1 MANAGEMENT N OF PRIMARY BRAIN TUMOURS IN THE ELDERLY Meningioma, Glioma, Lymphoma Cornu Ph, Keime-Guibert F, Hoang-Xuan K, Pierga JY, Delattre JY Neuro-oncology Group of Pitie-Salpetriere hospital-paris-france MANAGEMENT OF PRIMARY BRAIN TUMOURS IN THE ELDERLY Meningioma 15 to % of brain tumours Elderly people ~ 5% (Kuru et al ) BENIGN tumour surgical resection RISK : morbidity / mortality Page 1

Neurological conditions 2.General health conditions 3.Tumour location Page 8
