Andropause syndrome in men treated for metastatic prostate cancer: a qualitative study of the impact of symptoms

Men's symptom experience throughout androgen deprivation therapy for prostate cancer: A systematic review and meta-aggregation

BACKGROUND

Androgen deprivation therapy is a common treatment for men with advanced prostate cancer. They have experienced many complex symptoms that affect their quality of life. However, qualitative reviews that synthesize the symptom experience for men with prostate cancer are lacking.

OBJECTIVE

To explore the men's symptom experience throughout androgen deprivation therapy for prostate cancer.

DESIGN

A qualitative evidence synthesis using meta-aggregation.

DATA RESOURCES

Published and unpublished literature between January 2001 and August 2023 were identified from PubMed, Embase (Ovid), Web of Science, Cumulative Index to Nursing and Allied Health Literature (CINAHL), The Cochrane Library, ProQuest, Google Scholar, China National Knowledge Infrastructure (CNKI), Wang Fang, and VIP.

REVIEW METHODS

Two reviewers independently conducted screening, study selection and data extraction, and quality appraisal was performed using the Joanna Briggs Institutes Critical Appraisal Checklist for Qualitative Research. Data synthesis was conducted using meta-aggregative approach.

RESULTS

24 articles of moderate to high methodological quality were included. A total of 98 findings were extracted with 59 unequivocal or equivocal findings eligible for meta-aggregation, aggregated into nine categories, and developed four synthesized findings: (1) production of symptoms: unrecognized and underestimated, (2) perception of symptoms: varied and complicated, (3) meaning of symptoms: threatened and affected, and (4) response to symptoms: push and pull.

CONCLUSIONS

Men throughout androgen deprivation for prostate cancer experience the four crisis-packed stages in their symptomatic journey. Health care provider need to understand the men's thoughts whether in the process of shared decision-making or in the course of the chosen therapy. Future research should develop individual suitable interventions and offer practical strategies for managing symptom. PROSPERO registration: CRD42023449129.

The Experiences of Female Partners of Patients With Erectile Dysfunction Due to Prostate Cancer Treatment in China: A Qualitative Exploration

BACKGROUND

Because of sociocultural factors, Chinese female partners of patients with prostate cancer (PC) may have perspectives and needs that differ from the more published reports of female partners living in Western cultures.

OBJECTIVES

The aim of this study was to explore the experiences of female partners of patients with PC experiencing erectile dysfunction in China.

INTERVENTIONS/METHODS

In this interpretive descriptive design, qualitative data were collected from semistructured telephone interviews with purposively sampled participants from the urology outpatient unit in a hospital in South China. The interviews were audiotaped, transcribed, and analyzed using a constant comparison approach.

RESULTS

Three themes emerged from the analysis of the participants' narratives: (a) acceptance of ceasing sex; (b) preserving intimacy through caregiving; and (c) the need for sexual health-related information.

CONCLUSION

Participants in this study reported that their own sexuality and intimacy were affected by their partner's erectile dysfunction, but they adjusted to sexuality and intimacy changes through their caregiving of their husbands owing to Chinese traditional perspectives on women's obligations. They also reported having unmet informational needs in improving sexual well-being for the sake of their partners, lending further support to the likely benefit of couple-based educational interventions addressing sexual wellness in dyads affected by PC and erectile dysfunction.

IMPLICATIONS FOR PRACTICE

The present study findings highlighted the need for more research attention to the support of Chinese female partners of patients with PC regarding sexual and intimate topics.

Patient and General Population Preferences Regarding the Benefits and Harms of Treatment for Metastatic Prostate Cancer: A Discrete Choice Experiment

Background

Patient preferences for treatment outcomes are important to guide decision-making in clinical practice, but little is known about the preferences of patients with metastatic hormone-sensitive prostate cancer (mHSPC).

Objective

To evaluate patient preferences regarding the attributed benefits and harms of systemic treatments for mHSPC and preference heterogeneity between individuals and specific subgroups.

Design setting and participants

We conducted an online discrete choice experiment (DCE) preference survey among 77 patients with metastatic prostate cancer (mPC) and 311 men from the general population in Switzerland between November 2021 and August 2022.

Outcome measurements and statistical analysis

We evaluated preferences and preference heterogeneity related to survival benefits and treatment-related adverse effects using mixed multinomial logit models and estimated the maximum survival time participants were willing to trade to avert specific adverse effects. We further assessed characteristics associated with different preference patterns via subgroup and latent class analyses.

Results and limitations

Patients with mPC showed an overall stronger preference for survival benefits in comparison to men from the general population (p = 0.004), with substantial preference heterogeneity between individuals within the two samples (both p < 0.001). There was no evidence of differences in preferences for men aged 45-65 yr versus ≥65 yr, patients with mPC in different disease stages or with different adverse effect experiences, or general population participants with and without experiences with cancer. Latent class analyses suggested the presence of two groups strongly preferring either survival or the absence of adverse effects, with no specific characteristic clearly associated with belonging to either group. Potential biases due to participant selection, cognitive burden, and hypothetical choice scenarios may limit the study results.

Conclusions

Given the relevant heterogeneity in participant preferences regarding the benefits and harms of treatment for mHSPC, patient preferences should be explicitly discussed during decision-making in clinical practice and reflected in clinical practice guidelines and regulatory assessment regarding treatment for mHSPC.

