ABSTRACT

Objective:

This study aimed to investigate the expressions of EZH2 and Ki-67 in the salivary adenoid cystic carcino-ma (SACC) of humans and their correlation.

Methods:

A total of 42 cases of SACC tumor tissues and 5 cases of normal tissues were considered to determine the expressions of EZH2 and Ki-67 by immunohistochemistry. The relationship and correlation of such expres-sions with the clinicopathological characteristics were also analyzed.

Results:

The expression of EZH2 was notably higher in SACC than in normal tissues (P<0.05). EZH2 expression was detected in 66.67%(28/42) of the tumor tissues. This expression was correlated with pathological grade and clinical stage. By contrast, EZH2 expression did not correlate with gender, age, and localization. EZH2 was not expressed in normal tissues. The incidence of EZH2 expression in the Ki-67 positive group was 75.76%(25/33) and the incidence in the Ki-67 negative group was 33.33%(3/9). The difference between the two groups was statistically significant (P<0.05). Conclu-sionThe increased expression of EZH2 in SACC was related to tumor proliferation. EZH2 may participate in tumor cell proliferation via cell cycle management.
