The concept of grading of the tumors of the central nervous system, agreeing for such the regulation of the "progressiveness" of these neoplasias (from benign and localized tumors to malignant and infiltrating tumors), dates back to 1926 and was introduced by P. Bailey and H. Cushing,[1]
in the elaboration of what turned out the first systematic classification of gliomas.[2]
In the following, the grading systems present in the current literature are introduced. Then, through a table, the more relevant are compared.
