Objective To investigate the screening value of cervical fluid-based cytology test (TCT), high-risk human papillomavirus (HR-HPV) test, and colposcopy for cervical intraepithelial neoplasia (CIN) and cervical cancer in high-risk populations. Methods A total of 466 patients between January 2013 and January 2015 with a history of intercourse bleeding were enrolled in this study, and the screening value of TCT, HR-HPV test and colposcopy for CIN and cervical cancer were retrospectively evaluated. Results In the 466 patients, 165 were diagnosed with cervical inflammation, 116 with CIN, 182 with grade 2-3 CIN, and 3 with cervical cancer. The colposcopy had the highest sensitivity (84.1%), the lowest specificity (59.4%), high false positive rate (40.6%), low false negative rate (15.9%), and the highest negative predictive value (67.1%). The TCT had the highest specificity (84.8%) and the lowest false positive rate (15.2%). The indicators of HR-HPV were between those of TCT and colposcopy. There were significant differences in terms of these indicators among the three methods (P < 0.05). And the positive prediction value of HR-HPV was the highest (84.5%), while the negative prediction value of colposcopy was the highest (67.1%). There was a significant difference in the predictive value among the three methods (P < 0.05). The consistency of either TCT or HR-HPV alone with pathological diagnosis was poor (K=0.213, 0.343), while that of colposcopy was moderate (K=0.446). Combination of TCT and HR-HPV could significantly improve the diagnosis sensitivity (93.0%) with a lower false negative rate (7.0%); Youden index was 0.736, and the consistency with pathological examination was high (K=0.748). Conclusions For high-risk population with a history of intercourse bleeding or other abnormal cervical disorders, the screening sensitivity of TCT and HR-HPV alone for CIN and cervical cancer is low with a high false negative rate. Colposcopy has a high sensitivity and a low specificity. By combination of TCT and HR-HPV, the validity, reliability and predictive values can be improved significantly, and the sensitivity is high with a low false negative rate and a high consistency with pathological examination.
