A comparison of general, genitourinary, bowel, and sexual quality of life among long term survivors of prostate, bladder, colorectal, and lung cancer

ObjectivesStudies of local stage prostate cancer survivors suggest that treatments carry risk of persistent impotence, incontinence, and bowel dysfunction. To examine impacts of cancer type and side effects on health-related quality of life (HRQoL) in long-term cancer survivorship, we evaluated 5-year follow-up of patients with prostate cancer and compared results with a matched group of male long-term survivors of other local-stage cancers. Materials and MethodsWe examined genitourinary, bowel and sexual symptoms, and general quality of life. Matched survivors of colorectal, lung, and bladder cancers were recruited via registries in 3 different regions in the United States. Patients were surveyed 3–5 years after diagnosis with the SF-12 and EPIC to evaluate general mental and physical health-related quality of life (HRQoL) and patient function and bother. ResultsWe analyzed responses from long-term prostate (n = 77) and bladder, colorectal, and lung cancer (n = 124) patients. In multivariate analysis, long-term local stage prostate cancer survivors had significantly higher SF-12 physical component scores but did not differ from long-term survivors of other cancers in terms of their SF-12 mental summary scores. Prostate survivors had similar mental, urinary, bowel, and sexual HRQoL compared to long-term survivors of other local stage cancers. ConclusionLong-term general and prostate-specific HRQoL was similar between local stage prostate and bladder, colorectal, and lung patients with cancer. Future research focusing on factors other than initial treatment and the cancer type per se may provide more meaningful information regarding factors that predict disparities on HRQoL among longer-term survivors of early stage male cancers.

Prostate-specific health-related quality of life and patient-physician communication — A 3.5-year follow-up

ObjectiveThe aim of this study is to examine associations between prostate-specific health-related quality of life (HRQOL) and aspects of patient-physician communication in localized prostate cancer treatment. MethodsData of patients with localized prostate cancer were collected at 6-month intervals over a 3.5-year period within a prospective, observational study (HAROW). Data collection comprised D’Amico risk categories, the Charlson Comorbidity Index, patient-physician communication (information, shared decision making, support, devotion), and prostate-specific HRQOL (incontinence aid, urinary symptoms, bowel symptoms, hormonal treatment-related symptoms, sexual functioning, sexual activity). Data of N = 1722 patients undergoing radical prostatectomy were analyzed by longitudinal multilevel analysis. ResultsThe mean patient age was 65 years; 31% had a low risk and 38% an intermediate risk of cancer growth and spread; 73% had a Charlson Comorbidity Index of 0. Significant associations were found between prostate-specific HRQOL and shared decision making, support and devotion. Patient information was not significantly associated with aspects of prostate-specific HRQOL. ConclusionPatient reported long term outcomes are associated with aspects of patient-physician communication in prostate cancer patients. Patients feeling involved by their urologists experience less side effects of (surgical) treatment. Practice implicationsSpecial communication training programmes should be developed and implemented for urologists.

Health-related quality of life in men with prostate cancer undergoing active surveillance versus radical prostatectomy, external-beam radiotherapy, prostate brachytherapy and reference population: a cross-sectional study

