New breast cancer study findings reported from Mayo Clinic.(Report)

According to recent research published in the Menopause - the Journal of the North American Menopause Society, "Various nonestrogenic therapies have been found to be effective in mitigating hot flashes, but it has been unclear whether the efficacy varies by whether women have had breast cancer and/or were taking tarnoxifen. This Study used data from Mayo Clinic/North Central Cancer Treatment Group clinical trials that evaluated the efficacy of any nonestrogenic agent for hot flashes and had information on breast cancer history or tarnoxifen use."

"Statistically significant changes from the fourth treatment week versus the baseline week, using individual patient data, were assessed using Student's t test. A total of 1,396 women from 20 hot flash studies were eligible for analysis. Overall, women without breast cancer had a similar percentage of baseline hot flash score at week 4, as did those with breast cancer (53% vs 50%, P = 0.92). Women who were not taking tarnoxifen had a significantly lower percentage of hot flash score at week 4 as compared with those who used tarnoxifen (54% vs 61%, P = 0.01). However, this was due to a higher reduction in hot flash scores in the placebo arms among women not receiving tamoxifen; the percentage reduction in hot flash scores at week 4 from baseline in the active therapy arms of the randomized placebo-controlled trials (ie, excluding placebo arms) was ...
