We evaluated compliance with human papillomavirus (HPV) testing and risk-adapted patient pathways and monitored changes in high-grade cervical disease during long-term follow-up. Women aged >30 years attending routine screening for cervical cancer were managed according to results from first-round screening tests (cytology and high-risk HPV; Hybrid Capture 2). Between February 2006 and January 2011, 19,795 of 19,947 women agreed to participate, of whom 4,067 proceeded to a second screening round 5 years after recruitment. Predefined endpoints were compliance, grade 3 cervical intraepithelial neoplasia or cancer (CIN3+), new HPV infection, HPV persistence and abnormal smears in round 2. A total of 765 of 19,795 women (3.9%) in round 1 and 41 of 4,067 (1.0%) in round 2 were referred for colposcopy. Compliance rates with colposcopy were 93.1 and 92.7%, respectively, while histological assessment was performed in 680 of 712 (95.5%) and 36 of 38 (94.7%), respectively. CIN3+ rates were 172 of 19,795 (0.87%; 95% confidence intervals: 0.7-1.0) in round 1 and 2 of 4,064 (0.05%; 95% confidence intervals: 0.006-0.2) in round 2; the difference was statistically significant (Fisher's exact test, p

OBJECTIVE: In February 2006 a pilot project was started in the city of Wolfsburg offering regular routine screening for cervical cancer to members of the Deutsche BKK, a large German health insurance company. The aims of the project are to investigate the feasibility and acceptance of primary HPV screening with defined patient pathways and extended screening intervals. METHODS: The project consists of screening using conventional cytology plus HPV testing with HC2 (for high-risk persons only) for all participants. Women need to be 30 years or older, must be a member of the DBKK and give their written consent. Women with negative results on cytology and HC2 will be retested after 5 years instead of annual intervals as is usually the case in Germany. When both tests are positive, women are called immediately for colposcopy; in women with a negative cytology but positive HC2 test, cytology will be repeated after 6 and HC2 testing after 12 months. In the event of positive findings women will be referred for colposcopy. Women with inconspicuous cytological findings (Pap I/II) and a negative HPV HR test will only be retested again after 5 years but will continue to report for their annual gynaecological preventive medical examinations. RESULTS: From February 2006 to September 2007 12 885 women agreed to participate in the project. 657 (5.1 %) had positive HC2 results and 258 (2 %) had atypical Pap smears at recruitment. 127 (1 %) women were referred for colposcopy, 42 of whom were diagnosed with CIN3 or worse, including 3 invasive cancers and 4 adenocarcinoma in situ. 19/42 women in the CIN3+ group were detected by HPV testing alone; all patients with CIN3+ were HC2 positive. Acceptance of the screening concept is high, less than 1 % of the screening population did not want to participate. No case of severe anxiety related to HPV testing was reported.

After 5 years, the incidence of new HPV infection was 124 of 3,906 (3.2%) and HPV persistence was observed in 22 of 161 (13.7%). Locally organised HPV/cytology co-testing is feasible and acceptable to women. Risk-adapted management rapidly detected a high rate of prevalent CIN3+, while the subsequent long-term risk of new high-grade cervical disease was surprisingly low. It remains unclear if this phenomenon is explained by CIN3 mostly occurring early in life or by modifying the natural course of HPV infection with colposcopy and histological assessment.

Summary Background Currently, the German cervical cancer screening program encompasses an annual cytological Papanicolaou (Pap) smear. However, primary screening for cervical cancer using human papillomavirus (HPV) DNA testing detects cervical pre-cancerous lesions with a significantly higher sensitivity than the Pap smear-based cytology. Objectives In order to develop viable modalities for primary cervical screening incorporating DNA testing for high-risk (HR) types of HPV, we started a pilot project in the city of Wolfsburg, Germany, in February 2006. This program provided a risk-adapted HPV testing-based strategy with defined patient pathways and extended screening intervals for women of 30 years or older. We report here the data of a 3-year follow-up. Study design In the context of the usual routine screening at their office-based gynecologists, women were offered conventional cytology plus the Hybrid Capture 2 (HC2) HPV DNA test. Women with inconspicuous cytological findings (Pap I/II) and negative HC2 test were re-tested after 5 years but continued their annual gynecological examinations. When cytology and HC2 were positive, women were immediately referred to colposcopy. In women with a negative cytology but positive HC2 test, Pap smear was repeated after 6 mo and HC2 testing after 12 mo, and women were called for colposcopy if the HC2 test was persistently positive. Results From February 2006 to December 2008, 16,724 women agreed to participate in the project. Overall, 906 (5.41%) had positive HC2 results and 338 (2.02%) showed atypical Pap smears at recruitment. There were 417 (2.48%) women referred for colposcopy, 104 of whom were diagnosed with cervical intraepithelial neoplasia (CIN) 3 or worse, including 8 invasive cancers and 8 adenocarcinoma in situ (ACIS). No case of CIN 3 or worse occurred in HC2 negative women. Conclusions The presented risk-adapted Wolfsburg Cervical Cancer Prevention Project (“Wolfsburg Model”) has been shown to be effective and feasible in identifying women at risk and for avoiding unnecessary procedures for those who are double negative, thus allowing longer screening intervals and cost savings. Acceptance rates for the program were high for both participating women and gynecologists.
