Defining a standard set of patient-centered outcomes for men with localized prostate cancer

Onset and burden of lower limb lymphedema after radical prostatectomy: a cross-sectional study

OBJECTIVES

To explore men's onset and burden of lower limb lymphedema (LLL) after radical prostatectomy (RP) with pelvic lymph node dissection (PLND).

PATIENTS AND METHODS

A cross-sectional survey-based study was conducted nation-wide and web-based in Germany. Part 1 included 15 multidisciplinary compiled questions with three questions from the Short Form 12 Health Survey (SF-12) and the WHO activity recommendation and part 2 included the validated German Lymph-ICF-Questionnaire (Lymph-ICF-LL). Subgroup comparisons and simple regression analyses were used to identify factors associated with therapy and burden of LLL, followed by multiple regression analyses to explain variance in impairment in the patients' daily life.

RESULTS

Fifty-four patients completed the survey. Median time of LLL-onset was reported with 2.0 (0.5-9.75) months after RP. Nineteen patients (35.2%) reported bilateral lymphedema, 28 (51.9%) the use of individually fitted compression stockings (CS), 25 (46.3%) of manual lymphatic drainage (LD), and 26 (48.1%) complete regression. The Lymph-ICF-LL revealed a higher total burden for patients with an active LLL compared to complete regression (total score: 25.5 vs. 11.9, p = 0.01) especially for "physical function" (28.3 vs. 12.9, p < 0.01) and "mental function" (26.2 vs. 6.7, p < 0.01). In multiple linear regression analysis, a higher BMI (β = 0.28), lower subjective general health (β = -0.48), and active lymphedema (β = 0.28) were significant predictors of higher reported impairments in the Lymph-ICF-LL, accounting for 45.4% of variance.

CONCLUSION

Men with LLL after RP with PLND report a significant burden in daily life. Basic therapy needs to be offered early. Postoperative onset of LLL is variable, which should be considered when assessing complications after RP.

The basics of onco-nephrology in the renal clinic

Onconephrology is a rapidly evolving subspecialty that covers all areas of renal involvement in cancer patients. The complexity of the field may benefit from well-defined multidisciplinary management by a dedicated team. Patients with cancer frequently suffer from concurrent chronic kidney disease (CKD), with a prevalence ranging from 12% to 53% at the time of cancer diagnosis. Taking into account the incidence of cancer and the prevalence of CKD in the Italian population, we estimate that about 44,000 patients suffered from both diseases in 2020. Since there is an increasing necessity to address the needs of this population in dedicated outpatient clinics, it is critical to highlight some basic characteristics and to suggest areas of development. Our experience in the nephrological management of cancer patients clearly suggests the need to implement dedicated multidisciplinary teams and to create onconephrology clinics (at least within larger, referral, hospitals). Furthermore, it must be kept in mind that not only is CKD common in cancer patients, but also that the concomitant presence of these two conditions too often excludes cancer patients from clinical trials, thus limiting their access to therapies that could potentially improve their outcomes. Indeed, the Renal Insufficiency and Cancer Medications (IRMA) study found that cancer patients with CKD or on dialysis are often undertreated, or are exposed to either ineffective or toxic anticancer agents. Finally, the aim of this article is to initiate a debate about what an onconephrology outpatient clinic might look like, in order to ensure the highest quality of care for this growing patient population.

Treatment of post-prostatectomy urinary incontinence and erectile dysfunction: there is insufficient utilisation of care in German cancer survivors

PURPOSE

Treatment of post-prostatectomy urinary incontinence (UI) and erectile dysfunction (ED) increases quality of life (QoL). Aim of our study was to evaluate the utilisation of care among patients with post-prostatectomy UI and ED in Germany.

METHODS

The HAROW study documented treatment of patients with localised prostate cancer (≤ T2c) in Germany. 1260 patients underwent radical prostatectomy (RP). Patients answered validated questionnaires after a median follow-up of 6.3 years. Response rate was 76.8%.

RESULTS

Median age at RP was 65 (IQR 60-69) years. 14% (134/936) used more than one pad per day for UI. 25% (26/104, 30 missing) of UI patients underwent surgery to improve continence. Of patients without surgery, 41% (31/75) reported a moderate-to-severe issue concerning their incontinence with worse mental health and QoL. 81% (755/936) patients were unable to have an erection firm enough for sexual intercourse. Of all ED patients, 40% (319/793) used ED treatment regularly or tried it at least once. 49% (243/499) of patients with interest in sex never tried ED treatment. In multivariate analysis, patients not using ED treatments were older (≥ 70 years OR 4.1), and more often had preoperative ED (OR 2.3) and less interest in sex (OR 2.2). Nevertheless, 30% (73/240) of these patients had moderate-to-severe issues with their ED reporting worse mental health and QoL.

