While there are numerous uncertainties surrounding prostate cancer's detection and treatment, more research focusing on the psychological needs of prostate patients is required. This study investigated the support and psychological care needs of men with prostate cancer. Patients were approached during urological oncology clinics and asked to complete the: Support Care Needs Survey (SCNS), Support Care Preferences Questionnaire, EORTC QLQ-C30 (Version 3) Measure plus Prostate Module, and the Hospital Anxiety and Depression Scale (HADS). Of the 249 patients meeting study entry criteria, there was an 89% response rate resulting in a cohort of 210 patients. The data showed that significant unmet need exists across a number of domains in the areas of psychological and health system/information. The more commonly reported needs were 'fears about cancer spreading (44%),' 'concerns about the worries of those close to you (43%),' and 'changes in sexual feelings (41%).' Half of all patients reported some need in the domain of sexuality, especially men younger than 65 years. Needs were being well met in the domain of patient care and support. A significant number of patients reported having used or desiring support services, such as information about their illness, brochures about services and benefits for patients with cancer (55%), a series of talks by staff members about aspects of prostate cancer (44%), and one-on-one counselling (48%). Quality of life (QoL) was most negatively impacted in those who: were < or =65 years old, had been diagnosed within one year, or had metastatic disease. Men < or =65 had decreased social functioning, greater pain, increased sleep disturbance, and were more likely to be uncomfortable about being sexually intimate. Patients recently diagnosed had increased fatigue, more frequent urination, greater disturbance of sleep, and were more likely to have hot flushes. Those with advanced disease scored lower on 12 out of 15 QoL categories. PSA level had no effect on QoL or anxiety/depression scores. Men with advanced disease had greater levels of depression and those < or =65 years old were more likely to be anxious. Although most men with prostate cancer seem to function quite well, a substantial minority report areas of unmet need that may be targets for improving care.

As the number of breast cancer survivors continues to grow, factors associated with quality of life are receiving increased clinical and research attention. This attention is imperative given the aftermath of psychological and physiologic side effects that commonly result from a cancer diagnosis and cancer-related treatments, including menopausal symptoms. Hot flashes, the most prevalent of these symptoms, have been shown to significantly decrease quality of life in women. Although manageable with hormone replacement therapy (HRT), hot flashes often are especially problematic in breast cancer survivors, a population that typically is not treated with HRT because of controversial evidence of a relationship among estrogen and/or progesterone and breast cancer recurrence and mortality. Furthermore, hot flashes commonly are more severe in premenopausal women who experience acute menopause as a result of chemotherapy treatment. In recent years, several treatment alternatives to HRT have been investigated. Given the significant number of women affected by breast cancer and the negative impact that hot flashes can have on their quality of life, this article reviews alternatives to HRT for reducing hot flash symptoms in breast cancer survivors.

Idoxifene is a novel selective oestrogen receptor modulator (SERM) which had greater binding affinity for the oestrogen receptor (ER) and reduced agonist activity compared with tamoxifen in preclinical studies. In a randomized phase II trial in 56 postmenopausal patients with progressive locally advanced/metastatic breast cancer we assessed whether idoxifene showed evidence of activity compared with an increased 40 mg/day dose of tamoxifen in patients who had previously demonstrated resistance to the standard 20 mg/day dose of tamoxifen. Of 47 patients eligible for response (25 idoxifene, 22 tamoxifen), two partial responses and two disease stabilizations (SD) for >6 months were seen with idoxifene (overall clinical benefit rate 16%, 95% CI 4.5-36.1%). The median duration of clinical benefit was 9.8 months. In contrast, no objective responses were seen with the increased 40 mg/day dose of tamoxifen, although two patients had SD for 7 and 14 months (clinical benefit rate 9%, 95% CI 1.1-29.2%). Idoxifene was well tolerated and the reported possible drug-related toxicities were similar in frequency to those with tamoxifen (hot flushes 13% vs 15%, mild nausea 20% vs 15%). Endocrine and lipid analysis in both groups showed a similar significant fall in serum follicle-stimulating hormone and luteinizing hormone after 4 weeks, together with a significant rise in sex hormone binding globulin levels and 11% reduction in serum cholesterol levels. In conclusion, while idoxifene was associated with only modest evidence of clinical activity in patients with tamoxifen-resistant breast cancer, its toxicity profile and effects on endocrine/lipid parameters were similar to those of tamoxifen.

