BACKGROUND Patients with esophageal carcinoma receiving postoperative chemotherapy showed superior disease-free survival than those receiving surgery alone in a Japan Clinical Oncology Group trial (JCOG9204). The purpose of this study was to evaluate optimal perioperative timing-that is, before or after surgery-for providing chemotherapy in patients with(More)
PURPOSE We performed a multicenter randomized controlled trial to determine whether postoperative adjuvant chemotherapy improves outcome in patients with esophageal squamous cell carcinoma undergoing radical surgery. PATIENTS AND METHODS Patients undergoing transthoracic esophagectomy with lymphadenectomy between July 1992 and January 1997 at 17(More)
We previously demonstrated that Porphyromonas gingivalis infection induces neointimal hyperplasia with an increase in monocyte chemoattractant protein (MCP)-1 after arterial injury in wild-type mice. Toll-like receptor (TLR) 2 is a key receptor for the virulence factors of P. gingivalis. The aim of this study was to assess whether TLR2 plays a role in(More)
Although there is a link between periodontitis and cardiovascular disease (CVD), the influence of periodontitis on CVD is unclear. The aim of this study was to assess the relationship between periodontal bacterial burden and CVD. We studied 142 patients with tachyarrhythmia (TA) and 25 patients with abdominal aortic aneurysm (AAA). We examined periodontitis(More)
Marfan syndrome (MFS) is a systemic connective tissue disorder caused by mutations in the extracellular matrix protein fibrillin-1. While it is known that patients with MFS are at high risk of dental disorders and cardiovascular diseases, little information has been provided to date. To clarify the prevalence of periodontitis in patients with MFS, their(More)
Periodontitis is characterized by gingival inflammation and periodontopathic bacteria generate immunological inflammatory responses. Recent epidemiological reports suggest that periodontitis is one of the key risk factors for the onset of cardiovascular diseases. Several studies reported that periodontal bacteria in cardiovascular specimens were frequently(More)
We report a case of primary amelanotic malignant melanoma of the esophagus, an extremely rare disease. A 58-year-old man was diagnosed as having middle esophageal cancer with lymph node metastasis, which was classified as esophageal cancer, Stage III:T3N1M0, by International Union Against Cancer (UICC) criteria. Preoperative chemotherapy was performed, but(More)
BACKGROUND  Periodontopathic bacteria are detected at a high rate in specimens obtained from the aortic walls of patients with abdominal aortic aneurysm (AAA) and are involved in AAA development. The purpose of this study was to clarify the role of Toll-like receptors (TLRs), which are key receptors of virulence factors of many periodontal bacteria, on(More)
BACKGROUND Recent epidemiological studies suggest that periodontitis is a major risk factor for renal failure and cerebral infarction. The aim of this study was to evaluate the association among periodontitis, renal failure, and cerebral infarction, focusing on microbiological and immunological features. METHODS Twenty-one patients treated with(More)
BACKGROUND AND OBJECTIVE Abdominal aortic aneurysm (AAA) is a common and lethal disorder, and MMPs are highly expressed in AAA lesions. Large numbers of periodontopathic bacteria have been reported to be present in specimens obtained from the aortic walls of patients with an AAA. The purpose of this study was to analyze the influence of periodontopathic(More)