CONCLUSION

Almost half of the patients without post-prostatectomy UI and ED treatment reported moderate-to-severe issues with a significant decrease in QoL. This indicates an insufficient utilisation of care in Germany.

Comparative Effectiveness Research in Localized Prostate Cancer: A 10-Year Follow-up Cohort Study

PURPOSE

Long-term comparative effectiveness research on localized prostate cancer treatments is scarce, and evidence is lacking especially for brachytherapy. The aim of this study was to assess the long-term impact of the side effects of radical prostatectomy, brachytherapy, and external radiation therapy on patients with localized prostate cancer at 10 years, using propensity score analyses.

METHODS AND MATERIALS

This was a prospective observational study of a cohort of men who received a diagnosis of clinically localized prostate cancer (clinical stage T1 or T2, low and intermediate risk group) and were treated with radical prostatectomy (n = 139), brachytherapy (n = 317), or external radiation therapy (n = 194). Treatment decisions were jointly made by patients and physicians. Patient-reported outcome (PRO) evaluation included the Expanded Prostate Cancer Index Composite and Short Form-36, administered centrally by telephone interviews before and annually after treatment. The Expanded Prostate Cancer Index Composite covers urinary, bowel, sexual, and hormonal domains. To assess PRO changes over time, while accounting for correlation among repeated measures, generalized estimating equation models adjusted by propensity scores were constructed.

RESULTS

The PRO completion rate at 10 years was 85.8%. Generalized estimating equation models showed that the pattern of radical prostatectomy side effects, with substantial urinary incontinence and sexual dysfunction, remained until 10 years after treatment (standard deviation [SD], -1.1 and -1.3, respectively). Brachytherapy produced late deterioration in urinary continence (SD, -0.4) and sexual function (SD, -0.9) that appeared midterm, but the differences from radical prostatectomy remained statistically significant at 10 years (P < .001 after adjusting by propensity score). External radiation therapy showed similar results to brachytherapy, but with bowel bother (SD, -0.3).

CONCLUSIONS

Although late deterioration in radiation therapy groups attenuated differences from radical prostatectomy, relevant PRO differences still remained after 10 years. Our findings support that brachytherapy is the treatment option that causes the least impact on PROs; it is therefore an alternative to be considered when making evidence-based decisions on localized prostate cancer treatment.

Standard set of patient-reported outcomes for personality disorder

PURPOSE

The purpose of the article is to present standard set of outcomes for people with personality disorder (PD), in order to facilitate patient outcome measurement worldwide.

METHODS

The International Consortium for Health Outcomes Measurement (ICHOM) gathered a multidisciplinary international working group, consisting of 16 experts, including clinicians, nurses, psychologists, methodologists and patient representatives, to develop a standard set of outcome measures for people with PD. The Delphi method was used to reach consensus on the scope of the set, outcome domains, outcome measures, case-mix variables and time points for measuring outcomes in service users. For each phase, a project team prepared materials based on systematic literature reviews and consultations with experts.

RESULTS

The working group decided to include PD, as defined by International Classification of Diseases 11th revision (ICD-11). Eleven core outcomes and three optional outcomes across four health domains (mental health, behaviour, functioning and recovery) were defined as those relevant for people with PD. Validated measures for the selected outcomes were selected, some covering more than one outcome. Case-mix variables were aligned to other ICHOM mental health standard sets and consisted of demographic factors and those related to the treatment that people received. The group recommended that most outcomes are measured at baseline and annually.

CONCLUSION

The international minimum standard set of outcomes has the potential to improve clinical decision making through systematic measurement and comparability. This will be key in improving the standard of health care for people with PD across the world.

Radical Prostatectomy: Sequelae in the Course of Time

Objective: Radical prostatectomy (RP) is a frequent treatment for men suffering from localized prostate cancer (PCa). Whilst offering a high chance for cure, it does not come without a significant impact on health-related quality of life. Herein we review the common adverse effects RP may have over the course of time. Methods: A collaborative narrative review was performed with the identification of the principal studies on the topic. The search was executed by a relevant term search on PubMed from 2010 to February 2021. Results: Rates of major complications in patients undergoing RP are generally low. The main adverse effects are erectile dysfunction varying from 11 to 87% and urinary incontinence varying from 0 to 87% with a peak in functional decline shortly after surgery, and dependent on definitions. Different less frequent side effects also need to be taken into account. The highest rate of recovery is seen within the first year after RP, but even long-term improvements are possible. Nevertheless, for some men these adverse effects are long lasting and different, less frequent side effects also need to be taken into account. Despite many technical advances over the last two decades no surgical approach can be clearly favored when looking at long-term outcome, as surgical volume and experience as well as individual patient characteristics are still the most influential variables. Conclusions: The frequency of erectile function and urinary continence side effects after RP, and the trajectory of recovery, need to be taken into account when counseling patients about their treatment options for prostate cancer.

