Influence of aromatase inhibitors on plasma total homocysteine in postmenopausal breast cancer patients.

In this study, we evaluated the effect of estrogen suppression with three aromatase inhibitors, aminoglutethimide (n = 30), formestane (n = 12), and exemestane (n = 10), and the progestin megestrol acetate (n = 21) on plasma total homocysteine (tHcy) in patients suffering from advanced breast cancer. Treatment with 1 g/day aminoglutethimide for 2 and 3-5 months increased plasma tHcy by a mean value of 24.5% [95% confidence interval, 10.5-40.4%] at 2 months and 35.8% (95% confidence interval, 18.2-55.9%) at 3-5 months, corresponding to increases in the mean plasma tHcy of 1.90 and 3.67 micromol/L, respectively. In contrast, none of the other treatment options influenced plasma tHcy concentrations. The finding that aminoglutethimide, but none of the other aromatase inhibitors or megestrol acetate, influenced plasma tHcy suggests that this effect is achieved by mechanisms not related to suppression of plasma estrogens or to the glucocorticoids administered in concert.[1]
