Abstract: PURPOSE: To investigate the expression and correlation between pyruvate kinase M2 (PKM2) and B7H3 (CD276) in head and neck squamous cell carcinoma (HNSCC) patients. METHODS: Immunohistochemical staining was used to detect the expression of PKM2 and CD276 in 70 HNSCC tissues and 18 normal oral mucosa tissues. The relationship between the expression of PKM2 and CD276 in OSCC tissues and clinical pathological characteristics were analyzed using SPSS13.0 software package. RESULTS: The expression of PKM2 and CD276 in HNSCC was significantly higher than that in normal oral mucosa. The expression of PKM2 and CD276 was strongly associated with TNM stage (P<0.05), while no correlation with gender, age, pathological differentiation grade(P>0.05). The expression of CD276 was positively correlated with the expression of PKM2 in HNSCC. CONCLUSIONS: High expression of PKM2 and CD276 in HNSCC was closely related with malignant progression, and PKM2 may participate in immune regulation by promoting CD276 expression.
