ABSTRACT: Effects of Tamoxifen Versus Raloxifene on the Risk of Developing Invasive Breast Cancer and Other Disease Outcomes Background and Objectives: Tamoxifen is a selective estrogen receptor modulator (SERM) that has been approved for the reduction of both invasive and noninvasive breast cancer risk among high-risk women. Raloxifene is a second-generation SERM that has been shown to reduce the risk of breast cancer among older women with osteoporosis. The purpose of the current study was “to compare the relative effects and safety of raloxifene and tamoxifen on the risk of developing invasive breast cancer and other disease outcomes. Methods: The current trial was a double-masked, randomized experimental study conducted among high-risk postmenopausal women from approximately 200 clinical institutions in North America. Study subjects included 19,747 women whose mean age was 58.5 years at enrollment. Women were randomized to receive either oral tamoxifen (20 mg/d) or raloxifene (60 mg/d) for a maximum of 5 years. The primary outcome was the incidence of invasive breast cancer. Secondary outcomes included the incidence of uterine cancer, noninvasive cancer, bone fractures, and thromboembolic events. Results: A total of 163 cases of invasive breast cancer occurred in the tamoxifen group as compared with 168 cases in the raloxifene group (incidence, 4.30 per 1,000 versus 4.41 per 1,000, risk ratio [ RR ], 1.02; 95% confidence interval [ CI ], 0.82–1.28). Only 57 cases of noninvasive breast cancer occurred in the tamoxifen group as compared with 80 raloxifene group (incidence, 1.51 versus 2.11 per 1,000; RR, 1.4; 95% CI, 0.98–2.00). A total of 36 cases of uterine cancer occurred in the tamoxifen group while 23 cases occurred in the raloxifene group (RR, 0.62; 95% CI, 0.35–1.08). No differences were seen for other invasive cancers, ischemic heart disease, or stroke. Thromboembolic events and cataracts occurred less often in the raloxifene group (RR, 0.70; 95% CI, 0.54–0.91 for thromboembolic events and RR, 0.79; 95% CI, 0.68–0.92 for cataracts). The frequency of osteoporotic fractures was similar in both groups. Conclusions: Raloxifene and tamoxifen are equally effective in reducing the risk of invasive breast cancer but raloxifene does not reduce the risk of noninvasive breast cancer. Raloxifene has a lower risk of thromboembolic events and cataracts and a similar risk of osteoporotic fractures as tamoxifen.
