AIMS: Radiofrequency ablation (RFA) has a role in the treatment of unresectable liver metastases either percutaneously or in open surgery. The aim of this study was to determine the feasibility and value using RFA, resection or in combination to cure liver metastases of colorectal or other origin. METHODS: Fifty-two consecutive patients were operated on with the intention to treat their liver metastases using both techniques of RFA and resection in the same curative intent. A CT scan was performed 2 months postoperatively and then every 4 months. RESULTS: Fifty patients with 137 metastases could be treated: 55 lesions were resected and 82 were ablated. Curative treatment of 13 patients could only be achieved by using RFA combined with resection. Morbidity was 16% and local treatment proved insufficient in three cases. Estimated 1-year survival probabilities were, respectively, 0.85 in the colorectal group and 0.80 in the non-colorectal group. CONCLUSIONS: RFA increased resectability of liver metastases and reduced the morbidity. Respective indications of both techniques were complementary and depend on the size and the topography of the lesion to be treated.
