Quironsalud Proton Therapy Center

As one of Europe’s largest and most advanced hospital groups, Quironsalud continues to set new standards in medical innovation. In late 2019, the Quironsalud Group launched the Quironsalud Proton Therapy Center, a groundbreaking project designed to bring world-class cancer treatment to Spain.

A State-of-the-Art Center Equipped With the Latest Technology

The center is the first of its kind in the country, featuring some of the most advanced technologies in modern radiation oncology, including:

Proteus One® proton irradiation system

High-definition CT scanning

Surface-guided radiation therapy systems

Monte-Carlo dose calculation algorithms

The infrastructure was created with patient comfort in mind. The facility includes:

5 waiting rooms

2 consultation suites

2 post-anesthetic recovery rooms

The center’s mission is to serve as a hub for technological excellence, continuously improving proton therapy techniques to benefit patients long-term.

Expert Oncology Team

The medical team includes highly respected radiation oncologists, each with more than 20 years of experience, such as:

Dr. Raymond Mirabell

Dr. Karme Ares

Dr. Juan Castro

About Proton Therapy

Proton therapy is an innovative form of radiation treatment introduced in Spain for the first time by Quironsalud. It is particularly effective for tumors in sensitive areas such as the eye, brain, spine, and pediatric cancers.

Key Benefits of Proton Therapy

The center uses the Proteus One® system, considered one of the most advanced technologies available today.

What Sets Proteus One® Apart?

High level of safety

220° rotational capability around the patient

Ability to deliver radiation from multiple angles with pinpoint accuracy

Supports future advancements like FLASH therapy and rotational proton therapy

Another essential element is the synchrocyclotron, which adjusts proton speeds precisely according to each patient’s treatment needs.

How Proton Therapy Works

High-energy protons are directed at the tumor site.

They release their maximum energy directly inside the tumor, sparing surrounding healthy tissues.

Protons stop precisely at the tumor, reducing accidental radiation exposure.

This significantly lowers the risk of long-term side effects and secondary tumors.

Cancers Treated With Proton Therapy

According to the Spanish Society of Radiation Oncology, over 1,000 patients in Spain qualify for proton therapy every year. Conditions that can be treated include:

Pediatric cancers

Spine tumors

Lung cancer

Head & neck sarcoma

Skull base tumors

Breast cancer

Ocular tumors

Why Proton Therapy Is Gaining Global Recognition

Proton therapy is considered one of the safest and most advanced forms of radiation treatment due to:

Adjustable, highly controlled radiation dosing

Exceptional accuracy

Minimal impact on surrounding tissues

Low risk of secondary tumors

These advantages improve treatment safety and overall quality of life for patients.

Patient Journey at Quironsalud Proton Therapy Center

Preliminary Evaluation
An interdisciplinary team (radiation oncologists, pediatric specialists, etc.) reviews all medical reports to confirm eligibility.

Personalized Treatment Plan
A fully customized therapy plan is created for each patient.

Initial Consultation
Doctors explain the entire process and answer all questions.

Diagnostic Imaging
The patient undergoes an HD CT scan for precise treatment planning.

Custom Immobilization Mask
Each patient receives a mask tailored to maintain correct positioning during sessions.

Ambient Experience Setup
Using Philips Ambient® technology, patients select calming visual themes to enhance comfort.

Treatment Session
The patient remains still while the Proteus One® system rotates up to 220° to deliver targeted proton beams.
Radiation delivery lasts only a few minutes.

Proton Therapy Success Rates

While success rates are similar to other advanced radiation therapies, proton therapy offers superior safety, especially for sensitive tumor locations.

Cancer Type Success Rate
Prostate Cancer (Stage 1–3) 99%
Breast Cancer (Early stages) 97.2%
Lung Cancer 86.5%
Head & Neck Cancer 66.8%
