Abstract

Objectives: Accumulating evidence indicates that the expression and/or variants of several genes play an essential role in the progress of colorectal cancer (CRC). The current study is a meta-analysis undertaken to estimate the prognosis and survival associated with , , , , , and genes among CRC patients.

Methods: The authors searched PubMed, EMBASE, and Science Direct for relevant reports published between 2000 and 2020 and analyzed them to determine any relationship between the (immunohistochemically/sequencing-detected) gene expression and variants of the selected genes and the survival of CRC patients.

Results: The analysis included 34,074 patients from 64 studies. To evaluate association, hazard ratios (HRs) were estimated for overall survival (OS) or disease-free survival (DFS), with a 95% confidence interval (CIs). Pooled results showed that overexpression, mutation, or 4 loss of expression, mutations, and expression were associated with shorter OS. overexpression (HR: 0.137 (95% CI: 0.131-0.406)), loss of expression of or 4 (HR: 0.449 (95% CI: 0.146-0.753)), the mutations of (HR: 0.179 (95% CI: 0.126-0.485)), and expression (HR: 0.485 (95% CI: 0.772-0.198)) also presented risk for shorter DFS.

Conclusions: The present meta-analysis indicates that overexpression or underexpression and variants of , , 4, , and genes potentially acted as unfavorable biomarkers for the prognosis of CRC. The gene was not associated with prognosis.
