Genitourinary Functioning and Depressive Symptoms Over Time In Younger Versus Older Men Treated for Prostate Cancer

A modified Delphi study to identify screening items to assess neglected sexual side-effects following prostate cancer treatment

Background

Neglected sexual side effects (NSSE) are a group of less common sexual side effects that may present after Prostate Cancer (PCa) treatment. There is currently no valid and reliable tool to identify these side effects. A modified Delphi study is an effective way of developing the content of such a screening tool.

Methods

A modified Delphi study was used to obtain consensus from a multi-disciplinary group of experts over 3 rounds during a 12 week period. Ten statements were presented containing 8 closed-ended statements on individual NSSEs, and 2 open-ended statements on psychosocial impact related to NSSE. Consensus was defined as a 75% strongly agree achievement on each statement, or the final statement evolution at the end of 3 rounds. Statement support in each round was determined by mean, standard deviation and range, after a numerical value was allocated to each statement during specific rounds. All three rounds were structured and suggestions and additions were incorporated in the statement evolution of the three rounds.

Results

Thirty-five participants were invited, and 27 completed Round 1 (RD 1), 23 participants completed RD2, and 20 participants completed RD3. All 3 rounds were completed in 12 weeks. Statement 1 (sexual arousal incontinence), statement 2 (climacturia) and statement 3 (orgasm intensity) reached consensus after RD2, and statement 9 (sexual dysfunction impact) and statement 10 (experiences) were removed after RD3. Statement 4 (orgasmic pain), statement 5 (anejaculation), statement 6 (sensory disturbances), statement 7 (penile length shortening) and statement 8 (penile curvature) were finalised after the conclusion of RD3. Statements 1–3 were the most stable statements with the most support and least amount of disagreement. Statements 4–8 were less stable, but support for them improved over the 3 rounds. Statements 9–10 both had good stability, but the support indicated that they needed to be removed from the set of statements. Statement 5 had the poorest range due to an outlier opinion.

Conclusions

Consensus was reached on the items making up the NSSE screening tool. Health care practitioners will be able to use this tool to identify the evidence of NSSE after PCa treatment. Further testing will be undertaken to confirm the reliability and validly of the tool.

Predictors of long-term distress in female partners of men diagnosed with prostate cancer

OBJECTIVE

Female partners of men with prostate cancer (PCa) experience heightened psychological distress; however, long-term distress for this group is not well described. We examined partner's psychological and cancer-specific distress over 2 years and predictors of change.

METHODS

A cohort of 427 female partners (63% response; mean age 62.6 y) of PCa survivors completed baseline (2-4 y post-PCa treatment) assessments of anxiety, depression, and cancer-specific distress and were followed up at 6, 12, 18, and 24 months. Caregiver burden, threat and challenge appraisal, self-efficacy, and dyadic adjustment were assessed as potential predictors of distress.

RESULTS

Over time, 23% to 25% of women reported anxiety; 8% to 11% depression; 5% to 6% high cancer-specific distress. Higher caregiver burden and more threat appraisals were associated with increased distress, anxiety, depression, and cancer-specific distress over time. Higher dyadic adjustment over time and more challenge appraisals at 24 months were associated with less distress, anxiety, and depression. Increased partner self-efficacy was associated with lower distress and depression at baseline.

CONCLUSIONS

A substantial subgroup of partners experience ongoing anxiety, with depression less prevalent but also persistent. Caregiver burden, partner self-efficacy, threat, and challenge appraisals present as potential supportive care targets.

