Purpose of This SummaryThis PDQ cancer information summary for health professionals provides comprehensive, peer-reviewed, evidence-based information about the treatment of childhood brain stem glioma. It is intended as a resource to inform and assist clinicians who care for cancer patients. It does not provide formal guidelines or recommendations for making health care decisions.Reviewers and UpdatesThis summary is reviewed regularly and updated as necessary by the PDQ Pediatric Treatment Editorial Board, which is editorially independent of the National Cancer Institute (NCI). The summary reflects an independent review of the literature and does not represent a policy statement of NCI or the National Institutes of Health (NIH). Board members review recently published articles each month to determine whether an article should:be discussed at a meeting,be cited with text, orreplace or update an existing article that is already cited.Changes to the summaries are made through a
SurgeryRe-resection of recurrent brain tumors is used in some patients. However, the majority of patients do not qualify because of a deteriorating condition or technically inoperable tumors. The evidence is limited to noncontrolled studies and case series on patients who are healthy enough and have small enough tumors to technically debulk. The impact of reoperation versus patient selection on survival is not known.Localized ChemotherapyCarmustine wafers have been investigated in the setting of recurrent malignant gliomas, but the impact on survival is less clear than at the time of initial diagnosis and resection. In a multicenter randomized, placebo-controlled trial, 222 patients with recurrent malignant primary brain tumors requiring reoperation were randomly assigned to receive implanted carmustine wafers or placebo biodegradable wafers. Approximately half of the patients had received prior systemic chemotherapy. The two treatment groups were well balanced at baseline.
The PDQ childhood brain tumor treatment summaries are organized primarily according to the World Health Organization (WHO) classification of nervous system tumors.[1,2] For a full description of the classification of nervous system tumors and a link to the corresponding treatment summary for each type of brain tumor, refer to the PDQ summary on Childhood Brain and Spinal Cord Tumors Treatment Overview.Dramatic improvements in survival have been achieved for children and adolescents with cancer. Between 1975 and 2002, childhood cancer mortality decreased by more than 50%. Childhood and adolescent cancer survivors require close follow-up because cancer therapy side effects may persist or develop months or years after treatment. Refer to the PDQ summary on Late Effects of Treatment for Childhood Cancer for specific information about the incidence, type, and monitoring of late effects in childhood and adolescent cancer survivors.Primary brain tumors are a diverse group of
