A recent study, published in the Journal of Cancer, conducted a systematic review and meta-analysis of the outcomes data for the use of cryoablation versus partial nephrectomy for early stage (T1) renal tumours.

The review showed that cryoablation is linked with poorer oncologic outcomes than partial nephrectomy, but patients who underwent cryoablation had lower rates of complications and better preservation of renal function.

The researchers conclude that for patients who are indicated for nephron-sparing surgery and who can’t risk more invasive partial nephrectomy, cryoablation could be an attractive option. However, they mention that their conclusions should be treated with caution due to the limitations of the studies included in the meta-analysis, and should be confirmed further with well-designed randomised controlled trials with extensive follow-up.
