Objectives: An increasingly important concern for clinicians who care for patients at the end of life is their spiritual well‐being and sense of meaning and purpose in life. In response to the need for short‐term interventions to address spiritual well‐being, we developed Meaning Centered Group Psychotherapy (MCGP) to help patients with advanced cancer sustain or enhance a sense of meaning, peace and purpose in their lives, even as they approach the end of life.

Cognitive Effects of Hormone Therapy in Men With Prostate Cancer : A Review

Christian J. Nelson; Jennifer S. Lee; Maria C. Gamboa; Andrew J. Roth

Men who receive androgen‐deprivation therapy (ADT) for prostate cancer experience several side effects from this treatment. A few recent studies have examined the cognitive implications of ADT and how they impact a patients treatment decision‐making, occupational pursuits, and quality of life. For this report, the authors explored possible mechanisms for this association, reviewed research in animal studies and aging men, and examined the growing literature focused on the relation between ADT and cognitive functioning in patients with prostate cancer.

INTRODUCTION Erectile function recovery (EFR) rates after radical prostatectomy (RP) vary greatly based on a number of factors, such as erectile dysfunction (ED) definition, data acquisition means, time-point postsurgery, and population studied. AIM To conduct a meta-analysis of carefully selected reports from the available literature to define the EFR rate post-RP. MAIN OUTCOME MEASURES EFR rate after RP. METHODS An EMBASE and MEDLINE search was conducted for the time range 1985-2007. Articles were assessed blindly by strict inclusion criteria: report of EFR data post-RP, study population >or=50 patients, >or=1 year follow-up, nerve-sparing status declared, no presurgery ED, and no other prostate cancer therapy. Meta-analysis was conducted to determine the EFR rate and relative risks (RR) for dichotomous subgroups. RESULTS A total of 212 relevant studies were identified; only 22 (10%) met the inclusion criteria and were analyzed (9,965 RPs, EFR data: 4,983 subjects). Mean study population size: 226.5, standard deviation = 384.1 (range: 17-1,834). Overall EFR rate was 58%. Single center series publications (k = 19) reported a higher EFR rate compared with multicenter series publications (k = 3): 60% vs. 33%, RR = 1.82, P = 0.001. Studies reporting >or=18-month follow-up (k = 10) reported higher EFR rate vs. studies with <18-month follow-up (k = 12), 60% vs. 56%, RR = 1.07, P = 0.02. Open RP (k = 16) and laparoscopic RP (k = 4) had similar EFR (57% vs. 58%), while robot-assisted RP resulted in a higher EFR rate (k = 2), 73% compared with these other approaches, P = 0.001. Patients <60 years old had a higher EFR rate vs. patients >or=60 years, 77% vs. 61%, RR = 1.26, P = 0.001. CONCLUSIONS These data indicate that most of the published literature does not meet strict criteria for reporting post-RP EFR. Single and multiple surgeon series have comparable EFR rates, but single center studies have a higher EFR. Younger men have higher EFR and no significant difference in EFR between ORP and LRP is evident.

Cancer-related communication, relationship intimacy, and psychological distress among couples coping with localized prostate cancer

Sharon L. Manne; Hoda Badr; Talia Zaider; Christian J. Nelson; David W. Kissane

IntroductionThe present study evaluated intimacy as a mechanism for the effects of relationship-enhancing (self-disclosure, mutual constructive communication) and relationship-compromising communication (holding back, mutual avoidance, and demand-withdraw communication) on couples’ psychological distress.MethodsSeventy-five men diagnosed with localized prostate cancer in the past year and their partners completed surveys about communication, intimacy, and distress.ResultsMulti-level models with the couple as unit of analyses indicated that the association between mutual constructive communication, mutual avoidance, and patient demand-partner withdraw and distress could be accounted for by their influence on relationship intimacy. Intimacy did not mediate associations between self-disclosure, holding back, and partner demand-patient withdraw communication and distress.Discussion/conclusionsThese findings indicate that the way in which couples talk about cancer-related concerns as well as the degree to which one or both partners avoid talking about cancer-related concerns can either facilitate or reduce relationship intimacy, and that it is largely by this mechanism that these three communication strategies impact psychological distress.Implications for cancer survivorsRelationship intimacy and how patients and partners communicate to achieve this intimacy is important for the psychological adjustment of early stage prostate cancer survivors and their partners.

