Overexpression of α-sma-positive fibroblasts (CAFs) in Nasopharyngeal Carcinoma Predicts Poor Prognosis
Purpose: The aim of this study is to investigate the differential expression of α-sma-positive fibroblasts (CAFs) in nasopharyngeal carcinomas (NPCs), nasopharyngitis, metastatic tissues of NPCs and its prognostic value in NPCs. Methods: The expression of α-sma-labeled CAFs in 85 NPCs, 32 nasopharyn...

description | Purpose: The aim of this study is to investigate the differential expression of α-sma-positive fibroblasts (CAFs) in nasopharyngeal carcinomas (NPCs), nasopharyngitis, metastatic tissues of NPCs and its prognostic value in NPCs. Methods: The expression of α-sma-labeled CAFs in 85 NPCs, 32 nasopharyngitis and 12 metastatic tissues of NPCs was detected by immunohistochemical method. The relationship between CAFs and clinicopathological parameters of NPCs was analyzed. Results: The high density of CAFs in the NPCs, nasopharyngitis and metastatic tissues of NPCs group were 41.2% (35/85), 6.2% (2/32) and 83.3% (10/12), and a significant difference was showed among these three groups (P<0.05). Chi-square test showed that there was no significant correlation between the density of CAFs and gender, age, N stage, treatment (P>0.05), but closely correlated with T stage and relapse (P<0.05). Kaplan-Meier survival analysis showed that the mean overall survival of high-density and low-density CAFs was 86.8 months and 127.0 months, respectively. Correspondingly, the 5-year survival rates were 57.1% (20/35) and 90.0% (45/50), and there were inversely statistical differences between two groups (P<0.05). Cox multivariate analysis showed that the density of CAFs could be used as an independent prognostic factor for the survival of NPC patients (P<0.05). Conclusions: The density of CAFs could be closely related to the metastasis of NPCs, and also is an efficient prediction factor of poor survival in patients with NPCs. |
