Prognostic role of microRNA-210 in various carcinomas: a meta-analysis

Area of Science:

• Oncology
• Molecular Biology
• Biomarkers

Background:

• MicroRNA (miRNA) expression changes are linked to cancer development and progression.
• miRNAs show potential as diagnostic and prognostic indicators in various cancers.
• This meta-analysis focuses on the predictive value of miR-210 for patient survival in carcinomas.

Purpose of the Study:

• To evaluate the global prognostic role of miR-210 expression in cancer patient survival.
• To synthesize evidence from multiple studies on miR-210 and cancer outcomes.
• To identify specific cancer types where miR-210 has significant predictive value.

Main Methods:

• A comprehensive literature search was conducted to identify eligible studies.
• Data from 10 studies on miR-210 expression and survival in various carcinomas were meta-analyzed.
• Hazard ratios (HR) were used to quantify the association between miR-210 levels and patient survival outcomes.

Main Results:

• Higher miR-210 expression in cancerous tissue significantly predicted poorer overall survival (OS) in general carcinomas (pooled HR: 2.41).
• Elevated miR-210 was also a significant predictor for distant-free, relapse-free, or progressive-free survival (pooled HR: 2.84).
• Subgroup analysis revealed that higher miR-210 expression strongly correlated with worse OS in breast cancer (HR: 4.34).

Conclusions:

• miR-210 detection serves as a valuable prognostic marker in cancer patients.
• The findings highlight the significant prognostic utility of miR-210, especially in breast cancer.
• miR-210 warrants further investigation as a potential therapeutic target or biomarker.
