Severity of cardiovascular disease and health-related quality of life in men with prostate cancer: a longitudinal analysis from CaPSURE.
ObjectiveTo evaluate the influence of comorbid cardiovascular disease severity on health-related quality of life (HRQL) in men treated with radical prostatectomy (RP) or radiotherapy (RT) for early stage prostate cancer.MethodsSubjects (n=830) with non-metastatic disease who had been diagnosed in 2000-2002 were drawn from Cancer of the Prostate Strategic Urologic Research Endeavor (CaPSURE). We evaluated the influence of cardiovascular disease (CVD) severity on generic and disease-specific HRQL before and 6, 12, 18, and 24 months after treatment with RP or RT. HRQL was measured with the SF-36 and the UCLA Prostate Cancer Index.ResultsMen with moderate (n=193) or severe (n=51) cardiovascular disease had worse pre-treatment HRQL than did men without CVD (n=293) (P<0.01); HRQL scores were worse in men referred for RT. During 24 months of follow-up, men with moderate or severe CVD had worse SF-36 physical and mental component summaries and worse bowel function at all time points (P<0.05). Men with severe CVD also experienced a slower recovery in physical function (P=0.03) and sexual functioning (P=0.02) than did men without CVD.ConclusionsProstate cancer patients with moderate to severe CVD have worse HRQL during follow-up. Those with severe CVD recover their physical and sexual functioning more slowly after treatment
Predictive value of serial measurements of quality of life on all-cause mortality in prostate cancer patients: data from CaPSUREā¢ (cancer of the prostate strategic urologic research endeavor) database
Health-related quality of life (HRQOL) is a legitimate construct for evaluating treatment and its side effects. Recently, predictive value of HRQOL on survival also has been of interest. In light of the longer survival in patients with prostate cancer and importance of quality of life, we seek to evaluate the association between HRQOL and survival using traditional and novel techniques.
Patients from CaPSURE (Cancer of the Prostate Strategic Urologic Research Endeavor) who were treated within 6Ā months of diagnosis and had pre-treatment and sufficient post-treatment follow-up information constituted the study population. A sample consisting of 2,899 patients met the study criteria. SF-36 domains were used to measure HRQOL outcomes. Categorical variables were created for HRQOL based on the baseline distribution of the lower 10th percentile and the remainder of the patients. Association between HRQOL and survival (defined by all-cause mortality) in patients with prostate cancer was evaluated using Cox proportional hazards models controlling for age at diagnosis, type of treatment received, clinical risk classification, and number of comorbidities. Sequential bootstrap resampling was implemented to evaluate stability of the model. Univariate and multivariate Cox proportional hazards models were fit using various time points over the course of follow-up.
In the analysis looking at association of HRQOL baseline measurements, higher levels of physical function and general health were significantly associated with better survival (HR 0.49 95% CI 0.32ā0.78 and HR 0.51 95% CI 0.35ā0.75, respectively). Post-treatment analysis demonstrated similar results. In time-dependent analysis, higher levels of physical function, role physical, and general health were significantly associated with better survival (HR ranged from 0.57 to 0.65). In addition, analysis looking at change in HRQOL scores demonstrated an association between higher scores on physical function, role physical, vitality, social function, and general health and longer survival (HR ranged from 0.56 to 0.63).
This study demonstrated that several domains of HRQOL were significantly associated with survival in a large group of patients with localized prostate cancer. This association was maintained over the course of disease regardless of the time of the assessment. Results from our study have both research and clinical relevance. They could provide information that enable us to not only improve communication with patients and families, but also to develop interventions and treatments best suited for the patient

Among potent men post radical prostatectomy, does the need for phosphodiesterase inhibitors have an impact on sexual bother scores?
UnlabelledStudy Type - Therapy (case series) Level of Evidence 4. What's known on the subject? and What does the study add? Although phosphodiesterase inhibitor use post radical prostatectomy improves potency, little is known about its affects on sexual bother. We found no difference in sexual bother scores between patients who use and do not use phosphodiesterase inhibitors. This suggests that the current definition of potency, inclusive of medication use, is valid with respect to sexual bother.ObjectiveTo determine whether the current definition of potency, inclusive of phosphodiesterase inhibitor (PDEi) use, is valid with respect to sexual bother (SB). This will be assessed by characterizing the effect of PDEi use on SB scores in men who are potent post radical prostatectomy.Patients and methodsThe study population consisted of patients who were potent both before and after radical prostatectomy, with at least 2 years of follow-up. Disease-specific quality of life data were evaluated by the University of California, Los Angeles, Prostate Cancer Index (PCI) survey. The relationships between changes in sexual function (SF) and SB and use of PDEi over time were evaluated by mixed model analysis controlling for age, clinical risk group, marital status, and time of PCI assessment.ResultsOf the 246 patients who met the study criteria, 39% reported PDEi use at some point after treatment. PDEi use was not associated with improved SF (P= 0.81). Furthermore, PDEi use was not associated with a change in SB (P= 0.36). Both SF and SB were significantly associated with time of assessment and age, and SF and SB each improved over time. In addition, SB was significantly associated with marital status.ConclusionsIn this analysis, there was no difference in SF scores between men who were potent with or without the use of PDEi. Furthermore, there was no difference in SB scores between men who were potent with or without the use of PDEi. This suggests that the current, inclusive, definition of potency is valid with respect to SB

Health related quality of life in patients treated with multimodal therapy for prostate cancer.
PurposePatients with prostate cancer and high risk disease characteristics may benefit from multimodal therapy. However, the effects of multimodal therapy on health related quality of life have not been comprehensively described. We further characterized health related quality of life in patients treated with multimodal therapy.Materials and methodsPatient data were obtained from the CaPSURE database, a national disease registry of men with prostate cancer. Included patients received active primary therapy (ie surgery or various forms of radiation) for prostate cancer with or without adjuvant or neoadjuvant therapy, and had complete clinical data, including health related quality of life assessments at baseline and through 2 years after treatment. The association between health related quality of life outcomes and different primary therapies with and without adjuvant or neoadjuvant therapy over time was analyzed using a repeated measures mixed model for each primary therapy.ResultsA total of 2,204 men met the study criteria. As primary therapy 1,427 patients received radical prostatectomy, 267 received external beam radiation therapy and 510 received brachytherapy. When androgen deprivation therapy was included with radical prostatectomy, brachytherapy or external beam radiation therapy, there was a transient loss of sexual function that improved within 9 months postoperatively. When external beam radiation therapy was given with brachytherapy there was continuous worsening of urinary function and bother through 21 months.ConclusionsMultimodal therapy may lead to declines in health related quality of life especially in the domains of urinary function, urinary bother and sexual function. These effects must be considered and patients must be counseled appropriately before initiation of multimodal therapy