BackgroundThe purpose of this study is to describe Health-Related Quality of Life (HRQoL) of localized prostate cancer patients in an Active Surveillance (AS) program, and to compare them with those undergoing radical prostatectomy (RP), external-beam radiotherapy (XRT) and brachytherapy (BT).MethodsMulti-institutional pooled cross-sectional analysis on patients in an AS protocol: < 75 years old; pathologically confirmed LPC (maximum of three positive cylinders); Gleason score < 3 + 4; clinical stage T1a-T2b; and PSA < 15 ng/ml. Exclusion criteria for this study were: less than 6 months in AS, termination of AS protocol, or incomplete data. Patients in AS were matched with those treated with RP, XRT or BT from the ‘Spanish Multicentric Study of Clinically Localized Prostate Cancer’ cohort according to risk group, time from treatment selection to HRQoL survey, and age. Prostate-specific (EPIC) and generic (SF-36) HRQoL instruments were completed. Analysis was stratified by HRQoL survey moment (>or < 2.5 years from treatment selection), and age (>or < 70 years old).ResultsMedian of time from treatment selection to HRQoL survey in the total 396 patients (99 per treatment group) was 2.4 years (range 0.5–8.3). Patients in AS presented higher (better) urinary incontinence scores than RP ones in both stratus of time from treatment selection to HRQoL survey (92.6 vs 67.0 and 81.4 vs 64.4, p < 0.01). Patients in AS for < 2.5 years presented greater sexual scores than any active treatment (p < 0.01), but only statistically higher than RP for those in AS for longer than 2.5 years. The magnitude of the differences between AS and RP groups in both EPIC domains ranged from moderate (0.7 SD) to large (1.0 SD).Regardless of treatment applied, patients presented similar and slightly increased SF-36 scores than US general population reference norms. Nonetheless, patients in AS for < 2.5 years reported worse outcomes than other treatment groups on physical health domains, especially in bodily pain (0.5–0.6 SD), and vitality (0.6–0.8 SD).ConclusionsConsidering patients’ well-being, AS can be a good therapeutic option due to the low impact caused on urinary continence and sexual function. However, longitudinal studies are required to take into account HRQoL evolution over time.

Material and behavioral financial hardship as predictors of health-related quality of life in a diverse cohort of cancer survivors.

145 Background: Financial hardship is common among cancer survivors, but its association with health-related quality of life (HRQOL) unknown. Methods: We utilized data from 570 black participants the Detroit Research on Cancer Survivors (ROCS) cohort study diagnosed with breast, colorectal, lung or prostate cancer since 1/1/13 and diagnosed or treated at the Karmanos Cancer Institute, and 402 white survivors meeting the same criteria. HRQOL was measured using the functional assessment of cancer therapy-general (FACT-G) and its subscales of physical, social, emotional and functional wellbeing, and site-specific measures. We fit linear regressions to estimate associations between material (debt, borrowing, selling assets, reduced income) and behavioral (skipping medication, not seeing a doctor, refusing treatment due to cost) financial hardship (MFH and BFH, respectively) and HRQOL. Adjusted models include demographic, socioeconomic, and treatment-related factors. Results: Overall, 50.3% of participants experienced material and 17.6% experienced behavioral financial hardship. In unadjusted models, HRQOL scores were 0.39 (95% CI 0.27, 0.51) standard deviations (SD) lower in those reporting any MFH. MFH was associated with significantly lower physical, emotional, and functional wellbeing scores, and with lower scores on breast-, colorectal-, and prostate-specific HRQOL measures. Total HRQOL was 0.68 SD (95% CI 0.52, 0.84) lower for participants who reported BFH than those who did not, and BFH was inversely associated with each subscale and each cancer-specific measure. In adjusted models, HRQOL scores were 0.15 (95% CI 0.03, 0.27) SD lower among participants reporting MFH and remained inversely associated with physical and functional wellbeing. BFH was associated with 0.42 (95% CI 0.27, 0.57) SD lower HRQOL scores and remained inversely associated with physical, social, emotional, and functional wellbeing; and with breast- and prostate-specific measures. Conclusions: MFH and BFH are associated with lower HRQOL among diverse cancer survivors. Addressing BFH in particular may improve HRQOL among survivors, particularly those with breast and prostate cancer.