Patient summary

We examined the preferences (values and perceptions) of patients and men from the general population regarding the benefits and harms of treatment for metastatic prostate cancer. There were large differences between men in how they balanced the expected survival benefits and potential adverse effects. While some men strongly valued survival, others more strongly valued the absence of adverse effects. Therefore, it is important to discuss patient preferences in clinical practice.

Psychosocial Aspects of Living Long Term with Advanced Cancer and Ongoing Systemic Treatment: A Scoping Review

(1) Background: Studies examining the psychosocial impact of living long term on systemic treatment in advanced cancer patients are scarce. This scoping review aimed to answer the research question “What has been reported about psychosocial factors among patients living with advanced cancer receiving life-long systemic treatment?”, by synthesizing psychosocial data, and evaluating the terminology used to address these patients; (2) Methods: This scoping review was conducted following the five stages of the framework of Arksey and O’Malley (2005); (3) Results: 141 articles published between 2000 and 2021 (69% after 2015) were included. A large variety of terms referring to the patient group was observed. Synthesizing qualitative studies identified ongoing uncertainty, anxiety and fear of disease progression or death, hope in treatment results and new treatment options, loss in several aspects of life, and worries about the impact of disease on loved ones and changes in social life to be prominent psychosocial themes. Of 82 quantitative studies included in the review, 76% examined quality of life, 46% fear of disease progression or death, 26% distress or depression, and 4% hope, while few studies reported on adaptation or cognitive aspects. No quantitative studies focused on uncertainty, loss, or social impact; (4) Conclusion and clinical implications: Prominent psychosocial themes reported in qualitative studies were not included in quantitative research using specific validated questionnaires. More robust studies using quantitative research designs should be conducted to further understand these psychological constructs. Furthermore, the diversity of terminology found in the literature calls for a uniform definition to better address this specific patient group in research and in practice.

A Systematic Review of Patients' Values, Preferences, and Expectations for the Treatment of Metastatic Prostate Cancer

CONTEXT

Advances in systemic agents have increased overall survival for men diagnosed with metastatic prostate cancer. Additional cytoreductive prostate treatments and metastasis-directed therapies are under evaluation. These confer toxicity but may offer incremental survival benefits. Thus, an understanding of patients' values and treatment preferences is important for counselling, decision-making, and guideline development.

OBJECTIVE

To perform a systematic review of patients' values, preferences, and expectations regarding treatment of metastatic prostate cancer.

EVIDENCE ACQUISITION

The MEDLINE, Embase, and CINAHL databases were systematically searched for qualitative and preference elucidation studies reporting on patients' preferences for treatment of metastatic prostate cancer. Certainty of evidence was assessed using Grading of Recommendation, Assessment, Development and Evaluation (GRADE) or GRADE Confidence in the Evidence from Reviews of Qualitative Research (CERQual). The protocol was registered on PROSPERO as CRD42020201420.

EVIDENCE SYNTHESIS

A total of 1491 participants from 15 studies met the prespecified eligibility for inclusion. The study designs included were discrete choice experiments (n = 5), mixed methods (n = 3), and qualitative methods (n = 7). Disease states reported per study were: metastatic castration-resistant prostate cancer in nine studies (60.0%), metastatic hormone-sensitive prostate cancer in two studies (13.3%), and a mixed cohort in four studies (26.6%). In quantitative preference elicitation studies, patients consistently valued treatment effectiveness and delay in time to symptoms as the two top-ranked treatment attributes (low or very low certainty). Patients were willing to trade off treatment-related toxicity for potential oncological benefits (low certainty). In qualitative studies, thematic analysis revealed cancer progression and/or survival, pain, and fatigue as key components in treatment decisions (low or very low certainty). Patients continue to value oncological benefits in making decisions on treatments under qualitative assessment.

CONCLUSIONS

There is limited understanding of how patients make treatment and trade-off decisions following a diagnosis of metastatic prostate cancer. For appropriate investment in emerging cytoreductive local tumour and metastasis-directed therapies, we should seek to better understand how this cohort weighs the oncological benefits against the risks.

PATIENT SUMMARY

We looked at how men with advanced (metastatic) prostate cancer make treatment decisions. We found that little is known about patients' preferences for current and proposed new treatments. Further studies are required to understand how patients make decisions to help guide the integration of new treatments into the standard of care.

Self-care Experiences of Advanced Prostate Cancer Survivors Who Underwent Androgen Deprivation Therapy

BACKGROUND

Androgen deprivation therapy is the primary treatment for advanced cases of prostate cancer, but its adverse effects may decrease prostate cancer survivors' quality of life.

OBJECTIVE

The aim of this study was to understand the self-care experiences of prostate cancer survivors before and while receiving androgen deprivation therapy.

METHODS

A qualitative study design with inductive content analysis was used. Semistructured interviews were conducted with 13 prostate cancer survivors in Taiwan treated with androgen deprivation therapy. Data collection and analysis proceeded simultaneously until data saturation was reached.

RESULTS

The survivors' self-care experiences were categorized into generic categories: physical impacts, psychosocial impacts, lack of supporting information, changing lifestyle habits, coping with physical symptoms, relieving stress, and acquiring disease-related knowledge. These generic categories were then organized into 2 main categories: impacts and adjustments.

CONCLUSIONS

This article describes the experiences of prostate cancer survivors in terms of the impacts of disease and its treatment and adjustments in self-care before and while receiving treatment. It was found that the information acquired by survivors and the adjustment strategies they used were not entirely appropriate or adequate.

