title: Is there a role for hormone replacement therapy after breast cancer?
abstract: 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.
