About this study

Official title: Assessment of Four-dimensional (4D) 18F-fluoro-deoxy-glucose (FDG) Positron Emission Tomography and Computed Tomography System (PET-CT) in Radiotherapy for Non Small Cell Lung Cancers (NSCLC)

Computed tomography (CT) images, used for radiotherapy planning, are often caught out in lung target volumes delineation because of their inability to differentiate between neoplasia, inflammation and atelectasia. Positron Emission Tomography (PET) is a new functional imaging modality and is currently used in the diagnosis and the staging of lung cancers. The aim of this study is to evaluate the impact of 4D 18F-FDG-PET-CT on radiotherapy planning for lung cancers.

Read the detailed description

Many PET studies have been interested in lung radiotherapy volumes definition, however lacking any standardisation. Effectively, the use of PET images is difficult because of the poor image quality resulting from noise and partial volume effects induced blurring. Moreover, due to the long duration of PET acquisitions, respiratory motions are inevitable and result in artifacts in the PET images affecting the volumes and contrast of the tumour: tumours may appear larger while their activity can be lower. To overcome these limitations, we propose to use a 4D PET-CT, ie a PET-CT acquisition system synchronized with respiration in order to compare CT-simulation target volumes and PET target volumes after application of different approaches for partial volume effect correction, respiratory motion correction and automatic segmentation method of functional volumes. For this purpose, patients with a non small cell lung cancer and having to be treated with radiotherapy or radio-chemotherapy underwent CT-simulation and 4D PET-CT in radiotherapy treatment position. The target volumes and the dosimetries obtained with both modalities were compared.

What is being measured

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

  1. Quantitative and qualitative differences between CT-simulation and 4D PET-CT volumes

    Quantitative and qualitative differences between the radiotherapy target volumes obtained from CT-simulation and from 4D-PET-CT.

    The quantitative difference is expressed as a percentage of the total volume defined on CT simulation.

    The qualitative difference is defined as the volumes defined only on CT-simulation or only on 4D-PET-CT, expressed as a percentage of the total volume defined on CT-simulation.

    Measured: between day 7 and day 21 after inclusion

Secondary outcomes (2)
  1. Dosimetrics differences between the dosimetries obtained from CT-simulation or from 4D-PET-CT.

    Measured: between day 7 and day 21 after inclusion

  2. Search of predictive criteria (histology, tumour localization, TNM staging) for 4D-PET-CT impact on the radiotherapy target volumes and on the dosimetries.

    Measured: between day 7 and day 21 after inclusion

Questions about this trial

What is this clinical trial studying?

A study testing CT-simulation and 4D PET-CT in people with Lung Cancer and Non-small-cell Lung Carcinoma, run by University Hospital, Bordeaux at 1 site in France.

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 4 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 29 May 2026. 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 France. 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?

Quantitative and qualitative differences between CT-simulation and 4D PET-CT volumes (time frame: between day 7 and day 21 after inclusion). 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 29 May 2026.
