Tumour‑treating fields (TTFields) therapy improves overall survival in patients with newly diagnosed and recurrent glioblastoma multiforme

Glioblastoma multiforme (GBM) is the most common primary brain tumour in adults and continues to portend poor survival, despite multimodal treatment using surgery and chemoradiotherapy. The addition of tumour‑treating fields (TTFields) – an approach in which alternating electrical fields exert biophysical force on charged and polarisable molecules known as dipoles – to standard therapy, has been shown to extend survival for patients with newly diagnosed GBM, recurrent GBM and mesothelioma, leading to the clinical approval of this approach by the FDA. TTFields represent a non‑invasive anticancer modality consisting of low‑intensity (1–3 V/cm), intermediate‑frequency (100–300 kHz), alternating electric fields delivered via cutaneous transducer arrays configured to provide optimal tumour‑site coverage. Although TTFields were initially demonstrated to inhibit cancer cell proliferation by interfering with mitotic apparatus, it is becoming increasingly clear that TTFields show a broad mechanism of action by disrupting a multitude of biological processes, including DNA repair, cell permeability and immunological responses, to elicit therapeutic effects. This review describes advances in our current understanding of the mechanisms by which TTFields mediate anticancer effects. Additionally, we summarise the landscape of TTFields clinical trials across various cancers and consider how emerging preclinical data might inform future clinical applications for TTFields.

GBM remains one of the most lethal primary brain tumours with median overall survival of 10–16 months despite standard chemoradiotherapy. TTFields provide a non‑invasive therapeutic option that has been clinically approved and shown to extend survival, offering a potentially improved treatment avenue for patients with limited options.
