Men with locally advanced prostate cancer face a high risk of disease progression and cancer-related death. The traditional active treatment options for locally advanced disease, either following failure of treatment of primary curative intent or newly diagnosed, are radiotherapy and castration. Radiotherapy alone has a high failure rate, although outcome can be improved by adjuvant hormonal therapy. Castration is associated with loss of libido, sexual dysfunction, osteoporosis and hot flushes, which are significant drawbacks when patients may receive treatment for several years. Monotherapy with a non-steroidal antiandrogen offers potential benefits with respect to quality of life. Studies in the adjuvant setting are in progress. In the setting of previously untreated locally advanced disease, pooled mature data (56% deaths) from two major studies indicate no significant difference in survival outcome between bicalutamide ('Casodex') 150 mg and castration. Bicalutamide 150 mg offers quality of life benefits with respect to sexual interest and physical capacity. Preliminary data suggest that bicalutamide maintains bone mineral density. Bicalutamide 150 mg is well tolerated; gynaecomastia and breast pain, common side effects of antiandrogen monotherapy, may be managed by prophylactic irradiation or surgery. Bicalutamide 150 mg monotherapy is an alternative to castration for locally advanced prostate cancer.

The purpose of this study was to ascertain whether acute menopause symptoms experienced by women with breast cancer differed from those of women experiencing a natural menopause. For the study, 200 women younger than 65 years of age receiving adjuvant systemic treatment for breast cancer were invited to complete a self-report questionnaire incorporating a previously validated tool: the Greene Climacteric Scale. The control group consisted of 200 women 50 to 64 years of age who did not have a breast cancer diagnosis. An overall response rate of 59.5% was obtained. The majority of the respondents were peri- or postmenopause at the time of the study, reporting either "irregular periods" or "no periods." Findings demonstrated that women receiving adjuvant systemic breast cancer treatment were more likely than the control group to report a current experience of menopause symptoms. Women with breast cancer also reported a higher incidence and severity of specific menopause symptoms (tiredness, hot flushes, night sweats) than control subjects. These differences remained statistically significant when controls were used for potential confounding variables such as age, menopause status, and time since last period. Hot flushes ranked second only to tiredness as side effects attributed to cancer treatments. Because of the intimate and supportive nature of their role, nurses are in a key position to conduct future research relating to women's experiences of menopause symptoms and potential therapeutic interventions. Within the specific context of breast cancer care, oncology nurses are recognized as having a central role in informing and supporting women throughout the breast cancer trajectory. Thus they are ideally placed to address menopause as a particular survivorship issue.

Estrogens have been convincingly shown to be highly effective in preventing and reversing menopause-related conditions, such as hot flushes, urogenital complaints, and postmenopausal bone loss. Observational studies report that long-term, estrogen-containing, postmenopausal hormone replacement therapy (HRT) leads to a substantial reduction in hip fractures, myocardial infarction, and possibly colonic cancer, with important consequences for health and quality of life. Estrogen replacement may postpone the onset of Alzheimer's disease and extend life. While many of these effects are biologically plausible, with a variety of cellular mechanisms being involved, only ongoing and future large-scale randomized clinical trials can and should define the effects of HRT more precisely. Long-term compliance is a key issue for long-term benefits, and offering women a choice of administration routes and regimens can only be beneficial in this respect. Pills, patches, gels, and implants are all widely prescribed. Intravaginal or intranasal forms of administration, which are very easy to use and adaptable on an individual level, are among the new options which could improve long-term continuation of HRT use. Fear of breast cancer and recurrence of vaginal bleeding are real concerns for many women considering HRT. This has led to research into lower-dose, estrogen-containing regimens, into continuous combined regimens, and into the potential of estrogen receptor alpha or beta binding molecules that may help to prevent such problems from arising. The prospects for safe and effective postmenopausal HRT with either estrogens or estrogen-like drugs are very promising when these drugs are used in a patient-tailored, risk profile-based manner.

Abrupt onset of hot flashes poses a significant problem for women treated with chemotherapy for breast cancer. Alternatives to hormone replacement, such as the use of the selective serotonin re-uptake inhibitor (SSRI) paroxetine hydrochloride, are being explored as therapies for hot flashes in this patient population. The present study investigated the efficacy of paroxetine for the treatment of hot flashes and associated symptoms in women with breast cancer. This study included 13 patients who were seen in the Psychosocial Clinic at Moffitt Cancer Center. They were referred by their medical oncologist after reporting complaints of significant difficulty with hot flashes. Baseline questionnaires were completed and a structured diagnostic interview for clinical depression was conducted, all of which were repeated 5 weeks after the paroxetine 20 mg daily was started. Significant improvements were seen in the ratings of hot flash severity (P = 0.002). In addition, significant improvements were observed in general, emotional, and mental fatigue. Rates of clinically significant depressive symptomatology also decreased and sleep quality improved significantly as well. Finally, the incidence of clinical depression improved from 39% at baseline to 8% after treatment. These preliminary data suggest that the antidepressant paroxetine can be helpful in the treatment of hot flashes and associated fatigue, sleep disturbance, and depression in women with breast cancer treated with chemotherapy. Further controlled studies are needed to more fully evaluate the efficacy of the SSRIs for hot flashes in women with breast cancer.

