Is there a role for hormone replacement therapy after breast cancer?

Breast cancer is the most common female malignancy in the UK, with an overall lifetime risk of 1 in 9. Despite the high incidence, breast cancer mortality is decreasing. Approximately 40,000 women were diagnosed with breast cancer in England and Wales in 2000 but the majority will have normal or near-normal life expectancy. One of the main contributory factors to this marked improvement in survival over the last 20 years in women of all ages has been the more widespread use of systemic therapy in early-stage disease. For women with hormone-sensitive cancer, this involves adjuvant endocrine therapy that reduces estrogen synthesis (i.e. ovarian suppression in premenopausal women or aromatase inhibitors in postmenopausal women) or estrogen activity (the anti-estrogen tamoxifen, irrespective of menopausal status). Many women experience health and quality-of-life problems related to estrogen deficiency as a result, the commonest being vasomotor symptoms and vaginal dryness. This article summarizes and interprets key recent papers on the use of hormone replacement therapy (HRT) and selective serotonin reuptake inhibitors in breast cancer survivors. HRT may be safe in women with receptor-negative disease or receptor-positive cancers in the presence of tamoxifen. However, there is a dearth of useful alternatives.

Managing the menopause: British Menopause Society Council consensus statement on hormone replacement therapy.

The British Menopause Society Council aims to help health professionals inform and advise women about the menopause. This guidance regarding estrogen-based hormone replacement therapy (HRT), including tibolone, which is classified in the British National Formulary as HRT, responds to the results and analysis of the randomized Women's Health Initiative studies and the observational Million Women Study. Treatment choice should be based on up-to-date information and targeted to individual women's needs. HRT still offers the potential for benefit to outweigh harm, providing the appropriate regimen has been instigated in terms of dose, route and combination.

Patient and clinician collaboration in the design of a national randomized breast cancer trial.

OBJECTIVE: To show breast cancer patient involvement in the design of a national randomized trial of hormone replacement therapy (HRT) in symptomatic patients will increase accrual. SETTING AND PARTICIPANTS: Three stakeholder groups [(1) researchers from the Lynda Jackson Macmillan Centre, (2) the Consumers' Advisory Group for Clinical Trials (CAG-CT), (3) clinicians responsible for a pilot randomized HRT study in breast cancer patients] developed this collaborative study. METHODS: (1) Nine focus group discussions were conducted to identify issues relevant to breast cancer patients about HRT and a national trial: six involved women from breast cancer support groups nationwide and three patients who had previously participated in the pilot randomized HRT study. (2) Recommendations from the focus groups (analysed by Grounded Theory) were debated by the research stakeholders and focus group representatives at a 1-day meeting and consensus reached (using a voting system) on mutual priorities for incorporation into the design of a national HRT trial. (3) Representatives from the CAG-CT and focus groups participated in subsequent national HRT steering committee meetings to ensure that these priorities were accounted for and the resulting trial design summary was circulated to the CAG-CT and all focus group representatives for comment. RESULTS: Focus groups demonstrated that the complexity of factors relating to trial participation was not just restricted to the research topic in question. Patient-clinician interaction provided a platform for negotiating potential conflicts over trial design and outcomes. Patient feedback suggested that mutually agreed priorities were accounted for in the trial design. INTERPRETATION: Clinical research planning should involve all research stakeholders at the outset. Quantifying the impact of patient involvement in terms of trial accrual may be too simple given the complexity of their motivations for participating in trials.

Managing the menopause: BMS Council Consensus statement on HRT.

The British Menopause Society Council aims to help health professionals to inform and advise women about the menopause. The oestrogen plus progestogen arm of the Women's Health Initiative was stopped in July 2002. This guidance regarding hormone replacement therapy (HRT) use responds to the results and analysis that have been published since then, as well as the Million Women Study published in August 2003. Because there are few effective alternatives to HRT for vasomotor and urogenital symptoms, oestrogen-based treatments still have a major role. HRT is also most effective for the prevention of osteoporosis. Unopposed oestrogens are contraindicated in women with an intact uterus, and hence a range of oestrogen and progestogen combinations, with differing routes of delivery, now exists under the title of "HRT". Treatment choice should be based on up to date information and targeted to individual women's needs. Hormone replacement still offers the potential for benefit to outweigh harm, providing the appropriate regimen has been instigated in terms of dose, route and combination.

The menopause, hormone replacement therapy and breast cancer.

Concern exists that the reduction in breast cancer risk associated with the onset of the menopause will be negated with exposure to hormone replacement therapy (HRT). Evidence from large-scale randomised HRT trials support observational data that have shown a modest increase in breast cancer risk with long-term use (i.e. >15 years) of combined therapy, although this falls following HRT cessation suggesting a growth-promoting effect. Randomised evidence demonstrates that the efficacy of anti-estrogens, aromatase inhibitors and raloxifene in the treatment and chemoprevention of breast cancer are restricted to women with oestrogen receptor positive (ER +ve) disease; however, HRT has not been associated conclusively with a predominance of hormone sensitive breast cancer. Despite stimulating the breast cancer cell growth, HRT has not been shown to increase breast cancer recurrence or mortality when prescribed to breast cancer survivors experiencing oestrogen deficiency symptoms and randomised trials have been recommended and commenced. In conjunction with controlled breast cancer trials demonstrating a therapeutic benefit of high dose estrogens and interest in the use of additive oestrogen therapy in patients developing resistance to oestrogen deprivation, the dogma that HRT is an absolute contra-indication following diagnosis is challenged.

Hormone-replacement therapy and breast cancer.

Hormone-replacement therapy (HRT) has been available for many years, but the important question of its place in development and progression of breast cancer remains controversial; provision of reliable risk estimates has been hampered by a lack of controlled data. Observational evidence suggests that the risk of breast cancer may be increased only if HRT is used long term (ie, for longer than 10 years) and that the risk falls when use ceases. Systematic bias and the lack of adequately powered studies prevent any firm clinical recommendations about the prescription of differing HRT regimens and risk, or the effect of HRT on breast-cancer proliferation and mortality. This review aims to summarise current clinical data, justifying the need for prospective controlled trials in healthy women as well as those at higher risk of breast cancer or with a personal history of the disease.
