Cardiovascular risk and bone loss in men undergoing androgen deprivation therapy for non-metastatic prostate cancer: implementation of standardized management guidelines

Addressing the risk and management of cardiometabolic complications in prostate cancer patients on androgen deprivation therapy and androgen receptor axis-targeted therapy: consensus statements from the Hong Kong Urological Association and the Hong Kong Society of Uro-Oncology

Background

Androgen deprivation therapy (ADT) is the foundational treatment for metastatic prostate cancer (PCa). Androgen receptor (AR) axis-targeted therapies are a new standard of care for advanced PCa. Although these agents have significantly improved patient survival, the suppression of testosterone is associated with an increased risk of cardiometabolic syndrome. This highlights the urgency of multidisciplinary efforts to address the cardiometabolic risk of anticancer treatment in men with PCa.

Methods

Two professional organizations invited five urologists, five clinical oncologists, and two cardiologists to form a consensus panel. They reviewed the relevant literature obtained by searching PubMed for the publication period from April 2013 to April 2023, to address three discussion areas: (i) baseline assessment and screening for risk factors in PCa patients before the initiation of ADT and AR axis-targeted therapies; (ii) follow-up and management of cardiometabolic complications; and (iii) selection of ADT agents among high-risk patients. The panel convened four meetings to discuss and draft consensus statements using a modified Delphi method. Each drafted statement was anonymously voted on by every panelist.

Results

The panel reached a consensus on 18 statements based on recent evidence and expert insights.

Conclusion

These consensus statements serve as a practical recommendation for clinicians in Hong Kong, and possibly the Asia-Pacific region, in the management of cardiometabolic toxicities of ADT or AR axis-targeted therapies in men with PCa.

A review focusing on the role of pyroptosis in prostate cancer

As one of the types of programmed cell death, pyroptosis has become a focus of research in recent years. Numerous studies have shown that pyroptosis plays a regulatory role in tumor cell invasiveness, differentiation, proliferation, and metastasis. It has been demonstrated that pyroptosis is involved in the regulation of signaling pathways implicated in the pathogenesis of prostate cancer (PCa). Furthermore, the loss of expression of pyroptosis-related genes in PCa has been reported, and pyroptosis-related genes have demonstrated a considerable ability in predicting the prognosis of PCa. Therefore, the potential role of pyroptosis in regulating the development of PCa warrants further investigation and attention. In this review, we summarize the basics of the role of pyroptosis and also discuss research into the mechanisms of action associated with pyroptosis in PCa. It is hoped that by exploring the potential of the pyroptosis pathway in intervening in PCa, it will provide a viable direction for the diversification of PCa treatment.

A review of the objective cognitive function measurements in males receiving hormonal therapy for prostate cancer

PURPOSE

Prostate cancer (PC) is more common in the older population and the use of hormonal therapy in PC can increase medical frailty and cognitive decline. This narrative review examines the impact of androgen deprivation therapies (ADTs) and next-generational hormonal therapies (NGHT) on cognitive function outcomes amongst patients with hormone-sensitive or castrate-resistant PC.

MATERIALS AND METHODS

Six electronic databases were searched from January 2000 to June 2022 for quantitative studies to evaluate the impacts of hormonal therapies (ADT, combined androgen blockade, and NGHT) on cognitive functions in men with PC.

RESULTS

Of the 36 studies identified, 20 studies reported no effect of hormonal therapies on any cognitive domain while 16 studies found possible declines in at least one domain. The domains assessed were highly variable and objective assessment measurements were not standardized or widely adopted. While the results have been inconsistent, a relationship between declining androgen levels and poorer performances in the visuospatial and visual memory domains has been highlighted. It was not possible to distinguish the degree of cognitive parameter changes between the populations of hormone-sensitive and castrate-resistant PC.

CONCLUSIONS

While the exact impact of ADT and NGHT on cognitive function in men with PC remains controversial, appropriate care should be undertaken especially in older and frail individuals, specifically in those with progressive or established visuospatial or visual memory deficits.

The role of ferroptosis in prostate cancer: a novel therapeutic strategy

The incidence of prostate cancer is the second most among male cancers after lung cancer. Prostate cancer develops rapidly and is inclined to metastasize, and castration-resistant prostate cancer (CRPC) can be formed in the later stage, which brings great challenges to the prognosis and treatment. At present, the main treatment of prostate cancer is generally divided into four methods: surgery, chemotherapy, radiotherapy and endocrine therapy. However, the efficacy of these methods fails to satisfy the demands of patient prognosis. Ferroptosis is a newly discovered iron-dependent process, characterized by lipid peroxidation. Ferroptosis is associated with many diseases, especially tumor growth. In recent years, inhibiting tumor growth and overcoming tumor drug resistance by inducing ferroptosis has become a hot research topic. Previous studies have shown that induction of ferroptosis may be a new treatment for prostate cancer. We review the research progress of ferroptosis in prostate cancer in order to provide highly effective therapies for patients with prostate cancer.

The Burden of Uncontrolled Cardiovascular Risk Factors in Men With Prostate Cancer: A RADICAL-PC Analysis

Background

Cardiovascular disease (CVD) incidence is higher in men with prostate cancer (PC) than without.

Objectives

We describe the rate and correlates of poor cardiovascular risk factor control among men with PC.

Methods

We prospectively characterized 2,811 consecutive men (mean age 68 ± 8 years) with PC from 24 sites in Canada, Israel, Brazil, and Australia. We defined poor overall risk factor control as ≥3 of the following: suboptimal low-density lipoprotein cholesterol (>2 mmol/L if Framingham Risk Score [FRS] ≥15 and ≥3.5 mmol/L if FRS <15), current smoker, physical inactivity (<600 MET min/wk), suboptimal blood pressure (BP) (≥140/90 mm Hg if no other risk factors, systolic BP ≥120 mm Hg if known CVD or FRS ≥15, and ≥130/80 mm Hg if diabetic), and waist:hip ratio >0.9.

Results

Among participants (9% with metastatic PC and 23% with pre-existing CVD), 99% had ≥1 uncontrolled cardiovascular risk factor, and 51% had poor overall risk factor control. Not taking a statin (odds ratio [OR]: 2.55; 95% CI: 2.00-3.26), physical frailty (OR: 2.37; 95% CI: 1.51-3.71), need for BP drugs (OR: 2.36; 95% CI: 1.84-3.03), and age (OR per 10-year increase: 1.34; 95% CI: 1.14-1.59) were associated with poor overall risk factor control after adjustment for education, PC characteristics, androgen deprivation therapy, depression, and Eastern Cooperative Oncology Group functional status.