IMPLICATIONS FOR PRACTICE

Healthcare providers should continually assess the self-care experiences of prostate cancer survivors receiving androgen deprivation therapy, provide them with appropriate information, and clarify their understanding. This will improve survivors' disease care-related knowledge, increase the success of their experience of self-care, alleviate their emotional distress, and strengthen their ability to adjust their self-care to cope with the impacts of the disease and its treatment.

A qualitative exploration of South African men's perceived effects of Androgen Deprivation Therapy (ADT) as a treatment for advanced prostate cancer

OBJECTIVE

We undertake qualitative research with men treated in a Pretoria, South Africa Oncology clinic to address men's self-reported experiences on androgen deprivation therapy (ADT).

METHODS

Analyses rely upon 22 men's responses to open-ended questions during interviews. These men were 63-78 years of age, and almost all married (three widowed), had children and were no longer engaged in paid work.

RESULTS

In addressing questions about the anticipated and experienced positive and broader side effects of ADT, men referred to its treatment for prostate cancer, with several generally specifying health or life. Patients also referred to a variety of more specific effects such as pain, nausea, difficulties urinating, gaining weight, low energy and sleep disruptions that appeared to reflect a mixture of influences of prostate cancer, ADT and oncological treatment. In addressing a question about the effects of ADT on romantic/sex life, 16 of 19 married men referred to deleterious impacts on their sex lives. With respect to perceived family, work or broader social life impacts, some men noted others' worries and social support.

CONCLUSION

Findings are situated within discussions of existing research on ADT largely from North American or European samples, and broader views of testosterone and male social behavior.

Preference for sleep management strategies among prostate cancer patients: An Aotearoa/New Zealand perspective✰

INTRODUCTION

Many men with prostate cancer (PCa) experience insomnia symptoms post-treatment. We explore here PCa patients' preference for strategies to manage their sleep.

PATIENTS AND METHODS

A brief online survey was launched on Facebook and promoted by Prostate Cancer Foundation New Zealand. The survey contained validated questionnaires on various sleep-related parameters, as well as questions about sleep management strategies.

RESULTS

We recruited 82 PCa patients (67.9 ± 6.3 years old). Participants with high insomnia severity index (ISI) scores reported significantly worse daytime sleepiness, more severe fatigue, being less of a "morning person", and more frequent dreaming. Most participants (71-95%) were open to trying behavioural strategies for improving sleep hygiene, especially by improving their sleeping conditions and having a consistent sleep-wake schedule. Insomnia severity and past use of androgen deprivation therapy were significant predictors for the number of sleep treatments used. Participants with a high ISI were more likely to have used medication, CBT, and herbal remedies or supplements for treating sleep issues than those with low ISI. Furthermore, in patients who had not used these treatments options, those with a high ISI were more willing to try CBT and hypnosis compared to those with a low ISI. Reasons for not willing to try various sleep treatments were documented.

CONCLUSION

Most PCa patients are willing to adjust their behavior or lifestyle to improve their sleep habits/behaviours. Patients with severe insomnia are more likely to have both used and express willingness to try, interventions to improve sleep, with preferences for CBT and hypnosis.

Strategies for living well with hormone-responsive advanced prostate cancer-a qualitative exploration

PURPOSE

Due to recent treatment advances, men are increasingly living longer with advanced prostate cancer (PCa). This study sought to understand men's experiences of living with and adjusting to advanced hormone-responsive PCa and how this influenced their quality of life (QoL), in order to highlight how support could be optimized.

METHODS

Participants were recruited through a UK wide survey-the 'Life After Prostate Cancer Diagnosis' study. In-depth telephone interviews were conducted with 24 men (aged 46-77 years) with advanced (stage IV) hormone-responsive PCa diagnosed 18-42 months previously. Thematic analysis was undertaken using a framework approach.

RESULTS

Most participants perceived their QoL to be relatively good, which was influenced by the following factors (enablers to 'living well' with PCa): a sense of connectedness to others, engagement in meaningful activities, resources (social, cognitive, financial), ability to manage uncertainty, utilization of adjustment strategies and support, communication and information from health professionals. Barriers to 'living well' with PCa were often the converse of these factors. These also included more troublesome PCa-related symptoms and stronger perceptions of loss and restriction.

CONCLUSIONS

In our study, men living with advanced hormone-responsive PCa often reported a good QoL. Exploring the influences on QoL in men with advanced PCa indicates how future interventions might improve the QoL of men who are struggling. Further research is required to develop and test interventions that enhance QoL for these men.

Pain, fatigue and depression symptom cluster in survivors of prostate cancer

Purpose

Pain, fatigue and depression are common sequelae of a cancer diagnosis. The extent to which these occur together in prostate cancer survivors is unknown. We (i) investigated prevalence of the pain-fatigue-depression symptom cluster and (ii) identified factors associated with experiencing the symptom cluster among prostate cancer survivors.

Methods

Men in Ireland diagnosed with prostate cancer 2–18 years previously were identified from population-based cancer registries and sent postal questionnaires. Cancer-related pain and fatigue were measured using the EORTC QLQ-C30 and depression using the DASS-21. Cut-offs to define ‘caseness’ were pain ≥ 25, fatigue ≥ 39 and depression ≥ 10. Associations between survivor-related factors, clinical variables and specific prostate cancer physical symptoms and the symptom cluster were assessed using multivariate logistic regression.

