title: A comparison between hepatic artery ligation and portal 5-Fu infusion versus 5-Fu intra arterial infusion for colorectal liver metastases.
abstract: OBJECTIVE
  A prospective randomized study was executed comparing two regimens of regional therapy for liver metastases from colorectal cancer.
  
  
  METHODS
  Eighteen patients were allocated to hepatic artery occlusion for 16 h followed by intraportal 5-fluorouracil (5-Fu) infusion (1000 mg/m(2)) for 5 days every sixth week (HAO). Twenty-one patients received intra-arterial 5-Fu infusion+Leucovorin (100 mg) i.v. for 2 days every second week (HAI). The follow up every third month included CT and CEA. Thirteen patients had limited extrahepatic cancer. At tumor progression regional therapy was stopped and systemic chemotherapy or the best supportive care was administered.
  
  
  RESULTS
  The study was discontinued after randomization of 39 patients. No significant difference in survival within patients with and without extrahepatic cancer was present. The mean survival was longer in the HAI group than for the HAO group (19 months versus 13 months, p=0.0147) (median 18 (8-37) versus 12 (2-26). PR and SD were registered in 8/18 in the HAO group and 17/21 patients in HAI group. The median time to progress was 4 (1-22) months versus 7 (1-23) months for the HAO and HAI group, respectively.
  
  
  CONCLUSIONS
  Regional intraarterial infusion with 5-Fu gives significantly better survival than hepatic artery occlusion followed by portal infusion. A limited amount of extrahepatic cancer does not influence survival time. A trial comparing hepatic artery 5-FU infusion and Leucovorin versus the most effective systemic therapy is warranted.
