INTRODUCTION: To assess the results and outcome of radiofrequency ablation in the treatment of recurrent @entity14 . @entity1 AND METHODS: Between January 2005 and September 2012, we treated 59 @entity1 with recurrent colorectal metastases not amenable to surgery with 77 radiofrequency ablation procedures. Radiofrequency was indicated if oncologic resection was technically not possible or the @entity1 was not fit for major surgery. A total of 91 lesions were treated. The mean number of @entity96 per @entity1 was 1.5, and the mean @entity5 diameter was 2.3 cm. In 37.5% of the cases, lesions had a subcapsular location, and 34% were close to a vascular structure. RESULTS: The morbidity rate was 18.7%, and there were no post-procedural deaths. Distant extrahepatic recurrence appeared in 50% of the @entity1 . Local recurrence at the site of ablation appeared in 18% of the lesions. Local recurrence rate was 6% in lesions less than 3 cm and 52% in lesions larger than 3 cm. The size of the lesions (more than 3 cm) was an independent risk factor for local recurrence (p < 0.05). Survival rates at 1, 3, and 5 years were 94.5%, 65.3%, and 21.7%, respectively. DISCUSSION: Radiofrequency ablation is a safe procedure and allows local @entity5 control in lesions less than 30 mm (local recurrence of 6%) and provides survival benefits in @entity1 with recurrent @entity14 .
