Predictive Factors of Recurrence of Non Functioning Pituitary Adenomas : a Retrospective Study of 220 Patients in the Reims University Hospital, France
Non functioning pituitary adenomas (NFPAs) are the most common pituitary adenomas. Their
 growth is usually slow and diagnosis is often made in the context of masse effect .The

 radiotherapy. Nowadays, there is no clinical or histological prognostic factor to allow an
 individualized follow-up and recurrence could happen 10 or 15 years after the first surgery.
 In this study, the investigators evaluate NFPAs recurrence rate after surgery and try to find
 predictive factors of recurrence to personalized the follow-up of each patient.
