JNCI:检测指甲中硒浓度,预测前列腺癌风险

2016-09-21 Seven L 译 MedSci原创

一些观察研究表明,更高的硒水平与更低的前列腺癌风险有关;但是这些研究都没有为硒水平与前列腺癌风险之间的关系提供精确评估,比如不同前列腺癌分级分期与硒水平的关系如何? 研究纳入了来自15个前瞻性研究的参与者,对他们的数据进行了合并分析,这些参与者主要是欧洲血统的白人男性。评估了血液或指甲中硒浓度与前列腺癌风险之间的关联。使用多变量调整后的logistic回归分析,评估两者间关联。 数据显

一些观察研究表明,更高的硒水平与更低的前列腺癌风险有关;但是这些研究都没有为硒水平与前列腺癌风险之间的关系提供精确评估,比如不同前列腺癌分级分期与硒水平的关系如何?

研究纳入了来自15个前瞻性研究的参与者,对他们的数据进行了合并分析,这些参与者主要是欧洲血统的白人男性。评估了血液或指甲中硒浓度与前列腺癌风险之间的关联。使用多变量调整后的logistic回归分析,评估两者间关联。

数据显示,血液中硒浓度与总的前列腺癌风险无关(硒浓度每增加80%,多因素校正后前列腺癌OR=1.01, 95% CI = 0.83 to 1.23;基于4527例前列腺癌患者和6021例对照组参与者)。不过前列腺癌侵袭性间具有异质性(如晚期或致死亡的前列腺癌,异质性分析P = .01);血液中硒浓度高,与侵袭性疾病风险的降低有关(OR = 0.43, 95% CI = 0.21 to 0.87),但是与非侵袭性疾病无关。

指甲硒浓度与总的前列腺癌风险呈负相关(OR = 0.29, 95% CI = 0.22 to 0.40, P-trend < .001;基于1970例前列腺癌患者和2086例对照组参与者);不管是非侵袭性疾病(OR = 0.33, 95% CI = 0.22 to 0.50)还是侵袭性疾病(OR = 0.18, 95% CI = 0.11 to 0.31, 异质性分析P = .08),指甲硒浓度与前列腺癌风险呈负相关。

指甲硒浓度与前列腺癌风险呈负相关,但是血液中硒浓度与前列腺癌风险无关;不过对于侵袭性前列腺癌,指甲和血液硒浓度均可以反应其风险。

AJCN:机体中硒的水平或影响个体患癌的风险

作为微量营养元素,硒构成了我们饮食中的必要部分,近日,来自国际癌症研究机构(IARC)等处的研究人员通过研究发现,血液中较高的硒水平或许和个体患肝癌风险降低直接相关,除了其它风险因素以外,研究者还检测了血液中的硒水平影响机体患其它癌症风险的机制,相关研究刊登于国际杂志the American Journal of Clinical Nutrition上。 许多食物中都含有硒(Se),比如鱼类

JNCI:补充硒不能预防结直肠腺瘤,还会增加2型糖尿病风险

既往的研究表明,补充硒可能有助于预防结直肠癌;结直肠腺瘤作为结直肠癌的前体,那么补充硒能否预防结直肠腺瘤?此外,硒补充剂还可能会增加2型糖尿病风险。 Sel/Cel试验是一项随机安慰剂对照试验,每天服用硒200 µg(富硒酵母)和/或塞来昔布400 mg,作为结直肠腺瘤的预防措施。研究纳入40-80岁结肠镜下切除腺瘤的男性和女性。主要结果为腺瘤的发展。虽然在其他试验中,塞来昔布表现出了心血管
