概括

化疗期间高瘤RNA破坏预测乳腺癌反应. 一个RNA破坏指数 (RDI) ≤3.7的值表明治疗后缺乏病理完整反应 (pCR).

科学领域:

在瘤学瘤学.
分子生物学分子生物学
基因组学就是基因组学.

背景情况:

回顾性研究表明,新辅助化疗期间高瘤RNA破坏与早期乳腺癌的病理完整反应 (pCR) 和改善无病生存率相关.
简单的临床试验 (NCT03524430) 旨在前性验证这些发现.

研究的目的:

验证瘤RNA破坏对早期乳腺癌治疗结果的预测价值.
建立RNA破坏指数 (RDI) 切割点,以预测潜在队列中的pCR.

主要方法:

从BREVITY试验的训练组中分析了80名患者的瘤活检.
在新辅助化疗期间确定最大瘤RNA破坏指数 (RDI) 值.
统计分析用于比较PCR响应者和非响应者之间的RDI值.

主要成果:

获得pCR的患者的最大瘤RDI值明显高于没有pCR的患者 (P=.008).
在治疗期间最大瘤RDI值≤3.7被发现可以预测手术后缺乏PCR,预测值为93.3%.

结论:

在治疗过程中对瘤RNA破坏的评估可以有效地预测早期乳腺癌的术后结果.
这些发现支持基于实时RNA破坏监测的治疗优化潜力.

MicroRNAs

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...
