The association between erectile dysfunction and depressive symptoms in men treated for prostate cancer

Mental health outcomes in elderly men with prostate cancer

OBJECTIVE

To examine the burden of mental health issues (MHI), namely anxiety, depressive disorders, and suicide, in a population-based cohort of older men with localized prostate cancer and to evaluate associations with primary treatment modality.

PATIENTS AND METHODS

A total of 50,856 men, who were 65 years of age or older with clinically localized prostate cancer diagnosed between 1992 and 2005 and without a diagnosis of mental illness at baseline, were abstracted from the Surveillance, Epidemiology, and End Results-Medicare database. The primary outcome of interest was the development of MHI (anxiety, major depressive disorder, depressive disorder not elsewhere classified, neurotic depression, adjustment disorder with depressed mood, and suicide) after the diagnosis of prostate cancer.

RESULTS

A total of 10,389 men (20.4%) developed MHI during the study period. Independent risk factors for MHI included age ≥ 75 years (hazard ratio [HR] = 1.29); higher comorbidity (Charlson comorbidity index ≥ 3, HR = 1.63); rural hospital location (HR = 1.14); being single, divorced, or widowed (HR = 1.12); later year of diagnosis (HR = 1.05); and urinary incontinence (HR = 1.47). Black race (HR = 0.79), very high-income status (HR = 0.87), and definitive treatment (radical prostatectomy [RP], HR = 0.79; radiotherapy [RT], HR= 0.85, all P<0.001) predicted a lower risk of MHI. The rates of MHI at 10 years were 29.7%, 29.0%, and 22.6% in men undergoing watchful waiting (WW), RT, and RP, respectively.

CONCLUSION

Older men with localized prostate cancer had a significant burden of MHI. Men treated with RP or RT were at a lower risk of developing MHI, compared with those undergoing WW, with median time to development of MHI being significantly greater in those undergoing RP compared with those undergoing RT or WW.

American Cancer Society prostate cancer survivorship care guidelines

Prostate cancer survivors approach 2.8 million in number and represent 1 in 5 of all cancer survivors in the United States. While guidelines exist for timely treatment and surveillance for recurrent disease, there is limited availability of guidelines that facilitate the provision of posttreatment clinical follow-up care to address the myriad of long-term and late effects that survivors may face. Based on recommendations set forth by a National Cancer Survivorship Resource Center expert panel, the American Cancer Society developed clinical follow-up care guidelines to facilitate the provision of posttreatment care by primary care clinicians. These guidelines were developed using a combined approach of evidence synthesis and expert consensus. Existing guidelines for health promotion, surveillance, and screening for second primary cancers were referenced when available. To promote comprehensive follow-up care and optimal health and quality of life for the posttreatment survivor, the guidelines address health promotion, surveillance for prostate cancer recurrence, screening for second primary cancers, long-term and late effects assessment and management, psychosocial issues, and care coordination among the oncology team, primary care clinicians, and nononcology specialists. A key challenge to the development of these guidelines was the limited availability of published evidence for management of prostate cancer survivors after treatment. Much of the evidence relies on studies with small sample sizes and retrospective analyses of facility-specific and population databases.

Exploring the feasibility and acceptability of couple-based psychosexual support following prostate cancer surgery: study protocol for a pilot randomised controlled trial

BACKGROUND

Men who undergo surgery for prostate cancer frequently experience significant side-effects including urinary and sexual dysfunction. These difficulties can lead to anxiety, depression and reduced quality of life. Many partners also experience psychological distress. An additional impact can be on the couple relationship, with changes to intimacy, and unmet psychosexual supportive needs in relation to sexual recovery and rehabilitation. The aim of this exploratory randomised controlled trial pilot study is to determine the feasibility and acceptability of a novel family-relational-psychosexual intervention to support intimacy and reduce distress among couples following prostate cancer surgery and to estimate the efficacy of this intervention.

METHODS/DESIGN

The intervention will comprise six sessions of psychosexual and relationship support delivered by experienced couple-support practitioners. Specialist training in delivering the intervention will be provided to practitioners and they will be guided by a detailed treatment manual based on systemic principles. Sixty-eight couples will be randomised to receive either the intervention or standard care (comprising usual follow-up hospital appointments). A pre-test, post-test design will be used to test the feasibility of the intervention (baseline, end of intervention and six-month follow-up) and its acceptability to couples and healthcare professionals (qualitative interviews). Both individual and relational outcome measures will assess sexual functioning, anxiety and depression, couple relationship, use of health services and erectile dysfunction medication/technologies. An economic analysis will estimate population costs of the intervention, compared to usual care, using simple modelling to evaluate the affordability of the intervention.

