QUALITY OF LIFE AFTER TREATMENT FOR LOCALIZED PROSTATE CANCER: DIFFERENCES BASED ON TREATMENT MODALITY

Perception of disease, dyadic coping, and the quality of life of oncology patients in the active treatment phase and their life partners: an approach based on the actor-partner interdependence model

Objective

The aim of this study based on the Systemic Transactional Model was to examine the relationship between dyadic coping and (1) disease perception and (2) quality of life of a sample of cancer patients and their life partners.

Method

This cross-sectional study included 138 oncological dyads. The following questionnaires were used: Stress Appraisal Measure, Dyadic Coping Inventory, and European Organisation for Research and Treatment of Cancer QLQ-C30. Data collected was analysed by applying the actor-partner interdependence model.

Results

The perception of the disease as a threat as well as its centrality significantly negatively influences the positive forms of dyadic coping whilst the perception of the disease as a challenge has a significant positive influence on them. Dyadic coping does not influence symptoms but has significant influences on global health/quality of life.

Conclusion

This study has highlighted new information regarding how couples cope with cancer. The results encourage the inclusion of the perception of the disease and dyadic coping in interventions that aim to improve the quality of life of cancer patients and their life partners.

Decision aids for breast cancer screening in women approximately 50 years of age: A systematic review and meta-analysis of randomised controlled trials

AIMS AND OBJECTIVES

Review the content, quality and effect of breast cancer screening decision aids (BCS-DAs) in women approximately 50 years of age to provide a basis for the development of DAs.

BACKGROUND

Breast cancer screening (BCS) decisions are complex and should vary depending on a woman's risk of breast cancer and her values and preferences. Decision aids (DAs) can help support women and medical staff in shared decision-making (SDM) when solving BCS problems.

DESIGN

Systematic review and meta-analysis.

METHODS

Four databases were searched starting at the time of establishment of the database to March 2021. The PRISMA checklist was followed. The meta-analysis was carried out using Review Manager 5.3 software. The quality of the studies was assessed using the risk of bias tool recommended by the Cochrane Handbook. The quality of the DAs was assessed using the International Standards for Decision Aid (IPDASi v4.0).

RESULTS

The search strategy obtained 2024 references. After abstraction and full text screening, a total of seven studies were included. This article systematically reviews the content, quality and effectiveness of DAs in seven RCTs in helping women to make BCS decisions. The DAs were mostly in paper or online form and displayed disease screening information, analysed the benefits and harms of options and clarified the value to patients. Among all the DAs, only one met the minimum quality standards of IPDASi v4.0. Comprehensive analysis shows that DAs can significantly improve knowledge and increase the proportion of women who make informed choices, but they have no effect on screening attitude, intention, decision conflict or regret.

CONCLUSIONS

In the future, nurses should be encouraged to develop DAs in accordance with strict standards and to make them applicable to young women of different backgrounds.

RELEVANCE TO CLINICAL PRACTICE

The result may be provide a basis for the development of DAs to promote women's informed screening choices.

Can patients with low-risk prostate cancer really benefit from radical treatment?: A systematic review and network meta-analysis

Radical prostatectomy, radiotherapy and active surveillance are three widely used treatment options for patients with low-risk prostate cancer, but the relative effects are controversial. We searched PubMed, Embase and Web of Science until June 2020, focusing on the studies comparing the effect of radical prostatectomy, radiotherapy and active surveillance in patients with low-risk prostate cancer. Through the random-effects model, dichotomous data were extracted and summarised by odds ratio with a 95% confidence interval. Twenty-two studies containing 185,363 participants were pooled for the comprehensive comparison. The Bayesian mixed network estimate demonstrated the cancer-specific mortality of radical prostatectomy was significantly lower than active surveillance (OR, 0.46; 95% CI 0.34-0.64) and external beam radiation therapy (OR, 0.66; 95% CI 0.46-0.96), but not brachytherapy (OR, 0.63; 95% CI 0.41-1.03). The brachytherapy demonstrated the best treatment ranking probability results in terms of all-cause mortality, while no significant difference was observed when compared with other three treatment modalities. Brachytherapy and radical prostatectomy were associated with a similar risk of cancer-specific mortality, and both of them were significantly superior to active surveillance and external beam radiation therapy; nevertheless, there was no significant difference among the aforementioned treatment methods in all-cause mortality.

Relationship communication and the course of psychological outcomes among couples coping with localised prostate cancer

OBJECTIVE

How couples communicate about cancer is an important predictor of psychological outcomes for men diagnosed with localised prostate cancer and their spouses. We examined the predictive role of disclosure, responsiveness, mutual avoidance, and holding back on depressive symptoms, psychological adjustment, cancer-specific distress, and cancer concerns.

METHODS

Eighty-one prostate cancer patients and their spouses completed measures of communication at baseline and measures of four psychological outcomes at baseline, five, 12, and 26 weeks after baseline. Dyadic growth models tested the effects of time and role on each outcome over time.

RESULTS

Higher disclosure and responsiveness predicted better psychological outcomes. Less mutual avoidance and holding back predicted poorer psychological outcomes. Across communication variables, individuals who engaged in poorer communication initially had poorer psychological outcomes that improved over time, whereas individuals who engaged in better communication initially maintained their more positive standing without change or changed in the positive direction. For all outcomes, those with better communication still had better psychological outcomes at six months.

CONCLUSION

Couples' cancer-specific relationship communication predicts their psychological outcomes. More research is needed to identify effective interventions, including a longer therapy course, individual communication training, or greater focus on addressing barriers to sharing and responsiveness.

Perception of disease, dyadic coping and the quality of life of oncology patients in the active treatment phase and their life partners: Study protocol of an approach based on the actor-partner interdependence model

OBJECTIVES

Coping with cancer is a challenge for both patients and their life partners. Although there is evidence in the literature that supports the patient/partner mutual influence at the level of various psychological variables, it is still limited. This study, based on the Systemic Transactional Model, aims to investigate: 1) how the perception of disease of patients and their life partners influences their own dyadic coping and that of the other member of the couple; 2) the influence of the dyadic coping of patients and their partners on the quality of their own life and that of the other member of the couple.

