Effectiveness and safety of computed tomography-guided radiofrequency ablation of renal cancer: a 14-year single institution experience in 203 patients

Objectives To define effectiveness and safety of CT-guided radiofrequency ablation (RFA) of renal tumours and prognostic indicators for treatment success. Methods Patients with a single treatment of a solitary, biopsy-proven renal tumour with intent to cure over a 14-year period were included (n = 203). Probability of residual disease over time, complication rates and all-cause mortality were assessed in relation to multiple variables. Results Mean tumour 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 residual disease for tumours ≥3.5 cm (P
