Abstract:
Objective To explore the significance of DNA quantitative cytology and High-risk HPV-DNA testing in ASCUS riage diagnosis. Methods The DNA quantitative cytology group included 193 cases and the high-risk HPV-DNA comprises 134 cases.ASCUS diagnosed by TBS undergone with automatic cell tumour check analysis system or High-risk HPV-DNA test later, were both done colposcopy directed biopsy soon.There was a comparison between these two cases in pathological results. Results Of the 327 ASCUS cases, 204 cases were histologically diagnosed as inflammation (62.39%), 70 cases were CIN Ⅰ(21.41%), 13 cases were CINⅡ(3.98%), 30 cases were CIN Ⅲ (9.17%),and 10 cases were cervical invasive cancer (3.05%).The histological diagnosis were no statistical distinction between HR-HPV-DNA and DNA Quantitative cytology groups. The negative predictive values of HPV-DNA and DNA Quantitative cytology were 94.74% and 98.93%,respectively. Compared with the percentage of DNA amount greater than 5C (DNA Index>2.5) cells, the histological diagnosis were significantly different between <0.1% and ≥0.1% .DNA heteroploid more than or equal to three were used to predict CINⅡor more severe pathological changes, and its sensitivity, specificity, positive predictive values and negative predictive values were 80.64%,47.06%,40.99%,84.21%, respectively. Conclusion DNA Quantitative cytology and High-risk HPV-DNA test can be used for ASCUS triage, but the cost of DNA Quantitative cytology is cheaper than High-risk HPV-DNA test.