Preoperative exercise interventions to optimize continence outcomes following radical prostatectomy

Urinary incontinence is a common and predictable consequence among men with localized prostate cancer who have undergone radical prostatectomy. Despite advances in the surgical technique, urinary continence recovery time remains variable. A range of surgical and patient-related risk factors contributing to urinary incontinence after radical prostatectomy have been described, including age, BMI, membranous urethral length and urethral sphincter insufficiency. Physical activity interventions incorporating aerobic exercise, resistance training and pelvic floor muscle training programmes can positively influence the return to continence in men after radical prostatectomy. Traditional approaches to improving urinary continence after radical prostatectomy have typically focused on interventions delivered during the postoperative period (rehabilitation). However, the limited efficacy of these postoperative approaches has led to a shift from the traditional reactive model of care to more comprehensive interventions incorporating exercise-based programmes that begin in the preoperative period (prehabilitation) and continue after surgery. Comprehensive prehabilitation interventions include appropriately prescribed aerobic exercise, resistance training and specific pelvic floor muscle instruction and exercise training programmes. Transperineal ultrasonography is a non-invasive and validated method for the visualization of the action of the pelvic floor musculature, providing real-time visual biofeedback to the patient during specific pelvic floor muscle instruction and training. Importantly, the waiting time before surgery can be used for the delivery of comprehensive prehabilitation exercise-based interventions to increase patient preparedness in the lead-up to surgery and optimize continence and health-related quality-of-life outcomes following radical prostatectomy.

Organization of outcome-based quality improvement in Dutch heart centres

AIMS

Fourteen Dutch heart centres collected patient-relevant outcomes to support quality improvements in a value-based healthcare initiative that began in 2012. This study aimed to evaluate the current state of outcome-based quality improvement within six of these Dutch heart centres.

METHODS AND RESULTS

Interviews and questionnaires among physicians and healthcare professionals in the heart centres were combined in a mixed-methods approach. The analysis indicates that the predominant focus of the heart centres is on the actual monitoring of outcomes. A systematic approach for the identification of improvement potential and the selection and implementation of improvement initiatives is lacking. The organizational context for outcome-based quality improvement is similar in the six heart centres.

CONCLUSION

Although these heart centres in the Netherlands measure health outcomes for the majority of cardiac diseases, the actual use of these outcomes to improve quality of care remains limited. The main barriers are limitations regarding (i) data infrastructure, (ii) a systematic approach for the identification of improvement potential and the selection and implementation of improvement initiatives, (iii) governance in which roles and responsibilities of physicians regarding outcome improvement are formalized, and (iv) implementation of outcomes within hospital strategy, policy documents, and the planning and control cycle.

Development of the First Patient-centred Set of Outcomes for Muscle-invasive and Metastatic Bladder Cancer: A Multicentre Initiative

BACKGROUND

To improve and compare outcomes in healthcare, it is necessary to standardise outcome measurements. There are no widely accepted standardised outcome measures reflecting quality of care for bladder cancer (BCa) patients.

OBJECTIVE

The aim of this study was to create a standardised set of outcomes for patients with muscle-invasive or metastatic BCa, using the value-based healthcare principles.

DESIGN SETTING AND PARTICIPANTS

A multidisciplinary working group of 25 healthcare professionals and patient representatives was assembled, to develop the set.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

We used an online RAND-modified Delphi process to prioritise, discuss, and reach consensus regarding the outcomes, case-mix variables, and treatment factors.

RESULTS AND LIMITATIONS

Recognising the heterogeneity of patients with BCa, the working group defined the scope as patients with muscle-invasive and metastatic BCa. A total of 24 outcomes, including ten patient-reported outcomes, were included in the standard set of outcomes, covering survival, complication rates, recurrence of disease, readmissions after treatment, and quality of life (QoL). Fourteen case-mix variables were included. The EQ-5D and European Organisation for Research and Treatment of Cancer quality of life (EORTC-QLQ) questionnaires were recommended to measure QoL.

CONCLUSIONS

We developed the first standardised set of patient-centred outcomes for muscle-invasive and metastatic BCa. The sue of this set enables institutions to monitor, compare, and improve the quality of BCa care, on an international level.

PATIENT SUMMARY

Our group of healthcare professionals and patient representatives recommended a standardised set of patient-centred outcomes to be followed during the treatment of patients with muscle-invasive or metastatic bladder cancer, in order to monitor, compare, and improve the quality of care.

