Purged Circulating Tumor Cells (CTCs) From Metastatic Breast Cancer
The goal of this clinical research study is to learn the relationship of high-dose chemotherapy (HDCT) and circulating tumor cells (CTCs) in controlling metastatic breast cancer. The study also will investigate the role of CTCs in breast cancer.

|Official Title:||Phase II Study of Purging of Circulating Tumor Cells (CTCs) From Metastatic Breast Cancer Patients|
- Number of Participants With Reduction in CTCs Following High-dose Chemotherapy With Purged Autologous Stem Cell Products [ Time Frame: Baseline to 1 month post AHST ] [ Designated as safety issue: No ]Number of circulating tumor cells (CTCs) measured at one month post autologous hematopoietic stem cell transplantation (AHST), considered both as longitudinal values and compared to the baseline number of CTCs.
- Median Progression Free Survival (PFS) [ Time Frame: Overall study (baseline to disease progression) ] [ Designated as safety issue: No ]Kaplan-Meier estimate of the median time from randomization to death from any cause or first observed disease progression. PFS time measured in months.
