Trial summary

Context: Studies that address specifically the neurocognitive consequences that can be caused by low-dose radiation receiving during the childhood have still to be performed. In this issue, we focus on an investigation with patients who have received radiotherapy for a benign tumor (skin hemangioma), in France. Read more about this study

About this study

Official title: Etude Des séquelles Neurocognitives à Long Terme Des Faibles Doses de Radiation Chez 150 Patients traités Par radiothérapie Dans l'Enfance Pour un hémangiome cutané à l'Institut Gustave Roussy (IGR) Entre 1941 et 1973

Patients and methods: More than 8300 children with a skin hemangioma were treated at Gustave Roussy (Île-de-France) from 1941 to 1973 and a number of them have received radiotherapy. These patients have been treated and followed by Gustave Roussy, so their clinical records can be tracked with great accuracy and the ionizing radiation dose to the brain have been estimated. From this patient cohort, the aim is to evaluate neurocognitive dysfunction or disorder that can be caused by low-dose radiation to the brain (less than one Gray (Gy)). A total of 150 patients is expected. They will be contacted by letter to explain the purpose and methods of carrying out tests. Two groups will be analysed according to the received ionizing radiation dose to the brain during the radiotherapy (exposed: 0.05 to 1 Gy, vs unexposed: less than 0.05 Gy). Tests exploring several cognitive functions (memory, arithmetic, orientation, etc.) will be used.

Expected results: We expect to describe the potential neurocognitive dysfunction or disorder and to identify risk factors and brain structures whose lesions are responsible for the neurocognitive dysfunction or disorder.

A therapeutic treatment will be proposed in the eventuality of screening of a neurocognitive dysfunction or disorder.

Read the detailed description

CogRad is an interventional study designed within the European project called Cognitive and Cerebrovascular Effects Induced by Low Dose Ionizing Radiation (CerebRad).

CerebRad is a collaborative European project funded in 2011 within the 7th European Union (EU) framework programme, Nuclear Fission and Radiation Protection. CerebRad aims to identify the potential cognitive and cerebrovascular risks of radiation doses below 100 milliGray (mGy) when delivered to a young child (pre- or postnatally).

Conditions: Patients Treated by Radiotherapy With < One Gy to the Brain
Being tested: neurocognitive tests battery

What participants receive

What is being measured

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

All neurocognitive dysfunction or disorder on adults measured by means of eight tests
The score to the 8 tests will be correlate with the presence of neurocognitive dysfunction or disorder
Measured: Participants will be tested for the duration of hospital stay (half a day).The neurocognitive tests battery will be carry out 56 years on average after exposure to low-dose radiation.

Questions about this trial

What is this clinical trial studying?

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 12 inclusion and 2 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 23 Apr 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?

All neurocognitive dysfunction or disorder on adults measured by means of eight tests (time frame: Participants will be tested for the duration of hospital stay (half a day).The neurocognitive tests battery will be carry out 56 years on average after exposure to low-dose radiation.). 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 NCT01960751, which also lists 9 linked publications.

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 23 Apr 2026; AzTrials last refreshed its copy on 7 Nov 2026.