DISCUSSION

Given the increasing incidence and survival of post-operative men with prostate cancer, it is timely and appropriate to determine the feasibility of a definitive trial through a pilot randomised controlled trial of a family-relational-psychosexual intervention for couples. The study will provide evidence about the components of a couple-based intervention, its acceptability to patients and healthcare professionals, and its influence on sexual and relational functioning. Data from this study will be used to calculate sample sizes required for any definitive trial.

Development of UK recommendations on treatment for post-surgical erectile dysfunction

AIM

To develop a management strategy (rehabilitation programme) for postsurgical erectile dysfunction (ED) among men experiencing ED associated with treatment of prostate, bladder or rectal cancer that is suitable for use in a UK NHS healthcare context.

METHODS

PubMed literature searches of ED management together with a survey of 13 experts in the management of ED from across the UK were conducted.

RESULTS

Data from 37 articles and completed questionnaires were collated. The results discussed in this study demonstrate improved objective and subjective clinical outcomes for physical parameters, sexual satisfaction, and rates of both spontaneous erections and those associated with ED treatment strategies.

CONCLUSION

Based on the literature and survey analysis, recommendations are proposed for the standardisation of management strategies employed for postsurgical ED.

Quality of Life and Sexual Health in the Aging of PCa Survivors

Prostate cancer (PCa) is the most common malignancy in elderly men. The progressive ageing of the world male population will further increase the need for tailored assessment and treatment of PCa patients. The determinant role of androgens and sexual hormones for PCa growth and progression has been established. However, several trials on androgens and PCa are recently focused on urinary continence, quality of life, and sexual function, suggesting a new point of view on the whole endocrinological aspect of PCa. During aging, metabolic syndrome, including diabetes, hypertension, dyslipidemia, and central obesity, can be associated with a chronic, low-grade inflammation of the prostate and with changes in the sex steroid pathways. These factors may affect both the carcinogenesis processes and treatment outcomes of PCa. Any treatment for PCa can have a long-lasting negative impact on quality of life and sexual health, which should be assessed by validated self-reported questionnaires. In particular, sexual health, urinary continence, and bowel function can be worsened after prostatectomy, radiotherapy, or hormone treatment, mostly in the elderly population. In the present review we summarized the current knowledge on the role of hormones, metabolic features, and primary treatments for PCa on the quality of life and sexual health of elderly Pca survivors.

Sexual and reproductive health in cancer survivors

As patients live longer after cancer diagnosis and treatment, attention to symptoms and quality of life (QoL) are of increasing importance both during treatment and throughout survivorship. Two complications of multi-modal cancer treatment that can profoundly affect both men and women are sexual dysfunction and infertility. Survivors at highest risk for treatment-related sexual dysfunction are those with tumors that involve the sexual or pelvic organs and those whose treatment affects the hormonal systems mediating sexual function. Sexual dysfunction may not abate without appropriate intervention. Therefore, early identification and treatment strategies are essential. Likewise, multiple factors contribute to the risk of infertility from cancer treatment and many cancer patients of reproductive age would prefer to maintain their fertility, if possible. Fortunately, advances in reproductive technology have created options for young newly diagnosed patients to preserve their ability to have a biologic child. This paper will focus on the sexual and reproductive problems encountered by cancer survivors and discuss some treatment options.

A longitudinal study of anxiety, depression and distress as predictors of sexual and urinary quality of life in men with prostate cancer

OBJECTIVE

To evaluate the prevalence of depression, anxiety and distress among active surveillance (AS) and radical prostatectomy (RP) patients. To evaluate the impact of these symptoms at baseline on urinary and sexual quality of life at follow-up.

PATIENTS AND METHODS

Patients managed with AS or RP who completed validated questionnaires assessing levels of depression, anxiety, distress and urinary (UF) and sexual function (SF) and bother comprised the final analytic cohort. These measures were completed at baseline, within 1 year, and between 1 and 3 years from baseline. Mixed model repeated measures analysis was used to examine associations between mental health at baseline and sexual and urinary outcomes in a subset of RP patients with complete follow-up.

