Hepatic cryotherapy shows promising survival for liver metastases with acceptable morbidity and mortality. Tumor marker normalization indicates efficacy, though long-term data are needed for comparison.

Area of Science:

  • Oncology
  • Surgical Oncology
  • Interventional Radiology

Background:

  • Nonresectable liver tumors present a significant treatment challenge.
  • Cryotherapy is re-emerging as a viable option for liver metastases.

Purpose of the Study:

  • To evaluate the morbidity, mortality, and efficacy of hepatic cryotherapy for liver metastases.
  • To assess patient outcomes following cryosurgical procedures.

Main Methods:

  • Prospective case-control study of 49 patients undergoing 54 hepatic cryotherapy procedures.
  • Data collected on patient demographics, tumor characteristics, and operative details.
  • Median follow-up of 13 months.

Main Results:

  • Low postoperative mortality (2%) and reversible complications (27%).

  • Tumor marker (CEA) normalization in 76% of eligible patients.
  • Median overall survival of 23 months; 29 months for colorectal metastases.

    • Conclusions:

    • Hepatic cryotherapy offers tolerable morbidity and mortality for liver metastases.
    • Efficacy is supported by tumor marker response.
    • Promising survival data warrant further long-term evaluation and comparison with other treatments.
