One (POGO) accrues by active registration by pediatric cancer centers, utilizing a histologically based classification system. The other accrues by passive linkage within a larger adult oriented cancer registry (OCR) using a topographically based classification. A reportedly high incidence of childhood cancer based on the latter registry prompted a comparison of the content of the two registries over a 2\u2010year period with the hypothesis that there would be systematic accrual errors. All registrations in both registries for the specified period were reviewed systematically and validated by pathology reports. A small number (2.6%) of registrations in the passive registry were not incident cases, while 2 particular pathologic diagnoses were included in the histologically based registry and not the topographically based registry. These were low grade gliomas and Langerhans cell histiocytosis (LCH). The validated annual incident rate (15.6 per 100,000 children 0\u201314 years of age, excluding LCH) is slightly higher than that reported in other industrialized countries. Ninety\u2010six percent of children aged 0\u201314 were treated in pediatric oncology centers, while only 46% of adolescents aged 15\u201317 were treated in such centers. Of the remaining adolescents, more than one\u2010third had lymphomas. This maldistribution of care provided for the young adolescent population may compromise their survival prospects. The results of this study should prompt revision of health care policy and patterns of service delivery. \u00a9 2003 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/ijc.11004","type":"journal-article","created":{"date-parts":[[2003,3,28]],"date-time":"2003-03-28T12:49:30Z","timestamp":1048855770000},"page":"88-91","source":"Crossref","is-referenced-by-count":100,"title":["Childhood cancer registries in Ontario, Canada: Lessons learned from a comparison of two registries"],"prefix":"10.1002","volume":"105","author":[{"given":"Mark L.","family":"Greenberg","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ronald D.","family":"Barr","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bruna","family":"DiMonte","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eva","family":"McLaughlin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Corin","family":"Greenberg","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2003,2,25]]},"reference":[{"key":"e_1_2_6_2_2","first-page":"126","article-title":"The incidence of pediatric cancer in Ontario\u2014an investigation of unconfirmed cancers","volume":"14","author":"Weir HK","year":"1993","journal-title":"Chronic Dis Canada"},{"key":"e_1_2_6_3_2","volume-title":"This battle which I must fight.
