Abstract:
Objective:This study aimed to analyze the correlation of the expression of CXCR4, CD44, and CD133 proteins with the clinicopathological characteristics of patients to identify the factors affecting the post-operation survival rate of tongue squamous cell carcinomas (TSCCs). Methods:Clinical data of 44 patients with TSCCs were collected and retrospectively analyzed. The diagno-ses of all cases were pathologically confirmed. CXCR4, CD44, and CD133 expression in 44 TSCCs patients with different pathological grades was examined immunohistochemically. Survival curves were processed in accordance with the Kaplan-Meier method. The Cox regression model was used for the multivariate analysis of relevant clinical and survival data. Results:Among the 44 examined TSCCs patients, 29 cases were well differentiated and 15 were moderately or poor differentiated;11 cases were stageⅠ, 12 were stageⅡ, 8 were stageⅢ, and 13 were stageⅣ. Positive staining of CXCR4, CD44, and CD133 was found in all cases with different degrees. Ac-cording to the pathological tumor grade, the positive rates of CXCR4, CD44, and CD133 expression were 79.54% (35/44 cases),77.27%(34/44 cases), and 75.00%(33/44 cases), respectively. Expression of CXCR4, CD44, and CD133 significantly differed between different histological grades (P<0.05). Correlation analysis indicated that the expression of CXCR4, CD44, and CD133 was positively correlated with the metastasis, recurrence of TSCCs. COX multivariate analysis indicated that CXCR4 expression, clinical stage, and neck metastasis were independent prognostic predictors of TSCCs patients and risk factors of death. Conclusion:CXCR4, CD44, and CD133 may be correlated with the malignancy of TSCCs. CXCR4 expression, clinical stage, cervical lymph node metastasis were the correlated prognosis factors of TSCC patients after operation.
