Glioblastoma (GBM) is a challenging cancer with poor prognosis. The classical standard for treatment is safe resection, followed by concurrent chemoradiotherapy with subsequent adjuvant temozolomide (TMZ). Despite several attempts at different treatments, the 5-year survival rate remains poor. In recent years, with the continuous progress of treatment technology, tumor treating fields (TTFields) were preferable. The device could generate an intermediate frequency alternating electric field and induce apoptosis of some specific types of cancer cells with few toxic and side effects. TTFields induced apoptosis through multiple activations of the pathway. TTFields have been Food and Drug Administration (FDA)-approved for diagnosis and recurrent GBM as additional clinical trial results are revealed. This study reviewed the current status, mechanisms, correlations with immune pathways, the prospects of applying TTFields for GBM, and the adverse events.
