Strategy 1 primarily screened using a cytology screen with HR-HPV testing used for triage. Strategy 2 primarily screened using cytology and HR-HPV co-testing. Strategy 3 primarily screened using HR-HPV testing and triaged HPV-positive women based on cytology. Strategy 4 primarily screened using HR-HPV testing and referred A9 pool HPV-positive women to colposcopy directly, whereas non-A9 HPV-positive women were triaged using cytology.Results: There were 10,183 women included in this study; 16.49% (1677/10,183) were HR-HPV‑positive, 9.52% had abnormal cytology, and 9907 women were normal during follow-up. A total of 276 women were diagnosed with cervical intraepithelial neoplasia 2 or worse (CIN2+), 197 with CIN3 or worse (CIN3+), and 70 with cervical cancer. Moreover, 10.15% (20/197) women who were CIN3+ were identified as cytology-negative, while 8.63% (17/197) were HR-HPV negative (P>0.05). The cumulative risk rate for HPV–/cytology– was 0.836 (95% CI, 0.424–1.648) in CIN3+ cases. Strategy 4 yielded the highest sensitivity for CIN2+ or CIN3+ and the lowest positive predictive value for CIN2+ or CIN3+ among the four screening strategies.Conclusion: The Cervista HR-HPV test can provide a reliable and sensitive clinical reference for the cervical cancer primary screen.
