Hepatoblastoma is the most common pediatric liver malignancy and usually occurs within the first 3 years of life. In recent years, the overall incidence of hepatoblastoma has exhibited the greatest increase among all pediatric malignancies worldwide. The diagnosis of hepatoblastoma may be challenging due to the lack of a current consensus classification system. The International Pediatric Liver Tumors Consensus introduced guidelines and a consensus classification for the diagnosis of hepatoblastoma as either epithelial or mixed epithelial and mesenchymal and in the updated 5th edition of the World Health Organization Classification of Digestive System Tumors.

Hepatocellular carcinoma (HCC) is heterogeneous in pathogenesis, phenotype and biological behavior. Various histopathological features of HCC had been sporadically described, and with the identification of common molecular alterations of HCC and its genomic landscape over the last decade, morpho-molecular correlation of HCC has become possible. As a result, up to 35% of HCCs can now be classified into histopathological variants, many of which have unique molecular characteristics. This review will provide an introduction to the variously described histopathological variants of HCC in the updated WHO Classification of Digestive System Tumors.

Transarterial chemoembolization (TACE) is recommended as the first line treatment option
for the patients with Barcelona Clinic Liver Cancer (BCLC) stage B hepatocellular carcinoma
(HCC), however, treatment strategy and evaluation of effects after TACE has not been fully
established. Recently, sub-stage of BCLC stage B has been proposed and validated, but it
should be validated including a large number of the patients and its refinement should be
discussed. We have validated the sub-stage of BCLC stage B (B1-B4) by comparing overall
survival after TACE, and there was no statistically significant difference in overall survival
after TACE between B1 and B2. After excluding the patients with Child-Pugh point 7 from B1,
the overall survival was significantly better than that of B2. Therefore, up-to-seven criteria is
shown to be a reliable tool for the treatment strategy in the patients with intermediate stage
of HCC. Refinement of sub-stage of BCLC stage B has been proposed by some other institutes,
and it is important to establish novel treatment strategy for the patients with BCLC stage B
after TACE to improve the prognosis of the patients after TACE, and to define the best timing
for conversion to sorafenib or liver transplantation should be discussed. (J Liver Cancer

Hepatocellular carcinoma (HCC) shows a poor prognosis with high recurrence rate even after
surgical resection. To improve prognosis of HCC patient, regular surveillance for high-risk
group is recommended, but cost-benefit of the surveillance under 40 years old Asian male
with hepatitis B infection is unclear. We share a 39-year-old male case which showed early
recurrence and rapid extrahepatic metastasis after surgical resection for single huge HCC.
Based on the pathologic finding, this case was diagnosed with ‘stemness’-related markerexpressing
HCC. Further molecular classification for HCC could be beneficial to estimate
individual risk for HCC recurrence and to predict prognosis.
Background/Aims Hepatocellular carcinoma (HCC) with Barcelona Clinic Liver Cancer (BCLC)
intermediate stage includes a highly heterogeneous population. Here, we aimed to subclassify
hepatocellular carcinoma with BCLC intermediate stage for better prognostification. Methods Between 2003 and 2008, 325 patients who were newly diagnosed as HCC with
BCLC intermediate stage were considered eligible. Tumor factor and liver function were used
for sub-classification. Overall survival (OS) was analyzed using Kaplan-Meier method with a
comparison by log-rank test. Results A total of 325 patients with intermediate stage HCC were analyzed. Patients with
tumor size ≥7 cm, tumor number ≥4 and Child-Pugh class B had the worse OS compared
to those with tumor size <7 cm, tumor number <4 and Child-pugh class A, respectively (all
P<0.05). These three variables affected the OS independently from multivariate Cox regression
analysis (all P<0.05). So, using these three variables, patients were finally sub-classified as
those with fulfilling none of three factors (B-a), one of three factors (B-b), two of three factors
(B-c) and all of three factors (B-d) with the median OS of 39.2, 20.6, 12.0 and 8.3 months with
statistical significances (all P<0.05 between B-a and B-b, between B-b and B-c, and between
B-c and B-d), respectively. Conclusions Sub-classification of HCC with BCLC intermediate stage may be useful in not only
prognostification but also guidance of treatment strategies. (J Liver Cancer 2016;16:17-22)