Conclusions

Poor control of modifiable cardiovascular risk factors is common in men with PC, highlighting the large gap in care and the need for improved interventions to optimize cardiovascular risk management in this population.

How to Improve the Quality of Life of Patients with Prostate Cancer Treated with Hormone Therapy?

Prostate cancer (PC) is a hormone-sensitive tumor. Androgen deprivation therapy (ADT) is the cornerstone of systemic therapy for patients with intermediate or high-risk localized, recurrent, and metastatic prostate cancer. Although generally well tolerated, ADT can lead to short- and long-term adverse events that can worsen the quality of life of patients with PC. In the last decade, the introduction of novel generation androgen receptor pathway inhibitors (ARPI) has resulted in an improvement in the prognosis of patients with metastatic PC when used in combination with ADT. The use of ARPI in increasingly early stages of the disease determines a longer exposure of patients to these treatments. Although ARPIs are normally well-tolerated drugs, they generally cause an increase in toxicity compared to ADT alone, being able to worsen some adverse events already induced by ADT or leading to the development of specific side effects. Although there are no specific treatments for all the adverse events induced by hormonal therapies, it is essential to know the possible toxicities induced by the different treatments and to start procedures to prevent and/or recognize and consequently treat them early in order to not compromise the quality of life of the patients with PC. The aim of this review is to describe the adverse events induced by hormonal therapies. We will first describe the side effects induced by both ADT and ARPI and then the specific adverse events of the different ARPIs. Furthermore, we will try to highlight the possible therapeutic options to prevent or mitigate the toxicity induced by hormone therapies in order to improve the quality of life of the patients with PC.

Ponicidin Treatment Improved the Cell Proliferation, Differentiation, and Calcium Mineralization on the Osteoblast-Like MG-63 Cells

Osteoporosis is a general bone-related ailment characterized by reduced bone density and quality, elevated bone fragility, and fractures. It was reported that both aged men and women has an increased risks of osteoporosis. The current research work focused to unveil the beneficial roles of ponicidin treatment in the proliferation and calcium deposition on the osteoblast-like MG-63 cells. The effect of 5 and 10 µg/ml of ponicidin on the cell proliferation was assessed. The viability of ponicidin-supplemented MG-63 cells was inspected by MTT test. The contents of osteocalcin, collagen, and ALP activity in the ponicidin administered cells were assessed by kits. The level of calcium mineralization was examined by ARS staining technique. The ponicidin treatment remarkably improved the proliferation of MG-63 cells. The ponicidin did not affect the MG-63 cells viability but promoted its viability 24- and 48-h treatment. The contents of osteocalcin, collagen, and ALP activity in the 5 and 10 µg/ml of ponicidin-supplemented MG-63 cells were found increased than the control cells. The ponicidin also increased the level of calcium deposition in MG-63 cells, which is assessed by ARS staining. In conclusion, it was clear that ponicidin improved the proliferation and calcium mineralization in a MG-63 cells. Therefore, it was clear that ponicidin has helpful roles on the new bone development as a hopeful therapeutic candidate to treat the bone-related disease like osteoporosis.

A New Old Target: Androgen Receptor Signaling and Advanced Prostate Cancer

Owing to the development of multiple novel therapies, there has been major progress in the treatment of advanced prostate cancer over the last two decades; however, the disease remains invariably fatal. Androgens and the androgen receptor (AR) play a critical role in prostate carcinogenesis, and targeting the AR signaling axis with abiraterone, enzalutamide, darolutamide, and apalutamide has improved outcomes for men with this lethal disease. Targeting the AR and elucidating mechanisms of resistance to these agents remains central to drug development efforts. This review provides an overview of the evolution and current approaches for targeting the AR in advanced prostate cancer. It describes the biology of AR signaling, explores AR-targeting resistance mechanisms, and discusses future perspectives and promising novel therapeutic strategies. Expected final online publication date for the Annual Review of Pharmacology and Toxicology, Volume 62 is January 2022.

Models of care for osteoporosis: A systematic scoping review of efficacy and implementation characteristics

BACKGROUND

Osteoporosis affects over half of adults over 50 years worldwide. With an ageing population, osteoporosis, fractures and their associated costs are increasing. Unfortunately, despite effective therapies, many with osteoporosis remain undiagnosed and untreated. Models of care (MoC) to improve outcomes include fracture liaison services, screening, education, and exercise programs, however efficacy for these is mixed. The aim of this study is to summarise MoC in osteoporosis and describe implementation characteristics and evidence for improving outcomes.

METHODS

This systematic scoping review identified articles via Ovid Medline and Embase, published in English between 01/01/2009 and 15/06/2021, describing MoC for adults aged ≥18 years with, or at risk of, osteoporosis and / or health professionals caring for this group. All included at least one of clinical, consumer or clinician outcomes, with fractures and bone mineral density (BMD) change the primary clinical outcomes. Exclusion criteria were studies assessing pharmaceuticals or procedures without other interventions, or insufficient operational details. All study designs were included, with no comparator necessary. Title and abstract were reviewed by two reviewers. Full text review and data extraction was performed by these reviewers for 20% of article and, thereafter by a single author. As the review was predominantly descriptive, no comparator statistics were used.

FINDINGS

314 articles were identified describing 289 MoC with fracture liaison services (n=89) and education programs (n=86) predominating. The population had prior fragility fracture in 77 studies, the median (IQR) patient number was 210 (87, 667) and the median (IQR) follow-up duration for outcome assessment was 12 (6, 12·5) months. Fracture reduction was reported by 65 studies, with 16 (37%) graded as high quality, and 19 / 47 studies with a comparator group found a reduction in fractures. BMD change was reported by 73 studies, with 41 finding improved BMD. Implementation characteristics including reach, fidelity and loss to follow-up were under-reported, and consumer and clinician perspectives rare.

INTERPRETATION

This comprehensive review of MoC for osteoporosis demonstrated inconsistent evidence for improving outcomes despite similar types of models. Future studies should include implementation outcomes, consumer and clinician perspectives, and fracture or BMD outcomes with sufficient duration of follow-up. Authors should consider pragmatic trial designs and co-design with clinicians and consumers.

