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.

Condition Intervention Phase
Breast Cancer Metastatic Breast Carcinoma Invasive Breast Carcinoma Drug: Carboplatin Drug: Cyclophosphamide Drug: Thiotepa Procedure: Stem Cell Transplant Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Phase II Study of Purging of Circulating Tumor Cells (CTCs) From Metastatic Breast Cancer Patients

Further study details as provided by M.D. Anderson Cancer Center:

Primary Outcome Measures:
  • 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 ]
    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.

Secondary Outcome Measures:
  • Median Progression Free Survival (PFS) [ Time Frame: Overall study (baseline to disease progression) ]
    Kaplan-Meier estimate of the median time from randomization to death from any cause or first observed disease progression. PFS time measured in months.

  9. Adequate renal function (serum creatinine <= 1.5mg/dl)
  10. Adequate liver function (total bilirubin, serum glutamate pyruvate transaminase (SGPT) <= 2 times normal).
  11. Adequate cardiac function (Left ventricular ejection fraction (LVEF)>= 50%).
  12. Adequate pulmonary function (Carbon Monoxide Diffusing Capacity (DLCO)>= 50% of predicted value).
  13. Females of childbearing (women who are post-menopausal < 1 year, not surgically sterilized, or not abstinent) potential must use adequate contraception.
  14. Patients must sign an informed consent.

Exclusion Criteria:

  1. Prior HDCT with Autologous hematopoietic stem cell transplantation (AHST) in adjuvant setting.
  2. History or presence of brain/leptomeningeal metastasis.
  3. History of other malignancies except cured non-melanoma skin cancer or cured cervical carcinoma in situ.
  4. Presence of other severe medical illnesses or conditions. Severe heart disease, (myocardial ischemia, myocardial infarction, etc.) Pulmonary disease (COPD, asthma,etc). Renal failure and hepatic failure.
  5. Clinically significant active infections (patient requiring IV antibiotics, uncontrolled infections, or hospitalized due to infections).
  6. HIV infection.
  7. Pregnant or lactating women.
  8. Medical, social or psychologic factors which would prevent the patient from receiving or cooperating with the full course of therapy or understanding the informed consent procedure.