METHODOLOGY

This cross-sectional study aims to recruit 131 dyads consisting of oncology patients in the active treatment phase and their life partners. Perception of disease, dyadic coping and quality of life will be evaluated for each participant. The collected data will be analysed by applying the actor-partner interdependence model (APIM).

CONCLUSION

The results highlighted in this study have the potential to help define future couple interventions that aim to improve quality of life of those facing cancer.

Examining the association of health literacy and numeracy with prostate-related knowledge and prostate cancer treatment regret

INTRODUCTION

Educational materials used in prostate cancer shared decision-making are often written above the health literacy levels of the patients that may benefit the most from such tools. Poor understanding the oncologic and functional outcomes of prostate cancer treatment may influence patient regret during this process. In this study, we assess the association between health literacy, numeracy, prostate-related knowledge and treatment regret in a diverse population.

MATERIALS AND METHODS

Patients obtaining care between June and August of 2016 at both community-based and academic tertiary care facilities were assessed for health literacy and numeracy using validated instruments. Prostate knowledge was tested in those patients without a history of prostate cancer using a 29-item questionnaire and patient-level predictors of knowledge were assessed. Prostate cancer treatment regret was assessed in those patients who had a history of prostate cancer.

RESULTS

A total of 90 patients were enrolled, 38 (42%) of whom had a history of prostate cancer. African American race (I = 0.039), financial strain (P < 0.001), and educational attainment (P < 0.001) were all associated with lower health literacy on multivariable analysis. Possessing a professional degree (P = 0.021) and higher health literacy (P = 0.001) were associated with greater prostate-related knowledge. Of those with a history of prostate cancer, 9 (24%) expressed treatment regret. Patients with regret were more likely to be African American (n = 6, 66.7% vs. 5, 17.2%, P = 0.004), not married (P = 0.016), and score lower on the literacy (1.0 vs. 8.0, P = 0.009) and numeracy (10.0 vs. 16.0, P = 0.016) scales.

CONCLUSIONS

We identified lower health literacy among African American men, and lower prostate-related knowledge in those with poor health literacy. To our knowledge, this is the first study to show an association between health literacy and prostate cancer treatment regret.

Health Related Quality of Life in Japanese Patients with Localized Prostate Cancer: Comparative Retrospective Study of Robot-Assisted Laparoscopic Radical Prostatectomy Versus Radiation Therapy

Background

Radical prostatectomy and radiotherapy are standard treatments for localized prostate cancer. When making decisions about treatment, it is important to not only consider medical information such as the patient's age, performance status, and complications, but also the impact on quality of life (QOL) after treatment.

Our purpose was to compare health related quality of life (HRQOL) after robot-assisted laparoscopic radical prostatectomy (RARP) versus radiation therapy in Japanese patients with localized prostate cancer retrospectively.

Methods

Patients with localized prostate cancer receiving RARP or radiotherapy at Tottori University Hospital between October 2010 and December 2014 were enrolled in a retrospective observational study with follow-up for 24 months to December 2016. The Medical Outcome Study 8-Item Short-Form Health Survey was performed before treatment and 1, 3, 6, 12, and 24 months post-treatment.

Results

Complete responses to the questionnaire were obtained from 154/227 patients receiving RARP, 41/67 patients receiving intensity-modulated radiation therapy, 35/82 patients receiving low dose rate brachytherapy, and 18/28 patients given low dose rate brachytherapy plus external beam radiation therapy. The median physical component summary score of the Medical Outcome Study 8-Item Short-Form Health Survey was significantly lower at 1 month after prostatectomy than radiotherapy, but was similar for both treatments at 3 months, and was significantly higher at 6, 12 and 24 months after prostatectomy. The median mental component summary score was also significantly lower in the prostatectomy group at 1 month, but not from 3 months onwards.

Conclusion

Our study suggested that HRQOL was inferior at 1 month after RARP, however, recovered at 3 months after RARP and was better than after radiotherapy at 6, 12, and 24 months.

The impact of cancer type, treatment, and distress on health-related quality of life: cross-sectional findings from a study of Australian cancer patients

PURPOSE

This study examined the mediating effects of cancer type, treatment, and distress on health-related quality of life (HRQoL) for early diagnosis cancer patients. Results were interpreted with respect to established thresholds for clinical meaningfulness.

METHODS

A cross-sectional design was used. Patients completed surveys collecting demographics, cancer type, treatment, comorbid conditions, distress (HADS), and HRQoL (FACT-G). Hierarchical multivariate regressions examined associations between cancer type, treatment, and distress on HRQoL. Established minimum differences were used to identify clinically meaningful changes in HRQoL.

RESULTS

Of the 1183 patients surveyed, 21% were classified as having elevated anxiety and 13% had elevated depression. Our sample reported significantly lower physical and emotional well-being compared to population norms. Patients with prostate, melanoma, gynaecological, and urological cancers had higher HRQoL scores than those with colorectal cancer. However, when effects for treatment type and distress were considered, differences between cancer types became non-significant. Anxiety and depression were associated with lower HRQoL scores as was chemotherapy. Only depression, anxiety, and chemotherapy were associated with clinically meaningful decreases in HRQoL scores.

CONCLUSIONS

While statistically significant differences in HRQoL were found between different cancer types, only chemotherapy, anxiety, and depression produced clinically meaningful poorer HRQoL scores. In practice, clinically meaningful differences could promote a shift in resources toward interventions where a positive effect on patient well-being is appreciated by both the patient and health professional.

