Background Malignant brain tumors are among the most threatening
diseases of the central nervous system, and despite increasingly updated
treatments, the prognosis has not been improved. Tumor treating fields
(TTFields) are an emerging approach in cancer treatment using
intermediate-frequency and low-intensity electric field, and can lead to
development of novel therapeutic options. Recent findings A series of
biological processes induced by TTFields to exert anti-cancer effects
have been identified, and applications of TTFields in oncology have been
increasingly reported. This review addresses the mechanisms of TTFields
and recent advances in the application of TTFields therapy in malignant
brain tumors, especially in glioblastoma (GBM). Conclusions As a novel
therapeutic strategies, TTFields have shown promising results in many
clinical trials, especially in GBM, and continue to evolve. A growing
number of patients with malignant brain tumors are being enrolled in
ongoing clinical studies demonstrating that TTFields-based combination
therapies can improve treatment outcomes.