A multidisciplinary team-based approach with lifestyle modification and symptom management to address the impact of androgen deprivation therapy in prostate cancer: A randomized phase II study

BACKGROUND

Androgen deprivation therapy (ADT) is associated with numerous toxicities that are potentially modifiable. We sought to evaluate the impact of participation in a multidisciplinary clinic, STAND (Supportive Therapy in Androgen Deprivation) Clinic, designed to provide individualized lifestyle modification and management of ADT-related side effects.

METHODS

This phase II study recruited men with prostate cancer who had started ADT <6 months prior to enrollment, and in whom ADT was planned for at least 12 months following enrollment. Patients were randomized in a 1:1 ratio to either the STAND Clinic or usual care. Patients randomized to the STAND Clinic were provided monthly multidisciplinary assessment and counseling on exercise, nutrition, and symptom management for 12 months on a rotating schedule. Primary outcome was change from baseline to 12 months in percent body fat. Feasibility outcomes were also assessed by measuring percentage of completed visits. Secondary outcomes included change from baseline to 12 months in 3 domains: (1) metabolic impact and bone health, (2) quality of life (QOL), and (3) physical activity.

RESULTS

A total of 25 men were randomized to STAND clinic, and 23 were randomized to usual care. The study did not meet its accrual target of 32 men in each arm and was closed early due to lack of financial support. Overall, 91% (295 of 325) of STAND clinic visits were completed. Eighteen out of the 25 patients in STAND clinic arm (72%) completed all 12 months of STAND clinic visits, and 80% (20 of 25) completed the first 6 months. For all primary and secondary outcomes, there were no statistically significant differences between treatment arms.

CONCLUSION

Individualized and comprehensive management of ADT toxicities in a multidisciplinary clinic was well attended by patients. However, we did not find any differences in the outcomes assessed between the intervention arm and control.

Androgen Deprivation Therapy in Pedophilic Disorder: Exploring the Physical, Psychological, and Sexual Effects From a Patient's Perspective

BACKGROUND

The use of androgen deprivation therapy (ADT) shows promising results in the treatment of paraphilic disorders. Although the side effects of ADT can be intrusive, there is no research into the experiences of patients with pedophilic disorder themselves.

AIM

This research aims to explore the psychological, physical, and sexual experiences of ADT from the perspective of sex offenders diagnosed with pedophilic disorder.

METHODS

Twelve semistructured in-depth interviews with male adults diagnosed with pedophilic disorder were conducted using a phenomenological approach. Six of the 12 respondents were on luteinizing hormone-releasing hormone agonists and the remaining on anti-androgens. Half of each group were inpatients, and the other half outpatients. The respondents were recruited in collaboration with one psychiatric hospital. The data were analyzed with help of a qualitative software application NVivo.

OUTCOMES

The respondents described experiences on the use of ADT on a physical, psychological, and sexual level.

RESULTS

The most prominent physical side effects mentioned were bone loss, weight gain, and breast formation. The respondents generally described a positive influence of the medication on their well-being. They felt more relaxed and experienced a reduction in frequency and intensity of sexual fantasies, anger, and aggressive feelings in general. In addition, all the respondents noticed a lower frequency of sexual contact and masturbation. Most of the participants experienced the use of ADT as a mandatory decision made by the treating psychiatrist.

CLINICAL IMPLICATIONS

This study recommends informing patients and their loved ones on the potential side effects of ADT. Furthermore, training forensic counselors on potential side effects of ADT and methods to alleviate them can promote the dissemination of information and will encourage the informed consent procedure.

STRENGTHS & LIMITATIONS

This is the first qualitative study about the experiences of ADT in men diagnosed with pedophilic disorder in Belgium. Future studies should include more than one treatment center.

CONCLUSION

The majority of the participants had a positive attitude towards ADT in general. Boons L, Jeandarme I, Vervaeke G. Androgen Deprivation Therapy in Pedophilic Disorder: Exploring the Physical, Psychological, and Sexual Effects From a Patient's Perspective. J Sex Med 2021;18:353-362.

Zoledronic acid does not affect insulin resistance in men receiving androgen deprivation therapy: a prespecified secondary analysis of a randomised controlled trial

BACKGROUND

Animal studies suggest that undercarboxylated osteocalcin may improve insulin sensitivity via its effect on testicular testosterone production. Human studies have been conflicting. Men undergoing androgen deprivation therapy (ADT) for prostate cancer experience profound hypogonadism resulting in increased insulin resistance. In a randomised controlled trial (RCT) of zoledronic acid versus placebo in men commencing extended-duration ADT, we aimed to examine the effects on fat mass and glucose metabolism. We hypothesised that zoledronic acid, which reduces osteocalcin concentrations, would worsen ADT-induced insulin resistance.

METHODS

This was a prespecified secondary analysis of an RCT designed to evaluate the effects of zoledronic acid on bone microarchitecture in 76 men with non-metastatic prostate cancer undergoing curative radiotherapy combined with adjuvant ADT (n = 39 randomised to a single dose of zoledronic acid 5 mg, n = 37 randomised to matching placebo). Oral glucose tolerance tests to determine Matsuda Index were performed at 0, 3, 12 and 24 months. Using a mixed model, mean adjusted differences [MAD (95% confidence interval)] between the groups over time are reported.

RESULTS

Over 24 months of ADT, fat mass increased and lean mass decreased for both groups, with no significant between group difference [MAD 401 g (-1307; 2103), p = 0.23 and -184 g (-1325; 955), p = 0.36 respectively]. Bone remodelling markers C-telopeptide [MAD -176 ng/l (-275; -76), p < 0.001 and P1NP -18 mg/l (-32; -5), p < 0.001] as a surrogate for osteocalcin, remained significantly lower in the zoledronic acid group, compared with placebo. There was no mean adjusted between-group difference for homeostatic model assessment 2 insulin resistance (HOMA2-IR) [-0.2 (-0.6; 0.2), p = 0.45], HbA1c [-0.1% (-0.3; 0.1), p = 0.64] or Matsuda Index [0.8 (-1.1; 2.7), p = 0.38]. The Matsuda Index decreased in both groups consistent with worsening insulin resistance with ADT.

CONCLUSION

A single dose of zoledronic acid does not appear to influence glucose metabolism in men newly commencing ADT. Further study to evaluate the endocrine relationship between bisphosphonates, bone and glucose metabolism is required.

