Meningiomas with malignant components include grade II meningiomas (GIIM, the most common ones) and grade III meningiomas (GIIIM). They represent 5-35% of all meningiomas. Histological diagnosis of GIIM criteria were changed in 2007 and might be viewed by some as being quite subjective. "Standards of care" and consensus do not exist for GIIM, particularly in regards to performing, or not, radiotherapy after surgery. One other limitation in the literature is lack of data on health-related quality of life (HRQoL). Clinical trials for GIIM are very difficult to conduct. No results have been made available. Here, we propose to study clinical, pathological, radiological and therapeutic factors of an exhaustive population of GIIM and GIIIM patients, at national level. The main objective (for GIIM) is to assess the impact of postoperative radiotherapy, or the absence of postoperative radiotherapy, on overall survival and on quality of life
