Recently, several reports of extrahepatic hepatocellular carcinoma metastasis demonstrated by technetium- 99mTc-IDAs scan have shown that 99mTc-IDA s can be used to detect extrahepatic metastasis in hepatocellular carcinoma. We report here a case of hepatocellular carcinoma with pulmonary nodules that were demonstrated as metastasis in nature by the use of the 99mTc-DISIDA. The findings in this case and several reports reviewed here suggest that the 99mTc-DISIDA scan may be a useful diagnostic agent that can detect the extrahepatic metastasis of hepatocellular carcinoma and stage the disease. But more clinical study in needed to establish the position of 99mTc-DISIDA in the field of diagnosis of extrahepatic hepatocellular carcinoma.

This study was carried out for investigating antitumor effects of 5-fluorouracil(5-FU), methotrexate(MTX) and retinoic acid(RA) on hepatocellular carcinoma induced in Sprague-Dawley rat. Antitumor effects were examined a flow cytometric DNA distributions by flow cytometry and stuied ATP/Pi using nuclear magnetic resorance, and the enzymatic activity of thymidylate synthetase and dihydrofolate reductase as well as contents of total collagen and sialic acid were measured with spectrophotometer. In this study, S phase fraction, contents of sialic acid and total collagen were decreased in the induced hepatocellular carcinoma treated with 5-FU and MTX, and synergistic effects of anticancer drugs were exhibited in the hepatocellular carcinoma treated with 5-FU and MTX simultaneously, and the inhibition of thymidylate synthetic and dihydrofolate reductase activity were shown in the hepatocellular carcinoma treated with 5-FU, MTX, and 5-FU and MTX simultaneously. On the other hand, the ratio of ATP/Pi were increased in all groups except group treated with RA. The experimental results suggest that above method may be valuable for evaluating antitumor effect of anticancer drugs.

FGFR3 is a member of the fibroblast growth factor receptor family which interacts with fibroblast growth factors, setting in motion a cascade of downstream signals, ultimately influencing mitogenesis and differentiation. This particular family member binds acidic and basic fibroblast growth hormone and plays a role in bone development and maintenance. Accumulated evidence suggests that aberrant regulation of FGFR3 and genetic alterations are implicated in the development and progression of various cancers. Despite a high incidence of FGFR3 over-expression, no such investigation has been performed in hepatocellular carcinoma. Thus, we investigated genetic alterations of the FGFR3 gene in 73 cases of hepatocellular carcinoma by single-strand conformational polymorphism (SSCP) and sequencing. One silent mutation (A369A) was found in the extracellular domain of FGFR3, and one genetic alteration in the immunoglobulin-like III domain of FGFR3 appeared to be polymorphism. Taken together, we concluded that over-expression of FGFR3 in hepatocellular carcinoma is not associated with genetic alterations of FGFR3 gene, and we suggest that there could be another underlying mechanism of aberrant FGFR3 expression in hepatocellular carcinoma.

A captive male polar bear (Ursus maritimus) was found dead after a long-term anorexia at a Park Zoo in Republic of Korea. At necropsy, the liver lesion was prominent with hepatomegaly carrying a big mass and numerous small nodules in various sizes. The cut surface of the nodules was creamy white, firm, and solid with umbilicated appearance. Histologically, there was proliferation of hepatocellular neoplastic cells arranged in glandular-like (pseudoglandular) pattern and complete loss of hepatocellular arrangement. The immunoreactivity for neoplastic hepatocyte antigens was positive for hepatocyte paraffin 1, and negative for vimentin, cytokeratin 7 and 19, and carcinoembryonic antigen. Based on those diagnostic features, the neoplasia was diagnosed as hepatocellular carcinoma. To the author's knowledge, this is the first case report of hepatocellular carcinoma in the captive polar bear in Republic of Korea.

Background: Hepatocellular carcinoma (HCC) is the fifth most prevalent cancer and thirdly leading cause of cancer-related death worldwide. The estimated risk of hepatocellular carcinoma is 15 to 20 times as high among persons infected with HCV as it is among those who are not infected, with most of the excess risk limited to those with advanced hepatic fibrosis or cirrhosis. Glypican3 (GPC3) plays a key role in relation to signaling with growth factors, regulating the proliferative activity of cancer cells. Glutamine synthetase (GS) catalyzes the synthesis of glutamine from glutamate and ammonia in the mammalian liver. GS was suggested as a specific marker for tracing cell lineage relationships during hepatocarcinogenesis. In normal liver, GS expression is seen in pericentral hepatocytes, but not by midzonal or periportal hepatocytes. In HCC, strong and diffuse GS expression in seen in tumor cells. Results: Glypican3 immunopositvity was highly specific and sensitive indicator for hepatocellular carcinoma as well as glutamine synthetase which was found to be a sensitive and specific indicator for development of hepatocellular carcinoma when compared to cirrhosis, liver cell dyspalsia and metastatic carcinomas. Statistical analysis revealed a significant association between GPC3 and GS with tumor size (P=0.003, p=0.006, respectively). Diffuse staining significantly associated with large tumor size while, focal and mixed staining was detected more with small tumor size. Studying the relation with tumor grade also revealed significant association between diffuse GPC3 and GS staining with high tumor grade. Diffuse staining was detected in 91.7% and 100% respectively of poorly differentiated specimens and only in 33.3% and 22.2% of well differentiated specimens. Conclusions: While using GPC3 and GS to screen for premalignant hepatic lesions remains controversial, our data suggest that GPC3 and GS may be a reliable diagnostic immunomarkers to distinguish HCC from benign hepatocellular lesions. However, negative immunostaining should not exclude the diagnosis of HCC.

