【摘要】 乳腺癌是全世界最常见的女性恶性肿瘤,对人类健康和生命构成严重威胁。乳腺癌发病率在全球呈普遍上升趋势,在欧美和拉丁美洲地区维持较高的发病率和死亡率水平。目前在我国的一些城市,乳腺癌死亡率已经高居女性恶性肿瘤之首,而且近年来一直呈上升趋势。乳腺癌的病因复杂,研究认为其发生是遗传和环境因素共同作用的结果。因此,深入进行乳腺癌病因学和分子流行病学研究,寻找和确定相关的分子标志物,筛选高危人群以采取有效的预防控制措施已成为当务之急。本课题采用病例对照研究设计,开展了以医院-社区为基础的乳腺癌分子流行病学研究,重点研究白细胞介素基因多态性与乳腺癌遗传易感性之间的关系。 第一部分 白细胞介素1B基因(Interleukin-1B,IL-1B)多态性与乳腺癌遗传易感性关系的病例对照研究 IL-1B基因的多态性能够影响个体患肿瘤的风险,许多研究发现其对不同人群中消化道肿瘤的发病有比较明确的影响,但国内外对于
【Abstract】 The incidence of breast cancer has been increasing significantly in the last two decades in China, and breast cancer is the leading cause of cancer-related deaths for women in most developed countries. A wide diversity of genetic damage induced by endogenous metabolites and exogenous hazards, such as exposure to ultraviolet, ionizing radiation, and chemical carcinogens, may contribute to the etiology of breast cancer. Inflammation, chronic inflammation in particular, may be one of the important host responses that result in oxidative stress and therefore may contribute to tumor promotion and progression. Many studies have suggested that environmental and genetic factors may play important roles. So, it is urgent to find out BC etiology and take effective prevention measures. To reach this target, a hospital-based molecular epidemiological study on BC was conducted in Jiangsu Province.
