Q

Which chemotherapy agents are used in postmenopausal women, and why aren’t they effective in premenopausal women?

A
  • Aromatase inhibitors
  • Premenopausal females produce estradiol. Postmenopausal females produce very little estradiol and instead get most of their estrogen from the peripheral conversion of androgens. AIs don’t block ovarian estradiol production, which is why they aren’t useful in premenopausal females.
