2. Hepatic and intra-abdominal metastases must be measurable by computed tomography (CT), magnetic resonance imaging (MRI) and/or positron emission tomography (PET) scan
3. Liver disease must be amenable to gross total resection (R0/R1) with adequate functional liver remnant which requires preservation of at least 2 contiguous hepatic segments with adequate inflow, outflow, and biliary drainage with a functional liver remnant (FLR) volume of more than 20% (for healthy liver)
4. Greater than or equal to 18 years of age.
5. Must be able to understand and sign the Informed Consent Documentation.

   * Hemoglobin greater than 8.0 g/dl.
10. Chemistry:

    * Serum creatinine less than or equal to 1.5 mg/dl unless the measured creatinine clearance is greater than 60mL/min/1.73m\^2.
    * Total bilirubin less than or equal to 2 mg/dl, except for patients with diagnosis of Gilberts disease or hepatic pedicle obstruction then total bilirubin must be less than or equal to 5 mg/dl.