Treatment Decision Regret Among Long-Term Survivors of Localized Prostate Cancer: Results From the Prostate Cancer Outcomes Study

Purpose To determine the demographic, clinical, decision-making, and quality-of-life factors that are associated with treatment decision regret among long-term survivors of localized prostate cancer. Patients and Methods We evaluated men who were age ≤ 75 years when diagnosed with localized prostate cancer between October 1994 and October 1995 in one of six SEER tumor registries and who completed a 15-year follow-up survey. The survey obtained demographic, socioeconomic, and clinical data and measured treatment decision regret, informed decision making, general- and disease-specific quality of life, health worry, prostate-specific antigen (PSA) concern, and outlook on life. We used multivariable logistic regression analyses to identify factors associated with regret. Results We surveyed 934 participants, 69.3% of known survivors. Among the cohort, 59.1% had low-risk tumor characteristics (PSA < 10 ng/mL and Gleason score < 7), and 89.2% underwent active treatment. Overall, 14.6% expressed treatment decision regret: 8.2% of those whose disease was managed conservatively, 15.0% of those who received surgery, and 16.6% of those who underwent radiotherapy. Factors associated with regret on multivariable analysis included reporting moderate or big sexual function bother (reported by 39.0%; OR, 2.77; 95% CI, 1.51 to 5.0), moderate or big bowel function bother (reported by 7.7%; OR, 2.32; 95% CI, 1.04 to 5.15), and PSA concern (mean score 52.8; OR, 1.01 per point change; 95% CI, 1.00 to 1.02). Increasing age at diagnosis and report of having made an informed treatment decision were inversely associated with regret. Conclusion Regret was a relatively infrequently reported outcome among long-term survivors of localized prostate cancer; however, our results suggest that better informing men about treatment options, in particular, conservative treatment, might help mitigate long-term regret. These findings are timely for men with low-risk cancers who are being encouraged to consider active surveillance.

Data Pooling and Analysis to Build a Preliminary Item Bank

Assessing bowel function (BF) in prostate cancer can help determine therapeutic trade-offs. We determined the components of BF commonly assessed in prostate cancer studies as an initial step in creating an item bank for clinical and research application. We analyzed six archived data sets representing 4,246 men with prostate cancer. Thirty-one items from validated instruments were available for analysis. Items were classified into domains (diarrhea, rectal urgency, pain, bleeding, bother/distress, and other) then subjected to conventional psychometric and item response theory (IRT) analyses. Items fit the IRT model if the ratio between observed and expected item variance was between 0.60 and 1.40. Four of 31 items had inadequate fit in at least one analysis. Poorly fitting items included bleeding (2), rectal urgency (1), and bother/distress (1). A fifth item assessing hemorrhoids was poorly correlated with other items. Our analyses supported four related components of BF: diarrhea, rectal urgency, pain, and bother/distress.

Does a decision aid for prostate cancer affect different aspects of decisional regret, assessed with new regret scales? A randomized, controlled trial

OBJECTIVE

To develop and validate new regret scales and examine whether a decision aid affects different aspects of regret in the treatment choice for prostate cancer.

METHODS

This was a multicentre trial (three sites) with imbalanced randomization (1 : 2). From 2008 to 2011, patients with localized prostate cancer were randomized 1 : 2 to usual care (N = 77) or usual care plus a decision aid presenting risks and benefits of different treatments (N = 163). The treatments were surgery and (external or interstitial) radiotherapy. Regret was assessed before, and 6 and 12 months after treatment, using the Decisional regret scale by Brehaut et al. (Medical Decision Making, 23, 2003, 281), and three new scales focusing on process, option and outcome regret. The relation between decision aid and regret was analysed by anova.

RESULTS

The concurrent validity of the new regret scales was confirmed by correlations between regret and anxiety, depression, decision evaluation scales and health-related quality of life. With a decision aid, patient participation was increased (P = 0.002), but regret was not. If anything, in patients with serious morbidity the decision aid resulted in a trend to less option regret and less Brehaut regret (P = 0.075 and P = 0.061, with effect sizes of 0.35 and 0.38, respectively). Exploratory analyses suggest that high-risk patients benefitted most from the decision aid.

CONCLUSION

The new regret scales may be of value in distinguishing separate aspects of regret. In general, regret was not affected by the decision aid. In patients with serious morbidity, a trend to lower option regret with a decision aid was observed.

The association between race and treatment regret among men with recurrent prostate cancer

BACKGROUND

To examine the impact of race on treatment regret among men with recurrent prostate cancer after surgery or radiation.

METHODS

The prospective Comprehensive, Observational, Multicenter, Prostate Adenocarcinoma (COMPARE) registry was used to study a cohort of 484 men with biochemically recurrent prostate cancer after radical prostatectomy, external beam radiation or brachytherapy. Multivariable logistic regression was used to model the association between race and treatment regret and to determine whether there was an interaction between race and sexual problems after treatment with regards to treatment regret.

RESULTS

Black men (N=78) were significantly more likely to have treatment regret when compared with non-black men (N=406; 21.8% versus 12.6%) on univariable analysis (odds ratio (OR) 1.94; 95% confidence interval 1.05-3.56; P=0.03). On multivariable analysis, black race trended towards but was no longer significantly associated with an increase in treatment regret (adjusted OR (AOR) 1.84 (0.95-3.58); P=0.071). There was an interaction between race and sexual problems after treatment (Pinteraction=0.02) such that among those without sexual problems, black men had more treatment regret than non-black men (26.7% versus 8.4%: AOR 4.68 (1.73-12.63); P=0.002), whereas among those with sexual problems, there was no difference in treatment regret between black and non-black men (18.8% versus 17.3%: AOR 1.04 (0.44-2.46); P=0.93).

CONCLUSIONS

Among men with recurrent prostate cancer after surgery or radiation, black men were nearly twice as likely to experience treatment regret. Treating physicians should ensure that patients are fully apprised of the pros and cons of all treatment options to reduce the risk of subsequent regret.

Changes in quality of life among prostate cancer patients after surgery

BACKGROUND

Quality of life (QoL) often is impacted after radical prostatectomy (RP) procedures. Although patients' QoL scores gradually improve after RP, changes in the QoL score over time after different RP procedures must be examined.

OBJECTIVE

The aim of this study was to compare the changes in QoL over time of prostate cancer patients who were treated with open RP (ORP) or laparoscopic RP (LRP) procedures.

METHODS

A longitudinal study design was used. A convenient sample of 67 prostate cancer patients was recruited after RP (ORP = 34, LRP = 33). QoL scores were assessed at 1, 3, and 6 months after RP using the University of California, Los Angeles, Prostate Cancer Index (UCLA-PCI).

