Childhood Brain and Spinal Cord Tumors Treatment Overview (PDQ®): Treatment - Patient Information [NCI] - General Information About Staging Childhood Brain and Spinal Cord Tumors
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 type of tumor and where the tumor formed in the brain.
- Whether the tumor is newly diagnosed or recurrent. A newly diagnosed brain or spinal cord tumor is one that has never been treated. A recurrent childhood brain or spinal cord tumor is one that has recurred (come back) after it has been treated. Childhood brain and spinal cord tumors may come back in the same place or in another part of the brain, or spinal cord. Sometimes they come back in another part of the body. The tumor may come back many years after first being treated. Tests and procedures, including biopsy, that were done to diagnose and stage the tumor may be done to find out if the tumor has recurred.
- The grade of the tumor. The grade of the tumor is based on how abnormal the cancer cells look under a microscope and how quickly the tumor is likely to grow and spread. It is important to know the grade of the tumor and if there were any cancer cells remaining after surgery in order to plan treatment. The grade of the tumor is not used to plan treatment for all types of brain and spinal cord tumors.
- The tumor risk group. Risk groups are either average risk and poor risk or low, intermediate, and high risk. The risk groups are based on the amount of tumor remaining after surgery, the spread of cancer cells within the brain and spinal cord or to other parts of the body, where the tumor has formed, and the age of the child. The risk group is not used to plan treatment for all types of brain and spinal cord tumors.
