Brief summary: RATIONALE: Drugs used in chemotherapy, such as melphalan, work in different ways to stop tumor cells from dividing so they stop growing or die. Giving chemotherapy 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 unresectable colorectal cancer that has metastasized to the liver.

Detailed description: OBJECTIVES:

Primary

* Determine the response and duration of response in patients with unresectable colorectal cancer metastatic to the liver and refractory to first-line systemic chemotherapy treated with isolated hepatic perfusion with melphalan.

Secondary

* Determine the pattern of recurrence (liver vs systemic) in patients treated with this regimen.
* Determine hepatic progression-free and overall survival in patients treated with this regimen.
* Determine the time to hepatic and systemic progression in patients treated with this regimen.
* Determine quality of life (QOL) in patients treated with this regimen.
* Correlate baseline QOL with length of survival in patients treated with this regimen.

OUTLINE: Patients undergo a limited laparotomy to determine if extrahepatic disease that was not visualized during preoperative scanning is present. Patients found to have peritoneal seeding or unresectable extrahepatic metastatic disease not previously visualized on scans do not receive isolated hepatic perfusion (IHP). Remaining patients undergo IHP with melphalan and hyperthermia therapy. Liver perfusion continues for 1 hour.

Quality of life is assessed at baseline, 6 weeks, and then every 3-4 months for 3 years.

Patients are followed at 6 weeks, every 3-4 months for 3 years, and then every 6 months thereafter.

PROJECTED ACCRUAL: A total of 30 patients will be accrued for this study within 3 years.

Eligibility criteria: DISEASE CHARACTERISTICS:

* Histologically or cytologically confirmed colorectal cancer

  * Metastatic disease limited to the parenchyma of the liver

    * Patients with limited sites of extrahepatic disease AND who have dominant life-limiting disease in the liver are considered eligible provided the extrahepatic sites can be treated with local ablative measures (e.g., resection or external beam radiotherapy)
    * No other evidence of unresectable extrahepatic disease by radiological studies
* Unresectable hepatic disease defined by \> 3 sites of disease in the liver, bilobar disease, or tumor abutting major vascular or ductal structures making anatomic resection with liver function preservation impossible
* Measurable disease
* Refractory to prior first-line systemic chemotherapy

  * Disease progression during or after completion of treatment with an irinotecan- or oxaliplatin-containing regimen for established hepatic metastases

    * Treatment failure is defined as disease progression evidenced by tumor growth OR new lesions on imaging modalities OR increasing carcinoembryonic antigen (CEA)
