NovoTTF-200A Device in Treating Patients With Newly Diagnosed High Risk Oligodendroglioma

PRIMARY OBJECTIVES: I. To describe the safety and tolerability of the TTFields treatment in patients with newly diagnosed high risk oligodendroglioma following standard of care treatment. SECONDARY OBJECTIVES: I. To estimate the proportion of patients who tolerated 75% of treatment goal at months 6, 12, 24. II. To estimate the progression free survival time. III. To assess quality of life. IV. To assess whether or not there is a correlation between genomics and the efficacy of the TTFields treatment. OUTLINE: Beginning 4-8 weeks after standard of care treatment, patients wear NovoTTF-200A device over 18 hours daily (QD). Treatment continues for up to 24 months in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at 2 months and then monthly thereafter.
