    Abstract:
    Before Dec. 1993, we resected 17 patients with hepatic metastases from colorectal cancer. Hepatic recurrences developed in 82% patients who had been given mitomycin C or doxorubicin by hepatic-artery. The one-, 3- and 5-year survival rate after surgery was, 88%, 18% and 12%, respectively. Therefore, some new types of adjuvant therapy were needed to improve survival after surgery. This is a retrospective study to determine whether preventive intrahepatic artery infusion chemotherapy (HAI) and repeated hepatectomy are of benefit for patients with hepatic metastases from colorectal cancer who underwent hepatectomy. Thirty-five patients with hepatic metastases from colorectal cancer underwent hepatectomy and were administered 1,500 mg of 5-FU 10 times via the hepatic artery for 5 hrs every 1-2 weeks to prevent hepatic recurrence after Jan. 1994. Nine patients underwent repeated hepatectomy, then HAL following the operation. Non-resectable recurrence were treated by HAI. The amounts of the infused 5-FU dose were 8.5-46.5 g (mean 23 g) and 17-31 times HAI (mean 22 times). Survival rates were 81, 67, 67% and 24%, respectively, after 1, 2, 3 and 4 years. Hepatic disease-free interval rates were 49.3% and 32.5%, respectively, after 1 and 2 years. Preventive HAI could not control hepatic recurrence but prognosis after hepatectomy was improved by these modalities compared with treatment before Dec. 1993. Survival rates of 9 patients who underwent repeated hepatectomy were 89, 89% and 37%, respectively, after 1, 3 and 4 years. The prognosis of patients with hepatic metastases from colorectal cancer was improved by HAI and repeated hepatectomy, but further studies should be undertaken to improve preventive HAI.
