Brief Summary:
The primary aim of the study is to identify genomic markers (circulating tumor cells (CTCs), circulating tumor DNA (ctDNA), transcriptomic markers) as biomarkers of response to neoadjuvant chemotherapy (NAC) among patients with invasive breast cancer.

Condition or disease Intervention/treatment
Breast Cancer Breast Neoplasms Cancer, Breast Diagnostic Test: Genomic Markers (CTC/ctDNA)

Detailed Description:
The study aims to evaluate genetic markers (i.e. CTCs and ctDNA) in breast tumors to predict therapy response and metastatic risk. We aim to investigate genomic markers of treatment response and outcomes in breast cancer patients treated with neoadjuvant chemotherapy. The role of CTCs and ctDNA in predicting response to NAC will also be investigated.

Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Pathologic complete response (pCR) [ Time Frame: Up to 60 months ]
    Evaluating the degree of absence of residual cancer cells


Secondary Outcome Measures :
  1. Time to distant breast cancer recurrence (months) [ Time Frame: Up to 60 months ]
    Evaluating the time until a recurrence event has occurred in the breast.

  2. Time to any recurrence (months) [ Time Frame: Up to 60 months ]
    Evaluating the time until a local, regional, or distant recurrence event has occurred.

  3. Time to death [ Time Frame: Up to 60 months ]
    Evaluating time to cancer-related death

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
This study will enroll women and men with a pathologically-confirmed diagnosis of invasive breast cancer that is stage I-III according to the AJCC v7 criteria.
Criteria

Inclusion Criteria:

  1. Subjects must give appropriate written informed consent prior to participation in the study.
  2. Subjects must be women or men age 18+.
  3. Subjects must be receiving neoadjuvant chemotherapy for breast cancer. All chemotherapy types and regimens are acceptable (systemic therapy will determined by the overseeing medical oncologist).
  4. Biopsy-confirmed diagnosis of invasive breast cancer (i.e. ER+/-, PR+/-, HER2+/-).
  5. Stage I-III disease according to the AJCC v7 criteria.

Exclusion Criteria:

  1. Subjects with a past medical history of abnormalities, significant injury, or medical or surgical procedures (e.g. silicone/saline implants) involving either breast, exclusive of the lesion at issue.
  2. Subjects, who, in the opinion of the investigator or clinical research coordinator, may not otherwise be appropriate for inclusion into the study, such as significant anxiety.