Quality of life after low-dose rate-brachytherapy for prostate carcinoma \u2013 long-term results and literature review on QLQ-C30 and QLQ-PR25 results in published brachytherapy series

BackgroundPatient-reported health-related quality of life (HRQOL) differs between treatment options for prostate carcinoma. Long-term HRQOL data in brachytherapy series are scarce. Therefore, we analyzed prostate-specific and general HRQOL in patients treated with brachytherapy for prostate carcinoma after long-term follow-up.MethodsTwo hundred ninety-six patients with prostate carcinoma were treated with brachytherapy (01/1998–11/2003). General and prostate-specific HRQOL were measured using EORTC-QLQ-C30 and EORTC-QLQ-PR25, respectively. Patients were asked to complete the questionnaires after a median follow-up of 141 (119–181) months. QLQ-C30 results were compared to the German reference population. QLQ-PR25 results were compared to an earlier follow-up after a median of 51 months (no published QLQ-PR25 reference population for comparison). Additionally, a literature review on HRQOL data in brachytherapy series was performed.ResultsOne hundred six (35.8%) patients were lost to follow-up, 70 (23.6%) had died. 120 (40.5%) patients were contacted. 80 questionnaires were returned (27% of the original cohort; 91% of alive patients were ≥70 years). Sexual activity declined over time (mean scores: 40.5 vs. 45.5; p = 0.006), hormonal treatment-related symptoms, problems associated with incontinence aids, and burden of obstructive urinary symptoms did not differ significantly compared to the 51-month follow-up. General HRQOL was numerically better in our cohort as compared to the German reference population (> 16% relative difference for both age strata; < 70 and ≥70 years).ConclusionsOur results indicate that symptom-burden after long-term follow-up and associated prostate-specific HRQOL remains relatively stable from 51 to 141 months. General HRQOL in surviving patients was numerically better compared to the reference population.

The ProCaSP study: quality of life outcomes of prostate cancer patients after radiotherapy or radical prostatectomy in a cohort study.

BackgroundThis study describes and compares health-related quality of life (HRQOL) of prostate cancer patients who received either radical prostatectomy (nerve-sparing, nsRP, or non-nerve-sparing, nnsRP) or radiotherapy (external RT, brachytherapy, or both combined) for treatment of localised prostate cancer.MethodsThe prospective, multicenter cohort study included 529 patients. Questionnaires included the IIEF, QLQ-C30, and PORPUS-P. Data were collected before (baseline), three, six, twelve, and twenty-four months after treatment. Differences between groups’ baseline characteristics were assessed; changes over time were analysed with generalised estimating equations (GEE). Missing values were treated with multiple imputation. Further, scores at baseline and end of follow-up were compared to German reference data.ResultsThe typical time trend was a decrease of average HRQOL three months after treatment followed by (partial) recovery. RP patients experienced considerable impairment in sexual functioning. The covariate-adjusted GEE identified a significant - but not clinically relevant - treatment effect for diarrhoea (b = 7.0 for RT, p = 0.006) and PORPUS-P (b = 2.3 for nsRP, b = 2.2 for RT, p = 0.045) compared to the reference nnsRP. Most of the HRQOL scores were comparable to German norm values.ConclusionsFindings from previous research were reproduced in a specific setting of a patient cohort in the German health care system. According to the principle of evidence-based medicine, this strengthens the messages regarding treatment in prostate cancer and its impacts on patients’ health-related quality of life. After adjustment for baseline HRQOL and other covariates, RT patients reported increased symptoms of diarrhoea, and nnsRP patients decreased prostate-specific HRQOL. RP patients experienced considerable impairment in sexual functioning. These differences should be taken into account by physicians when choosing the best therapy for a patient.Electronic supplementary materialThe online version of this article (doi:10.1186/s12894-015-0025-6) contains supplementary material, which is available to authorized users.

Longitudinal change in health-related quality of life after intensity-modulated radiation monotherapy for clinically localized prostate cancer

