About this study

Official title: QUANTIFICATION OF CIRCULATING ENDOTHELIAL CELLS (CEC) AND PLASMA ANGIOGENIC FACTORS IN PATIENTS WITH BREAST CANCER

RATIONALE: Studying samples of blood in the laboratory from patients with current or previous cancer may help doctors learn more about biomarkers related to cancer.

PURPOSE: This research study is looking at blood samples in women with breast cancer or a history of breast cancer.

Read the detailed description

OBJECTIVES:

Primary

  • To compare peripheral blood (PB) concentrations of circulating endothelial cells (CEC) in women with measurable, active breast cancer to PB concentrations of CEC in a control population of women with a history of breast cancer who are currently without evidence of active disease.

Secondary

  • To compare in women with measurable breast cancer the relationship between PB concentrations of CEC prior to and at 3 and 6 weeks following initiation of a new chemotherapy or hormonal therapy, and correlate these values with clinical response to treatment to determine if CEC can be used as a tumor marker or indicator of disease burden.
  • To compare PB concentrations of CEC to levels of plasma proteins associated with angiogenesis, including vascular endothelial growth factor, in women with active or a prior history of breast cancer.

OUTLINE: Peripheral blood and plasma samples are collected for analysis of circulating endothelial cells (CEC) and angiogenic growth factor levels. Blood samples from patients initiating a new chemotherapy or hormonal therapy for breast cancer are collected at baseline and at 3 and 6 weeks following the start of treatment. CEC are quantified via flow cytometry and plasma angiogenic markers are assessed via ELISA.

PROJECTED ACCRUAL: A total of 100 patients with active, measurable breast cancer and 100 patients with a prior history of breast cancer will be accrued for this study.

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Cancer, run by University of Arizona at 1 site in United States.

The full registered description is in the About this study section and the official record.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Dec 2012. 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?

Comparison of levels of peripheral blood (PB) circulating endothelial cells (CEC) and plasma angiogenic factors between patients with active, measurable breast cancer vs prior history of breast cancer with no evidence of active disease. 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 17 Dec 2012.
