Abstract: Glioma is the most common primary brain tumor in adults, among which glioblastoma (GBM) is the most malignant. At present, the therapeutic regimen for patients with glioma mainly includes surgery, radiotherapy, and chemotherapy. However, the treatment strategy for elderly patients with GBM often varies because of their characteristics. A systematic and comprehensive assessment before the operation will be helpful to summarize clinical characteristics of elderly patients with GBM, and can provide clinicians with more comprehensive clinical information in order to evaluate the patient's tolerance to surgery and predict the prognosis. Based on a systematic review of the latest research, this expert consensus summarizes the most widely used and studied tools of preoperative assessment of glioma, and initially establishes a preoperative evaluation system for elderly patients with glioma in China.
