Cryoablation could be as effective as surgery for the treatment of early-stage kidney cancer

Research led by Christos Georgiades (Johns Hopkins University, MD, USA) has demonstrated that cryoablation is as effective as standard surgical options for the treatment of early-stage kidney cancer. The findings – published recently in Radiology – also suggested that cryoablation could offer lower rates of complication.Percutaneous cryoablation is minimally invasive and considered as an alternative to surgery. Under imaging guidance, argon gas is circulated through a hollow needle that has been inserted into the tumor. A small portion of the tumor and the surrounding tissue is frozen, killing the tumor, which becomes scar tissue that is absorbed. The standard surgical...
