Hepatic Arterial Infusion With Floxuridine and Systemic Irinotecan After Surgery in Treating Patients With Hepatic (Liver) Metastases From Colorectal Cancer

RATIONALE: Drugs used in chemotherapy such as floxuridine and irinotecan use different ways to stop tumor cells from dividing so they stop growing or die. Hepatic arterial infusion uses a catheter to deliver chemotherapy directly to the liver. Combining more than one drug and giving them in different ways may kill any tumor cells remaining after surgery. PURPOSE: Phase II trial to study the effectiveness of systemic irinotecan and hepatic arterial infusion with floxuridine after surgery in treating patients who have hepatic (liver) metastases from colorectal cancer.
