Objective:
We assessed the longitudinal risk of developing cervical intraepithelial neoplasia (CINs) with self-sampling human papillomavirus (HPV) tests, based on polymerase chain reaction (PCR) and signal amplification (careHPV), to explore the appropriate intervals for cervical cancer screening.
Methods:
A prospective study was conducted in China during 2017-2020. Participants were invited for PCR and careHPV tests with self-samples at baseline. Women positive in either HPV test underwent colposcopy and biopsy if necessary. Women with baseline CIN grade one (CIN1) or less were followed up over 3 years. The absolute risk was assessed by the immediate risk (IR) and cumulative risk (CR), and the relative risk was assessed by the hazard ratio (HR) with a 95% confidence interval (CI).
Results:
A total of 8,126 women were included in the final analysis. Women positive for the PCR HPV test had comparable IRs of CIN2+ and CIN3+ to those positive on the careHPV test. With triage by HPV genotyping, women with HPV 16/18 infection had the highest IRs of CIN2+ (21.15%) and CIN3+ (9.67%). For CR, women negative for PCR HPV test had a lower risk of CIN2+ than that reported in women negative on careHPV test (0.57% versus 0.98%, HR = 0.58, 95% CI: 0.38, 0.87), but no significant difference was found in the CRs of CIN3+ between them (0.25% versus 0.39%, HR = 0.64, 95% CI: 0.34, 1.20). Among women with CIN1 or less at baseline, women who were persistent or recurrent positive on careHPV or PCR HPV test had a higher risk of developing CIN3+ (11.36%-14.59%), compared with women remained HPV negative from baseline throughout follow-up (≤0.28%).
Conclusions:
Routine screening with 3-year intervals is acceptable for self-sampling HPV tests based on PCR or careHPV test. Women positive on HPV16/18 triaging at baseline or with CIN1 or less at baseline while being persistent or recurrent positive on careHPV or PCR HPV test during 3-year follow-up require immediate colposcopy or treatment.
