Professionals at your service
Your first contacts in the department will be the medical assistant, who will take your appointments, and the manipulator coordinator, who will organize your treatment and act as an intermediary with the team.
You will then meet the radiotherapist in charge of your treatment, and the manipulators who will take charge of your preparation and treatment sessions. The department is staffed by a multidisciplinary team who work closely together to do their utmost to welcome you, care for you, help you and answer your questions.
The Centre François Baclesse also offers a range of supportive care services that may be required alongside specific treatments (nutrition, pain management, psychology, etc.).

Service mission
Since August 2018 patients have been treated in Caen for their proton therapy treatment by the Radiotherapy department of the Centre François Baclesse at the Cyclhad site of the Normandy Proton Therapy Center.
Proton therapy treatment at the Centre François Baclesse is a treatment option with a national dimension. It is the third site in France to offer this therapeutic modality, after the Orsay (Ile-de-France) and Nice centers. Given the scarcity of this type of facility in France, the Centre François Baclesse offers this therapeutic option, in coordination with other centers, to the French population.

Benefits of proton therapy
Proton therapy is an innovative technique for limiting the toxicity and improving the efficacy of certain photon-based radiotherapy treatments.
Conventional radiotherapy uses photon beams (X-rays). Proton therapy uses proton beams. The difference between proton therapy and conventional radiotherapy lies in the beam energy deposition method used. The deposition of proton beam energy enables the tumor to be treated without irradiating beyond this zone.


During radiotherapy treatment, healthy tissues in the vicinity of the tumor (critical organs) are bound to receive a certain dose, potentially generating side effects.
The physical properties of protons enable them to deliver their dose to the tumor without irradiating beyond it. As a result, proton therapy significantly reduces the dose of radiation to healthy tissues, with a consequent reduction in toxicity compared with the particles used in conventional radiotherapy.
Proton therapy can reduce both short- and long-term side effects. In particular, it reduces the likelihood of secondary tumors developing in patients treated during childhood and adolescence.
Proton therapy is used to treat cancer in patients for whom precise irradiation is even more critical than for conventional radiotherapy. This is the case for children with cancer, or adults with cancer located near critical, radiation-sensitive organs. Proton therapy is also indicated when conventional methods become too toxic and/or ineffective.
However, it is not suitable in all cases. Your treatment team will suggest the best radiotherapy technique for your individual case.
Care and Expertise
Adult cancers
For adults, proton therapy is currently indicated for tumors with high ballistic and radiobiological constraints. Some indications are currently consensual and validated by the French health authorities.
Radiation-resistant tumors are also indications for proton therapy, as they require high radiation doses to ensure tumor control, especially if they are close to organs with limited tolerance.
Indications are discussed on a case-by-case basis, based on a complete medical file and comparative dosimetry. The decision is validated by a specialized Multidisciplinary Consultation Meeting (RCP).
Cancers treated :
- Malignant cartilage tumors: chondrosarcomas, chordomas
- ENT tumors
- Tumors close to the spine, thoracic or abdominal tumors, not very mobile
- Tumors of the eye and orbit
- Curative re-irradiation
- Less aggressive brain tumors (meningiomas, paragangliomas also known as chemodectomas, neurinomas also known as schwannomas, craniopharyngiomas)...
Childhood cancers
Thanks to its ballistic qualities, proton therapy exposes children to a much lower dose around the tumor than conventional photon radiotherapy. Its main advantages are the reduction of local, acute and late toxicities, functional sequelae (auditory, endocrine, cognitive) and very long-term carcinogenic risks.
Cancers treated :
- Brain tumors :
- Medulloblastoma and other PNETs (Primitive Neuro Ectodermic Tumors),
- Gliomas
- Ependymomas
- Skull base tumor: Craniopharyngioma
- Soft tissue tumors: rhabdomyosarcomas (RMS), mesenchymal sarcomas
- Nervous system tumor: neuroblastoma
- Other pediatric tumors
Clinical research
Proton therapy is an innovative technique that generates less toxicity and is more effective than some "conventional" photon radiotherapy treatments.
However, given the cost of proton therapy and the steady progress of conventional radiotherapy treatments, the indications for this new technique need to be justified and prioritized.
In this constantly evolving technological landscape, prospective work to analyze and demonstrate the advantages of proton therapy over photon therapy must therefore be carried out on an ongoing basis, in medical, societal and financial terms.
All patients treated with proton therapy are offered the opportunity to record their treatment and follow-up data in a secure database, shared with their referring radiotherapist.
Patients are also frequently invited to take part in a clinical research study as part of their proton therapy treatment, particularly for indications where the level of evidence needs to be strengthened.
Service equipment
On the Cyclhad website:
- Access to 1 Proteus One® proton therapy machine - IBA SA (2018)
The Centre François Baclesse uses Proteus One proton therapy equipment (IBA) featuring a gantry system with pencilbeam scanning (PBS), enabling conformal treatment with 3D modulation of the delivered dose.

Practical information
Hosting
Proton therapy treatment sessions take place on a daily basis over several weeks. Most patients are not hospitalized during this period. This means that patients who are geographically distant must find suitable accommodation. We can help you find suitable accommodation.
Most patients are not hospitalized during this period. Patients who are geographically distant must therefore find accommodation: we can help you in your search.
Accommodation is at your own expense. However, if you belong to a mutual insurance company, you may be able to apply for reimbursement of accommodation costs. Ask your health insurance company for details.
Accommodation is located in Caen or on the coast, a 20-minute drive away.
Depending on your needs, we can refer you to a standard hotel, service residence or apartment hotel.
The Centre François Baclesse has agreements with accommodation providers giving access to preferential rates for Centre patients:
- DOMYTIS
Temporary accommodation in Caen, Cabourg, Dives-sur-Mer, Bayeux, Courseulles-sur-Mer

Foreign patients
Proton therapy is also available to patients from all over the world. These patients, who are not affiliated to the French social security system, can send a request for treatment to the Centre François Baclesse, either themselves or via their doctor.
Financial coverage of medical expenses for foreign patients
Before drawing up an estimate for treatment at the Centre François Baclesse, a complete medical file (detailed below) is required so that our radiotherapy medical team can validate the choice of treatment.
If a treatment is recommended in our establishment, an estimate will be proposed to you.
If you validate this estimate, you will be asked to pay it in full before the treatment begins.
Additional costs will be incurred: transport, accommodation, meals, etc.
