About this study

Official title: Screening of Genetic Susceptibility Genes for Breast Cancer Patients and Establishment of High-risk Populations in Chinese Communities

This is a community-based prospective study and the research object is breast cancer patients. It is planned to take the community as the unit to inform and collect the breast cancer patients who voluntarily participate to carry out the detection of BRCA1, BRCA2, PTEN, CHEK2 and PALB2 genes through the community health service center.

Read the detailed description

This is a population-based, prospective, cohort study which has been ongoing in 3 provinces of eastern China since 2019. Up to 5000 breast cancer survivors will conduct BRCA1, BRCA2, PTEN, CHEK2, and PALB2 genetic susceptibility genes testing, fill in clinical and genetic information forms, and collect family history. Mutation rate of BRCA1/2 and other genetic susceptibility genes in Chinese community breast cancer population will be measured. Logistic regression will be performed to establish a prediction model for the probability of BRCA1/2 and other gene mutations. Kin-Cohort method will be used to calculate the penetrance of breast cancer and other common malignancies in BRCA1/2 and other genetic mutation carriers.

What is being measured

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

  1. The frequency of pathogenic or likely pathogenic variants of BRCA1/2 and other genetic susceptibility genes in Chinese community breast cancer population

    The frequency of pathogenic or likely pathogenic variants and 95% confidence intervals of BRCA1/2 and other genetic susceptibility genes in Chinese community breast cancer population will be measured. After stratifying according to the different clinical characteristics of the patients, chi-square tests will be use to compare the mutation rates of BRCA1/2 gene in different subgroups.

    Measured: 1 year

Secondary outcomes (2)
  1. Prediction model of Genetic Susceptibility Gene (BRCA1/2 etc) mutation probability

    Logistic regression will be performed to establish a prediction model for the probability of pathogenic or likely pathogenic variants of BRCA1/2 and other genes. Candidate predictors included age, race or ethnic group, the mean number of tumor in a family etc. Missing data were imputed using multiple imputation by chained equations if needed. Model validation is based on k-fold cross validation approach. Model calibration and discrimination were evaluated using HL test and AUC, respectively. ORs and corresponding 95% CI will report.

    Measured: 1 year

  2. Breast cancer penetrance of Genetic Susceptibility Gene (BRCA1/2 etc) carriers

    Kin-Cohort method will be used to calculate the penetrance of breast cancer and other common malignancies in BRCA1/2 and other genetic mutation carriers.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Cancer and Genetic Susceptibility, run by Fudan University at 1 site in China.

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 3 inclusion and 3 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 31 May 2023. 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 China. 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?

Contact Zhen Hu, MD (86 21 64175590 ext. 65010, zhenhu@fudan.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The frequency of pathogenic or likely pathogenic variants of BRCA1/2 and other genetic susceptibility genes in Chinese community breast cancer population (time frame: 1 year). 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 NCT04265937, which also lists 1 linked publication.

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 31 May 2023.