INTRODUCTION For the practicing clinician, appreciating Peyronies disease (PD) significant negative psychological impact is apparent. Despite this, there exists not a single study using validated instruments assessing this issue. AIMS To document the effect of PD on the psychosocial status of men. MAIN OUTCOME MEASURES The Center for Epidemiological Studies Depression scale (CES-D) for evaluation of depression and the SF-36 for quality of life assessment. METHODS Men (N = 92; 54 +/- 11 years of age) presenting for PD evaluation completed the CES-D, Short Form-36 (SF-36), and an inventory regarding PD. Partners were not assessed. RESULTS A vast majority of men (88%) had a partner with a mean partner age of 49 +/- 11 years. The median duration of PD at presentation was 12 (1-360) months. As a whole, 48% were classified as depressed on the CES-D (26% moderate, 21% severe). These subjects were then placed into groups according to the length of time since diagnosis of PD. Length-of-time groups were: 0-6 months, 6-12 months, 12-18 months, and >18 months. The percent of men scoring above the CES-D cutoff for depression remained consistently high with no significant difference across time since diagnosis groups. These results are supported by data from the Mental Health subscale (MHS) of the SF-36 (lower scores indicate lower mental heath). For the entire sample, the MHS standardized mean of 46.80 was significantly lower (P < 0.05) than the general male population standardized mean of 50. The MHS means stayed consistently low (no statistical difference) across time since diagnosis groups. CONCLUSIONS Using validated instruments, we have demonstrated that 48% of men with PD have clinically meaningful depression that would warrant medical evaluation. This high level of depression stayed consistent across time since diagnosis. These data suggest that most men do not psychologically adjust to their diagnosis of PD and all men with PD should be considered appropriate mental health screening.

INTRODUCTION Infertility has been associated with anxiety, stress, and sexual problems in both men and women. AIM To assess quality of life, sexual health, and depression in the female partner of infertile couples. METHODS Couples presenting for the evaluation of infertility at two tertiary care medical centers were invited to participate in a survey study. MAIN OUTCOME MEASURES Female partners completed the Female Sexual Function Index (FSFI) and a modified Self-Esteem and Relationship (SEAR) Questionnaire. Male partners completed the SEAR and the International Index of Erectile Function (IIEF). Both partners completed the Center for Epidemiological Studies Depression Scale (CES-D) for depression and the Short Form-36 (SF-36) for general quality of life. Demographic, fertility, and comorbidity information was recorded. RESULTS One hundred and twenty-one couples constitute the study population. Mean female and male age was 32 +/- 5 and 35 +/- 7 years, respectively. Most (92%) couples were married. Mean duration of relationship and marriage were 6.4 +/- 3.9 and 3.8 +/- 3.2 years, respectively. Mean duration of attempted conception was 24 +/- 24 months. On CES-D, 19% of women had moderate and 13% had severe depression. Women reported significantly worse SF-36 Mental Health subscale scores (mean = 47.8, P < 0.05) compared with normative values. The mean total FSFI score was 28 +/- 7 (maximum score of 36), with 26% of the women scoring below 26.55, an established cut-off for high risk of female sexual dysfunction. FSFI scores had a modest positive correlation with male IIEF scores (r = 0.37, P < 0.01), and there was a trend toward a negative correlation with female CES-D scores (r = -0.16, P < 0.06). These relationships were maintained on multivariate analysis. CONCLUSIONS Depression and sexual dysfunction are prevalent in female partners of infertile couples. Female sexual function is positively correlated with male partner sexual function in this population.

