title: [Further epidemiological studies of primary neoplasms of the nervous system in western Poland].
abstract: In West Poland with population on the day of the evaluation of 3,097 thousand the incidence of primary neoplasms of the nervous system was calculated in 5 large administration units (provinces) and in 224 smaller units (communities). The testing of the hypothesis of the equal distribution in the communities demonstrated differences, and in 10 of them this incidence was significantly higher above the mean. The main conclusion of the study is that nervous system neoplasms, 90% of which were located intracranially in our material may occur in foci or clusters of clinical as well as statistical significance.
