Effect of androgen deprivation therapy on sexual function and bother in men with prostate cancer: A controlled comparison.

ABSTRACT: OBJECTIVES:The adverse sexual effects of androgen deprivation therapy (ADT) on men with prostate cancer have been well described. Less well known is the relative degree of sexual dysfunction and bother associated with ADT compared to other primary treatment modalities such as radical prostatectomy. We sought to describe the trajectory and relative magnitude of changes in sexual function and bother in men on ADT and to examine demographic and clinical predictors of ADT's adverse sexual effects. METHODS:Prostate cancer patients treated with ADT (n = 60) completed assessments of sexual function and sexual bother 3 times during a 1-year period after the initiation of ADT. Prostate cancer patients treated with radical prostatectomy only and not receiving ADT (n = 85) and men with no history of cancer (n = 86) matched on age and education completed assessments at similar intervals. RESULTS:Androgen deprivation therapy recipients reported worsening sexual function and increasing bother over time compared to controls. Effect sizes for the differences in sexual function were large to very large, and for bother were small to very large. Age younger than 83 years predicted relatively poorer sexual function, and age younger than 78 years predicted greater sexual bother at 12 months in men on ADT compared to men not on ADT. CONCLUSIONS:Most men on ADT for prostate cancer will never return to baseline levels of sexual function. Interventions focused on sexual bother over function and designed to help couples build and maintain satisfying relationship intimacy are likely to more positively affect men's psychological well-being while on ADT than medical or sexual aids targeting sexual dysfunction.

Project description:ContextDespite a lack of data, increasing numbers of patients are receiving primary androgen deprivation therapy (PADT) as an alternative to surgery, radiation, or conservative management for the treatment of localized prostate cancer.ObjectiveTo evaluate the association between PADT and survival in elderly men with localized prostate cancer.Design, setting, and patientsA population-based cohort study of 19,271 men aged 66 years or older receiving Medicare who did not receive definitive local therapy for clinical stage T1-T2 prostate cancer. These patients were diagnosed in 1992-2002 within predefined US geographical areas, with follow-up through December 31, 2006, for all-cause mortality and through December 31, 2004, for prostate cancer-specific mortality. Instrumental variable analysis was used to address potential biases associated with unmeasured confounding variables.Main outcome measuresProstate cancer-specific survival and overall survival.ResultsAmong patients with localized prostate cancer (median age, 77 years), 7867 (41%) received PADT, and 11,404 were treated with conservative management, not including PADT. During the follow-up period, there were 1560 prostate cancer deaths and 11,045 deaths from all causes. Primary androgen deprivation therapy was associated with lower 10-year prostate cancer-specific survival (80.1% vs 82.6%; hazard ratio [HR], 1.17; 95% confidence interval [CI], 1.03-1.33) and no increase in 10-year overall survival (30.2% vs 30.3%; HR, 1.00; 95% CI, 0.96-1.05) compared with conservative management. However, in a prespecified subset analysis, PADT use in men with poorly differentiated cancer was associated with improved prostate cancer-specific survival (59.8% vs 54.3%; HR, 0.84; 95% CI, 0.70-1.00; P = .049) but not overall survival (17.3% vs 15.3%; HR, 0.92; 95% CI, 0.84-1.01).ConclusionPrimary androgen deprivation therapy is not associated with improved survival among the majority of elderly men with localized prostate cancer when compared with conservative management.

Project description:BackgroundAndrogen deprivation therapy (ADT) is the mainstay therapy for men with prostate cancer. However, there are musculoskeletal side effects from ADT that increase the risk for osteoporosis and fracture, and can compromise the quality of life of these individuals. The objectives of this study are to determine the efficacy of a home-based walking exercise program in promoting bone health, physical function and quality of life in men with prostate cancer receiving ADT.Methods/designA 12-month prospective, single-blinded, randomized controlled trial will be conducted to compare the Exercise Group with the Control Group. Sixty men with prostate cancer who will be starting ADT will be recruited and randomly assigned to one of the two groups: the Exercise Group will receive instructions in setting up an individualized 12-month home-based walking exercise program, while the Control Group will receive standard medical advice from the attending physician. A number of outcome measures will be used to assess bone health, physical function, and health-related quality of life. At baseline and 12 months, bone health will be assessed using dual-energy X-ray absorptiometry. At baseline and every 3 months up to 12 months, physical function will be evaluated using the Functional Assessment of Chronic Illness Therapy - Fatigue Scale, Activities-specific Balance Confidence Scale, Short Physical Performance Battery, and Six-Minute Walk Test; and health-related quality of life will be assessed using the Functional Assessment of Cancer Therapy Prostate Module and the Medical Outcomes Study 12-item Short Form Health Survey Version 2. A mixed multiple analysis of variance will be used to analyze the data.DiscussionMusculoskeletal health management remains a challenge in men with prostate cancer receiving ADT. This study addresses this issue by designing a simple and accessible home-based walking exercise program that will potentially have significant impact on reducing the risk of fracture, promoting physical function, and ultimately improving the health-related quality of life in men with prostate cancer receiving ADT.Trial registrationClinicalTrials.gov: NCT00834392.
