[Statistics of brain metastases].

Frequency and epidemiology of brain metastases are discussed on the basis of autopsy and clinical reports from different countries. Polish bibliography on this subject is also reviewed. Combining data on the frequency of brain metastases from a large autopsy series and the number of cancer deaths from Polish Cancer Registry, the table was built showing the number of probable patients with brain metastases in Poland. The author suggests the necessity of further research on the frequency and results of treatment of brain metastases in Poland.
