Ask-the-Expert Online Conference

Question from Amma: Does anyone have any input on taking Arimidex longer than the five-year mark? I took tamoxifen for two years and Arimidex for three, and my doctor says continuing might be beneficial.
Answers - Lynn Hartmann That's a good question, and we're looking for answers to that with ongoing clinical trials. The clinical trial that looked at Femara (chemical name: letrozole), an aromatase inhibitor similar to Arimidex (chemical name: anastrozole) or Aromasin (chemical name: exemestane), examined five years of Femara after five years of tamoxifen. Now it is looking at five additional years of Femara (a total of 10 years) compared to placebo. Your question is a good one, but I don't know a specific answer at this time. And most physicians are stopping after two to three years of tamoxifen plus two to three years of an aromatase inhibitor.
