About

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.

Full 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.

Experimental group

Description:

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.

Treatment:

Drug: Celecoxib