Selective oestrogen receptor modulators (SERMs) are compounds that interact with the oestrogen receptor and have tissue-specific effects distinct from those of oestradiol, acting as an oestrogen agonist in some tissues and as an antagonist in others. The development of SERMs that selectively interact with specific receptors, coactivators and corepressors in different organ systems offers the possibility of improving the risk:benefit profile relative to hormone replacement therapy. Tamoxifen is a SERM that acts as an oestrogen antagonist in breast tissue and is currently being used for the treatment and prevention of breast cancer. Tamoxifen also exhibits oestrogen-agonistic properties in the endometrium and increases the risk of endometrial cancer. Oestrogen and another SERM, raloxifene, have been shown to prevent osteoporosis. The effects of oestrogens on cognitive functions are currently being investigated. Recent data reveal the lack of secondary prevention of coronary heart disease with oestrogen. Oestrogen has been used to treat menopausal symptoms, whereas the SERMs have been shown to induce hot flushes. Current research is focused on producing the ideal SERM, which would have benefits over existing SERMs in terms of preventing cancer, cardiovascular disease, osteoporosis and menopausal symptoms, improving cognitive functions, and have a significantly better toxicity profile in terms of endometrial cancer and thromboembolic events.

The aims of this study were to describe a population of patients with cancer referred for complementary therapies to an NHS homeopathic hospital, and to explore the homeopathic approach to symptom control and its impact on mood disturbance and quality of life. One hundred consecutive patients attending a designated research cancer clinic were seen for a consultation, lasting up to 60 min, and prescription of a homeopathic remedy. A maximum of three symptoms were identified and rated by the patient as a problem, using a numerical self-rating scale. The effect these symptoms have on daily life and overall sense of well being were recorded using similar scales. Patients completed the Hospital Anxiety and Depression Scale (HADS) and the European Organization for Research and Treatment in Cancer--Quality of Life Questionnaire--Core 30 (EORTC QLQ-30) at the initial consultation and at four to six consultations later. After this time, the patients completed a final assessment questionnaire asking about satisfaction with the homeopathic approach, how helpful they had found the approach for the targeted symptoms and what factors they felt may have contributed to the changes perceived. One hundred patients were entered into the study. Thirty-nine patients had metastatic disease. Nine patients were refusing conventional cancer treatments. The most common symptoms were pain, fatigue and hot flushes. Symptom scores for fatigue and hot flushes improved significantly over the study period but not for pain scores. Side effects included a transient worsening of symptoms in a few cases, which settled on stopping the remedy. Fifty-two patients completed the study, and in those patients satisfaction was high, and 75% (n=38) rated the approach as helpful or very helpful for their symptoms. Results suggest that further research is warranted to explore the management of hot flushes in women with breast cancer and fatigue in the cancer diagnosis.

To evaluate the impact of tamoxifen on subjective and psychosexual well-being in breast cancer patients in relation to type of prior chemotherapy and menopausal status. Longitudinal interview study in breast cancer patients during and after adjuvant tamoxifen use. Menopausal status was defined by last menstrual period and serum oestradiol and FSH levels. Gynaecology outpatient clinic, Tertiary Referral Hospital, January 1995 to September 1999. Breast cancer patients <56 years of age, participating in a randomised trial comparing adjuvant high-dose (n=45) and standard-dose (n=53) chemotherapy, followed by radiotherapy and tamoxifen. Relative incidence and correlation of subjective and psychosexual symptoms during and after tamoxifen. During tamoxifen the most frequent complaints were hot flushes (85%), disturbed sleep (55%), vaginal dryness and/or dyspareunia (47%), decreased sexual desire (44%) and musculo-skeletal symptoms (43%). Disturbed sleep correlated with hot flushes (P<0.0005) and concentration problems (P<0.05). Decreased sexual interest correlated with vaginal dryness (P<0.0005) and/or dyspareunia (P<0.0005). In the high-dose group more patients became postmenopausal (95% vs 33%) and more patients reported symptoms than in the standard-dose group (P<0.05). After discontinuation of tamoxifen, symptoms decreased significantly. However, hot flushes, disturbed sleep and vaginal dryness persisted more often in patients who remained postmenopausal after high-dose chemotherapy (P<0.05). Overall, during tamoxifen patients reported many symptoms. More patients become postmenopausal after high-dose chemotherapy, and they remain often symptomatic after tamoxifen.