Construct Validity of the Questionnaire Quality From the Patients Perspective Adapted for Surgical Prostate Cancer Patients

Patient-reported experience measures (PREMs) are important to capture the patients’ voice. No such measure is routinely used for evaluation after robotic-assisted radical prostatectomy for prostate cancer. The aim of this study was to adapt the short version of the PREM questionnaire quality from the patients’ perspective (QPP), and assess the construct validity of this version. Quality from the patients’ perspective assesses 4 dimensions of quality of care. Involving discussion with user representatives, the QPP short version was adapted by adding 7 context-specific questions based on items from the Expanded Prostate Cancer Index Composite for Clinical Practice. This short version was answered on smartphone or tablet by 265 patients. We used exploratory factor analysis to assess dimensionality. For comparison with previous publications of the QPP, the analysis was repeated after mean imputation of missing values. The factor analysis identified 7 factors among the 30 analyzed items included in the analysis, explaining 64.9% of the variance. After imputation of missing, 2 factors explained 48.6% of the variance. None of these analysis captured the 4 dimensions of the QPP.

A Standard Set of Value-Based Patient-Centered Outcomes for Pancreatic Carcinoma: An International Delphi Survey

BACKGROUND

Global health systems are shifting toward value-based health care to improve patient outcomes in the face of rising health care costs. The challenge is to identify standardized outcome measurements that allow optimal quality-of-care monitoring and comparison to optimize medical practices and patient pathways. A common outcomes definition is required, including medical results (Clinical Reported Outcomes Measurements [CROMs]) and quality-of-life components that matter most to patients (Patient-Reported Outcomes Measurements [PROMs]), which are particularly important for severe pathologies with short life expectancy such as pancreatic cancer. This study aimed to create standardized metrics that could be used for outcomes analysis of pancreatic cancer care.

METHODS

A multidisciplinary working group (WG) was assembled. A systematic review was performed to collect the most used outcomes in clinical studies of pancreatic cancers. The study reviewed 570 studies published in the last 10 years. From these studies, 3370 outcomes, including CROMs, and PROMs, were listed and prioritized. The WG reached a consensus on key outcomes, proposed groupings for CROMs and PROMs, identified existing questionnaires that could be used for PROMs collection, and set the timeline for data collection. To refine and validate the final outcomes set, an international external committee completed a Delphi process (two rounds for both CROMS and PROMs).

RESULTS

After the systematic literature review, the WG selected 102 outcomes (92 CROMs and 10 PROMs) for submission to the international Delphi vote committee. The committee retrained 89 outcomes (78 CROMs and 11 PROMs). For the PROMs, the WG and the international external committee chose a validated questionnaire, the Functional Assessment of Cancer Therapy-Hepatobiliary, which covers all of the 11 selected PROMs.

CONCLUSIONS

A standardized set of outcome measures that need to be validated through international health outcome comparisons and quality-of-care assessments was built. Pilot projects are underway to test and optimize the approach in real-life conditions.

[Does structural and process quality of certified prostate cancer centers result in better medical care?]

BACKGROUND

An improved structural and process quality could be demonstrated 13 years after certification of the first German prostate cancer center. The question of optimization of the functional quality by establishing organ cancer centers arises.

OBJECTIVE

A critical benefit-risk analysis of organ cancer centers was carried out to evaluate an improved quality of results.

MATERIAL AND METHODS

Based on published results from individual centers and the individual annual reports of the German Cancer Society (DKG), the data for evaluating the quality of results were checked. For the issuing of certificates, the focus is on quality indicators for oncological surgery. The functional quality of results is assessed exclusively by a questionnaire-based survey.

RESULTS

An improvement in the quality of functional results after radical prostatectomy has not yet been demonstrated. The functional quality features of urinary continence and erectile function that are essential for the quality of life and patient satisfaction are only insufficiently assessed due to the lack of objective measuring instruments and are not relevant for certification. There is no reliable evidence for improved overall survival, reduction in tumor-specific mortality, and optimization of functional results in certified centers.

CONCLUSION

The relationship between certification and excellence cannot be proven without individual consideration of a surgeon-specific pentafecta analysis. For this reason, certification-relevant surgeon-related quality assurance is recommended.

[Quality criteria in urology : How to obtain comparable results?]

The standardization of procedural flow and medical documentation increasingly allows further possibilities. The best-known example of process standardization is the centralized treatment of complex clinical pictures, while patient-reported outcome measurements (PROMs) enable standardized documentation. Using the example of prostate cancer, existing literature on the topic of quality optimization in medicine is discussed. The following key points are addressed: (1) Increasing use of standardized PROMs for outcome documentation. (2) The transfer of complex clinical pictures to dedicated specialized centers has been shown to increase the quality of patient care as long as standardized PROMs are used. (3) Healthcare policymakers benefit from the use of PROMs and increasingly pursue a "value-based healthcare" approach.

