Recent researches have shed light on the biological importance of microRNAs (miRNAs) in colorectal cancer (CRC) genesis, progression and response to treatments. The potential utility of miRNAs in the preclinical stage have been explored and investigated. In this review, we explored the literature and reviewed the cutting edge progress in the discovery of noninvasive plasma and faecal miRNAs for CRC early diagnosis, as well as their measurability and predictability. We also discussed the utility of miRNAs as novel prognostic and predictive markers, and their association with CRC clinical phenotypes including recurrence, metastasis and therapeutic outcomes. Finally, we summarised miRNA-related single-nucleotide polymorphisms and their potential influence on sporadic CRC susceptibility and therapeutic response. In conclusion, the use of miRNAs as biomarker for CRC is still in its infancy and need further characterisation and evaluation.
最近的研究揭示了 microRNAs(miRNAs)在结直肠癌(CRC)发生、发展和对治疗反应中的生物学重要性。miRNAs 在临床前阶段的潜在应用已经得到了探索和研究。在这篇综述中,我们查阅了文献,综述了非侵入性血浆和粪便 miRNAs 用于 CRC 早期诊断的最新进展,以及它们的可测量性和可预测性。我们还讨论了 miRNAs 作为新型预后和预测标志物的效用,以及它们与 CRC 临床表型(包括复发、转移和治疗结果)的关联。最后,我们总结了 miRNA 相关的单核苷酸多态性及其对散发性 CRC 易感性和治疗反应的潜在影响。总之,miRNAs 作为 CRC 生物标志物的应用仍处于起步阶段,需要进一步的特征描述和评估。
