Value Health:乳腺癌风险筛查新策略

2017-04-16 MedSci MedSci原创

国家综合癌症网络建议,携带具有乳腺癌风险的基因变异的妇女应考虑降低风险的策略,即增强监测(乳腺磁共振成像和乳房X线照相术)或预防性手术。在具有乳腺癌或卵巢癌综合征家族史的妇女中可以通过多基因批量测试来检测病原体变异体。

近日,来自我国厦门大学的研究人员报道了一项关于乳腺癌风险筛查的研究,相关研究成果刊登于国际杂志Value Health上。

国家综合癌症网络建议,携带具有乳腺癌风险的基因变异的妇女应考虑降低风险的策略,即增强监测(乳腺磁共振成像和乳房X线照相术)或预防性手术。在具有乳腺癌或卵巢癌综合征家族史的妇女中可以通过多基因批量测试来检测病原体变异体。

研究人员从支付者角度对能够符合国家综合癌症Network-defined家族史基因测试标准的两类假设的女性(40岁和50岁同龄人群)队列研究的两种策略有效性和终生成本进行了评估。这两种策略分别为是BRCA1和BRCA2变异体的常规检测策略,BRCA1,BRCA2,TP53,PTEN,CDH1,STK11,PALB2等变体的七基因检测策略。在这些基因中具有阳性致病变异的妇女都接受了遗传咨询,并遵循NCCN乳腺癌风险降低指南。这些指南建议高危妇女通过MRI进行更多的监测,并建议行乳房切除术来降低风险。它还假设多基因panel检测阳性的妇女和BRCA1或BRCA2突变的妇女选择预防性乳房切除术的速率相同。此外,与单独的BRCA1和BRCA2检测相比,使用七基因panel检测,具有较高乳腺癌风险的50岁妇女队列组的ICER为69,920美元/QALY,40岁队列组为48,328美元/QALY。

本项研究表明,测试七个乳腺癌相关基因,然后进行风险降低管理,可以以成本效益的方式提高处于遗传性乳腺癌风险的妇女的预期寿命。

JAMA Oncol:除了朱莉女神告诉你的BRCA,还有哪些基因突变升高乳腺癌风险?

安吉丽娜·朱莉的故事让很多人知道了BRCA基因突变与乳腺癌风险升高有关。美国梅奥诊所的研究人员对现有的成套基因检测项目进行了分析,发现其中有一些确实与乳腺癌有关,而有一些过去认为与乳腺癌有关的,其实可能是被“冤枉”的。他们的结果于4月13日发表在《JAMA肿瘤学》杂志。

Cell Res:乳腺癌调节性T细胞的起源新说

调节性T细胞(Treg)是一类表达FoxP3以及CD25的T细胞亚群,这类细胞对于免疫调节以及耐受反应具有重要的作用,另外,这类细胞在癌症组织中含量较高。Treg细胞能够通过分泌多种可溶性的细胞因子,例如TGF-b,以及表达一些细胞膜抑制性的受体,例如CTLA4等等起到抑制NK细胞以及效应T细胞的抗肿瘤活性的作用。Treg在肿瘤组织

乳腺癌是女性最常见的恶性肿瘤之一,在中国的发病率也呈逐渐走高趋势。据推测,至2021年,中国乳腺癌患者数量将高达250万。乳腺癌最常见的早期临床表现是新发的乳腺肿块,那么除了肿块,乳腺癌还有哪些易被忽略的临床症状?

Sci Rep:致癌性PIK3CA的转化在乳腺上皮细胞中的影响

PIK3CA中的体细胞突变常常见于人类的多种癌症中,包括乳腺癌,它们可以改变细胞的生理学和肿瘤细胞对化学疗法的敏感性。这就使得PIK3CA成为早期检测和个性化治疗的一种有潜力的分子靶标。近期,一项发表在杂志Sci Rep上的研究使用1H核磁共振光谱(NMR)和气相色谱-质谱(GC-MS)与13C稳定同位素标记的葡萄糖和谷氨酰胺作为代谢示踪剂,探测了MCF10A细胞系中PIK3CA(H1047R)突
