    Hepatic resection for metastatic disease offers prolonged survival, especially for colorectal cancer patients with early-stage or metachronous tumors. This surgical approach demonstrates acceptable risks and improved outcomes.

    Area of Science:

    • Hepatobiliary Surgery
    • Surgical Oncology
    • Colorectal Cancer Metastasis

    Background:

    • Metastatic disease to the liver significantly impacts patient prognosis.
    • Hepatic resection is a potential curative treatment for selected patients with liver metastases.
    • Evaluating outcomes of hepatic resection for diverse metastatic liver tumors is crucial.

    Purpose of the Study:

    • To review outcomes of hepatic resection in patients with metastatic disease.
    • To identify factors influencing survival after liver resection for metastases.
    • To assess the safety and efficacy of hepatic resection for liver metastases.

    Main Methods:

    • Retrospective review of 30 patients undergoing hepatic resection for metastatic disease.
    • Analysis of primary tumor sites, operative procedures, and complications.

  • Life-table analysis to project survival rates based on tumor characteristics and surgical approach.

    • Main Results:

    • The study included 30 patients with a mean age of 58.9 years; 25 had colorectal primary tumors.
    • Major complications occurred in 7 patients; the operative death rate was 6.7%.
    • Projected 5-year survival was 50.3% for colorectal primaries, with better outcomes for metachronous tumors and earlier Dukes' class lesions.

    Conclusions:

    • Hepatic resection for metastatic disease is associated with acceptable morbidity and mortality.
    • The procedure offers the potential for substantially prolonged survival, particularly in patients with metachronous colorectal metastases or Dukes' A or B primary lesions.
    • Surgical approach (wedge resection/segmentectomy vs. lobectomy) may influence survival outcomes.
