The Role of Neuropathology in the Management of Patients with Diffuse Low Grade Glioma: A Systematic Review and Evidence-Based Clinical Practice Guideline

This is a clinical practice guideline for the diagnosis and management of patients with diffuse low grade glioma. More specifically, the guideline addresses a number of questions related to the diagnosis and management of patients with diffuse low grade glioma including: what are the optimal neuropathological techniques to diagnose low-grade glioma in the adult; and, in adult patients with histologically-proven WHO grade II diffuse glioma, is MGMT promoter methylation testing warranted? If so, is there a preferred method? In addition to providing recommendations in response to questions like those stated above, the guideline also identifies key issues for future investigation such as the identification of distinct molecular characteristics.