Purpose The purpose of the study is to assess longitudinal changes in general and disease-specific health-related quality-of-life (HRQOL) indices after intensity-modulated radiotherapy (IMRT) monotherapy for patients with localized prostate cancer (PCA).Methods Between 2006 and 2010, 91 patients with localized PCA underwent IMRT monotherapy and were enrolled into this prospective study. At baseline, and at 3, 6, 12, and 24 months after IMRT, the general and prostate-specific HRQOL were estimated using physical (PCS) and mental component summaries (MCS) calculated using the Medical Outcomes Study 8-Item Short Form Health Survey and Expanded Prostate Cancer Index Composite (EPIC).ResultsFor 2 years, there were no significant changes in EPIC scores in all subscales of urinary domain, hormonal function, and bother. Bowel and sexual function scores decreased after IMRT and did not return to those at baseline (p = 0.006 and < 0.001, respectively). PCS began to decrease at 3 months after IMRT and then returned to the baseline score at 24 months. In contrast, the MCS score began to significantly increase after IMRT, and thereafter the score remained constant until 24 months (p < 0.001). On multivariate logistic regression analysis, urinary (p = 0.003) and sexual functions (p = 0.0005) at baseline were identified as significant predictors of EPIC urinary irritative/obstructive score and sexual function at 24 months after IMRT.ConclusionUrinary function, including irritative/obstruction symptoms and hormonal function, was not affected by IMRT. However, bowel and sexual function decreased after IMRT. These findings will provide important information for PCA patients considering IMRT.

Comparison of Distribution‐ and Anchor‐Based Approaches to Infer Changes in Health‐Related Quality of Life of Prostate Cancer Survivors

To determine the minimal important difference (MID) in generic and prostate-specific health-related quality of life (HRQoL) using distribution- and anchor-based methods. Prospective cohort study of 602 newly diagnosed prostate cancer patients recruited from an urban academic hospital and a Veterans Administration hospital. Participants completed generic (SF-36) and prostate-specific HRQoL surveys at baseline and at 3, 6, 12, and 24 months posttreatment. Anchor-based and distribution-based methods were used to develop MID estimates. We compared the proportion of participants returning to baseline based on MID estimates from the two methods. MID estimates derived from combining distribution- and anchor-based methods for the SF-36 subscales are physical function = 7, role physical = 14, role emotional = 12, vitality = 9, mental health = 6, social function = 9, bodily pain = 9, and general health = 8; and for the prostate-specific scales are urinary function = 8, bowel function = 7, sexual function = 8, urinary bother = 9, bowel bother = 8, and sexual bother = 11. Proportions of participants returning to baseline values corresponding to MID estimates from the two methods were comparable. This is the first study to assess the MID for generic and prostate-specific HRQoL using anchor-based and distribution-based methods. Although variation exists in the MID estimates derived from these two methods, the recovery patterns corresponding to these estimates were comparable.

Impact of nocturia on disease-specific quality of life for men with localized prostate cancer

We assessed the impact of nocturia on the general and disease-specific health-related quality of life (HRQOL) for men with localized prostate cancer. A total of 620 men with prostate cancer were enrolled to our study. All of the subjects completed the questionnaires before primary treatment. We evaluated general HRQOL with the Short Form 36-Item Health Survey (SF-36). The prostate-specific HRQOL was assessed with the University of California, Los Angeles Prostate Cancer Index (PCI). Night-time urinary frequency was assessed by the seventh score of the International Prostate Symptom Score. Of the 581 men, 47 (8%) men reported no nocturia, while 189 (32%) were categorized with one void per night and 345 (59%) with two or more voids per night. Disease-specific HRQOL, including urinary function, bowel function, and sexual function, was negatively associated with increase in frequency of nocturia. The subjects who reported two or more voids per night had significantly lower scores than those of the no nocturia or one void per night group in several domains of the SF-36 and PCI. Based on the proportion odds model, age, urinary function, bowel function, and sexual function showed a strong association with frequency of nocturia. We found a strong association between the frequency of nocturia and disease-specific HRQOL as well as general HRQOL. Increased severity of nocturia is negatively correlated with overall health status and HRQOL outcomes.

