Prognostic value of long non-coding RNA UCA1 in human solid tumors

Area of Science:

• Oncology
• Molecular Biology
• Biomarker Research

Background:

• Urothelial carcinoma-associated gene 1 (UCA1) expression is frequently upregulated in diverse cancer types.
• Elevated UCA1 levels correlate with unfavorable prognoses in cancer patients.

Purpose of the Study:

• To investigate the association between UCA1 expression levels and patient prognosis across various cancers.
• To evaluate UCA1 as a potential predictive biomarker for clinical outcomes and characteristics.

Main Methods:

• A comprehensive literature search was conducted across major scientific databases (PubMed, Embase, Web of Science, CNKI).
• Meta-analysis of 15 studies involving 1240 cancer patients was performed to assess the prognostic value of UCA1.

Main Results:

• High UCA1 expression significantly correlated with shorter overall survival (OS) and disease-free survival (DFS).
• UCA1 upregulation was associated with lymph node metastasis, distant metastasis, and advanced clinical stage.
• Subgroup analyses confirmed these associations across different cancer types, cut-off values, and study designs.

Conclusions:

• Elevated UCA1 expression is a significant indicator of poor clinical outcomes in various cancers.
• UCA1 shows promise as a novel prognostic biomarker and a potential predictor of clinicopathological features.
• Further research is warranted to validate the clinical utility of UCA1 in human solid tumors.
