Malignant Childhood Central Nervous System Neoplasm Clinical Trial
Official title:
Determination of A-Protein Levels in Adult and Pediatric Brain Tumor Patients
The purpose of this study is to evaluate the sensitivity and specificity of "A-PROTEIN" levels in patients with brain tumors. A-PROTEIN levels will be analyzed both pre and post treatment. Levels in blood and/or cerebrospinal fluid (CSF) will be analyzed and correlated with the underlying diagnosis and outcome.
- Patients will be identified at the time of presentation to their neurologist,
neurosurgeon or oncologist.
- Blood or cerebrospinal fluid will be collected for this study only when they are being
collected for other reasons before and after each surgery. Samples will also be
collected after any event such as significant change in symptoms or radiographic
progression.
- Once the patients condition has been stabilized, samples will be take at regular
intervals of >= 1 month. The duration of this study is 24 months.
