摘要

Background

Growing evidence reported that linc00473 was abnormally expressed in various tumor tissues, elevated linc00473 expression manifested unsatisfactory survival outcome. Due to the inconsistent results from different research, a meta-analysis was executed to examine the link between linc00473 level and cancer prognosis.

Methods

An exhaustive search was made from relative databases, suitable publications were enrolled based on the inclusion and exclusion criteria. The overall literature quality was assessed based on the Newcastle-Ottawa Scale (NOS) score. Relevant data was extracted such as overall survival (OS), TNM stage and lymph node metastasis (LNM) and so on. To determine the stability and dependability of the aggregated results, sensitivity analysis was implemented, while Begg’s analysis was applied to examine possible publication bias.

Results

This meta-analysis encompassed 15 publications totaling 1144 patients. Linc00473 showed elevation in most tumor tissues, with heightened linc00473 expression suggesting inferior cancer prognosis (HR: 1.850, 95% confidence interval (CI): 1.230–2.80, P = 0.003). Subgroup analysis findings revealed comparable negative prognostic implications in the respiratory system (HR: 2.23, 95%CI: 1.39–3.58, P = 0.0008), reproductive system (HR: 3.19, 95%CI: 2.00–5.11, P < 0.00001) and additional systems (HR: 2.56, 95%CI: 1.37–4.80, P = 0.003). Moreover, elevated linc00473 expression correlated with advanced TNM stage (OR: 3.78, 95%CI: 2.75–5.19, P < 0.00001), distant metastasis (OR: 4.61, 95%CI: 2.53–8.39, P < 0.00001), increased tumor size (OR: 3.10, 95%CI: 2.13–4.50, P < 0.00001) and poor histological grade (OR: 1.85, 95%CI: 1.29–2.67, P = 0.0009). Sensitivity analysis confirmed the overall results’ stability and reliability, while Begg’s analysis indicated no substantial publication bias existed among the examined publications.

Conclusion

High linc00473 expression has been detected across diverse tumor tissues, high linc00473 expression implies poor cancer prognosis, linc00473 potentially functions as a prospective therapeutic target and prognostic indicator. More high-quality documents were wished to implement to support the results of this study.
