Children with unresectable HCC have a dismal prognosis and few approved treatment options. TACE is an effective treatment option for adults with HCC, but experience in children is very limited. Retrospective analysis was performed of 8 patients aged 4-17 years (4 male, mean 12.5 years) who underwent TACE for unresectable HCC. Response to TACE was evaluated by change in AFP, RECIST and tumor volume, PRETEXT, and transplantation eligibility by UCSF and Milan criteria. Post-procedure mean follow-up was 8.2 years...

Focal nodular hyperplasia (FNH) is a benign hepatic tumor rarely seen in pediatric patients, with most cases reported in school-aged children with a history of malignancy, liver disease, chemotherapy, or hematopoietic stem cell therapy. Despite having advanced radiographic imaging, diagnosing FNH before surgical resection can be difficult. We report a rare case of pedunculated FNH presenting as a large abdominal mass palpated on physical exam in a healthy 3-year-old girl with no history of malignancy or underlying liver disease...

BACKGROUND: Understanding the celiac trunk and hepatic artery anatomy is important not only in preventing iatrogenic injuries but also in planning surgical procedures in children. Therefore, the aim of this study is to analyze the prevalence of celiac trunk (CeT) and common hepatic artery (CHA) variations in the pediatric population. MATERIALS AND METHODS: One hundred and seventy-four children (174) who underwent abdominal multidetector computed tomography (MDCT) angiography, either because of trauma or liver transplantation, were analyzed retrospectively...

BACKGROUND: Desmoplastic small round cell tumor (DSRCT) is an aggressive soft tissue sarcoma affecting children and young adults with 5-year overall survival (OS) of approximately 20%. Despite generally poor prognosis, long-term survival does occur. However, no evidence-based system exists to risk-stratify patients at diagnosis. METHODS: We retrospectively reviewed all DSRCT cases diagnosed at our institution between January 2000 and September 2016. Demographics, diagnostic imaging, and clinical data were reviewed...

REVIEW
Monika Vyas, Dhanpat Jain
The differential diagnosis of hepatic mass lesions is broad and arriving at the right diagnosis can be challenging, especially on needle biopsies. The differential diagnosis of liver tumors in children is different from adults and is beyond the scope of this review. In adults, the approach varies depending on the age, gender, and presence of background liver disease. The lesions can be divided broadly into primary and metastatic (secondary), and the primary lesions can be further divided into those of hepatocellular origin and nonhepatocellular origin...

INTRODUCTION: Non-alcoholic fatty liver disease is characterized by the intrahepatic deposition of fat. It is the most prevalent liver disease in the world, affecting obese children and adolescents. Its pathophysiology is not fully understood, although it is often related to insulin resistance. This in turn would be due to an inflammatory condition common to obesity. Thus, the objective of this study was to describe the behavior of proinflammatory cytokines in obese children and adolescents, with and without non-alcoholic fatty liver disease...

OBJECTIVE: Visceral adiposity index (VAI) is a mathematical model associated with cardiometabolic risk in adults, but studies on children failed to support this association. Our group has proposed a pediatric VAI model using pediatric ranges, but it has not yet been evaluated and needs further adjustments. The objective of this study was to further adjust the proposed pediatric VAI by age, creating a new pediatric metabolic index (PMI), and assess the correlation of the PMI with insulin resistance indexes and hepatic enzymes...

A characteristic shared by most frequent types of primary liver cancer, i.e., hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA) in adults, and in a lesser extent hepatoblastoma (HB) mainly in children, is their high refractoriness to chemotherapy. This is the result of synergic interactions among complex and diverse mechanisms of chemoresistance (MOC) in which more than 100 genes are involved. Pharmacological treatment, although it can be initially effective, frequently stimulates the expression of MOC genes, which results in the relapse of the tumor, usually with a more aggressive and less chemosensitive phenotype...

Juvenile xanthogranuloma (JX) is a benign growth of fibrohistiocytoma range that mainly affects children. The most frequent localization of the tumor is skin integument. Non-cutaneous forms of JX are found in 5-10% of cases; they are manifested as deep lesions of soft tissues, involvement of various organs (oropharynx, lungs, liver, spleen, pericardium, gastrointestinal tract, central nervous system, bone marrow) including the organ of vision. JX can develop in any part of the eye and its appendages. Taking into consideration how rare this pathology is, its diagnosis and treatment are complicated...

Hepatoblastoma (HB) is the most common malignant liver tumor in children. DNA and DNA-associated processes are one of the most important targets of chemotherapeutic agents. Isoorientin (Iso), a natural flavonoid compound, can be extracted from several plant species. The effects of Iso and its molecular mechanisms on hepatic malignancies remain unclear. Herein, the anti-tumor effects of Iso in HB and its underlying mechanisms were explored. We found that Iso significantly inhibited the proliferation of HB cells both in vitro and in vivo...

