AZD9496是一种口服的雌激素受体α小分子抑制剂,也是雌激素受体α的选择性拮抗剂及降解剂。CLIN CANCER RES近期发表了一篇文章,报道了AZD9496治疗ER+/HER2-晚期乳腺癌的安全性、耐受性、药代动力学特征以及初步的抗肿瘤活性。

AZD9496是一种口服的雌激素受体α小分子抑制剂,也是雌激素受体α的选择性拮抗剂及降解剂。CLIN CANCER RES近期发表了一篇文章,报道了AZD9496治疗ER+/HER2-晚期乳腺癌的安全性、耐受性、药代动力学特征以及初步的抗肿瘤活性。

共有45例患者接受AZD9496治疗,分为剂量递增队列和剂量拓展队列。两个队列中,在增加至下一个剂量水平之前均需检测安全性、有效性及药代动力学。根据CTCAE v4.0对不良反应进行分级。利用RECIST v1.1评估客观肿瘤反应情况。研究结果表明,最常见的不良反应为腹泻(35.6%),疲劳(31.1%)和恶心(22.2%),7例患者出现三级及以上不良反应。3例患者出现剂量限制毒性:150mg BID(肝功能异常),400mg BID(腹泻及肝功能检测异常),600mg BID(腹泻),所有的毒性均可逆。未达到最大耐受剂量。1例患者观察到客观缓解,肿瘤标志物Ca15.3也出现下降。4例患者病情稳定持续12个月。

文章最后认为,AZD9496耐受性及安全性良好,在接受过治疗的ER+/HER2-晚期乳腺癌患者中具有延长疾病稳定时间的作用。

JNCI;建议对三阴性乳腺癌进行多基因遗传肿瘤panel检测

采用遗传肿瘤基因panel检测胚系突变可以发现乳腺癌的高风险人群。然而,与三阴性乳腺癌(TNBC)发表风险相关的基因目前尚未明确,除BRCA1突变外,尚未确立其他的易感基因。近日,发布在JNCI的一项研究旨在确定与TNBC高风险相关的基因检测panel。

Int J Cancer:哈佛科学家每天吃大量十字花科蔬菜与患乳腺癌风险降低11% 有关

最近,发表在《国际癌症杂志》上的一项研究评估了特定果蔬与乳腺癌患病风险之间的联系。研究发现,每天多吃蔬果的女性比少吃蔬果的女性患乳腺癌的风险降低了8.5%。其中,多吃十字花科蔬菜及黄色(橙色)蔬菜,与女性患乳腺癌的风险降低11%相关。

乳腺癌早筛应该“因地制宜”!

据2018癌症统计数据显示,我国女性乳腺癌发病率在20岁以后随年龄迅速上升,并于55~60岁左右达到高峰,死亡率随年龄的增长逐渐升高。女性一生中患乳腺癌的概率为10%,北京做的一项研究发现,仅有5.2%新发乳腺癌病例是通过定期乳房X线筛查发现的,而82.1%的女性发现患乳腺癌时已经有明显的症状了。而目前早期乳腺癌患者术后5年生存率已达到90%以上,随着乳腺癌诊疗技术的不断发展进步,实现临床治愈的患
