Evaluation of surgical strategies and long-term outcomes in pediatric hepatocellular carcinoma

PurposeHepatocellular carcinoma (HCC), the second most common pediatric malignant liver tumor after hepatoblastoma, represents 1% of all pediatric tumors.MethodsA retrospective study was conducted on children with HCC treated at our center from March 2002 to October 2022, excluding those with inadequate follow-up or records. Demographic data, initial complaints, alpha-fetoprotein (AFP) values, underlying disease, size and histopathological features of the masses, chemotherapy, and long-term outcomes were analyzed.ResultsFifteen patients (8 boys, 7 girls) with a mean age of 11.4 +/- 4.1 years (0.8-16.4 years) were analyzed. The majority presented with abdominal pain, with a median AFP of 3.9 ng/mL. Hepatitis B cirrhosis in one patient (6.6%) and metabolic disease (tyrosinemia type 1) in two patients (13.3%) were the underlying diseases. Histopathological diagnoses were fibrolamellar HCC (n:8; 53.3%), HCC (n:6; 40%). Four of the 15 patients underwent liver transplantation, and 9 underwent surgical resection. Due to late diagnosis, two patients were considered inoperable (13.3%). The survival rate for the four patients who underwent liver transplantation was found to be 75%.ConclusionSurgical treatment of various variants of HCC can be safely performed in experienced centers with a multidisciplinary approach, and outcomes are better than in adults.