Results

A total of 3348 men participated (response rate = 54%). Twenty-four percent had clinically significant pain, 19.7% had clinically significant fatigue, and 14.4% had depression; 7.3% had all three symptoms. In multivariate analysis, factors significantly associated with the symptom cluster were living in Northern Ireland, experiencing back pain at diagnosis and being affected by incontinence, loss of sexual desire, bowel problems, gynecomastia and hot flashes post-treatment. There was a strong association between the cluster and health-related quality of life.

Conclusions

The pain-fatigue-depression symptom cluster is present in 1 in 13 prostate cancer survivors. Physical after-effects of prostate cancer treatment are associated with this cluster. More attention should be paid to identifying and supporting survivors who experience multiple symptoms; this may help health-related quality of life improve among the growing population of prostate cancer survivors.

Safety of testosterone therapy in men with prostate cancer

Introduction: The use of testosterone therapy (TTh) in men with prostate cancer (PCa) is relatively new, and controversial, due to the longstanding maxim that TTh is contraindicated in men with PCa. Scientific advances have prompted a reevaluation of the potential role for TTh in men with PCa, particularly as TTh has been shown to provide important symptomatic and general health benefits to men with testosterone deficiency (TD), including many men with PCa who may expect to live 30-50 years after diagnosis. Areas covered: This review outlines the historical underpinnings of the historical belief that TTh 'fuels' PCa and the experimental and clinical studies that have radically altered this view, including description of the saturation model. The authors review studies of TTh in men with PCa following radical prostatectomy and radiation therapy, in men on active surveillance, and in men with advanced or metastatic PCa. Expert opinion: TTh provides important symptomatic and overall health benefits for men with PCa who have TD. Although more safety studies are needed, TTh is a reasonable therapeutic option for men with low-risk PCa after surgery or radiation. Data in men on active surveillance are limited, but initial reports are reassuring.

Cognitive Impacts of Estrogen Treatment in Androgen-Deprived Males: What Needs to be Resolved

Background:

Many prostate cancer (PCa) patients are on androgen deprivation therapy (ADT) as part of their cancer treatments but ADT may lead to cognitive impairments. ADT depletes men of both androgen and estrogen. Whether estradiol supplementation can improve cognitive impairments in patients on ADT is understudied.

Objective:

To summarize data on the effects of estradiol treatment on cognitive function of androgen-deprived genetic male populations (PCa patients and male-to-female transsexuals) and castrated male animals.

Method:

Publications were identified by a literature search on PubMed and Google Scholar.

Results:

While some studies showed that estradiol improves cognitive function (most notably, spatial ability) for castrated rats, what remains uninvestigated are: 1) whether estradiol can improve cognition after long-term androgen deprivation, 2) how estradiol affects memory retention, and 3) how early vs. delayed estradiol treatment after castration influences cognition. For androgen-deprived genetic males, estradiol treatment may improve some cognitive functions (e.g., verbal and visual memory), but the findings are not consistent due to large variability in the study design between studies.

Conclusion:

Future studies are required to determine the best estradiol treatment protocol to maximize cognitive benefits for androgen-deprived genetic males. Tests that assess comparable cognitive domains in human and rodents are needed. What particularly under-investigated is how the effects of estradiol on cognitive ability intersect with other parameters; sleep, depression and physical fatigue. Such studies have clinical implications to improve the quality of life for both PCa patients on ADT as well as for male-to-female transsexuals.

A qualitative metasynthesis exploring the impact of prostate cancer and its management on younger, unpartnered and gay men

Prostate cancer (PCa) can negatively impact on men's sexual, urinary and emotional functioning, affecting quality of life. Most men with PCa are older (≥65 years), married and heterosexual and little is known about the impact on men who are younger, unpartnered or gay. We aimed to synthesise existing qualitative research on these three groups of men. A systematic metasynthesis was undertaken that included data on the unique impacts of PCa on younger (<65 years) (n = 7 papers), unpartnered (n = 17 papers) or gay or bisexual men (n = 11 papers) using a modified meta-ethnographic approach. The three overarching constructs illustrated the magnified disruption to men's biographies, that included: marginalisation, isolation and stigma-relating to men's sense of being "out of sync"; the burden of emotional and embodied vulnerabilities and the assault on identity-illustrating the multiple threats to men's work, sexual and social identities; shifting into different communities of practice-such as the shift from being part of a sexually active community to celibacy. These findings suggest that PCa can have a particular impact on the quality of life of younger, unpartnered and gay men. This has implications for the provision of tailored support and information to these potentially marginalised groups.

The Effects of Social Support on Health-Related Quality of Life of Patients with Metastatic Prostate Cancer

Patients with metastatic prostate cancer (PC) live longer than patients with metastatic tumours of other sites. Consequently, their social network can influence their quality of life (QoL) during a remarkable life span. The aim of this article is to present the findings of a systematic review of the studies that focused on social network supporting the quality of life of these patients. A systematic review for studies meeting specific criteria was undertaken on three databases. Some level of unmet psychological needs was present in 54 % of the patients. Depression and fatigue are highly prevalent, and the dyads, patient and partner, are at higher risk for distress symptoms. The efforts of individuals to cope with metastatic PC appear influenced by adaptative skills and specific types of family support. Psychological and relational problems predominate in the hormone-sensitive stage and are increasingly replaced by physical symptoms, social and spiritual needs in the later stages. In the early castration-resistant stage, patients will discuss with their doctors information about drugs, control of side effects and treatment strategies. In metastatic PC patients, needs change during the course of the disease. Social support plays a major role in maintaining or disrupting QoL and in the efficacy of psychosocial treatments. The trajectory of disease and its effect on the reduced QoL over the entire life expectancy should be kept in mind by health system providers and social workers.

