Radiofrequency ablation in the treatment of liver tumors in children

Hepatoblastoma and liver metastasis of Wilms' tumors are rare hepatic tumors in children. Treatment of both tumors consists of a combination of chemotherapy and liver surgery. Radiofrequency ablation (RFA) is frequently used for the treatment of adult liver tumors but is rarely mentioned as a treatment option in pediatric liver tumors. We present a patient with hepatoblastoma and 1 with liver metastasis from a Wilms' tumor. Both patients were treated according to the latest protocols except that surgery included use of RFA. Both are well and recurrence free 8 and 3 years after surgery. Radiofrequency ablation may be a good addition to the existing arsenal of treatment modalities for pediatric liver tumors.
