The controversy on whether or not inflammatory infiltrates in chronic lymphocytic thyroiditis predispose to cancer, has now merged into a debate over the role of the inflammatory infiltrates. The question is how and why some cells become transformed and what factors allow them to spread and in some cases become invasive. Here, we show that the amount of inflammatory mediators such as nitric oxide (NO) and high mobility group Box 1 protein (HMGB1) produced in thyroiditis microenvironment increases in tumors and could be involved in the cellular transformation process. NO and HMGB1 are known to attract macrophages that would promote angiogenesis, matrix remodelling and suppression of an efficient immune response. Inflammatory infiltrates could increase the risk of papillary cancer in patients with autoimmune lymphocytic thyroiditis. Cytokines and soluble inflammatory mediators involved in cancer-related inflammation are not only a target for innovative diagnostic and therapeutic strategies but they also represent a future challenge for oncologists. 相似文献

AIM:To define the significance of ischemic heart disease(IHD)(stable angina to infarction) co-existance in Barrett esophagus(BE) patients and patients with esophageal adenocarcinoma(AdE).METHODS: All BE/AdE patients in Blackpool-Wyre-Fylde area and Trikala prefecture identified from medical records. Patient clinical details were obtained from hospital and General Practitioner records. Additional information was gathered from validated questionnaire.RESULTS: Forty(33%) AdE and 83(19%) BE patients had IHD(P = 0.002). Eighteen(15%) AdE and 34(8%) BE patients had suffered a myocardial infarction(P = 0.03). Three(3%) AdE and 7(2%) BE patients had severe heart failure(P = 0.82). Thirty-nine(47%) BE with IHD and 8(20%) AdE patients with IHD consumed aspirin daily(P = 0.004). Seventh-seven(93%) BE patients with IHD and 36(90%) AdE patients with IHD were on statins(P = 0.86). Logistic regression analysis: AdE was more frequent in the elderly,with long termreflux,long BE and concurrent IHD(odds ratio: 2.086,P = 0.001) not consuming statins. Eighteen(22%) BE patients with IHD [16(84%) with myocardial infarction] vs 33(10%) without IHD died from non-neoplastic causes within 24 mo from BE diagnosis(P = 0.005). CONCLUSION: IHD is more prevalent in AdE than BE patients. Increased prevalence of AdE is related with the presence of myocardial infarction but not severe heart failure,possibly because patients with BE and se-vere IHD have low life expectancy. 相似文献
