ANN ONCOL:三阴性乳腺癌基因特征预测患者结局

对三阴性乳腺癌患者来说,新辅助化疗后残余病灶肿瘤浸润淋巴细胞(TIL)与预后改善有关。ANN ONCOL近期发表了一篇文章,在治疗前标本中寻找基因特征以预测新辅助化疗后TIL浸润程度并检测其对预后的预测价值。

对三阴性乳腺癌患者来说,新辅助化疗后残余病灶肿瘤浸润淋巴细胞(TIL)与预后改善有关。ANN ONCOL近期发表了一篇文章,在治疗前标本中寻找基因特征以预测新辅助化疗后TIL浸润程度并检测其对预后的预测价值。

作者共使用了99例治疗前标本,发现了一个由4个基因组成的特征与高TIL浸润有关。在训练队列(n=99)和独立验证队列(n=115)中评估这一基因特征对远处无复发生存(DRFS)的预后价值。研究建立了由HLF,CXCL13,SULT1E1和GBP1表达水平构成的基因特征来预测新辅助化疗后TIL浸润情况。在训练队列多因素分析中,这一特征与DRFS有关。多独立验证队列多因素分析中,这一基因特征与DRFS显着相关。与治疗前模型临床病理模型相比,这一基因特征可以为预后提供更多的信息。

文章最后认为,该基因特征可以预测新辅助化疗后TIL高水平浸润以及三阴性乳腺癌患者结局,为临床病理模型增加了额外的预后信息。

Lancet oncol:Ipatasertib联合紫杉醇对转移性三阴性乳腺癌的治疗效果。

三阴性乳腺癌是指癌组织免疫组织化学检查结果为雌激素受体(ER)、孕激素受体(PR)和原癌基因Her-2均为阴性的乳腺癌。这类乳腺癌占所有乳腺癌病理类型的10.0%~20.8%,具有特殊的生物学行为和临床病理特征,预后较其他类型差。

J Clin Oncol:外周血cfDNA中的肿瘤分数可以预测转移性三阴性乳腺癌的预后

三阴性乳腺癌只占乳腺癌总体的15%,但却导致了25%以上但乳腺癌相关死亡。过去20年,TNBC患者的总生存没有显着变化。目前,化疗是TNBC主要的治疗手段。对TNBC进行基因组学分析,可能可以发现潜在的生物标志物,指导治疗或预测预后。近日,发表在《JCO》杂志上的研究,采用创新性的方法对转移性三阴性乳腺癌中外周血标本进行检测,发现了重要的预后指标。

Biol Open:靶向DANCR或是治疗三阴性乳腺癌的可行的治疗方法

三阴性乳腺癌(TNBC)对常规的抗激素和Her2靶向治疗无反应,因此有必要确定新的靶向治疗分子。既往研究已经鉴定出参与肝细胞癌发生的长链非编码RNA抗分化ncRNA(lncRNA DANCR),但其在TNBC进展中的表达和潜在作用尚未清楚。本研究中,研究人员使用定量实时PCR(qRT-PCR)对63个TNBC样本及相邻正常组织测定评估,发现TNBC组织中DANCR的表达升高。具有较高DANCR表达

EUR J Cancer:独立于EGFR的Elk1 / CIP2A信号介导了厄洛替尼衍生物TD52对三阴性乳腺癌细胞的凋亡诱导作用

厄洛替尼可试用于两个或两个以上化疗方案失败的局部晚期或转移的非小细胞肺癌的三线治疗。而厄洛替尼衍生物TD52已经被证明可以用于乳腺癌的治疗。

[ABC4]范志民教授:三阴性乳腺癌治疗不再止于化疗

ESO-ESMO第四次进展期乳腺癌国际专家共识会议(ABC4)11月2-4日在葡萄牙的里斯本召开,这次会议的内容极其丰富,从乳腺癌的综合治疗,到医疗过程中的人文关怀;从转化研究到临床挑战,是一场名副其实的学术盛宴。其中占晚期乳腺癌1/3的三阴性乳腺癌(TNBC)是大家关注的话题。这次会议设置了TNBC治疗的专题讨论, Hope S. Rugo等三位国际讲者总结了临床研究的最新进展。

CLIN CANCER RES:Ⅱ/Ⅲ期三阴性乳腺癌患者顺铂,紫杉醇新辅助治疗是否应联合依维莫司

由于肿瘤异质性较强,三阴性乳腺癌靶向治疗一直未取得理想效果。预测治疗反应的分子标志也尚未阐明。CLIN CANCER RES近期发表了一篇文章,研究mTOR抑制剂依维莫司联合顺铂和紫杉醇在三阴性乳腺癌中可以提供协同抗肿瘤作用。
