Mechanically-assisted Ventilation in the Treatment of Moving Tumours With Photon and Proton Therapies
Added Value of Mechanically-assisted Ventilation in the Treatment of Moving Tumours (Thoracic/Upper Abdomen) With Photon and Proton Therapies.

Descripción detallada
This will be a three-phase analysis :
First, different ventilation modes will be tested and compared on healthy volunteers. This phase will be analysed with a ventilator and with dynamic MRI in order to measure the movement of anatomical structures in each ventilation mode (intra-fraction analysis). Further, we will repeat these exams in order to compare them with the first ones, in order to analyse the reproducibility and baseline shifts (inter-fraction analysis).
Here are the different ventilation modes
- spontaneous breathing
- physiologic ventilation mode :
- shallow ventilation mode
- slow ventilation mode
- Jet Ventilation mode
Second phase will be done with patients that are intended to have a radiation treatment for thoracic or upper abdominal tumors. All the previous ventilation modes will be analysed during repeated MRI, again in order to perform intra- and inter-fraction analysis of the tumor motion.
Third phase also concerned patients intended to have a radiation treatment. It will be an in-silico-planning analysis in order to quantify dosimetric outcomes of these ventilation modes.

Intervención / Tratamiento |
|---|---|

Experimental: Healthy volunteers on ventilation
Dynamic MRI acquisition will be performed at two different time points with 10 healthy volunteers under non-invasive mechanically-assisted ventilation with a respirator.
Different modes will be compared (spontaneous, physiologic, shallow, slow and jet ventilation).
|
Mechanically ventilation will be done through facial masks connected to a respirator.
Volunteers/patients are fully conscious during the ventilation.
Dynamic MRI acquisition are specific dynamic sequences intended to visualise the motion of internal structures (anatomical structures or tumour) under non-invasive mechanically-assisted ventilation

Experimental: Planning with patients on ventilation
Planning 4D-CT will be performed with 10 patients (intended for a radiation treatment of their thoracic or upper abdominal tumours) under non-invasive mechanically-assisted ventilation with a respirator.
Different ventilation modes will be compared (spontaneous, physiologic, shallow, slow and jet ventilation).

Medida Descripción |
Periodo de tiempo |
|---|---|---|
|
Measure in millimeters of the internal motion during non-invasive mechanically assisted ventilation, based on MRI images
Periodo de tiempo: within 12 months
|
This analysis will be based on dynamic MRI analysis made with healthy volunteers and also patients on non-invasive mechanically assisted ventilation.
A well defined anatomical structure will be selected for the healthy volunteers while the tumor will be tracked in patients.

Tolerance assessment
Periodo de tiempo: within 12 months
|
During all these acquisitions, the tolerance to the non-invasive mechanically assisted ventilation will be assessed by all the participants through a 5-steps scale.
|
within 12 months
|
|
Internal motion reproducibility with non-invasive mechanically assisted ventilation.
Periodo de tiempo: Within 12 months
|
This analysis will be done by comparing the motion of the internal structures/tumors at two different time points (MRI acquisition at two different time points).
All these acquisitions will obviously be done in the same conditions on non-invasive mechanically assisted ventilation.
Motion reproducibility will be analysed by comparing the baseline positions of anatomical structures/tumors on MRI images and the measures in millimeters of motion of the same anatomical structures/tumors.

|
Dosimetric comparison
Periodo de tiempo: within 12 months
|
This dosimetric comparison will be done in order to assess the impact of non-invasive mechanically-assisted ventilation on dose planning and delivery.
Difference in dose (in Gy) to organ at risks will specially be compared through the DVH (dose-volume histogram) analysis.
