Abstract

Abstract: Objective: This study focused on investigating relation between biglycan (BGN) and decorin (DCN) expression and prognostic outcome for oral squamous cell carcinoma (OSCC) cases. Material and Methods: BGN and DCN mRNA and protein expression was detected by qRT‐PCR and Western‐blotting (WB) assays from 31 OSCC samples as well as healthy samples. This work harvested 101 paraffin‐embedded OSCC together with 30 healthy samples, and conducted immunohistochemical (IHC) staining for assessing pathological changes. Association of DCN with BGN within OSCC was explored by Spearman's analysis. Survival rate was explored by Kaplan–Meier (KM) approach. Multivariate analysis was conducted by Cox regression. Results: WB and qRT‐PCR results showed BGN up‐regulation ( p < 0.001, p < 0.0001) whereas DCN down‐regulation ( p < 0.0001, p < 0.0001) with fresh OSCC tissues; the expression of BGN and DCN associated with the OSCC histopathological grade. IHC results suggested elevated BGN level ( p < 0.0001) whereas DCN down‐regulation ( p < 0.0001) with paraffin embedded OSCC tissues. The expression of BGN and DCN associated with histopathologic grades and tumor stage of OSCC. The result of Spearman's analysis demonstrated significant association between the expression of BGN and DCN in OSCC. Survival analysis revealed that patients with higher BGN/lower DCN level showed poor overall survival (OS) as well as tumor‐specific survival (TSS). Multivariate analysis proved that BGN and DCN independently predicted the prognosis of OS and TSS. Conclusion: BGN and DCN expression levels can be adopted for predicting OSCC prognostic outcome.
