Iv. Osechinsky et al., INCIDENCE OF LEUKEMIAS AND NON-HODGKIN LY MPHOMAS AMONG CHILDREN LIVING IN DIFFERENT REGIONS OF BRYANSK TERRITORY, Gematologia i transfuziologia, 39(5), 1994, pp. 3-7
Annual incidence of acute leukemia (AL) and non-Hodgkin lymphoma (NHL)
per 100 000 residents aged 0-15 years has been compared for 6 South-W
est regions (supervision territory), 21 control regions (comparison te
rritory) and Bryansk city. Childhood population of the supervision ter
ritory, radionuclide contaminated after the Chernobyl accident, was 58
600 residents, that of comparison territory and Bryansk city 158 600
and 98 900, respectively (1992). In 1986-1991 59 ALL cases (annual inc
idence 3.11 per 100 000), 7 ANLL cases (0.38) 2, 1 and 19 of unspecifi
ed leukemia, CML, NHL (1.00), respectively, have been registered. Inci
dence rate and age distribution for both AL and NHL were typical for c
hildhood population of industrial countries. AL incidence was highest
in Bryansk city (4.21), in supervision territory it was 4.1, in compar
ison regions 3.05. There was a statistically significant excess of AL
incidence in 1986 among those aged 0-15 years in the supervision terri
tory based on 8 cases (annual incidence 13,7, a 95% confidence interva
l 6-27).
