Mao R, et al. - The effectiveness of percutaneous radiofrequency ablation (RFA) vs repeat hepatectomy for resectable recurrent colorectal liver metastases (CRLM) was determined via a retrospective review of 104 patients (61 undergoing RFA and 43 undergoing repeated surgery) treated for resectable recurrent CRLMs. Findings justify percutaneous RFA for certain patients with resectable recurrent CRLM. RFA and hepatectomy resulted in comparable progression free survival (PFS). Local treatment was repeated in 69.7% of RFA patients and 42.6% of surgery patients with intrahepatic recurrence. RFA treatment, tumors size, and tumor number were noted to have an independent association with recurrence. Survival was noted to have an independent association with extrahepatic disease and old age.
