AHJ：子宫切除术并不增加脑癌风险

与一些晚期分析同都为，一项新的美国分析断定当落魄女同性恋透过输卵管外科手术术（友或不友**外科手术）后，乳癌的后果并未下跌。这些女同性恋儿科的后果这不极低自然环境绝经的女同性恋，该新分析感叹。

波士顿大学首席散文家Karen A. Matthews及朋友在一份简报当中写就了他们的断定，这份简报方案于本周在线公开发表于《美国脑溢血学会杂志》。

Matthews，波士顿的一位杰出的精神病学大学教授和流行病学与社会心理学大学教授，在一份新闻公报当中声明，这些结果对正在考虑输卵管外科手术术的当落魄女同性恋来感叹应当是鼓舞人心的：

“分析最近，比起自然环境绝经后，输卵管外科手术术后的儿科后果位点水平不大可能下跌，”Matthews感叹。

输卵管外科手术术与儿科后果

输卵管外科手术术是一种类似的移除女同性恋输卵管的手术操作方法。有时，病症还移除**，以减少**癌后果。

有时可能明显需要透过该操作方法，比如因为胃癌、输卵管卷曲、表皮都为肌瘤，或因为非常轻的月经过多与痛经，但与此同时，和所有手术一都为，仍要权衡其获利与后果。

因为内分泌改变，在绝经前透过输卵管外科手术术常引发愈来愈年期提前。

一些晚期分析表明输卵管外科手术术提升乳癌的近十年后果，而乳癌是女同性恋头号杀手。而且他们推断，如果同时外科手术**，该后果将愈来愈高。

但是该见解某种程度，主要因为这些分析激进于检验输卵管外科手术术与/或**外科手术术多年之后的儿科后果，而从未将她们在手术之前就可能有的后果考虑进去。

分析者们做了什么

而在该项新分析当中，Matthews及其朋友随访了3,302位美国绝经前女同性恋11年。这些女同性恋参加了全国女同性恋分析（SWAN）。

分析伊始，当这些女同性恋申请加入到SWAN时，她们42-52岁，输卵管原始，有至少1个**，且从未用到甲状腺激素疗法。

在随访期间，每年给她们做检验。在此之后，大多女同性恋达到自然环境绝经岁数，一些透过了输卵管外科手术术友**外科手术术，而一些则不友**外科手术术。

透过输卵管外科手术术的主要主因是表皮都为肌瘤、月经过多和慢性肋骨痛。

分析者在输卵管外科手术术前后检验了与会者的儿科后果，并将这些数据与那些自然环境绝经的女同性恋最后一次月经前后的后果相对来说。

Matthews及其朋友感叹，他们的分析是首项多中华民族分析，了透过输卵管外科手术术与自然环境绝经的女同性恋的儿科后果位点的每年预期改变。

断定了什么

该分析显示输卵管外科手术术前后与自然环境绝经前后心血管后果位点频发变异，在完全相同个体，输卵管外科手术术者与自然环境绝经者变异Mode大不相同；同时，相对来说之下变异Mode显示输卵管外科手术术者心血管后果并未下跌，分析者们感叹。并且，此可能在所有种族组都一都为。

并且，即使在修正可能的制约位点——比如化学物质精确度指数（BMI）——之后，可能仍一都为。输卵管外科手术术友**外科手术术后，BMI确实有所下跌。

主因是什么

Mathews感叹他们这不确定为什么他们的断定与显示输卵管外科手术术升高儿科后果的晚期分析完全相同。

一个主因可能是，他们从未将年轻女同性恋扩展到分析，而愈来愈早透过输卵管外科手术术引发的儿科后果愈来愈高。

另一个主因，Matthews感叹，可能是因为该分析排除了因为胃癌而透过输卵管外科手术术的女同性恋。

SWAN由国家老年医学分析所、国立眼科分析所、国立卫生分析院、女同性恋健康分析室和缺少与替代医学当中心共同完成发起。

2011年，《内科学档案》杂志写道，来自西雅图耶鲁大学的分析者们路透社，他们断定透过了输卵管外科手术术友**外科手术术的女同性恋频发**癌的后果减少，并且频发其它类型胃癌、脑溢血或髋骨折的后果并未升高。

原文读者：Hysterectomy does not increase risk of cardiovascular diseasePositive findings differ from previous studies on hysterectomy, heart disease riskHing a hysterectomy with or without ovary removal in mid-life does not increase a woman's risk of cardiovascular disease compared to women who reach natural menopause, contrary to many previously reported studies, according to research published online today in the Journal of the American College of Cardiology."Middle-aged women who are considering hysterectomy should be encouraged because our results suggest that increased levels of cardiovascular risk factors are not any more likely after hysterectomy relative to after natural menopause," said Karen A. Matthews, PhD, lead author of the study and a distinguished professor of psychiatry and professor of epidemiology and psychology at the University of Pittsburgh.Hysterectomy is the surgical removal of a woman's uterus; it is sometimes accompanied by the removal of the ovaries to decrease the risk of ovarian cancer. Hysterectomy is a common surgical procedure for women, but the benefits must be weighed against potential long-term related health consequences. Cardiovascular disease is the number one killer of women and many studies he shown increased risk of cardiovascular disease to be a health risk associated with hysterectomy, especially accompanied by ovary removal. Researchers in those studies usually evaluated cardiovascular disease risk factors years after hysterectomy and/or ovary removal and did not assess individual risk factor levels pre-surgery.For this study, investigators followed 3,302 premenopausal women between the ages of 42-52 for 11 years who were enrolled in the Study of Women's Health across the Nation (SWAN). Researchers compared cardiovascular disease risk factors in women prior to and following elective hysterectomy with or without ovary removal to the risk factors prior to and following final menstrual period in women who underwent natural menopause.This is the only multiethnic study that has tracked prospective annual changes in cardiovascular disease risk factors relative to hysterectomy or natural menopause.Investigators found that several cardiovascular disease risk factor changes differed prior to and following hysterectomy, compared to changes prior to and following a natural menopause, but those changes did not suggest an increased cardiovascular disease risk following hysterectomy, independent of body mass index, which did increase after hysterectomy with removal of ovaries. These effects were similar in all ethnic groups in the study.Dr. Matthews said it is unclear why this study's findings differed from other studies exploring hysterectomy and cardiovascular risk, but likely factors include the age of participants since hysterectomy that occurs earlier in life may present more cardiovascular risk. Also, earlier studies included women who had hysterectomy for any reason, whereas the SWAN study excluded women who had hysterectomy because of cancers. "This study will prove very reassuring to women who he undergone hysterectomy," said American College of Cardiology CardioSmart Chief Medical Expert JoAnne Foody, MD, FACC. "As with anything, if a woman is concerned about her risk for heart disease she should discuss this with her health care provider."
