UNLABELLED: Purpose of the work was the analysis of the number and structure of leukemia in children living in the Lublin Region of Poland. The study included the population of children aged 0-17 in the years 1988-2000. Among leukemias, according to the International Classification of Childhood Cancers, were counted: lymphoid leukemia, acute non-lymphocytic leukemia, chronic myeloid leukemia, other specified and unspecified leukemias. Number of cases and incidence for the whole group as well as sex, age and descending (rural and urban) distribution of leukemias were calculated.
RESULTS: 244 cases of leukemia were reported (152 boys--62.3% and 92 girls--37.7%). The most of children were from urban regions (139-57%). The mean morbidity rate was 29.9 per million (among boys--36.4/mln, girls--23.1/min). The highest morbidity was observed in years 1989-1990. After 1992 year vehemently decrease of morbidity was noted. Incidence fall with the age, the higher was found in the 0-4 years group (58.7/mln). The decreasing incidence was noted in following years of observation only among the youngest children, while the incidence in children 5-17 years was stable. The higher morbidity was observed among children living in urban regions than in rural ones (35.7/mln vs 24.6/mln) and the incidence in urban region decreased.
CONCLUSIONS: In the Lublin Region lower percentage of leukemia was observed compared to the values determined for the country. Incidence of leukemia was falling, but the analysis in age-groups proved, that it was caused by the decreasing incidence in children under 5 year. The higher morbidity was noted in urban children than in rural ones.
