About this study

Official title: Study of the Interest of the Parametric Imaging in Positron Emission Tomography on the Recurrence Prognosis at One Year in Patient With Non Small Cell Lung Cancer

The purpose of this study is to evaluate the concordance between Positron E mission tomography parametric imaging versus standard PET for the 1 year prognosis of patients with NSCLC treated by radiochemotherapy.

The ancillary study will evaluate the interest of parametric PET imaging during the treatment (around 42 Gray) to detect the local relapse of the lesion in order to propose a treatment re-planification or intensification (not realized on the present study).

Read the detailed description

In oncology, Positron Emission Tomography imaging with 18Fluor-FDG quantifies glucose metabolism lesions. Conventionally, the metabolism is quantified using the Standard Uptake Value (SUV) from a static acquisition obtained 60 minutes post-injection. Some teams reported SUV variation coefficients as high as 30% in NSCLC lesions for repeated PET examinations in patients without treatment. Moreover, information regarding the binding kinetics of 18Fluor-FDG by tumor cells is not accessible through this method.

Much more elaborated FDG quantification methods and considered as reference methods exist in PET imaging (compartmental analysis, Patlak). Simplified kinetic methods have also been proposed which correlate better with Patlak reference method than the conventional SUV. The investigators proposed a new methodological approach to obtain the parametric information in PET. This approach allows to define new indexes (average percentage of FDG-metabolized or not metabolized; time required to metabolize 80% of FDG). The approach has been clinically evaluated in a pilot study for the differentiation between benign and paraganglioma lesions.

Tsuchida observed that the parametric PET imaging allowed histological differentiation of subtypes of lung tumors, reflecting the difference in glucose transporters and hexokinase between adenocarcinoma and squamous cell carcinoma. Xue et al showed that the FDG uptake (based on the only SUV) could be a tool to predict the subtype and thus tumor staging in patients suffering from NSCLC.

The investigators can then hypothesize that some subtype of lung tumor, with increased proliferation rate (kinetic indexes k3, Ki or other parameters offered by our previous work), will be more sensitive to radiotherapy and thus the evaluation of tumor subtype by PET would allows radiotherapy adaption accordingly.

This study is a preliminary methodological study , strictly descriptive and will only assess the comparison of measurements obtained on a parametric imaging and imaging "static" in patients suffering from NSCLC . The measures of the uptake and volumes estimated by two approaches will be correlated and compared with the 1 year clinical outcome (primary objective).

An ancillary study will assess the relevance of the approach to detect, at the tumor level , an early recurrence of the disease. For this, the images acquired during the radiotherapy treatment (at 42Gy) will be analyzed retrospectively and the correlation with the images to 3 months or 1 year of relapsing patients will be analyzed.

Questions about this trial

What is this clinical trial studying?

A study testing Parametric Imaging in people with Non Small Cell Lung Cancer, run by Centre Henri Becquerel at 2 sites 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 7 inclusion and 9 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 2 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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?

Prognosis of recurrence (time frame: one year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02821936, which also lists 1 linked publication.

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 2 Jan 2026; AzTrials last refreshed its copy on 6 Nov 2026.