Value-Based Healthcare in Urology: A Collaborative Review

CONTEXT

In response to growing concerns over rising costs and major variation in quality, improving value for patients has been proposed as a fundamentally new strategy for how healthcare should be delivered, measured, and remunerated.

OBJECTIVE

To systematically review the literature regarding the implementation and impact of value-based healthcare in urology.

EVIDENCE ACQUISITION

A systematic review was performed to identify studies that described the implementation of one or more elements of value-based healthcare in urologic settings and in which the associated change in healthcare value had been measured. Twenty-two publications were selected for inclusion.

EVIDENCE SYNTHESIS

Reorganization of urologic care around medical conditions was associated with increased use of guidelines-compliant care for men with prostate cancer, and improved outcomes for patients with lower urinary tract symptoms. Measuring outcomes for every patient was associated with improved prostate cancer outcomes, while the measurement of costs using time-driven activity-based costing was associated with reduced resource utilization in a pediatric multidisciplinary clinic. Centralization of urologic cancer care in the UK, Denmark, and Canada was associated with overall improved outcomes, although systems integration in the USA yielded mixed results among urologic cancer patients. No studies have yet examined bundled payments for episodes of care, expanding the geographic reach for centers of excellence, or building enabling information technology platforms.

CONCLUSIONS

Few studies have critically assessed the actual or simulated implementation of value-based healthcare in urology, but the available literature suggests promising early results. In order to effectively redesign care, there is a need for further research to both evaluate the potential results of proposed value-based healthcare interventions and measure their effects where already implemented.

PATIENT SUMMARY

While few studies have evaluated the implementation of value-based healthcare in urology, the available literature suggests promising early results.

Measuring psychosocial outcomes of men living with prostate cancer: feasibility of regular assessment of patient-reported outcomes

OBJECTIVE

To trial collecting patient-reported outcome measures (PROMs) to assess psychosocial outcomes in men with prostate cancer (PC).

METHODS

A cross-sectional postal survey was sent to three groups of 160 men with PC (6, 12 and 24 months post-initial treatment; n_total  = 480), through the South Australian Prostate Cancer Clinical Outcomes Collaborative (SAPCCOC) registry (2017). Outcomes were as follows: response rate, completeness, general and disease-specific quality of life, distress, insomnia, fear of recurrence, decisional difficulties and unmet need.

RESULTS

A response rate of 57-61% (n = 284) was achieved across groups. Data completeness was over 90% for 88% of survey items, with lower response (76-78%) for EPIC-26 urinary and sexual functioning subscales, sexual aid use (78%) and physical activity (68%). In general, higher socio-economic indicators were associated with higher completion of these measures (absolute difference 12-26%, p < 0.05). Lower unmet need on the sexuality domain (SCNS-SF34) was associated with lower completion of the EPIC-26 sexual functioning subscale [M (SD) = 12.4 (21.6); M (SD) = 26.3 (27.3), p < .001]. Worse leaking urine was associated with lower completion of urinary pad/diaper use question (EPIC-26) [M (SD) = 65.9 (26.5), M (SD) = 77.3 (23.9), p < .01].

CONCLUSION

Assessment of psychosocial PROMs through a PC registry is feasible and offers insight beyond global quality of life assessment, to facilitate targeting and improvements in services and treatments.

Prostatectomy with or without post-operative radiotherapy: long-term adverse effects and quality of life

BACKGROUND

Few longitudinal studies have compared patient-reported long-term adverse effects after radical prostatectomy (RP) alone and RP followed by radiotherapy (RAD), also analyzing the effect of the development of post-treatment dysfunctions/problems (Symptom Burden) on Health-Related Quality of Life (HRQoL).

MATERIAL AND METHODS

After median seven years since RP and six years since post-RP RAD, development of EPIC-26 Domain Summary Scores (DSS Changes) and HRQoL scores (SF-12) since the pre-RP situation were evaluated in respectively 317 prostatectomized men without and in 63 patients with additional post-RP RAD. Post-treatment inter-group differences of the prevalent Symptom Burden and of the DSS Changes were calculated. Multivariable logistic regressions evaluated the associations between DSS Changes and post-treatment impaired HRQoL.

RESULTS

Compared to RP alone, post-RP RAD increased the post-treatment Symptom Burden, with least inter-group differences within the urinary irritative/obstructive and bowel domain. No significant inter-group difference emerged for the proportions of men with impaired HRQoL. The odds of impaired HRQoL increased significantly with rising DSS Changes (worsening) within the vitality/hormonal domain. Worsening within urinary incontinence and bowel domains significantly increased the odds of impaired physical QoL. High HRQoL scores before RP reduced the odds of post-treatment impaired HRQoL. Living without a partner and use of androgen deprivation therapy increased this odds.

