NCT ID NCT00579488

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study aims to learn more about how inherited gene mutations, particularly in the BRCA1 and BRCA2 genes, affect the risk of developing breast and ovarian cancer. Researchers will follow participants with a family history of these cancers, tracking their medical history and family information over time. The goal is to better measure cancer risks associated with known mutations and to search for other, yet undiscovered cancer-related genes. This knowledge could help improve cancer screening and prevention recommendations for people with a genetic predisposition.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
This research could lead to better ways to estimate cancer risk for people with BRCA mutations and help discover new cancer-related genes, improving screening and prevention strategies.
What could go wrong
The study is observational and long-term, so it may take years to yield actionable results. The suggested screening methods may not always be effective, and the findings may not apply to everyone.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Families referred for genetic counseling consultation at Memorial Hospital * Individuals self-referred or physician referred for genetic counseling due to a concern about increased risk for breast cancer, regardless of family history or ethnic origin. * Individuals enrolled in MSK protocol 97-029 "Germline BRCA1 and BRCA2 mutations in Jewish Women Affected by Breast Cancer" * Individuals who present for genetic counseling consultation at Memorial Hospital after undergoing genetic testing at an outside institution. * Member of a family with breast cancer who wishes to provide a DNA sample for research purposes * Individuals enrolled on protocol 12-245 with germline variants in genes associated with risk for breast or ovarian cancer, or absent such variants in the presence of a family history or other phenotypic features of interest including but not limited to: triple negative breast cancer, early onset of disease, and/or synchronous or metachronous breast and ovarian cancer. Exclusion Criteria: -Patients will be excluded from this study if: he/she has physical, cognitive or psychiatric conditions that interfere with ability to give meaningful informed consent; he/she cannot read, write or communicate in English; he/she is less than 18 years of age.
