Testing cervical smears for the presence of high-risk human papillomaviruses (hrHPV) increases the sensitivity for detecting women with underlying high-grade cervical intraepithelial neoplasia (CIN) and provides better and longer protection against invasive cervical cancer compared to cytology testing alone. The Abbott RealTime High Risk HPV test (RealTime) is a hrHPV DNA test with concurrent partial genotyping for HPV16 and HPV18 and aggregate detection of 12 other hrHPV types that have been extensively analytically and clinically evaluated over the last 6 years.


To provide the first 3-year longitudinal data regarding the clinical performance of RealTime, the risk of CIN2+ according to various negative baseline characteristics, and baseline and future risk for CIN2+ at 3 years for women with baseline infection with various hrHPV types were assessed in a cohort of 3,920 Slovenian women that had hrHPV DNA and/or cytology in 36- to 48-month follow-up results after a baseline screening round in 2009/2010.


A total of 36 CIN2+ cases were identified in the second screening round. Of these, 17 CIN2+ cases were identified passively through questionnaires/data registries and 19 cases actively as the result of actions triggered by second-round cytology and/or HPV test results. Accumulation of CIN2+ cases during follow-up occurred predominantly in woman with normal cytology at baseline. Among women >30 years old, significantly better protection against CIN2+ at 3 years was associated with a negative hrHPV DNA result at baseline (risk for CIN2+ 0.04% [95 CI, 0.00-0.22%]) than by normal cytology at baseline (risk for CIN2+ 0.68% [95 CI, 0.40-1.08%]). Women with baseline HPV16 infection had a significantly higher risk of CIN2+ at baseline (21.9% [95 CI, 15.2-30.4%]) and baseline plus future risk at 3 years for CIN2+ (33.3% [95 CI, 24.7-44.0%]) in comparison to women with baseline non-HPV16/18 hrHPV infection (7.0% [95 CI, 4.6-10.2%]) or those that were hrHPV-positive (11.7% [95 CI, 9.1-14.9%]).


3-year longitudinal data reinforce evidence from previous studies that RealTime can be safely used in primary HPV-based cervical cancer screening. Concurrent partial genotyping for HPV16/18 should be strongly considered as a triage method for HPV screen-positive women.
