Childhood primary hepatocellular carcinoma and hepatitis B virus infection
Cancer, 1990
In the 7-year period between 1980 and 1987, six cases of childhood primary hepatocellular carcinoma (PHC) were confirmed histologically in our institution. Hepatitis B surface antigen (HBsAg) seropositivity was confirmed in five of the cases, and tissue HBsAg was shown in four of these using the Shikata's orcein stain. An associated maternal HBsAg seropositivity was shown in two of the seropositive children. The youngest seropositive patient who developed PHC was 7 years old. The mother of this patient was also seropositive. These observations support a causal relation between childhood Hepatitis B virus infection and PHC. The importance of vertical or perinatal transmission of HBV in the causation of childhood PHC and the prophylactic role of childhood vaccination is emphasized. Attention is also drawn to the relative short malignant transformation time seen in some of these patients.
Primary hepatocellular carcinoma and hepatitis B infection during childhood

Twenty pediatric patients with primary hepatocellular carcinoma in Taiwan were tested for HBsAg, and all were found to be positive. The youngest case was 8 months of age, five cases occurred between 9 and 10 years of age, and 14 cases occurred between 11 and 16 years of age. The serum a-fetoprotein was elevated in all 20 primary hepatocellular carcinoma patients, and the average survival of these cases after diagnosis was 4.7 months. Seventy per cent of the mothers of the pediatric primary hepatocellular carcinoma cases and 62.9% of their MATERIALS AND METHODS From January, 1974 to June, 1985, 20 patients with PHC were admitted to the Department of Pediatrics, Veterans General Hospital, Taipei, Taiwan. Twelve were males and eight were females, and their ages ranged from 8 months to 16 years.
Hepatocellular Carcinoma in an Infant due to Hepatitis B Virus Vertical Transmission

Hepatocellular carcinoma (HCC) is one of the common tumors in the world. The incidence of HCC generally increases with age in all population but there is a tendency of decreasing incidence in the elderly and it is very rare in children. This is a case report of HCC in a 9-month-old boy, who was admitted to the hospital with palpable abdominal mass in the right upper quadrant. Imaging modality by ultrasonography could not adequately demonstrate definite findings demonstrating that the tumor was derived from liver, and the diagnosis was neuroblastoma. Intra-operatively, the tumor mass appeared to be derived from the surface of the posterior edge of the liver, so it was a pedunculated tumor. The histopathological examination revealed a pedunculatedhepatocellular carcinoma grade 3. The Victorian blue staining and immunohistochemical staining were done afterward, which showed HBsAg positive result as found in non-tumor lesion as well as inneoplastic lesion of liver tissue.

Integrated hepatitis B virus (HBV) DNA sequences were found in neoplastic liver tissue of a hepatitis B surface antigen (HBsAg)-negative child who had previously suffered from HBsAg-positive chronic active hepatitis and was anti-HBs and antihepatitis B core (HBc) positive at the time of tumor development. Reintegration pattern was consistent with the presence of a single integration site of the HBV genome into cellular DNA, and clonal proliferation of such infected cells. A normal liver, tested in the same experiment with the same amount of total DNA, was negative for viral DNA sequences.

Background/Aims: Familial clustering of hepatitis B virus (HBV) infection is related to perinatal transmission, and is the main cause of familial-type hepatocellular carcinoma (HCC). The route of HBV transmission differs between the children and siblings of patients with HCC. This study examined the differences in HBV carrier rates and HCC-related mortality between two generations in HCC families. Methods: From 1992 to 1997, relatives of individuals with HCC were screened prospectively with ultrasonography, alpha-fetoprotein, liver biochemistry tests and viral markers. Total HCC-related deaths during a 9-year period were compared between the generations of index patients and their children. Results: The study included a total of 13 676 relatives in two generations. More HCC-related deaths occurred in the index patient generation than in the child generation. Furthermore, children of female index patients had higher rates of liver cancer related mortality than children of male index patients. The same was true when the analysis was limited to male HBV carriers. The prevalence of HBsAg in the offspring of HBsAg positive mothers was 66% in the child generation and 72% in the index patient generation. These high prevalences indicated high maternal HBV replication status. Conclusions: Perinatal transmission and maternal viral load are important risk factors in hepatocarcinogenesis.

Alaska Native people experience the highest rates of acute and chronic hepatitis B virus (HBV) infection and hepatocellular carcinoma (HCC) in the United States. We examined the effect of a universal newborn immunization with hepatitis B vaccine and mass population screening immunization program initiated in 1984 on rates of HBV and HCC in children 25 years later. During this time, the population of Alaska Native people grew from an estimated 75,000 to 130,000 persons. A surveillance system to detect acute HBV infection in Alaska Native facilities was established in 1981. Cases of HCC in children under 20 years of age were identified using a National Cancer Institute (NCI)-funded Cancer Registry established in 1969 coupled with an active surveillance program of screening persons with chronic HBV semiannually for alpha-fetoprotein since 1982. The incidence of acute symptomatic HBV infection in persons <20 years of age fell from cases 19/100,000 in 1981-1982 to 0/100,000 in 1993-19...
Background: Hepatocellular carcinoma in children with hepatitis B virus infection is rarely reported. Metastases to the vertebrae are an even more unusual phenomenon. Case presentation: We report on a case of a 10-year-old Ethiopian boy with hepatitis B infection presenting with paraplegia and incontinence of 10 days' duration. A diagnosis of hepatocellular carcinoma with vertebral metastases was confirmed with serum α-fetoprotein, fine-needle aspirate cytology, and abdominal imaging. Conclusion: Surveillance of children not immunized against hepatitis B virus prevents infection and its complications, such as hepatocellular carcinoma. Among children in endemic countries prone to development of hepatocellular carcinoma, metastatic disease can present as sudden weakness of extremities with radiologic findings of vertebral body collapse.