RESULTS

With respect to the PCI mean score between the ORP and LRP groups, there were significant differences in overall PCI and urinary function at time 1 (1 month after RP). However, a mixed-design analysis of covariance on the overall PCI of the 2 groups over time indicated that, after controlling for nerve sparing, there were significant differences in the main effects for group and time, but no interaction effect.

CONCLUSION

Results indicated that all patients' QoL scores improved over time. Laparoscopic RP patients' overall scores were better than ORP patients' scores, but this may be due to unmeasured preoperative differences in this nonrandom sample, and thus, these findings cannot be attributed to treatment differences alone.

IMPLICATIONS FOR PRACTICE

Patients' QoL after either RP surgery is likely to drop but is regained by 6 months. This information should be given to patients undergoing RP who are deciding between various RP procedures.

Prospective longitudinal comparative study of health-related quality of life and treatment satisfaction in patients treated with hormone therapy, radical retropubic prostatectomy, and high or low dose rate brachytherapy for prostate cancer

PURPOSE

To evaluate the effects of four different prostate cancer treatments on quality of life (QoL) and patient satisfaction.

METHODS

Ninety-six prostate cancer patients were treated with hormone therapy, radical retropubic prostatectomy, high dose rate brachytherapy, or low dose rate brachytherapy. We assessed general, cancer-specific, and prostate disease-specific QoL. More than one year since commencement of treatment, the patients were asked the following questions: 1) How do you feel about your treatment? 2) Would you undergo the same treatment again?

RESULTS

The comparison of baseline and 12-month results showed that general and cancer-specific QoL had changed little in all groups. At baseline, the general and cancer-specific QoL tended to be lower in the hormone therapy patients. In the radical the retropubic prostatectomy patients, all scores on the Medical Outcomes Study 36-Item Short Form were worse than the baseline scores at three months. Scores for the International Index of Erectile Function-5 had also worsened, with no recovery. In the low-dose rate brachytherapy patients, the prostate disease-specific QoL at baseline tended to improve. However, the satisfaction levels for each treatment were reasonably good, and most patients would choose the same treatment again.

CONCLUSIONS

The results of each of the four treatments differed in assessments of QoL. In the radical retropubic prostatectomy patients, the decrease in the International Index of Erectile Function-5 scores was especially remarkable and did not show recovery. In contrast, both brachy therapy groups had attained superior sexual function. However, regardless of the quality of life evaluations, most patients surveyed were satisfied with their treatments and would choose the same treatment again.

Impact of prostate size on urinary quality of life scores after open radical prostatectomy: a single-center experience

OBJECTIVE

The aim of this study was to assess the effects of prostate size on long-term health-related quality of life (HRQoL) and functional outcomes after radical prostatectomy (RP).

MATERIAL AND METHODS

A total of 207 consecutive patients who underwent RP for localized prostate cancer was stratified by pathological prostate gland weight into group 1, patients with prostate glands weighing less than 30 g; group 2, those with prostates weighing 30-50 g; and group 3, those with prostates weighing more than 50 g. Urinary HRQoL was assessed before surgery and at 1, 3, 6, 12, 18, 24, 36, 48 and 60 months after RP using a Japanese version of the Expanded Prostate Cancer Index Composite (EPIC) questionnaire.

RESULTS

Baseline urinary function was significantly (p < 0.05) reduced in patients with the largest glands (group 3), as demonstrated by EPIC urinary domain summary and subscale scores, including scores for urinary bother, irritation and obstruction, compared with patients with smaller glands (groups 1 and 2). At follow-up ranging from 18 to 36 months, patients in group 3 had improved EPIC urinary domain summary and subscale scores, including scores for urinary irritation and obstruction and urinary bother subscale scores, compared with their baseline scores (p < 0.05).

CONCLUSIONS

In patients with large prostate glands, postoperative improvement was observed in HRQoL and functional outcome after RP. Thus, RP may be beneficial in patients with large prostates.

A randomised, wait-list controlled trial: evaluation of a cognitive-behavioural group intervention on psycho-sexual adjustment for men with localised prostate cancer

OBJECTIVE

To examine the effectiveness of a cognitive-behavioural therapy (CBT) group intervention to facilitate improved psycho-sexual adjustment to treatment side effects in prostate cancer survivors post-radical prostatectomy.

METHODS

A randomised, wait-list controlled trial was conducted with a total of 60 men who participated in a manualised 8-week cognitive-behavioural group intervention 6 months to 5 years post-radical prostatectomy for localised prostate cancer. Participants completed standardised questionnaires pre-intervention and post-intervention, which assessed mood state, stress, general and prostate cancer anxiety, quality of life and areas of sexual functioning.

RESULTS

Paired samples t-tests identified a significant improvement in sexual confidence, masculine self-esteem, sexual drive/relationship and a significant decline in sexual behaviour from pre-intervention to post-intervention. Hierarchical regression analyses revealed that after controlling for covariates, participation in the group intervention significantly improved sexual confidence, sexual intimacy, masculine self-esteem and satisfaction with orgasm.

CONCLUSIONS

This group-based CBT intervention for men post-radical prostatectomy for localised prostate cancer shows promising results in terms of improving quality of life.

Cardiovascular comorbidity and treatment regret in men with recurrent prostate cancer

Study Type - Therapy (case series). Level of Evidence 4. What's known on the subject? and What does the study add? Treatment regret can have an adverse impact on a patient's overall outlook and has been associated with a poorer global quality of life. Understanding predictors of regret can help clinicians better counsel patients about their treatments so that later regret can be avoided. In previous studies, regret has been associated with lesser educational attainment, non-White race, greater post-treatment declines in sexual function and systemic symptoms. The present study found that, among men with recurrent prostate cancer, those with cardiovascular comorbidity were >50% more likely to regret their treatment choice than men without cardiovascular comorbidity. This study highlights the growing importance of considering comorbidity when counselling patients about prostate cancer treatment options, and provides a rationale for men with cardiovascular comorbidity to give additional consideration to active surveillance for their newly diagnosed prostate cancer.