The Experience of Cancer Stigma in Taiwan: A Qualitative Study of Female Cancer Patients

BACKGROUND

Cancer is the leading cause of death in Taiwan. Because the causes of cancer are often difficult to identify, a diagnosis of cancer is occasionally attributed to karma and the concept of stigma. These feelings lead to a life predicament, and stigma influences these perceptions.

OBJECTIVE

This study intended to understand how stigma is formed in the disease-related experiences of women with cancer.

METHODS

Ten participants were interviewed at the time of a confirmed diagnosis of advanced cancer and completed cancer treatment with regular follow-up after treatment, and all subjects underwent 2-3 interviews. The number of interviews conducted was determined by data saturation. A content analysis method was used.

RESULTS

The stigma of cancer includes the concepts of "cancer equals death", including the feeling of death approaching and an awareness of disease severity. "Cancer equals menace to social life" suggests that social life is affected and includes other individuals' uncomfortable attitudes toward cancer (shame, sympathy, pity, suffering, and over-cautiousness) and external physical changes. "Cancer equals cancer-ridden life" includes being sensitive to the topics of death and calculating the number of remaining survival days.

CONCLUSIONS

The process from early diagnosis to the decision to receive treatment is complicated for patients with cancer. After the diagnosis is confirmed, the stigma of diagnosis significantly affects patients. Regarding social stereotypes, educating the public to resolve individuals' negative responses to cancer and further convey social and public information to women in society is necessary.

Sex differences in sleep: impact of biological sex and sex steroids

Men and women sleep differently. While much is known about the mechanisms that drive sleep, the reason for these sex differences in sleep behaviour is unknown and understudied. Historically, women and female animals are underrepresented in studies of sleep and its disorders. Nevertheless, there is a growing recognition of sex disparities in sleep and rhythm disorders. Women typically report poorer quality and more disrupted sleep across various stages of life. Findings from clinical and basic research studies strongly implicate a role for sex steroids in sleep modulation. Understanding how neuroendocrine mediators and sex differences influence sleep is central to advancing our understanding of sleep-related disorders. The investigation into sex differences and sex steroid modulation of sleep is in its infancy. Identifying the mechanisms underlying sex and gender differences in sleep will provide valuable insights leading to tailored therapeutics that benefit each sex. The goal of this review is to discuss our current understanding of how biological sex and sex steroids influence sleep behaviour from both the clinical and pre-clinical perspective.

Vasomotor symptoms in prostate cancer survivors undergoing androgen deprivation therapy

OBJECTIVE

Hot flushes and night sweats (HFNS) are common but under-researched in prostate cancer survivors undergoing androgen-deprivation therapy (ADT). We aimed to examine subjective reports and physiological measures of HFNS, and the influence of sociodemographic, clinical and psychological factors on HFNS in men undergoing ADT.

METHODS

Sixty-eight men undergoing ADT for prostate cancer attended an assessment interview, completed questionnaires (assessing HFNS frequency and problem-rating, mood, stress, optimism, somatosensory amplification, HFNS beliefs/behaviors) and wore an ambulatory sternal skin conductance (SSC) monitor for 48 h.

RESULTS

The sample had a mean age of 69.76 (standard deviation, SD = 8.04) years, were on average 27.24 (SD = 28.53) months since cancer diagnosis and had been on their current ADT regime for 16 months (range 2-74 months). The men reported frequent (weekly mean 51.04, SD = 33.21) and moderately problematic HFNS. Overall, 294 (20%) of the SSC-defined HFNS were concordant with prospective frequency (event marker), while 63% were under-reported and 17% were over-reported, under-reporting being more common than over-reporting. There were no significant predictors of HFNS frequency (subjective or physiological measures), but psychological variables (HFNS beliefs and behaviors (β = 0.56, p < 0.03), anxiety (β = 0.24, p < 0.01) and somatic amplification (β = 0.76, p < 0.04) were the main predictors of problematic HFNS, i.e. troublesome symptoms.

CONCLUSIONS

These results are consistent with those of studies of women during menopause and breast cancer survivors, i.e. subjective and physiological measures appear to identify different HFNS dimensions. Psychological variables (HFNS beliefs and behaviors, anxiety and somatic amplification) can be targeted, using cognitive behavior therapy, for symptom relief.

The perspective of prostate cancer patients and patients' partners on the psychological burden of androgen deprivation and the dyadic adjustment of prostate cancer couples

OBJECTIVE

Prostate cancer and its treatments, particularly androgen deprivation therapy (ADT), affect both patients and partners. This study assessed how prostate cancer treatment type, patient mood, and sexual function related to dyadic adjustment from patient and partner perspectives.

METHODS

Men with prostate cancer (n = 206) and partners of men with prostate cancer (n = 66) completed an online survey assessing the patients' mood (profile of mood states short form), their dyadic adjustment (dyadic adjustment scale), and sexual function (expanded prostate cancer index composite).

