In the 17th Nationwide Follow-up Survey of Primary Liver Cancer in Japan, 18 213 individuals were newly registered as patients with primary liver cancer at 645 medical institutions over a period of 2 years (from 1 January 2002 to 31 December 2003). Of these patients, 94.2% had hepatocellular carcinoma (HCC) and 4.1% had intrahepatic cholangiocarcinoma(More)
The geographic distribution of hepatitis B virus (HBV) genotypes in Japan and its clinical relevance are poorly understood. We studied 731 Japanese patients with chronic HBV infection. HBV genotype was determined by the restriction fragment length polymorphism (RFLP) method after polymerase chain reaction (PCR). Of the 720 patients with positive PCR, 12(More)
BACKGROUND In Japan and South Korea, transarterial chemoembolisation (TACE) is an important locoregional treatment for patients with unresectable hepatocellular carcinoma (HCC). Sorafenib, a multikinase inhibitor, has been shown effective and safe in patients with advanced HCC. This phase III trial assessed the efficacy and safety of sorafenib in Japanese(More)
BACKGROUND & AIMS Despite abundant clinical evidence, the mechanisms by which hepatic iron overload develops in patients with hepatitis C virus (HCV)-associated chronic liver disease remain unknown. The aim of this study was to investigate how hepatic iron overload develops in the presence of HCV proteins. METHODS Male transgenic mice expressing the HCV(More)
Hepatic resection (HX), percutaneous ethanol injection (PEI), and transcatheter arterial embolization (TCAE) have all been used in the treatment of patients with small-sized hepatocellular carcinomas (HCCs). However, the indications for these therapeutic modalities remain unclear. Therefore, the first step to minimize the debate on these indications is to(More)
BACKGROUND & AIMS To elucidate the survival of the patients with unresectable hepatocellular carcinoma (HCC) who underwent transcatheter arterial lipiodol chemoembolization (TACE) and to analyze the factors affecting the survivals. METHODS During the last 8 years, a nationwide prospective cohort study was performed in 8510 patients with unresectable HCC(More)
BACKGROUND/AIMS The treatment of choice for HCC remains controversial. We evaluated the therapeutic impact of surgical resection, PEI, and RFA for HCC on outcomes. METHODS A database derived from a Japanese nationwide survey of 17,149 patients with HCC treated by resection, PEI, or RFA between 2000 and 2003 was used to identify 7185 patients with no more(More)
The Clinical Practice Guidelines for Hepatocellular Carcinoma (HCC), the first evidence-based guidelines for the treatment of HCC in Japan, were compiled by an expert panel supported by the Japanese Ministry of Health, Labour, and Welfare. This set of guidelines covers six research fields: prevention, diagnosis and surveillance, surgery, chemotherapy,(More)
Hepatitis C virus (HCV) has been reported to potentially replicate in peripheral blood mononuclear cells (PBMCs), but direct information on the pathogenic implication of HCV infection in PBMCs is still limited. To investigate this issue, we compared the complexity of HCV quasispecies in serum, PBMCs, and livers of 13 patients with type C chronic liver(More)
We have identified and characterized a novel member of the ankyrin-repeat family named 'molecule possessing ankyrin-repeats induced by lipopolysaccharide' (MAIL). The C-terminal portion of MAIL shared high sequence homology with the I kappa B family. Intraperitoneal injection of lipopolysaccharide (LPS) into mice rapidly (<0.5 h) induced MAIL mRNA in(More)
