Colorectal cancer (CRC) is one of the most common types of cancer diagnosed worldwide with high morbidity; drug resistance is often responsible for treatment failure in CRC. Non-coding RNAs (ncRNAs) play distinct regulatory roles in tumorigenesis, cancer progression and chemoresistance.
A literature search was conducted in PubMed database in order to sum up and discuss the role of exosomal ncRNAs (ex-ncRNAs) in CRC drug resistance/response and their possible mechanisms.
Thirty-six (36) original research articles were identified; these included exosome or extracellular vesicle (EV)-containing microRNAs (miRNAs), long non-coding RNAs (lncRNAs), circular RNAs (circRNAs) and small-interfering (siRNAs). No studies were found for piwi-interacting RNAs.
Exosomal transfer of ncRNAs has been documented as a new mechanism of CRC drug resistance. Despite being in its infancy, it has emerged as a promising field for research in order to (i) discover novel biomarkers for therapy monitoring and/or (ii) reverse drug desensitization.
结直肠癌（CRC）是全球最常见的癌症类型之一，发病率较高；耐药性常常是 CRC 治疗失败的原因。非编码 RNA（ncRNA）在肿瘤发生、癌症进展和化疗耐药性中发挥着独特的调节作用。
在 PubMed 数据库中进行文献检索，以总结和讨论外泌体 ncRNA（ex-ncRNA）在 CRC 耐药/反应中的作用及其可能的机制。
确定了 36 篇原始研究文章；这些文章包括外泌体或细胞外囊泡（EV）中的 microRNAs（miRNAs）、长非编码 RNA（lncRNA）、环状 RNA（circRNA）和小干扰 RNA（siRNA）。没有关于 piRNA 的研究。
ncRNA 的外泌体转移已被证明是 CRC 耐药性的一种新机制。尽管它还处于起步阶段，但它已经成为一个有前途的研究领域，以（i）发现用于治疗监测的新型生物标志物和/或（ii）逆转药物脱敏。
