Long-term outcomes following percutaneous microwave ablation for colorectal cancer liver metastases.

Purpose: To evaluate the overall survival (OS), local progression-free survival (PFS) and prognostic factors of patients with colorectal cancer liver metastases (CRLM) undergoing microwave ablation (MWA).

Method: A total of 132 patients were retrospectively enrolled who had been treated between 2010 and 2018. For the evaluation of survival rates, all patients were divided according to their indications (curative  = 57 and debulking (patients with additional non-target extrahepatic metastases)  = 75).
