Long-term local disease control in a recurrent soft-tissue sarcoma of the thigh treated by radiofrequency ablation

In 2008, we performed radiofrequency ablation (RFA) in an elderly patient with a large recurrent soft-tissue sarcoma of the thigh, previously treated with surgery and radiotherapy. After ablation, a marked shrinkage of tumor was obtained. Further local recurrences occurred during follow-up, all safely treated by RFA, with local control of the disease maintained until 6-year follow-up. RFA was safe, effective, and repeatable for soft-tissue sarcoma recurrences, and allowed long-term local control of the disease.