Androgen deprivation therapy and side effects: are GnRH antagonists safer?

Androgen deprivation therapy (ADT) with gonadotropin-releasing hormone (GnRH) agonists and antagonists is the mainstay of advanced prostate cancer treatment. Both drug classes decrease levels of luteinizing hormone and follicle-stimulating hormones (FSH), thereby lowering testosterone to castrate levels. This is associated with adverse events (AEs), including cardiovascular (CV) disorders, bone fractures, metabolic dysfunction, and impaired cognitive function. This literature review discusses these AEs, with a focus on CV and bone-related events. A hypothesis-generating meta-analysis of six clinical trials showed a potentially increased risk for CV disorders with GnRH agonists versus the GnRH antagonist degarelix. While no study has directly compared GnRH agonists versus antagonists with a primary CV outcome, one hypothesis for this observation is that GnRH agonists lead to initial surges in FSH that may negatively impact CV health, whereas antagonists do not. GnRH agonists are associated with metabolic and cognitive AEs and while data are lacking for GnRH antagonists, no differences in risk are predicted. Other common AEs with ADT include injection site reactions, which are much more common with degarelix than with GnRH agonists, which may reflect differing administration and injection techniques. Future studies are needed to further evaluate and compare the safety profiles of GnRH agonists and antagonists, especially in patients with pre-existing CV disease and other co-morbidities. Physicians should carefully evaluate benefits and risks when prescribing ADT and ensure that side effects are well managed.

Differing Effects of Zoledronic Acid on Bone Microarchitecture and Bone Mineral Density in Men Receiving Androgen Deprivation Therapy: A Randomized Controlled Trial

Androgen deprivation therapy (ADT) given to men with prostate cancer causes rapid and severe sex steroid deficiency, leading to increased bone remodeling and accelerated bone loss. To examine the effects of a single dose of zoledronic acid on bone microarchitecture, we conducted a 2-year randomized placebo controlled trial in 76 men, mean age (interquartile range [IQR]) 67.8 years (63.8 to 73.9) with non-metastatic prostate cancer commencing adjuvant ADT; 39 were randomized to zoledronic acid and 37 to matching placebo. Bone microarchitecture was measured using high-resolution peripheral quantitative computed tomography (HR-pQCT). Using a mixed model, mean adjusted differences (MAD; 95% confidence interval [95% CI]) between the groups are reported as the treatment effect at several time points. Over 24 months, zoledronic acid showed no appreciable treatment effect on the primary outcomes for total volumetric bone mineral density (vBMD); radius (6.7 mg HA/cm³ [-2.0 to 15.4], p = 0.21) and tibia (1.9 mg HA/cm³ [-3.3 to 7.0], p = 0.87). Similarly, there were no between-group differences in other measures of microarchitecture, with the exception of a modest effect of zoledronic acid over placebo in total cortical vBMD at the radius over 12 months (17.3 mgHA/cm³ [5.1 to 29.5]). In contrast, zoledronic acid showed a treatment effect over 24 months on areal bone mineral density (aBMD) by dual-energy X-ray absorptiometry (DXA) at all sites, including lumbar spine (0.10 g/cm² [0.07 to 0.13]), p < 0.001), and total hip (0.04 g/cm² [0.03 to 0.05], p < 0.001). Bone remodeling markers were initially suppressed in the treatment group then increased but remained lower relative to placebo (MADs at 24 months CTX -176 ng/L [-275 to -76], p < 0.001; P1NP -18 mg/L [-32 to -5], p < 0.001). These findings suggest that a single dose of zoledronic acid over 2 years is ineffective in preventing the unbalanced bone remodeling and severe microstructural deterioration associated with ADT therapy. © 2020 American Society for Bone and Mineral Research.

Pathophysiology of Bone Loss in Patients with Prostate Cancer Receiving Androgen-Deprivation Therapy and Lifestyle Modifications for the Management of Bone Health: A Comprehensive Review

Androgen-deprivation therapy (ADT) is a systemic therapy administered for the management of advanced prostate cancer (PCa). Although ADT may improve survival, long-term use reduces bone mass density (BMD), posing an increased risk of fracture. Considering the long natural history of PCa, it is essential to preserve bone health and quality-of-life in patients on long-term ADT. As an alternative to pharmacological interventions targeted at preserving BMD, current evidence recommends lifestyle modifications, including individualized exercise and nutritional interventions. Exercise interventions include resistance training, aerobic exercise, and weight-bearing impact exercise, and have shown efficacy in preserving BMD. At the same time, it is important to take into account that PCa is a progressive and debilitating disease in which a substantial proportion of patients on long-term ADT are older individuals who harbor axial bone metastases. Smoking cessation and limited alcohol consumption are commonly recommended lifestyle measures in patients receiving ADT. Contemporary guidelines regarding lifestyle modifications vary by country, organization, and expert opinion. This comprehensive review will provide an evidence-based, updated summary of lifestyle interventions that could be implemented to preserve bone health and maintain quality-of-life throughout the disease course of PCa.

Metabolic Alterations, Aggressive Hormone-Naïve Prostate Cancer and Cardiovascular Disease: A Complex Relationship

Background: Epidemiological studies suggest a possible relationship between metabolic alterations, cardiovascular disease and aggressive prostate cancer, however, no clear consensus has been reached. Objective: The aim of the study was to analyze the recent literature and summarize our experience on the association between metabolic disorders, aggressive hormone-naïve prostate cancer and cardiovascular disease. Method: We identified relevant papers by searching in electronic databases such as Scopus, Life Science Journals, and Index Medicus/Medline. Moreover, we showed our experience on the reciprocal relationship between metabolic alterations and aggressive prostate cancer, without the influence of hormone therapy, as well the role of coronary and carotid vasculopathy in advanced prostate carcinoma. Results: Prostate cancer cells have an altered metabolic homeostatic control linked to an increased aggressivity and cancer mortality. The absence of discrimination of risk factors as obesity, systemic arterial hypertension, diabetes mellitus, dyslipidemia and inaccurate selection of vascular diseases as coronary and carotid damage at initial diagnosis of prostate cancer could explain the opposite results in the literature. Systemic inflammation and oxidative stress associated with metabolic alterations and cardiovascular disease can also contribute to prostate cancer progression and increased tumor aggressivity. Conclusions: Metabolic alterations and cardiovascular disease influence aggressive and metastatic prostate cancer. Therefore, a careful evaluation of obesity, diabetes mellitus, dyslipidemia, systemic arterial hypertension, together with a careful evaluation of cardiovascular status, in particular coronary and carotid vascular disease, should be carried out after an initial diagnosis of prostatic carcinoma.