OBJECTIVE

• To determine whether cardiovascular comorbidity is associated with increased treatment regret among men with recurrent prostate cancer.

METHODS

• The study cohort comprised 795 men in the Comprehensive, Observational, Multicenter, Prostate Adenocarcinoma (COMPARE) registry who experienced biochemical recurrence at a median (interquartile range) of 5.5 (2.8-9.1) years after prostatectomy (n= 410), external beam radiation therapy (n= 237), brachytherapy (n= 124) or primary androgen deprivation therapy (n= 24). • Multivariable logistic regression analysis was used to determine whether cardiovascular comorbidity was associated with treatment regret. • Cardiovascular comorbidity, which included myocardial infarction, congestive heart failure, angina, diabetes, stroke or circulation problems, was defined using a validated two-question screening process after adjusting for sociodemographic and treatment factors and post-treatment bladder and bowel toxicity.

RESULTS

• Of 795 men, 14.8% reported regret. • Men with cardiovascular comorbidity were more likely to experience post-therapy bowel toxicity (P= 0.022). • In the adjusted multivariable model, the factors associated with increased treatment regret were: cardiovascular comorbidity (adjusted odds ratio [AOR]= 1.52 [95% CI:1.00-2.31], P= 0.048); younger age (AOR: 0.97 [95% CI 0.94-0.99] per year increase in age, P= 0.019); and bowel toxicity after treatment (AOR 1.58 [95% CI 1.03-2.43], P= 0.038).

CONCLUSIONS

• Among men with recurrent prostate cancer, those with cardiovascular comorbidity were >50% more likely to experience treatment regret than men without cardiovascular comorbidity. • These data provide a rationale for men with cardiovascular comorbidity to give additional consideration to active surveillance for their newly diagnosed prostate cancer.

Low-dose rate brachytherapy for men with localized prostate cancer

BACKGROUND

Localized prostate cancer is a slow growing tumor for many years for the majority of affected men. Low-dose rate brachytherapy (LDR-BT) is short-distance radiotherapy using low-energy radioactive sources. LDR-BT has been recommended for men with low risk localized prostate cancer.

OBJECTIVES

To assess the benefit and harm of LDR-BT compared to radical prostatectomy (RP), external beam radiotherapy (EBRT), and no primary therapy (NPT) in men with localized prostatic cancer.

SEARCH STRATEGY

The Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (from 1950), and EMBASE (from 1980) were searched in June 2010 as well as online trials registers and reference lists of reviews.

SELECTION CRITERIA

Randomized, controlled trials comparing LDR-BT versus RP, EBRT, and NPT in men with clinically localized prostate cancer.

DATA COLLECTION AND ANALYSIS

Data on study methods, participants, treatment regimens, observation period and outcomes were recorded by two reviewers independently.

MAIN RESULTS

We identified only one RCT (N = 200; mean follow up 68 months). This trial compared LDR-BT and RP. The risk of bias was deemed high. Primary outcomes (overall survival, cause-specific mortality, or metastatic-free survival) were not reported. Biochemical recurrence-free survival at 5 years follow up was not significantly different between LDR-BT (78/85 (91.8%)) and RP (81/89 (91.0%)); P = 0.875; relative risk 0.92 (95% CI: 0.35 to 2.42).For severe adverse events reported at 6 months follow up, results favored LDR-BT for urinary incontinence (LDR-BT 0/85 (0.0%) versus RP 16/89 (18.0%); P < 0.001; relative risk 0) and favored RP for urinary irritation (LDR-BT 68/85 (80.0%) versus RP 4/89 (4.5%); P < 0.001; relative risk 17.80, 95% CI 6.79 to 46.66). The occurrence of urinary stricture did not significantly differ between the treatment groups (LDR-BT 2/85 (2.4%) versus RP 6/89 (6.7%); P = 0.221; relative risk 0.35, 95% CI: 0.07 to 1.68). Long-term information was not available.We did not identify significant differences of mean scores between treatment groups for patient-reported outcomes function and bother as well as generic health-related quality of life.

AUTHORS' CONCLUSIONS

Low-dose rate brachytherapy did not reduce biochemical recurrence-free survival versus radical prostatectomy at 5 years. For short-term severe adverse events, low-dose rate brachytherapy was significantly more favorable for urinary incontinence, but radical prostatectomy was significantly more favorable for urinary irritation. Evidence is based on one RCT with high risk of bias.

Permanent interstitial low-dose-rate brachytherapy for patients with localised prostate cancer: a systematic review of randomised and nonrandomised controlled clinical trials

CONTEXT

Prostate cancer (PCa) is the most common cancer in men. Permanent interstitial low-dose-rate brachytherapy (LDR-BT) is a short-distance radiation therapy in which low-energy radioactive sources are implanted permanently into the prostate.

OBJECTIVE

To assess the effectiveness and safety of LDR-BT compared to treatment alternatives in men with localised PCa.

EVIDENCE ACQUISITION

Bibliographic databases (Medline, Embase, and the Cochrane Library) were searched from inception until June 2010 for randomised and nonrandomised controlled trials comparing LDR-BT with radical prostatectomy (RP), external-beam radiation therapy (EBRT), or no primary therapy (NPT). Primary outcome was overall survival (OS). Secondary outcomes were disease-free survival (DFS), biochemical recurrence-free survival (bRFS), physician-reported severe adverse events (SAE), and patient-reported outcomes (PRO).

EVIDENCE SYNTHESIS

A total of 31 studies, including 1 randomised controlled trial (RCT), were identified. Risk of bias was high for all 31 studies. OS was reported in one nonrandomised controlled study; however, these data were not interpretable because of strong residual confounding. DFS was not reported. Comparison of bRFS between treatment groups is not validated; thus, results were not interpretable. Physician-reported urogenital late toxicity grade 2 to 3 was more common in the LDR-BT group when compared to the EBRT group. With respect to PRO, better scores for sexual and urinary function as well as urinary incontinence were reported for LDR-BT compared to RP. Better scores for bowel function were reported for LDR-BT compared to EBRT.