The burden of out‐of‐pocket and indirect costs of prostate cancer

Out-of-pocket and indirect (OPI) costs play an important role in prostate cancer (PCa) outcomes research. We sought to analyze OPI costs of newly diagnosed PCa patients receiving either radical prostatectomy (RP) or external beam radiation therapy (EBRT). Prospective cohort design was used to recruit 512 newly diagnosed PCa patients from urology clinics of an urban academic hospital and a Veterans Administration medical center. Participants provided demographic information and completed self-reported generic and prostate-specific Health Related Quality of Life (HRQoL) and indirect-cost surveys at baseline and at 3, 6, 12, and 24 months follow-up. Linear mixed models were applied to study the association between OPI costs, treatment and HRQoL outcomes. Propensity scores adjusted for potential confounders and Bonferroni correction was used to account for multiple testing. Total mean OPI costs varied between RP group and EBRT group at 3-month ($5576 vs. $2010), 6-month ($1776 vs. $2133), 12-month ($757 vs. $774), and at 24-month follow-up ($458 vs. $871). Linear mixed models indicated that RP was associated with lower medication costs (OR = 0.61, CI = 0.48-0.89) and total OPI costs (OR = 0.71, CI = 0.64-0.92). Total OPI costs were inversely related to most of the generic HRQoL items. Similarly, prostate-specific HRQoL items of urinary function (OR = 0.72; adjusted-CI = 0.58-0.84), bowel function (OR = 0.96; adjusted-CI = 0.78-0.98), sexual function (OR = 0.85; adjusted-CI = 0.72-0.92), urinary bother (OR = 0.79; adjusted-CI = 0.67-0.83), and sexual bother (OR = 0.88; adjusted-CI = 0.76-0.93) were inversely related to OPI costs. OPI costs of PCa care are substantial and vary across time and treatment.

Association between utility and treatment among patients with prostate cancer

To analyze the association between utility, treatment, and generic and prostate-specific health-related quality of life (HRQoL) among patients with prostate cancer. In this longitudinal cohort study, we recruited 201 (>or=45 years) newly diagnosed patients with prostate cancer from urology clinics of an urban academic hospital. Participants completed Quality of Wellbeing (QWB-SA), generic (SF-36), and prostate-specific (UCLA-PCI) HRQoL surveys prior to treatment and up to 24 months post-treatment. Clinical and demographic data were obtained via medical chart review, and utility scores were computed using QWB-SA. To analyze the relationship between treatment and utility, we used linear mixed effects models, after adjusting for covariates and propensity score. Similar models were used to examine the association between generic and prostate-specific HRQoL and utility. Mean baseline utility was comparable between radical prostatectomy (RP) and external beam radiation therapy (EBRT) groups (0.73 vs. 0.69, P=0.1750). Mixed effects models indicated that RP was associated with higher utility at 24 month (OR=1.12, P=0.027), after controlling for covariates. RP was associated with improved functioning for role physical, role emotional, vitality, mental health and bodily pain, and impaired urinary function. Higher scores on generic health subscales were indicative of higher utility. Also, for prostate-specific HRQoL, higher scores on bowl function, sexual function, urinary bother, and bowel bother were associated with higher utility. Treatment appears to have significant association with post-treatment utility. Thus, utility assessment provides an important quantitative tool to support patient and physician clinical treatment decision-making process in prostate cancer care.

Satisfaction with Care: A Measure of Quality of Care in Prostate Cancer Patients

Patients' assessment of satisfaction with care, quality of care, and outcomes has become a central issue in patient-centered prostate cancer (PCa) care. We sought to analyze the association between patient-reported satisfaction with care and health-related quality of life (HRQoL) in newly diagnosed PCa patients. Prospective cohort design was used to recruit 590 newly diagnosed PCa patients from an urban academic hospital and a VA hospital. Participants completed satisfaction with care (CSQ-8) and HRQoL (SF-36 and UCLA-PCI) surveys prior to treatment and at 3, 6, 12, and 24 months' follow-up. Cross-lagged analysis was used to ascertain the causal direction between satisfaction with care and HRQoL. Propensity scores were used to adjust for potential selection bias between treatment groups. Linear mixed models were used to analyze the association between satisfaction with care, process of care (treatment), and outcomes (generic and prostate-specific HRQoL) after adjusting for covariates. Cross-lagged correlation results are consistent with a cause-effect association between HRQoL and satisfaction with care. After controlling for clinical and demographic covariates, radical prostatectomy (RP) treatment was associated with higher satisfaction with care (odds ratio [OR], 7.9; P = 0.043). Improved generic and prostate-specific HRQoL were associated with higher satisfaction with care, after adjusting for demographic and clinical covariates. Satisfaction with care appears to be associated with process of care and outcomes of care. Assessment of satisfaction with care is useful for evaluating the quality of PCa care. Satisfaction with care is an important arena in cancer outcomes research, whose full potential remains unexploited.

