A Phase I Study of Isolated Hepatic Perfusion With Escalating Dose Melphalan Followed by Postoperative Hepatic Arterial Floxuridine and Leucovorin for Metastatic Unresectable Colorectal Cancers of the Liver

Histologically or cytologically proven measurable metastatic colorectal cancer limited to the parenchyma of the liver with no evidence of unresectable extrahepatic disease by preoperative radiological studies. Limited resectable extrahepatic disease is acceptable. Patients must not have been previously treated with intrahepatic artery infusional therapy using FUDR. Patients mush have had no chemotherapy, radiotherapy or biologic therapy for their malignancy in the month prior to the liver perfusion and must have recovered from all side effects. Patients must have an ECOG performance standard of 0, 1 or 2 on the day prior to treatment. Patients must have adequate hepatic function as evidence by bilirubin less than 2.0 and a PT and PTT that are within 1-2 seconds of the upper normal limit. Patients must not have biopsy proven cirrhosis or evidence of significant portal hypertension by history, endoscopy, or radiologic studies. Patients must not have a history of congestive heart failure with an LVEF less than 40%. Patients must not have COPD or other chronic pulmonary disease with PFT's less than 50% predicted for age. Patients must be 18 years of age or older. Patients must have a platelet count greater than 100,000 a Hct greater than 27.0, a white blood count greater than 3000/micro liters, and a creatinine less than or equal to 1.5 or a creatinine clearance of greater than 60 ml/min. Patients must not be pregnant or nursing. Patients must not be taking immunosuppr…
