Light Scattering Spectroscopy to Determine Brain Tumors
NCT00067418 · View on ClinicalTrials.gov ↗
Study 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.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00067418
The ClinicalTrials.gov registry entry for NCT00067418 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 50 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute of Neurological Disorders and Stroke (NINDS), which has 339 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Epilepsy, Temporal Lobe appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00067418 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
