Filter by:The study is being conducted to determine whether neoadjuvant endocrine therapy with fulvestrant or the combination of anastrozole and fulvestrant, is better than anastrozole when given before surgery to shrink the cancer and stop it from growing. Anastrozole inhibits tumor growth by reducing the levels of estrogen and has been approved by the Food and Drug Administration (FDA) of the United States for use after surgery for postmenopausal women with estrogen receptor positive breast cancer. It is also considered a standard of care to give anastrozole for a few months before surgery to shrink the tumor. Fulvestrant inhibits tumor cell growth by reducing the levels of estrogen receptor in the tumor cell. It is not approved by the FDA for use in women with early stage breast cancer before or after surgery, but is approved by the FDA for patients with advanced (Stage 4) estrogen receptor positive breast cancer that has spread to other parts of the body.
This randomized phase III trial studies metformin hydrochloride to see how well it works compared to placebo in preventing breast cancer in patients with atypical hyperplasia or in situ breast cancer. Chemoprevention is the use of certain drugs to keep cancer from forming. The use of metformin hydrochloride may prevent breast cancer.
This pilot clinical trial studies new ways to monitor the impact of hypofractionated image guided radiation therapy in treating patients with stage IV breast cancer. Radiation therapy uses high energy x rays to kill tumor cells. Giving radiation therapy in different ways may kill more tumor cells.
RATIONALE: DNA analysis of tumor tissue may help doctors predict how well patients will respond to treatment and plan effective treatment. PURPOSE: This pilot study is studying how well hormone therapy or chemotherapy before surgery based on gene expression analysis works in treating patients with breast cancer. The purpose of this research study is threefold. First, it is to determine if this approach to treatment is acceptable to participants. Second, it is to determine whether it is feasible to use the genetic make-up of your breast cancer cells to predict whether your disease will best respond to chemotherapy or hormonal therapy when given prior to surgery. Third, which is optional, is to determine if the blood levels of Insulin-like growth factor binding protein-2 IGFBP-2 can be used to monitor the response of your breast cancer to the treatment that you receive.
A PET scan drop less than 20% in SUVs or below a certain absolute SUV value after the first course of neoadjuvant chemotherapy can predict pathological response, and could in the future lead to an early surgical intervention.
