title: Central nervous system metastases in breast cancer.
abstract: Sixty-two breast cancer patients with central nervous system (CNS) metastases were reviewed. The CNS was the first site of metastatic involvement in 38 cases (61%). The median survival from the primary diagnosis was 3.0 years; from the diagnosis of the CNS metastasis, 6 months. The interval between primary diagnosis and CNS metastasis had a median value of 2.0 years; between the initial extra-cranial metastasis and CNS metastasis this was 0.9 years. Prognostic factors for the appearance of CNS metastasis could not be identified. Subsequent to CNS metastasis appearing, the well-known prognostic factors for the survival time and the metastasis-free interval lose their importance. Brain metastases occur, above all, in patients aged between 50 and 55 years, very often in the first 2.5 years after the first distant metastasis and not later than 10 years from the primary diagnosis.
