BACKGROUND: Hepatoblastoma is a rare malignancy but the most common primary hepatic malignancy in childhood. Pediatric liver transplantation (LT) offers the possibility to achieve a complete resection in otherwise unresectable tumors. Almost no data are available regarding specific surgical technique of LT in children with hepatoblastoma.
METHODS: We analyzed all children with hepatoblastoma and LT between 2007 and 2012. Special regard was given to the surgical technique and long-term follow-up.
RESULTS: Overall 7 children were transplanted with the diagnosis of hepatoblastoma (5 male, 2 female). Thereof, 4 children (median age was 11 months, range, 6-31 months) underwent "primary" LT for hepatoblastoma Pretreatment Extent of Disease III to IV. A 4-year-old boy received "salvage" LT for recurrent hepatoblastoma 2.5 years after successful liver resection. Another 15-year-old boy was transplanted as a prophylactic treatment after repeated liver resection for hepatoblastoma due to the high recurrence risk. A 14-year-old boy underwent LT due to complications following liver resection for hepatoblastoma during infancy. In all children, extensive en bloc hepatectomy was performed together with resection of the adjoining retroperitoneal tissue and regional lymphadenectomy. Actually, all children are alive without tumor recurrence median 7.1 years after LT (range, 5.7-10.7 years).
CONCLUSION: Our data show an excellent long-term outcome in selected children with hepatoblastoma undergoing standardized en bloc hepatectomy for "primary" and "rescue" LT with 100% overall and recurrence-free survival.