Threat of Sexual Disqualification: The Consequences of Erectile Dysfunction and Other Sexual Changes for Gay and Bisexual Men With Prostate Cancer

Gay and bisexual (GB) men with prostate cancer (PCa) have been described as an "invisible diversity" in PCa research due to their lack of visibility, and absence of identification of their needs. This study examined the meaning and consequences of erectile dysfunction (ED) and other sexual changes in 124 GB men with PCa and 21 male partners, through an on-line survey. A sub-sample of 46 men with PCa and seven partners also took part in a one-to-one interview. ED was reported by 72 % of survey respondents, associated with reports of emotional distress, negative impact on gay identities, and feelings of sexual disqualification. Other sexual concerns included loss of libido, climacturia, loss of sensitivity or pain during anal sex, non-ejaculatory orgasms, and reduced penis size. Many of these changes have particular significance in the context of gay sex and gay identities, and can result in feelings of exclusion from a sexual community central to GB men's lives. However, a number of men were reconciled to sexual changes, did not experience a challenge to identity, and engaged in sexual re-negotiation. The nature of GB relationships, wherein many men are single, engage in casual sex, or have concurrent partners, influenced experiences of distress, identity, and renegotiation. It is concluded that researchers and clinicians need to be aware of the meaning and consequences of sexual changes for GB men when designing studies to examine the impact of PCa on men's sexuality, advising GB men of the sexual consequences of PCa, and providing information and support to ameliorate sexual changes.

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.

Health-Related Quality of Life, Psychological Distress, and Sexual Changes Following Prostate Cancer: A Comparison of Gay and Bisexual Men with Heterosexual Men

INTRODUCTION

Decrements in health-related quality of life (HRQOL) and sexual difficulties are a recognized consequence of prostate cancer (PCa) treatment. However little is known about the experience of gay and bisexual (GB) men.

AIM

HRQOL and psychosexual predictors of HRQOL were examined in GB and heterosexual men with PCa to inform targeted health information and support.

METHOD

One hundred twenty-four GB and 225 heterosexual men with PCa completed a range of validated psychosexual instruments.

MAIN OUTCOME MEASURE

Functional Assessment of Cancer Therapy-Prostate (FACT-P) was used to measure HRQOL, with validated psychosexual measures, and demographic and treatment variables used as predictors.

RESULTS

GB men were significantly younger (64.25 years) than heterosexual men (71.54 years), less likely to be in an ongoing relationship, and more likely to have casual sexual partners. Compared with age-matched population norms, participants in both groups reported significantly lower sexual functioning and HRQOL, increased psychological distress, disruptions to dyadic sexual communication, and lower masculine self-esteem, sexual confidence, and sexual intimacy. In comparison with heterosexual men, GB men reported significantly lower HRQOL (P = .046), masculine self-esteem (P < .001), and satisfaction with treatment (P = .013); higher psychological distress (P = .005), cancer related distress (P < .001) and ejaculatory concern (P < .001); and higher sexual functioning (P < .001) and sexual confidence (P = .001). In regression analysis, psychological distress, cancer-related distress, masculine self-esteem, and satisfaction with treatment were predictors of HRQOL for GB men (R2Adj = .804); psychological distress and sexual confidence were predictors for heterosexual men (R2Adj = .690).

CONCLUSION

These findings confirm differences between GB and heterosexual men in the impact of PCa on HRQOL across a range of domains, suggesting there is a need for GB targeted PCa information and support, to address the concerns of this "hidden population" in PCa care.

Defining young in the context of prostate cancer

The experience of prostate cancer is for most men a major life stress with the psychological burden of this disease falling more heavily on those who are younger. Despite this, being young as it applies to prostate cancer is not yet clearly defined with varied chronological approaches applied. However, men's responses to health crises are closely bound to life course and masculinities from which social roles emerge. This paper applied qualitative methodology (structured focus groups and semistructured interviews with expert informants) using interpretative phenomenological analysis to define what it means to be young and have prostate cancer. Structured focus groups were held with 26 consumer advisors (men diagnosed with prostate cancer who provide support to other men with prostate cancer or raise community awareness) and health professionals. As well, 15 men diagnosed with prostate cancer and in their 40s, 50s, or 60s participated in semi-structured interviews. Participants discussed the attributes that describe a young man with prostate cancer and the experience of being young and diagnosed with prostate cancer. Chronological definitions of a young man were absent or inconsistent. Masculine constructions of what it means to be a young man and life course characteristics appear more relevant to defining young as it applies to prostate cancer compared with chronological age. These findings have implications for better understanding the morbidities associated with this illness, and in designing interventions that are oriented to life course and helping young men reconstruct their identities after prostate cancer.

