Sci Rep:爸爸超重会引起女儿乳腺组织发生改变,增加患癌风险

肥胖的雄性小鼠和正常体重的雌性小鼠交配生产的雌性幼崽在出生时、幼龄期体重超重,乳腺组织发育滞后,而且它们的乳腺癌发病率会增加。

首个有关父亲肥胖对未来几代人患癌风险影响的动物研究文章于6月24日发表在《Scientific Reports 》杂志上。

研究人员称他们已经发现肥胖可改变小RNA(microRNA)信号、基因表达的表观遗传调节剂、父亲的精子和女儿的乳房组织的证据,这表明小RNA可能从肥胖父亲中携带了表观遗传信息到他们的女儿身上。

miRNA可以调节胰岛素受体信号,它与体重变化相关。其它分子途径与癌症发展,如缺氧信号通路相关。

母亲怀孕时超重会生产巨大儿,这些孩子可能在以后的生命中会增加乳腺癌的风险。目前大部分的研究都偏重母亲这方面,几乎没有有关父亲超重对他的后代患癌症风险的影响的相关研究。

“这项研究提供证据表明,在动物中父亲的体重影响了他们女儿的出生时体重和童年期体重以及她们以后生活中患乳腺癌的风险。”Sonia de Assis博士说。

“我们的研究是在小鼠身上做的,但它概述了一些人类发生的类似情况,与瘦的男性相比,肥胖男性精子中有明显的表观遗传性改变。动物研究表明,精子中表观遗传的改变可能影响下一代患癌症的风险。”

Sonia de Assis说,“女性和男性应该均衡饮食,保持健康的体重和生活方式,这不仅为了自己的健康,也是为了后代的健康着想。”

J Breast Cancer:发现腋窝包块,危险不容忽视!

  J Breast Cancer:发现腋窝包块,危险不容忽视! 乳嵴的不完全退化是造成异位乳腺组织的原因,异位乳腺组织没有分泌导管系统,但组织学与正常乳腺组织相同,然而发生在异位乳腺组织的微钙化却很难被钼靶检查发现,本病例报道一例通过钼靶检查发现腋窝异位乳腺组织的导管原位癌。 一52岁有副乳的女性行钼靶体检发现右腋窝异位乳腺组织有群集钙化点,建议随访,3个月后复查发现右腋窝

HER2阳性乳腺小肿瘤须靶向治疗吗

乳腺癌是一种具有高度异质性的肿瘤,现今,在分子分型指导下的综合治疗是乳腺癌治疗发展的趋势。在浸润性乳腺癌中,约有20%患者的人表皮生长因子受体2(HER2)为阳性;众多研究指出,HER2阳性是乳腺癌早期复发转移的独立危险因素。曲妥珠单抗是首个应用于临床的抗HER2靶向治疗药物,该药物是人源化的HER2单克隆抗体,大量数据表明辅助治疗阶段应用曲妥珠单抗联合化疗可使乳腺癌复发、转移风险相对降低约5

EBCC 10:糖尿病的治疗是如何影响乳腺密度的?

第十届欧洲乳腺癌会议(EBCC-10)称:糖尿病治疗中,无论是饮食还是药物(如二甲双胍),均可以降低乳腺密度(MD),但是胰岛素的使用会增加MD。 乳腺密度是乳腺癌的危险因素之一,高密度乳房(≥75%)女性与MD≤25的女性相比,乳腺癌风险高4-6倍。

Ca Cau&Con :青年期-中年期饮酒与乳腺影像学密度的关系

79%的成年女性报告有饮酒史。研究结果发现与青年期不饮酒的成年女性参与者相比较,调整混杂因素后,参与者饮酒量大于7份/每周与乳腺百分比密度负相关(β=−5.1, 95%CI −8.7-−1.5; P=<0.01)。参与者青年期最大饮酒量与乳腺致密区呈负相关,但相关关系没有统计学显著性(P=0.15)。与研究时不饮酒的参与者相比,参与者目前饮酒量>7份/周与乳腺密度百分比呈负相关(β=−3.1, 9

大型前瞻性乳腺肿瘤多中心研究中国站(BE3研究)中期总结即将发布

超声E-成像,全称为二维实时剪切波弹性成像,是法国声科影像创造的全球唯一全面通过FDA认证的实时、全幅、全定量的软组织硬度测量工具,在它出现的短短数年间,其可以在浅表组织、腹部组织、腔内组织广泛便捷应用的特性,得到了国内外顶级超声及医学专家的一致认可。日前,有关E-成像的超大型前瞻性乳腺肿瘤多中心研究中国站(BE3研究)的中期报告即将发布。 2014年6月,BE3研究在西安正式启动,两位PI正是

Breast Cancer Res:乳腺实质背景强化BPE变化值可预测女性乳腺癌

目的:我们针对乳腺动态对比增强磁共振成像(DCE-MRI)提出一个完全自动化的方法推导乳腺实质背景强化(BPE)的定量方案,对这些方案进行初步评估,评价乳腺癌易感性基因1/2(BRCA1/2)突变携带者组风险降低的输卵管卵巢切除术(RRSO)的影响。方法:在医疗保险可携性及责任法案(HIPAA)和机构审查委员会批准下,乳腺动态对比增强磁共振成像DCE-MRI数据来自于对50名 BRCA1/2携带者