CONCLUSIONS

We found a low amount of evidence in studies that exclusively compared LDR-BT with other treatment modalities. LDR-BT may have some different physician-reported SAE and patient-reported outcomes. The current evidence is insufficient to allow a definitive conclusion about OS. Randomised trials focusing on long-term survival are needed to clarify the relevance of LDR-BT in patients with localised PCa.

Comparison of Health-Related Quality of Life 5 Years After SPIRIT: Surgical Prostatectomy Versus Interstitial Radiation Intervention Trial

Purpose

The American College of Surgeons Oncology Group phase III Surgical Prostatectomy Versus Interstitial Radiation Intervention Trial comparing radical prostatectomy (RP) and brachytherapy (BT) closed after 2 years due to poor accrual. We report health-related quality of life (HRQOL) at a mean of 5.3 years for 168 trial-eligible men who either chose or were randomly assigned to RP or BT following a multidisciplinary educational session.

Patients and Methods

After initial lack of accrual, a multidisciplinary educational session was introduced for eligible patients. In all, 263 men attended 47 sessions. Of those, 34 consented to random assignment, 62 chose RP, and 94 chose BT. Five years later, these 190 men underwent HRQOL evaluation by using the cancer-specific 50-item Expanded Prostate Cancer Index Composite, the Short Form 12 Physical Component Score, and Short Form 12 Mental Component Score. Response rate was 88.4%. The Wilcoxon rank sum test was used to compare summary scores between the two interventions.

Results

Of 168 survey responders, 60.7% had BT (9.5% randomly assigned) and 39.3% had RP (9.5% randomly assigned). Median age was 61.4 years for BT and 59.4 for RP (P = .05). Median follow-up was 5.2 years (range, 3.2 to 6.5 years). For BT versus RP, there was no difference in bowel or hormonal domains, but men treated with BT scored better in urinary (91.8 v 88.1; P = .02) and sexual (52.5 v 39.2; P = .001) domains, and in patient satisfaction (93.6 v 76.9; P < .001).

Conclusion

Although treatment allocation was random in only 19%, all patients received identical information in a multidisciplinary setting before selecting RP, BT, or random assignment. HRQOL evaluated 3.2 to 6.5 years after treatment showed an advantage for BT in urinary and sexual domains and in patient satisfaction.

Early prostate cancer--which treatment do men prefer and why?

STUDY TYPE

Preference (prospective cohort).

LEVEL OF EVIDENCE

1b. What's known on the subject? and What does the study add? In general the literature suggests that there is a need for improvement in aiding men diagnosed with early prostate cancer in their decision making about treatment options and that our understanding of this process is inadequate. There is limited data analyzing the reasons why these men decide between potentially curative or observational treatments and data evaluating patients' views before and after definitive therapy are scarce. This study begins the process of understanding the reasons underlying a patient's final treatment decision. Being a prospective study, it looks at the thought processes of these men before treatment during the time the decision is made. It also documents how satisfied patients are with their choice after their treatment and whether they would choose the same treatment again.

OBJECTIVE

To identify the reasons for patients with localised prostate cancer choosing between treatments and the relationship of procedure type to patient satisfaction post-treatment.

PATIENTS AND METHODS

768 men with prostate cancer (stage T1/2, Gleason≤7, PSA<20 ug/L) chose between four treatments: radical prostatectomy, brachytherapy, conformal radiotherapy and active surveillance. Prior to choosing, patients were counselled by a urological surgeon, clinical (radiation) oncologist and uro-oncology specialist nurse. Pre-treatment reasons for choice were recorded. Post-treatment satisfaction was examined via postal questionnaire.

RESULTS

Of the 768 patients, 305 (40%) chose surgery, 237 (31%) conformal beam radiotherapy, 165 (21%) brachytherapy and 61 (8%) active surveillance. Sixty percent of men who opted for radical prostatectomy were motivated by the need for physical removal of the cancer. Conformal radiotherapy was mainly chosen by patients who feared other treatments (n=63, 27%). Most men chose brachytherapy because it was more convenient for their lifestyle (n=64, 39%). Active surveillance was chosen by patients for more varied reasons. Post-treatment satisfaction was assessed in a subgroup who took part in the QOL aspect of this study. Of the respondents to the questionnaire, 212(87.6%) stated that they were satisfied/extremely satisfied with their choice and 171(92.9%) indicated they would choose the same treatment again.

CONCLUSION

Men with early prostate cancer have clear reasons for making decisions about treatment. Overall, patients were satisfied with the treatment and indicated that despite different reasons for choosing treatment, they would make the same choice again.

Short- and long-term HRQOL issues following brachytherapy for prostate cancer

Given the lack of evidence from randomized controlled trials and large prospective studies, controversy exists regarding the optimal treatment strategy for early stage prostate cancer. The impact of various treatments on health-related quality of life has become an increasingly important but controversial issue. The literature on health-related quality of life following brachytherapy, an increasingly used treatment option that can have short- and long-term side effects influencing patient health-related quality of life is reviewed. Urinary, bowel and sexual health-related quality of life issues related to this treatment are addressed. The authors findings suggest that brachytherapy with or without external beam radiotherapy and/or hormonal treatment has a considerable impact on short-term health-related quality of life but this impact diminishes in the long-term. However, in certain subgroups of patients, brachytherapy has long-term effects on bowel, bladder and sexual function. Clinicians should ensure that patients are aware of these consequences on long-term health-related quality of life.

Quality of life two years after radical prostatectomy, prostate brachytherapy or external beam radiotherapy for clinically localised prostate cancer: the Catalan Institute of Oncology/Bellvitge Hospital experience

OBJECTIVE

The objective was to compare the short- and long-term impact of 3 different treatment modalities on health-related quality of life (HRQOL) in patients treated for localised prostate cancer at a single centre in Catalonia, Spain.

MATERIAL AND METHODS

This was a longitudinal, prospective study of 304 patients from a single centre in Catalonia, Spain. Patients underwent 1 of 3 treatment procedures: radical prostatectomy (114 patients), external beam radiation (134) or interstitial brachytherapy (56). HRQOL was assessed by both general and specific questionnaires, including the SF-36 health survey and the Expanded Prostate Cancer Index Composite (EPIC). Interviews were administered prior to treatment and at months 1, 3, 6, 12 and 24. One-way analysis of variance and generalised estimating equations models were constructed to assess between group differences in HRQOL.

