Abstract
Aim: To assess the prognostic impacts of PABPC1 on gastric cancer (GC) patients. Methods: The expression levels of PABPC1 in GC tissues and normal gastric tissues were initially compared via bioinformatics analysis. Immunohistochemicalstaining was accomplished to assess the expression of PABPC1 in the included GC patients. Then the impacts of PABPC1 expression on survival of GC patients were evaluated by Cox regression and Kaplan-Meier analyses. Results: The expression levels of PABPC1 in gastric tissues were significantly higher than those in normal gastric tissues (paired, p =0.002; unpaired, p =3.60e-9). By Kaplan-Meier, it was demonstrated that high expression of PABPC1 was significantly associated with worse overall and disease-free survival. Furthermore, high PABPC1 expression was demonstrated to be an independent predictive factor for both overall (p =0.013; hazard ratio =2.058; 95% CI: 1.162-3.644) and disease-free (p =0.018; hazard ratio =2.284; 95% CI: 1.153-4.524) survival. Conclusion: PABPC1 is a potential prognostic biomarker for GC patients.
