Expressions of p16INK4a protein in cervical lesion tissues of Mongolian patients and their significances / 吉林大学学报(医学版)

ABSTRACT

Objective:To detect the expressions of p16INK4a protein in the cervical lesion tissues of the Mongolian patients, and to explore the relationship between its expression and the occurrence and development of cervical cancer in the Mongolian patients.Methods:A total of 100 cases of paraffin sections of cervical cancer, cervical intraepithelial neoplasia(CIN),chronic cervicitis and uterine leiomyoma were divided into 25 cases of cervical cancer, 35 cases of CIN, 20 cases of chronic cervicitis, and 20 cases of uterine leiomyoma groups. The expressions of p16INK4a protein in different cervical tissues were detected by immunohistochemical SP method.Results:The positive rates of p16INK4a protern in cervical cancer, CIN, chronic cervicitis and uterine leiomyoma tissnes were 100.0%, 74.3%, 25.0%,and 10.0%, respectively.The results of K-W H rank sum test for multiple sample comparisons showed that the positive expression rate of p16INK4a protein in cervical cancer tissue was significantly higher than those in CIN, chronic cervicitis and uterine leiomyoma tissues(P<0.05).Conclusion:p16INK4a protein can be used as a indicator to screen the Mongolian patients with early cervical cancer.
