摘要： 目的探讨血镉水平与乳腺癌临床病理特征间的关系。方法2009年7—12月，收集186例乳腺癌患者外周血标本及临床资料，采用石墨炉原子吸收分光度法测定血镉浓度，利用MannWhitney U检验和KruskalWallis H检验比较不同临床病理特征间的血镉水平，采用Spearman相关分析评价血镉浓度与临床病理特征的相关性。结果受调对象血镉水平［M(QR)］为2.280 （1.579） μg/L，不同年龄和身体质量指数（BMI）指数的患者间血镉水平差异有统计学意义（Z=-2.075，P=0.038; χ2 =7.429，P=0.023）。此外，不同T分期（χ2=10.137，P=0.017）、M分期（Z=-2.225，P=0.026）、临床分期（χ2=16.060，P=0.001）以及人表皮生长因子受体2（HER2）表达状态（Z=-2.072，P=0.038）的乳腺癌患者血镉水平差异也具有统计学意义。除年龄外（r=0.126，P=0.066），BMI、T分期、M分期、临床分期及HER2与血镉负荷均呈正相关（r=0.159, P=0.030；r=0.171，P=0.020；r=0.166，P=0.044；r=0.154，P=0.040；r=0.152，P=0.038）。结论乳腺癌患者血镉水平与其临床病理特征存在一定相关性，高血镉负荷可能预示着不良的疾病进展。

Abstract: Objective To explore the association between blood cadmium levels (BCLs) and clinicopathological characteristics of patients with breast cancer. Methods The clinicopathological characteristics and blood specimens of 186 patients diagnosed with breast cancer were collected between July and December 2009. BCLs were detected by graphitefurnace atomizer absorption spectrophotometer. MannWhitney U test and KruskalWallis H test were used to compare the BCLs of patients with different clinical characteristics. Spearman rank correlation analysis was used to evaluate the relationships between BCLs and some indices of clinical characteristics. Results The BCLs was 2.280(1.579) μg/L. The BCLs were significantly different in patients with different age and body mass index (BMI) (Z=-2.075,P=0.038; χ2=7.429, P=0.023). Also, there were significant differences in different T stages (χ2=10.137, P=0.017), M stages(Z=-2.225, P=0.026), clinical stages (χ2=16.060, P=0.001) and human epidermal growth factor receptor-2 (HER-2) status(Z=-2.072, P=0.038). Excepting for age (r=0.126, P=0.066), BCLs were positively associated with BMI, T stage, M stage,clinical stage and HER2 status (r=0.159, P=0.030; r=0.171, P=0.020; r=0.166, P=0.044; r=0.154, P=0.040; r=0.152, P=0.038).Conclusion The BCLs are associated with some clinicopathological characteristics of breast cancer, and high blood cadmium burden may promote the development of breast cancer.
