5. Study Description

Brief Summary
This study will use light scattering spectroscopy (LSS) to analyze brain tissue removed from patients during brain surgery to determine if this new technology can be used to differentiate between normal and cancerous cells. LSS focuses light on cells or tissues, and the way that light is reflected back from the tissues provides information about the size of cells and the density of the cell nuclei (the part of the cell that contains the genes). Patients between 18 and 75 years of age with a known or suspected brain tumor and patients with temporal lobe epilepsy that does not respond to medication may be eligible for this study. (Examination of tissue from patients with epilepsy will allow comparison of tumor and non-tumor brain cells.) All patients must require surgery to treat their condition. Participants will be admitted to the Clinical Center for 3 to 10 days for physical and neurological examinations, blood and urine tests, and other tests needed to prepare for surgery. They will then undergo surgery. A small amount of tissue removed during surgery for pathological review will be collected for use in this study. Half of the tissue will be examined using LSS to help determine the size of the cell and its nucleus. Studies will be done to measure how many of the cells are actively dividing and which proteins are expressed more often in tumor cells compared with normal cells. This information may shed light on how tumor cells are different from normal cells. Participants may be contacted for up to 3 years to follow their health status.
Detailed Description
Optical spectroscopy for detection of brain tumors and tumor margins has been shown to be of use in distinguishing gliomas and metastatic tumor cells from surrounding white matter. Optical spectroscopy has the potential to provide immediate and accurate diagnostic information about the nature and quantity of neoplastic cells, in a minimally-or non-invasive fashion. We propose to use a new method of optical spectroscopy, polarized light-scattering spectroscopy (LSS), which permits discrimination of malignant cancer cells from normal brain cells by virtue of alterations in the cytoplasmic and nuclear ratios of these cells. Patients suspected of having, or with prior biopsy proof of, a WHO grade II-IV central nervous system (CNS) glial tumor(s); those with metastatic brain tumor; or patients with medically-refractory temporal lobe epilepsy with a presumed hippocampal source of seizures, who are seen in the Surgical Neurology Branch, NINDS, will be considered for entry into this study. Tissue samples of tumor or normal lateral temporal neocortex resected as part of standard care will be collected at surgery and utilized for research.
