American Brain Tumor Association Primer

Sunday, September 29th, 2002

The American Brain Tumor Association has put together an excellent introductory resource on brain tumors.  Information on the following tumor types is excerpted (in quotes) from the primer.  Please refer directly to the American Brain Tumor Association Primer for the document in it’s entirety. 

ABTA Primer-Chondrosarcoma

Sunday, September 29th, 2002

The American Brain Tumor Association Primer offers the following information on Chondrosarcoma. 

“CHONDROSARCOMA

This very rare tumor arises from bone and is composed of cartilage. It is the malignant variant of the benign chondroma (described above) and tends to spread locally, staying within the same general area. This tumor is generally slow growing and rarely metastasizes, or spreads, to areas farther away. This tumor is most commonly found in the sphenoid bone – the boney ridge running along the back of the eyes – or near the clivus, a boney area at the base of the skull. The chondrosarcoma is more common in adult males.

Standard treatment is surgical removal which might be followed with radiation therapy. Those with a chondrosarcoma may also be eligible for treatment in a clinical trial – an organized research study. Those studies can be found through the Cancer Information Service at 800-422-6237.”

ASTROCYTOMA

 

Astrocytomas are tumors that arise from astrocytes – cells that make up the “glue-like” or supportive  tissue of the brain. These cells are named for their star‑like shape. About 60% of all primary brain tumors are astrocytomas. These tumors are “graded” by the pathologist to indicate how normal, or how abnormal, the cells of the tumor look. Grade I astrocytomas have slightly unusual looking cells; the cells of a grade IV astrocytoma are very abnormal in appearance. The astrocytoma section below describes the various grades of these tumors. The list begins with grade I tumors and progresses through grade IV astrocytomas.

Sometimes, terms describing the location or the appearance of an astrocytoma may be attached to it’s name. For example, a butterfly glioma is a high grade astrocytoma that has spread through both sides of the brain, causing a “butterfly” appearance on scans. A cerebellar astrocytoma is an astrocytoma found in the cerebellum of the brain.”

 

 

 

For Patients-Acoustic Neuroma

ACOUSTIC NEUROMA
    ALSO CALLED NEURILEMMOMA, VESTIBULAR SCHWANNOMA OR NEURINOMA

The acoustic neuroma is a benign tumor of the nerve of hearing (the 8th cranial nerve). It is located in the angle between the cerebellum and the pons, in the posterior fossa (the back of the skull). This tumor usually grows very slowly.
 

 
Acoustic neuromas typically occur in adults, particularly in their middle years. Females are twice as likely to have this tumor as males. Acoustic neuromas account for fewer than 7.5% of all primary brain tumors.
 
Tumors on both sides (bilateral) are rare, and tend to be familial. They are almost always associated with neurofibromatosis 2, a hereditary condition. The malignant form of this tumor, malignant peripheral nerve sheath tumor (MPNST), is extremely rare.
 
Common symptoms are one-sided hearing loss and buzzing or ringing in the ear. Dizziness may also occur, but is less common. If the tumor also affects the facial nerve (the 7th cranial nerve) located next to the 8th nerve, facial paralysis can occur. Other symptoms include difficulty in swallowing, impaired eye movement, taste disturbances, and unsteadiness.
 
Total removal using microsurgical techniques is often possible. Stereotactic radiosurgery might be used as an alternate to surgery for some patients.
