Patients with cT1a renal cell carcinoma (RCC) have better overall survival if they receive treatment with cryoablation instead of heat-based thermal ablation, a study found.

Jing Wu, MD, of Second Xiangya Hospital, Central South University, Changsha, Hunan, China, andcolleagues studied 6258 patients with cT1a RCC: 3936 treated with cryoablation and 2322 treated with heat-based thermal ablation. After propensity score matching, the cryoablation group had significantly longer median overall survival than the patients treated with heat-based thermal ablation (11.3 vs 10.4 years), the researchers reported in the Journal of Vascular and Interventional Radiology.
