Percutaneous renal cryoablation: local control at mean 26 months of followup
Atwell TD, Callstrom MR, Farrell MA et al.
In recent years, more cases of renal cell carcinoma (RCC) have been diagnosed, with an increase in the percentage of stage I disease and a decrease in the relative percentages of stages II– IV owing to the use of cross-sectional imaging and incidental diagnosis (Urology 2000;56:58–62, J Urol 2006;176:1317–20, Cancer 2008;113:78–83). While surgery may be the best therapeutic approach for localized disease, percutaneous cryoablation has been demonstrated to be promising in terms of achieving local control, particularly in patients who are ineligible for surgery. In the current study, the authors describe retrospective 2-year follow-up of patients whose renal masses had been treated with percutaneous cryoablation.
