    Abstract:
    BACKGROUND: Excellent outcomes of the extreme procedure of liver resection (LR) for advanced hepatoblastoma (HB) have been achieved in recent reports. However, liver transplantation (LT) remains the only surgical treatment for patients with unresectable HB. The aim of this study was to evaluate our retrospective data for cases of advanced HB necessitating surgical intervention and analyze the prognostic factors of recurrence by comparing patients with tumors resected by LR and LT. PATIENTS AND METHODS: We retrospectively reviewed 24 children with PRETEXT II/III/IV tumors that required consideration for LT between August 2011 and September 2016. RESULT: The staging at the time of the diagnosis was PRETEXT II/III/IV in 1/13/10 patients, respectively, while the preoperative staging after neoadjuvant chemotherapy was POSTTEXT II/III/IV in 5/17/2 patients. Among those 24 patients, complete resection of the primary tumor was achieved with LT in 12 patients and LR in 12 patients. A high serum level of alpha-fetoprotein (AFP) at the time of surgery, no significant decrease in the rate of change of AFP, and low tumor shrinkage rate were related to the risk of tumor recurrence, and patients with tumors resected by LR with those risks had a higher recurrence rate than those without them. The overall survival was higher in patients with tumors resected by LT (100%) than in patients with tumors resected by LR. CONCLUSION: Patients with advanced HB with a poor response to chemotherapy should definitively be prioritized for primary LT, given the possibility of vascular invasion and microscopic residual tumor.
