Effectiveness and safety of computed tomography-guided radiofrequency ablation of XXXX : a 14-year single institution experience in 203 @entity1 .

@entity1 @entity66 @entity5 @entity1358 @entity703
OBJECTIVES: To define effectiveness and safety of CT-guided radiofrequency ablation (RFA) of @entity703 and prognostic indicators for treatment success. METHODS: @entity1 with a single treatment of a solitary, biopsy-proven @entity703 with intent to cure over a 14-year period were included (n   =   203). Probability of @entity66 over time, complication rates and all-cause mortality were assessed in relation to multiple variables. RESULTS: Mean @entity5 size was 2.5  cm (range 1.0-6.0). Mean follow-up was 34.1  months (range 1-131). There was an increase in likelihood of @entity66 for @entity5 >= 3.5  cm (P   <   0.05), clear cell subtype of @entity1358 (P    <=   0.005) and maximum treatment temperature  <=70    C (P   <   0.05). There was a decrease in likelihood of @entity66 for @entity5 (P   =   0.01) and no difference based on age, gender, @entity5 location or type of radio freqency (RF) electrode used. Major complications occurred in 3.9  %. Median post-treatment survival was 7  years for @entity1 with @entity5 <4  cm, and 5-year overall survival was 80  %. Probability of minor complication increased with @entity5 size (P   =   0.03), as did all-cause mortality (P   =   0.005). CONCLUSIONS: CT-guided RFA is safe and effective for @entity703 , particularly for @entity5 measuring <3.5  cm. Overall 5-year survival with @entity5 <4  cm is comparable to partial nephrectomy. KEY POINTS:     Prognostic indicators for success of CT-guided RFA of @entity703 are reported.     @entity5 size >= 3.5  cm confers an increased risk for @entity5 .     @entity1358 subtype confers increased risk for @entity5 .     Tmax <70    C within the ablation zone confers increased risk for @entity5 .     @entity5 have a lower probability of @entity66 .
