title: Weekly hepatic arterial infusion of 5-fluorouracil and subsequent systemic chemotherapy for liver metastases from colorectal cancer.
abstract: OBJECTIVE
  To determine the antitumor activity and toxicity of weekly hepatic arterial infusion (HAI) of 5-fluorouracil (5-FU) for liver metastases from colorectal cancer. In addition, the present study also evaluated the efficacy of second-line chemotherapy after termination of HAI.
  
  
  METHODS
  A retrospective study was designed to evaluate the clinical outcome in patients treated with HAI. Twenty-six patients with liver metastases from colorectal cancer were treated with 5-FU 1000 mg/m(2) over 5 h once per week on an outpatient basis. The treatment was continued until disease progression, unacceptable toxicity or the patient's refusal to continue treatment occurred. One of three kinds of second-line systemic chemotherapy, irinotecan alone, protracted venous infusion of 5-FU or methotrexate (MTX) and 5-FU, was chosen after termination of HAI.
  
  
  RESULTS
  An objective tumor response to HAI was observed in 46% (95% confidence interval, 26.9-65.2%) of 26 patients. The most common adverse events were mild nausea and vomiting (35%) and occurrence of gastroduodenal ulcers (15%). Hematological toxicity was minimal. No responder was observed to improve following second-line chemotherapy after termination of HAI.
  
  
  CONCLUSIONS
  Weekly HAI of 5-FU is both active and well tolerated. However, extrahepatic progression was observed in one-third of patients with termination of HAI and the efficacy of second-line chemotherapy was not demonstrated. Regional treatment with systemic chemotherapy should be conducted to achieve good results in terms of survival.
