BACKGROUND It is a challenge to identify patients who, after undergoing potentially curative treatment for hepatocellular carcinoma, are at greatest risk for recurrence. Such high-risk patients could receive novel interventional measures. An obstacle to the development of genome-based predictors of outcome in patients with hepatocellular carcinoma has been(More)
Hepatocellular carcinoma (HCC) is a highly heterogeneous disease, and prior attempts to develop genomic-based classification for HCC have yielded highly divergent results, indicating difficulty in identifying unified molecular anatomy. We performed a meta-analysis of gene expression profiles in data sets from eight independent patient cohorts across the(More)
The pancreatic fistula rate following distal pancreatectomy ranges widely, from 13.3 to 64.0 %. The optimal closure method of the pancreatic remnant remains controversial, especially regarding whether to use a stapler. All patients who underwent distal pancreatectomy in five Japanese hospitals from January 2001 to June 2009 were included in this study. All(More)
Hepatitis C virus (HCV) infection produces chronic hepatitis, cirrhosis, and, ultimately, hepatocellular carcinoma (HCC). A molecular analysis of the damaged liver tissues infected with HCV may identify specific gene-expression profiles associated with a risk for liver carcinogenesis. Forty patients with HCV-positive HCC were classified into two groups:(More)
BACKGROUND Cost-effectiveness of radiofrequency ablation (RFA) was assessed in treatment of hepatocellular carcinoma (HCC). PATIENTS AND METHODS During 5 years, 153 patients with HCC of 3cm or less received RFA, and 60 underwent surgery. Judgment after RFA therapy was classified into three grades: residual tumor (grade 1), necrotic area with a less safety(More)
Histopathological changes of biopsied pancreata were examined in three diabetic patients with autoimmune chronic pancreatitis (ACP). We found intra- and periinsular mononuclear cell (MNC)-mainly CD8+ T cell-infiltration as well as MNC infiltration around the ductal cells. Islet beta cell volume decreased significantly. Some ductal cells expressed insulin(More)
BACKGROUND/AIMS Lymph node metastases are common at autopsy; being found in 28% of autopsy cases of hepatocellular carcinoma have lymph nodes metastases. However, effective treatment for metastatic lymph nodes has not yet been established. METHODOLOGY We resected lymph node metastases in 8 out of 10 hepatocellular carcinoma patients. We assessed the(More)
A study was made of diabetic retinopathy in acromegaly. 10 of 15 patients with acromegaly had diabetes mellitus, and 3 of the 10 showed diabetic retinopathy. 2 of them had a diabetic family history. 1 patient with a diabetic family history had retinopathy of state IIIa in Scott's classification, and the other 2 showed a few microaneurysms and/or punctate(More)
Genetic deficiency of the glycogen-debranching enzyme (debrancher) causes glycogen storage disease type III (GSD III), which is divided into two subtypes: IIIa and IIIb. In GSD IIIb, glycogen accumulates only in the liver, whereas both liver and muscles are involved in GSD IIIa. The molecular basis for the differences between the two subtypes has not been(More)
A 63-year-old man with a history of acute coronary syndrome presented with anterior chest pain that had lasted more than 3 months. During treatment for acute myocardial infarction on admission, computed tomography (CT) was performed incidentally, revealing an anterior mediastinal tumor 28 mm in diameter. CT findings after 3 months demonstrated an anterior(More)
