We conducted overseas research, mainly in Europe (SIOPEL) and North America(COG), on cases of hepatoblastoma, which account for over 80% of all pediatric liver tumors.. In Japan, the rate of incidence was higher than in these countries, but the incidence of pathologically small undifferentiated tumors was lower.. According to the outcome of the patients, we stratified the hepatoblastoma patients into three risk groups : standard, intermediate, and high risks and proposed new treatment protocols for each group. We also built a new pathological classification scheme and registration database, to pave the way for international collaboration in infrastructure development for clinical trials.