Predictors of patient reported outcomes and cost of care in younger men with newly diagnosed prostate cancer

The proportion of younger men (<65 years) diagnosed with prostate cancer (PCa) has increased significantly. We sought to analyze the association between race/ethnicity, biochemical recurrence risk and outcomes in younger men with PCa. In this prospective cohort study, we recruited 318 younger men with newly diagnosed PCa. Participants completed generic and prostate-specific Health Related Quality of Life (HRQoL), out-of-pocket cost and satisfaction with care surveys at baseline and at 3, 6, 12, and 24 months of follow-up. Health resource utilization and cost data were obtained from the hospital based administrative databases. We compared time to return to baseline (RTB) of HRQoL scores across groups. Survival curves were used to compare mean time to RTB across groups. Linear mixed effects (LMEs) and generalized linear (GLM) models were used to analyze the association of race/ethnicity and biochemical recurrence groups with outcomes. African Americans reported lower generic and prostate-specific HRQoL scores at diagnosis and required more time to RTB values for generic HRQoL. The results of LME models showed that low risk of biochemical recurrence was associated with better physical function, vitality, mental health, and general health. For prostate-specific HRQoL items, low risk of biochemical recurrence was associated with impaired urinary function and better bowel function and bowel bother. GLM model showed that treatment, hospital type and comorbidity were associated with cost. Biochemical recurrence risk and treatment groups, not ethnicity, were associated poorer post-treatment outcomes. This information is important in planning for and communicating with patients about post-treatment care.

Ethnic variation in return to baseline values of patient‐reported outcomes in older prostate cancer patients

Ethnic variation in patient-reported outcomes such as health-related quality of life (HRQoL) and satisfaction with care are understudied areas in the management of elderly prostate cancer (PCa) patients. In this prospective cohort study, between the years 2002 and 2004, the authors recruited 214 older (>or=65 years) men with newly diagnosed PCa from an urban academic hospital and a Veterans Administration hospital. Participants completed generic (SF-36), prostate-specific (UCLA-PCI) HRQoL, and satisfaction with care (CSQ-8) surveys at baseline and at 3, 6, and 12-months follow-up. Clinically significant difference was used to compute return to baseline. The authors compared time to return to baseline HRQoL after controlling for confounding variables by using ANOVA and log-linear models. Survival curves were used to compare time to return to baseline across ethnicity. Regression analysis revealed that age and marital status, not ethnicity, were independent predictors of radical prostatectomy, rather than radiation treatment. African Americans reported lower HRQoL scores at diagnosis and required a longer time to return to baseline. Log-linear analysis indicated that African-American ethnicity was associated with lower 12-month scores for role physical (odds ratio [OR], 0.46; standard error [SE], 0.40), role emotional (OR, 0.37; SE, 0.43), bodily pain (OR, 0.74; SE, 0.10), urinary function (OR, 0.90; SE, 0.11), and urinary bother (OR, 0.72; SE, 0.17). Both groups reported comparably high levels of satisfaction with care. African-American elderly exhibited poorer outcomes and required a longer time to return to baseline HRQoL. These differences highlight the need for discussion with patients and families prior to treatment about expectations and the need for support services post-treatment.