CONSLUSIONS

Post-RP radiotherapy increases post-treatment Symptom Burden with negative, though limited impact on the patient's HRQoL. Counceling before post-RP radiotherapy should cover this possible development, taking into account the patient's social situation.

Influence of deprivation and rurality on patient-reported outcomes of men living with and beyond prostate cancer diagnosis in the UK: A population-based study

BACKGROUND

In the UK, inequalities exist in prostate cancer incidence, survival and treatment by area deprivation and rurality. This work aimed to identify variation in patient-reported outcomes of men with prostate cancer by area type.

METHODS

A population-based survey of men 18-42 months after prostate cancer diagnosis (N = 35608) measured self-assessed health (SAH) using the EQ-5D and five functional domains using the Expanded Prostate Cancer Index Composite (EPIC-26).

RESULTS

Mean SAH was higher for men in least deprived areas compared to most deprived (difference 6.3 (95 %CI 5.6-7.2)). SAH scores were lower for men in most urban areas compared to most rural (difference 2.4 (95 %CI 1.8-3.0)). Equivalent estimates in the general population reported a 13 point difference by deprivation and a 4 point difference by rurality. For each EPIC-26 domain, functional outcomes were better for men in the least deprived areas, with clinically meaningful differences observed for urinary incontinence and hormonal function. There were no clinically meaningful differences in EPIC-26 outcomes by rurality with less than a three point difference in scores for each domain between urban and rural areas.

CONCLUSION

In men 18-42 months post diagnosis of prostate cancer in the UK, impacts of area deprivation and rurality on self-assessed health related quality of life were not greater than would be expected in the general population. However, clinically meaningful differences were identified for some prostate functional outcomes (urinary and hormonal function) by deprivation. No impact by rurality of residence was identified.

Treatment patterns and clinical outcomes of chemotherapy treatment in patients with muscle-invasive or metastatic bladder cancer in the Netherlands

This retrospective study was performed to evaluate real-world oncological outcomes of patients treated with chemo-based therapy for muscle-invasive or metastatic bladder cancer (MIBC/mBC) and compare results to data from RCTs and other cohorts. Among 1578 patients diagnosed, 470 (30%) had MIBC/mBC. Median overall survival (mOS) for RC alone (47 months), first-line (13 months) and second-line (7 months) chemotherapy, and chemotherapy for recurrent disease (8 months) were similar to literature. Treatment with neoadjuvant and induction chemotherapy (NAIC) was only utilized in 9% of patients, and often in patients with poor disease status, resulting in a lower mOS compared to literature (35 and 20 months, respectively). Patients treated with chemotherapy had many adversities to treatment, with only 50%, 13%, 18% and 7% of patients in NAIC, first-line, salvage after RC, and second-line setting completing the full pre-planned chemotherapy treatment. Real-world data shows NAIC before RC is underutilized. Adversities during chemotherapy treatment are frequent, with many patients requiring dose reduction or early treatment termination, resulting in poor treatment response. Although treatment efficacy between RCTs and real-world patients is quite similar, there are large differences in baseline characteristics and treatment patterns. Possibly, results from retrospective studies on real-world data can deliver missing evidence on efficacy of chemotherapy treatment on older and ‘unfit’ patients.

Core outcome sets in cancer and their approaches to identifying and selecting patient-reported outcome measures: a systematic review

OBJECTIVES

Issues arising from a lack of outcome standardisation in health research may be addressed by the use of core outcome sets (COS), which represent agreed-upon recommendations regarding what outcomes should be measured as a minimum in studies of a health condition. This review investigated the scope, outcomes, and development methods of consensus-based COS for cancer, and their approaches and criteria for selecting instruments to assess core patient-reported outcomes (PROs).

METHODS

Studies that used a consensus-driven approach to develop a COS containing PROs, for use in research with cancer populations, were sought via MEDLINE, CINAHL, Embase, Cochrane Library, and grey literature.

RESULTS

Seventeen studies met the inclusion criteria. Most COS (82%) were specific to a cancer type (prostate, esophageal, head and neck, pancreatic, breast, ovarian, lung, or colorectal) and not specific to an intervention or treatment (76%). Conducting a systematic review was the most common approach to identifying outcomes (88%) and administering a Delphi survey was the most common approach to prioritising outcomes (71%). The included COS contained 90 PROs, of which the most common were physical function, sexual (dys) function, pain, fatigue, and emotional function. Most studies (59%) did not address how to assess the core PROs included in a set, while 7 studies (41%) recommended specific instruments. Their approaches to instrument appraisal and selection varied.

CONCLUSION

Efforts to standardise outcome assessment via the development of COS may be undermined by a lack of recommendations on how to measure core PROs. To optimise COS usefulness and adoption, valid and reliable instruments for the assessment of core PROs should be recommended with the aid of resources designed to facilitate this process.

