PURPOSE: To evaluate technique effectiveness, safety, and interoperator performance of stereotactic radiofrequency ablation (SRFA) of @entity409 . METHODS: Retrospective review including 90 consecutive @entity1 from January 2008 to January 2010 with 106 computed tomography-guided SRFA sessions using both single and multiple electrodes for the treatment of 177 lesions: 72 @entity157 ( @entity157 ) and 105 @entity3 with a mean size of 2.9 cm (range 0.5-11 cm). Technique effectiveness and 1-year local recurrence were evaluated by computed tomographic scans. Complications, mortality, and hospital days were recorded. The performance between an experienced and inexperienced interventional radiologist was compared. RESULTS: The overall technique effectiveness after a single SRFA was 95.5% (93.1% for @entity157 and 97.1% for @entity3 ). Four of the eight unsuccessfully treated lesions could be retreated (secondary technique effectiveness of 97.7%). Local recurrence at 1 year was 2.9%. Technique effectiveness was significantly different for lesions<5 cm (96.7%) and >5 cm (87.5%) (P=0.044) but not for lesions<3 cm (95.9%) and 3-5 cm (100%). Compared to clear parenchymal property (97.3%), vessel vicinity (93.3%) (P=0.349) and subcapsular (95.2%) (P=0.532) had no, but hollow viscera vicinity (83.3%) had a significantly lower technique effectiveness (P=0.020). Mortality rate was 0.9%. Major complications and hospital days were higher for @entity82 @entity1 -Pugh B (20%, 7.2 days) than @entity1 -Pugh A (3.1%, 4.7 days) @entity1 and for @entity3 (5.1%, 4.3 days). There was no significant difference in interoperator performance. CONCLUSION: SRFA allowed for efficient, reliable, and safe ablation of large-volume @entity409 .
