A national probability‑sample survey of 157 short‑term hospitals in the United States during 1973‑74 collected data on patients admitted with intracranial neoplasms. Annual incidence of primary and secondary intracranial neoplasms was estimated at 17,000 and 17,400 cases (8.2 and 8.3 per 100,000), with rates increasing with age, higher overall in men but women showing higher rates for meningiomas and pituitary adenomas.
A national survey, based on a probability sample of patients admitted to short-term hospitals in the United States during 1973 to 1974 with a discharge diagnosis of an intracranial neoplasm, was conducted in 157 hospitals. The annual incidence was estimated at 17,000 for primary intracranial neoplasms and 17,400 for secondary intracranial neoplasms—8.2 and 8.3 per 100,000 US population, respectively. Rates of primary intracranial neoplasms increased steadily with advancing age. The age-adjusted rates were higher among men than among women (8.5 versus 7.9 per 100,000). However, although men were more susceptible to gliomas and neuronomas, incidence rates for meningiomas and pituitary adenomas were higher among women.
