Research on Evista for osteoporosis, recurrence?


Question from WRDS: I had breast cancer almost 4 years ago and have been on Arimidex for 3 1/2 years. I've developed osteoporosis due to Arimidex and Lupron injections for ovarian ablation. Has there been any research to prove the effectiveness of Evista to treat both the osteoporosis and to prevent a breast cancer recurrence in postmenopausal women who have completed the 5-year course of aromatase inhibitors?
Answers - Generosa Grana, M.D., F.A.C.P There is no data on Evista in the setting of breast cancer. The only data that is available, as we discussed earlier, is in women with osteoporosis and women at increased risk of breast cancer. So it is speculation to suggest that, after 5 years of an aromatase inhibitor, Evista will give you benefit in terms of recurrence. It is a drug that can be used to treat osteoporosis, but we clearly have more effective drugs in that setting. So I tend to dissuade my patients from Evista after tamoxifen use or aromatase inhibitor use because of the lack of data.
