In the past decade, therapies other than estrogen plus progestogen have been increasingly studied (<a class="elsevierStyleCrossRef" href="#bib1">1</a>), and it has become accepted that successful treatment depends on individual assessment of a woman's needs and the consequent analysis of the risk-benefit profile. Among the selective estrogen receptor modulators (SERMs) and compounds with varying affinities for estrogen receptors in different target tissues, raloxifene acts as an estrogen agonist on the bone and serum-lipid metabolism, and as an estrogen antagonist in the breast and uterus (<a class="elsevierStyleCrossRefs" href="#bib2">2–8</a>). Raloxifene is currently approved for the prevention and treatment of postmenopausal osteoporosis and chemoprevention of invasive breast cancer (<a class="elsevierStyleCrossRef" href="#bib9">9</a>). In postmenopausal women with osteoporosis, raloxifene has been reported to decrease the risk for breast cancer by 66% (<a class="elsevierStyleCrossRef" href="#bib10">10</a>). However, despite the favorable profile, including endometrial safety, raloxifene may lead to increased occurrence of hot flashes and, as such, may not be well-tolerated.</p><p id="para20" class="elsevierStylePara elsevierViewall">Conjugated estrogens (CEs) have been confirmed to reduce hot flashes and are among the compounds that remain considered to be optimal for the treatment of vasomotor symptoms (<a class="elsevierStyleCrossRef" href="#bib1">1</a>). Hormone replacement therapy is often associated with a good benefit-risk profile in women <60 years of age and within 10 years of onset of menopause (<a class="elsevierStyleCrossRef" href="#bib1">1</a>). However, unopposed estrogens may induce endometrial proliferation in women with an intact uterus (<a class="elsevierStyleCrossRef" href="#bib1">1</a>). Low-dose estrogens, despite inducing less endometrial proliferation than standard doses (<a class="elsevierStyleCrossRef" href="#bib11">11</a>,<a class="elsevierStyleCrossRef" href="#bib12">12</a>), are administered in combination with progestogens to ensure long-term endometrial safety.</p><p id="para30" class="elsevierStylePara elsevierViewall">Because women undergoing estrogen plus progestogen therapy have been shown to have an increased risk for breast cancer (<a class="elsevierStyleCrossRef" href="#bib13">13</a>), in contrast to those treated with unopposed estrogen who appear to have a reduced risk (<a class="elsevierStyleCrossRef" href="#bib14">14</a>), in addition to the concerns regarding an increased risk for cardiovascular events raised by the Women's Health Initiative study, alternative options for hormone replacement therapy can be considered. Tissue-selective estrogen complex, which comprises the combination of estrogen with a SERM, has been explored in attempts to optimize hormone replacement therapy and reduce adverse outcomes (<a class="elsevierStyleCrossRef" href="#bib15">15</a>), including endometrial proliferation.

The combination of CE and raloxifene could potentially minimize the undesirable effects of estrogen on the uterus and breast tissues, and allow the beneficial agonistic effects of estrogen in other estrogen target-tissues (<a class="elsevierStyleCrossRefs" href="#bib25">25–29</a>).</p><p id="para40" class="elsevierStylePara elsevierViewall">The present study was part of a larger research project that aimed to compare low-dose CE alone <span class="elsevierStyleItalic">versus</span> raloxifene alone or a combination thereof in postmenopausal women at high risk for breast cancer.