RESULTS

After initial deterioration, HRQOL scores partially recovered, although significant differences between treatment groups persisted at two years. Worsening of urinary incontinence was especially marked for the radical prostatectomy group (11.45, p=0.005), while deterioration in the urinary irritative/obstructive domain was worse following brachytherapy treatment (4.76, p=0.025). Decline in sexual function was significantly greater for the radical prostatectomy group than for the brachytherapy group (18.74, p<0.001). No significant between-group differences were observed in bowel domain scores.

CONCLUSIONS

Quality of life 2 years after treatment for prostate cancer shows wide variability. Radical prostatectomy had the largest negative impact on the sexual and urinary incontinence domains. Differences between external radiation and brachytherapy were relatively small. Brachytherapy led to a moderate increase in urinary irritation compared to the other 2 groups.

[Perioperative morbidity of radical prostatectomy in patients over 70 years of age]

INTRODUCTION

Increased life expectancy has made possible radical treatment of localized prostate cancer in patients over 70 years of age. Perioperative morbidity of radical prostatectomy in elderly patients depending on surgical procedure has not been adequately analyzed.

OBJECTIVES

To comparatively analyze the incidence, severity, and management of perioperative complications of retropubic versus laparoscopic radical prostatectomy in patients older than 70 years.

MATERIAL AND METHODS

A retrospective review was made of 68 patients over 70 years of age (of whom 42 underwent retropubic and 26 laparoscopic radical prostatectomy) taken from a series of 500 patients. The modified Clavien classification was used to study complications from both surgical procedures.

RESULTS

The overall complication rate was 59.5% for the retropubic and 23% for the laparoscopic procedure (P=.003). Three grade I, 2 grade Id, 19 grade II, and 1 grade IId complications were seen with retropubic surgery, as compared to 2 grade I and 5 grade Id complications with the laparoscopic procedure. The most common complications included intraoperative bleeding (38%) and urinaryi fistula (15%) respectively.

CONCLUSIONS

Radical prostatectomy is a procedure that is not free from complications in patients older than 70 years, though these are usually mild. The advantages usually attributed to laparoscopy also apply to elderly patients, and should therefore be considered as the procedure of choice.

Utility and health-related quality of life in prostate cancer patients 12 months after radical prostatectomy or radiation therapy

This study aims to examine and compare changes in quality of life after two common treatments for prostate cancer (PC), radical prostatectomy (RP) and radiation therapy (RT). Patients newly diagnosed with localized PC, scheduled to receive RP (n=68) or RT (n=66), completed three cancer/PC-specific psychometric instruments and three PC-specific utility instruments before treatment, and 2 and 12 months after treatment. We assessed the magnitude and time course of changes in psychometric and utility measures, and differences between treatments. The results showed that RP was associated with significant urinary and sexual dysfunction; RT caused bowel problems. Fatigue and pain were common to both. RP patients reported more problems with physical, role and social function. Utilities decreased significantly after both treatments. Effects were most severe 2 months post treatment, and then showed some recovery, but many endured for 1 year. After 1 year, 30-60% of patients had utility scores that were clinically significantly worse than at baseline. Secondary androgen deprivation therapy also significantly decreased psychometric and utility measures of quality of life. Many adverse symptoms reported 2 months after RP and RT endure for 1 year. Despite different symptom profiles, RP and RT result in similar utility decrements.

Reliability of assessment of urgency and other symptoms indicating anal sphincter, large bowel or urinary dysfunction

OBJECTIVE

The Radiumhemmets Scale of Disease-Specific Symptom Assessment-Prostate Cancer has been used in several studies. However, no test-retest reliability study of it has been conducted concerning the assessment of urinary, anal sphincter or large bowel function. The aim of this study was to evaluate the reliability of items assessing these functions.

MATERIAL AND METHODS

We investigated 89 prostate cancer patients randomly selected from a group of patients diagnosed in Stockholm. The patients answered 24 questions assessing anal sphincter, large bowel and urinary function twice, with a 3-week interval in-between, to assess reliability.

RESULTS

Most of the questions assessing bowel and urinary symptoms showed substantial or near-perfect agreement. The kappa value for bowel symptom items was > or = 0.60 for all items, except for defecation urgency (0.40-0.55). The kappa value for urinary symptom items varied between 0.43 and 1.0, except for urinary urgency (0.30-0.39).

CONCLUSIONS

When comparing the impact of different symptoms of anal sphincter, large bowel or urinary tract dysfunction, it may be important to consider that defecation urgency and urinary urgency have the highest measuring error (low reliability). This error dilutes assessed associations with, for example, decreased quality of life. Nevertheless, the test-retest reliability for anal sphincter, large bowel and urinary symptoms indicates that surveys yield meaningful information.

Health-related quality of life using SF-8 and EPIC questionnaires after treatment with radical retropubic prostatectomy and permanent prostate brachytherapy

OBJECTIVE

The health-related quality of life (HRQOL) after treatment of prostate cancer is examined using a new HRQOL tool. HRQOL, based on the expanded prostate cancer index composite (EPIC) and SF-8 questionnaires, was prospectively compared after either a radical retropubic prostatectomy (RRP) or a permanent prostate brachytherapy (PPB) at a single institute.

METHODS

Between October 2005 and June 2007, 96 patients were treated by an RRP and 88 patients were treated by a PPB. A HRQOL survey was completed at baseline, and at 1, 3, 6 and 12 months after treatment, prospectively.

RESULTS

The general HRQOL in the RRP and PPB groups was not different after 3 months. However, at baseline and 1 month after treatment, the mental component summary was significantly better in the PPB group than in the RRP group. Moreover, the disease-specific HRQOL was worse regarding urinary and sexual functions in the RRP group. Urinary irritative/obstructive was worse in the PPB group, but urinary incontinence was worse in the RRP group and had not recovered to baseline after 12 months. The bowel function and bother were worse in the PPB group than in the RRP group after 3 months. In the RRP group, the patients with nerve sparing demonstrated the same scores in sexual function as the PPB group.

