About
This study is being conducted in patients with newly diagnosed breast cancer that will be undergoing chemotherapy prior to surgery - neoadjuvant chemotherapy. The study involves treatment with standard chemotherapy and a commonly used, FDA-approved, blood pressure drug called propranolol (Inderal). The purposes of this study are to:
- Determine the effect of propranolol plus chemotherapy on breast cancer cells as well as the growth of blood vessels surrounding breast cancer cells.
- Determine the side effect profile of propranolol and chemotherapy in patients with breast cancer receiving neoadjuvant chemotherapy.
This research is being done because previous laboratory work has shown that propranolol may decrease the ability for the blood vessels around breast cancer cells to grow, which may be important in helping cancer cells grow. It also may reduce the likelihood for breast cancer cells to spread. If changes are seen in the breast cancer cells and surrounding blood vessels in this study, we will pan to evaluate whether propranolol decreases the likelihood of breast cancer from recurring in future, later studies. All chemotherapy regimens used in this study have been the standard of care for many years; however, the use of propranolol is being researched along with the chemotherapy regimens.
Full description
While a number of therapeutic options exist for patients with breast cancer (BC), breast tumor biology is differs across tumors and not all BCs respond to treatment. Identifying a marker predicting response could spare non-responders unnecessary side effects, cost, and time. A recent example in BC is bevacizumab, an expensive anti-angiogenic monoclonal antibody, for which the FDA revoked approval for patients with metastatic BC. While this targeted therapy may benefit some patients, no appropriate predictive marker has been identified in the drug development process. An ideal biologic marker would be easy to perform, reliable, low-cost and non-invasive. A limitation of assessing tumor-based markers in metastatic BC is the inability to procure tumor tissue at different treatment times. To circumvent this issue, anti-cancer agents can be assessed pre-operatively, where women with newly diagnosed BC receive a study drug, alone or with chemotherapy, between diagnostic breast biopsy and surgical resection. In addition, tumor changes can be directly compared to modulation of non-invasive markers, such as functional radiographs or blood, to identify a non-invasive marker predicting tumor response.
The investigators are conducting a neoadjuvant single-institution trial with the non-selective, inexpensive β -blocker propranolol with chemotherapy in locally advanced BC. β-blockade regulates angiogenesis in primary breast tumors. In these trials, the investigators plan to evaluate treatment-related microvascular response via changes in breast Diffuse Optical Tomography (DOT), a non-invasive, fast, safe, and inexpensive breast imaging tool. As the optical property contrast from endogenous chromophores (oxyhemoglobin, deoxyhemoglobin, water, and lipid) provides information on tissue vascularity, it can monitor response to anti-angiogenic agents. DOT changes occur as early as 1 week after starting pre-operative therapy. The dynamic DOT system incorporated in these trials is unique to Columbia University Medical Center (CUMC), as it has been designed by Columbia biomedical engineers. CUMC's laboratory collaborators have measured this DOT system with anti-angiogenesis agents in animal models, demonstrating the translational nature of this project. While non-dynamic DOT has been assessed in other neoadjuvant trials with small cohorts receiving heterogeneous chemotherapy agents, none have evaluated DOT response to anti-angiogenic agents.