Health‐related quality of life and satisfaction with care among older men treated for prostate cancer with either radical prostatectomy or external beam radiation therapy

To analyse health-related quality of life (HRQoL) and satisfaction with care across potential curative treatments for older patients newly diagnosed with prostate cancer. In a prospective cohort study we recruited 115 older patients (> or =65 years) newly diagnosed with prostate cancer from the urology clinics of an urban academic and a Veterans' Administration (VA) hospital. Patients completed generic (Short Form-36), prostate-specific (University of California Los Angeles Prostate Cancer Index) HRQoL, and Client Satisfaction with Care (CSQ-8) surveys before treatment with either radical prostatectomy (RP) or external beam irradiation (EBRT) and at 3, 6 and 12 months afterward. Clinical and demographic data were obtained via medical chart review. A repeated-measures analysis of variance was used to examine changes in generic and prostate cancer-specific HRQoL between treatments. Log-linear regression was used to analyse the factors associated with 12-month HRQoL scores, and Kaplan-Meier survival curves were used to compare the return to baseline values for HRQoL. The RP group had significantly higher income, education and better general health than the EBRT group. Age (odds ratio 0.5, 95% confidence interval 0.32-0.82), non-VA hospital (28.8, 2-402) and prostate-specific antigen level at diagnosis (2.8, 1.05-7.5) were associated with RP. The analysis results indicated that the RP group had higher scores for generic HRQoL subscales of physical function (P = 0.019), role emotional (P = 0.037), vitality (P = 0.033) and general health (P = 0.05) than the EBRT group. A log-linear regression model for predicting the 12-month scores showed that RP was associated with higher scores for most of the generic HRQoL and bowel function (odds ratio 1.12, P = 0.03), urinary bother (1.6, P = 0.014) and bowel bother (1.5, P = 0.013). Being older was associated with a lower score on bowel function (0.98, P = 0.05) and sexual function (0.92, P = 0.05). Satisfaction with care was comparable between treatment groups at baseline and at the follow-up. Older patients tolerate RP well from the HRQoL perspective and thus decisions for therapy in this age cohort should not be based primarily on age.

Health-Related Quality-of-Life in Low-Income, Uninsured Men with Prostate Cancer

The objective was to describe health-related quality-of-life (HRQOL) in low-income men with prostate cancer. Subjects were drawn from a statewide public assistance prostate cancer program. Telephone and mail surveys included the RAND 12-item Health Survey and UCLA Prostate Cancer Index Short Form and were compared with normative age-matched men without cancer from the general population reported on in the literature. Of 286 eligible men, 233 (81%) agreed to participate and completed the necessary items. The sample consisted of 51% Hispanics, 23% non-Hispanic whites, and 17% African Americans. The low-income men had worse scores in every domain of prostate-specific and general HRQOL than had the age-matched general population controls. The degree of disparity indicated substantial clinical differences in almost every domain of physical and emotional functioning between the sample group and the control group. Linear regression modeling determined that among the low-income men, Hispanic race, and income level were predictive of worse physical functioning, whereas only comorbidities predicted mental health. Low-income patients with prostate cancer appear to have quality-of-life profiles that are meaningfully worse than age-matched men from the general population without cancer reported on in the literature.

Early quality of life in patients with localized prostate carcinoma

Men with localized prostate carcinoma are faced with important treatment decisions, and quality of life (QoL) information has become a crucial element of decision making. The first objective of this study was to compare the early, health-related QoL (HRQoL) of men with localized prostate carcinoma who were treated with radical prostatectomy, external beam radiotherapy, or brachytherapy. A second objective was to identify demographic and psychosocial variables that predict HRQoL. Two-hundred fifty-six men with localized prostate carcinoma were interviewed within 7 weeks of treatment initiation. The interview included measures of prostate-specific HRQoL (the University of California-Los Angeles Prostate Cancer Index), general HRQoL (the SF-36), and psychosocial variables. After adjusting for covariates, treatment group differences were found for both prostate specific HRQoL and general HRQoL. Men who underwent prostatectomy reported more urinary and sexual problems and more general physical dysfunction compared with men who were treated with either form of radiation therapy. Men who were treated with brachytherapy reported the fewest problems in sexual function and the least general physical dysfunction. Few treatment group differences were found in mental functioning. Both demographic factors and psychosocial factors predicted HRQoL. Older men and African-American men reported more physical problems than younger men and Caucasian men, respectively. A supportive social environment, high self-efficacy, and high self-esteem were predictive of better HRQoL. Shortly after undergoing treatment for localized prostate carcinoma, men who underwent radical prostatectomy, older men, and African-American men are at heightened risk for experiencing prostate-specific and general deficits in HRQoL. Having psychosocial resources from which to draw may enhance HRQoL.