The current state of reproductive biology research in Australia and New Zealand: core themes from the Society for Reproductive Biology Annual Meeting, 2016

Because reproduction is essential for all life, it is central to our understanding of all aspects of biology. The Society for Reproductive Biology (SRB) 2016 conference held on the Gold Coast (Qld, Australia) displayed the current breadth of reproductive research in Australia and New Zealand, with additional insights from world leaders in the field. This conference review provides a focused summary of the key questions, emerging ideas and novel technologies that were presented in the symposia. Presented research demonstrated key advances in how stem cell biology may allow us to better understand pluripotency, as well as how environmental and lifestyle factors, such as circadian disruption, smoking, alcohol and diet, affect gametogenesis, embryo implantation, placental function and reproductive capacity. Sessions also highlighted the role of reproductive biology in providing insight into the mechanisms and processes governing a wide range of biological science disciplines, including cancer research and therapies, oncofertility, conservation of native species and chronic non-communicable diseases. Recurring themes included the importance of male and female gamete quality for reproductive potential and the critical and varied roles of the placenta in the maintenance of a healthy pregnancy. Dysregulation of reproductive processes can contribute to a variety of pathological states that affect future health, fertility and fecundity. Research being conducted by the SRB has the potential to shape not only the fertility of the current generation, but also the health and reproductive viability of future generations.

Persisting adverse body composition changes 2 years after cessation of androgen deprivation therapy for localised prostate cancer

OBJECTIVE

Hypogonadism from androgen deprivation therapy (ADT) for prostate cancer causes adverse body composition changes associated with insulin resistance and decreased quality of life (QoL). Our objective was to assess whether adverse body composition changes improve after cessation of ADT.

DESIGN

Prospective case-control study in a tertiary referral hospital. Thirty-four men newly commencing ADT (cases, median age: 67.6 years (interquartile range: 64.6-72.0)) and 29 age-matched (70.6 years (65.3-72.9)) prostate cancer controls not on ADT were assessed 2 years after cessation of ADT (median: 4.4 years).

METHODS

Serum testosterone, body composition, handgrip strength, frailty and QoL were measured. Using a mixed model, the mean adjusted differences (MADs (95% CI)) between groups from baseline to study end are reported.

RESULTS

Twenty-seven cases and 19 controls completed the study. Median duration of ADT was 2.3 years (interquartile range: 1.8-3.1). Two years after cessation of ADT, total testosterone remained lower (MAD: -3.4 nmol/L (-6.3 to -0.5), P < 0.022), fat mass (2214 g (490-3933), P = 0.025) and insulin resistance (homeostasis model assessment of insulin resistance: 0.69 (0.31-1.07), P < 0.001) remained higher in cases, whereas lean mass (-1450 g (-2259 to -640), P < 0.001) and physical component of QoL remained lower than controls (-11.9 (-16.4 to -7.4), P < 0.001).

CONCLUSION

Two years after ADT cessation, metabolically adverse changes in body composition, increased insulin resistance and reduced QoL persisted. This may be related to incomplete testosterone recovery. Persisting adverse effects need to be considered in the risk to benefit assessment of ADT and proactive mitigation should continue after cessation of treatment.

Efficacy of a multi-component exercise programme and nutritional supplementation on musculoskeletal health in men treated with androgen deprivation therapy for prostate cancer (IMPACT): study protocol of a randomised controlled trial

Background

Prostate cancer is the most commonly diagnosed cancer in men in developed countries. Androgen deprivation therapy (ADT) is a systemic treatment shown to increase survival in selected patients with prostate cancer. The use of ADT continues to increase for all stages and grades of prostate cancer despite known treatment-induced adverse effects. The primary aim of this study is to examine the efficacy of a targeted, multi-component resistance and impact-loading exercise programme together with a daily protein-, calcium- and vitamin D-enriched supplement on bone health in men treated with ADT for prostate cancer. Secondary aims are to determine the effects of this intervention on measures of total body and regional body composition, cardiometabolic risk, inflammatory markers, health-related quality of life and cognitive function.

Methods

This study is a two-arm randomised controlled trial. Men currently treated with ADT for prostate cancer will be randomised to either a 52-week, community-based, exercise training and nutritional supplementation intervention (n = 51) or usual care control (n = 51). Participants will be assessed at baseline, 26 weeks and 52 weeks for all measures. The primary outcome measures are proximal femur and lumbar spine areal bone mineral density (BMD). Secondary outcomes comprise: changes in tibial and radial bone structure and strength, total body and regional body composition, muscle strength and function, as well as cardiometabolic health, catabolic/inflammatory and anabolic/anti-inflammatory cytokines, health-related quality of life and cognitive function.

Discussion

This study investigates whether a multi-component intervention incorporating a targeted bone and muscle-loading programme in combination with a protein-, calcium- and vitamin D-enriched supplement can ameliorate multiple adverse effects of ADT when compared to usual care. The results will contribute to the development of exercise training and nutrition guidelines for optimising overall health in men treated with ADT for prostate cancer.

Cardiovascular Complications of Androgen Deprivation Therapy for Prostate Cancer

OPINION STATEMENT

Prostate cancer is a common hormone-sensitive malignancy, and androgen deprivation therapy (ADT) is a cornerstone of therapy in advanced disease. The most important and controversial of ADT side effects is cardiovascular (CV) toxicity. Prospective trials have demonstrated that ADT increases CV risk by lowering insulin sensitivity, causing dyslipidemia, and causing weight gain thus mimicking metabolic syndrome. Retrospective data suggests that ADT increases CV risk; however, data on cardiovascular mortality is equivocal. This discrepancy can be explained by study design limitations and selection bias inherent to post hoc analysis of trials not designed to study CV outcomes. Despite the adverse CV and metabolic sequelae of ADT, little data is available for optimal cardiac screening or management in these patients. The short-term CV risk is higher in patients who have had CV events in the year prior to starting ADT. A careful discussion of risk and benefit of ADT must take place with patients with pre-existing CV disease prior to initiating hormonal therapy. The duration of ADT must be considered. We recommend diligent pretherapy screening and optimization of cardiac risk factors and close surveillance especially within the first year of ADT.