Purpose: Numerous studies have evaluated the association between XRCC1 Arg399Gln gene polymorphism and hepatocellular carcinoma risk in the Chinese Han population. However, the results have been inconsistent. We therefore here examined whether the XRCC1 Arg399Gln gene polymorphism confers hepatocellular carcinoma risk by conducting a meta-analysis. Methods: PubMed, Google scholar and China National Knowledge Infrastructure databases were searched for eligible articles in English and Chinese that were published before April 2012. Results: 6 studies involving 1,246 patients with hepatocellular carcinoma and 1,953 controls were included. The association between XRCC1 Arg399Gln gene polymorphism and hepatocellular carcinoma in the Chinese Han population was significant under GG vs AA (OR = 1.48, 95% CI = 1.13 to 1.94). Limiting the analysis to the studies with controls in the Hardy-Weinberg equilibrium, the results were persistent and robust. Conclusions: In the Chinese Han population, the XRCC1 Arg399Gln gene polymorphism is associated with an increased hepatocellular carcinoma risk.

Hepatocellular carcinoma is one of the most common cancers worldwide. Extrahepatic metastasis commonly occur in the lung, lymph, nodes, bone, and adrenal glands. On the other hand, a metastasis of hepatocellular carcinoma to the skeletal muscle is rare. A 42-year-old woman presented for evaluation of a palpable mass with tenderness in her right thigh area. She has been diagnosed with hepatocellular carcinoma and pulmonary metastasis seven years ago and has received treatment. We performed incisional biopsy with suspicion of hepatocellular carcinoma metastasis from imaging studies and blood test results. The patient was finally diagnosed with metastasis of hepatocellular carcinoma in the semimembranosus muscle and treated by extensive resection. We report this case with a review of the relevant literature.

Objectives : Inchinohryungsan has been used for treatment of hepatobiliary diseases. This study was designed to investigate the effect of Inchinohryungsan pharmacopuncture on hepatocellular carcinoma in rats. Sprague Dawley(SD) rats of the control and experimental groups received intraperitoneal injection of 50 mg/kg DEN, weekly for 12 weeks. Methods : Rats were divided into 5 groups. Normal group was not induced hepatocellular carcinoma and not treated. Control group was induced hepatocellular carcinoma and injected with Inchinohryungsan pharmacopuncture into the root of tail. Experimental groups were induced hepatocellular carcinoma. BL group was injected with Inchinohryungsan pharmacopuncture into the $BL_{18}$ and $LR_{14}$, BG group was injected into the $BL_{19}$ and $GB_{24}$ and CSC group was injected into the $CV_{12}$, $ST_{25}$ and $CV_4$. Thereafter, the changes of the body weight, the liver weight and the weight of liver/100g body weight, WBC, neutrophil, lymphocyte and the activities of AST, ALT, ALP, LDH, AFP and SOD were measured. And gross anatomy, light and electron microscopy were performed. Results : The significant results were as follows, 1. The activities of LDH were significantly decreased in CSC group compared with control group. 2. The activities of AFP were significantly decreased in the BL, BG, CSC groups compared with control group. 3. The activities of SOD were increased in the BL, BG, CSC groups compared with control group and CSC group was significantly increased than normal group. 4. According to the gross anatomical observation, the control and BL, BG, CSC groups showed multi-nodular hepatocellular carcinoma. But the size and numbers of the hepatocellular carcinoma in experimental groups were smaller than control group. 5. The numbers of hepatic p53 positive cells were decreased in the BL, BG groups compared with control group. 6. According to the light and electron microscopical observation, the BL, BG and CSC groups were mildly improved than control group in morphological and histopathological changes. Conclusions : These results suggested that Inchinohryungsan pharmacopuncture may have some effects on hepatocellular carcinoma induced by DEN in rats.

Purpose: The purpose of this study was to examine the relationship among family support, self-care and quality of life(QOL) in Patients with hepatocellular carcinoma receiving transarterial chemoembolization, including the effects of these variables on QOL. Methods: The research was a cross-sectional, descriptive design. Participants were 103 patients with hepatocellular carcinoma who were receiving transarterial chemoembolization. Data were analyzed using descriptive statistics, t-test, one way ANOVA, and hierachial multiple regression analysis with SPSS 18.0 program. Results: QOL had a significant correlation with family support(r=.60, p<.001) and self-care(r=.38, p<.001). Family support had a significant correlation with self-care(r=.41, p<.001). Hierarchial multiple regression analysis for QOL revealed that the most powerful predictor was family support followed by self-care. Family support, self-care, gender, and occupation explained 50% of the variance in quality of life. Conclusion: These results indicate that various factors are related to the quality of life of these patients. Further, nursing strategies to improve the family support and self-care of patients with hepatocellular carcinoma are needed.

Majority of hepatocellular carcinoma is evolved from a well differentiated cancerous condition such as hyperplastic lesions eg. adenomatous hyperplasia in cirrhotic liver or de no vo carcinogenesis and prolifenation along with dedifferentiation. Adenomatous hyperplasia is may be seen in severe acute hepatic injury, like submassive hepatic necrosis, or in chronic liver diseases, particularly liver cirrhosis and it has recently attracted much interest from both clinicians and pathologists because it is regarded as a precursor lesion of hepatocellular carcinoma. Hepatic adenomatous hyperplasia resembling focal nodular hyperplasia might have developed from localized vascular changes associated with chronic liver disease, pre-existing arterial malformation and early stage of angiogenesis in hepatocarcinogenesis. We present a patient who developed hepatocellular carcinoma after hepatic artery ligation.
