allowed to establish a new universal risk stratification system for HB . Concomitant international
collaboration of pediatric pathologists made it possible to use the collected data to establish a new
international histopathologic consensus classification for pediatric liver tumors as a whole, with particular
focus on the histological subtypes of HB [9,10] .

During the same period, advances in chemotherapy options developed, an increased role of liver
transplantation for unresectable tumors was established, and a web portal system was created at
www.siopel.org for international education, consultation, and collaboration. These achievements are
currently further tested and validated in the running Paediatric Hepatic International Tumour Trial
(PHITT).

This small collection of papers on this subject invites the interested reader to further explore the existing
literature on the achievements in the field of Pediatric Liver Tumors that have been established during the
past decades .
