body over about 2 hours. The therapy was repeated at every weekly visit to the clinic. The number of courses per patient averaged 22. The response rate was 50% (4 PR). Clinical responses were obtained 6 months on average. The 50% survival period was 300 days. Five patients died, 3 due to metastases to other sites. This therapy on an out-patient basis could be continued in all but one patient who was withdrawn from the treatment because of leucopenia. The results of this study suggest that this combination therapy is effective for hepatic metastasis from colorectal cancer.
