Abstract
The primary epithelial tumors of the liver (PETL) are composed of a series of heterogeneous tumors. Although the classification of PETLs has been updated several times by the World Health Organization, the cellular origins of some tumors in this family remain to be precisely depicted. In addition, certain tumors in different categories have similar histology, molecular phenotypes and biological characteristics, suggesting that they may have the same cellular origin. In this work, a narrative review method was adopted to review the relevant papers. By comparing the expression profiles of biomarkers of liver epithelium at different lineages and stages of differentiation, the cells-of-origin of some major members of the PETL family were reassessed. We propose that 1) hepatic adenomas, hepatocellular carcinomas (HCCs) and pure fetal hepatoblastomas (HBs) share the same spectrum in their cellular origin including the hepatocytic-committed progenitors (HCP) and their differentiated descendants. 2) Bile duct adenomas, peribiliary cysts and intrahepatic cholangiocellular carcinomas (ICCs) can share the same spectrum in their cellular origin including the cholangiocytic-committed progenitors (CCP) and their differentiated descendants. 3) The cells-of-origin of embryonal HBs include liver stem cells (LSCs), hepatoblasts, and transitional cells between them. Embryonal HB with small cell element, small cell undifferentiated HB and small cell neuroendocrine carcinoma of the liver can have the same or similar cells-of-origin from LSC. Embryonal HB lacking the small cell component of the LSC phenotype and presenting both hepatocytic and bile duct/ductule components may originate from actual hepatoblasts/hepatic progenitor cells (HPCs) as the combined HCC-ICC does. 4) Teratoid hepatoblastoma and mixed epithelial/mesenchymal HBs can be derived from the LSCs or even less committed extrahepatic pluripotent stem cell. 5) Many members of the PETLs family, including those derived from LSCs, hepatoblasts/HPCs, early HCPs and CCPs, have neuroendocrine potentiality. Except for those primary hepatic neuroendocrine tumor (PHNET) exhibit hepatocytic and/or cholangiocytic phenotypes, other PHNETs subtype may be derived from the descendants of LSC that differentiate towards the upper digestive tract, pancreas or other lineages.

Abstract
BACKGROUND Infantile hepatic hemangioendothelioma (IHH) and hepatoblastoma (HBL) are respectively the most common benign and malignant liver tumors in children. OBJECTIVES To study the clinical manifestations and the ultrasound features of the pediatric patients for distinguishing IHH from HBL. PATIENTS AND METHODS Between 2002 and 2012, thirteen children with IHH and 38 children with HBL under the age of 10 years were included. We retrospectively reviewed the clinical and the ultrasound features of the two groups, especially including parameters as follows: age at diagnosis, gender, alpha-fetoprotein (AFP) elevation, venous involvement and Doppler ultrasound. RESULTS Compared with HBL group, the age of IHH group was much younger (5.8 months vs. 35.1 months, P = 0.000), the AFP elevation was less likely to be detected in IHH group (23.1% vs. 89.5%, P = 0.000). Although the color flow were the same commonly observed (61.5% vs. 52.6%, P > 0.05), the spectral Doppler showed IHH was less likely to appear as arterial flow with resistance index (RI) > 0.7(12.5% vs. 75.0%, P < 0.05), characterized by arterial flow with RI < 0.7 and/or venous flow. Combined the clinical features including age (< 6 months) and normal AFP level yielded high capability in differential diagnosis, with sensitivity, specificity and Youden index of 77% (10/13), 95% (36/38), and 0.72, respectively. When combined clinical features (age and AFP) and spectral Doppler as the diagnostic criterion for distinguishing these cases with positive color flow signals, the sensitivity, specificity, accuracy and Youden Index were 88%, 95%, 89% and 0.83, respectively. CONCLUSIONS The clinical features are effective indicators for distinguishing IHH from HBL, and the spectral Doppler may be a useful adjunct parameter for differential diagnosis.

Abstract
Hepatoblastoma (HBL) is a rare primary malignant liver tumor affecting mainly pediatric patients in the age group 6 months to 3 years. Presentation of HBL in the neonatal period is rare. HBL can be diagnosed on cytology along with subtyping. Estimation of serum alpha-fetoprotein (AFP) is essential as a tumor marker. Fetal type HBL usually shows high AFP level. In this report, diagnosis of HBL in a 10-day-old baby with low serum AFP is being described for its unusual presentation.

