Purpose: To study the effect of pituitary tumour transforming gene (PTTG) on invasion and metastasis of salivary adenoid cystic carcinoma.
Methods: The expression of PTTG and bFGF was investigated in 40 salivary adenoid cystic carcinoma tissues and 20 normal salivary tissues by immunohistochemistry. Pearson's Chi-square test and Spearman correlation analysis were used to analyze the data using SPSS 11.5 software package.
Results: The expression of PTTG and bFGF were significantly higher in salivary adenoid cystic carcinoma tissues than in normal salivary gland tissues (P<0.01) and their expression levels were positively correlated (P<0.01).
Conclusions: PTTG and bFGF are highly expressed in salivary adenoid cystic carcinoma. The invasion and metastasis of salivary adenoid cystic carcinoma are correlated with the expression of PTTG. Supported by National Natural Science Foundation of China (81102058).
