Department mission

Since August 2018, patients are treated by proton therapy in Caen, via the Centre François Baclesse radiotherapy department, on the Cyclhad – Normandy Proton Therapy Centre site.

Treatment by proton therapy proposed by the Centre François Baclesse is a national healthcare offer. This is the third site in France to propose this therapeutic modality, after the sites in Orsay (Ile-de-France) and Nice. Given the rarity of this type of equipment throughout France, the Centre François Baclesse proposes this therapeutic option in coordination with other centres, for patients from across France and from abroad.

Conventional radiotherapy uses photon beams (X-rays). Proton therapy uses proton beams. The difference between proton therapy and conventional radiotherapy lies in the manner in which the energy from the employed beam is delivered. In the case of proton beams, the dose can be delivered to the tumour without irradiating beyond this zone.

Healthcare offer and expertise

Adult cancers

For adults, proton therapy is currently indicated in tumours for which balistic and radiological constraints are important. A few indications are currently validated via consensus by the French health authorities.

Treated cancers:

  • Malignant tumours of the cartilage: chondrosarcoma, chordoma
  • ENT cancers
  • Tumours close to the spine, chest or abdominal tumours
  • Tumours of the eye and the orbit
  • Re-irradiation with curative intent
  • Minimally agressive brain tumours (meningioma, paraganglioma – also referred to as chemodectoma, neurinoma – also referred to as schwannoma, craniopharyngioma)

Paediatric cancers

Thanks to its balistic qualities, proton therapy exposes children to a far more reliable dose around the tumour than standard radiotherapy using photons. Its main benefits are reduced local toxicity, both acute and delayed, and reduced functional sequelae (auditive, endocrinian, cognitive), together with a lower very long-term carcinogenic risk.

Treated cancers:

  • Brain tumours
    • Medulloblastoma and other PNETs (Primitive Neuro Ectodermic Tumours)
    • Glioma
    • Ependymoma
  • Tumours of the base of the skull: chraniopharyngioma
  • Soft tissue tumours: rhabdomyosarcoma (RMS), mesenchymal sarcoma
  • Tumours of the nervous system: neuroblastoma
  • Other paediatric tumours

The department’s equipment and facilities

On the Cyclhad site:

  • Access to 1 proton therapy machine – Proteus One® – IBA SA (2018)

The Centre François Baclesse uses Proteus One (IBA) proton therapy equipment, which includes a mobile treatment system (gantry) with pencil beam scanning (PBS), enabling conformational treatment with 3D-modulation of delivered dose.

Results

Activity data 2019

  • Number of external radiotherapy sessions: 2,373