Somatic mutations in salivary duct carcinoma and potential therapeutic targets

Background

Salivary duct carcinomas (SDCa) are rare highly aggressive malignancies. Most patients die from distant metastatic disease within three years of diagnosis. There are limited therapeutic options for disseminated disease.

Results

11 cases showed androgen receptor expression and 6 cases showed HER2 amplification. 6 Somatic mutations with additional available targeted therapies were identified: EGFR (p.G721A: Gefitinib), PDGFRA (p.H845Y: Imatinib and Crenolanib), PIK3CA (p.H1047R: Everolimus), ERBB2 (p.V842I: Lapatinib), HRAS (p.Q61R: Selumetinib) and KIT (p.T670I: Sorafenib). Furthermore, alterations in PTEN, PIK3CA and HRAS that alter response to androgen deprivation therapy and HER2 inhibition were also seen.

Materials and Methods

Somatic mutation analysis was performed on DNA extracted from 15 archival cases of SDCa using the targeted Illumina TruSeq Amplicon Cancer Panel. Potential targetable genetic alterations were identified using extensive literature and international somatic mutation database (COSMIC, KEGG) search. Immunohistochemistry for androgen receptor and immunohistochemistry and fluorescent in situ hybridization for HER2 were also performed.

Conclusions

SDCa show multiple somatic mutations, some that are amenable to pharmacologic manipulation and others that confer resistance to treatments currently under investigation. These findings emphasize the need to develop testing and treatment strategies for SDCa.

Lifestyle guidelines for managing adverse effects on bone health and body composition in men treated with androgen deprivation therapy for prostate cancer: an update

Background:

Men treated with androgen deprivation therapy (ADT) for prostate cancer are prone to multiple treatment-induced adverse effects, particularly with regard to a deterioration in bone health and altered body composition including decreased lean tissue mass and increased fat mass. These alterations may partially explain the marked increased risk in osteoporosis, falls, fracture and cardiometabolic risk that has been observed in this population.

Methods:

A review was conducted that assessed standard clinical guidelines for the management of ADT-induced adverse effects on bone health and body composition in men with prostate cancer.

Results:

Currently, standard clinical guidelines exist for the management of various bone and metabolic ADT-induced adverse effects in men with prostate cancer. However, an evaluation of the effectiveness of these guidelines into routine practice revealed that men continued to experience increased central adiposity, and, unless pharmacotherapy was instituted, accelerated bone loss and worsening glycaemia occurred.

Conclusions:

This review discusses the current guidelines and some of the limitations, and proposes new recommendations based on emerging evidence regarding the efficacy of lifestyle interventions, particularly with regard to exercise and nutritional factors, to manage ADT-related adverse effects on bone health and body composition in men with prostate cancer.

Practice Patterns Compared with Evidence-based Strategies for the Management of Androgen Deprivation Therapy-Induced Side Effects in Prostate Cancer Patients: Results of a European Web-based Survey

BACKGROUND

Evidence-based recommendations are available for the management of androgen deprivation therapy (ADT)-induced side effects; however, there are no data on the implementation of the recommendations into daily practice patterns.

OBJECTIVE

To compare practice patterns in the management of ADT-induced side effects with evidence-based strategies.

DESIGN, SETTING, AND PARTICIPANTS

A European Web-based survey was conducted from January 16, 2015, to June 24, 2015. The 25-item questionnaire was designed with the aid of expert opinion and covered general respondent information, ADT preference per disease stage, patient communication on ADT-induced side effects, and strategies to mitigate side effects. All questions referred to patients with long-term ADT use. Reported practice patterns were compared with available evidence-based strategies.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

Following data collection, descriptive statistics were used for analysis. Frequency distributions were compiled and compared using a generalised chi-square test.

RESULTS AND LIMITATIONS

In total, 489 eligible respondents completed the survey. Luteinising hormone-releasing hormone-agonist with or without an antiandrogen was the preferred method of ADT in different settings. Patients were well informed about loss of libido (90%), hot flushes (85%), fatigue (67%), and osteoporosis (63%). An osteoporotic and metabolic risk assessment prior to commencing ADT was done by one-quarter of physicians. The majority (85%) took preventive measures and applied at least one evidence-based strategy. Exercise was recommended by three-quarters of physicians who advocate its positive effects; however, only 25% of physicians had access to exercise programmes. Although the minimum sample size was set at 400 participants, the current survey remains susceptible to volunteer and nonresponder bias.

CONCLUSIONS

Patients were well informed about several ADT-induced complications but uncommonly underwent an osteoporotic and metabolic risk assessment. Nevertheless, physicians partially provided evidence-based strategies for the management of the complications. Physicians often advised exercise to reduce ADT-induced side effects, but programmes were not widely available.

PATIENT SUMMARY

Implementation of evidence-based strategies for androgen deprivation therapy-induced side effects in real-life practice patterns should be improved.

Prevalence of osteoporosis in prostate cancer survivors II: a meta-analysis of men not on androgen deprivation therapy

The prevalence of osteoporosis in men with prostate cancer (PCa) on androgen deprivation therapy (ADT) is well documented, with up to 53% affected by this bone condition. However, there has been less emphasis on the burden of severe bone loss in men with PCa but not undergoing ADT. Therefore, the purpose of this meta-analysis is to compile evidence from the literature on the bone health of hormone-naïve PCa patients and to compare it to the bone health of men with PCa on ADT. Three databases were searched for the relevant literature published from 1990 until January 2014. The pooled prevalence of osteoporosis, low bone mass, and normal bone mass were estimated for this patient group and compared with similar subgroups from a previously published meta-analysis. The prevalence of osteoporosis varies from 4 to 38% in hormone-naïve PCa patients, and men with more advanced disease have a higher prevalence of osteoporosis. Men with PCa on ADT have poorer bone health than their hormone-naïve counterparts, but the trend toward poorer bone health with metastatic disease remains. In conclusion, it was found that men with PCa experience poor bone health prior to treatment with ADT. These results suggest that all men with PCa should have regular bone health monitoring, whether they commence ADT or not, in order to prevent or indeed minimize the morbidity that accompanies osteoporosis.

[Prostate cancer treated with androgen deprivation therapy: Care and monitoring in daily practice]

OBJECTIVE

Our purpose was to identify measures implemented by urologists and radiation oncologists at the initiation of a 6-month formulation of luteinizing hormone releasing hormone (LHRH) agonist in patients with advanced PCa.