Validation of "patient-reported outcomes via online questionnaire" as a urinary continence assessment and quality improvement tool following radical prostatectomy

BACKGROUND

Securing reliable data on functional outcomes following radical prostatectomy (RP) is paramount to patient follow-up and management.

OBJECTIVE

To validate an email-based patient-reported outcomes tracking system in assessing pad-free continence rates and time-to continence recovery following RP.

PATIENTS AND METHODS

483 men undergoing RP by a single surgeon from November 2013 to March 2019 were prospectively assigned to 1 of 3 tracking systems: 1) a preaddressed paper packet containing a pad-free card and daily urinary pad log, (N = 249); 2) an automated email questionnaire, (N = 234) or 3) both (N = 51). Patients tracked electronically received electronic Research Electronic Data Capture surveys 30 days after catheter removal, with up to 3 reminders sent automatically if no response was received within 2 days. Response rates and continence rates were compared in group 1 vs. group 2 via student t-tests; time-to pad-free status was assessed for concordance among men in group 3 via linear regression.

RESULTS

Thirty-day response rates in group 1 (paper) vs. group 2 (electronic) were 80.7% (201/249) and 94.0% (220/234), (P < 0.0001); pad-free rates were 64.2% (129/201) and 64.1% (141/220), (P = 0.9847), respectively. Similarly, 1-year response rates in group 1 and 2 were 87.6% (218/249) vs. 94.0% (220/234), (P = 0.0146); pad-free rates were 91.7% (200/218) vs. 96.4% (212/220), (P = 0.0411), respectively. In group 3, time to pad-free continence recovery assessed via Patient Reported Outcomes via Online Questionnaire (PROVOQ) was highly concordant in 89.6% (43/48) of patients ± 5 days (Figure 1, R² = 0.9893). No significant bias was found for subsequent reporting in either group.

CONCLUSION

The use of automated email survey questionnaires via PROVOQ for the assessment of patient-reported post-RP continence recovery facilitates increased response rates, timeliness of response, and accuracy. PROVOQ significantly reduce the labor of tracking continence outcomes, improve quality improvement efforts, and enables surgeons to more clearly differentiates risk of long-term incontinence.

Active monitoring, radical prostatectomy and radical radiotherapy in PSA-detected clinically localised prostate cancer: the ProtecT three-arm RCT

BACKGROUND

Prostate cancer is the most common cancer among men in the UK. Prostate-specific antigen testing followed by biopsy leads to overdetection, overtreatment as well as undertreatment of the disease. Evidence of treatment effectiveness has lacked because of the paucity of randomised controlled trials comparing conventional treatments.

OBJECTIVES

To evaluate the effectiveness of conventional treatments for localised prostate cancer (active monitoring, radical prostatectomy and radical radiotherapy) in men aged 50-69 years.

DESIGN

A prospective, multicentre prostate-specific antigen testing programme followed by a randomised trial of treatment, with a comprehensive cohort follow-up.

SETTING

Prostate-specific antigen testing in primary care and treatment in nine urology departments in the UK.

PARTICIPANTS

Between 2001 and 2009, 228,966 men aged 50-69 years received an invitation to attend an appointment for information about the Prostate testing for cancer and Treatment (ProtecT) study and a prostate-specific antigen test; 82,429 men were tested, 2664 were diagnosed with localised prostate cancer, 1643 agreed to randomisation to active monitoring (n = 545), radical prostatectomy (n = 553) or radical radiotherapy (n = 545) and 997 chose a treatment.

INTERVENTIONS

The interventions were active monitoring, radical prostatectomy and radical radiotherapy.

TRIAL PRIMARY OUTCOME MEASURE

Definite or probable disease-specific mortality at the 10-year median follow-up in randomised participants.

SECONDARY OUTCOME MEASURES

Overall mortality, metastases, disease progression, treatment complications, resource utilisation and patient-reported outcomes.

