Brief Summary:
The overall purpose of this study is to assess whether celecoxib can reduce the change in collagen alignment and inflammatory response in the tumor tissue of primary breast cancer patients with invasive breast carcinoma after 2 weeks of oral intake.

Condition or disease Intervention/treatment Phase
Breast Carcinoma Drug: Celecoxib Phase 2

Detailed Description:
Advances in early detection techniques and improvement in systemic treatment of early stage breast cancer have led to a small decline in overall breast cancer mortality in the last 20 years. New advances will require understanding of breast cancer biology at the molecular level. Inhibition of COX-2 and its analysis of effect in breast cancer tumor microenvironment provide one such fruitful therapeutic target. Tumor microenvironment is poorly understood in breast cancer research. Despite new drugs being developed to treat breast cancer and tested in clinical trials, it is rarely possible to assess how the drug is affecting the breast cancer cells at a molecular level. The use of collagen properties such as alignment and deposition will allow giving a faster diagnosis of breast cancer status and seeing how celecoxib with respect to collagen can change the tumor microenvironment in human tissue. This window trial provides a way to look at cancer and stromal cells before and after celecoxib intake to see if the drug is actively working. If we can do this before and after a patient has surgery, and see how the tumor microenvironment responds, then the physician could pick a better suited adjuvant treatment for this patient after surgical intervention that would improve their overall survival rate.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 0 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Masking Description: Due to the characteristics of the design of this clinical trial, the patient will not be blinded but the researcher completing analysis will be. The researcher will be handling deidentified patient samples and comparing whether there are changes of biological markers within the same patient before and after celecoxib intake. It is important that the researcher be as unbiased as possible when analyzing collagen alignment and amount of other breast cancer biological markers.

Arm Intervention/treatment
Experimental: Celecoxib

The participants will be scheduled for the two quantitative breast MRI exams. Following the first MRI exam, participants will start taking celecoxib 200mg twice a day with food. Subjects will take a minimum of 26 doses and no more than 32 doses of celecoxib during the study.

Participants will intake 200mg of celecoxib two times a day (400mg/day total) for 2 weeks after biopsy. Histologic tissue samples will be obtained for evaluation at time of biopsy of the tumor and at time of surgery removal of the tumor.

Drug: Celecoxib
Celecoxib is the only COX-2 inhibitor currently approved by the FDA to be used in the United States. Recently, it has been shown that celecoxib prevents sporadic colorectal adenomas and there are more clinical trials evaluating the use of celecoxib in combination with chemotherapy regimens in breast cancer settings. Celebrex® oral capsules that will be used in this study contain 200 mg of celecoxib, in combination with inactive ingredients that include the following components: croscarmellose sodium, edible inks, gelatin, lactose monohydrate, magnesium stearate, povidone and sodium lauryl sulfate.
Other Name: Celebrex

Primary Outcome Measures :
  1. Changes in collagen [ Time Frame: Up to 6 weeks ]
    To determine change of collagen structure and proliferation in response to celecoxib intake in the tumor microenvironment.

Secondary Outcome Measures :
  1. Change in correlation of collagen alignment and COX-2 expression [ Time Frame: Up to 6 weeks ]
    To evaluate correlation among collagen alignment and COX-2 expression before and after celecoxib intake.

  2. Changes in Syndecan-1 [ Time Frame: Up to 6 weeks ]
    To analyze Syndecan-1 expression levels as stromal response biomarkers.

  3. Changes in CD68 [ Time Frame: Up to 6 weeks ]
    To analyze CD68 expression levels as stromal response biomarkers.

  4. Changes in CD163 [ Time Frame: Up to 6 weeks ]
    To analyze CD163 expression levels as stromal response biomarkers.

  5. Changes in neutrophil elastase [ Time Frame: Up to 6 weeks ]
    To analyze neutrophil elastase expression levels as stromal response biomarkers.

  6. Changes in vimentin [ Time Frame: Up to 6 weeks ]
    To analyze vimentin expression levels as stromal response biomarkers.

  7. Changes in α-SMA [ Time Frame: Up to 6 weeks ]
    To analyze α-SMA expression levels as stromal response biomarkers.

  8. Changes in Ki67 [ Time Frame: Up to 6 weeks ]
    To analyze Ki67 expression levels as stromal response biomarkers.

  9. Changes in tissue cytokines in dense breast tissue [ Time Frame: Up to 6 weeks ]
    To discover tissue cytokines present in dense breast tissue that are altered in response to celecoxib.

  10. Number of subjects with adverse events associated with celecoxib [ Time Frame: Up to 6 weeks ]
    To evaluate any adverse events associated with the 2-week intake of 200mg celecoxib twice a day.

  11. Changes in collagen due to relationship of amount/percentage of fibroglandular tissue [ Time Frame: Up to 6 weeks ]
    To determine if changes in collagen structure and proliferation in response to celecoxib differ by the amount and/or percentage of fibroglandular tissue, measured quantitatively using MRI.
