Expression of HIF-1α and BCL-2 in salivary adenoid cystic carcinoma and its clinical significance / 临床与实验病理学杂志

ABSTRACT

Purpose To investigate the relationship of HIF-1α,BCL-2 and clinicopathological features in salivary adenoid cystic carcinoma by detecting the levels of two proteins.Methods Immunohistochemical of SP staining assay was used to detect the level of HIF-1α and BCL-2 expression in fifty-six section from primary resection of salivary adenoid cystic carcinoma.Furthermore,the correlation between the expressions of two proteins with clinical data was evaluated through differently statistical analysis.Results Thirty-six samples (64.3％) were found to express HIF-1α.The level of HIF-1α was significantly correlated with TNM stage of tumors and the primary site of salivary adenoid cystic carcinoma (P ＜ 0.05).Positive BCL-2 expression was detected in fifty-five cases (98.2％).The level of HIF-1 α was positively correlated with that of BCL-2 (P ＜ 0.05)and the significant correlation between HIF-1α and TNM stage was dependent upon the strong expression of BCL-2 (P ＜ 0.05).Conclusion It is therefore indicated that the expression of HIF1α and BCL-2 may influence the clinical stage of salivary adenoid cystic carcinoma.
