|Other: Blood draw|
Baseline blood draw.
|Other: Blood draw|
- The prevalence of breast cancer cells in the peripheral blood [ Time Frame: 1 year ]Specifically, it is predicted that 60% of subjects with Stage IV breast cancer will have evidence of breast cancer cells in the peripheral blood by multi-marker real-time RT-PCR analysis, and that these subjects will experience a significantly decreased progression-free and overall survival.
- Evaluate the prognostic significance of molecular detection of breast cancer cells in peripheral blood after initiation of systemic therapy. [ Time Frame: Until patient death ]Specifically, we will determine if molecular detection of circulating breast cancer cells after the initiation of systemic therapy is associated with a significantly decreased progression-free and overall survival.
- Quantify baseline molecular marker expression levels in the peripheral blood of healthy volunteers [ Time Frame: Approximately 12 weeks ]Determine if baseline molecular marker expression levels are dependent on patient age, race, and/or the presence of benign breast disease.
- Compare molecular analyses to the results of the CellSeach assay [ Time Frame: Approximately 12 weeks ]
