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)
BACKGROUND The purpose of the current study was to assess whether [18F]fluorodeoxyglucose positron emission tomography (FDG-PET) provides incremental value (e.g., additional information on lymph node involvement or the presence of distant metastases) compared with computed tomography (CT) in patients with esophageal carcinoma. METHODS The authors examined(More)
BACKGROUND Transforming growth factor-beta (TGF-beta) has antiproliferative effects in various cells, and inactivation of the TGF-beta signaling pathway contributes to tumor progression or development. Smad4, a tumor suppressor gene, is a central mediator in the signaling pathways of the TGF-beta superfamily. This study was undertaken to clarify the(More)
The association of microRNAs (miRs) with cancer progression has been established in many cancers including esophageal squamous cell carcinoma (ESCC). A public microarray database showed that the expression of miR-150 was lower in ESCC than in normal esophageal mucosa. Here, we focused on ZEB1, epithelial-mesenchymal-transition (EMT)-inducer, as a target(More)
BACKGROUND The role and potential value of positron emission tomography (PET) scanning in certain tumors has been widely investigated in recent years. The authors retrospectively assessed the performance of 18-F-fluorodeoxyglucose (FDG)-PET in the assessment of esophageal squamous cell carcinoma (SCC). METHODS The results using PET were compared with(More)
Tissue-engineered cartilage may be expected to serve as an alternative to autologous chondrocyte transplantation treatment. Several methods for producing cartilaginous tissue have been reported. In this study, we describe the production of scaffold-free stiff cartilaginous tissue of pig and human, using allogeneic serum and growth factors. The tissue was(More)
BACKGROUND Our aim was to determine whether minichromosome maintenance protein (MCM) 2 expression is useful in predicting tumor proliferation rates and outcome after therapy in patients undergoing surgery for esophageal squamous cell carcinoma (SCC). In addition, we evaluated whether the expression of this proliferation marker was correlated with that of(More)
We investigated whether Helicobacter pylori (HP) eradication increases the incidence of reflux esophagitis (RE) in patients with peptic ulcers. From 2001-2005 consecutive out patients with peptic ulcers and HP received eradication and were followed endoscopically. HP was cured in 119 and RE developed in 33 of the 153 patients. RE developed in 24 of the 119(More)
BACKGROUND After esophagectomy a swallowing abnormality is the predominant symptom for esophageal cancer. The aims of this study were to examine (i) oropharyngeal swallowing by comparing pre- and postoperative period, and (ii) the relationship between oropharyngeal swallowing and the alimentary reconstruction route after esophagectomy. PATIENTS AND(More)
BACKGROUND Karyopherin-alpha 2 (KPNA2) is a member of the importin alpha family and has recently been reported to play an important role in tumorigenesis and tumor progression. The aim of the current study was to elucidate the clinicopathological significance of immunohistochemical expression of KPNA2 in esophageal squamous cell carcinoma (ESCC). PATIENTS(More)
