Trial summary

At present, the only recognised prognostic factor for primary high-grade osteosarcoma is the histological response to preoperative chemotherapy. Our study was designed to identify new diagnostic markers that could eventually have a prognostic value and therapeutic consequences. Read more about this study

About this study

Official title: Study of Prognostic Value by Molecular Analysis in Paediatric Osteosarcomas of the Chromosomal Regions Containing Rb, p16, p53, Cycline D1, APC, erbB2 and C-met Genes

At present, the only recognised prognostic factor for primary high-grade osteosarcoma is the histological response to preoperative chemotherapy. Our study was designed to identify new diagnostic markers that could eventually have a prognostic value and therapeutic consequences. 80 patients under 20 years of age with primary osteosarcomas were studied while under treatment by the French Society of Paediatric Oncology OS 94 protocol. Paired normal and biopsy samples were collected. In addition, surgical resection specimens, following preoperative chemotherapy, were obtained in many cases. After genomic DNA extraction, an allelotyping analysis targeting microsatellites was planned. The studied DNA regions contained mainly Rb, p53, APC, p16, c-met, TWIST, c-kit, erbB2 and topoisomerases genes. The techniques used in this molecular analysis comprised mainly allelotyping study, quantitative real-time PCR, gene sequencing , immunohistochemistry. The first results showed the prognostic value of 7q31 region containing c-met and 5q21 containing APC (Br J Cancer, 2003, Entz-Werlé et al.), 7p21 containing TWIST (Int J Cancer, 2005, Entz-Werlé et al.) and 4q21 targeting c-kit gene (J Clin Oncol, 2005, Entz-Werlé et al.).

What is being measured

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

Questions about this trial

What is this clinical trial studying?

An observational study of Paediatric Osteosarcomas, run by University Hospital, Strasbourg, France 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 2 inclusion and 0 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 30 Aug 2011. 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?

Presence of molecular abnormalities statistically linked to survival or response to chemotherapy. 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 30 Aug 2011.
