Anastrozole With or Without Gefitinib in Treating Postmenopausal Women With Metastatic or Locally Recurrent Breast Cancer

Summary

RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using anastrozole may fight breast cancer by reducing the production of estrogen. Gefitinib may stop the growth of tumor cells by blocking the enzymes necessary for their growth. Combining anastrozole with gefitinib may kill more tumor cells. PURPOSE: Randomized phase II trial to compare the effectiveness of anastrozole with or without gefitinib in treating postmenopausal women who have metastatic or locally recurrent breast cancer.
