In childhood brain and spinal cord tumors, treatment options are based on several factors.
Staging is the process used to find how much cancer there is and if cancer has spread within the brain, spinal cord, or to other parts of the body. It is important to know the stage in order to plan cancer treatment.
In childhood brain and spinal cord tumors, there is no standard staging system. Instead, the plan for cancer treatment depends on several factors:
The information from tests and procedures done to detect (find) childhood brain and spinal cord tumors is used to determine the tumor risk group.
After the tumor is removed in surgery, some of the tests used to detect childhood brain and spinal cord tumors are repeated to help determine the tumor risk group (see the General Information section). This is to find out how much tumor remains after surgery. Other tests and procedures may be done to find out if cancer has spread:
A procedure used to collect cerebrospinal fluid from the spinal column. This is done by placing a needle into the spinal column. Lumbar puncture is usually not used to stage childhood spinal cord tumors. This procedure is also called an LP or spinal tap.
Lumbar puncture. A patient lies in a curled position on a table. After a small area on the lower back is numbed, a spinal needle (a long, thin needle) is inserted into the lower part of the spinal column to remove cerebrospinal fluid (CSF, shown in blue). The fluid may be sent to a laboratory for testing.
A procedure to check if there are rapidly dividing cells, such as cancer cells, in the bone. A very small amount of radioactive material is injected into a vein and travels through the bloodstream. The radioact...
