Abstract:
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.
Insights
MicroRNAs (miRNAs) show promise as early diagnostic and prognostic biomarkers for colorectal cancer (CRC). Further research is needed to fully characterize these noninvasive markers for clinical application.

Purpose of the Study:
- To review the latest advancements in identifying noninvasive plasma and fecal miRNAs for early CRC diagnosis.
- To discuss the potential of miRNAs as prognostic and predictive markers in CRC.
- To explore the influence of miRNA-related single-nucleotide polymorphisms on CRC susceptibility and treatment.
Main Methods:
- Comprehensive literature review of recent research on miRNAs in colorectal cancer.
- Analysis of studies focusing on noninvasive miRNA detection in plasma and feces.
- Evaluation of miRNA association with CRC clinical phenotypes and therapeutic outcomes.
- Summary of findings on miRNA-related single-nucleotide polymorphisms and sporadic CRC.
Main Results:
- Noninvasive plasma and fecal miRNAs demonstrate potential for early CRC diagnosis, with ongoing evaluation of their measurability and predictability.
- miRNAs are emerging as valuable prognostic and predictive markers, correlating with CRC recurrence, metastasis, and treatment success.
- miRNA-related single-nucleotide polymorphisms may impact sporadic CRC risk and response to therapy.
Conclusions:
- The application of miRNAs as biomarkers for colorectal cancer is still in its early stages.
