BACKGROUND: Hepatoblastoma is a rare tumour accounting for approximately 1% of all paediatric malignancies. Hepatoblastoma complicated by pulmonary metastatic disease continues to cause management difficulties due to a lack of robust evidence and treatment guidelines.
METHOD: This series is the experience of a tertiary paediatric referral centre. Patients were prospectively enlisted, and their charts were retrospectively reviewed.
RESULTS: Thirty-seven patients were treated for hepatoblastoma from 1995 to 2012 inclusive. The overall survival was 34/37(91.9%). Eight patients had lung metastases at diagnosis (LMD) and twenty-nine did not (NLMD). Two-year EFS was 62.5% in the LMD group and 89.3% in the NLMD group (p=0.078). Overall survival in the LMD and NLMD groups was 100% and 89.7%, respectively (p=0.389). Two patients in the LMD group required multiple thoracic resections to achieve cure. Within the NLMD group, two patients developed lung metastases whilst on treatment, and both of these patients died.
CONCLUSION: In this series, children presenting with lung metastases had a higher risk of relapse but excellent overall survival. However, children who developed pulmonary disease during treatment had a poor prognosis. We advocate aggressive surgical treatment of pulmonary hepatoblastoma to achieve cure.
