Abstract
Background
The mammalian homologs of Lin-28, Lin28 (also called Lin28A) and Lin28B, are promising cancer biomarkers. This meta-analysis was performed to evaluate the prognostic values of Lin28A and Lin28B in multiple human malignancies.
Methods
Systematic searches of the PubMed, Web of Science and Embase were used to identify relevant studies. Pooled hazard ratios (HRs) with 95% confidence intervals (CI) for overall survival (OS), recurrence-free survival (RFS), disease-free survival (DFS), or progression-free survival (PFS) were respectively calculated.
Results
3772 Lin28A-associated patients and 1730 Lin28B-related cases were ultimately enrolled in this meta-analysis. The elevated expression level of Lin28A was significantly associated with poor OS (HR = 1.60, P < 0.001) and poor RFS/DFS/PFS (HR = 1.62, P < 0.001) in patients with malignancies. Lin28B overexpression significantly correlated with unfavorable OS (HR = 1.72, P < 0.001) and RFS/DFS/PFS (HR = 2.35, P < 0.001) of human malignancies.
Conclusions
Lin28A and Lin28B possess significant prognostic values in various human malignancies. Overexpression of Lin28A or Lin28B suggests poor prognosis for cancer patients.
