In brief: Tumor grading
Grading of tumors is a way of "standardizing" the type of cancer, and thereby improving consistency of treatment between treating doctors/institutions.
In gliomas as in other sites, a higher grade also implies a more aggressive tumor and potentially a poorer prognosis. However, some high grade tumors can be curable, whereas low grade tumors tend to linger but not respond to treatments.

In brief: GBM
Is considered stage iv, and gliosarcoma is pathologically different but clinically identical.
..Short survival, no cures, and similar treatment (resection, chemo and radiotherapy). The lower grades iii= anaplastic astrocution, and i/ii astrocytoma, oligodendroglioma. Hope this helps.

In brief: Classification
The 2007 world health organization scheme is the most widely accepted approach to classifying gliomas.
Malignant or high-grade gliomas are either grade iii or grade iv. Glioblastoma (gbm) is defined as grade IV in this system.
