Esophageal squamous cell carcinoma (ESCC) is an important cause of cancer-related death worldwide. To improve prognoses in patients with ESCC, we evaluated the potential of transforming growth factor-beta-induced protein (TGFBI), which is overexpressed in ESCC, as a therapeutic candidate. We examined the clinical significance of TBFBI in 102 ESCC samples(More)
Barrett's esophagus (BE) is the premalignant lesion from which esophageal adenocarcinoma near the esophagogastric junction arises. The management of BE and the treatment of Barrett's esophageal adenocarcinoma (BEA) are important clinical issues in Europe and the United States. As the Helicobacter pylori infection rate in Japan is decreasing in the younger(More)
Software in a specific domain has several characteristics and each characteristic should be fixed when the software requirements are specified. In addition, these characteristics sometimes correlate with each other. However, we sometimes forget to specify several characteristics and/or to take their correlations into account during requirements elicitation.(More)
BACKGROUND Transcription factor prospero homeobox 1 (PROX1) has been identified as a master regulator of lymphangiogenesis associated with metastasis. Although PROX1 expression has been investigated in several cancers, its clinical significance remains controversial and needs further validation. In this study, we investigated the clinical and functional(More)
In a system development, the knowledge of a target business is very important factor for the success of a development. The needed part of such knowledge is different for each stakeholder. Therefore, we need a method to measure the level of understanding of a stakeholder and a method to categorize business knowledge. This paper proposes the metric of(More)
BACKGROUND/AIM The amino acid positron emission tomography (PET) tracer [(18)F]-3-fluoro-alpha-methyltyrosine ((18)F-FAMT) is known to be highly specific for malignancies. We evaluated the accumulation of (18)F-FDG or (18)F-FAMT in lymph nodes (LN) prior to definitive chemoradiotherapy (CRT) for esophageal cancer. PATIENTS AND METHODS We retrospectively(More)
AIMS L-[3-(18)F]-α-Methyltyrosine ((18)F-FAMT) has high specificity for malignant tumors on positron emission tomography (PET), and its role and potential usefulness has been previously investigated in operable esophageal carcinoma. We aimed to assess the ability of (18)F-FAMT PET to predict the response of esophageal cancer to definitive chemoradiotherapy.(More)
Endoscopic submucosal dissection (ESD) is a more difficult technique for esophageal cancer than for gastric cancer because the working space for esophageal ESD is small. Further, the difficulty level gradually increases depending on the size of the carcinoma. To overcome these difficulties, double endoscopic intraluminal operation (DEILO), which enables the(More)
We reviewed the indications for re-thoracotomy after esophagectomy for esophageal cancer. Hemothorax, chylothorax, tracheobronchial injury (fistula), pneumothorax, and pyothorax were the main causes of re-thoracotomy. Indications for emergency thoracotomy were as follows. 1)Hemothorax:bleeding through the chest drain continuing at >100 ml/hour for ≥5 hour,(More)
