Popis: This was a retrospective analysis of liver transplant for pediatric patients with liver cirrhosis and hepatocellular carcinoma.Fourteen pediatric patients with chronic liver disease and hepatocellular carcinoma underwent liver transplant from 2004 to 2021. Preexisting diseases were tyrosinemia (n = 6), progressive familial intrahepatic cholestasis type 2 (n = 2) and type 3 (n = 3), cryptogenic cirrhosis (n = 2), hepatitis B and D (n = 1), and biliary atresia (n = 1).Mean age was 9.43 ± 4.9 years (range, 13 months to 16 years). Three patients had 1 tumor, 4 had 2 tumors, and 7 had multiple (≥3) lesions. Six patients were classified as Pretreatment Extent of Disease Staging System for Hepatoblastoma (PRETEXT) stage IV, 3 as stage II, and 5 as stage I. Some patients received systemic chemotherapy before (n = 4) or after transplant (n = 3) or transarterial chemoembolization and microwave ablation pretransplant (n = 1). Hepatocellular carcinoma posttransplant recurrence was observed at 23, 47, and 108 months in 3 patients (21%). Recurrence sites were omentum (n = 1) and liver graft (n = 2). One patient was treated with hepatic resection, radiofrequency ablation, and radiotherapy, while the other received radiofrequency ablation and chemotherapy for graft tumor recurrence. Relapse-free patient survival rates were 92%, 82.5%, and 72.2% at 2, 4, and 10 years, respectively. Four recipients (28.5%) died; posttransplant cause of death was infection at 19 (n = 1) and 188 months (n = 1) or hepatocellular carcinoma recurrence at 79 (n = 1) and 165 months (n = 1). Median follow-up was 178 months (range, 13-204 months). Mean estimated survival was 171.25 ± 16.6 months. Overall patient posttransplant survival was 100%, 92.3%, 92.3%, 83%, and 72% at 1, 2, 5, 10, and 15 years, respectively.Hepatocellular carcinoma was mainly associated with inherited liver diseases in our pediatric series. Liver transplant provided a long-term survival advantage to pediatric patients with preexisting cirrhosis and hepatocellular carcinoma.
