Overview
Risk factors for NM includes late stage cancer, primary brain tumor and intracranial surgery.
Risk Factors
Factors that have been known to increase the risk of neoplastic meningitis involves:[1]
- Brain metastasis is one of the more obvious risk factors for neoplastic meningitis. Coexisting brain metastasis are associated with neoplastic meningitis in breast cancer (33-54%), lung cancer (56-82%) and melanoma (87-96%).
- Primary brain cancer always poses a risk for the development of neoplastic meningitis. It is diagnosed in 1-2% of cases of ependymoma, medulloblastoma, germinoma and glioblastoma combined.
- Brain surgery increases the chance of developing neoplastic meningitis. It has been observed after resection of brain tumor (particularly piecemeal resection vs en-block resection) particularly tumors located in the cerebellum. Other cranial surgeries done with involvement of ventricular system manipulation in a patient with known brain metastasis increases the risk. Furthermore, the incidence of neoplastic meningitis seem higher in patient treated with surgery followed by stereotactic radiosurgery compared with radiosurgery alone.
- ER-, PR-positivity in beast cancer increases incidence of neoplastic meningitis. Triple negative breast cancer and the HER2/neu gene positivity displays tropism for CNS metastasis. Among the histologic subtypes of breast cancer, lobular carcinoma demonstrated the highest prevalence for neoplastic meningitis.
