Circulating Exosomal miRNAs as Biomarkers in Epithelial Ovarian Cancer

Area of Science:

• Oncology
• Biochemistry
• Molecular Biology

Background:

• Early-stage epithelial ovarian cancer (EOC) detection remains a challenge, contributing to low survival rates.
• EOC subtypes exhibit distinct characteristics, necessitating subtype-specific diagnostic approaches.
• Exosomes, containing microRNAs (miRNAs), are implicated in intercellular communication and cancer progression.

Purpose of the Study:

• To review the potential of circulating exosomal miRNAs as non-invasive biomarkers for early EOC detection.
• To discuss the accuracy and differential expression of exosomal miRNAs in various biofluids.
• To summarize current clinical trials and address reference miRNA selection for EOC detection.

Main Methods:

• Literature review of studies on exosomal miRNAs and EOC.
• Analysis of differential expression of miRNAs in plasma and serum.
• Summary of ongoing clinical trials for miRNA-based EOC detection.

Main Results:

• Exosomal miRNAs show promise as sensitive biomarkers for early EOC detection.
• Differential expression patterns exist between EOC subtypes and biofluid sources.
• Challenges in reference miRNA selection and standardization persist.

Conclusions:

• Circulating exosomal miRNAs represent a high-potential, non-invasive strategy for early EOC detection.
• Subtype-specific exosomal miRNA biomarkers could significantly improve clinical outcomes.
• Further research and standardization are needed for clinical translation.
