| Creasman WT. Is There an Association between Hormone Replacement Therapy and Breast Cancer? J Women’s Health 1998; 7(10) | “In aggregate, these data fail to provide definitive evidence that the use of postmenopausal HRT is associated with an increased incidence of breast cancer.” |
| Nachtigall LE. Sex Hormone-Binding Globulin and Breast Cancer Risk Primary Care Update for Ob/Gyns 1999; 6 (2):39-45. | “Extensive epidemiologic studies provide conflicting evidence as to whether ERT significantly impacts the risk of breast cancer in postmenopausal women…”“The increase in SHBG promoted by oral ERT, and especially by oral conjugated estrogens, might contribute to the favorable epidemiologic data for this class of estrogens with respect to the breast cancer rate. ” |
| Eden J. Progestins and breast cancer. Am J Obstet Gynecol. 2003 May;188(5):1123-31. | “… studies have clearly demonstrated that prior or current HRT use results in a paradoxically improved survival for patients with breast cancer.”“…results from epidemiologic studies are inconsistent and mechanistic studies have not provided a physiologic foundation to implicate progestin in the pathogenesis of breast cancer.” |
| Cefalu T. The Use of Hormone Replacement Therapy in Postmenopausal Women with Type 2 Diabetes. J Women’s Health 2001; 10 (3):241-255 | “Although a possible risk has been shown in long-term users, a causal relationship between ERT/HRT and breast cancer remains controversial.” |

| Fillit, M. The Role of Hormone Replacement Therapy in the Prevention of Alzheimer Disease. Arch Intern Med. 2002;162(17):1934-42. | “At present, most observational evidence, which is supported by neurobiological research findings on the action of estrogen, indicates that ERT/HRT mitigates the degeneration that may lead to AD. The lack of evidence of a role of estrogen in the treatment of AD suggests that ERT/HRT should be initiated as early as possible after menopause, before the onset or the progression of the disease.” |
| Birge SJ. Practical Strategies for the Diagnosis and Treatment of Alzheimer’s Disease. Clinical Geriatrics 1999 7(4):56-74. | “Estimates of the annual cost of AD per individual range from $34,000 to $47,000, with the annual overall cost to society estimated at $67 billion.”“…effective treatment in the form of disease prevention or delayed expression would significantly decrease the financial burden to both the individual and society. Delaying institutionalization by just one month would reduce that cost by 1.2 billion dollars.” |
| Shulman L. Is there a Connection Between Estrogen and Parkinson’s Disease? Parkinsonism Relat Disord. 2002;8(5): 289-95 | “Increasing evidence suggests that estrogens may protect the nigrostriatal dopaminergic pathway affected in Parkinson’s disease (PD).” |
| Sherwin BB. Mild Cognitive Impairment: Potential Pharmacological Treatment Options. J Am Geriatr Soc. 2000;48(4):431-41. | “Estrogen, in particular, deserves more attention because its cognitive-enhancing properties, which have been verified by several controlled clinical trials, are complemented by its potential for preventing cardiovascular disease and osteoporosis and for reducing the risk of colorectal cancer and all-cause mortality in postmenopausal women.” |
| Brincat M, Baron Y, Galea R. Estrogens and the Skin. Climacteric 2005;8(2):110-23. | “Estrogen treatment in postmenopausal women has been repeatedly shown to increase collagen content, dermal thickness, and elasticity. … Physiologic studies on estrogen and wound healing suggest that HRT may play a beneficial role in cutaneous injury repair; however, molecular studies have yet to articulate the mechanisms.” |
| Snow KK, Seddon JM. Age-Related Eye Diseases: Impact of Hormone Replacement Therapy and Other Risk Factors. Int J Fertil Womens Med. 2000 Sep-Oct;45(5):301-13 | “Evidence suggests that among women, long-term exposure to endogenous estrogens or replacement estrogens may reduce the risk of AMD and cataracts. … The potential value of this therapy in reducing visual impairment among women deserves increased attention.” |
| Freedman, MA.Quality of Life and Menopause: The Role of Estrogen.J Women’s Health 2002;11(8):703-718. | “Less attention has been paid to the menopausal symptoms that can impair the quality of life of menopausal women, such as hot flushes, sleep disorders, sexual dysfunction, and alterations in mood… Evidence supporting the effectiveness of ERT/HRT in the treatment of symptoms affecting quality of life is growing and supports the use of ERT/HRT during menopause.” |
| Bachman G, Leiblum S. The Impact of Hormones on Menopausal Sexuality: a Literature Review. Menopause 2004;11 (1): 120-130. | “Estrogen deficiency initially accounts for altered bleeding and diminished vaginal lubrication. Continual estrogen loss often leads to numerous signs and symptoms, including changes in the vascular and urogenital systems. Alterations in mood, sleep, and cognitive functioning are common as well. These changes may contribute to lower self-esteem, poorer self-image, and diminished sexual responsiveness and sexual desire.” |
| Cefalu T. (above) | ”The potential in a diabetic population for improved insulin and glucose metabolism, as well as reduced risk of CVD, with the use of ERT/HRT has been shown in several prospective studies.” |
| Gallagher JC. | “The beneficial effects of estrogen on the prevention of osteoporosis are likely to carry over to improved dental health in women.” |
|

