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 Circulating vascular endothelial growth factor-C (VEGF-C) levels were measured in patients with esophageal cancer to assess the value of VEGF-C as a biomarker for predicting tumor recurrence. PATIENTS AND METHODS Preoperative serum samples were acquired from 80 patients and healthy volunteers who served as normal controls. VEGF-C levels were(More)
Esophageal carcinoma is one of the most lethal tumors, and identification of prognostic factors for patients with this disease is important. Propyl isomerase Pin1 is overexpressed in some human cancers and thought to be an important regulator of cyclinD1. However, the relationships between Pin1 expression and clinicopathologic features in patients with(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)
OBJECTIVE Several studies reported that the levels of proinflammatory cytokines such as TNF-alpha, IL-1beta, IL-6, and IL-8 are elevated in the cerebrospinal fluid (CSF) of patients after subarachnoid hemorrhage (SAH). Cytokines in CSF may contribute to the development of vasospasm and cerebral ischemia. In the present study, we investigated the possible(More)
BACKGROUND Failure of gap junction formation affects the development of various types of cancer. We aimed to clarify the clinicopathologic outcome and prognostic significance of connexin (Cx) 26 in human esophageal squamous cell carcinoma (ESCC). METHODS Immunohistochemical staining for Cx26 was performed on surgical specimens obtained from 123 patients(More)
BACKGROUND Intensive care unit (ICU) psychosis is still a relatively frequent complication after esophageal surgery. We investigated the correlation between ICU psychosis and serum melatonin concentration during the period after esophagectomy. METHODS The study group comprised 41 patients who underwent esophagectomy for treatment of esophageal cancer(More)
BACKGROUND Although patients with recurrent diseases have a very poor prognosis, appropriate pretreatment classification for management of recurrent esophageal cancers has yet to be identified. The patterns of recurrence following radial esophagectomy were retrospectively assessed, and evaluated for possible adaptation as a novel classification of recurrent(More)
OBJECT Whether cerebral vasospasm occurs only in surface vessels or also in parenchymal arterioles is debatable. The present study was undertaken to evaluate comprehensively the microvasculature of the brainstem after experimental subarachnoid hemorrhage (SAH). METHODS Nine mongrel dogs of either sex, each weighing between 18 and 24 kg, underwent double(More)
