FDA:乳房假体植入可能会诱发罕见血液肿瘤

2017-03-24 佚名 新浪医药新闻

3月21日,FDA再次发布声明,部分女性接受乳房假体移植(breast implant)可能会诱发一种名叫间变性大细胞淋巴瘤(ALCL)的罕见非霍奇金淋巴瘤。FDA表示,他们目前已经收到了359例乳房假体移植相关的美国女性ALCL病例报告,其中9例死亡。



3月21日,FDA再次发布声明,部分女性接受乳房假体移植(breast implant)可能会诱发一种名叫间变性大细胞淋巴瘤(ALCL)的罕见非霍奇金淋巴瘤。FDA表示,他们目前已经收到了359例乳房假体移植相关的美国女性ALCL病例报告,其中9例死亡。

FDA在声明中指出,我们早在2011年就注意到了一些接受乳房假体移植的女性发生ALCL的病例,但当时并不能确定造成这种疾病风险的增加与乳房假体移植有关。因此我们决定继续收集相关数据。经过6年的观察研究,全球范围内报告的这种病例越来越多,表明乳房假体移植确实与ALCL风险增加有关。

FDA表示,将会采用WHO在2016对乳房假体移植相关ALCL(BIA-ALCL)的定义,以加强大家对这一疾病风险的认知。澳大利亚、法国的监管机构也采取了更多措施,提高大家对乳房假体类型、癌症发生情况及预防措施的知晓度。

FDA指出,相比表面光滑的假体,BIA-ALCL更容易被表面有纹理、手感粗糙的假体诱发。在231例上报假体类型的BIA-ALCL病例中,203例是接受了表面有纹理的假体,28例接受了表面光滑的假体。每家厂商制造的假体的表面纹理差异很大,主要是促进人体组织与假体移植物的融合,以避免内部结痂或其他并发症,但研究人员指出,尚不能把表面有纹理的乳房假体归为BIA-ALCL的罪魁祸首或直接诱因。

据NPR报道,2016年全球进行了大约29万例乳房假体移植手术。近期一项研究结果显示,每100万例接受表面有纹理的乳房假体移植的女性中,会有33例最终罹患ALCL。女性可能会因为医学再建或美容的原因而接受乳房假体移植,但最终发生ALCL的总体风险比未接受移植的女性高65倍。

FDA建议称,已接受假体移植的女性与其为此感到担心,不如坚持执行既定的护理计划,如果有任何担心,可与自己的医生沟通。

AACR 2015:乳房组织密度的人种差异

声明:本文探讨的不是胸与手感,而是会增加骇人听闻臭名昭著的乳腺癌风险的高密度乳房组织。 就目前的研究看来,除了年龄、BMI、激素治疗、生育史、家族史、BRCA1、BRCA2基因缺陷等因素,高密度乳房组织也会显著增加乳腺癌风险。乳房组织密度是指乳房X线照片时观察到的乳腺纤维腺体组织密度,因为乳腺纤维腺体组织在X片上显示为白色,以至于乳腺癌很难直观的检测到。研究显示,高密度乳房组织女性比低密度女

2004年,一位康涅狄格州的妇女被诊断为3期乳腺癌,而她之前并未被告知其乳房X线照片显示乳房组织密度较大。随后,她倡议设立一个新的州法律。人们越来越多地教育女性有关乳房密度和早期癌症检测中补充性筛选的潜在作用。康涅狄格州成为了第一个立法要求医生为乳房密度大的妇女提供补充性的全乳房超声波扫描的州。所谓乳房密度大即超过50%纤维腺组织。截止2015年1月,已经有21个州对乳房密度进行了立法。 告

男人的乳房到底有啥用?

有些动物的雄性动物和雌性动物在生理上差别很大,人类则相似之处远多于不同之处。男性和女性的显著不同之一是女性有乳房,男性为平胸。 胸大是人类的女性审美观之一,这是来自远古的传统。女性的乳房在不哺乳的时候也饱满,这便是进化的后果。在没有婚姻和家庭的漫长的远古岁月中,男子选择女子的主要标准之一是能不能喂养孩子,事关后代繁衍,只能看胸,胸大的女性追求者多,经过这种长期选择,胸大的女性就被
