- Question from GranBelle: I've heard different things about Iressa—that it works in breast cancer, and that it doesn't work in breast cancer. Which is it?
- Answers - Andrew D. Seidman, M.D. When you phrase the question that way, the answer is it doesn't work in breast cancer. By this, I refer to at least four Phase 2 clinical trials that have shown either no or very minimal effectiveness for Iressa when used as a single agent or single drug. However, based on the evidence that inhibiting the epidermal growth factor receptor and estrogen receptor may translate into benefit not only in the laboratory but in patients, there are still clinical trials examining the potential for Iressa and anti-estrogen strategies such as tamoxifen and aromatase inhibitors in combination.
- Jennifer Armstrong, M.D. Excellent question, and excellent response. Thank you very much.
