Abstract: Objective To explore the value of carbonic anhydrase-IX(CA-IX) expressed in cervical exfoliated cells for predicting the natural outcome of cervical intraepithelial neoplasia(CIN)and analysis the relationship between high risk human papillomavirus(HR-HPV) infection and CA-IX. Methods Totally 333 cases who underwent cervical exfoliated cells cytologic examination through thinprep cytologic test(TCT) in Chaoyang hospital from May 2012 to Dec 2013 were enrolled into this study. Immunocytochemistry and HPV DNA tests were applied to study the relationship between HR-HPV infection and CA-IX. Results There was a correlation between CA-IX and HR-HPV infection, the staining of CA-IX in different HPV-infected cell was 60.6% in persistent HR-HPV infection, 38.4% in transient HR-HPV-infected cells and 15.6% in non-HR-HPV-infected cells. Conclusion There was a correlation between CA-IX and HR-HPV infection, the expression of CA-IX in persistent HR-HPV infection was much higher than that in transient HR-HPV-infected and non-HR-HPV-infected cells, showing that CA-IX may be one of the biomarkers of persistent HR-HPV infection leading to CIN.

Key words: cervical intraepithelial neoplasia, carbonic anhydrase-IX, high risk human papilloma virus(HR-HPV), persistent HR-HPV infection