Abstract
PURPOSE Children with pure fetal histology (PFH) hepatoblastoma treated with complete surgical resection and minimal adjuvant therapy have been shown to have excellent outcomes when compared with other patients with hepatoblastoma. We prospectively studied the safety and efficacy of reducing therapy in all children with stage I PFH enrolled onto two consecutive studies. PATIENTS AND METHODS From August 1989 to December 1992, 9 children with stage I PFH were treated on the Intergroup Hepatoblastoma study INT-0098 and were nonrandomly assigned to receive chemotherapy after surgical resection with single-agent bolus doxorubicin for 3 consecutive days. From March 1999 to November 2006, 16 children with stage I PFH enrolled onto Children's Oncology Group Study P9645 were treated with observation after resection. Central confirmation of the histologic diagnosis by a study group pathologist was mandated. The extent of liver disease was assigned retrospectively according to the pretreatment extent of disease (PRETEXT) system and is designated "retro-PRETEXT" to clarify the retrospective group assignment. RESULTS Five-year event-free and overall survival for the 9 patients treated on INT-0098 were 100%. All 16 patients enrolled onto the P9645 study were alive and free of disease at the time of last contact, with a median follow-up of 4.9 years. Retro-PRETEXT for the 21 patients with available data revealed seven patients with stage I disease, 10 patients with stage II disease, and four patients with stage III disease. CONCLUSION Children with completely resected PFH hepatoblastoma can achieve long-term survival without additional chemotherapy. When feasible, surgical resection of hepatoblastoma at diagnosis, without chemotherapy, can identify children for whom no additional therapy is necessary.

Abstract
We evaluated clinical significance of serum alpha-fetoprotein (AFP)-IgM immune complexes, in comparison with free AFP, on the diagnosis of primary hepatocellular carcinoma (HCC). Serum levels of AFP-IgM immune complexes and free AFP were determined by the ELISA method and electrochemiluminescence, respectively, in 103 healthy controls, 74 patients suffering from primary HCC, 27 patients suffering from liver cirrhosis, and 63 patients suffering from chronic hepatitis. The best cut-off value of AFP-IgM and free AFP for diagnosis of primary HCC were 300 AU/mL and 10 microg/L respectively, according to the area under the curve (AUC) in this study. The sensitivity of AFP-IgM and free AFP were 64.9 and 79.7%, and the specificity were 75.6 and 80.3%, respectively, when all cases of primary HCC were analyzed, and the AUC of free AFP was larger than that of AFP-IgM (0.85 vs. 0.72, Z=3.21). However, in case of primary HCC at early stages (stages I and II) were analyzed, the AUC of AFP-IgM was larger than that of free AFP (0.91 vs. 0.82, Z=1.73), which demonstrated that the sensitivity of AFP-IgM and free AFP were 94.4 and 72.2%, and the specificity were 81.9 and 79.9%, respectively. When both AFP-IgM and free AFP were positive, the specificity of diagnosis of primary HCC was 89.1%, and the efficacy was 79.0%. It is concluded that either sensitivity or specificity of serum level of AFP-IgM immune complexes was higher than that of free AFP in the diagnosis of primary HCC at early stages. As there was false positive AFP-IgM existed in the patients suffering from cirrhosis and chronic hepatitis, the combination of free AFP and AFP-IgM could significantly increase specificity and decrease false negative and/or false positive in the primary HCC at early stages.

Abstract
PURPOSE It is generally accepted that postoperative chemotherapy does not affect the serum alpha-fetoprotein (AFP) level. The authors report on 3 patients who supposedly showed chemotherapy-related changes in their AFP levels after operation. METHODS This study included 3 patients with hepatoblastoma (1 case of PRETEXT III and 2 cases of PRETEXT IV). RESULTS One patient with PRETEXT III underwent a complete tumor resection, and the postoperative AFP level decreased until it reached the normal range. However, he consistently exhibited a transient, 2- to 3-fold increase in the AFP after each course of chemotherapy for 3 courses. The chemotherapy regimen had to be stopped because of drug-induced encephalopathy, but he has been followed up for 5 years without any evidence of recurrence, and his AFP level has also remained stable and in the normal range. Two patients with PRETEXT IV, who underwent a curative tumor resection, also showed similar chemotherapy-related changes in AFP levels. Both of these cases were observed only after the administration of routine postoperative chemotherapy instead of administering further high-dose chemotherapy. The AFP level remained stable for 17 months and 7 months after the cessation of chemotherapy in 2 cases, respectively. CONCLUSIONS Regarding the postoperative chemotherapy of hepatoblastoma, we have to pay close attention to both the AFP status during chemotherapy as well as the absolute AFP level.

Abstract
Hepatoblastoma (HB) and biliary atresia (BA) are both rare conditions that occurred in the patient described. This is the second such case in the literature. An explanation for this apparent coincidence could possibly be found in the existance of pluripotent liver stem cells. In humans, small epithelial cells (SEC) behave as pluripotent stem cells. These are cells that can develop as biliary epithelial cells or as liver parenchymal cells, and are thought to be the precursor cell of HB. They are present in a much higher concentration in the livers of patients with BA, which may make them prone to develop HB.
