Abstract: Objective: To investigate the expression and clinical significance of SOX-9 in oral squamous cell carcinoma (OSCC). Methods: The expression of SOX-9 protein in normal oral mucosa, atypical hyperplasia of oral epithelium, and oral squamous cell carcinoma was detected by immunohistochemistry, and the correlation between SOX-9 protein and clinicopathological factors was analyzed. Results: The positive expression rates of SOX-9 in normal oral mucosa, atypical epithelial hyperplasia, and oral squamous cell carcinoma were 10% (2/20), 32.1% (9/28), and 79.4% (27/34), respectively. SOX-9 increased in three tissues in turn. The expression of SOX-9 increased in the process of tumor development, and the difference of expression in each group was statistically significant (P<0.001). The expression of SOX-9 was related to tumor volume, lymph node metastasis, and tumor stage. Single factor analysis showed that tumor volume, lymph node metastasis , tumor staging, and SOX-9 positive expression were related to survival time (P<0.05). After Cox multivariate analysis, only lymph node metastasis, tumor stage, and SOX-9 positive expression were independent factors affecting survival time (P<0.05). Conclusions: SOX-9 is highly expressed in oral squamous cell carcinoma. SOX-9 expression is associated with survival rate in patients with oral squamous cell carcinoma.