Drospirenone (DRSP) is a novel progestogen derived from 170alpha-spirolactone. Its pharmacodynamic profile is closer to progesterone than any other currently available progestogen. DRSP has progestational, antialdosterone and antiandrogenic properties, but is devoid of any estrogenic, androgenic, glucocorticoid, antiglucocorticoid or mineralocorticoid activities. The affinity of DRSP for the mineralocorticoid receptor makes it an antagonist of aldosterone, which is not only important in the renin-angiotensin-aldosterone system (RAAS), but also acts directly on the cardiovascular system. DRSP (1, 2 or 3 mg) in combination with 1 mg 17beta-estradiol (E2) is being developed by Schering AG as a continuous combined product for hormone replacement therapy (HRT). Phase II/III trials of E2/DRSP combinations have demonstrated clinical efficacy for the treatment of hot flushes, as well as improvement of bone density in the hip. Within 1 year of treatment with E2/DRSP, more than 80% of recipients regained amenorrhea. E2/DRSP at all three doses of DRSP is associated with a highly favorable safety profile, with excellent endometrial protection after 1 and 2 years (no cases of hyperplasia or cancer), favorable lipid profiles, with no evidence of attenuation of the beneficial effects on lipids of E2, probably due to DRSP's lack of androgenicity. Recipients of E2/DRSP combinations showed a small decrease in body weight, probably due to DRSP's antialdosterone properties. Adverse events with E2/DRSP did not differ significantly from those observed with standard HRT preparations. Phase III studies with E2/DRSP show that DRSP does not antagonize the well-documented reductions of blood pressure associated with E2; rather, small DRSP dose-related reductions in systolic and diastolic blood pressures were observed, which should be beneficial for recipients, especially those who are mildly hypertensive. These effects on blood pressure are probably due to DRSP displaying aldosterone receptor antagonism, a property which, in other settings, has been shown to convey benefits in terms of cardiovascular disease. Further studies of the cardiovascular effects of E2/DRSP combinations are anticipated.

Breast cancer is one of the main life-threatening diseases that a woman may have to face during her lifetime. The increasing incidence of breast neoplasia reported over the last few decades has led to widespread screening of women resulting in early diagnosis. One common but challenging question for most doctors, after the surgical excision of the lesion, is determination of the ideal adjuvant therapy for their patients for the achievement of maximum life expectancy with the best quality of life. Since the beginning of the last century, the knowledge that breast cancer arises from hormone-responsive tissues has long made use of hormone-blocking agents in the beneficial treatment of breast neoplasia. The discovery of new molecules with endocrine actions has rendered the use of adjuvant therapy in a tailor-made pattern too complicated, as these agents have a different mode of action, different adverse effects and probably different indications. The aim of the present review is to clarify these issues, analyzing the mechanism of action of available drugs and their actions on specific areas of uncertainty: cognitive function, cardiovascular system, urogenital tract, bone metabolism, weight gain, hot flushes and premature menopause. Regarding the efficacy of adjuvant therapy, there has been particular focus on the multiple hormonal-induced consequences of each regimen in order to provide the clinician with the available data for choosing the ideal therapy for the patient.

We evaluated quality of life (QL) and quality-adjusted survival in International Breast Cancer Study Group Trial IX, a randomised trial including 1669 eligible patients receiving tamoxifen for 5 years or three prior cycles of cyclophosphamide, methotrexate and 5-fluorouracil (CMF) followed by 57 months tamoxifen. During the time with CMF toxicity (Tox), without symptoms and toxicity (TWiST), and following relapse (Rel), patients scored their QL indicators and a utility indicator for subjective health estimation between 'perfect' and 'worst' health. Scores were averaged within Tox, TWiST and Rel and transformed to utilities. Mean durations for the three transition times were weighted with utilities to obtain mean quality-adjusted TWiST (Q-TWiST). Patients receiving CMF reported significantly worse scores for most QL domains at month 3, but less hot flushes. After completing chemotherapy, there were no differences by treatment groups. Benefits evaluated by Q-TWiST favoured the additional chemotherapy. CMF provided 3 more months of Q-TWiST for patients with ER-negative tumours, but CMF provided no benefit in Q-TWiST for patients with ER-positive tumours. Q-TWiST analysis based on patient ratings is feasible in large-scale cross-cultural clinical trials.

