Impact of Non-magnetic Screen Respiratory Self-guidance During MRI-guided Radiotherapy Sessions for Mobile Lesions

The patients eligible for the study are those treated by radiotherapy on Linac MRI for a mobile cancerous lesion (pancreas, liver, kidneys, adrenals, lung, adenopathy above or below the diaphragm ...).

After signing the consent form, each patient will be randomized to one of two treatment arms:

* Standard arm : Radiotherapy treatment with Linac MRI without non-magnetic shielding * Experimental arm : radiotherapy treatment with Linac MRI with non-magnetic screen The aim is to evaluate the effect of using a non-magnetic screen visible to the patient in the bunker during radiotherapy sessions delivered by Linac MRI on decreasing the ratio between the actual treatment time and the treatment time predicted by the machine.

Key information

About this study

The patients eligible for the study are those treated by radiotherapy on Linac MRI for a mobile cancerous lesion (pancreas, liver, kidneys, adrenals, lung, adenopathy above or below the diaphragm ...).

After signing the consent form, each patient will be randomized to one of two treatment arms:

  • Standard arm : Radiotherapy treatment with Linac MRI without non-magnetic shielding
  • Experimental arm : radiotherapy treatment with Linac MRI with non-magnetic screen

The aim is to compare the effect of the non-magnetic screen on the blocking of the patient's breathing versus the current procedure (the blocking of the breathing is informed by the staff)

The patients will each receive 5 sessions of radiotherapy on Linac MRI. 100 patients are expected to participate in this study

Before each session will be assessed for anxiety and stress. After each session will be evaluated patient satisfaction, pain intensity and respiratory effort.

The duration of the treatment and therefore of the follow-up of the patient in the study is 1 to 2 weeks

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Patient is at least 18 years old
  • Patient starting radiotherapy on Linac MRI for a mobile cancerous lesion most often in the pancreas, liver, kidneys, adrenals, lung, supra or subdiaphragmatic adenopathy
  • Patient affiliated to the social security system

Exclusion criteria

  • Patient with lesions not detected by the device's tracking system
  • Patient with visual disturbances
  • Contraindications to treatment with Linac MRI (epileptic patients, pregnant or breastfeeding women, metallic prosthesis or pacemaker not compatible with MRI)
  • Patients with cognitive disorders
  • Persons deprived of liberty or under guardianship (including curatorship)
  • Pregnant or nursing woman
  • Refusal to participate in the study

Treatment and study plan

With non-magnetic screen

Combination Product

Radiotherapy treatment with Linac MRI is performed with a non-magnetic screen that will guide the patient to block the breathing

Primary outcomes

  1. The effect of the non-magnetic screen during radiotherapy (Change in ratio of actual treatment time to the treatment time predicted by the machine).

    Time frame: During 25 months

    To evaluate the effect of a non-magnetic screen visible to the patient in the bunker during radiation therapy sessions delivered by Linac MRI on decreasing the ratio of actual treatment time to the treatment time predicted by the machine.

Secondary outcomes

  1. Patient respiratory effort with visual analog scale

    Time frame: During 25 months

    Patient respiratory effort for each radiotherapy session according to randomization arm.

    The scale is graduated from 0 to 10 with 10 = maximum respiratory discomfort and 0 = no respiratory discomfort

  2. The positional pain with visual analog scale

    Time frame: During 25 months

    Compare the positional pain associated with setting up on the treatment table for each radiation therapy session according to the randomization arm.

    The scale is graduated from 0 to 10 with 0 = absence of pain and 10 = maximum pain

  3. Level of anxiety/stress evaluated with the Spielberg scale via the STAI-Y-form grid

    Time frame: During 25 months

    To assess the average level of anxiety/stress for each radiation therapy session according to the randomization arm. The Spielberg scale via the STAI-form Y-A grid is used before each treatment session in order to follow the evolution of the patients' emotional state.

    20 questions with 4 possible answers : 1/ Not at all, 2/ A little, 3/Moderately , 4/ A lot.

  4. The potential time

    Time frame: During 25 months

    Evaluate whether the potential time savings in screen time compensates for the time spent learning the screen during the simulation.

  5. The patient satisfaction evaluated with an ad-hoc questionnaire.

    Time frame: During 25 months

    The patient's satisfaction with his or her involvement in the treatment process will be evaluated at the end of the 5 radiotherapy sessions using an ad-hoc questionnaire.
