Abstract
BACKGROUND
Meningeal carcinomatosis (MC) is an uncommon but aggressive complication of advanced breast cancer with a recently increasing incidence. Although the prognosis is extremely poor for MC patients, early diagnosis and appropriate treatment are important.
SUBJECTS AND METHODS
We reviewed 8 cases of MC from breast cancer at Kyoto University Hospital from 1990 to 1999. The median age was 51.5 years. All patients had widespread systemic metastases when diagnosed with MC. clinical symptoms were categorized into 3 groups: cranial nerve symptoms, spinal nerve symptoms, and other symptoms. Imaging studies were positive for MC in only 4 patients. Initial CSF cytology studies were positive in 4 patients, and repeated CSF cytology yielded positive results in the remaining 4 patients. Thus the median interval between the onset of any clinical symptom of MC and the initiation of treatment was 22.5 days (range 7 to 120 days ). All patients received whole brain radiotherapy (WBRT). Four patients were given intrathecal chemotherapy and/or intrathecal immunotherapy in addition to WBRT.
RESULTS
Improvement of cranial nerve symptoms, spinal nerve symptoms, and other symptoms were observed in 3/5, 1/3, and 5/7 patients, respectively. Patients with cranial nerve symptoms who started WBRT within 29 days of the onset of the symptoms showed at least partial recovery whereas patients who started WBRT later showed no recovery. The median survival was 123 days (53 to 310 days). MC was the direct cause of death in 1 of 8 patients.
CONCLUSION
When MC is clinically suspected, neither a negative imaging study nor a single negative CSF cytology can rule out MC. Prompt initiation of WBRT with or without intrathecal chemotherapy may be important for recovery from cranial nerve symptoms.