MATERIAL

This cross-sectional cohort survey was conducted during 6 months. Participants completed a questionnaire of 15 items on the first prescription of an androgen deprivation therapy (ADT), the parameters prescribed for monitoring and information provided to patients.

RESULTS

The median age of the 1100 enrolled patients was 75 years (range: 51-98 years); 245 patients (29.0%) were metastatic and 411 (39.4%) had a Gleason score ≥ 8. Prior to the treatment initiation, the dosage of the total testosterone was not very often performed (4.8%). Associated comorbidities such as arterial hypertension (53.6%) and hypercholesterolemia (31.8%) did not constitute a barrier to the initiation of ADT, alone (60.5%) or combined with anti-androgens (61%). According to the recommendations of the French Association of Urology (AFU), fasting glycemia was required in 427 patients (41.1%), lipid profile in 380 (36.1%), a blood count in 219 (21.1%) and bone densitometry in 111 (10.8%). The advice given to patients involved diet and lifestyle rules (61%). The potential risks of adverse events (AEs) mentioned were mainly hot flashes (95.5%).

CONCLUSION

Some recommendations seem insufficiently followed by the French specialists on information and monitoring procedures of ADT, especially in the cardiovascular field.

Androgen-deprivation therapy and bone loss in prostate cancer patients: a clinical review

Androgen-deprivation therapy (ADT) has become a standard of care in the management of advanced prostate cancer or as an adjunct therapy. However, ADT is associated with a well-known deleterious effect on bone health, resulting in a decrease in bone-mass density (BMD) and increased risk for fracture. With the longer life expectancy of prostate cancer patients, improvement of the quality of life has become increasingly important. Therefore, adequate screening, prevention and treatment of BMD loss is paramount. Zoledronic acid and denosumab have shown promising results in recent studies, which has led to the Food and Drug Administration approval of these treatment options in various settings throughout the course of the disease, including the prevention of ADT-associated bone loss. This review focuses on the various parameters that impact BMD loss in men initiating ADT, on the specific effect of ADT on bone health and on various lifestyle modifications and treatment options such as bisphosphonates, osteoclast-targeted therapy and selective estrogen-receptor modulators that have shown promising results in recent studies.

The effects of 6-gingerol on proliferation, differentiation, and maturation of osteoblast-like MG-63 cells

We investigated whether 6-gingerol affects the maturation and proliferation of osteoblast-like MG63 cells in vitro. Osteoblast-like MG63 cells were treated with 6-gingerol under control conditions, and experimental inflammation was induced by tumor necrosis factor-α (TNF-α). Expression of different osteogenic markers and cytokines was analyzed by real-time PCR, Western blotting, and enzyme-linked immunosorbent assay. In addition, alkaline phosphatase (ALP) enzyme activity and biomineralization as markers for differentiation were measured. Treatment with 6-gingerol resulted in insignificant effects on the proliferation rate. 6-Gingerol induced the differentiation of osteoblast-like cells with increased transcription levels of osteogenic markers, upregulated ALP enzyme activity, and enhanced mineralized nodule formation. Stimulation with TNF-α led to enhanced interleukin-6 and nuclear factor-κB expression and downregulated markers of osteoblastic differentiation. 6-Gingerol reduced the degree of inflammation in TNF-α-treated MG-63 cells. In conclusion, 6-gingerol stimulated osteoblast differentiation in normal physiological and inflammatory settings, and therefore, 6-gingerol represents a promising agent for treating osteoporosis or bone inflammation.

Cessation of Primary Androgen Deprivation Therapy for Men With Localized Prostate Cancer

INTRODUCTION

Substantial numbers of men with localized prostate cancer undergo long-term primary androgen deprivation therapy (ADT). Whether long-term ADT is required for patients with localized prostate cancer, especially elderly men, remains unknown. In the present study, we explored the possibility of ADT cessation after a favorable response to primary ADT in patients with localized prostate cancer.

PATIENTS AND METHODS

We retrospectively reviewed men with localized prostate cancer who had achieved a good initial response to primary ADT and stopped it thereafter. Prostate-specific antigen (PSA) recurrence was defined as 2 consecutive increases > 4 ng/mL. A total of 34 patients (age, 62-89 years) were followed up for > 24 months after ADT cessation.

RESULTS

The ADT duration and follow-up period after ADT cessation was 10 to 162 months (median, 33.5 months) and 24 to 95 months (median, 37 months), respectively. PSA recurrence was observed in 10 of 34 patients (29.4%), and the 5-year PSA progression-free rate was 66.2%. PSA recurrence was observed in 100% (6 of 6) and 14.3% (4 of 28) of men who had received ADT for < 16 months and > 16 months, respectively. ADT was reinstated in 5 patients after PSA recurrence; and their PSA levels declined rapidly, and no clinical progression was observed. The 5-year overall and disease-specific survival rate was 65.1% and 100%, respectively.

CONCLUSION

ADT can be stopped for men with localized prostate cancer, especially elderly men, after a favorable response to primary ADT.

Current topics in testosterone replacement of hypogonadal men

All forms of hypogonadism - primary, secondary and late-onset - require testosterone substitution. The indication is given when the patient presents with symptoms of androgen deficiency and the serum testosterone levels are below normal. Several testosterone preparations and modes of application are available of which those producing physiologic serum levels should be preferred e.g. preferentially transdermal gels and long-acting intramuscular testosterone undecanoate. Testosterone substitution must be monitored at regular intervals, best at 3, 6 and 12 months after initiation and then annually. Parameters for surveillance include well-being, libido and sexual activity, measurement of serum testosterone levels, haemoglobin and haematocrit, PSA and digital rectal examination, and, biannually, bone mineral density. Testosterone has positive effects on comorbidities such as obesity, metabolic syndrome, diabetes type II, cardiovascular diseases and osteoporosis.

Quantifying observational evidence for risk of fatal and nonfatal cardiovascular disease following androgen deprivation therapy for prostate cancer: a meta-analysis

CONTEXT

Whether androgen deprivation therapy (ADT) for men with prostate cancer (PCa) increases the risk of cardiovascular disease (CVD) remains controversial. Pooled analyses using data from randomised controlled trials suggest no increased risk of fatal CVD following ADT, but no pooled analyses exist for observational studies.

