BACKGROUND AND AIM: We reviewed the results and pattern of failure of the consensus HB/HCC 1996 treatment protocol for pediatric hepatoblastoma (HB) in Hong Kong. The role of SIOPEL and Children's Hepatic tumors International Collaboration (CHIC) risk stratification was evaluated.
METHODS: Patients enrolled on the protocol from 1996 to 2014 were included. PRETEXT staging, SIOPEL, and CHIC risk groups were retrospectively assigned.
RESULTS: Sixty patients were enrolled with median age at diagnosis of 1.1 years and median follow-up time of 6.8 years. Alpha-fetoprotein (AFP) was raised (>100 ng/mL) in 58 (97%) patients. Five (8%) had metastases at presentation and 7 (12%) experienced tumor rupture prior to or during treatment. Twenty-nine patients (48%) received a first-line cisplatin, 5-fluorouracil, and vincristine regimen only while 23 (38%) also had alternative chemotherapeutic agents. Hepatic resection could be performed in 48 (80%) patients. Three (5%) patients underwent upfront liver transplantation. Five-year event-free survival and overall survival rates were 69.2% ± 6.1% and 77.6% ± 5.5% respectively. Among the 16 patients with relapse/progression, 9 had intrahepatic failure only, 5 had distant failure only, and 2 had combined local and distant failure. Predictors of inferior outcome included advanced Evans staging, disease involving both lobes, rupture, low AFP, and suboptimal response to first-line chemotherapy. Assigned in 44 patients, PRETEXT staging, SIOPEL, and CHIC risk groups significantly predicted EFS and OS.
CONCLUSIONS: Although the consensus HB/HCC 1996 protocol led to cure in three-quarters of pediatric HB patients, an upfront risk stratification system is required to identify and improve the outcome of high-risk patients.
