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