RESULTS

Among 679 men who comprised the study cohort, baseline prevalence of moderate or higher levels of depression or anxiety were low (<5%), while levels of mild depression or anxiety ranged from 3-16% over time. Baseline levels of elevated distress ranged from 8-20%. Among men who provided data at baseline and follow-up, there were no significant differences between AS and RP patients in the proportion of men with elevated levels of depression, anxiety, or distress. Among 177 men who underwent RP and had complete follow-up moderate or higher levels of depression or anxiety appeared to be associated with post-treatment SF and bother, while elevated levels of distress were associated with post-treatment UF.

CONCLUSION

Moderate or higher levels of depression or anxiety were low in men with localised prostate cancer but were associated with sexual outcomes, while elevated distress was associated with urinary outcomes. Greater attention should be paid to mental health symptoms among men with prostate cancer, as these symptoms may be associated with quality of life outcomes.

Men's experience with sexual dysfunction post-rectal cancer treatment: a qualitative study

In an effort to address reports from men that their sex life is worse after treatment for rectal cancer, this qualitative study was designed to better understand their experience with sexual dysfunction following rectal cancer treatment, thus providing information on the adaptation of a psycho-educational sexual health intervention for male rectal cancer survivors and simultaneously investigating barriers and promoters that would influence their participation in a psycho-educational sexual health intervention. Thirteen male rectal cancer survivors who were treated at Memorial Sloan-Kettering Cancer Center (MSKCC) for rectal cancer participated (median time post-treatment was 6.4 years). Six survivors participated in individual semi-structured phone interviews, and seven others took part in focus groups. We performed standard procedures of qualitative thematic text analysis, which involved independent review of interview and focus group transcripts by several analysts followed by consensus meetings to identify key themes. Participants reported bowel dysfunction (N = 13, or 100%) and erectile dysfunction (N = 12, or 92%) as chief complaints. The participants thought a psychoeducational sexual health intervention post-surgery would be helpful because it would provide educational information regarding the etiology of their problems and treatments to improve their sexual health (N = 8, or 62%). Most participants' primary concern immediately after treatment was surviving their disease; improving sexual functioning seemed to become more important over time. Barriers to potentially participating in a psycho-educational sexual health intervention included geographical distance from MSKCC (N = 3, or 3/13) and the risk of embarrassment when discussing sexual issues (N = 5, or 5/13). Men reported that a psycho-educational sexual health intervention would be helpful to improve their sexual functioning post-treatment. Discussion of bowel issues and logistical concerns gave information on the psycho-educational sexual health intervention.

Eroticization as a factor influencing erectile dysfunction treatment effectiveness

We review both the medical and psychosocial literature on factors influencing male potency in order to better understand why erectile dysfunction (ED) treatments, PDE5 drugs in particular, are abandoned when otherwise effective. We incorporate anecdotal data from websites and list serves dedicated to helping patients deal with iatrogenic ED. Our goal is to distinguish between ED treatments that are medicalized versus eroticized, and how partner participation may influence their effectiveness. Recently it has been shown that ED treatment effectiveness is aided by the involvement of the patient's partner. This permits an erotic association between the partner and the ED 'aid'. We extend this idea to suggest that having the partner involved as early as possible in the discussion of treatment, and their presence at the time of prescription, should improve ED aid effectiveness. Eroticization of ED aids shifts the focus from a perceived disability of the patient toward the sexual pleasure provided by the partner. We further suggest that ED aids used without the partner's knowledge will undermine intimacy and ultimately the treatment's effectiveness. Unpartnered patients should be advised about the importance of informing potential partners about their use of such aids, as openness and honesty may increase intimacy in the long run.

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.

Factors associated with adherence to physical activity guidelines in patients with prostate cancer

OBJECTIVE

This study aimed to estimate the proportion of patients with prostate cancer (PCa) meeting the National Physical Activity Guidelines of Australia (NPAGA) and determine sociodemographic and medical factors associated with meeting these guidelines. Secondary aims included examining physical activity (PA) levels by treatment type and domain (leisure, work, transport and domestic) and establishing a predictive model of the likelihood that men with PCa would meet NPAGA.

METHODS

A questionnaire was mailed to 638 men with PCa attending for treatment at the Alfred, Cabrini or Latrobe Regional Hospitals during 2010 and 2011, with a response rate of 59%. Measures included International Physical Activity Questionnaire, Hospital Anxiety and Depression Scale, Functional Assessment of Cancer Therapy - Prostate and sociodemographic items. Inclusion criteria were English speaking men aged 40 to 80 years, who had undergone radiotherapy (RT) between 9 and 30 months prior to the survey.

