RETRACTED: Correlation between ER, PR, P53, Ki67 expression, and high-risk HPV infection in patients with different levels of cervical intraepithelial neoplasia (Retracted article. See vol. 21, 2023)

This study was designed to investigate the correlation between high-risk human papillomavirus (HPV) infection and the expression of IHC markers (ER, PR, p53, Ki67) in patients with different grades of cervical intraepithelial neoplasia (CIN). It was a retrospective study, which was conducted from June 2016 to June 2018. 140 specimens of CIN were collected from the pathology department of a certain hospital that included 40 specimens of CIN1, 50 specimens of CIN2 and 50 specimens of CIN3. The expression of ER, PR, P53 and Ki67 were determined by immunohistochemistry. The high-risk HPV infections were detected by PCR fluorescence quantification and were given the correlation analysis. In the 140 specimens, the positive rates of HPV16 and HPV18 in CIN1 specimens were 27.5% and 25.0% respectively, and in CIN2 specimens were 64.0% and 60.0% respectively, and in CIN3 specimens were 90.0% and 92.0% respectively, the difference were statistically significant (p<0.05). There were no significant correlation (p<0.05) between HPV16 and HPV18 positive rate and patient age, tissue differentiation, and tumor size. With the increased of CIN grade, the positive rate of ER, PR, P53 and Ki67 expression in specimen were also increased significantly, and the difference were statistically significant (p<0.05). Pearson correlation analysis showed there were positive correlation (p<0.05) between the positive rates of HPV16 and HPV18 and the positive rates of ER, PR, P53 and Ki67. With the increase of CIN level, the positive rates of high-risk HPV infection as well as ER, PR, P53 and Ki67 are increased, and they have positive correlation.
