Optune Gio (TTFields): an innovative therapy for grade 4 glioma

TTfield At the Radiotherapy Unit of HC Cancer Center, we keep advancing in the incorporation of innovative oncological treatments that contribute to improve the survival and quality of life of our patients. One of the latest advances we have incorporated is Optune Gio, a portable and non-invasive medical device based on Tumour Treating Fields (TTFields) technology, indicated for the treatment of grade 4 glioma.
 
 

This technology is a therapeutic alternative that complements conventional treatments, offering another option for patients diagnosed with this type of aggressive brain tumour.
 

How does Optune Gio work?

Optune Gio acts directly on tumour cells by emitting low-intensity electric fields through patches placed on the scalp. These fields interrupt cancer cell’s ability to divide, preventing them from multiplying, without damaging the surrounding healthy tissue.
 
Treatment is continuous and the device can be used at home, thus allowing patients to maintain a relatively normal daily routine, without the need for hospitalisation.

Who is it indicated for?

This device is indicated for adult patients with newly diagnosed grade 4 glioma and can be used in the following scenarios:
 

  • After resection surgery or biopsy of the tumour
  •  

  • After radiotherapy treatment
  •  

  • In combination with Temozolomide (with or without Lomustine) as maintenance treatment
  •  

  • At the end of systemic therapy
  •  

The goal is to slow tumour growth and improve survival after completing the initial phases of treatment.
 

Advantages of treatment with Optune Gio

  • It improves the overall survival of patients.
  •  

  • It prolongs the time patients do not experience tumour progression.
  •  

  • It is non-invasive, painless and does not require hospitalisation.
  •  

  • It is compatible with other treatments such as chemotherapy.
  •  

  • It allows patients to lead an active life and maintain their autonomy.
  •  

  • Low level of adverse effects; the most common is mild skin irritation.
  •  

  • Mejora la supervivencia global de los pacientes.

Scientific support

The efficacy of Optune Gio has been supported by numerous clinical studies. The most relevant of these is the EF-14 trial, in which it was observed that:
 

  • Median overall survival increased from 16 to 20.9 months.
  •  

  • The 5-year survival rate doubled (from 5% to 13%) in patients treated with Optune Gio and Temozolomide.
  •  

  • There was a significant improvement in the quality of life related to overall health and cognitive function of the patients.
  •  

  • La supervivencia media global aumentó de 16 a 20,9 meses.
  •  

This treatment is recommended by international guidelines such as those of the National Comprehensive Cancer Network (NCCN) and is CE marked (CE-0197) for use in Europe.
