The epidemiology of primary brain malignancies

Magy Onkol. 2023 Dec 18;67(4):279-287. Epub 2023 Oct 18.ABSTRACTThe occurrence of central nervous system malignancies is relatively low; however, these tumors exhibit poor prognosis and a high mortality rate. On epidemiological grounds, Hungary was placed in the last third among European countries: in the last decade annually 750 to 1000 new cases were diagnosed and the number of deaths was between 550 and 690, without any apparent trends. Age distribution analyses revealed childhood peak and a higher peak at around 65 years of age. Histologically, heterogeneity was apparent, but at least half of the cases were glioblastomas. The exact etiology of adulthood brain tumors is mostly unknown. Among environmental exposures the effect of ionizing radiation was confirmed, the identification of other potential risk factors requires further examinations. 7-10 percent of brain tumors were hereditary tumor syndromes (Li-Fraumeni, neurofibromatosis, sclerosis tuberosa, von Hippel-Lindau, Gorlin- Goltz). Therefore, genetic testing is recommended for families where the diagnosis of brain tumor is suspected.PMID:38109507
