Primary hepatic tumors of childhood

Abstract

A clinicopathologic review of 73 cases of primary liver tumors at Texas Children's Hospital, Houston, and Children's Medical Center, Dallas, has documented important prognostic and therapeutic implications for the histologic classification of hepatoblastoma. The pure "fetal" pattern was associated with cure in every instance that surgical excision was achieved (six of six patients), whereas only two of 19 patients with "embryonal" or other undifferentiated patterns of growth survived five years. The relationship of hepatoblastoma and hepatocarcinoma in childhood to antecedent conditions is discussed in detail. The uncommon liver sarcomas are also reviewed in the light of experience at these two institutions.
