SYNPO2 upregulation is an unfavorable prognostic factor for nasopharyngeal carcinoma patients.

ABSTRACT: Nasopharyngeal carcinoma (NPC) is the most common malignant neoplasm of the nasopharynx. Despite improvements in the clinical treatment strategies for NPC, NPC patients usually have poor survival rates because of late diagnosis, tumor metastasis, and recurrence. Therefore, the identification of potential diagnostic and prognostic markers for NPC is imperative. We investigated the differential expression of cell adhesion-related genes (gene ontology:0003779) and tumorigenesis-related genes (GSE12452) in patients with NPC. The correlations between synaptopodin-2 (SYNPO2) immune expression and clinicopathological features were analyzed using Pearson chi-square test. Multivariate analysis was performed using Cox proportional hazards model. SYNPO2 expression was significantly higher in NPC tumor tissues than in nontumor tissues. High SYNPO2 expression was significantly associated with the advanced disease stage (P = .006). Univariate analysis showed that high expression of SYNPO2 was associated with poor disease-specific survival, distal metastasis-free survival, and local recurrence-free survival in patients with NPC. Notably, our multivariate analysis demonstrated that high SYNPO2 expression was substantially correlated with inferior disease-specific survival (hazard ratio = 1.968, P = .012) and local recurrence-free survival (hazard ratio = 3.386, P = .001). Overall, our findings reveal that SYNPO2 may aid in the development of potential prognostic biomarkers for NPC patients.
