The International Classification of Diseases for Oncology (ICD-O) is a domain-specific extension of the International Statistical Classification of Diseases and Related Health Problems for tumor diseases. This classification is widely used by cancer registries. It is currently in its third revision (ICD-O-3). ICD-10 includes a list of ...
Pediatric brain cancer is the second-leading cause of childhood cancer death, just after leukemia. Recent trends suggest that the rate of overall CNS tumor diagnosis is increasing by about 2.7% per year. As diagnostic techniques using genetic markers improve and are used more often, the proportion of AT/RT diagnoses is expected to increase.
The causes of CNS tumors are poorly understood. A few risk factors are known, including radiation exposure, genetic disorder, a family history of CNS tumors, immunodeficiency, stress and a history of previous cancers. As with all cancers, the risk of developing a CNS tumor increases with age. [10]

Dysembryoplastic neuroepithelial tumour (DNT, DNET) is a type of brain tumor.Most commonly found in the temporal lobe, DNTs have been classified as benign tumours. [1] These are glioneuronal tumours comprising both glial and neuron cells and often have ties to focal cortical dysplasia.
Gliosarcoma is a rare type of glioma, a cancer of the brain that comes from glial, or supportive, brain cells, as opposed to the neural brain cells. Gliosarcoma is a malignant cancer, and is defined as a glioblastoma consisting of gliomatous and sarcomatous components. [3]
Hemangioblastomas usually occur in adults, yet tumors may appear in VHL syndrome at much younger ages. Men and women are approximately at the same risk. Although they can occur in any section of the central nervous system, they usually occur in either side of the cerebellum, the brain stem or the spinal cord. [2] [7]
OMIM currently includes "Turcot syndrome" under Mismatch repair cancer syndrome. Turcot syndrome is the association between familial polyposis of the colon and brain tumors [8] like medulloblastoma, malignant glioma. It was first reported by Canadian surgeon Jacques Turcot (1914-1977 ) et al. in 1959 and hence carries the first author's name. [9]
