    Among the significant prognostic factors such as the patient's age, performance status, or tumor histopathology, the most important prognosticator for glioma patients is the degree of tumor removal. On the other hand, surgical removal should not induce aggravation of the patient's performance status. As a result, surgical planning for glioma should be carefully considered. However, there is no standard guide for preoperative planning at present. In this study, we tried to divide 390 gliomas into 5 stages according to the difficulty of surgery and then analyzed the relation between removal rate and each stage. The results demonstrated that the stage correlates with both the removal rate and the patient's survival. This grouping can be useful to discuss the feasibility of surgical planning among multiple neurosurgical institutions.
