Primary Outcome Measures:
  • Characterize tumor markers expressed by DTC which are present after chemotherapy. [ Time Frame: Approximately 6 years ] [ Designated as safety issue: No ]
  • Compare the expression of these markers to that on DTC detected prior to chemotherapy. [ Time Frame: Approximately 6 years ] [ Designated as safety issue: No ]
  • Correlate expression of the defined tumor markers on DTC with clinical outcome of breast cancer patients to identify those markers that are predictive of disease recurrence. [ Time Frame: Approximately 6 years ] [ Designated as safety issue: No ]
  • Compare the tumor markers present on DTC before and after chemotherapy with the tumor marker expression of the primary tumor and post-treatment tumor. [ Time Frame: Approximately 6 years. ] [ Designated as safety issue: No ]
  • To xenograft tumor cells into mice for further genetic and phenotypic characterization. [ Time Frame: Approximately 5-11 years. ] [ Designated as safety issue: No ]

Estimated Enrollment: 200
Study Start Date: September 2005
Estimated Study Completion Date: August 2016
Estimated Primary Completion Date: August 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Arm 1

Breast cancer tissue, peripheral blood, and bone marrow will be collected at that following times:

  • at the time of initial surgery for a sentinel lymph node biopsy or portacath placement
  • during definitive cancer surgery (if surgery occurs)
  • at one year, when portacath is removed (if available)
  • if metastatic disease (nodules, pleural effusion, or other metastatic disease) develops or is present in accessible sites, a sample may be collected at the time of specimen collection for diagnosis

All patients will undergo blood collection once a year for 5 years from the time of enrollment

Procedure: Blood draw

Detailed Description:

In this study, we propose that persistent disseminated tumor cells (DTC) present after chemotherapy represent a unique subpopulation of all DTC, are predictors of a poor response to chemotherapy, and correlate with poor clinical outcome. We hypothesize that chemotherapy-resistant DTC can be identified by their expression of a unique constellation of tumor marker proteins which may be similar to those expressed by breast cancer stem cells. In this research, our specific aims are : 1) to characterize tumor markers expressed by DTC which are present after chemotherapy, 2) to compare the expression of these markers to that on DTC detected prior to chemotherapy, 3) to correlate expression of the defined tumor markers on DTC with clinical outcome of breast cancer patients to identify those markers that are predictive of disease recurrence, 4) to utilize biomarkers identified in Specific Aims 1 and 2 to isolate purified DTC for further molecular analysis.