OBJECTIVE

To perform a meta-analysis using observational data on ADT and risk of CVD events in men with PCa.

EVIDENCE ACQUISITION

PubMed and Embase were searched using predefined inclusion criteria to perform meta-analyses on associations between types of ADT and nonfatal and fatal CVD outcomes using information from observational studies. Random effects meta-analyses were conducted to estimate relative risks (RRs) and 95% confidence intervals (CIs).

EVIDENCE SYNTHESIS

A total of eight observational studies were identified studying at least one type of ADT and a nonfatal or fatal CVD outcome. The RR for risk of any type of nonfatal CVD was 1.38 (95% CI, 1.29-1.48) for men with PCa on gonadotropin-releasing hormone (GnRH) agonists, compared with men not treated with ADT. When analysing nonfatal ischemic heart disease only, the RR was 1.39 (95% CI, 1.26-1.54). The associations between GnRH agonists and nonfatal or fatal myocardial infarction or stroke were even stronger: RR: 1.57 (95% CI, 1.26-1.94) and RR: 1.51 (95% CI, 1.24-1.84), respectively. The results for other types of ADT in relation to the risk of any nonfatal CVD were RR: 1.44 (95% CI, 1.28-1.62) for orchiectomy and RR: 1.21 (95% CI, 1.07-1.367) for antiandrogens.

CONCLUSIONS

Observational data show a consistent positive association between ADT and the risk of CVD. This finding supports the need for future randomised trials of PCa patients that include older patients and men with multiple comorbidities to better reflect the general population.

PATIENT SUMMARY

We investigated all the available data from observational studies on hormonal treatment for prostate cancer and its possible cardiovascular adverse effects. We found consistent evidence that this treatment may increase the risk of cardiovascular disease.

Functional and metabolic complications of androgen deprivation therapy

Prostate cancer is the most common non-cutaneous cancer in men worldwide. Several different treatment strategies are available including minimally invasive procedures for localized tumors such as radical prostatectomy, radiotherapy, and androgen deprivation therapy, among others. All these strategies can be given as mono-therapy or as combination therapy. For this review, we will focus on the side effects of androgen deprivation therapy, independent of the other treatment modalities. Some of the most common affections are loss of bone mineral density, weight gain and obesity, myocardial infarction and sudden death, metabolic syndrome and insulin resistance, dyslipidemia, loss of libido and erectile dysfunction, fatigue, cognitive decline, vasomotor flushing, to mention a few. All these alterations can have an impact on quality of life and even lead to more serious complications such as fractures and cardiovascular complications. We present recommendations for prevention, early recognition and treatment. The different modalities for androgen deprivation therapy have particular side-effects profiles and indications should be made in an individualized manner. Androgen deprivation therapy is a useful tool for some patients with prostate cancer but every effort should be made to avoid related complications. The use of guidelines and educational programs for both, patients and urologists, are extremely useful strategies.

Muscle and bone effects of androgen deprivation therapy: current and emerging therapies

Prostate cancer and treatment with androgen deprivation therapy (ADT) affect significant numbers of the male population. Endocrine effects of ADT are a critical consideration in balancing the benefits and risks of treatment on long-term survival and quality of life. This review highlights the latest advances in androgen manipulation in prostate cancer with an emphasis on the effects of ADT on muscle and bone, which universally affects the health and well-being of men undergoing ADT for prostate cancer. Muscle mass declines with ADT; however, the evidence that this correlates with a decrease in muscle strength or a decrease in physical performance is discordant. Cortical bone decay also occurs in association with an increase in fracture risk, hence optimization of musculoskeletal health in men undergoing ADT is crucial. The role of exercise, and current and emerging anabolic therapies for muscle as well as various new strategies to prevent loss of bone mass in men undergoing ADT are discussed. Future well-designed, prospective, controlled studies are required to elucidate the effects of ADT on physical performance, which are currently lacking, and larger randomized controlled trials are required to test the efficacy of medical therapies and exercise interventions to target proven deficits and to ensure safety in men with prostate cancer.

German medical students' interest in and knowledge about human sexuality in 1972 and 2012

INTRODUCTION

During the 1970s, a growing number of medical schools began to recognize the importance of medical education concerning human sexuality. Currently, most medical schools provide at least some instruction in human sexuality.

AIM

In light of this development, the present study aimed to compare the interest in and knowledge about human sexuality of medical students from two different time periods.

METHODS

The answers to a self-constructed questionnaire of 236 students in 1972 were compared with those of 259 students in 2012. Students were asked whether they were interested in education regarding human sexuality and which specific topics they felt should be included in the medical curriculum. The students' knowledge in the following domains was assessed: sexual development, sexual behavior, sexual physiology and psychology, and sexual medicine.

MAIN OUTCOME MEASURES

The two cohorts were compared with regard to those specific sexuality-related topics in which the students were most and least interested in. Furthermore, the number of correct responses to the knowledge questions was compared.

RESULTS

While in 1972, 99.2% of the students were interested in medical education about human sexuality, in 2012, 80.3% showed an interest. The connection of disorders from different medical disciplines with sexuality was rated as most interesting by both the students from 1972 and 2012. Medical students from 2012 gave 50.3% correct answers to the knowledge questions, whereas students from 1972 correctly answered 46.3% of the questions.

CONCLUSIONS

Although interest in education concerning human sexuality has decreased, the majority of students view it as an important topic. Nevertheless, medical students still lack knowledge about important aspects of human sexuality (e.g., psychosexual development and relative safety of different contraceptives). Therefore, more time should be dedicated to education concerning human sexuality and its cultural, societal, and health aspects in particular.

Androgens and prostate cancer; pathogenesis and deprivation therapy

Although androgen receptor signaling is critical for prostate cancer growth and survival, evidence supporting a favorable risk-benefit ratio of androgen deprivation therapy (ADT) is currently limited to men with high-risk or metastatic disease. This is in part because ADT has been associated with a number of constitutional and somatic side effects, consistent with the widespread tissue expression of sex steroid receptors. ADT is the most common contemporary cause of severe hypogonadism, and men receiving this therapy represent a unique model of severe sex steroid deficiency with a defined time of onset. This review will present an update on the role of ADT in the treatment of prostate cancer, will summarize recent evidence regarding ADT-associated adverse effects with particular emphasis on cardiometabolic and musculoskeletal health, and will provide recommendations for further research.