RESULTS

Analyses of covariance found that men on ADT reported better dyadic adjustment compared with men not on ADT. Erectile dysfunction was high for all patients, but a multivariate analysis of variance found that those on ADT experienced greater bother at loss of sexual function than patients not on ADT, suggesting that loss of libido when on ADT does not mitigate the psychological distress associated with loss of erections. In a multiple linear regression, patients' mood predicted their dyadic adjustment, such that worse mood was related to worse dyadic adjustment. However, more bother with patients' overall sexual function predicted lower relationship scores for the patients, while the patients' lack of sexual desire predicted lower dyadic adjustment for partners.

CONCLUSIONS

Both patients and partners are impacted by the prostate cancer treatment effects on patients' psychological and sexual function. Our data help clarify the way that prostate cancer treatments can affect relationships and that loss of libido on ADT does not attenuate distress about erectile dysfunction. Understanding these changes may help patients and partners maintain a co-supportive relationship. Copyright © 2015 John Wiley & Sons, Ltd. Copyright © 2015 John Wiley & Sons, Ltd.

Androgen deprivation therapy's impact on the mood of prostate cancer patients as perceived by patients and the partners of patients

OBJECTIVE

To assess the relationship between of androgen deprivation therapy (ADT) and the mood of prostate cancer (PCa) patients and partners of PCa patients.

METHODS

PCa patients (n = 295) and partners of patients (n = 84) completed an online survey assessing the patients' current mood and mood prior to treatment, relationship adjustment, and sexual function. We compared men on ADT to men who received non-hormonal treatments for their PCa.

RESULTS

Patients currently treated with ADT (n = 82) reported worsened mood as measured by the Profile of Mood States compared to those not on ADT (n = 213). The negative impact of ADT on mood, however, was reduced in older patients. Partners of patients on ADT (n = 42) reported similar declines in the patient's mood that patients reported, but to a greater degree than patient-reported levels.

CONCLUSIONS

Our data support ADT's impact on PCa patients' mood and verify that partners concurrently see the effects. The psychological changes related to ADT can impact relationships and affect the quality of life of both PCa patients and partners. Patients and their partners are likely to benefit from being well informed about the psychological effects of androgen deprivation on men beginning ADT. Copyright © 2015 John Wiley & Sons, Ltd.

A randomised controlled trial of a brief cognitive behavioural intervention for men who have hot flushes following prostate cancer treatment (MANCAN)

OBJECTIVE

Hot flushes and night sweats (HFNS) are experienced by up to 80% of prostate cancer patients undergoing androgen deprivation therapy (ADT). This study evaluates the effects of a guided self-help cognitive behavioural therapy (CBT) intervention on HFNS problem-rating (primary outcome), HFNS frequency, mood and health-related quality of life (secondary outcomes) in patients undergoing ADT.

METHODS

Patients reporting treatment-induced HFNS were randomly assigned to CBT (n = 33) or treatment as usual (TAU) (n = 35), stratified for cancer type. The CBT intervention included a booklet, CD plus telephone contact during a 4-week period. Validated self-report questionnaires were completed at baseline, 6 weeks and 32 weeks after randomisation. The primary outcome was HFNS problem rating (perceived burden of HFNS) at 6 weeks after randomisation. Potential moderators and mediators were examined. Data analysis was conducted on a modified intention-to-treat basis.

RESULTS

Compared with TAU, CBT significantly reduced HFNS problem rating (adjusted mean difference: -1.33, 95% CI -2.07 to -0.58; p = 0.001) and HFNS frequency (-12.12, 95% CI -22.39 to -1.84; p = 0.02) at 6 weeks. Improvements were maintained at 32 weeks, but group differences did not reach significance. There were significant reductions in negative HFNS Beliefs and Behaviours following CBT, but not in mood or quality of life.

CONCLUSIONS

Guided self-help CBT appears to be a safe and effective brief treatment for men who have problematic HFNS following prostate cancer treatments. Further research might test the efficacy of the intervention in a multicentre trial.

The Hot Flush Beliefs and Behaviour Scale for Men (HFBBS-Men) undergoing treatment for prostate cancer

OBJECTIVE

Hot flushes and night sweats (HFNS) are commonly experienced by men receiving treatment for prostate cancer. Cognitive behavioural therapy (CBT) has been found to be an effective treatment for HFNS in women, but cognitions and behavioural reactions to HFNS in men are under-researched. This study describes the development of the HFNS beliefs and behaviour scale for men.

METHODS

HFNS beliefs and behaviour items were generated from a qualitative study, from pilot interviews with men with prostate cancer and HFNS, and from scales used for women. 118 men with prostate cancer, aged above 18, English-speaking, who had minimum of seven HFNS weekly for at least 1 month, completed the initial measure, and measures of HFNS frequency, problem rating, anxiety and depression (HADS). Principal components analyses with orthogonal rotation determined the most coherent solution.

RESULTS

Exploratory factor analysis culminated in a 17-item HFNS beliefs and behaviour scale for men (HFBBS-Men) with three subscales: (1) HFNS social context and sleep, (2) Calm/Acceptance, (3) Humour/Openness. The subscales had reasonable internal consistency (Cronbach alpha 0.56-0.83). Validity was supported, by correlations between subscale 1, HFNS frequency, problem-rating and mood; men with locally advanced cancer more likely to adopt Calm/Acceptance and those with metastatic cancer Humour/Openness.

