Official title
EGF Polymorphisms and Gliomagenesis
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will examine tissue from gliomas (a type of brain tumor) removed during surgery for gene mutations, or changes, thought to be involved in tumor formation and growth. One common gene mutation causes the receptor for a protein called epidermal growth factor (EGF) to be in an active state all of the time, allowing uncontrolled cell growth that can lead to tumor formation. This study will analyze blood and tumor tissue samples from patients with gliomas for: * Changes in the EGF gene in the tumor * Changes in other genes, such as that for the EGF receptor (EGFR) * Changes in levels of EGF and EGFR, and in other proteins and genes that respond to changes in the levels of these proteins in the tumor * Changes in the EGF gene and protein in the blood The study will also determine if production of EGF and EGFR obtained from glioma and from blood cells derived from the tumor can be altered in the laboratory to grow indefinitely in culture. Patients between 18 and 75 years of age with a brain tumor that requires surgical treatment may be eligible for this study. Participants will be admitted to the NIH Clinical Center for about 3 to 10 days. They will have a physical and neurological examination, blood and urine tests, other tests, if medically necessary, and will be evaluated and prepared for surgery. During surgery, as much of the tumor as possible will be removed. A small amount of the tumor tissue will be collected for this study. No tissue will be removed for this study that would not otherwise have been removed. Some of the tissue will be used to culture glioma cells and the rest will be frozen and stored for examination, as described above. If any normal-appearing brain tissue is removed during surgery in order to enhance safety in removing the tumor, the normal tissue will be studied as well. Brain tissue that appears normal will not be removed strictly for research. During surgery and the day after surgery, a blood sample will be drawn from a catheter (plastic tube) that was placed in an artery or vein for surgery. If catheters are no longer in place, blood will be drawn through a needle in a vein.
