Brit J Cancer:妇女生殖因素和外源激素使用与黑色素瘤发病率的关系

2019-03-01 xing.T 网络

该的研究结果表明黑色素瘤风险增加与月经初潮年龄较小和绝经年龄较晚有关。效应修改结果支持这样的假设,即儿童内源性雌激素暴露会增加光致癌性。未来的研究应该纳入个人UVR暴露和阳光敏感性的信息。

虽然雌激素的光敏作用可能会增加紫外线辐射(UVR)对黑色素瘤风险的影响,但很少有前瞻性研究能够全面评估雌激素相关因子与黑色素瘤之间的关系。

近日,肿瘤领域权威杂志British Journal of Cancer上发表了一篇研究文章,研究人员在NIH-AARP饮食和健康研究中评估了167503名非西班牙裔白人绝经后妇女的生殖因素、外源性雌激素使用和第一次原发性侵袭性黑色素瘤之间的关联。基于卫星的环境UVR估计与研究基线参与者的地理编码住宅位置相关联。

黑色素瘤风险增加与月经初潮年龄(≤10岁 vs. ≥15岁:HR=1.25,95%CI为0.92-1.71;趋势P=0.04)和绝经年龄(≥50岁 vs. <45岁:HR=1.34,95%CI为1.13-1.59;趋势P=0.001)相关。在初潮年龄≤10岁的女性中,环境UVR和黑色素瘤风险之间的关系最密切(UVR四分位数增加的HR=1.29; 95%CI为1.05-1.58; 相互作用P=0.02)。黑色素瘤风险与胎次、首次生产年龄、口服避孕药的使用或更年期激素疗法无关。


该的研究结果表明黑色素瘤风险增加与月经初潮年龄较小和绝经年龄较晚有关。效应修改结果支持这样的假设,即儿童内源性雌激素暴露会增加光致癌性。未来的研究应该纳入个人UVR暴露和阳光敏感性的信息。
