We compared predictive values of HPV testing based on self- and physician-collected samples, and cytology, in detecting high-grade cervical intraepithelial neoplasia (CIN).<\/jats:p>\n <\/jats:sec>\n \n Methods:<\/jats:title>\n The Cervical And Self-Sample In Screening (CASSIS) study enrolled 1,217 women ages 16\u201370 years prior to scheduled colposcopies. Vaginal specimens were self-collected using the validated HerSwab device. Cervical specimens were collected by gynecologists. Specimens were tested for presence of high-risk HPV (hrHPV) by the Cobas 4800 HPV test. We estimated positive predictive values (PPV) and negative predictive values (NPV) and 95% confidence intervals (CI) for a subset of women (n = 700) who underwent cervical biopsy and cytology at the actual CASSIS visit.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n hrHPV was detected in 329 women (47%) with HerSwab and in 327 (46.7%) with physician sampling. Respective values for HPV16\/18 were 119 (17%) and 121 (17.3%). On histology, 134 women had CIN1, 49 had CIN2, 48 had CIN3, 5 had CIN2\/CIN3, and 3 had cancers. PPVs for CIN2+ of any hrHPV were 28% (95% CI, 23.2\u201333.1) and 29.7% (95% CI, 24.8\u201334.9) for HerSwab and physician samples, respectively. Corresponding values for HPV16\/18 were 43.7% (95% CI, 34.6\u201353.1) and 43.8% (95% CI, 34.8\u201353.1). PPV of cytology (ASC-US+) was 26.6% (95% CI, 21.6\u201332.0). Corresponding NPVs (same order as PPVs) were 96.4% (95% CI, 93.9\u201398.1), 97.8% (95% CI, 95.6\u201399), 90.9% (95% CI, 88.2\u201393.1), 91% (95% CI, 88.4\u201393.2), and 94.7% (95% CI, 91.8\u201396.8).<\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n Our results confirm that HPV self-sampling has comparable performance with a physician-collected sample in detecting cervical lesions.<\/jats:p>\n <\/jats:sec>\n \n Impact:<\/jats:title>\n HPV self-sampling has the potential to increase coverage in cervical cancer screening.<\/jats:p>\n <\/jats:sec>","DOI":"10.1158\/1055-9965.epi-18-1338","type":"journal-article","created":{"date-parts":[[2019,4,23]],"date-time":"2019-04-23T19:46:08Z","timestamp":1556048768000},"page":"1134-1140","update-policy":"https:\/\/doi.org\/10.1158\/crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Predictive Value of HPV Testing in Self-collected and Clinician-Collected Samples Compared with Cytology in Detecting High-grade Cervical Lesions"],"prefix":"10.1158","volume":"28","author":[{"given":"Mariam","family":"El-Zein","sequence":"first","affiliation":[{"name":"1Division of Cancer Epidemiology, McGill University, Montreal, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sheila","family":"Bouten","sequence":"additional","affiliation":[{"name":"1Division of Cancer Epidemiology, McGill University, Montreal, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1172-363X","authenticated-orcid":false,"given":"Karolina","family":"Louvanto","sequence":"additional","affiliation":[{"name":"1Division of Cancer Epidemiology, McGill University, Montreal, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lucy","family":"Gilbert","sequence":"additional","affiliation":[{"name":"2Gynecologic Cancer Service, McGill University Health Centre -
