[Radiofrequency ablation of hepatic metastases: clinical results]
Aim:
To establish the effectiveness of radiofrequency ablation in the treatment of metastatic hepatic lesions.
Patients And Methods:
104 pts with 231 metastases were treated with RFA. The volume of achieved destruction was assessed using imaging method and cytology. Patients were followed-up for 1-37 months.
Results:
87.3% of metastases < 3.0 cm, 50.9% of tumors sized 3.0-5.0 cm and 14.3% of metastases > 5.0 cm were completely destroyed. Major complications occurred in 7.5% of the patients. 34% of the ablated tumors recurred.
Conclusions:
The effectiveness of RFA metastases depends on the size and location of the lesion. Lesions adjacent to the gallblader and main bile ducts are risky for manipulation.
