Zung's Self-Rating Anxiety Scale and Self-Rating Depression Scale were used to collect data from 195 Australian men who had received a diagnosis of prostate cancer. Analysis was via separate scales and also by combining both scales into a single unit to assess anxiety-depression and then analysing the underlying component structure of that unit. Applying Zung's recommended cutoff scores, 12% of the sample were classified as having clinically significant levels of anxiety and 16% had similar levels of depression. Factor analysis of the combined SAS and SDS indicated four major components which reflected a process of: loss of functional capacity, worthlessness and hopelessness, fear and somatic symptomatology. Implications for the effective assessment and treatment of anxiety and depression in prostate patients are discussed.

The androgen receptor mediates the androgenic and anabolic activity of the endogenous steroids testosterone and 5alpha-dihydrotestosterone. Current knowledge of the androgen receptor protein structure, and the molecular mechanisms surrounding the binding properties and activities of agonists and antagonists has led to the design and development of novel nonsteroidal ligands with selected tissue-specific androgen receptor agonist and antagonist activities. The activity of these compounds, termed selective androgen receptor modulators (SARMs), is directed toward the maintenance or enhancement of anabolic effects on bone and muscle with minimal androgenic effects on prostate growth. SARMs are of potential therapeutic value in the treatment of male hypogonadism, osteoporosis, frailty and muscle wasting, burn injury and would healing, anemia, mood and depression, benign prostatic hyperplasia and prostate cancer.

African American men experience worse prostate cancer outcomes compared with those of Caucasian men, not only in incidence and mortality rates, but also in coping with the side effects of treatment. Unfortunately, African American men have been significantly under-represented in research evaluating the efficacy of psychosocial interventions for improving coping in prostate cancer survivors. This pilot study explored the feasibility and efficacy of coping skills training (CST), an intervention developed to enhance coping with treatment side effects in a sample of African American prostate cancer survivors and their intimate partners. The intervention was delivered in a telephone-based format designed to facilitate research participation. A total of 40 couples were randomized to either 6 sessions of CST or usual care. Survivors completed measures of disease-specific quality of life (QOL) related to urinary, sexual, bowel, and hormonal symptom domains, as well as measures of global QOL (i.e., physical functioning and mental health). Partners completed measures of caregiver strain, mood, and vigor. Analysis of data from 30 couples (12 couples in CST, 18 couples in usual care) indicated that CST produced moderate to large treatment effects for QOL related to bowel, urinary, sexual, and hormonal symptoms. Partners who underwent CST reported less caregiver strain, depression, and fatigue, and more vigor, with moderate effect sizes observed that approached conventional levels of statistical significance. These preliminary findings suggest that telephone-based CST is a feasible approach that can successfully enhance coping inAfrican American prostate cancer survivors and their intimate partners.

While both short- and long-term androgen deprivation therapy (ADT) are effective for treating prostate cancer, with the clinical benefits patients can often have significant side-effects. It is important that these complications are recognized and managed appropriately so that adverse effects on the patient's quality of life (QoL) are minimized. The incidence of deaths from prostate cancer has decreased over the last decade, probably as a result of various factors including improved screening and diagnosis, improved treatments, and better risk assessment to help guide therapy. A meta-analysis of prostate cancer trials comparing the use of early vs late hormonal therapy found that 10-year overall survival increased by up to 20% between 1990 and 2000, and this was attributed to the earlier use of hormone therapy (HT) in these patients. Data from the USA Cancer of the Prostate Strategic Urological Research Endeavor database also suggest a significant decrease in risk in the last two decades in the USA, with more patients being identified with low-risk disease at diagnosis. In addition, there has been an increase in recent years in the use of HT at all stages of prostate cancer. The extensive use of ADT has raised concerns about potential adverse effects. ADT might be associated with a range of adverse effects that vary in their degree of morbidity and effect on the patient's QoL. They include hot flashes, osteoporosis, loss of libido or impotence, and psychological effects, e.g. depression, memory difficulties or emotional lability. Effective strategies are available for managing the major side-effects of HT, but to many patients these unwanted effects are often less important than the benefits of treatment. An investigation of health-related QoL found that men with prostate cancer receiving ADT had a poorer QoL than those not receiving ADT, but the difference was less pronounced after controlling for comorbidities. Many new therapies are currently under investigation which aim to maximize the clinical effects of ADT while reducing the adverse effects.

This article reviews the issues and controversies relevant to the treatment of advanced prostate cancer with androgen deprivation therapy. Initially, diethylstilbestrol was used for achieving androgen deprivation, but was replaced by luteinizing hormone-releasing hormone (LHRH). Adverse events associated with LHRH agonists include the flare phenomenon, hot flashes, loss of libido, erectile dysfunction, depression, muscle wasting, anemia, and osteoporosis. Intermittent therapy has been advocated to reduce morbidity of treatment. The addition of an antiandrogen provides maximum androgen blockade. There remains controversy regarding the timing of the addition of an antiandrogen. Secondary hormonal therapies include antiandrogens, adrenal androgen inhibitors, and estrogens.