CONCLUSIONS

Preliminary analysis of the HFBBS-Men suggests that it is a psychometrically sound instrument, grounded in men's experiences. As a measure of cognitive and behavioural reactions to HF/NS, the HFBBS-Men should increase understanding of the mediators of outcomes of psychological interventions, such as CBT.

Network analysis of ChIP-Seq data reveals key genes in prostate cancer

Background

Prostate cancer (PC) is the second most common cancer among men in the United States, and it imposes a considerable threat to human health. A deep understanding of its underlying molecular mechanisms is the premise for developing effective targeted therapies. Recently, deep transcriptional sequencing has been used as an effective genomic assay to obtain insights into diseases and may be helpful in the study of PC.

Methods

In present study, ChIP-Seq data for PC and normal samples were compared, and differential peaks identified, based upon fold changes (with P-values calculated with t-tests). Annotations of these peaks were performed. Protein–protein interaction (PPI) network analysis was performed with BioGRID and constructed with Cytoscape, following which the highly connected genes were screened.

Results

We obtained a total of 5,570 differential peaks, including 3,726 differentially enriched peaks in tumor samples and 1,844 differentially enriched peaks in normal samples. There were eight significant regions of the peaks. The intergenic region possessed the highest score (51%), followed by intronic (31%) and exonic (11%) regions. The analysis revealed the top 35 highly connected genes, which comprised 33 differential genes (such as YWHAQ, tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein and θ polypeptide) from ChIP-Seq data and 2 differential genes retrieved from the PPI network: UBA52 (ubiquitin A-52 residue ribosomal protein fusion product 1) and SUMO2 (SMT3 suppressor of mif two 3 homolog 2) .

Conclusions

Our findings regarding potential PC-related genes increase the understanding of PC and provides direction for future research.

An investigation of the support needs of men and partners throughout the prostate cancer journey

OBJECTIVE

Prostate cancer is one of the mostly commonly diagnosed cancers in men. Unfortunately, the treatment for this cancer can have a number of negative side effects, both for the man himself and his partner. This study investigated the support needs of both men and partners throughout the prostate cancer journey and how this journey may be optimally managed.

METHODS

Thirty-one men who had undergone prostate cancer treatment within the last 6 years and 31 partners answered a questionnaire, which explored support care issues as identified in the literature and from focus groups.

RESULTS

Men and partners were moderately satisfied with information given regarding diagnosis, treatment and side effects, but partners were more satisfied with information relating to the particular chosen treatment. Men's understanding of their chosen treatment's potential side effects was significantly different from their understanding of diagnosis, cancer outcome, treatment options and selected treatment. Timing of information delivery was preferred by men at diagnosis, whereas partners preferred after the diagnosis. Men wanted more time to think about the diagnosis and treatment, whereas partners wanted an opportunity to discuss the diagnosis. The management of common side effects such as emotional changes, incontinence and erectile dysfunction was rated as 'somewhat' satisfactory.

CONCLUSION

Men and partners may have different educational and supportive needs throughout the prostate cancer journey that require attention and tailored management.

The lived experience of physically active older prostate cancer survivors on androgen deprivation therapy

This study sought to explore the lived experiences of physically active prostate cancer survivors on androgen deprivation therapy (ADT), who exercise individually. Three older men (74-88 years old) with prostate cancer, using ADT continuously for at least 12 months and regularly exercising for at least 6 months, participated in this qualitative pilot study, informed by interpretive phenomenology. Data were gathered using individual semi-structured interviews, audio recorded and transcribed verbatim. Coherent stories were drawn from each transcript and analyzed using iterative and interpretive methods. van Manen's lifeworld existentials provided a framework for interpreting across the research text. Three notions emerged: Getting started, Having a routine and Being with music. Together they reveal what drew the participants to exercising regularly despite the challenges associated with their cancer and treatments. This study provides insights into the benefits of, and what it means for, older men with prostate cancer to regularly exercise individually. These findings may assist cancer clinicians and other allied health professionals to be more attuned to prostate cancer survivors' lived experiences when undergoing ADT, allowing clinicians to better promote regular exercise to their patients as a foundational component of living well.

Validity and reliability of male andropause symptoms self-assessment questionnaire among elderly males in Khuzestan province of Iran

Background:

Andropause is a condition of decreasing testosterone in men that usually begins to occur at about 40 years of age. Many men find it difficult to acknowledge there may be a problem by refusing to even talk about the symptoms.

Aims:

The study was conducted to the standards of MASSQ (2012) within male older adults to introduce a relevant criterion.

Materials and Methods:

About 382 men with age range of 50-80 and with the mean age of 65.3 ± 2.32 were sampled with the cluster-ratio sampling method from the eight cities of Khuzestan province in southwestern Iran. The aged samples replied to the 25 items of MASSQ.

Results:

Coefficients of Cronbach's alpha (α = 0.89), split-half (0.91), convergent validity (0.72), divergent validity (−0.32), and criterion validity (0.67) were estimated, which were significant at P < 0.01. The exploratory factor analysis demonstrated that the 25-items of MASSQ for aged samples are organized into four factors (sexual, somatic, psychic, and behavioral) which clarify 79% of the scale's variance. Second-order confirmatory factor analysis pointed out that the factors are well-matched up onto a principal factor. Consequently, the four-factor model was well appropriate for the data by the fit index techniques for adjusting the scale [adjusted goodness of fit index = 0.92, goodness-of-fit statistic = 0.91, root mean square error of approximation = 0.006, incremental fit index = 0.94, normed fit index = 0.91, comparative fit index = 0.97].

