Background: The expression of serine threonine tyrosine kinase 1 (STYK1), a member of the receptor protein tyrosine kinase (RPTK) family, is abnormal in several cancers. However, the molecular mechanism of STYK1 regulation of gastric cancer (GC) progression is unknown.
Materials and methods: We evaluated STYK1 expression in GC tissues and the corresponding normal tissues. Specimens from 93 patients with GC were examined with immunohistochemical staining. The relationship between STYK1 protein expression and the patients’ clinicopathological features was assessed. Kaplan–Meier and Cox proportional regression analyses were used to evaluate the association between STYK1 expression and survival.
Results: STYK1 expression was decreased in GC tissues. Low STYK1 expression was significantly associated with poor tumor differentiation (P=0.023), advanced clinical stage (P=0.021), and poor overall survival (OS; P=0.034). Univariate and multivariate analyses revealed that STYK1expression was an independent prognostic indicator (HR =0.53, 95% CI =0.29–0.95, P=0.039; HR =0.51, 95% CI =0.24–0.91, P=0.030, respectively).
Conclusion: Downregulated STYK1 expression correlated significantly with poor tumor differentiation, advanced clinical stage, and poor OS in GC. STYK1 might be a diagnostic and prognostic indicator in patients with GC.
