Grade 1 glioma (low-grade glioma): Grade 1 gliomas are usually occur in children and teenagers. They are the most slow-growing (low-grade) form of glioma brain tumour and carry the longest prognosis. The most common form of low-grade glioma is a pilocytic astrocytoma , which rarely progresses to a higher grade and can sometimes be completely removed by surgery .

High-grade gliomas are highly vascular tumors and have a tendency to infiltrate diffusely. They have extensive areas of necrosis and hypoxia. Often, tumor growth causes a breakdown of the blood–brain barrier in the vicinity of the tumor. As a rule, high-grade gliomas almost always grow back even after complete surgical excision, so are commonly called recurrent cancer of the brain.

High grade glioma

Glioblastoma multiforme (GBM) is the most common of malignant primary brain tumors in adults and is one of a group of tumors referred to as gliomas. Classified as a Grade IV (most serious) astrocytoma, GBM develops from the lineage of star-shaped glial cells, called astrocytes, support nerve cells. Summary: Surgery, radiation, and chemotherapy remain the standard treatment options for patients with high-grade gliomas. Despite aggressive treatment, these tumors progress, and overall outcomes have not changed much in the past decade. However, our understanding of the disease is improving, and newer therapies appear promising.

Astrocytomas are the most common type of glioma in both adults and children. Astrocytomas can be low grade (slow growing) or high grade (fast growing). Low grade astrocytomas (grade 1 and grade 2) are more common in children and young adults. High grade tumours (grade 3 … High-grade gliomas are not surgically curable, because of their extensive infiltration.
