Abstract
Brain scans were performed on 116 patients with recurrent breast cancer. Seventy‐eight of 79 (98%) asymptomatic patients with recurrent disease had negative brain scans. Eleven of 37 (30%) patients with central nervous system (CNS) symptoms had scans indicative of intracranial metastases. There was no difference in the distribution of extracranial metastatic disease in patients who had positive brain scans when compared with those who did not. Brain scanning is of value in detecting intracranial metastases in patients with CNS symptoms. Brain scanning seems unnecessary, however, in the staging of patients with recurrent breast cancer who have no CNS symptoms.
