Neoplasms of the central nervous system in Norway. V. Meningioma and cancer of other sites. An analysis of the occurrence of multiple primary neoplasms in meningioma patients in Norway from 1955 through 1986.

The association between meningioma and a primary malignant neoplasm at another site was studied. The data from the population-based Norwegian Cancer Registry were analysed according to whether the meningioma occurred before or after the malignant neoplasm. Male patients with meningioma showed a raised risk for developing a subsequent renal cancer. A significant association was found between meningioma and subsequent breast cancer in females 50-64 years old at time of meningioma diagnosis and between breast cancer and subsequent occurrence of meningioma. Breast cancer patients with symptoms of an intracranial neoplasm may therefore have a potentially curable meningioma and female meningioma patients over 50 years should be considered for breast cancer screening programmes.
