Childhood Central Nervous System Atypical Teratoid/Rhabdoid Tumor Treatment (PDQ®): Treatment - Patient Information [NCI] - Stages of Central Nervous System Atypical Teratoid / Rhabdoid Tumor
There is no standard staging system for central nervous system atypical teratoid/rhabdoid tumor.
The extent or spread of cancer is usually described as stages. There is no standard staging system for central nervous system atypical teratoid/rhabdoid tumor. This tumor is classified as newly diagnosed or recurrent. Treatment depends on how much cancer remains after surgery and the age of the child. Results from the following procedures are used to plan treatment:
MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the brain and spinal cord. This procedure is also called nuclear magnetic resonance imaging (NMRI).
Lumbar puncture: A procedure used to collect cerebrospinal fluid from the spinal column. This is done by placing a needle into the spinal column. This procedure is also called an LP or spinal tap.
There are three ways that cancer spreads in the body.
The three ways that cancer spreads in the body are:
Through tissue. Cancer invades the surrounding normal tissue.
Through the lymph system. Cancer invades the lymph system and travels through the lymph vessels to other places in the body.
Through the blood. Cancer invades the veins and capillaries and travels through the blood to other places in the body.
When cancer cells break away from the primary (original) tumor and travel through the lymph or blood to other places in the body, another (secondary) tumor may form. This process is called metastasis. The secondary (metastatic) tumor is the same type of cancer as the primary tumor. For example, if breast cancer spreads to the bones, the cancer cells in the bones are actually breast cancer cells. The disease is metastatic breast cancer, not bone cancer.
