The current application of thermal ablation in colorectal liver metastasis

Colorectal liver metastases(CRLM)are one of the most frequent clinical conditions.Over the last 20 years,the clinical outcome for patients with CRLM has improved greatly.Liver resection is the gold standard treatment for resectable CRLM,achieving a 5-year overall survival(OS)rate of 42%(1).However,the majority of patients with CRLM are not candidates for resection.With the development of thermal ablation,this technique provides an alternative treatment modality by either ablation alone or combined with resection.A recent review by Takahashi et al.summarized the current role of thermal ablation in the management of CRLM(2).