PURPOSE We prospectively collected data on mental and physical health related quality of life as well as sexual and relationship function in couples presenting for the treatment of infertility. MATERIALS AND METHODS Infertile couples were invited to complete a demographic survey, the Short Form 36 and the Center for Epidemiological Studies Depression Inventory. Male partners completed the International Index of Erectile Function and the Self-Esteem and Relationship Quality scale. Female partners completed the Female Sexual Function Index and a version of the Self-Esteem and Relationship Quality Scale modified for women. Multiple regression analysis was conducted to assess for associations between partner responses. RESULTS A total of 121 couples were enrolled at 2 sites. Male partners reported significantly lower standardized scores on the Mental Health subscale of the Short Form 36 (mean 47.6, p <0.05) compared to normative values. Of the men surveyed 11% and 12% reported moderate or severe depression, respectively. There were 18% who had mild erectile dysfunction and 4% had moderate erectile dysfunction. The mean transformed score for the Self-Esteem and Relationship Quality Scale in our subjects was 29.44 (range 0 to 100). In multivariate analysis white race and partner Female Sexual Function Index score were significant predictors of International Index of Erectile Function Erectile Function Domain scores (p <0.01). Relationship duration and partner Self-Esteem and Relationship Quality Scale scores were significantly associated with male Self-Esteem and Relationship Quality Scale score on multivariate analysis. CONCLUSIONS Depression, erectile dysfunction and sexual relationship problems are prevalent among male partners of infertile couples. Partner sexual function is a significant predictor of male partner sexual function. Relationship duration and female partner assessment of relationship health are predictive of mens assessment of their relationship status.

INTRODUCTION Few couple-focused interventions have been developed to improve distress and relationship outcomes among men diagnosed with localized prostate cancer and their partners. AIMS We examined the effects of a five-session Intimacy-Enhancing Therapy (IET) vs. Usual Care (UC) on the psychological and relationship functioning of men diagnosed with localized prostate cancer and their partners. Pre-intervention levels of psychological and relationship functioning were evaluated as moderators of intervention effects. METHODS Seventy-one survivors and their partners completed a baseline survey and were subsequently randomly assigned to receive five sessions of IET or UC (no treatment). Eight weeks after the baseline assessment, a follow-up survey was administered to survivor and partner. MAIN OUTCOME MEASURES Distress, well-being, relationship satisfaction, relationship intimacy, and communication were investigated as the main outcomes. RESULTS IET effects were largely moderated by pre-intervention psychosocial and relationship factors. Those survivors who had higher levels of cancer concerns at pretreatment had significantly reduced concerns following IET. Similar moderating effects for pre-intervention levels were reported for the effects of IET on self-disclosure, perceived partner disclosure, and perceived partner responsiveness. Among partners beginning the intervention with higher cancer-specific distress, lower marital satisfaction, lower intimacy, and poorer communication, IET improved these outcomes. CONCLUSIONS IET had a marginally significant main effect upon survivor well-being but was effective among couples with fewer personal and relationship resources. Subsequent research is needed to replicate these findings with a larger sample and a longer follow-up.

PURPOSE To determine the predictors of distress in older patients with cancer. PATIENTS AND METHODS Patients age >or= 65 years with a solid tumor or lymphoma completed a questionnaire that addressed these geriatric assessment domains: functional status, comorbidity, psychological state, nutritional status, and social support. Patients self-rated their level of distress on a scale of zero to 10 using a validated screening tool called the Distress Thermometer. The relationship between distress and geriatric assessment scores was examined. RESULTS The geriatric assessment questionnaire was completed by 245 patients (mean age, 76 years; standard deviation [SD], 7 years; range, 65 to 95 years) with cancer (36% stage IV; 71% female). Of these, 87% also completed the Distress Thermometer, with 41% (n = 87) reporting a distress score of >or= 4 on a scale of zero to 10 (mean score, 3; SD, 3; range, zero to 10). Bivariate analyses demonstrated an association between higher distress (>or= 4) and poorer physical function, increased comorbid medical conditions, poor eyesight, inability to complete the questionnaire alone, and requiring more time to complete the questionnaire. In a multivariate regression model based on the significant bivariate findings, poorer physical function (increased need for assistance with instrumental activities of daily living [P = .015] and lower physical function score on the Medical Outcomes Survey [P = .018]) correlated significantly with a higher distress score. CONCLUSION Significant distress was identified in 41% of older patients with cancer. Poorer physical function was the best predictor of distress. Further studies are needed to determine whether interventions that improve or assist with physical functioning can help to decrease distress in older adults with cancer.
