医护人员将乳腺癌显像举到光板前

一些绝经期较早的人患乳腺癌的风险可能会增加, according to research led by scientists at Huntsman Cancer Institute at the University of Utah (the U) and the Spencer Fox Eccles School of Medicine at the U.

研究人员发现,在46岁之前经历更年期的女性患乳腺癌的可能性几乎是男性的两倍 breast cancer as other women of similar ages. Their relatives were also more likely to have breast, prostate, or colon cancer. The study is published in The Journal of Clinical Endocrinology and Metabolism.

Primary ovarian insufficiency (POI), 卵巢因过早失去卵子而停止正常工作的一种情况, 导致一些人在相对年轻的时候就进入更年期.

“[Women with POI] are at risk for a number of diseases...大发娱乐的研究结果表明,这些女性中的一些人也应该在她们的一生中监测癌症风险.”

“当女性经历原发性卵巢功能不全时,她们有患骨质疏松症和心血管疾病等多种疾病的风险,” says the study’s senior author Corrine Welt, MD她是美国国立卫生研究院内科内科的内分泌学家和研究员. “大发娱乐的研究结果表明,这些女性中的一些人也应该在她们的一生中监测癌症风险.”

“这项工作增加了对原发性卵巢功能不全和生殖癌症之间关系的理解, which could guide preventive strategies,” says study co-author Nicola Camp, PhD洪博培癌症研究所(Huntsman cancer Institute)的癌症遗传流行病学家,也是美国癌症研究中心的主任 Utah Population Database (UPDB). 研究小组利用独特的资源揭示了健康状况之间的关系.

Connecting cancer and reproductive health

Primary ovarian insufficiency often runs in families, with inherited, genetic factors accounting for up to 43% of cases. 先前的研究发现,一些被认为导致生殖健康状况的突变与那些与癌症有关的突变相似.

这种相关性促使研究小组调查这些人患癌症的风险是否高于一般人群. They also analyzed women with a related condition, early menopause, which occurs between ages 40 to 45. 参与研究的女性患乳腺癌的几率几乎是普通人群的两倍.

此外,POI患者的亲属患癌症的风险更高:

2nd-degree relatives: Aunts, uncles, grandparents, nieces, and nephews

30% increased risk for breast cancer
50% increased risk for colon cancer

1st, 2nd, and 3rd degree relatives: Great-grandparents and first cousins

30-60% increased risk for prostate cancer

威尔解释说,这些发现可能会对表亲的健康产生广泛的影响. POI和提前绝经的人可能会从增加癌症筛查中受益. Additionally, 来自这些癌症易感家庭的育龄个体可能是不孕症检测的候选人.

In addition to the UPDB, 科学家们还检查了两个医疗系统的医疗记录——犹他大学医疗系统和山间医疗系统,这两个系统为犹他州85%的人口大发娱乐提供服务. 1995年至2021年间,613人被诊断为POI,另有165人被诊断为提前绝经. Then, those individuals were cross-referenced with the Utah Cancer Registry该机构追踪了该州的癌症发病率和死亡率.

“[UPDB]是一个就不同疾病之间的关系提出问题的完美平台,其目标是指导预防战略和改善人口健康.”
Nicola Camp, PhD

Results on familial cancer risk came from more than 26,在癌症登记处和UPDB中有代表的500名亲属. “犹他州人口数据库是一个多源数据资源,拥有超过10亿条与健康相关的记录, 50 years of cancer data, 至少是四代人的家庭结构.5 million people,” Camp says. “这是一个完美的平台,可以就不同疾病之间的关系提出问题,以指导预防战略和改善人口健康.”

Searching for missing links

提早绝经和癌症之间的联系存在于大发娱乐身体的细胞深处, the study suggests. 为了揭示这些联系,科学家们检查了六名女性的DNA. 每个人都有一种不同寻常的基因变异,这种基因可以保持大发娱乐的细胞健康. According to Welt, 这些基本过程中的缺陷既会损害卵巢的健康,也会增加细胞分裂失控的可能性, a hallmark of cancer.

了解这些健康状况的根本原因可能有一天会导致新的治疗方法. For now, however, they offer answers. “对于被诊断为POI的女性来说,这是毁灭性的,”韦尔说. “Having an explanation helps them find closure.”

这项研究得到了尤尼斯·肯尼迪·施莱弗国家儿童健康与人类发展研究所的支持,包括R56HD090159和R01HD099487, 国家卫生研究院/国家癌症研究所,包括P30 CA02014, and Huntsman Cancer Foundation.
