 The purpose of this study is to determine if it is possible to make and administer safely a vaccine against glioblastoma by using information gained from specific characteristics of the participants tumor. It is known that glioblastomas have mutations changes in genetic material that are specific to an individual patients tumor. These mutations can cause the tumor cells to produce proteins that appear very different from the bodys own cells. It is possible that these proteins used in a vaccine may induce strong immune responses, which may help the body fight any tumor cells that could cause the glioblastoma to come back in the future.
