Cryotherapy is increasingly used and has been included in guidelines for selected tumor entities such as renal cell carcinoma. Cryo-immunotherapy and combination treatments are future areas of interest.
Cryoabalation may be used in many indications. Its major advantages are its unique visualization and the anesthesiologic effects of cold. While there are only a few prospectively randomized trials, the existing data on the use of cryoablation is promising. Its use appears to be justified in selected tumors, oligometastatic patients and for palliative indications.
