Glioblastoma pre (left) and post (right) resection. Surgery is the first stage of treatment of glioblastoma. An average GBM tumor contains 10 11 cells, which is on average reduced to 10 9 cells after surgery (a reduction of 99%). Benefits of surgery include resection for a pathological diagnosis, alleviation of symptoms related to mass effect ...

Gliomatosis cerebri is most often caused by glioblastoma, but can also arise from astrocytoma, oligodendroglioma or other types of diffuse glioma. [2] Other pathologies such as vasculitis , encephalitis or leukoencephalopathy may also cause similar radiological findings.
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.
John McCain suffers from a highly malignant form of cancer that spreads quickly due to its association with a large network of blood vessels in the brain.
Gliosarcoma is a rare type of glioma, a cancer of the brain that comes from glial, or supportive, brain cells, as opposed to the neural brain cells. Gliosarcoma is a malignant cancer, and is defined as a glioblastoma consisting of gliomatous and sarcomatous components. [3]
A glioma is a type of primary tumor that starts in the glial cells of the brain or spinal cord.They are cancerous but some are extremely slow to develop. [2] [3] Gliomas comprise about 30 percent of all brain tumors and central nervous system tumours, and 80 percent of all malignant brain tumours.
