Core Tip
Core tip: Colorectal liver metastasis is diagnosed in approximately 50% of patients with colorectal cancer. Surgical resection is the optimal treatment strategy. Alternative local treatment modalities can be adapted, and radiofrequency ablation (RFA) is widely accepted. We examined whether RFA is an appropriate alternative method to surgery for resectable colorectal liver metastases. This study retrospectively compared the therapeutic efficacy of RFA and compared it with that of surgical resection in a single institute.
