A Randomized Phase II Trial of Combination Anastrozole (NSC #719344) Plus ZD1839 (Iressa, NSC #715055, IND #61187) and of Combination Fulvestrant (NSC #719276) Plus ZD1839 in the Treatment of Postmeno

Trial Conditions
  • Breast Cancer
What is the purpose of this trial?

RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using anastrozole and fulvestrant may fight breast cancer by blocking the use of estrogen. Gefitinib (ZD1839) may stop the growth of cancer cells by blocking the enzymes necessary for their growth. It is not yet known whether gefitinib is more effective when combined with anastrozole or fulvestrant in treating breast cancer. PURPOSE: This randomized phase II trial is studying how well giving gefitinib together with anastrozole works compared to giving gefitinib together with fulvestrant in treating postmenopausal women with recurrent or metastatic breast cancer.
