Irinotecan-Eluting Beads in Treating Patients With Refractory Metastatic Colon or Rectal Cancer That Has Spread to the Liver

PRIMARY OBJECTIVES: I. To determine the maximum tolerated dose of drug eluting irinotecan (irinotecan hydrochloride) beads (irinotecan-eluting beads), delivered intrahepatically for the treatment of liver only or liver-predominantly colorectal metastatic disease. SECONDARY OBJECTIVES: I. To determine the response rate of colorectal liver metastases treated with drug-eluting irinotecan beads in refractory metastatic colorectal patients with liver only or liver predominant disease. II. To determine the time to progression of colorectal liver metastases treated with drug-eluting irinotecan beads in refractory metastatic colorectal patients with liver only or liver predominant disease. III. To determine the overall survival of patients treated with drug-eluting irinotecan beads for liver only or liver predominant metastatic disease from colorectal cancer. OUTLINE: This is a dose-escalation study. Patients receive irinotecan-eluting beads via hepatic artery embolization every 3 weeks for a total of 2 treatments in the absence of disease progression or unacceptable toxicity. Patients with bi-lobular disease and no evidence of progression in the treated lobe may repeat treatment at the discretion of the treating physician. After completion of study treatment, patients are followed up at 30 days and then every 3 months for 2 years.
