Clinical trial: Isolated Hepatic Perfusion With Melphalan in Treating Patients With Primary Unresectable Liver Cancer or Liver Metastases

Summary: RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving drugs in different ways may kill more tumor cells.
  PURPOSE: This phase II trial is studying how well isolated hepatic perfusion with melphalan works in treating patients with primary unresectable liver cancer or liver metastases.

Detailed description: OBJECTIVES:
  -  Determine response rate, duration of response, and patterns of recurrence in patients with primary or metastatic, unresectable cancers of the liver after treatment with isolated hepatic perfusion with melphalan.
  -  Determine the disease-free and overall survival of patients treated with this regimen.
  OUTLINE: Patients who are otherwise eligible undergo an exploratory laparotomy of the peritoneal cavity. Patients with peritoneal seeding, unresectable extrahepatic metastases, or unresectable pathologically-involved lymph nodes outside area of portahepatis do not receive treatment. Remaining patients receive isolated hepatic perfusion with melphalan. Liver perfusion proceeds for 1 hour.
  Patients are followed at 6 weeks, every 3 months for 2 years, and then every 4 months until disease progression.
  PROJECTED ACCRUAL: A maximum of 67 patients will be accrued for this study.
