About this study

Official title: Predictive Study of Radiation Induced Sarcoma From the GSF-GETO Data Base.

Development of sarcoma within or adjacent to radiation field is a well known event of poor prognosis and unknown risk factors. Advanced techniques of radiation therapy including intensity modulated radiation therapy, tomotherapy or Arc therapy are providing new modalities of radiation delivery that could be responsible for developing these induced tumors. There is little data on molecular biology of radiation induced sarcoma even if some tools are still available to characterize these types of tumors aiming to compare their profile to a sarcoma observed in non irradiated area. An update of the GETO-GCSF registry, currently called CONTICANET data base in the framework of EORTC, represents the backbone of the project. The next step should follow two axes, a clinical one based on the dosimetric analysis of the characteristics of delivered radiation therapy and the second one based on a molecular characterization of the sarcomas developed in irradiated field.The data base will be updated and organized through the CONTICANET network and the radiation oncologists involved in the treatment of soft tissue sarcoma. A retrospective analysis of the clinical data and the parameters describing the initial treatment will be registered using the methodology proposed by I. Diallo for radiation induced tumors developed in childhood. The most recent data will be extracted in DICOM format for intercomparison in a dedicated software.A centralized review of pathological specimens is planned to validate the correct classification of the tumors inside the current staging system developed for soft tissue sarcoma.

Read the detailed description

The biological study will include the two following steps:1. On frozen specimen: genic profile of the tumor will be studied with two different techniques: CGH-array from extracted DNA in order to evaluate the number of gene copies, amplifications and deletions. The RNAm expression profile will be studied to evaluate the level of the gene expression. More than 200 data collected in Institut Bergonié, coming from de novo sarcoma would be used as a comparative specimen since the pathological diagnosis is the same as the one observed for radiation induced sarcoma. A comparison between the two populations will be able to define profiles, gene modifications and signalisation pathways of radiation induced sarcoma. 2. On blood sample: 2 groups of patients will be compared: those with radiation induced sarcoma and patients receiving radiation therapy for more than 5 years ago without developing sarcoma. The study will be performed with the inform consent of the patients and of the controlled cases.This second step requires 2 blood samples (2 x 5 ml). They will be collected and sent to the molecular biology laboratory located in Centre Alexis VAUTRIN (Nancy).- One sample of 5 mm will be dedicated to study radiation induced apoptosis assessed by flow cytometry. A correlation has been described between radiation-induced apoptosis of CT8+ lymphocytes after an 8 Gy irradiation and the occurrence of severe late toxicity after radiation therapy for patients treated for several types of tumors.- The second sample will be used to study the polymorphism of the genes involved in reparation of DNA by using chip screening of single nucleotide polymorphisms (SNP). This sample will be used after DNA extraction from mononuclear blood cells. DNA will be extracted and controlled by flow cytometrical separation. It will be sent to Bordeaux molecular biology laboratory in Institut Bergonié (Prof. JM COINDRE) to perform an evaluation of the single nucleotide polymorphism. The aim of this part of the protocol is to study variances in gene, the product of which plays a role in radiation response and in the development of adverse effects after radiation therapy. For patients with radiation-induced sarcoma, the results of this analysis will be compared with the data obtained from DNA analysis extracted from the tumors. The clinical, pathological and biological characterisation of radiation-induced sarcoma obtained will allow to identify constitutional variances linked with an increased sensitivity to radiation therapy leading to discuss indication of irradiation in a population at risk. Pediatric radiation therapy and adjuvant treatment after surgery for breast carcinoma will be the main targets of this selection of patients. This project will be able to select radiation modality in patients at risk (intensity modulated radiation therapy or 3D conformal approach, stereotactic approaches, partial irradiation of the breast).

What participants receive

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

  • tumor genetic predisposition to develop sarcoma assessmentGenetic

    data concerning initial radiation and localisation of the sarcoma secondary developed will be collected. 2 blood samples (2 x 5 ml)will be collected. One sample of 5 mm will be dedicated to study radiation induced apoptosis assessed by flow cytometry. The second sample will be used to study the polymorphism of the genes involved in reparation of DNA by using chip screening of single nucleotide polymorphisms (SNP). DNA will be extracted and controlled by flow cytometrical separation.

What is being measured

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

  1. Determine the predictive clinical and biological risk factors to develop a sarcoma on irradiated territory.

    Clinical data of initial radiation therapy, radiation-induced apoptosis of CT8+ lymphocytes and polymorphism of the genes involved in reparation of DNA by using chip screening of single nucleotide polymorphisms (SNP) will be studied for each patient included.

    Measured: from date of inclusion up to the end of recruiting period : november 2013 (anticipated)

Questions about this trial

What is this clinical trial studying?

A study testing tumor genetic predisposition to develop sarcoma assessment in people with Radiation Induced Sarcoma, run by Centre Georges Francois Leclerc 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 4 inclusion and 6 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 12 Jun 2017. 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?

Determine the predictive clinical and biological risk factors to develop a sarcoma on irradiated territory. (time frame: from date of inclusion up to the end of recruiting period : november 2013 (anticipated)). 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 12 Jun 2017.
