General Information About Childhood Brain and Spinal Cord Tumors
A childhood brain or spinal cord tumor is a disease in which abnormal cells form in the tissues of the brain or spinal cord. There are many types of childhood brain and spinal cord tumors. The tumors are formed by the abnormal growth of cells and may begin in different areas of the brain or spinal cord. Tumors may be benign (noncancerous) or malignant (cancerous). Together,the brain and ...

Changes to This Summary (05 / 14 / 2013)
The PDQ cancer information summaries are reviewed regularly and updated as new information becomes available. This section describes the latest changes made to this summary as of the date above. General Information About Adult Brain TumorsRevised text on factors used to diagnose brain metastases to include diagnostic procedures, including contrast magnetic resonance imaging (MRI) of the brain.Treatment Option OverviewAdded text to state that external-beam radiation therapy using either 3-dimensional conformal radiation therapy or intensity-modulated radiation therapy is considered an acceptable technique in radiation therapy delivery. Typically 2- to 3-cm margins on the MRI-based volumes to create the planning target volume are used. Dose escalation using radiosurgery has not improved outcomes.Added Souhami et al. as reference 15.Added Leptomeningeal carcinomatosis as a new subsection.Added text to state that a phase III randomized trial compared adjuvant whole-brain radiation therapy
Stages of Childhood Ependymoma
The area where the tumor is found and the child's age are used in place of a staging system to plan cancer treatment.Staging is the process used to find out how much cancer there is and if cancer has spread. It is important to know the stage in order to plan treatment. There is no standard staging system for childhood ependymoma. Instead, the plan for cancer treatment after surgery depends on the following: Whether any cancer cells remain after surgery.Whether the cancer has spread to other parts of the brain or spinal cord.The age of the child.The information from tests and procedures done to detect (find) childhood ependymoma is used to plan cancer treatment.Some of the tests used to detect childhood ependymoma are repeated after the tumor is removed by surgery. (See the General Information section.) This is to find out how much tumor remains after surgery. Another procedure that may be done to find out if cancer has spread is a lumbar puncture. A lumbar puncture is a procedure used
Adrenocorticotropic Hormone-Producing Pituitary Tumors Treatment
Standard Treatment Options for Adrenocorticotropic Hormone (ACTH)-Producing Pituitary TumorsStandard treatment options for ACTH-producing pituitary tumors include the following:Surgery (usually a transsphenoidal approach).[1,2,3]Surgery plus radiation therapy.[1,2,4]Radiation therapy.[1,2,4]Steroidogenesis inhibitors, including mitotane, metyrapone, ketoconazole, and aminoglutethimide.[1,2,5]For patients with corticotroph adenomas, transsphenoidal microsurgery is the treatment of choice.[1,2] Remission rates reported in most series are approximately 70% to 90%. In a series of 216 patients, who were operated on using a transsphenoidal approach, 75% experienced long-term remission, 21% experienced persistence of Cushing disease, and 9% had recurrence after the initial correction of the hypercortisolism. The average time interval for reoperation was 3.8 years. Seventy-nine percent of the tumors were microadenomas, and 18% were macroadenomas; 86% of the cases with microadenoma had
Histopathologic Classification of Childhood Ependymal Tumors
In the most recent World Health Organization (WHO) classification of brain tumors, ependymal tumors are classified into four main subtypes:Subependymoma (WHO Grade I).Myxopapillary ependymoma (WHO Grade I).Ependymoma (WHO Grade II). Variants include cellular, papillary, tanycytic, clear cell, and mixed.Anaplastic (also known as malignant) ependymoma (WHO Grade III).The subependymoma is a slow-growing benign neoplasm, typically attached to the ventricle wall, and is composed of glial tumor cell clusters embedded in a fibrillary matrix. The myxopapillary ependymoma arises almost exclusively in the location of the conus medullaris, cauda equina, and filum terminale of the spinal cord, and is characterized histologically by tumor cells arranged in a papillary manner around vascularized myxoid stromal cores.The ependymoma, which is considered a Grade II neoplasm originating from the walls of the ventricles or from the spinal canal, is composed of neoplastic ependymal cells.