We assessed long-term side effects with characteristics of female climacteric disorders in prostate cancer patients treated with luteinizing hormone-releasing hormone (LHRH) agonists. Such side effects are not considered to be serious, though they can significantly affect patient quality of life. Sixty-four prostate cancer patients treated with LHRH agonists and 30 benign prostatic hyperplasia patients, as a control group, were surveyed by questionnaire. The median age of the cancer patients was 74.9 years old, ranging from 60 to 94 years, and the median LHRH agonist dosing period was 16.5 months, ranging from 1 to 64 months. The results of the questionnaires were compared between the patients and the controls, as well as between different variables. Sixty (93.8%) of 64 patients claimed symptoms similar to female climacteric disorders. Further, more than 50% of the symptoms included in the questionnaire were reported by 14 (21.9%) of the patients. Symptoms reported by the patients were more severe than those by the controls. Hot flashes, sleep disturbance, and fatigue recorded high scores in the patient questionnaires as compared with those of the controls. In addition, as the term of LHRH agonist use increased, complaints of sweating or coldness in hands and feet increased. Patients without bone metastasis frequently experienced heaviness in the head and headaches compared to those with bone metastasis. The results of our questionnaire-based outcome study showed that side effects similar to female climacteric disorders in prostate cancer patients treated with LHRH agonists were more severe than in the control group, which could be detrimental to quality of life and general well-being.

Hot flushes, the most common health problem reported by menopausal-age women, can lead to significant morbidity and affect the social life, ability to work and sleep pattern of the sufferer. Women treated for breast cancer and men receiving androgen ablation for prostate cancer experience hot flushes that are more frequent, severe and longer lasting than those experienced by the general menopausal population. In women with breast cancer, hot flushes can result from chemotherapy-induced menopause, hormonal therapy, or ovarian suppression. In men with prostate cancer, hot flushes occur after surgical or medical castration. Hormone replacement therapy with oestrogen-based compounds has been a mainstay of treatment for hot flushes during the perimenopausal period. However, recent studies have shown that, in healthy menopausal women, hormone replacement therapy is associated with an increased risk of breast cancer, myocardial infarction, thrombo-embolic events and stroke. Thus, identifying nonhormonal agents that can control hot-flush symptoms is essential to the quality of life of a growing population of cancer survivors. The most promising agents act on the CNS and include selective serotonin reuptake inhibitors, as well as venlafaxine and gabapentin.

Women make up 55% of the total world population. This percentage is set to steadily increase over the next three decades. Europe also has the highest proportion of older women in the world. In fact, there are now approximately 3 women for every 2 men over 65. All of this data confirms the importance of prevention. An ideal approach for the female post-menopausal population would be treatment of any condition that can improve physical, mental and social well-being. Nevertheless, it is understood that the efficacy and cost/benefits of every screening programme need to be analysed. One of the largest and most neglected groups that could benefit from prevention consists of women without hot flushes (asymptomatic women), but with risk factors. The strategic measures are information, research and development of programmes. The more practical approach would be to identify patients and therefore yield better results in terms of health status and improvement. Statistics show that the three main causes of mortality and disability in developed countries for post-menopausal women are cardiovascular disease (CVD), cancer and osteoporosis-associated fractures. There are agreed recommendations to include some preventive measures for these three disorders in clinical practice for health professionals, at least at the minimal level. Research into the role that other diseases play will allow strategies to be developed in order to enhance prevention. Disorders such as urinary incontinence, dyspareunia, visual and hearing impairment and cognitive dysfunction are seen in significant percentages in post-menopausal women and may affect their quality of life. Health care professionals should bear in mind that many women may be reluctant to raise questions about some disorders spontaneously. Physicians should therefore search for patients with risk factors for these diseases. Prevention and treatment to avoid medical accidents will improve the quantity and quality of life.

Prostate cancer represents the most common noncutaneous malignancy in men. With the widespread use of prostate-specific antigen screening, as many as one in six men in the USA will be diagnosed with prostate cancer. Significant healthcare resources are currently devoted to the treatment of this disease, specifically aimed at improving the side effects of successful treatment. Surgery or radiation therapy provides the best chance of cure from this disease. However, as many as 50% of patients treated with curative intent will develop a recurrence 10-15 years following treatment. Hormonal ablation via medical or surgical castration provides disease control, but is associated with significant hot flushes, loss of libido and impotence. Selective, apoptotic antineoplastic drugs, such as exisulind, may provide an alternative method to treating or preventing prostate cancer. This drug profile reviews the evidence for the use of exisulind in the treatment of prostate cancer.
