Background: Hepatic arterial infusion chemotherapy is a promising approach in liver metastases from colorectal cancer, but chemical hepatitis, biliary sclerosis, arterial thrombosis and right upper quadrant pain are limiting factors. Irinotecan (CPT-11) is an active drug in colorectal cancer. We planned a short hepatic arterial infusion of CPT-11 to describe the toxicity, to determine the dose-limiting toxicity, and to define the doses of CPT-11 to be recommended for phase II studies. Patients and methods: Fourteen patients with a median liver substitution of 30% (10-60%) were enrolled. All patients received hepatic arterial infusion chemotherapy with CPT-11 on an out-patient basis every 3 weeks as a short, 30-min infusion. Results: At 240 mg/m2, 2 of 4 patients experienced grade 4 diarrhea and neutropenia, and 3 of them also reported grade 4 abdominal pain of the right upper quadrant. The maximum tolerated dose was reached at 240 mg/m2. The recommended doses of CPT-11 for phase II studies is 200 mg/m2, given every 3 weeks. Conclusions: CPT-11 presents a low hepatic toxic profile and could be considered a new active drug, suitable for hepatic arterial infusion in liver metastases from colorectal cancer.
