Our previous study showed that male hepatocellular carcinoma (HCC) patients below 40 years of age had the worst survival in the initial several years, but had the best prognosis thereafter. Thus, it seems that age has a paradoxical influence on the prognosis. To further clarify the issue of age on HCC prognosis, we initiated this study. Methods: A total of 11 312 HCC cases from seven medical centers from 1986 to 2002 were included. We analyzed the 1-year survival and survival after 1 year. Results: Male gender, age younger than 40 years old and hepatitis B virus (HBV) were associated with worse 1-year survival. In contrast, male gender, age younger than 40 years old and HBV were associated with better survival after 1 year. Higher percentage of the young HCC patients had a tumor size larger than 3 cm. 83.7% of HCC patients below 40 years of age were male and 89.8% of them were HBV carriers. Conclusions: If we encountered a young HCC patient, the patient will probably be a male HBV carrier. He would probably have larger tumor and is more likely to expire within 1 year than the older HCC patients. However, if the young HCC patient can survive for more than 1 year, he would probably have better survival in the following years than the older patients. [ABSTRACT FROM AUTHOR]

Hepsin is a type II transmembrane protein predominantly expressed in the liver and has been implicated in participation in blood coagulation pathway and epithelial carcinogenesis. The aim of this current study is to investigate the role of hepsin in hepatocarcinogenesis. Methods: Quantitative real-time RT-PCR was used to investigate the expression levels of hepsin in a total of 50 paired hepatocellular carcinomas (HCCs) and the corresponding non-tumor liver tissues. Hepsin was transfected to the hepsin-non-expressing SK-HEP-1 cells to study the change of cell proliferation. Results: In 62% (31/50) patients, the expression levels of hepsin in non-tumor liver tissues are at least twofold higher than those in the corresponding HCC tissues. Positive hepatitis B surface antigen was more often detected in patients with hepsin underexpressed in the HCC tissues (74.2% vs. 31.6%, P=0.007). Patients with hepsin underexpressed in the HCC tissues survived shorter time than those without hepsin underexpression in the HCC tissues. The cell proliferation and for a colony formation of SK-HEP-1 HCC cells were inhibited by hepsin. Conclusions: Most HCC patients had hepsin underexpressed in the HCC tissues. These patients survived for a shorter time compared with those without hepsin underexpression in the HCC tissues. Hepsin expression could inhibit cell proliferation and colony formation of HCC cells.

The role of transcatheter arterial embolization in patients with resectable hepatocellular carcinoma: a nation-wide, multi-center study.Liver International 2004: DOI: 10.1111/j.1478-3231.2004.0941.x.© Blackwell Munksgaard 2004The role of transcatheter arterial embolization (TAE) for patients with resectable hepatocellular carcinoma (HCC) is controversial. Analyzing a cohort of nation-wide data can delineate the beneficial effect of TAE for those patients.From 1991 to 1995, 818 patients who had potentially resectable HCC from four medical centers in Taiwan were enrolled. Among them, 599 underwent curative resection, 157 received TAE and 62 received supportive treatment alone. The survivals among the three groups were compared.The 5-year survival rates for patients who underwent surgery, TAE and supportive treatment were 43.6%, 25.6% and 3.7%, respectively. Surgery offered the best survival for those patients. TAE could also prolong survival as compared with supportive treatment (P=0.0001). However, among patients who were in advanced tumor stage (Cancer and the Liver Italian Program (CLIP) score≥2), no statistical difference in survival was noted between patients who underwent TAE or supportive treatment. In multivariate analysis, single tumor, serum albumin≥3.5 g/dl, tumor size less than 5 cm, early-stage tumor (CLIP score=0–1) and aggressive treatment including surgery and TAE were independent factors associated with a better survival.Surgery is superior to TAE for patients with resectable HCC. In patients who refuse surgery, TAE can be considered for selected patients whose tumors are in early stage. [ABSTRACT FROM AUTHOR]
