Radiology:可提示低核分化等级DCIS的影像学和病理学相关征象

2022-04-15 shaosai MedSci原创

由于DCIS是浸润性乳腺癌的前身,没有发展成浸润性疾病的DCIS病变不会引起症状或死亡,因此人们逐渐开始关注DCIS的过度治疗。

乳腺导管原位癌(DCIS)约占新诊断的乳腺癌的25%,由于乳腺癌筛查的普及,其检出率正在上升。目前DCIS的标准治疗方法包括手术后的辅助治疗,如放疗及内分泌治疗。由于DCIS是浸润性乳腺癌的前身,没有发展成浸润性疾病的DCIS病变不会引起症状或死亡,因此人们逐渐开始关注DCIS的过度治疗。

然而,区分高危DCIS和低危DCIS的预测因素尚未明确,尽管一些临床病理因素(如年轻、病灶较大、激素受体阴性、人表皮生长因子受体2[HER2]阳性、高核分化等级、绒毛膜病变和阳性边缘状态)与DCIS患者的死亡率或复发有关。然而这些因素的相对重要性和相互关系仍不明确,以目前的知识,很难准确预测哪些DCIS患者发展为浸润性乳腺癌的风险更大。

高核分化等级DCIS与高核分化等级浸润性乳腺癌的发生有关,与低核分化等级DCIS相比,高核分化等级浸润性乳腺癌在生物学上更具有侵略性。因此,术前对低核级DCIS进行识别对这些患者来说至关重要。不过,目前还不清楚术前用芯针活检或真空辅助活检(VAB)评估的DCIS的核分化等级是否可以代表整个病变的核分化等级。

近日,发表在Radiology杂志的一项研究评估了与低核分化等级DCIS相关的临床、组织病理学和影像学因素,并开发和验证了一个术前识别低核分化等级DCIS的模型,并进一步明确了与活检时低核分化等级DCIS相关的具体因素。

本项回顾性研究纳入了470名女性患者(中位年龄,50岁;四分位数范围,44-58岁),手术组织病理学评估时有477个为DCIS病变(2010年1月至2015年12月)。患者被分为训练集(n = 330)或验证集(n = 147)以建立一个术前模型来识别低核分化等级DCIS。并对US(肿块、非肿块)和乳腺钼靶(形态学特征、微钙化的分布)的特征进行了评估。计算了低核分化等级DCIS的升级率,并使用多变量回归来评估与后来没有升级的低核分化等级DCIS的相关因素。

将在US表现为肿块但没有微钙化、活检时没有绒毛的病变用来建立一个识别低核分化等级DCIS的术前模型,在验证组中,受试者工作特性曲线下的面积高达0.97(95% CI: 0.94, 1.00)。活检时低核分化等级DCIS的升级率为38.8%(129例中的50例)。Ki-67阳性(几率比,0.04;95% CI:0.0003,0.43;P = .005)与持续的低核分化等级DCIS呈反比。

本研究表明,活检时的低核分化等级原位癌(DCIS)升级为手术时的中高核分化等级的比率为38.8%。然而,DCIS在US表现为肿块、没有微钙化、在活检组织病理学评估时没有绒毛这几点征象,可以用来识别最终组织病理学评估时的低核分化等级DCIS。

Cell:新型单细胞测序技术帮助分析乳腺癌的肿瘤侵袭模式

导管原位癌 (ductal carcinoma in situ,DCIS) 是一种早期乳腺癌,它可能转化成为浸润性导管癌 (invasive ductal carcinoma,IDC)。由于乳腺导管中的癌细胞数目很少和不同肿瘤克隆之间的异质性,研究人员很难对肿瘤细胞的基因组进化过程进行了解。

BMJ研究新闻:早期诊断并早期治疗DCIS是有必要的

据发表于Lancet Oncology的一项新的研究表明,乳腺导管内癌(DCIS)的早期影像发现并接受早期治疗可防止DCIS发展为浸润性乳腺癌。

JAMA Oncol:早期乳腺癌患者有必要接受手术及放射治疗吗?没必要!

据发表于JAMA Oncology的一项新的研究显示,手术和放疗并不适合女性早期乳腺癌的治疗。0期乳腺癌,即导管原位癌(DCIS),是非侵袭性乳腺癌中最常见的形式,占所有的乳腺癌病例的20%。当癌细胞局限于乳导管中而并尚未扩散到周围组织变可确诊DCIS,意味着癌细胞无法转移到乳腺外。诊断为DCIS后,部分女性患者可继续发
