Objective: To report detailed age‐specific outcomes from the first round of an English pilot studying the implementation of high‐risk human papillomavirus (HR‐HPV) testing in primary cervical screening. Design: Observational study with screening in 2013–2016, followed by two early recalls and/or colposcopy until the end of 2019. Setting: Six NHS laboratory sites. Population: A total of 1 341 584 women undergoing screening with HR‐HPV testing or liquid‐based cytology (LBC). Methods: Early recall tests and colposcopies were recommended, depending on the nature of the screening‐detected abnormality. Main outcome measures: We reported standard screening process indicators, e.g. proportions with an abnormality, including high‐grade cervical intraepithelial neoplasia (CIN2+) or cancer, and the positive predictive value (PPV) of colposcopy for CIN2+, by screening test and age group. Results: Among unvaccinated women screened with HR‐HPV testing at age 24–29 years, 26.9% had a positive test and 10.4% were directly referred to colposcopy following cytology triage, with a PPV for CIN2+ of 47%. At 50–64 years of age, these proportions were much lower: 5.3%, 1.2% and 27%, respectively. The proportions of women testing positive for HR‐HPV without cytological abnormalities, whose early recall HR‐HPV tests returned negative results, were similar across the age spans: 54% at 24–29 years and 55% at 50–64 years. Two‐thirds of infections at any age were linked to non‐16/18 genotypes. Among women with CIN2, CIN3 or cervical cancer, however, the proportion of non‐16/18 infections increased with age. As expected, the detection of abnormalities was lower following screening with LBC. Conclusions: These data provide a reliable reference for future epidemiological studies, including those concerning the effectiveness of HPV vaccination. Data from the English pilot study provide a comprehensive overview of abnormalities detected through HPV screening. Data from the English pilot study provide a comprehensive overview of abnormalities detected through HPV screening. [ABSTRACT FROM AUTHOR]

The article presents arguments in favor of human papillomavirus (HPV) primary cervical screening. Topics discussed include some large randomised trials which showed that HPV testing is more sensitive than cytology for detecting underlying high-grade cervical intraepithelial neoplasia (CIN), and the fact that some cases of CIN stage 3 are caused by non-vaccine types.
