Impact of Prior Hepatectomy History on Local Tumor Progression after Percutaneous Ablation of Colorectal Liver Metastases.

ABSTRACT: PURPOSE:To test the hypothesis that, given the current resection eligibility criteria for colorectal liver metastasis (CLM), prior hepatectomy would be associated with improved local tumor control and survival after percutaneous ablation of CLMs. MATERIALS AND METHODS:This single-institution retrospective study included 82 consecutive patients with 97 CLMs treated with ablation (radiofrequency ablation, microwave ablation, or cryoablation) from January 2005 to December 2014. Local tumor progression-free survival (LTPFS), recurrence-free survival (RFS) at any organ, and overall survival (OS) were calculated using the Kaplan-Meier method from the time of ablation and compared between patients with (n = 49) and without (n = 33) prior hepatectomy. Cox regression models were used to identify LT