Comparing standard versus prosocial internet support groups for patients with breast cancer: a randomized controlled trial of the helper therapy principle

PURPOSE

Internet support group (ISG) members benefit from receiving social support and, according to the helper therapy principle, by providing support to others. To test the mental health benefits of providing support to others, this trial compared the efficacy of a standard ISG (S-ISG) and an enhanced prosocial ISG (P-ISG).

METHODS

A two-armed randomized controlled trial with 1-month pretest and post-test assessments was conducted with women (N = 184) diagnosed in the past 36 months with nonmetastatic breast cancer who reported elevated anxiety or depression. Women were randomly assigned to either the S-ISG or P-ISG condition. Both conditions included six professionally facilitated live chat sessions (90-minute weekly sessions) and access to an asynchronous discussion board; P-ISG also included structured opportunities to help and encourage others.

RESULTS

Relative to the S-ISG, participants in the P-ISG condition exhibited more supportive behaviors (emotional, informational, and companionate support), posted more messages that were other-focused and fewer that were self-focused, and expressed less negative emotion (P < .05). Relative to the S-ISG, participants in the P-ISG condition had a higher level of depression and anxiety symptoms after the intervention (P < .05).

CONCLUSION

Despite the successful manipulation of supportive behaviors, the P-ISG did not produce better mental health outcomes in distressed survivors of breast cancer relative to an S-ISG. The prosocial manipulation may have inadvertently constrained women from expressing their needs openly, and thus, they may not have had their needs fully met in the group. Helping others may not be beneficial as a treatment for distressed survivors of breast cancer.

Erectile Function Following Prostate Cancer Treatment: Factors Predicting Recovery

Prostate cancer represents the most common nonskin malignancy encountered in men, and the excellent long-term survival achieved in the majority of patients has allowed more attention to be given to the side effects associated with its treatment. Erectile function is one of the main concerns of patients when considering treatment options for prostate cancer. Not surprisingly, post-treatment sexual function is closely related to outcome satisfaction and has long-lasting effects on quality of life. Radical prostatectomy is currently the most commonly employed therapy for prostate cancer. Conflicting rates of erectile dysfunction have been reported after surgery, owing not only to different surgical techniques but also because of dissimilar patient populations and definitions. Providing accurate information to individual patients in regards to their chances of recuperating the ability to have intercourse after treatment is important not only because it allows patients to make informed decisions but also because it has the potential to reduce treatment dissatisfaction. This article mainly focuses on discussing predictors of erectile function after radical prostatectomy. Patient factors, surgical aspects, including comparisons between open, laparoscopic, and robotic approaches, and postoperative management issues that impact sexual outcomes are evaluated. Prediction models combining multiple factors are described. The definition and chronology of erectile function recovery and impact of sexual function on quality of life after surgery are also discussed. Teloken PE and Mulhall JP.

Couple distress after localised prostate cancer

BACKGROUND

The experience of the diagnosis of prostate cancer is distressing for both men and their partners. The present study describes the prevalence of psychological distress in men with prostate cancer and their partners, and the predictors of adjustment outcomes.

METHODS/DESIGN

A cross-sectional survey of 189 prostate cancer patients who were scheduled for or had undergone surgery for localised prostate cancer and their partners assessed socio-demographic variables, masculine self-esteem and social intimacy, psychological adjustment and quality of life.

RESULTS

Overall, patients and partners reported low distress; however, female partners were more anxious with 36 % reporting mild to severe anxiety. For men, masculine self-esteem and time since diagnosis were most strongly related to mental health status; urinary bother most influenced physical quality of life. For female partners, the man's psychological distress and his sexual bother were most strongly related to her mental health status; higher social intimacy was most strongly associated with physical quality of life.

CONCLUSION

The correlates of distress after the diagnosis of prostate cancer differ between patients and female partners. For men, masculine self-esteem may be most crucial, whereas for women, her partner's level of distress may matter most. Research to better understand these interactions is needed.

