An astrocytic tumor begins in star-shaped brain cells called astrocytes, which help keep nerve cells healthy. An astrocyte is a type of glial cell and is sometimes called a glioma. Astrocytic tumors include the following:
• Brain stem glioma:
A brain stem glioma forms in the brain stem, which is the part of the brain connected to the spinal cord. It is often a high-grade tumor, which spreads widely through the brain stem and is hard to cure. A brain stem glioma rarely occurs in adults.
• Pineal astrocytic tumor:
A pineal astrocytic tumor forms in tissue around the pineal gland and may be any grade. The pineal gland is a tiny organ in the brain that makes melatonin, a hormone that helps control the sleeping and waking cycle.
• Pilocytic astrocytoma (grade I):
A pilocytic astrocytoma grows slowly in the brain or spinal cord. It may be in the form of a cyst and rarely spreads into nearby tissues. This type of tumor is most common in children and young adults and in people with neurofibromatosis type 1 (NF1). A pilocytic astrocytoma rarely causes death.
• Diffuse astrocytoma (grade II):
A diffuse astrocytoma grows slowly, but often spreads into nearby tissues. Sometimes a diffuse astrocytoma progresses to a higher grade and becomes an anaplastic astrocytoma or a glioblastoma. A diffuse astrocytoma can form in any part of the brain but most often forms in the cerebrum. It is most common in young adults and in people with Li-Fraumeni syndrome. It is also called a low-grade diffuse astrocytoma.
• Anaplastic astrocytoma (grade III):
An anaplastic astrocytoma grows quickly and spreads into nearby tissues. An anaplastic astrocytoma may progress to a higher grade and become a glioblastoma. An anaplastic astrocytoma forms most often in the cerebrum and is most common in adults. An anaplastic astrocytoma is also called a malignant astrocytoma or high-grade astrocytoma.
• Glioblastoma (grade IV):
A glioblastoma grows and spreads very quickly. A glioblastoma forms most often in the cerebrum. This type of tumor is most common in adults. This type of tumor has a poor prognosis. It is also called glioblastoma multiforme.
An oligodendroglial tumor begins in brain cells called oligodendrocytes, which help keep nerve cells healthy. Oligodendrocytes are a type of glial cell and are sometimes called a glioma. Grades of oligodendroglial tumors include the following:
• Oligodendroglioma (grade II):
An oligodendroglioma grows and spreads slowly and the tumor cells look very much like normal cells. This type of tumor most often ...
