About

LHRH-a is an important hormone treatment in breast cancer especially in high-risk hormone receptor-positive patients or hormone receptor-negative but needing ovarian function protecting. The climacteric symptoms caused by LHRH-a are often and prominent, which is a common clinical problem.

Full description

Ovarian function suppression (OFS) or protection has been studied widely in breast cancer. As an common drug in clinic, LHRH-a is an important method for OFS in breast cancer especially in high-risk hormone receptor-positive patients or hormone receptor-negative but needing ovarian function protecting. The climacteric symptoms caused by LHRH-a are often and prominent, which is a common clinical problem. Remifemin (cimicifuga racemosa / black cohosh) is effective in climacteric symptoms as a hormone replacement treatment, some research concluded that it is also safe in breast cancer patients who are postmenopausal or taking tamoxifen suffering from climacteric symptoms. While in China, more than 2/3 breast cancer patients are pre/peri-menopause, and some part of them should take OFS as an hormone treatment. OFS can cause sever climacteric symptoms in a short time. The investigators aim to estimate the effect and safety of Remifemin in climacteric symptoms caused by OFS in breast cancer.