Loss of masculine identity, marital affection, and sexual bother in men with localized prostate cancer

INTRODUCTION

Erectile dysfunction (ED) is one of the most frequent sources of distress after treatment for prostate cancer (PCa), yet evidence suggests that men do not easily adjust to loss of sexual function over time. A hypothesized determinant of men's adaptation to ED is the degree to which they experience a loss of masculine identity in the aftermath of PCa treatment.

AIMS

The aims of this study were (i) to describe the prevalence of concerns related to diminished masculinity among men treated for localized PCa; (ii) to determine whether diminished masculinity is associated with sexual bother, after controlling for sexual functioning status; and (iii) to determine whether men's marital quality moderates the association between diminished masculinity and sexual bother.

METHODS

We analyzed cross-sectional data provided by 75 men with localized PCa who were treated at one of two cancer centers. Data for this study were provided at a baseline assessment as part of their enrollment in a pilot trial of a couple-based intervention.

MAIN OUTCOME MEASURES

The sexual bother subscale from the Prostate Health-Related Quality-of-Life Questionnaire and the Masculine Self-Esteem and Marital Affection subscales from Clark et al's PCa-related quality-of-life scale.

RESULTS

Approximately one-third of men felt they had lost a dimension of their masculinity following treatment. Diminished masculinity was the only significant, independent predictor of sexual bother, even after accounting for sexual functioning status. The association between diminished masculinity and sexual bother was strongest for men whose spouses perceived low marital affection.

CONCLUSIONS

Diminished masculinity is a prominent, yet understudied concern for PCa survivors. Regardless of functional status, men who perceive a loss of masculinity following treatment may be more likely to be distressed by their ED. Furthermore, its impact on adjustment in survivorship may rely on the quality of their intimate relationships.

Distinguishing between-person and within-person relationships in longitudinal health research: arthritis and quality of life

BACKGROUND

Many health measures (e.g., blood pressure, quality of life) have meaningful fluctuation over time around a relatively stable mean level for each person.

PURPOSE

This didactic paper describes two closely related statistical models for examining between-person and within-person relationships between two or more sets of measures collected over time: the latent intercept model with correlated residuals (LI) in structural equation modeling framework and the multivariate multilevel model (MVML) in multilevel modeling framework.

RESULTS

We illustrated that the basic LI model and the MVML model are equivalent. We presented an illustrative example using a national arthritis data resource to examine between-person and within-person relationships of symptom status, functional health, and quality of life in arthritis patients.

DISCUSSION

Additional design and modeling issues for the treatment of missing data are considered. We discuss contexts in which one of the two models may be preferred. Mplus and SAS syntax are available.

Intervening to improve psychological outcomes for men with prostate cancer

BACKGROUND

Prostate cancer is the most common cancer in men in the Western world with well-described negative effects from treatments. However, outcomes are highly heterogeneous. A Phase 3 trial of a psycho-educational intervention was undertaken, aiming to reduce cancer-specific and decision-related distress and improve quality of life for men newly diagnosed with localised prostate cancer.

METHODS

Seven hundred forty (81.7%) men were recruited after diagnosis and before treatment and randomised to a tele-based nurse-delivered five-session psycho-educational intervention (N = 372) or usual care (N = 368). Participants were assessed before treatment and 2, 6, 12 and 24 months post-treatment. Outcome measures included cancer-specific and decision-related distress, cognitive judgmental adjustment, subjective well-being, and domain-specific and health-related quality of life. Social support was assessed as a potential moderator.

RESULTS

No unconditioned effects were found. Classification analyses on pre-randomisation measures distinguished three subgroups: younger, higher education and income men (N =  90); younger, lower education and income men (N = 106); and older men (N = 344). Younger, higher education and income men showed positive intervention effects for cancer-specific distress (p = 0.008) and mental health (p = 0.042). By contrast, for younger, lower education men, participation in the intervention was associated with decreases in cognitive judgmental adjustment over time (p = 0.006).

CONCLUSIONS

Response to intervention and adjustment over time varied according to previous sexual functioning, age, educational level and income. How to best intervene with younger, low education, low income men with prostate cancer is a critical future research question.
