Study Summary

Sorafenib may stop the growth of tumor cells by blocking blood flow to the tumor and by blocking some of the enzymes needed for cell growth. Estradiol can cause the growth of breast cancer. Hormone therapy using anastrozole may fight breast cancer by blocking the use of estradiol by the tumor cells. Sometimes when hormone therapy is given, it does not stop the growth of tumor cells. The tumor is said to be resistant to hormone therapy. Giving sorafenib together with anastrozole may reduce drug resistance and allow the tumor cells to be killed. This phase I/II trial is studying the side effects and best dose of sorafenib when given in combination with anastrozole and to see how well they work in treating postmenopausal women with metastatic breast cancer.

Primary Outcome

Clinical Outcome measured using Response Evaluation Criteria In Solid Tumors (RECIST,)V1.0, and assessed by MRI or CT: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Stable Disease (SD), a tumor that is neither growing nor shrinking. A patient has clinical benefit from treatment if CR + PR + SD \> 24 weeks.