Health care professionals in modern Western societies will meet an increasing number of women surviving breast cancer. How the menopause of these women should be treated is still an open question. Use of hormone replacement therapy (HRT) may, at least in theory, increase the risk for recurrence of cancer, but its categoric refusal is a double-edged sword because it also denies these women all the undisputable health benefits HRT provides. This refusal is not, however, supported by the observational data available so far on this question, because HRT has not increased the risk for breast cancer recurrence. In fact, it is well established that HRT abolishes hot flushes and improves significantly these patients' quality of life. At present, we have no effective nonhormonal alternatives for the control of vasomotor symptoms, and the efficacy of phytoestrogens in the treatment of menopausal symptoms is unproven. Selective estrogen receptor modulators (SERMs) which protect against osteoporosis and perhaps also against breast cancer, and which may have beneficial effects on the cardiovascular system, aggravate hot flushes and are therefore not useful, at least in the first postmenopausal years. In some countries, progestins are often prescribed for the control of such patients' vasomotor symptoms, but their safety has never been assessed in clinical trials, and in theory they can be harmful. Randomized clinical trials (RCT) on the use of HRT in breast cancer survivors are underway, but their completion will take years, and even these may be open to criticism. Tibolone may appear to be an appealing alternative for HRT, but it should also be studied with RCTs in this indication. At present, a patient with a history of breast cancer must be given balanced information as to the possible benefits and risks of HRT, and she herself must make the decision whether or not to start HRT.

We present an initial survival analysis and an update of the safety data of the North American and Tamoxifen or Arimidex Randomized Group Efficacy and Tolerability (TARGET) double-blind, randomised, multicentre studies which compared anastrozole with tamoxifen as first-line treatment in postmenopausal patients with oestrogen receptor and/or progesterone receptor-positive (ER+/PR+) or receptor-unknown advanced breast cancer (ABC). At a median follow-up of 43.7 months, 56.0% of patients in the anastrozole group and 56.1% of patients in the tamoxifen group had died. The proportion of patients dead at 2 years was 31.1 and 32.0% in the anastrozole and tamoxifen groups, respectively. In the ER+/PR+ subgroup, 55.1 and 55.9% of patients had died and median time to deaths (TTD) were 40.8 and 41.3 months in the anastrozole and tamoxifen groups, respectively. Both agents remained well tolerated, with fewer reports of vaginal bleeding (anastrozole versus tamoxifen, 1.0% versus 2.5%) and thromboembolic events (anastrozole versus tamoxifen, 5.3% versus 9.0%) in the anastrozole group versus the tamoxifen group. Hot flushes and vaginal dryness were reported marginally less in the tamoxifen group compared with the Anastrozole group. Although no improvement in survival was observed, the favourable profile of anastrozole with respect to efficacy (TTP) and tolerability [Cancer 92 (2001) 2247] support the use of anastrozole in advance of tamoxifen as the first-line therapy choice in postmenopausal women with ABC.

Tamoxifen has both agonistic and antagonistic effects on the female genital tract, depending on the ambient oestradiol concentration and the menopausal status of the patient. In postmenopausal women tamoxifen has an oestrogen agonistic effect on the vaginal epithelium, the uterine myometrium and the endometrium. It may induce benign cystic hyperplasia of the endometrial stroma and cause an increase in poly formation. The risk of endometrial cancer increases 2-3-fold after an exposure of up to 5 years. In asymptomatic tamoxifen users, gynaecological surveillance is not recommended. However, if there is postmenopausal bleeding, then transvaginal ultrasonography and histology of the endometrium are indicated. Tamoxifen can aggravate hot flushes and have a negative effect on sexual function. In premenopausal women, tamoxifen may induce ovarian cysts resulting in high serum-oestradiol levels. Oligomenorrhoea and amenorrhoea will occur in half of the patients. Tamoxifen has an antagonistic effect on the endometrium in premenopausal women and is associated with hot flushes and impaired sexual functioning. Teratogenic effects on the foetus have been described. Despite its gynaecological side effects, the benefits of tamoxifen in breast-cancer treatment outweigh the risks. Patients need to be informed about these side effects. Irregular or postmenopausal blood loss must always be reported to the treating physician.
