摘要:
Background: CareHPV is a highly promising screening HPV assay that functions as a simplified and rapid point-of-care test, making it particularly well-suited for low-resource areas. It exhibits high sensitivity for detecting cervical precancerous lesions in cross-sectional study design. However, there is still limited evidence on the long-term protection of careHPV testing in the practical setting. Methods: A government-led cervical cancer screening program was implemented in Ordos City, China, specifically targeting female residents aged 35-64 years since 2016. CareHPV specimens were collected and visual inspection with acetic acid and Lugol iodine (VIA/VILI) was performed in the baseline screening. Women who were HPV-positive or VIA/VILI-suspected cancer at baseline were invited for a one-year follow-up screening. At the same time, those who were HPV-negative were scheduled for a 5-year rescreening. Women diagnosed with cervical intra-epithelial neoplasia grade 2 or worse (CIN2+) would be referred to clinical treatment as per the clinical guidelines. The current study includes participants who had valid baseline screening results and attended follow-ups with valid careHPV results conducted between January 2017 and December 2021, aiming to assess the long-term risk stratification for careHPV. Cumulative incidence rate (CIRs) and hazard ratio (HRs) for CIN2+ were calculated, using survival analysis. Results: Among the 179,306 women enrolled in the baseline screening between 2016 and 2020, 12.60 % tested positive for careHPV, with 657 cases of CIN2+ identified. The final analysis included 18,562 women in our study, of whom 58.54 % were careHPV-positive at baseline. The final analysis consisted of 17,905 women who underwent screening between 2016 and 2020 and attended follow-ups from 2017 to 2021, with valid HPV results, and 657 women who identified as CIN2+ at the baseline. The 5-year CIRs were 0.003 and 0.101 among women who tested negative and positive for baseline careHPV, respectively. The 5-year CIRs for developing CIN2+ during follow-ups were 0.009, 0.009, and 0.11 for the groups of women who transitioned from careHPV-negative to positive (831, 4.64 %), careHPV-positive to negative (6688, 37.35 %), and maintained a stable positive careHPV status (3535, 19.74 %), respectively. Conclusions: Our findings support the long-term safety and protection of careHPV testing in 5-year follow-ups of screening programs. CareHPV represents a viable option for regions with limited healthcare resources. (c) 2024 The Author(s).
