Study in Leptomeningeal Metastases of Breast Cancer
France51 participantsStarted 2017-01-06
Plain-language summary
Breast cancer (BC) is the most frequent cause of leptomeningeal metastases (LM) .As for brain parenchymal metastases, the incidence of LM seems to be increasing, due to the growing incidence of metastatic BC, the improvement of survival and the poor diffusion of therapeutic agents into the central nervous system (CNS). Several prognostic factors have been identified, including the age at diagnosis, the functional and neurological status, the delay between the diagnosis of cancer and that of LM. The survival of patients is poor, less than 6 months in most published series. Several neuronal biomarkers could also be good candidates, such as the neurogranin CSF and/or serum levels or the CNS neurofilaments (NF), that seem to be a good reflect of axonal injury and neuronal loss. CNS NF have been investigated in several neurological diseases including Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis and multiple sclerosis, but not yet in CNS metastases. Indeed, the creation of a clinico-biological collection seems to be of high value in order to investigate future biomarkers of interest
