Vaccine Therapy in Treating Patients Undergoing Surgery for Recurrent Glioblastoma Multiforme
RATIONALE: Vaccines made from a person's tumor cells and dendritic cells may help the body build an effective immune response to kill tumor cells.
PURPOSE: This phase I trial is studying the side effects of vaccine therapy in treating patients undergoing surgery for recurrent glioblastoma multiforme (GBM).

Experimental: BTSC mRNA-loaded DCs
BTSC mRNA-loaded DCs administered intradermally weekly for first 3 vaccines, then monthly until progression or withdrawal.
Biological: BTSC mRNA-loaded DCs
An escalating total dose of BTSC mRNA-loaded DCs (2x10^6, 5x10^6, and 2x10^7 per vaccination) will be evaluated for purpose of establishing a maximum tolerated dose (MTD) and a dose-limiting toxicity (DLT).
- To evaluate the feasibility and safety of an autologous brain tumor stem cell messenger ribonucleic acid (mRNA)-loaded dendritic cell vaccine in adult patients with recurrent glioblastoma multiforme.
- To assess humoral and cellular immune responses to vaccination.
- To compare the proportion of vaccinated patients alive at 6 months from the time of surgery for recurrent tumor with matched historical cohorts.
OUTLINE: Patients undergo surgical resection of tumor. Tumor tissue samples are collected to isolate brain tumor stem cells (BTSCs) and for extraction and amplification of BTSC-specific mRNA. Within 4 weeks after surgical resection, patients undergo leukapheresis over 4 hours to generate dendritic cells (DCs). Patients also undergo leukapheresis at 1 week after the third vaccination and then at least every 3 months as needed for generation of additional DCs.
Patients receive autologous BTSC mRNA-loaded DC vaccine intradermally once weekly for 3 weeks and then once monthly in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed periodically.
