Tumor Treating Fields (TTFields) is a cancer therapy that uses electric fields tuned to specific frequencies to disrupt cell division, inhibiting tumor growth and causing affected cancer cells to die. [Science of TTFields]. TTFields are delivered to the body region where the tumor is located using an investigational medical device, called the NovoTTF-100L(P) System. The system is a portable, light-weight, battery operated device designed to deliver TTFields to the region of the liver cancer. Patients receiving TTFields need to wear four transducer arrays on their abdomen, back and flanks, which deliver the fields non-invasively to the abdomen. The system is intended for continuous home use by patients [Living with TTFields].
TTFields tuned to a different frequency (200 kHz) has been approved by the FDA and EU for treatment of adult patients suffering from recurrent and newly diagnosed glioblastoma.
