Proton Therapy

"Protontherapy is the most precise external radiation therapy that protects healthy tissue as much as possible because it does not expose them unnecessarily to radiation".

Proton therapy is a high-precision radiotherapy technique that concentrates the dose on the tumour whilst minimising radiation exposure to healthy tissue. In 2020, the Cancer Centre at the University of Navarra Clinic launched the first hospital-based proton therapy unit in Spain.

Since then, it has treated more than 1,300 patients from all the autonomous communities and from different countries, with indications for more than twenty types of tumour. 27% of patients are under 18 years of age.

The Proton Therapy Unit at the Cancer Center Clínica Universidad de Navarra incorporates a Hitachi synchrotron (particle accelerator), this technology is present in 32 clinical and academic centres, including international leaders in cancer treatment such as the Mayo Clinic, MD Anderson, Johns Hopkins, St. Jude’s Children’s Research Hospital and Hokkaido University Hospital.

Proton therapy in Madrid

The proton therapy facilities at the Cancer Centre of the Clínica Universidad de Navarra are located in Madrid. Since it opened in April 2020, it has treated more than 1,300 patients from all of Spain’s autonomous communities, with treatments for more than 20 types of tumour. Almost one in three patients —27%— are under the age of 18.

An international reference center for fighting cancer

Treating over 8,600 patients per year, the Cancer Center Clínica Universidad de Navarra has accumulated almost 40 years of experience at the forefront of personalized cancer medicine.

A unique 
concept

We are the first facility in Spain integrated within an inpatient cancer center, with extensive patient-care, academic and research support.

Cutting-edge technology

The Hitachi synchrotron, used in international reference hospitals in the diagnosis and treatment of cancer, guarantees minimum irradiation times, great precision in tumor inactivation and the highest levels of safety and comfort for patients.

Professional 
experts

Our professionals are internationally renowned in cancer treatment, with extensive proton therapy training, and they have produced impressive scientific output in clinical and translational radiotherapy innovation.

La Clínica Universidad de Navarra se encuentra, según la revista Newsweek, entre los 120 mejores hospitales del mundo.

Indications for proton therapy to fight cancer

IN MADRID

Adults

Proton therapy is most effective in treating cancer that is localized, particularly tumors that have not spread to other parts of the body. If the tumor has spread (metastasized), proton therapy may be an option depending on the number of metastases and other factors (oligometastatic or oligorecurrent disease).

Children

Proton therapy is generally the preferred treatment for tumors that can be treated with external radiation therapy by virtue of being the form of treatment that best preserves healthy tissue and reduces adverse effects on growing structures.

Care and research project

Through the acquisition of this technology, the Clínica Universidad de Navarra has established a strategic alliance with Hitachi and joined the clinical and research associations that unite the different centers using this technology.


Facilities

The Proton Therapy Unit has a synchrotron (the proton beam delivery system), two patient treatment rooms with 360-degree gantries, treatment-associated work areas and support facilities.


A “clean” accelerator

This equipment features a synchrotron as a particle accelerator: it is the most up-to-date accelerator, and it is significantly more energy-efficient than the cyclotron, as it produces less unwanted irradiation.


Patient benefits

The dynamic scanning beam, or pencil beam scanning, scans the tumor. This enables enhanced dose–tumor conformity, maximizing the dose deposited in the tumor and minimizing the dose in healthy tissue.