Conclusions:

The results pointed to the well-adjusted reliability and validity of MASSQ and its usefulness for the relevant studies as well.

'You know I've joined your club… I'm the hot flush boy': a qualitative exploration of hot flushes and night sweats in men undergoing androgen deprivation therapy for prostate cancer

OBJECTIVE

Hot flushes and night sweats are common amongst menopausal women, and psychological interventions for managing these symptoms have recently been developed for women. However, flushes in men with prostate cancer, which commonly occur following androgen deprivation therapy (ADT), remain under-researched. This study is a qualitative exploration of flush-related cognitive appraisals and behavioural reactions reported by a sample of these men.

METHODS

Semi-structured, in-depth interviews were conducted with 19 men who were experiencing flushes after receiving ADT for prostate cancer. Framework analysis was used to generate and categorise emergent themes and explore associations between themes.

RESULTS

Five main cognitive appraisals included the following: changes in oneself, impact on masculinity, embarrassment/social-evaluative concerns, perceived control and acceptance/adjustment. There were men who held beliefs about the impact of flushes on their perceptions of traditional gender roles, who experienced shame and embarrassment due to concerns about the salience of flushes and perceptions by others and who experienced feelings of powerlessness over flushes. Powerlessness was associated with beliefs about the potentially fatal consequences of discontinuing treatment. Two other dominant themes included awareness/knowledge about flushes and management strategies. Experiences of flushes appeared to be influenced by upbringing and general experiences of prostate cancer and ADT.

CONCLUSIONS

The range of men's appraisals of, and reactions to, flushes generated from this qualitative exploration were broadly similar to those of menopausal women but differed in terms of the influence of masculinity beliefs. These findings could be used to inform future research and psychological interventions in this under-researched field.

Luteinizing hormone--releasing hormone agonists: a quick reference for prevalence rates of potential adverse effects

Men with prostate cancer (PCa) frequently undergo androgen deprivation therapy (ADT), typically in the form of a depot injection of luteinizing hormone-releasing hormone agonists (LHRHa). LHRHa are associated with many adverse effects (eg, hot flashes, sexual dysfunction, loss of muscle mass, osteopenia, metabolic syndrome), which drastically impact patient quality of life. This literature review, which includes a comprehensive table documenting prevalence rates, provides a quick reference for health care professionals involved in the care of men undergoing ADT with LHRHa. Primary sources were acquired from PubMed using the search terms "androgen deprivation therapy" and each potentially adverse effect (eg, "androgen deprivation therapy and hot flashes"). Commonly cited review articles were also examined for citations of original studies containing prevalence rates. More than 270 articles were reviewed. In contrast to many existing reviews, rates are cited exclusively from original sources. The prevalence rates, obtained from original sources, suggest that more than half of documented adverse effects are experienced by as many as 40% or more of patients. A critique of the literature is also provided. Although there is a vast literature of both original and review articles on specific adverse effects of LHRHa, the quality of research on prevalence rates for some adverse effects is subpar. Many review articles contain inaccuracies and do not cite original sources. The table of prevalence rates will serve as a quick reference for health care providers when counseling patients and will aid in the development of evidence-based patient education materials.

Fertility (male and female) and Menopause

The impact of oncologic treatments on fertility and menopausal symptoms is often significant for patients with cancer. Surgery, radiation, and chemotherapy can all damage the reproductive organs or the hypothalamic pituitary axis that controls them, impairing fertility and causing hormonally mediated symptoms such as hot flashes.

Understanding these risks and strategies to mitigate them may substantially improve cancer survivorship care. For both female and male patients who desire a future biologic child, there are a variety of fertility preservation techniques that should be considered. For cancer survivors who experience menopausal symptoms, lifestyle changes may be beneficial, and hormonal and nonhormonal pharmacologic agents are well proven to reduce symptom burden.

Prostate cancer treatments and their side effects are associated with increased insomnia

OBJECTIVE

Between 25% and 40% of prostate cancer patients report insomnia symptoms. Although a possible role of androgen deprivation therapy (ADT) and radiation therapy (RTH) and some of their side effects have been postulated, this issue has rarely been investigated. This study aimed to (1) compare the evolution of insomnia symptoms and somatic symptoms, which may affect sleep quality (i.e., hot flashes, night sweats, and urinary symptoms), in patients receiving combined ADT and RTH with that in patients receiving RTH only and (2) assess the mediating role of somatic symptoms in the relationship of ADT and RTH with insomnia symptoms.

METHODS

Sixty men scheduled to receive RTH for prostate cancer, with (n = 28) or without (n = 32) ADT, were assessed prior to receiving any treatment (baseline) and at seven additional times over 16 months (1, 2, 4, 6, 8, 12, and 16 months) using the Insomnia Severity Index and the Physical Symptoms Questionnaire.

RESULTS

A significant interaction effect was found indicating an increase in insomnia scores in ADT-RTH patients at 2, 4, and 6 months, as compared with baseline, and stable scores in RTH patients. A significant mediating role of hot flashes and night sweats was found in the relationship between ADT and insomnia symptoms. The relationship with RTH was also significantly mediated by these two symptoms albeit more strongly by excessive urinary frequency.

CONCLUSIONS

Androgen deprivation therapy is associated with an increased risk for insomnia, and side effects of ADT and RTH appear to play a role in the development of insomnia in this population.
