Trial summary

Mechanical ventilation can be used to impose a completely regular pattern of breathing frequency and inflation volume on the patient for as long as required. This would considerably improve the reproducibility of the internal motion parameters, and thus facilitate the implementation of respiratory-synchronized… Read more about this study

About this study

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

Mechanical ventilation can be used to impose a completely regular pattern of breathing frequency and inflation volume on the patient for as long as required. This would considerably improve the reproducibility of the internal motion parameters, and thus facilitate the implementation of respiratory-synchronized techniques such as gating, tracking and four-digital optimization.

Read the detailed description

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Non-invasive mechanically-assisted ventilationDiagnostic test

    Mechanically ventilation will be done through facial masks connected to a respirator. Volunteers/patients are fully conscious during the ventilation.

  • Dynamic MRI acquisitionDiagnostic test

    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

  • Planning 4D-CTDiagnostic test

    In order to perform in-silico planning, 4D-CT will be acquired on patients under non-invasive mechanically-assisted ventilation

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Measure in millimeters of the internal motion during non-invasive mechanically assisted ventilation, based on MRI images

    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.

    Measured: within 12 months

Secondary outcomes (3)
  1. Tolerance assessment

    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.

    Measured: within 12 months

  2. Internal motion reproducibility with non-invasive mechanically assisted ventilation.

    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.

    Measured: Within 12 months

  3. Dosimetric comparison

    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.

    Measured: within 12 months

Questions about this trial

What is this clinical trial studying?

A study testing Non-invasive mechanically-assisted ventilation, Dynamic MRI acquisition and Planning 4D-CT in people with Thoracic Neoplasm and Liver Cancer, run by Cliniques universitaires Saint-Luc- Université Catholique de Louvain at 1 site in Belgium.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 Jul 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Belgium. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Measure in millimeters of the internal motion during non-invasive mechanically assisted ventilation, based on MRI images (time frame: within 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Jul 2019.
