treatment, thereby reducing the difference in treatment results among different institutions; (3) to reduce unnecessary costs and efforts; (4) help enable people to undergo treatment without anxiety. These guidelines provide only guidance on the indications for treatment and do not restrict or prohibit the use of any treatment deviating from those described(More)
Many publications focusing on the background or original mucosa of Barrett adenocarcinoma have maintained that adenocarcinoma arises in intestinal-type mucosa with goblet cells in the columnar-lined esophagus, and this has become a central dogma. The mucosa on each side of a series of 141 minute esophageal adenocarcinomas (almost all of which were mucosal(More)
Amino acids, especially branched-chain amino acids such as l-leucine, have been shown to regulate activation of p70 S6 kinase and phosphorylation of 4E-BP1 through the mTOR signaling pathway. In our recent study, l-arginine was also shown to activate the mTOR signaling pathway in rat intestinal epithelial cells. l-Glutamine is an amino acid that is required(More)
Amino acids, especially branched-chain amino acids such as l-Leucine, have been revealed to regulate activation of p70 S6 kinase and phosphorylation of 4E-BP1 through mTOR signaling pathway. In this study, we showed that a cationic amino acid, l-Arginine, also activated this signaling pathway in a rapamycin-sensitive manner in rat intestinal epithelial(More)
p53 protein accumulation, thought to be caused by p53 gene mutation, is closely related to poor prognosis of patients with certain types of carcinomas. The progression of esophageal squamous cell carcinoma (SCC) is also strongly suspected to depend on the p53 tumor suppressor gene. Formalin-fixed, paraffin-embedded sections were taken from 25 patients who(More)
Focal adhesion kinase (FAK) is often up-regulated in a variety of malignancies, including gastrointestinal stromal tumor (GIST), and its overexpression seems to be associated with tumor progressiveness and poor prognosis. GIST is well known to have a mutation to c-KIT; thus, a specific c-KIT inhibitor (imatinib) is recognized as the first-line chemotherapy(More)
We report seven early gastric cancers in five patients, which arose in the reconstructed gastric tube after radical resection for esophageal cancer. Four of them occurred in the middle gastric tube and three in the distal gastric tube. Three of 5 cases were reconstructed via the retromediastinal route and two via the presternal route. They all were(More)
AIMS We evaluated the techniques of colonic interposition and supercharge for esophageal reconstruction and discussed the main considerations related to these procedures. PATIENTS AND METHODS In this study, we performed 51 esophageal reconstructions using colonic interposition. Twenty-eight of the 51 patients had synchronous or allochronic gastric(More)
MicroRNAs (miRNAs) are an abundant class of small noncoding RNAs that function as negative gene regulators. miRNA deregulation is involved in the initiation and progression of human cancer; however, the underlying mechanism and its contributions to genome-wide transcriptional changes in cancer are still largely unknown. We studied miRNA deregulation in(More)
Degradation of basement membrane and extracellular matrix structures are important features of the metastatic process of malignant tumors. Human heparanase degrades heparan sulfate proteoglycans, which represent the main components of basement membranes and the extracellular matrix. Because of the role of heparanase in tumor invasion and metastasis, we(More)
