Liver Tumours in Children • Hepatoblastoma (HBL)* • Hepatocellular carcinoma (HCC)* • Sarcomas • NHL • MGCT* • Benign tumours** * AFP raised ** AFP normal for age
Hepatoblastoma • More boys than girls – 1.5:1 • Some tumours multifocal • Mean age 20 months, rare above 5 yrs • Over 95% sporadic, 2-3% predisposed (BWS, FAP) • Pancreatoblastoma is a similar tumour • 1 in 60,000 children so cooperationmandatory
Hepatoblastoma • Prenatal diagnosis • Endocrine syndrome • Thrombocytosis in a ‘poorly’child • Non-accidental injury • ‘Second tumour’ (BWS)
Hepatoblastoma • Essential Investigations • MRI/CT of liver • CXR plus CT of lungs • Renal, auditory, cardiac function • FBC and coagulation