OBJECTIVE: Myocarditis is an important cause for cardiovascular morbidity and mortality in children and adults. The lncRNA taurine up-regulated gene 1 (TUG1) plays important roles in cell apoptosis and inflammation in tumor and liver injury. The present study aimed to investigate the role of TUG1 in LPS-injured H9c2 cells and explore the underlying molecular mechanism. METHODS: H9c2 cells were stimulated with LPS to induce inflammatory injury. The expression of TUG1 was altered by transient transfections...

A 37-year-old male, who at the age of 8 years had been treated for right-sided Wilms' tumor with nephrectomy, radiotherapy, and chemotherapy, presented with noncirrhotic portal hypertension (NCPH), grade 2 esophageal varices, and ascites. A CT scan demonstrated hypoplasia of liver segments 2 and 3. A liver biopsy showed portal tract fibrosis without cirrhosis, with histological features of NCPH. Liver vein catheterization showed a normal portal pressure gradient of 5 mm Hg while spleen to hepatic vein pressure was 29 mm Hg...

Chronic Hepatitis B Virus (HBV) infection is linked to hepatocellular carcinoma (HCC) pathogenesis. Despite the availability of a HBV vaccine, current treatments for HCC are inadequate. Globally, 257 million people are chronic HBV carriers, and children born from HBV-infected mothers become chronic carriers, destined to develop liver cancer. Thus, new therapeutic approaches are needed to target essential pathways involved in HCC pathogenesis. Accumulating evidence supports existence of hepatic cancer stem cells (hCSCs), which contribute to chemotherapy resistance and cancer recurrence after treatment or surgery...

A 3-year-old Japanese girl treated for hypoplastic left heart syndrome and Dandy-Walker syndrome was diagnosed with Kabuki syndrome (KS) with a mutation of KMT2D; c.13285C>T:p.Q4429*. Concurrently, macrohematuria portended the diagnosis of Wilms tumor. Postoperative chemotherapy has achieved complete remission despite a prolonged and reduced regimen due to liver dysfunction and convulsions. Cancer predisposition has been suggested for KS due to oncogenic mutations in KMT2D or KDM6A. The first case of nephroblastoma exemplified the treatability of malignancies in KS patients, as shown in the 9 cases reviewed...

BACKGROUND: Adult Wilms tumor (WT, nephroblastoma) is a rare, but well-described renal neoplasm. Although inferior vena cava tumor thrombosis is present in up to 10% of Wilms tumors in childhood, only few cases of this clinical manifestation in adults have been reported. To the best of our knowledge, this is the first case of adult WT infiltrating into inferior vena cava (IVC) with concomitant distal deep vein thrombosis. CASE PRESENTATION: A 28-year-old male patient with gross hematuria and right flank pain was diagnosed with right kidney tumor penetrating to IVC...

Hepatoblastoma is the most common primary liver tumor for children aged <5 years old. 20(S)-Protopanaxadiol (PPD) is a ginsenoside extracted from Pananx quinquefolium L ., which inhibits tumor growth in several cancer cell lines. The purpose of the present study was to assess the anticancer activities of 20(S)-PPD in human hepatoblastoma HepG2 cells. The cytotoxicity of 20(S)-PPD on HepG2 cells was evaluated using an MTT assay. Apoptosis was detected using DAPI staining and flow cytometry. The expression of apoptosis-associated proteins was identified by western blotting...

Imaging is crucial in the assessment of children with a primary hepatic malignancy. Since its inception in 1992, the PRETEXT (PRE-Treatment EXTent of tumor) system has become the primary method of risk stratification for hepatoblastoma and pediatric hepatocellular carcinoma in numerous cooperative group trials across the world. The PRETEXT system is made of two components: the PRETEXT group and the annotation factors. The PRETEXT group describes the extent of tumor within the liver while the annotation factors help to describe associated features such as vascular involvement (either portal vein or hepatic vein/inferior vena cava), extrahepatic disease, multifocality, tumor rupture and metastatic disease (to both the lungs and lymph nodes)...

Adult hepatoblastoma (AHB) is a rare liver tumor with a poor prognosis in adolescents and adults. This contrasts with hepatoblastoma in children and is not fully understood. Here we describe two adolescents with AHB who were treated in our hospital. Adolescents are likely to receive less intensive chemotherapy protocols and are treated in hospitals with less experience in pediatric oncology, resulting in poor outcome. More research is necessary for optimal treatment of AHB in adolescents. Adolescents with AHB should be referred to hospitals experienced in pediatric oncology and receive intensive chemotherapy, followed by hemihepatectomy...