Self-assessed health-related quality of life in men who have completed radiotherapy for prostate cancer: instrument validation and its relation to patient-assessed bother of symptoms.

The purpose of this study was to develop a psychometrically reliable and valid questionnaire to assess the disease-specific dimensions of health-related quality of life (HRQOL) in the urinary function (UF), bowel function (BF), and sexual function (SF) domains of prostate cancer (PCa) patients treated with radiation therapy. Patients were given a six-page questionnaire using Likert-type questions assessing three HRQOL dimensions during their follow-up visits after completing radiotherapy. Scales created from an earlier study were utilized and tested for reliability and validity. In addition, we assessed the relationship between these dimensions and the degree to which a decreased HRQOL increases the degree to which patients feel bothered about their symptoms. There are two scales within each dimension: BF, Urgency and Daily Living; UF, Urgency and Weakness of Stream; SF, Interest/Satisfaction and Impotence. Internal-consistency reliability coefficients (Cronbach's alpha) for the proposed scales range from 0.48 to 0.92, and all item-scale correlations and divergence correlations validate the use of the scales, ranging from 0.49 to 0.89. The validity of these scales is also confirmed by the rising median scores with rising reported levels of patient-perceived "bother." The different dimensions have differing quantitative influences on patients. We have developed a prostate-specific HRQOL instrument that is an adequate and suitable tool for measuring HRQOL along three distinct dimensions for patients who have completed radiotherapy for PCa. Psychometric standards for reliability and validity were met for the proposed scales. Moreover, positive correlations were found between these dimensions and how bothered patients were by their symptoms, suggesting important relationships that should be followed in PCa patients after radiotherapy. Certain scales have strong influences on patient-perceived "bothersomeness" of symptoms, such as loss of control of BF, urgency of BF, urgency of urination, and level of interest/satisfaction in sex. Compared to our earlier study on patients being treated with radiotherapy for PCa, this study produced very similar results. With some modification, the same questionnaire could be used for both groups of patients. Int. J. Cancer (Radiat. Oncol. Invest.) 90, 163-172 (2000).

Quality-of-life outcomes in long-term survivors of advanced prostate cancer.

The authors evaluate the temporal progression of health-related quality of life (HRQOL) in men treated hormonally with surgical or medical castration, as well as to see if either treatment would be associated with a greater impact on patients' quality of life. The authors assessed general and prostate-targeted HRQOL with two self-administered, validated instruments (the RAND 36-Item Health Survey and the UCLA Prostate Cancer Index) in a longitudinal, observational study of 63 men newly diagnosed with metastatic prostate cancer and treated with bilateral orchiectomy or combined androgen blockade with leuprolide and flutamide. Patients completed the two HRQOL instruments by mail at baseline and at 3- and 6-month intervals after initiation of treatment. Significant improvements were demonstrated in 10 of 14 HRQOL domains for all men during the first 12 months. These include all eight of the general HRQOL domains and the disease-specific domains that address bowel function. The authors identified no differences in any of the general or prostate-targeted HRQOL domains when comparing men who underwent orchiectomy versus combined androgen blockade. Patients with metastatic prostate cancer can be informed that general and prostate-specific HRQOL will be similar, regardless of whether they choose medical or surgical castration, and that health status will likely remain stable or improve during the initial months of treatment. Physicians must make patients aware of both the quantity and quality of life they can expect with advanced prostate cancer, and must actively involve them in their treatment decisions.
