[Risk of increased malignancy a reason for follow-up of low malignancy grade glioma. Early identification of high-risk patients is the key to good care].

Management of patients with low-grade gliomas remains a challenge. Controversies exist regarding the value of surgery and radiotherapy as well as the right timing of these treatments with respect to disease course. Several factors have been shown to have a positive correlation with better outcome, involving tumor size and localization, age and clinical condition of the patient on presentation, and epileptic seizures as a single symptom. The absence of contrast enhancement on CT-scans is also a favorable prognostic factor. Taking into account the results of these studies as well as our own experience, we suggest some strategies for the management of patients with low-grade gliomas. The importance of identifying "high-risk" patients by systematic clinical and radiological follow-up is discussed.