| Gallagher JC. Role of Estrogens in the Management of Postmenopausal Bone Loss. Rheum Dis Clin North Am. 2001;27(1):143-62. | “ERT remains the therapy of choice because of its long-term effect on BMD and because estrogen has other favorable systemic benefits in addition to the prevention of osteoporosis.”“Of the oral preparations, the best studied in postmenopausal women has been conjugated equine estrogens ([CEE] Premarin). “ |
| Mosca L. The Role of Hormone Replacement Therapy in the Prevention of Postmenopausal Heart Disease, Arch Intern Med. 2000 Aug 14-28;160(15):2263-72. | “The results of preclinical studies with SERMs suggest smaller cardiovascular effects than those seen with HRT.” |
| Warren M. A Comparative Review of the Risks and Benefits of Hormone Replacement Therapy Regimens. Am J Obstet Gynecol. 2004 Apr;190(4):1141-67 | “Overall, these data indicate that the benefit/risk analysis that was reported in the Women's Health Initiative can be generalized to all postmenopausal hormone replacement therapy products.” |
| Curtis M. Selective Estrogen Receptor Modulators: A Controversial Approach for Managing Postmenopausal Health. J Women’s Health 1999; 8 (3) : 321-33 | “HRT, the current standard of care, has the advantage of long-term epidemiologic data that indicate that the benefits of therapy clearly outweigh the risks. In contrast, the risk:benefit of the emerging SERMs needs to be better defined and evaluated.”“The clinical use of SERMs has yet to demonstrate beneficial effects shown with HRT on all-cause mortality, colon cancer, and central nervous system function (i.e., reduced risk of Alzheimer's disease, improve cognition).” |
| Curtis MG. Comparative Tolerability of First-Generation Selective Estrogen Receptor Modulators in Breast Cancer Treatment and Prevention. Drug Safety 2001;24(14):1039-53 | “At present, each potential adverse event needs to be weighed against potential benefits in the decision to undergo SERM treatment…”“The development of future generations of SERMS that improve upon the current therapies is eagerly anticipated.” |
| Bachmann GA. Menopausal Vasomotor Symptoms: a Review of Causes, Effects and evidence-Based Treatment, J Reprod Med. 2005 Mar;50(3):155-65. | [Regarding non-pharmacological interventions]: “Although anecdotal reports have suggested that some of these strategies may provide relief, few patients seem to benefit from these interventions.”[Regarding SSRIs]: “the utility of these drugs is restricted by frequent side effects.”[Regarding alternative medicine]: “…no better, or slightly more effective, than placebo.” |
| Ansbacher R. The Pharmacokinetics and Efficacy of Different Estrogens are Not Equivalent. Am J Obstet Gynecol. 2001 Feb;184(3):255-63 | “Generic conjugated estrogens have been manufactured; however, the therapeutic equivalence of these generic products to CEE cannot be ensured…” |
| No author listed. Generic and Therapeutic Substitution. National Pharmacy Compliance News 2000;4th quarter:2-3. | ‘“I've seen quite a bit of confusion regarding the substitutability of certain drugs, most recently between Premarin (conjugated estrogen tablets, USP) and Cenestin (synthetic conjugated estrogens, A),” says Ronald Maddox, Dean of the Campbell University School of Pharmacy. “The FDA determined that these two drugs are not therapeutically equivalent and, therefore, has not listed the products with a therapeutic equivalence code.”‘ |

| Mosca L. Hormone Replacement Therapy in the Prevention and Treatment of Atherosclerosis.Curr Atherosclerosis Reports 2000 Jul;2(4):297-302. | “Remarkable consistency among epidemiologic studies supports a cardioprotective role of ERT.”“The biologic evidence for a role of estrogen to prevent CVD is compelling. Concerns regarding potential adverse effects among susceptible women and the lack of confirmatory data from randomized trials make general recommendation [sic] difficult to make.” |
| Rackley CE. New clinical markers predictive of cardiovascular disease: the role of inflammatory mediators. Cardiol Rev. 2004;12(3):151-7. | “The use of HT was associated with higher baseline levels of CRP but no change in IL-6 in either the case or the control group. However, the use of HT was less important than the actual baseline values of CRP and IL-6 in predicting cardiovascular risk.” |
| Koh KK. Can a Healthy Endothelium Influence the Cardiovascular Effects of Hormone Replacement Therapy? Int J Cardiol. 2003;87(1):1-8. | “… the HERS trial had certain methodological pitfalls, including insufficient statistical power, a high crossover rate between treatment arms, and other medications effect. Second, the early increment in coronary event rates might have been precipitated by procoagulant effects of HRT and a susceptible cohort… The controversy occasioned by the HERS trial can be resolved only through sufficiently powered, randomized controlled trials.” |

