Any results on taking aromatase inhibitors for longer than 5 years?

Page last modified on: January 4, 2010

Question from Euro: When can we expect to hear results from studies on continuing aromatase inhibitors for longer than 5 years? Was there any discussion of this at the conference?: Answer —Kathy Miller, M.D.: This is a very important question, and there are two large clinical trials comparing 5 years of an aromatase inhibitor to 10 years. Both of those trials finished enrolling the number of patients they needed within the last 9-12 months, so we have not seen any results from those studies. It's difficult to predict when we will hear results, because that partly depends on whether there is any difference between the two treatment approaches. The bigger the difference, the sooner we can see those results and have confidence in the results. When the differences between two groups are small, it takes longer for us to see those results and have confidence that there really is a difference.
