Methods and materials
A retrospective review of the medical records of 37 patients with RCC lesions measuring 4 – 7 cm who underwent percutaneous cryoablation from 2004-2018 was performed.
technical parameters of the procedure,
and local recurrence rates were recorded.
The RENAL and PADUA scores were calculated and patients were categorized accordingly. Technical success and complications were analyzed.
Technical success was defined by the absence of new contrast enhancement and the absence of tumor enlargement within 3 months of ablation.
Local recurrence was defined as persistent or recurrent tumor evident by new contrast enhancement within the ablation zone or enlargement of the ablated tumor 3 months or later following ablation. Recurrence free,
cancer specific and overall survival rates were estimated using the Kaplan-Meier method.
A uni-variate analysis was performed to identify any potential predictors of complications,