RESULTS

Of 356 men with PCa, less than half were meeting NPAGA (41.9%). Lower education and quality of life (QoL), a higher number of comorbid conditions and symptoms of depression and anxiety were associated with decreased leisure-time PA. Patients treated with androgen deprivation therapy were significantly less active than patients treated with RT only. Logistic regression analyses indicated that the likelihood of meeting NPAGA was significantly lower with higher levels of depressive symptoms and lower levels of education.

CONCLUSIONS

Meeting NPAGA is associated with higher QoL and psychosocial well-being in men with PCa. These findings contribute important information for targeting PA interventions to PCa survivors.

Back to baseline: erectile function recovery after radical prostatectomy from the patients' perspective

INTRODUCTION

A variety of erectile function recovery (EFR) rates are reported post-radical prostatectomy (RP), with some suggesting EFR rates over 90% [1]. Clinical experience suggests that patients view EFR as getting back to their baseline (BTB) erectile functioning (EF) without the use of medication.

AIM

This study explores EFR defined as BTB.

METHOD

Men pre-RP and 24 months post-RP completed the Erectile Function Domain (EFD) of the International Index of Erectile Function and one question on phosphodiesterase type 5 inhibitor (PDE5i) use. Men using a PDE5i at baseline were excluded.

MAIN OUTCOME MEASURES

At 24 m, "back to baseline" was defined as achieving the baseline EFD score (within 1 point or higher). Analyses included descriptive statistics, chi-square, and logistic regression.

RESULTS

One hundred eighty men had an average age at RP of 59 (SD = 7) years. When including men who were using a PDE5i at 24 months, 43% (N = 78, 95% CI: 36-51%) returned BTB. When considering BTB without the use of a PDE5i, 22% (N = 39, 95% CI: 16% to 28%) returned BTB. When focusing on a subset of men with baseline EFD ≥ 24 (N = 132), 36% (N = 47, 95% CI: 28% to 44%) returned BTB at 24 months using a PDE5i and 16% (N = 21, 95% CI: 11% to 23%) without the use of a PDE5i. For this group, there was a significant difference by age (<60 years, 23% vs. ≥ 60 years, 4%, P < 0.001), which remained a significant predictor (OR = 6.25, 95% CI: 1.88 to 50, P < 0.001) in multivariable analysis.

CONCLUSIONS

Twenty-two percent of the entire sample and 16% of the men with functional (EFD ≥ 24) baseline erections returned to BTB EF without the use of medication. Only 4% of men who were ≥ 60 years old with functional erections pre-surgery achieved BTB EF. Although gaining partial EF is also important, men pre-RP should be educated on EFR and the chance of "back to baseline" EF.

Erectile dysfunction and depression in patients with chronic lead poisoning

In this retrospective study, we aimed to evaluate the relationship between erectile dysfunction (ED) and chronic lead intoxication (CLI) as well as the role of depression in this relationship. We compared the findings of 26 male patients with CLI and 24 male patients as the control group between November 2008 and January 2009. The blood lead levels and smoking index of patients were evaluated for both groups. The International Index of Erectile Dysfunction-erectile function domain (EFD) and Beck Depression Inventory (BDI) were obtained and reviewed in both groups. The mean blood lead levels of patients in the CLI and control groups were 42.1 and 3.2 μg dl(-1) respectively (P < 0.01). The mean interval of lead exposure of patients in CLI group was 71.5 (6-360) months. EFD scores of patients in CLI group were significantly lower, and number of patients with ED in CLI group was statistically higher (P < 0.05). BDI scores of patients in CLI group were significantly higher (P < 0.05). We detected a mildly negative and statistically significant relationship between the EFD scores and blood lead levels (r = -0.453 and P < 0.05). Our results showed that the increased frequency of ED is an independent factor in CLI group.

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.

