Abstract:
Objective To explore the clinical value of cervical lesion screening,which was detected by Pap smears,thinprep cytologic test (TCT),full automatic cellular DNA quantitative analysis system,human papilloma virus detection,colposcopy staining biopsy and blind biopsy.Methods 8 780 peoples were as the study object,divided into four groups,positive rate and accuracy of different screening methods;In addition,which were the positive rate of colposcopy staining biopsy and blind biopsy,the positive rate of HPV in all positive biopsy people and negative biopsy people,and the HPV infection rate of various lesions in positive patients were compared,respectivey.Results (1) The positive rates between the four groups showed an increasing trend (P ＜ 0.05).The positive rate of Pap smears and TCT had no statistical difference between every two of them (P ＜ 0.05),the rest were statistically significant (P ＜0.05).(2) The accuracy rates between the four groups showed an increasing trend (P ＜ 0.05).The accuracy rate of Pap smears and TCT had no statistical difference between two of them(P ＞ 0.05),the rest were statistically significant (P ＜ 0.05).(3)The positive rate of colposcopy biopsy under vision inspection with acetic acid (VIA) was higher than that of blind biopsy (P ＞ 0.05).(4) The positive rate of HPV detection of positive biopsy people was higher than that of negative biopsy people(P ＜0.05).(5)In colposcopy biopsy under vision inspection with acetic acid(VIA)group,the HPV positive rates of inflammation showed an increasing trend(P ＜ 0.05) ;in blind biopsy group,the HPV positive rates also showed an increasing trend (P ＜ 0.05).Conclusion (1) HPV test has the highest sensitivity and strongest specificity,cellular DNA quantitative analysis is second,Pap smears is worst,so HPV and DNA detection have more valuable in clinical.(2)There is no significant difference between colposcopy biopsy under vision inspection with acetic acid(VIA)and blind biopsy in clinical,but HPV infection is the key factor,which affects the occurrence,development of cervical intraepithelial neoplasia and gradually progresses to cervical cancer.
