The average annual incidence of Wilms' tumor in this population of 2 million children is significantly higher among nonwhites than whites. A significantly larger proportion of black cases has a Wilms' tumor\u2010associated condition including aniridia, genito\u2010urinary anomalies, the Beckwith\u2010Wiedemann Syndrome, and hemihypertrophy. For very young patients, there was a greater tendency for blacks to have bilateral tumors or a tumor\u2010associated anomaly, features characteristic of the hereditary form of Wilms' tumor. The excess risk of Wilms' tumor among blacks may be a result of a higher proportion having a hereditary predisposition or more common exposure to agents capable of inducing germinal mutations.<\/jats:p>","DOI":"10.1002\/mpo.2950120609","type":"journal-article","created":{"date-parts":[[2007,2,20]],"date-time":"2007-02-20T15:54:22Z","timestamp":1171986862000},"page":"401-405","source":"Crossref","is-referenced-by-count":24,"title":["Racial variation in incidence of Wilms' tumor: Relationship to congenital anomalies"],"prefix":"10.1002","volume":"12","author":[{"given":"Shira","family":"Kramer","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna T.","family":"Meadows","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patricia","family":"Jarrett","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2006,7,20]]},"reference":[{"key":"e_1_2_1_2_2","first-page":"49","article-title":"The incidence of childhood cancer: Experience of a decade in a population\u2010based registry","volume":"70","author":"Kramer S","year":"1983","journal-title":"J Natl Cancer Inst"},{"key":"e_1_2_1_3_2","first-page":"313","article-title":"Mutation and cancer: A model for Wilms' tumor of the kidney","volume":"48","author":"Knudson AG","year":"1972","journal-title":"J Natl Cancer Inst"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM196404302701802"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(197706)39:6<2550::AID-CNCR2820390636>3.0.CO;2-Y"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3476(80)80322-2"},{"key":"e_1_2_1_7_2","first-page":"165","article-title":"Persistent renal blastema (nephroblastomatosis) as a frequent precursor of Wilms' tumor; a pathological and clinical review","volume":"2","author":"Machin GA","year":"1980","journal-title":"Am J Pediat Hematol Oncol"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.1159\/000131375"},{"key":"e_1_2_1_9_2","volume-title":"Scientific Tables","year":"1970"},{"key":"e_1_2_1_10_2","volume-title":"Statistical Methods in Medical Research","author":"Armitage P","year":"1974"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM197407042910106"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.5694\/j.1326-5377.1972.tb46675.x"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3476(75)80484-7"},{"key":"e_1_2_1_14_2","unstructured":"National Cancer Institute: \u201cSurveillance Epidemiology and End Results: Incidence and Mortality Data 1973\u20131977.\u201d Bethesda Maryland: NIH Publication No. 81\u20132330 1981."},{"key":"e_1_2_1_15_2","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(197712)40:6<3140::AID-CNCR2820400658>3.0.CO;2-7"},{"key":"e_1_2_1_16_2","first-page":"281","article-title":"Malignant tumors in American black and Nigerian children: A comparative study","volume":"55","author":"Olisa EG","year":"1975","journal-title":"J Natl Cancer Inst"},{"key":"e_1_2_1_17_2","first-page":"496","article-title":"Malignant disease in the Transvaal: VII.
