Contact Brachytherapy is a treatment modality where radioactive sources are placed near a tumour. Compared to
external beam radiation therapy, brachytherapy delivers high doses directly to the tissue with rapid dose fall off, reducing
radiation exposure to healthy tissues. Traditional radionucleotide brachytherapy deals in high energies, resulting in
toxicity, the need for suitable shielding and problems associated with the handling of radioactive isotopes.
The Papillon+™ Brachytherapy system replaces radioactive sources with low energy 30 or 50 kVp X-rays. As a result, the
Papillon+™ system combines the advantages of targeted treatment volumes and a high dose rate but without the
accompanying need for significant shielding and a reduction in toxicity. Resulting in dramatically reduced treatment times
and increased patient comfort.
Radiotherapy for surgically exposed tissues using X-ray brachytherapy.
X-ray brachytherapy can offer a simple and effective method of delivering radiation to any surgically exposed site. We currently offer an intra-operative (IO) treatment application for Breast cancer radiotherapy. Future Ariane developments will look to offer a mechanism for delivering our radiation for local surgical ‘boost’ treatments for additional cancer sites by a similar method to IO breast.
In collaboration with our clinical partners at Centre Antoine-Lacassagne in Nice, France. We have developed the ‘Nice’ Breast Applicator for the IO breast application of the Papillon+ device.
The Papillon+ and associated ‘Nice’ applicator allows treatment of surgically exposed breast tissue by x-ray brachytherapy. The applicator allows delivery of an isotropic radiation beam which can reproduce Ir-192 and TARGIT trial depth dose characteristics. This ensures homogenous irradiation of the excised cavity wall.
X-ray brachytherapy for accessible internal tumour sites
X-ray contact brachytherapy is suitable for treatments where x-rays can be placed in contact with a tumour. Therefore it is possible to treat cancers within the natural cavities of the Human body. Our Micronode™ is small enough to allow access to Oral, Vaginal and Rectal cavities.
We currently produce rectal applicators for treatment of lower bowel cancer by the well established ‘Papillon’ technique. Future Ariane Developments will focus on the development of Intra-vaginal applications.
The treatment site is defined via the insertion of an appropriately sized applicator into the rectum, this is then followed by the Micronode™ which emits the radiation to a tumour site. ‘Papillon’ treatment can be delivered in an outpatient setting, with minimal discomfort and recovery times for the patient. Clinically, the Papillon technique can be used in the absence of radical surgery, in situations where a patient is too infirm or has declined surgical intervention.
X-ray brachytherapy applications for the treatment of Skin cancers.
The manoeuvrability and treatment arm of our Papillon+ system allows positioning of the Micronode™ at any position on the patient for irradiation. We can, therefore, facilitate radiation delivery at any exposed tumour site.
We currently provide a suite for the treatment of non-melanoma (basal and squamous cell carcinoma) by electronic contact x-ray brachytherapy.
The use of contact x-ray brachytherapy for the treatment of non-melanoma skin cancers has been shown to produce excellent cosmetic results, along with good control of local disease.
We produce applicators from 20 – 40mm diameter. Our primary collimation system also offers a quick and simple system method for the treatment of smaller tumours, or those of irregular shape – to minimize side effects on healthy tissues.
Combined with our truly portable x-ray generator and workstation, the Papillon+ provides an x-ray brachytherapy solution ideal for skin clinics and outpatient procedures.
