Proton therapy for prostate cancer
A non-invasive treatment that preserves urinary, erectile and bowel function
Proton therapy is the external radiotherapy option with the lowest toxicity for prostate cancer. By concentrating the dose on the tumour, it minimises exposure to the bladder and rectum, reducing the risk of incontinence and impotence. It is an outpatient treatment that is painless and non-invasive, and its lower toxicity allows for a higher radiation dose and fewer treatment sessions.
The Proton Therapy Unit at the Cancer Centre of the Clinica Universidad de Navarra, with facilities in Madrid, works in close collaboration with the Prostate Cancer Unit, the first centre in Spain to offer the full range of diagnostic and therapeutic options for the management of this disease.

Indications for proton therapy in prostate cancer
- Advanced-stage localised prostate cancer (high-risk): in these cases, radiotherapy is the first-line treatment.
- Localised prostate cancer (intermediate- or low-risk): radiotherapy is a curative option recommended for localised prostate tumours.
- Spread and/or more aggressive tumours: radiotherapy is indicated in combination with hormone therapy.
- Recurrent prostate tumours: in these cases, proton therapy is a treatment option for tumours previously treated with other forms of radiotherapy.
- Hypofractionated proton therapy (5–10 sessions) is being explored as a cost-effective alternative.
Why at the Clínica Universidad de Navarra
The prostate cancer treatment programme at the Cancer Centre of the Clinica Universidad de Navarra features Spain’s first Prostate Centre, which forms part of the Cancer Centre.

Reference Center
The Clínica Universidad de Navarra is an international reference center in the diagnosis and treatment of cancer, offering patients and their families access to an interdisciplinary approach to esophageal cancer.

A unique concept
First facility in Spain integrated in an Intrahospital Cancer Center, with all its assistance, academic and research support.

Advanced technology
As a highly complex center, we have the most advanced technology for the most accurate diagnosis in the shortest time possible.
The most precise radiation therapy for cancer
The Proton Therapy Unit’s technology allows the beam energy to be adjusted layer by layer, enabling the tumour to be targeted with maximum precision whilst ensuring the dose is precisely tailored, and allowing the exact position of the tumour to be verified daily before each session — a particularly important consideration in prostate cancer, where the proximity of the bladder and rectum requires the utmost precision to spare these organs.
