Method: A cross-sectional study design was adopted, and a total of 609 women who came to seek medical treatment were recruited as the study subjects. Combination testing was evaluated on cervical cancer screening by testing the women for HPV, CT with TCT detection and analyzing the relationship of cervical lesions with HPV and CT infection. Results: The study results showed that 21.57% of the subjects were infected with both HPV and CT, and 48.42% of the cases had abnormal TCT results at the same time. Further data analysis showed that HPV infection was significantly associated with abnormal TCT outcomes (p < 0.05), suggesting a possible synergistic effect of the two infections in cervical lesions. The combined sensitivity and specificity of HPV, CT and TCT detection were 21.57% and 48.42%, respectively, which were significantly higher than that of single detection. Conclusion: In summary, the results of this study support the importance of combined HPV, CT, and TCT testing in cervical cancer screening, and propose the hypothesis that combined testing may improve screening effectiveness. However, further large sample studies are needed to confirm this conclusion and explore the prospects of combined testing in clinical practice.展开更多

The predictive value of CINIII/CIS were studied retrospectively by correlating analysis of different cytology abnormalities and pathology diagnosis.Results: Cytologically, 1,260 out of 31,634 TCT tests showed abnormal squamous cells appearance, including atypical squamous cell of undetermined significance (ASCUS) 675 cases(2.13%), low squamous intraepithelial lesion (L-SIL) 379 cases(1.20%), high squamous intraepithelial lesion (H-SIL)176 cases(0.56%),cancer 30 cases (0.09%). Among 948 patients with pathological diagnosis, there were CINII-III in 70 cases(7.38%) and CINIII/CIS in 56 cases.(5.91%). The relative risks (RR) of different precancerous TCT results in predicting CIN III/CIS validated by pathology are as follow: AUSCUS 14.7% (95% confidence interval (CI) 8.0-27.0), Lsil 13.9% (95% CI 6.3-30.9), Hsil 126.1 (95% CI 60.6-218.6). The RR of AUSCUS group is not significantly different from that of L-SIL group(P =0.951). However, the RR of CINⅢ/CIS morbidity between the H-SIL or cancer group and the ASCUS or L-SIL group are significantly different (all P value <0.01).Conclusion: Vaginoscopic biopsy could verify pathological CINⅡ-Ⅲ and CINⅢ/CIS from cases with abnormal TCT results. There is significantly greater risk of being CINⅢ/CIS validated by vaginoscopic biopsy in the H-SILpatients,while ASCUS and L-SIL group have the coequal risk.展开更多