Overall, our results are consistent with most previous studies involving combined estrogens and raloxifene, which reported benefits in menopausal symptoms.</p><p id="para210" class="elsevierStylePara elsevierViewall">The average ET at baseline in our study across the three groups was 2.16 mm, with no difference among the groups (<span class="elsevierStyleItalic">p</span>=0.661). The mean ET was not increased in the combination group when compared with baseline values or with the raloxifene group during the study. These results are consistent with other studies, which also did not identify significantly increased ET when raloxifene was combined with estrogens (<a class="elsevierStyleCrossRefs" href="#bib26">26–28</a>). On the other hand, two other studies (<a class="elsevierStyleCrossRef" href="#bib25">25</a>,<a class="elsevierStyleCrossRef" href="#bib29">29</a>) reported increased ET with the use of raloxifene combined with esterified CEs (0.312 mg/day) or 17-beta-estradiol (1 mg/day). The difference between these results and those of our study may be due to the different type of estrogen used and/or route of administration. Moreover, in the former study (<a class="elsevierStyleCrossRef" href="#bib25">25</a>), there was a numerically higher average ET in the pre-treatment phase, and the latter (<a class="elsevierStyleCrossRef" href="#bib29">29</a>) had statistically significant differences in average ET at 52 weeks when compared with baseline and raloxifene group, with two patients developing endometrial hyperplasia.</p><p id="para220" class="elsevierStylePara elsevierViewall">Genital bleeding, a commonly reported event in women who use estrogen, is related to dose and exposure time (<a class="elsevierStyleCrossRef" href="#bib33">33</a>). However, the use of low-dose estrogen (equivalent to 0.3 mg of CEs) dramatically reduces the incidence of genital bleeding (<a class="elsevierStyleCrossRef" href="#bib11">11</a>,<a class="elsevierStyleCrossRef" href="#bib33">33</a>). Although often considered a result of cell proliferation, genital bleeding is also commonly observed in women with endometrial atrophy (<a class="elsevierStyleCrossRef" href="#bib34">34</a>). This may explain the low incidence of this complaint in low-dose estrogen users, as reported in a two-year study (<a class="elsevierStyleCrossRef" href="#bib11">11</a>). In the present study, endometrial analysis was performed every 3 months to ensure that eventual early changes in ET would be promptly recognized and treated accordingly. Among the population studied, three women using low-dose CE alone experienced genital bleeding, and all three exhibited ET >5 mm on the first assessment by ultrasound after the bleeding. Of these, two were diagnosed with endometrial atrophy and one exhibited simple proliferative endometrium without atypia. Although four women in the combination group were noted to have ET >5 mm in our study, neither genital bleeding nor endometrium hyperplasia occurred in this group. Most clinical trials that assessed the combined use of raloxifene plus estrogens did not report the occurrence of genital bleeding (<a class="elsevierStyleCrossRefs" href="#bib26">26–28</a>).</p><p id="para230" class="elsevierStylePara elsevierViewall">The present study had a few limitations, the first of which was its small sample size. Moreover, some women included in this study had a high BMI, which, although homogeneous among the three groups, may have influenced the results. Obesity itself may cause increased ET because it contributes to the production of estrogens by adipose tissue. Investigating the correlation between endometrial thickening and obesity or a high BMI was beyond the scope of this trial and not feasible with this sample size. Strengths of the present study include the originality of the use of the combination of raloxifene and estrogen in postmenopausal women at high risk for breast cancer and quarterly assessment of the endometrium during the one-year study period. Additionally, the lack of published studies investigating marketed drug associations to treat common menopause in women makes this study clinically important.</p><p id="para240" class="elsevierStylePara elsevierViewall">Results of the present one-year study demonstrate the clinical similarity of endometrial findings between menopausal women receiving raloxifene alone and those receiving raloxifene plus low-dose CEs. These results are clinically significant and add to previously published studies that evaluated the combination of raloxifene and estrogens. To our knowledge, this is the first study to evaluate the effects of combined therapy using combined CEs in postmenopausal women at high risk for breast cancer. This specific patient population currently lacks a treatment option that is both safe and effective to both reduce the risk for cancer and to maintain good quality of life. We believe that larger studies investigating the safety of this association in postmenopausal women at high risk for breast cancer are warranted.</p></span><span id="cesec120" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cestitle170">CONCLUSION</span><p id="para250" class="elsevierStylePara elsevierViewall">This one-year trial demonstrated that combined raloxifene and low-dose CEs decreased the severity of menopausal symptoms to an extent similar to CE alone, and had effects similar to raloxifene alone on the endometrium.</p></span><span id="cesec130" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cestitle180">AUTHOR CONTRIBUTIONS</span><p id="para260" class="elsevierStylePara elsevierViewall">Carneiro ALB, Souza FA, Alves KBF, Araujo-Neto JT, Dardes RCM collected the clinical data.
