These data are especially relevant in deciding the age limits for the cytology health service programs. Women aged more than 55 years contribute only 5% of the smears made by house doctors; nevertheless, this group had just as many cases of invasive carcinoma as the younger group. Since 1974 there has been an increase in the diagnosis of adenocarcinoma in situ of the endocervix, probably due to better knowledge of the cytologic and histologic criteria of this lesion. The effects of under-diagnosis of this carcinoma precursor are stressed. It is concluded that it is more important at present to concentrate any additional cytological screening on the \u00ab forgotten group \u00bb of women aged over 55 years and not yet to extend health survey programs to women under 35 years. However, this policy may need to be reviewed if increased rates of preinvasive tumor in the future lead to an earlier average age for invasive tumor.<\/jats:p>","DOI":"10.1177\/030089168206800406","type":"journal-article","created":{"date-parts":[[2018,4,16]],"date-time":"2018-04-16T12:22:14Z","timestamp":1523881334000},"page":"299-305","source":"Crossref","is-referenced-by-count":4,"title":["Investigation of Possible Changes in the Detection of Cervical Carcinoma in Patients of Dutch General Practitioners"],"prefix":"10.1177","volume":"68","author":[{"given":"M.E.","family":"Boon","sequence":"first","affiliation":[{"name":"Department of Pathology, S.S.D.Z., Delft and Leids Cytologisch Laboratorium, Leiden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"W.J.","family":"Rietveld","sequence":"additional","affiliation":[{"name":"University Medical Centre Leiden, Sluiskil, and Leids Cytologisch Laboratorium, Leiden, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.S.","family":"Kirk","sequence":"additional","affiliation":[{"name":"Stichting Streeklaboratorium Zeeland, Sluiskil, and Leids Cytologisch Laboratorium, Leiden, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1982,8,1]]},"reference":[{"key":"bibr1-030089168206800406","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(78)92659-4"},{"key":"bibr2-030089168206800406","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19810801)48:3<768::AID-CNCR2820480318>3.0.CO;2-L"},{"key":"bibr3-030089168206800406","first-page":"539","volume":"25","author":"Boon M.E.","year":"1981","journal-title":"Acta Cytol."},{"key":"bibr4-030089168206800406","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19810715)48:1+<613::AID-CNCR2820481328>3.0.CO;2-Z"},{"key":"bibr5-030089168206800406","doi-asserted-by":"publisher","DOI":"10.1177\/030089168006600205"},{"key":"bibr6-030089168206800406","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(197909)44:3<975::AID-CNCR2820440327>3.0.CO;2-7"},{"key":"bibr7-030089168206800406","doi-asserted-by":"publisher","DOI":"10.1097\/00003081-198003000-00021"},{"key":"bibr8-030089168206800406","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(197804)41:4<1405::AID-CNCR2820410427>3.0.CO;2-S"},{"key":"bibr9-030089168206800406","unstructured":"de JongeH.: Inleiding tot de Medische Statistiek. pp. 209\u2013224, Wolters en Noordhof N.V., Groningen, 1963."},{"key":"bibr10-030089168206800406","volume-title":"Surgical treatment of invasive carcinoma of the uterine cervix.","author":"Ketting B.W.","year":"1981"},{"key":"bibr11-030089168206800406","first-page":"259","volume":"25","author":"Kirk R.S.","year":"1981","journal-title":"Acta Cytol."},{"key":"bibr12-030089168206800406","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-662-07068-0"},{"key":"bibr13-030089168206800406","first-page":"135","volume":"54","author":"Nealon N.A.","year":"1979","journal-title":"Obstet.
