Practice parameters in adults with suspected or known supratentorial nonoptic pathway low-grade glioma.
In January 1994, the Guidelines and Outcomes Committee of the American Association of Neurological Surgeons (AANS) issued a charge to develop practice parameters to treat adult patients with low-grade glioma (LGG). This area of study was chosen because of a similar interest on the part of the American Academy of Neurology (AAN) and the controversy surrounding the management of such patients.