Prostate cancer and sexual function

Prostate cancer is now ranked fifth in incidence among cancers in Korean adult males. This is attributable to the more Westernized dietary style which increases the morbidity of prostate cancer and the development of cancer diagnostic technologies, such as prostate-specific antigen and advanced medical systems, increasing the rate of prostate cancer diagnosis. Prostate cancer effects include not only erectile dysfunction caused by the disease itself, but also by psychiatric disorders caused by prostate cancer or its treatments. Prostate cancer by itself reduces sexual desire and the frequency of sexual intercourse. Additionally, surgery or hormonal therapy to block testosterone further increases the frequency of erectile dysfunction. Erectile dysfunction following radical prostatectomy is primarily attributable to nerve injury caused by intraoperative nerve traction, thermal injury, ischemic injury, and local inflammatory reactions. Additionally, the absence of nocturnal penile tumescence causes persistent hypoxia of the corpus cavernosum, which, secondarily, causes anatomical and functional changes in the corpus cavernosum. Preservation of erectile function is one of the most significant issues for patients with local prostate cancer. Erectile dysfunction following radical prostatectomy is known to have various prognoses, depending on preservation of the neurovascular bundle, patient age, and preoperative erectile status. Intracavernosal injections, PDE5 inhibitors, and penile rehabilitation therapy using a vacuum constriction device after radical prostatectomy are known to improve the recovery of erectile function. Recently, testosterone replacement therapy has also drawn attention as a treatment method.

Evaluation of the association of prostate cancer-specific anxiety with sexual function, depression and cancer aggressiveness in men 1 year following surgical treatment for localized prostate cancer

BACKGROUND

Cancer-specific anxiety (CSA) can affect treatment decisions and is common in men following surgery for prostate cancer (PCa). We hypothesized that CSA is also associated with factors affecting quality of life. Herein, we examine the association of CSA with psychosocial factors and PCa aggressiveness in a cohort of men 1 year after prostatectomy for localized PCa.

METHODS

From our prospective PCa Registry, we identified 365 men who underwent prostatectomy for localized PCa who completed the Memorial Anxiety Scale for Prostate Cancer (MAX-PC) and Expanded Prostate Cancer Index Composite at 1-year follow-up. We evaluated the association of scores on the MAX-PC with demographics, clinicopathologic features, sexual function, and depression scores using Wilcoxon Rank Sum and Kendall's tau correlation tests.

RESULTS

Higher scores on the MAX-PC (i.e., higher anxiety) are associated with younger age (p < 0.01) and non-Caucasian race (p < 0.01). Men with higher MAX-PC scores also reported poor sexual satisfaction/function (p < 0.01) and increasing depressive symptoms (p < 0.01). Finally, although higher anxiety is associated with several pathologic features of aggressiveness (stage, positive margins, PSA at 1 year; all p-values < 0.01), we noted several men with clinically indolent disease who reported significant anxiety.

CONCLUSIONS

Our data suggest that higher levels of CSA are associated with poor sexual function and increased depressive symptoms 1 year after prostatectomy. Moreover, we noted demographic and pathologic features associated with higher CSA as well. If confirmed, our data support development of models to predict men at high risk of CSA following PCa surgery and targeted referral for additional counseling.

Erectile function, incontinence, and other quality of life outcomes following proton therapy for prostate cancer in men 60 years old and younger

BACKGROUND

This study sought to evaluate patient-reported health-related quality of life following proton therapy for prostate cancer in men ≤ 60 years old.

METHODS

Between August 2006 and January 2010, 262 hormone-naive men ≤ 60 years old were treated with definitive proton therapy for prostate cancer. Before treatment and every 6 months after treatment, patients filled out the Expanded Prostate Index Composite (EPIC) and the International Index of Erectile Function (IIEF) questionnaires. Potency was defined as successful sexual intercourse in the prior month or an EPIC sexual summary (SS) score ≥ 60.

RESULTS

Median follow-up was 24 months; 90% of men completed follow-up EPIC forms within the last year. For EPIC urinary, bowel, and hormone subscales, the average decline from baseline to 2 years was ≤5 points, except for bowel function (5.2 points). SS scores declined 12.6 points after 2 years. Potency rates declined by 11% from baseline at 2 years, but 94% of men were potent with a baseline IIEF > 21, body mass index < 30, and no history of diabetes. At 2 years after treatment, only 1.8% of men required a pad for urge incontinence. On multivariate analysis, factors associated with a significant decline in SS score were mean penile bulb dose ≥40 cobalt Gy equivalents (P = .012) and radiation dose ≥ 80 cobalt Gy equivalents (P = .017); only diabetes was significantly associated with impotence (P = .015).

CONCLUSIONS

Young men undergoing proton therapy for treatment of prostate cancer have excellent outcomes with respect to erectile dysfunction, urinary incontinence, and other health-related quality of life parameters during the first 2 years after treatment. Longer follow-up is needed to confirm these findings.
