A randomized, ongoing trial involved 152,969 invitees and 108,686 attendees in the organized mass screening in Finland in 1999. Drawing invitations from the population registry, women were randomized 2:1 at an individual level to have their smear analyzed either conventionally or with Papnet. The distribution of smears to different cytological categories, detection rates of dysplasias, <jats:italic>in situ<\/jats:italic> carcinomas and cancers were estimated with smears analyzed either conventionally (72,461) or by Papnet (36,225). A total of 108,686 smears were screened and 449 were histologically confirmed as dysplasias and carcinomas. The detection rates for histologically verified carcinoma <jats:italic>in situ<\/jats:italic>\/severe dysplasia, moderate and mild dysplasias were 0.14%, 0.14% and 0.13% with conventional and 0.14%, 0.14% and 0.11% with Papnet, respectively. The detection rate of invasive cancer was 0.06\u2030 (<jats:italic>n<\/jats:italic> = 4) with conventional method and 0.08\u2030 (<jats:italic>n<\/jats:italic> = 3) with Papnet. None of the differences were statistically significant (<jats:italic>p<\/jats:italic> &gt; 0.05). Papnet was able to identify 92.5% of healthy women (normal cytology), and the specificity of conventional smear was 92.9%. The positive predictive value (Pap Classes III\u2013V) of Papnet was slightly but not significantly better (55% <jats:italic>vs.<\/jats:italic> 51%). Papnet screening was feasible as a part of routine screening and performed equally well compared to conventional one methods used in Finland. Organized mass screening was practiced very successfully in the last 38 years. We are going to continue the trial to study the potential trends in cervical cancer incidence in both study arms. \u00a9 2002 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/ijc.10839","type":"journal-article","created":{"date-parts":[[2002,12,9]],"date-time":"2002-12-09T13:47:10Z","timestamp":1039441630000},"page":"422-426","source":"Crossref","is-referenced-by-count":34,"title":["Prospective and randomised public\u2010health trial on neural network\u2010assisted screening for cervical cancer in Finland: Results of the first year"],"prefix":"10.1002","volume":"103","author":[{"given":"Pekka","family":"Nieminen","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matti","family":"Hakama","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Merja","family":"Viikki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jussi","family":"Tarkkanen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahti","family":"Anttila","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2002,11,15]]},"reference":[{"key":"e_1_2_6_2_2","first-page":"279","volume-title":"Trends in cancer incidence.
