Summary
This early phase I trial tests the safety and reliability of an investigational imaging technique called quantitative oblique back illumination microscopy (qOBM) during brain surgery for detecting brain tumors and brain tumor margins in patients with glioblastoma, astrocytoma, or oligodendroglioma. Surgical margins refer to the edge or border of the tissue removed in cancer surgery. qOBM may assist doctors in detecting brain tumor and its margins with surrounding normal tissue more safely and reliably in patients with glioblastoma, astrocytoma, or oligodendroglioma.
Objectives
PRIMARY OBJECTIVE:
I. To perform a first-in-human study to assess the ability of a quantitative oblique back illumination microscopy (qOBM) handheld device to safely and reliably image brain tumor pathology intraoperatively in-situ and in-vivo.
SECONDARY OBJECTIVES:
I. To characterize the biophysical and structural features that enable detection of bulk tumor and tumor margins, including infiltrative disease, with qOBM.
II. To develop qOBM imaging probes with multimodal capabilities (analog black and white and color imaging, fluorescent imaging) and with the potential to clearly reveal brain tumor margins ex vivo and in vivo during neurosurgical procedures.
OUTLINE:
Patients undergo craniotomy with intraoperative ex vivo and in situ tumor assessment with qOBM. Patients then undergo postoperative exam with computed tomography (CT) or magnetic resonance imaging (MRI) any of days 1-5 after surgery.
Eligibility
- Age >= 18 years
- Craniotomy is indicated for tumor management
- Surgery planned for 14 or fewer days from enrollment
- Evidence of a personally signed informed consent indicating that the subject is aware of the neoplastic nature of the disease and has been informed of the procedures to be followed, the experimental nature of the device evaluation, alternatives, potential risks and discomforts, potential benefits, and other pertinent aspects of study participation
- A newly discovered brain lesion requiring surgery whose imaging is consistent with a new glioblastoma, astrocytoma, or oligodendroglioma or with a progressive histologically proven glioblastoma, astrocytoma, or oligodendroglioma whose management requires surgery

**Clinical trials are research studies that involve people. These studies test new ways to prevent, detect, diagnose, or treat diseases. People who take part in cancer clinical trials have an opportunity to contribute to scientists’ knowledge about cancer and to help in the development of improved cancer treatments. They also receive state-of-the-art care from cancer experts...
