A premenopausal woman has ER-positive breast cancer, and her prescriber has ordered tamoxifen (Nolvadex). She asks the nurse if anastrozole (Arimedex) would work better for her. What will the nurse tell her?
a. Anastrozole is more likely to cause hot flushes than tamoxifen.
b. Anastrozole is more likely to promote endometrial carcinoma.
c. Cancer recurrence is higher with anastrozole.
d. Until she is postmenopausal, anastrozole will not be effective.
ANS: D
Anastrozole is used to treat ER-positive breast cancer in postmenopausal women. Because it does not block estrogen production in the ovaries, it is not effective in premenopausal women. It may cause hot flushes but is less likely to do so than tamoxifen. It is devoid of all estrogenic activity and does not promote endometrial cancer
