['In children diagnosed with hepatoblastoma (HB), the lungs are the most common site of metastasis at both initial presentation and relapse. Previous studies have encouraged pulmonary metastasectomy to achieve a disease-free state after resection of the primary hepatic lesion. However, there is no consensus about how to manage recurrent pulmonary metastasis.', 'A retrospective, multi-institutional review was performed from 2005 to 2014 to identify HB patients ≤18years of age who had disease recurrence associated with pulmonary metastases alone.', 'Ten patients between the ages of 8 and 33months were identified. Pulmonary metastatic recurrence was detected by measuring alpha-fetoprotein (AFP) levels and/or with CT scans of the chest. All patients subsequently underwent pulmonary metastasectomy without post-operative complications. At last follow-up, 8 patients were alive and had normal AFP levels. The 8 survivors had a median follow-up from therapy completion of 18.5months. Two patients who presented with extrapulmonary recurrence subsequently died of treatment refractory disease.'] Is relapsed hepatoblastoma confined to the lung effectively treated with pulmonary metastasectomy?