| Lobo R, Whitehead M. Is Low-Dose Hormone Replacement Therapy for Postmenopausal Women Efficacious and Desirable?Climacteric. 2001 Jun;4(2):110-9. | “The potential for fewer side-effects with low-dose formulations may play an important role in enhancing patient acceptance and continuance of ERT/HRT. Lower doses may also reduce patients’ concerns about cancer.” |
| Maddox RW. The Efficacy and Safety of Low-dose Hormone Therapy. US Pharmacist 2004 (June). | “The recent approval by the FDA of the new oral LD [low-dose]-ET/HT formulations… represents an important advance in menopausal management and osteoporosis prevention. The dosage of ethinyl estradiol in low-dose oral contraceptives is… four to seven times greater than that in SD [standard-dose]-HT, or six to 14 times greater than that in LD-ET/HT.” |

Relationship between planned messages and final text in the supplement Postmenopausal Hormone Therapy and Breast Health: A Review for Clinicians.
| Article | Planned Messages | Excerpts From Published Article |
| Speroff L. | “Recent studies suggest the possibility of a slightly increased risk of breast cancer associated with long-term use of postmenopausal hormone therapy”“However, the results from the many epidemiologic studies on this relationship are not consistent or uniform, and taken together, fail to provide definitive evidence of causality”“Discussion of results of recent studies, pointing out strengths and weaknesses, as well as both null and positive findings of a relationship between HRT and breast cancer detection”“Mortality data, detection bias, more treatable tumors” | “…more than half of the studies conducted in the past 25 years found either no difference in risk or a decreased risk of breast cancer with ERT/HRT use.”“…if there is an increased risk of breast cancer associated with the use of ERT/HRT, this risk must be small.”“These recent studies continue the pattern of inconsistency in research on this topic…”“Even studies that detect an increased risk of breast cancer in hormone users suggest, paradoxically, a better outcome.”“In the absence of results from large, randomized clinical trials, clinicians can help patients to understand that current research findings on breast cancer risk and long-term use of ERT/HRT are inconclusive, no studies find an increased risk with short-term use, and women who use postmenopausal hormones have lower mortality rates.” |
| DiSaia PJ. | “Rationale for estrogen use in breast cancer survivors (esp., number of women)”“Review evidence from naturally-occurring situations with estrogen exposure and breast cancer (pregnancy during or after breast cancer, HRT use, OC use)”“Use of estrogen by women who have had breast cancer does not appear to increase risk of recurrence” | “Numerous studies have reported better survival rates for women using HRT at the time of breast cancer diagnosis compared with those for nonusers.”“Observational studies suggest that postmenopausal hormone therapy after breast cancer diagnosis does not negatively affect breast cancer recurrence or survival.”“Breast cancer prognosis is not negatively affected by exposure to increased estrogen levels during or after pregnancy or by exposure to exogenous estrogens around the time of diagnosis.”“… exposure to estrogen around the time of breast cancer diagnosis and the use of ERT/HRT in breast cancer survivors do not negatively impact patient outcomes.” |
| Commonly Asked Questions About Postmenopausal Hormone Therapy and Breast Health [Originally Patient Education Handout] | “Inform patients that many studies do not show an increased risk”“give clear information about how many more women will get breast cancer if reported risk are [sic] accurate”“compare risk of breast cancer from postmenopausal hormone therapy with everyday risks”“emphasize significant health risks for postmenopausal women (cardiovascular diseases)”“Connect HRT to OCs and the comfort level that many women have with OCs” | “Close to 60 research studies have compared breast cancer risk in women who use HRT and in women who do not. Most of these studies found no increased risk of breast cancer with HRT use.”“Researchers have consistently found no increase in breast cancer risk with short-term use of HRT. Studies on long-term use, however, have reported conflicting results, which means that more studies are needed.”“Researchers have consistently found that HRT use does not increase breast cancer risk in women with a family history of breast cancer.”“However, there is no evidence that HRT use affects breast cancer detection.”“Studies have found that breast cancer patients using HRT at the time they were diagnosed tend to have smaller tumors that are less aggressive and are detected at a more favorable stage than are tumors of nonusers.”“…estrogen and progesterone, are the same hormones found in birth control pills, only at much lower doses (less than 1/10th the dose).”“Use of HRT also protects bone health and may decrease a woman's risk of developing colon cancer, Alzheimer's disease, heart disease, and macular degeneration (a condition associated with aging that may cause loss of vision).” |
