In the corridors of the onco-radiotherapy department there is the smell of orange trees. A tip from aromatherapists at the Departmental Hospital Center to relax cancer patients.
This also benefits the team of scientists led by Sylvain Crespin, doctor in medical physics, who are busy configuring the brand new linear particle accelerator at €3.8 million. A machine which will be able, from October, to perform extra-cranial stereotaxies.
The technique makes it possible to deliver a larger dose of X-rays with very high precision.

Unlike intracranial stereotaxy, which focuses on small brain lesions, “extracranial stereotaxy allows other organs of the body to be affected,” specifies Cédric Alanet, health executive.
1,900 patients per year
Another advantage, “the new machine takes the respiratory cycle into account”, insists Doctor Deniaud-Alexandre. Enough to gain precision in targeting tumors and other metastases. With a gain in the preservation of healthy tissues. And an increase in the chances of curing certain cancers.

With the tool, the number of X-ray sessions should increase from three to five, compared to ten to 35 for conventional treatment. Good news for the 1,900 patients who pass through the department’s only radiotherapy center each year.
60% of them come to treat breast or prostate cancer. The service, open from 8 a.m. to 8:30 p.m., Monday to Friday, “allows patients to come and have their radiotherapy before or after work. »
+ 3 to 5% per year
To welcome them, seven hospital practitioners and 58 paramedics, including 32 medical electro-radiology technicians. The four bunkered particle accelerators provide nearly 38,000 sessions per year.

These acts increase by 3 to 5% per year. Because of the increase in population. But also thanks to the reputation of the service. To the point of rivaling the hospitals of Nantes, Niort or La Rochelle.

Everything is done to receive the patient in the best conditions. Like the diffusion in the corridors and waiting rooms of essential oils with soothing properties. Or the playing of music on demand in bunkers with ceilings customized with luminous skies and other heavenly landscapes.
In addition to aromatherapy, “manipulators have been trained in sophrology and naturopathy,” explains Cédric Alanet, health executive. “Here, we take care of the patient… not just the tumor. »
The service has used artificial intelligence since November 2019 to delineate the contours of tumors to target. Before calculating the dose of X-rays to distribute. ©Nicolas PIPELIER
