[Regional differences of mortality from malignancies in Hungary].
BACKGROUND
The mortality of the Hungarian population is very unfavourable in relation to other European countries. Mortality from malignant diseases is the second most frequent cause of death in both sexes. The most frequent localisation of cancer is that of the bronchi and the lungs, followed by colorectal, breast and oral cavity cancers.


OBJECTIVE
Of the publication was to demonstrate the spatial distribution of mortality from malignant diseases of all sites, bronchi and the lungs, as well as mortality from cancer of the thyroid gland and leukaemias, and to evaluate the possible impact of the Chernobyl nuclear accident on the frequency of cancer mortality.


METHODS
The spatial distribution of mortality in the country is evaluated by computing standardized mortality ratio on settlement level, using geographical information system. In case of frequent mortality events a region analysis was carried out, in the opposite case--a cluster analysis.


RESULTS
Regarding the spatial distribution of mortality from all malignant diseases of 0-64 year-old males there are regions with excess mortality in almost each county. In case of women of this age group, there is a significantly higher mortality in Budapest, in three counties in the Eastern part of the country, and in some settlements in Transdanubia. Mortality from the cancer of the bronchi and the lungs significantly accumulates in both sexes in four counties in Eastern Hungary. Mortality from cancer of the thyroid gland and leukaemias does not show typical spatial accumulation as well.


CONCLUSIONS
The premature mortality from all malignant diseases and of cancer of the bronchi and lungs of the Hungarian male and female population shows an increasing tendency. Mortality from the latter cause shows a typical spatial accumulation, which causes should be investigated in analytical epidemiological studies. The potential causative role of the Chernobyl accident could not be proven in any case.
