(11, 15, 16) However, very few clinically significant mutations were reported in those studies. (11, 15, 16). There are limited studies with intracranial and spinal myxopapillary ependymomas Ependymoma is a primary tumor, which means that it starts in either the brain or spine. The brain and spine are part of the central nervous system (CNS). Primary brain and spinal cord tumors are typically grouped by where the cells start. CNS tumors associated with all three types of glial cells are recognized by the World Health Organization ... The value of histologic grading in determining the prognosis of ependymoma patients is controversial. 4,9,16,18,19,23-26 Compared with classic ependymoma, anaplastic ependymoma exhibits histologic evidence of advanced anaplasia, including nuclear atypia, marked mitotic activity, high cellularity, and microvascular proliferation or necrosis.CSI should be done if +CSF, +MRI neuroaxis, and ependymoblastoma histology. For all others, local RT is sufficient. What evidence supports the omission of CSI for anaplastic ependymomas after resection if there is no evidence of neuroaxial involvement?A clinicopathologic study of 81 patients with ependymomas and proposal of diagnostic criteria for anaplastic ependymoma.
