Brain stem gliomas have relatively poor prognoses that correlate with histology (when biopsies are performed), location, and extent of tumor. The overall median survival time of patients in studies has been 44 to 74 weeks.[1,2,3,4,5] The best results have been attained with hyperfractionated radiation therapy.
There is no standard staging system for central nervous system atypical teratoid/rhabdoid tumor.
The extent or spread of cancer is usually described as stages. There is no standard staging system for central nervous systematypical teratoid/rhabdoid tumor. This tumor is classified as newly diagnosed or recurrent. Treatment depends on how much cancer remains after surgery and the age of the child. Results from the following procedures are used to plan treatment:
MRI (magnetic resonance...
At recurrence, patients should be considered for clinical trials that evaluate new drugs and biological response modifiers.[7,8]
Current Clinical Trials
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with adult brain stem glioma. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.
General information about clinical trials is also available from the NCI Web site.
