hepatic arterial infusion pump for HAI therapy and

- Histologically or cytologically proven measurable metastatic colorectal cancer

disease by preoperative radiological studies. Limited resectable extrahepatic
disease is acceptable.

- No chemotherapy, radiotherapy, or biologic therapy for their malignancy in the 4
weeks prior to the liver perfusion and must have recovered from all side effects.

- An ECOG performance standard of 0, 1 or 2 for 24 hours prior to surgery.

- Adequate hepatic function as evidenced by bilirubin < 2.0 mg/dL and a PT < 2 seconds
greater than the upper limit of normal.

- Age equal to 18 years or older and greater than 30 kg.

- Platelet counts greater than 100,000, a hematocrit > 27.0, a white blood count >
3000/microliter, and a creatinine less than or equal to 1.5 mg/dL or a creatinine
clearance of > 60 mL/min. Patients with elevations in hepatic transaminases
secondary to the presence of metastatic disease in the liver are eligible.

- Aware of the neoplastic nature of his/her illness, the experimental nature of the
therapy, alternative treatments, potential benefits, and risks and willing to sign an
informed consent.

- The disease in the liver must be considered unresectable as defined by greater than
three sites of disease in the liver, bilobar disease, and tumor abutting major
vascular or ductal structures making anatomic resection with preservation of liver
function impossible.

LVEF < 40% will be excluded.

- Patients with COPD or other chronic pulmonary disease with PFT's indicating an FEV<
50% predicted for age will be excluded.

- Patients with a history of veno-occlusive disease of the liver are ineligible.
