During the 1980s, the incidence of primary malignant brain and other central nervous system tumors (hereafter called brain cancer) was reported to be increasing among all age groups in the United States, while mortality was declining for persons younger than 65 years.
We analyzed these data to provide updates on incidence and mortality trends for brain cancer in the United States and to examine these patterns in search of their causes.
Data on incidence, overall and according to histology and anatomic site, and on relative survival were obtained from the Surveillance, Epidemiology, and End Results (SEER) Program of the National Cancer Institute for 1975 through 1995.
Mortality data were obtained from the National Center for Health Statistics.
Medicate procedure claims from the National Cancer Institute's SEER-Medicate database were used for imaging trends.
Statistically significant changes in incidence trends were identified, and annual percent changes were computed for log linear models.
Rates stabilized for all age groups during the most recent period for which SEER data were available, except for the group containing individuals 85 years of age or older.
Mortality trends continued to decline for the younger age groups, and the steep increases in mortality seen in the past for the elderly slowed substantially.
Patterns differed by age group according to the site and grade of tumors between younger and older patients. (...)
