About this study

Official title: 1) Effects of Therapeutic Agents on Estrogens in the Breast 2) Utilizing the Resources of the Breast Cancer Collaborative Registry (BCCR)

RATIONALE: Studying samples of urine from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment.

PURPOSE: This research study is looking at urine samples from women with newly diagnosed breast cancer.

Read the detailed description

OBJECTIVES:

  • To learn the effects of selected agents (tamoxifen and aromatase inhibitors) on the profile of estrogen metabolites, glutathione conjugates, and depurinating DNA adducts in urine from women with breast cancer.

OUTLINE: Previously collected urine samples are analyzed for 40 estrogen metabolites, conjugates, and depurinating DNA adducts by ultra-performance liquid chromatography with tandem mass spectrometric detection.

Patient information (e.g., race, body mass index, age at menarche, menopausal status, age at menopause if applicable, smoking history, alcohol consumption) is collected through medical record review.

Conditions
Breast Cancer
Being tested
high performance liquid chromatography, laboratory biomarker analysis, mass spectrometry, medical chart review
Keywords
ductal breast carcinoma in situ, stage I breast cancer, stage II breast cancer, stage IIIA breast cancer, stage IIIB breast cancer, stage IIIC breast cancer, stage IV breast cancer
Medical subject headings
Breast Neoplasms, Carcinoma, Intraductal, Noninfiltrating

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • high performance liquid chromatographyOther

    Analyses of urine will be conducted by ultraperformance liquid chromatography with detection by tandem mass spectrometry.

  • laboratory biomarker analysisOther

    The biomarkers of interest will be the metabolites 4-OHE1(E2), estrogen-GSH conjugates and depurinating estrogen-DNA adducts.

  • mass spectrometryOther

    Analyses of urine will be conducted by ultraperformance liquid chromatography with detection by tandem mass spectrometry.

  • medical chart reviewOther

    Information about age, race, general health, any endocrine disorders, history of cancer, estrogen and progesterone receptor status, menopausal status and breast disease, body mass index, age at menarche, menopausal status (pre- or peri- menopausal or postmenopausal), age at menopause if applicable, chemotherapy regimen (if applicable), radiation therapy (if applicable), smoking history, alcohol consumption, pregnancy history including age at each pregnancy, lactation, history of benign breast disease, hysterectomy and disease type.

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Cancer, run by University of Nebraska at 1 site 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 5 inclusion and 2 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 1 Sep 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 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?

Estrogen compounds (time frame: at baseline at 6 months and annually). 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 1 Sep 2023.
