Brain Tumor - Metastatic Clinical Trial
Official title:
A Randomized Trial Evaluating GLIADEL Compared to Stereotactic Radiosurgery in Subjects With Metastatic Brain Disease
This study is being done to see if adding GLIADEL to the site where the tumor was removed works as well as just having the tumor removed with radiation treatment done within six weeks after the surgery to keep the cancer from coming back.
This study is being done to assess the efficacy of GLIADEL (a local chemotherapy) in preventing local recurrence of a metastatic brain tumor compared to stereotactic radiosurgery (SRS) after resection. 100 Adult subjects with one to four metastatic brain tumors with one tumor needing resection will be enrolled. Subjects with prior radiation, lymphoma, small cell, germ cell, unknown primary, or anaplastic thyroid diagnoses will be ineligible. Life expectancy should be greater than 3 months. Subjects will be randomized at the time of surgery to 1) GLIADEL placement at the time of resection or 2) SRS post-operatively to the resection cavity. Any other tumors (up to three) will have SRS as their primary treatment after surgery. SRS will take place within 6 weeks from surgery. Subjects will be evaluated pre-operatively with MRI brain and neuropsychological testing and will have immediate post-op MRI for extent of resection (EOR) determination. Subjects will have SRS to the resection cavity if no GLIADEL was placed and all will have SRS to any other lesions. They will be followed at set intervals to evaluate for local recurrence and neurocognitive changes. The genome of the metastatic brain tumor will be compared to their primary and germline for identification of alterations. ;