CONCLUSIONS

This prospective study revealed the differences in the HRQOL after an RRP and PPB. Disease-specific HRQOL is clarified by using EPIC survey. These results will be helpful for making treatment decisions.

Neoadjuvant hormonal therapy and external-beam radiotherapy versus external-beam irradiation alone for prostate cancer. A quality-of-life analysis

PURPOSE

To evaluate the impact of neoadjuvant hormonal therapy (NHT) on quality of life after external-beam radiotherapy (EBRT) for prostate cancer.

PATIENTS AND METHODS

A group of 170 patients (85 with and 85 without NHT) has been surveyed prospectively before EBRT (70.2-72 Gy), at the last day of EBRT, a median time of 2 months and 15 months after EBRT using a validated questionnaire (Expanded Prostate Cancer Index Composite). Pairs with and without NHT (median treatment time of 3.5 months before EBRT) were matched according to the respective planning target volume and prostate volume.

RESULTS

Before EBRT, significantly lower urinary function/bother, sexual function and hormonal function/bother scores were found for patients with NHT. More than 1 year after EBRT, only sexual function scores remained lower. In a multivariate analysis, NHT and adjuvant hormonal therapy (HT) versus NHT only (hazard ratio 14; 95% confidence interval 2.7-183; p = 0.02) and luteinizing hormone-releasing hormone (LHRH) agonists versus antiandrogens (hazard ratio 3.6; 95% confidence interval 1.1-12; p = 0.04) proved to be independent risk factors for long-term erectile dysfunction (no or very poor ability to have an erection).

CONCLUSION

With the exception of sexual function (additional adjuvant HT and application of LHRH analog independently adverse), short-term NHT was not found to decrease quality of life after EBRT for prostate cancer.

Quality of life after radical prostatectomy in Japanese men: a 5-Year follow up study

OBJECTIVES

To measure health-related quality of life (HRQOL) after radical prostatectomy (RP) in Japanese men with localized prostate cancer.

METHODS

A total of 154 patients who underwent RP were included in this 5-year longitudinal survey. The Short Form 36-Item Health Survey, the University of California, Los Angeles, Prostate Cancer Index and the International Prostate Symptom Score questionnaires were administered at diagnosis and nine times afterwards.

RESULTS

Patients undergoing RP showed problems in some physical domains of general HRQOL, but these problems diminished over time. Mental health and social functions significantly improved during the follow-up period. The urinary function substantially declined at 3 months and continued to recover gradually but never returned to baseline. Most patients (95%) recovered to their baseline urinary bother score within 60 months. The overall mean total International Prostate Symptom Score progressively improved with time. On the other hand, at 60 months after RP, only 34% of subjects had fully returned to baseline sexual function. By 5 years postoperatively, 78% of the men had reached baseline sexual bother and the mean recovery time was 8.6 months. Adverse effects of RP on sexual function and bother were mitigated by bilateral nerve-sparing procedures up to 5 years after the operation.

CONCLUSIONS

Despite reported problems with sexuality and urinary continence, general HRQOL was mostly unaffected by RP after 6 months in our survey with functional outcomes remaining relatively stable in the majority of patients.

[Brachytherapy of the prostate cancer]

Prostate cancer (PCA) is the most frequent onlocological disease in men. Every year there are ca. 202.000 new cases of prostate cancer in Europe. Curative treatment of this carcinoma via brachytherapy is becoming increasingly significant (20-30% of all curative approaches). Initial staging and thus allocation to risk groups prior to the commencement of therapy is esspecially important for successful brachytherapy treatment.Low-dose-rate (LDR) brachytherapy (i.e. SEED implantation) distinguishes itself both with respect to the procedure as well as the indication from high-dose-rate brachytherapy (afterloading procedure). Both treatment procedures are employed as monotherapy as well as in combination with external radiation.LDR monotherapy is reported to achieve biochemically relapse-free outcome of up to 90% in low-risk tumours during 10-year follow-up periods. Combined HDR tele- and brachytherapy is reported to achieve a biochemically relapse-free outcome of 80-90% with intermediate- and high-risk tumours in long-term follow-up.While randomized studies are as yet missing, it is still possible to derive the following application algorithms from monitoring studies and cohort studies: application of LDR monobrachytherapy must be restricted to low-risk tumorus. Combined HDR tele- and brachytherapy can be sucessfully applied in cases of intermediate- and high-risk tumours. The outcome depends significantly on the initial, pre-therapy PSA value and Gleason score. Posttherapeutically, the nadir value is crucial with respect to predicting the biochemically relapse-free outcome.

The effect of erectile function on the use of phosphodiesterase-5 inhibitors after radical prostatectomy in Japanese and U.S. men

OBJECTIVES

To compare patterns of phosphodiesterase-5 (PDE-5) inhibitor use between Japanese and U.S. men after radical prostatectomy.

METHODS

A total of 168 Japanese men and 205 U.S. men with localized prostate cancer who were enrolled in studies of health-related quality-of-life outcomes participated in this study. Sexual function and bother were estimated with validated English and Japanese versions of the University of California-Los Angeles Prostate Cancer Index before and after treatment. Use of PDE-5 inhibitors was self-reported.

RESULTS

During the 24 months after radical prostatectomy, 71.8% of the U.S. men and 10.1% of the Japanese men used PDE-5 inhibitors. Japanese users reported significantly better sexual function than did non-users before (41 versus 29, P = 0.028) and after (31 versus 9, P = 0.040) surgery. In contrast, the U.S. users reported significantly worse sexual function than did non-users before (59 versus 77, P <0.001) and after (33 versus 54, P <0.001) surgery. Postoperative sexual bother did not differ between users and non-users in either group.

CONCLUSIONS

Japanese men were much less likely to use PDE-5 inhibitors than were U.S. men after radical prostatectomy, despite reporting worse sexual function scores. Cultural differences in patterns of PDE-5 inhibitor use after prostatectomy were evident.
