Vaccine for Patients With Newly Diagnosed or Recurrent Low-Grade Glioma

PRIMARY OBJECTIVES: I. To determine the 5-year progression-free survival (PFS), using intradermal injections of autologous dendritic cells harvested from peripheral blood precursors and pulsed (co-cultured) with tumor lysate derived from surgical tissues in patients with low-grade gliomas. SECONDARY OBJECTIVES: I. To monitor overall survival (OS), and cellular immune responses in brain tumor patients injected with tumor lysate-pulsed dendritic cells. OUTLINE: Patients receive tumor lysate-pulsed autologous dendritic cell vaccine intradermally (ID) on days 0, 14, and 28.