Preferences for information about their disease and treatment were collected from 392 patients who had been treated for either breast or prostate cancer an average of 2 years previously. Type of information that they had received, their ratings of its value to them and their preferred format for further information were examined. The most common and most preferred form of information was through doctor interview, followed by educational booklets. Prostate cancer patients preferred videotapes; breast cancer patients tended to prefer individualized approaches including a tour of the department. Effects of age, educational levels, occupational backgrounds and self-reports for anxiety and depression at the time of the survey and at time of diagnosis were analysed. Prostate cancer patients who were most severely depressed showed a preference for not receiving any information at all, perhaps reflecting a tendency towards withdrawal.

The aim of this study was to evaluate the effect of psychosocial rehabilitation on newly diagnosed prostate cancer patients. The "Between Men" programme consisted of seven weekly sessions of physical training (Phys) alone, information (Info) alone or physical training plus information (PhysInfo). After diagnoses, patients (n = 211) were consecutively included, stratified and randomised to one of four groups: Phys, Info, PhysInfo or standard care control (C). A nurse specialised in urology, an urologist and a physiotherapist performed the interventions. Patients were followed up during one year with mailed standardised questionnaires. It could not be assumed that the "Between Men" programme had any effect on patients' anxiety and depression (HADS). Health-related quality of life (HRQOL) was associated with stage of disease but not with psychosocial intervention. Thus, Physical Function (PF), Role Function (RF) and Fatigue (FA) were inferior among patients with, than without, metastases of prostate cancer both at baseline and at the 12-month follow-up. This randomized study did not demonstrate any significant effect of psychosocial rehabilitation among prostate cancer patients. Considering the low rate (1/2), of included/eligible patients a less complicated design (intervention versus control) would have been preferred in order to increase power.

The number of men for whom testosterone is prescribed is rapidly increasing. The aging man normally demonstrates a gradual decline in testosterone. Symptoms of hypogonadism include erectile dysfunction, diminished libido, sarcopenia, increased adiposity, osteopenia and osteoporosis, impaired cognition, and depression. There is a paucity of data regarding both efficacy and safety of testosterone replacement therapy. Testosterone levels have been shown to modulate prostate cancer risk and progression. A prospective evaluation of prostate cancer risk with testosterone replacement therapy has not been conducted. We outline concerns and recommendations for the use of testosterone replacement therapy in the aging man.

The androgen receptor (AR) is a ligand-activated transcription factor which is responsible for the androgen responsiveness of target cells. Several types of mutations have been found in the AR and linked to endocrine dysfunctions. Surprisingly, the polymorphism involving the CAG triplet repeat expansion of the AR gene, coding for a polyglutamine (PolyGln) tract in the N-terminal transactivation domain of the AR protein, has been involved either in endocrine or neurological disorders. For example, among endocrine-related-diseases, the PolyGln size has been proposed to be associated to prostate cancer susceptibility, hirsutism, male infertility, cryptorchidism (in conjunction with polyglycine stretches polymorphism), etc.; the molecular mechanisms of these alterations are thought to involve a modulation of AR transcriptional competence, which inversely correlates with the PolyGln length. Among neurological alterations, a decreased AR function seems to be also involved in depression. Moreover, when the polymorphic PolyGln becomes longer than 35-40 contiguous glutamines (ARPolyGln), the ARPolyGln acquires neurotoxicity, because of an unknown gain-of-function. This mutation has been linked to a rare inherited X-linked motor neuronal disorder, the Spinal and Bulbar Muscular Atrophy, or Kennedy's disease. The disorder is characterized by death of motor neurons expressing high levels of AR. The degenerating motor neurons are mainly located in the anterior horns of the spinal cord and in the bulbar region; some neurons of the dorsal root ganglia may also be involved. Interestingly, the same type of PolyGln elongation has been found in other totally unrelated proteins responsible for different neurodegenerative diseases. A common feature of all these disorders is the formation of intracellular aggregates containing the mutated proteins; at present, but their role in the disease is largely debated. This review will discuss how the PolyGln neurotoxicity of SBMA AR may be either mediated or decreased by aggregates, and will present data on the dual role played by testosterone on motor neuronal functions and dysfunctions.

This article compares the motivations for, and responses to, castration between two groups of males: prostate cancer patients and voluntary modern-day eunuchs with castration paraphilias or other emasculating obsessions. Prostate cancer patients are distressed by the side effects of androgen deprivation and typically strive to hide or deny the effects of castration. In contrast, most voluntary eunuchs are pleased with the results of their emasculations. Despite a suggested association of androgen deprivation with depression, voluntary eunuchs appear to function well, both psychologically and socially. Motivation, rather than physiology, appears to account for these different responses to androgen deprivation.
