Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related death worldwide. We sequenced and analyzed the whole genomes of 27 HCCs, 25 of which were associated with hepatitis B or C virus infections, including two sets of multicentric tumors. Although no common somatic mutations were identified in the multicentric tumor pairs, their(More)
BACKGROUND Endoscopic submucosal dissection (ESD) has been positively applied to and gradually standardized for early stomach cancer, particularly in Japan. However, because it is technically difficult to perform ESD of the colon, ESD is not a commonly used technique. OBJECTIVE The aim of this study was to evaluate the possibility of standardizing(More)
Alanine aminotransferase (ALT) elevations were the most frequent adverse events during all-oral combinations with daclatasvir and asunaprevir for patients with hepatitis C virus (HCV) infection, but the underline mechanisms are unclear. Seventy patients with chronic HCV genotype 1b infection, who were introduced daclatasvir 60 mg once daily plus asunaprevir(More)
The aim of this report is to review and evaluate, in a comprehensive manner, the published data regarding the contribution of genetic polymorphisms to risk of head and neck cancer (HNC). All relevant studies available in MEDLINE and published before July 2007 were identified. Studies carried out in humans that compared HNC patients with at least 1 standard(More)
BACKGROUND AND AIM Advanced glycation end products (AGE), senescent macroprotein derivatives formed at an accelerated rate in diabetes, play important roles in the pathogenesis of diabetic vascular complications. Recently, AGE have also been found to be involved in insulin resistance. Although non-alcoholic steatohepatitis (NASH) is generally considered a(More)
BACKGROUND In EMR of early gastric cancer (EGC), en bloc resection reduces the risk of residual cancer. Endoscopic submucosal dissection (ESD) now allows en bloc resection of large EGCs. OBJECTIVE To retrospectively determine whether ESD is more advantageous than EMR for EGCs. DESIGN EMR (825 lesions, 711 patients) or ESD (195 lesions, 185 patients) was(More)
BACKGROUND & AIMS Improved therapeutic options for chronic hepatitis C virus (HCV) infection are needed for patients who are poor candidates for treatment with current regimens due to anticipated intolerability or low likelihood of response. METHODS In this open-label, phase 2a study of Japanese patients with chronic HCV genotype 1b infection, 21 null(More)
BACKGROUND The prevalence of nonalcoholic fatty liver disease (NAFLD) has been increasing. This study aimed to assess the recent prevalence of NAFLD and to predict the prevalence of nonalcoholic steatohepatitis (NASH) with liver fibrosis using established scoring systems in the general population. METHODS A cross-sectional study was conducted among 8352(More)
Lung cancer is the most common cause of death from cancer worldwide, and its incidence is increasing in East Asian and Western countries. To identify genetic factors that modify the risk of lung adenocarcinoma, we conducted a genome-wide association study in a Japanese cohort, with replication in two independent studies in Japanese and Korean individuals,(More)
Chronic viral hepatitis is the most important risk factor for progression to hepatocellular carcinoma (HCC). To identify genetic risk factors for progression to HCC in individuals with chronic hepatitis C virus (HCV), we analyzed 467,538 SNPs in 212 Japanese individuals with chronic HCV with HCC and 765 individuals with chronic HCV without HCC. We(More)
