[Neurosurgical multicenter study of cerebral metastases (Neurosurgical departments of Paris Beaujon, Paris Sainte-Anne, Strasbourg)].

We report a multicentric outcome study of cerebral metastases in 174 patients collected consecutively in three neurosurgical centers in France. Age and condition of patients allowed surgical operation; the sex ratio was 1.67. The revelation mode was usual. However tumoral hemorrhage frequency was 3.4%. Primitive cancers were usual cancers as in oncological series with a higher proportion of radioresistant metastases. Mean dimension was 30 mm with mean of 1. 25 metastases per patient. Supratentorial localization was more frequent and the metastasis revealed cancer in 40% of cases. Global median survival was 12.1 months. Factors correlated with the survival in our series of patients with cerebral metastases were: solitary cerebral metastasis, extracerebral extension of cancer, treatment of primitive cancer, complete excision and post operative cerebral radiotherapy.
