Seven cases of breast cancer recurrence limited to the central nervous system without other visceral metastases.
We report 7 rare cases of recurrent breast cancers who presented with central nervous system (CNS) metastases as the initial relapse site without any other organ metastases. The average age of the patients at surgery was 42.6 years old of age (median 45:range 32-60), and 6 of the 7 cases (86%) were premenopausal. The mean disease-free period was 25.7 months (median 22, range 2-60 months). The primary tumors were all invasive ductal carcinomas. The estrogen receptor and progesterone receptor status of the 3 tumors available for study were all negative. The metastatic CNS lesions included the cerebrum (4 cases), cerebellum, cervical spinal cord, and meninges. In 6 out of these 7 cases (86%), the CNS metastasis was the initial recurrent lesion. Multidisciplinary treatments including surgery, radiotherapy and systemic or intrathecal chemotherapy were given. Although the mean survival time from clinical manifestations of the metastases of the 4 deceased patients was 20 months (median 20.5; range 6-33), one patient treated with surgery and radiotherapy is been still alive18 years later. These cases were also notable for the fact that the only metastatic site was in the CNS only during the entire clinical course, except for 2 cases, one with ocular adnexa metastasis, and the other with cervical lymph node metastasis. Premenopausal patients with negative hormone receptor status are more likely to develop this type of recurrence, regardless of the histological type. It is necessary to pay attention to neurological symptoms and signs during follow-up of breast cancer patients.
