A central nervous system tumor (CNS tumor) is an abnormal growth of cells from the tissues of the brain or spinal cord. [1] CNS tumor is a generic term encompassing over 120 distinct tumor types. [2] Common symptoms of CNS tumors include vomiting, headache, changes in vision, nausea, and seizures. [3]
Treatment for a central neurocytoma typically involves surgical removal, with an approximate 1 in 5 chance of recurrence. [2] Central neurocytomas are classified as a grade II tumor under the World Health Organization's classification of tumors of the nervous system. [3]
A nervous system tumor is a tumor that arises within the nervous system, either the central nervous system (CNS) or the peripheral nervous system (PNS). [1] [2] Nervous system primary tumors include various types of brain tumor and spinal tumors, such as gliomas, and meningiomas (of the CNS), and schwannomas (of the PNS) and can be either benign or malignant.
Radiotherapy is an important treatment for central nervous system tumors and has been demonstrated to extend survival and improve the quality of life for patients with many of the primary and metastatic brain tumors. [7] Chemotherapy Chemotherapy, or the use of drugs in the treatment of cancer, can lead to the long-term control of many ...
A nervous system neoplasm is a tumor that arises within the nervous system, either the central nervous system (CNS) or the peripheral nervous system (PNS). [ 1 ] [ 2 ] . Nervous system neoplasms include various types of brain and spinal cord tumors, such as gliomas , and meningiomas (of the CNS), and schwannomas (of the PNS) and can be either ...
CNS metastasis is the spread and proliferation of cancer cells from their original tumour to form secondary tumours in portions of the central nervous system. [1] The process of tumour cells invading distant tissue is complex and obscure, but modern technology has permitted an enhanced detection of metastasis.
Central Nervous System Prophylaxis, or CNS prophylaxis, is a type of chemotherapy for patients at risk of cancer metastasis into the central nervous system (CNS). [1] Prophylaxis originated from the Greek word “phulaxis”, meaning the act of guarding. [ 2 ]
The World Health Organization has classified the central nervous system primitive neuroectodermal tumors into five subtypes: neuroblastoma, ganglioneuroblastoma, medulloepithelioma, ependymoblastoma, and not otherwise specified PNET. [1] The last one encompasses the PNETs with varying characteristics that hasn't been well defined yet. [1]
