Independent Prognosis Prediction of Hepatocellular Carcinoma Using MicroRNA-Based Single and Combined Biomarkers

Area of Science:

• Oncology
• Molecular Biology
• Genetics

Background:

• Hepatocellular carcinoma (HCC) remains a leading cause of cancer mortality worldwide despite available treatments.
• Identifying reliable prognostic biomarkers is crucial for timely intervention and improved patient survival in HCC.
• MicroRNAs (miRNAs) are small noncoding RNAs integral to HCC initiation and progression, with altered expression observed in tumors and circulation.

Purpose of the Study:

• To provide a comprehensive review of current literature on microRNAs as prognostic biomarkers in hepatocellular carcinoma.
• To evaluate the role of both tissue- and circulation-derived miRNAs as independent prognostic indicators in HCC patients.

Main Methods:

• Systematic literature search of studies investigating microRNAs as prognostic biomarkers in HCC.
• Analysis of data on tissue-derived microRNA expression and prognostic significance.
• Analysis of data on circulation-derived microRNA expression and prognostic significance.

Main Results:

• Numerous microRNAs exhibit altered expression patterns in HCC tumor tissues and patient blood samples.
• Both single and combined microRNA signatures show potential as independent prognostic biomarkers.
• Tissue and circulating miRNAs demonstrate promise in predicting patient outcomes and survival rates.

Conclusions:

• MicroRNAs represent a significant class of molecules with potential as prognostic biomarkers in hepatocellular carcinoma.
• Further research validating these miRNA biomarkers could lead to improved clinical management and patient outcomes for HCC.
