Radiofrequency ablation (RFA) was evaluated with regard to long-term survival and the rate of complications in the treatment of colorectal liver metastases. 102 patients (332 tumours) were treated. Treatment monitoring was conducted with CT. Survival was estimated with the Kaplan-Meier method. Median survival was 52 months. Five-year survival was 44%. Major complications were seen following 12 RFA treatments (6.9%). RFA offers efficient treatment of colorectal liver metastases. Survival is similar to surgical resection. Complication rates are low.
