Liquid biopsy offers early cancer detection through minimally invasive tests. This review highlights circulating exosomal long noncoding RNAs (lncRNAs) as promising biomarkers for cancer diagnosis, prognosis, and treatment response, advancing precision oncology.
Area of Science:
- Oncology
- Biomarker Discovery
- Molecular Diagnostics
Background:
- Cancer remains a major global health challenge despite treatment advances.
- Liquid biopsy enables early cancer detection and real-time tumor monitoring.
- Current liquid biopsy focuses on circulating tumor cells (CTCs) and DNA (ctDNA).
Purpose of the Study:
- To review the clinical potential of circulating exosomal long noncoding RNAs (lncRNAs) as liquid biopsy biomarkers.
- To explore their role in cancer diagnosis, prognosis, and treatment response.
- To provide insights into precision medicine for oncology.
Main Methods:
- Literature review focusing on exosomal lncRNAs in cancer.
- Analysis of studies investigating lncRNAs in exosomes for cancer detection.
- Evaluation of lncRNAs' association with tumorigenesis, metastasis, and therapy response.
Main Results:
- Circulating exosomal lncRNAs are closely linked to cancer development and progression.
- These lncRNAs show significant potential as sensitive and specific biomarkers.
- Evidence supports their utility across various stages of cancer management.
Conclusions:
- Circulating exosomal lncRNAs represent a valuable source for liquid biopsy in oncology.
- They offer novel avenues for precise cancer diagnosis and personalized treatment strategies.
- Further research can solidify their role in clinical practice for improved patient outcomes.
