Tumor-treating fields (TTFields) are a new technology used for cancer treatment consisting of battery-powered, insulated electromagnetic transducers that are placed on the scalp. This wearable, adhesive device is a certified physician-prescribed therapy for patients with glioblastoma multiforme, a type of primary brain cancer. TTFields are being used concomitantly with temozolomide (Temodar®) in patients with newly diagnosed glioblastoma and as a monotherapy in patients with recurrent glioblastoma after radiation therapy and chemotherapy. Nursing professionals caring for patients using this emerging technology should be able to educate patients regarding proper use of TTFields and monitor for side effects.


  • TTFields are an innovative therapy currently used in the treatment of glioblastoma.
  • Patient education is essential to ensure correct use of the device and maximize efficacy of therapy.
  • Nursing professionals should routinely monitor for side effects associated with TTFields use by performing a focused physical assessment on patients undergoing treatment.
