Atorvastatin in Treating Patients With Stage IIb-III Triple Negative Breast Cancer Who Did Not Achieve a Pathologic Complete Response After Receiving Neoadjuvant Chemotherapy

This phase II trial studies how well atorvastatin works in treating patients with stages IIb-III triple negative breast cancer who did not achieve a pathologic complete response to neoadjuvant chemotherapy. Pathologic complete response is the lack of all signs of cancer in tissue samples removed during surgery after upfront chemotherapy. Atorvastatin is used for the treatment of high cholesterol and may reduce the risk of triple negative breast cancer from coming back. Triple-negative breast cancer is a type of breast malignancy that is comprised of cancer cells that do not have estrogen receptors, progesterone receptors, or large amounts of HER2/neu protein. Patients with TNBC do not have established systemic therapies such as anti-estrogens or HER2-targeting agents to reduce recurrence after surgery, and residual cancer found at surgery is associated with higher relapse rate.
