Genetic Aspects of Chordoma: A Collaboration With SEER Registries to Identify Chordoma Families
An observational study of Chordoma, run by National Cancer Institute (NCI) at 2 sites in United States.
Trial summary
Chordoma is an uncommon (400 case/year in the U.S.) and potentially fatal bone tumor derived from remnants of embryonic notochord. It occurs primarily in the axial skeleton and has a mean age at diagnosis of 55 years, with a range from early childhood to over 70 years. Read more about this study

About this study
Chordoma is an uncommon (400 case/year in the U.S.) and potentially fatal bone tumor derived from remnants of embryonic notochord. It occurs primarily in the axial skeleton and has a mean age at diagnosis of 55 years, with a range from early childhood to over 70 years. This tumor usually presents at an advanced stage and the associated mortality is high due to local destruction and distant metastases. Chordoma is rare in African-Americans and is typically sporadic; there are few reports of these tumors arising congenitally or within members of the same family.
Recently, we have identified and studied one large family in which 10 relatives in three generations have chordoma; the inheritance pattern suggests transmission of a mutation in an autosomal dominant gene. Using information from this family, we have tentatively napped this gene to the long arm of chromosome 7. To confirm this finding, and to fine map and clone the gene, we need to study additional chordoma families. In an effort to identify such families, we have developed collaborations with four SEER registries covering the populations of Detroit, Los Angeles, Iowa, and New Mexico. Each registry will identify all chordoma cases diagnosed since 1988 and invite them (or the next of kin of deceased cases) to participate in our study. Through 1997, the registries have identified a total of 140 chordoma cases, 96 of whom are living. The registries will invite these patients (or their next of kin) to participate in the study. The study components include completion of a self-administered personal and family medical history questionnaire, retrieval of medical records and pathology reports pertaining to chordoma, and collection of paraffin-embedded chordoma tissue and buccal mucosal cells for genetic studies. NCI will carry out all the data collection activities for the study subjects identified through the Detroit registry. NCI will also conduct the buccal cell collection component of the study for all patients identified by the other three registries. These three registries will carry out all other study activities on these patients/next of kin and will send the data and slides prepared from the paraffin blocks to NCI. NCI will analyze the questionnaire data to determine if any unusual patterns of cancers other than chordoma or other medical conditions appear to cluster in families of the chordoma patients. Selected members of any families with two or more relatives with chordoma will be invited to participate in a separate clinical and molecular study conducted at NIH to try to identify the chordoma gene. DNA from the buccal cells and tumor blocks from all other patients with "sporadic" chordoma identified through the registries (likely to comprise most patients) will not be studied until we or others have identified such a gene.

Chordoma is an uncommon (400 case/year in the U.S.) and potentially fatal bone tumor derived from remnants of embryonic notochord. It occurs primarily in the axial skeleton and has a mean age at diagnosis of 55 years, with a range from early childhood to over 70 years. This tumor usually presents at an advanced stage and the associated mortality is high due to local destruction and distant metastases. Chordoma is rare in African-Americans and is typically sporadic; there are few reports of these tumors arising congenitally or within members of the same family.
In 1996, we have identified and studied one large family in which 8 relatives in three generations have chordoma; the inheritance pattern suggests transmission of a mutation in an autosomal dominant gene. Using information from this family, we tentatively mapped this gene to the long arm of chromosome 7. To confirm this finding, and to fine map and clone the gene, we needed to study additional chordoma families.
In an effort to identify such families, we have developed collaborations with four SEER registries covering the populations of Detroit, Los Angeles, Iowa, and New Mexico.

Questions about this trial
What is this clinical trial studying?
An observational study of Chordoma, run by National Cancer Institute (NCI) at 2 sites in United States.
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 1 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 10 Jul 2020. 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 United States. 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?
Identification of families containing multiple cases of Chordoma. (time frame: Ongoing). 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 NCT00341627, which also lists 3 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 10 Jul 2020.
