title: [Comparative analysis of incidence of childhood cancers in four former Provinces of Lublin Region of Poland in 1988-1998].
abstract: The growth of a neoplasm results from interactions of various carcinogenic factors, also environmental ones, so incidence of cancers depends on the place of living. Purpose of the work was the comparative analysis of the number and morbidity of childhood cancers in children living in four former Provinces of Lublin Region of Poland.
  
  
  METHODS
  The study included the population of children and young adolescents, aged 0-17, living in the area of four former Provinces--Biała Podlaska, Chełm, Lublin and Zamość--of the Lublin Region in the years 1988-1998. The analysis determined the number and incidence (Incidence Rate, IR) of all childhood cancers, the parameters were calculated for the whole population according to sex, age on diagnosis and the place of living-urban or rural regions.
  
  
  RESULTS
  Between 1988 and 1998 a total of 856 cases of childhood cancers were noted in Lublin region: 154 cases (IR--141.8 per million) in Biała Podlaska Province, 105 cases (IR--122.0) in Chełm, 403 cases (IR--121.5) in Lublin and 194 cases (IR--115.8) in Zamość. In the 11-year-period of examination the highest incidence was stated in Biała Podlaska Province, but not statistic substantially. Higher incidence revealed among boys (except Zamość Province). Incidence was higher in urban areas than in rural ones in Chełm and Zamość Provinces and the same in urban and rural areas in Biała Podlaska and Lublin Provinces.
  
  
  CONCLUSIONS
  1) The highest incidence of childhood cancers in the Lublin Region was stated in Biała Podlaska Province (it was not statistic substantially), 2) only in Chełm and Zamość Provinces the incidence were higher in urban areas than in rural ones.
