  3. 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:[ 1 ] 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 ...

  4. Summary of Evidence

    Note: Separate PDQ summaries on Neuroblastoma Treatment and Levels of Evidence for Cancer Screening and Prevention Studies are also available. Intervention Screening,usually at age 6 months,for urine vanillylmandelic acid and homovanillic acid,which are metabolites of the hormones norepinephrine and dopamine. Benefits Based on solid evidence,screening for neuroblastoma does not lead to ...

  5. Cellular Classification

    One clinicopathologic staging system involves evaluation of tumor specimens obtained prior to therapy for the amount of stromal development,the degree of neuroblastic maturation,and the mitosis-karyorrhexis index of the neuroblastic cells.[ 1,2 ] Favorable and unfavorable prognoses are defined on the bases of these histologic parameters and on patient age. The prognostic significance of this ...

  6. Stages of Childhood Brain Stem Glioma

    After the childhood brain stem glioma has been removed,tests are done to find out if there is tumor remaining. The extent or spread of cancer is usually described as stages. For childhood brain stem glioma,the tumors are described by type: Diffuse intrinsic pontine glioma is a tumor that has spread widely throughout the brain stem. Focal or low-grade glioma is a tumor that is localized to ...

  7. Thyrotropin-Producing Tumors Treatment

    Standard Treatment Options for Thyrotropin-Producing TumorsStandard treatment options for thyrotropin-producing tumors include the following:Surgery (usually a transsphenoidal approach), with or without adjuvant radiation therapy.[1,2] Somatostatin analogues, such as octreotide.[3,4]Transsphenoidal surgery is the treatment of choice for patients with thyrotropic adenomas.[1] Adjuvant radiation therapy may be employed when surgery is known to be noncurative even if the patient is still euthyroid because relapse is inevitable, and the full effect of radiation therapy requires months or years. Medical therapy may be required for patients who still have hyperthyroid symptoms despite surgery and external radiation. Somatostatin analogues are the drugs of choice for treatment; however, the efficacy of treatment may wane with time.[1,2,3,4]Current Clinical TrialsCheck for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with pituitary tumor. The

  8. Stage Information for Pituitary Tumors

    As with other tumors of the central nervous system (CNS), no tumor, nodes, metastases-based American Joint Committee on Cancer classification and staging system for pituitary tumors exists.[1] Pituitary tumors are classified according to size and divided into microadenomas (i.e., the greatest diameter is <10 mm) and macroadenomas (i.e., the greatest diameter is ≥I0 mm).[2] Most pituitary adenomas are microadenomas. The most widely used radioanatomical classification was based primarily on a neuroradiological examination including skull x-rays, pneumoencephalography, polytomography, and carotid angiography.[3] Subsequently validated by the application of more accurate magnetic resonance imaging (MRI) and computed tomography, this radioanatomical classification places adenomas into 1 of 4 grades (I–IV) and has been augmented by additional studies including immunohistochemistry and electron microscopy.[4] Currently, MRI is considered the imaging modality of choice for the diagnosis
