Area of Science:

  • Oncology
  • Surgical Oncology
  • Interventional Radiology

Background:

  • Primary liver cancer (PLC) presents significant treatment challenges.
  • Cryotherapy, utilizing liquid nitrogen at -196°C, is an established oncological intervention.
  • Assessing the long-term efficacy of cryotherapy in PLC management is crucial.

Purpose of the Study:

  • To evaluate the safety and effectiveness of in situ tumor cryotherapy for primary liver cancer.
  • To determine the 5-year survival rates associated with cryotherapy in PLC patients.
  • To compare different cryotherapy-based treatment modalities for PLC.

Main Methods:

  • Cryotherapy using liquid nitrogen was performed on 235 primary liver cancer patients between 1973 and 1996.
  • Patient data were analyzed for operative mortality, complications, and 5-year survival rates.
  • Survival outcomes were stratified by tumor size and specific treatment combinations involving cryotherapy.

Main Results:

  • No operative mortalities or severe complications were observed.
  • Overall 5-year survival for 235 PLC patients was 39.8%.
  • Patients with small PLC (< or = 5 cm) had a higher 5-year survival rate of 55.4%.

Conclusions:

  • Cryotherapy is a safe and effective treatment modality for primary liver cancer.
  • Combined treatments, such as cryotherapy followed by resection, yielded the highest survival rates.
  • Cryotherapy offers a viable therapeutic option for managing primary liver cancer.
