Abstract

Purpose

The aim of this retrospective study was to evaluate the clinical value of percutaneous radiofrequency ablation (RFA) for the treatment of renal cell carcinoma (RCC).

Materials and Methods

In a recent 3 years seven RCCs in six patients were treated by percutaneous RFA. RCC had been diagnosed based on the typical findings by computed tomography and/or magnetic resonance imaging. A cool-tip RF system (Vallylab) was mainly used with a RF2000 generator. The maximum tumor size ranged from 8 to 40 mm in diameter. The follow-up period was 14–36 months after initial RFA treatment.

Results

Complete disappearance of contrast enhancement during the early arterial phase was noted immediately after each session of percutaneous RFA. Two RCCs ≥ 3 cm in diameter showed tumor recurrence and required re-RFA during the follow-up period. In one patient, retroperitoneal hematoma was observed as a noteworthy complication.

Conclusion

Despite our limited number of patients, we believe that percutaneous RFA is clinically feasible and can be an alternative treatment of choice for RCC.
