Trial summary

This is a cohort study, applied research and T3 translational genomics to estimate the impact of genetic risk for breast cancer detection in the screening program. The study group base consists of 28 389 female participants, currently in the age-group 22-79, in the Biobank of Estonian Genome Centre. Read more about this study

About this study

Official title: Implementation of a Model for Personalised Risk-Based Breast Cancer Prevention and Screening

This is a cohort study, applied research and T3 translational genomics to estimate the impact of genetic risk for breast cancer detection in the screening program. The study group base consists of 28 389 female participants, currently in the age-group 22-79, in the Biobank of Estonian Genome Centre. The study is aimed to demonstrate the usability of personalised approach for adjusting and stratifying screening recommendations, based on predicted genetic risk estimates for breast cancer in the situation, where the genome data could be available from all women who have given informed consent for that. The project includes both the detection of moderate and high hereditary breast cancer risk carriers as well as high risk polygenic risk-score (consisting several single nucleotide polymorphisms) carriers among healthy individuals for application of personalised prevention and screening strategies.

Questions about this trial

What is this clinical trial studying?

A study testing Mammography outside official screening in people with Breast Cancer, run by Tartu University Hospital at 2 sites in Estonia.

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 9 inclusion and 1 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: status not confirmed, as of the sponsor's last update on 20 Jun 2019. 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 Estonia. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of women in the population with genetically higher risk for breast cancer (time frame: 3 years). 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 20 Jun 2019.