RESULTS

There were no statistically significant differences between the groups for 17 prostate cancer-specific (p = 0.48) and 169 all-cause (p = 0.87) deaths. Eight men died of prostate cancer in the active monitoring group (1.5 per 1000 person-years, 95% confidence interval 0.7 to 3.0); five died of prostate cancer in the radical prostatectomy group (0.9 per 1000 person-years, 95% confidence interval 0.4 to 2.2 per 1000 person years) and four died of prostate cancer in the radical radiotherapy group (0.7 per 1000 person-years, 95% confidence interval 0.3 to 2.0 per 1000 person years). More men developed metastases in the active monitoring group than in the radical prostatectomy and radical radiotherapy groups: active monitoring, n = 33 (6.3 per 1000 person-years, 95% confidence interval 4.5 to 8.8); radical prostatectomy, n = 13 (2.4 per 1000 person-years, 95% confidence interval 1.4 to 4.2 per 1000 person years); and radical radiotherapy, n = 16 (3.0 per 1000 person-years, 95% confidence interval 1.9 to 4.9 per 1000 person-years; p = 0.004). There were higher rates of disease progression in the active monitoring group than in the radical prostatectomy and radical radiotherapy groups: active monitoring (n = 112; 22.9 per 1000 person-years, 95% confidence interval 19.0 to 27.5 per 1000 person years); radical prostatectomy (n = 46; 8.9 per 1000 person-years, 95% confidence interval 6.7 to 11.9 per 1000 person-years); and radical radiotherapy (n = 46; 9.0 per 1000 person-years, 95% confidence interval 6.7 to 12.0 per 1000 person years; p < 0.001). Radical prostatectomy had the greatest impact on sexual function/urinary continence and remained worse than radical radiotherapy and active monitoring. Radical radiotherapy's impact on sexual function was greatest at 6 months, but recovered somewhat in the majority of participants. Sexual and urinary function gradually declined in the active monitoring group. Bowel function was worse with radical radiotherapy at 6 months, but it recovered with the exception of bloody stools. Urinary voiding and nocturia worsened in the radical radiotherapy group at 6 months but recovered. Condition-specific quality-of-life effects mirrored functional changes. No differences in anxiety/depression or generic or cancer-related quality of life were found. At the National Institute for Health and Care Excellence threshold of £20,000 per quality-adjusted life-year, the probabilities that each arm was the most cost-effective option were 58% (radical radiotherapy), 32% (active monitoring) and 10% (radical prostatectomy).

LIMITATIONS

A single prostate-specific antigen test and transrectal ultrasound biopsies were used. There were very few non-white men in the trial. The majority of men had low- and intermediate-risk disease. Longer follow-up is needed.

CONCLUSIONS

At a median follow-up point of 10 years, prostate cancer-specific mortality was low, irrespective of the assigned treatment. Radical prostatectomy and radical radiotherapy reduced disease progression and metastases, but with side effects. Further work is needed to follow up participants at a median of 15 years.

A multicenter paper-based and web-based system for collecting patient-reported outcome measures in patients undergoing local treatment for prostate cancer: first experiences

PURPOSE

To give an overview of the multicenter Prostate Cancer Outcomes (PCO) study, involving paper-based and web-based collection of patient-reported outcome measures (PROM) in patients undergoing local treatment for prostate cancer in certified centers in Germany. The PCO study is part of the larger Movember-funded TrueNTH Global Registry. The article reports on the study's design and provides a brief progress report after the first 2 years of data collection.

METHODS

Prostate cancer centers (PCCs) certified according to German Cancer Society requirements were invited to participate in collecting patient-reported information on symptoms and function before and at least once (at 12 months) after treatment. The data were matched with disease and treatment information. This report describes progress in patient inclusion, response rate, and variations between centers relative to online/paper use, and also data quality, including recruitment variations relative to treatment in the first participating PCCs.

RESULTS

PCC participation increased over time; 44 centers had transferred data for 3094 patients at the time of this report. Patient recruitment varied widely across centers. Recruitment was highest among patients undergoing radical prostatectomy. The completeness of the data was good, except for comorbidity information.

CONCLUSIONS

The PCO study benefits from a quality improvement system first established over 10 years ago, requiring collection and harmonization of a predefined clinical dataset across centers. Nevertheless, establishing a PROM routine requires substantial effort on the part of providers and constant monitoring in order to achieve high-quality data. The findings reported here may be useful for guiding implementation in similar initiatives.

Patient-Reported Quality of Life and Convalescence After Minimally Invasive Kidney Cancer Surgery

OBJECTIVE

To better characterize recovery after minimally invasive kidney surgery, we present a study describing patient-reported health-related quality of life (HRQOL) following minimally invasive radical nephrectomy (RN) and partial nephrectomy (PN).

METHODS

Patients who underwent minimally invasive PN or RN for renal cancer were invited to enroll in a prospective, patient-reported HRQOL study using the Convalescence and Recovery Evaluation (CARE) instrument and Short Form-12. Patients completed questionnaires at baseline, 2, 4, 8, and 12 weeks after surgery. Mixed repeated measures model were used to assess time effect on HRQOL scores and predictors of scores within each surgery groups.

RESULTS

One hundred seventy-seven patients were included in the study: 50 had RN and 127 had PN. At 2 weeks, both groups had significant decreases in Overall CARE, as well as the Pain, Gastrointestinal, and Activity domain scores which remained slightly below baseline at 4 weeks. At 4 weeks only 50% of patients in both the RN and PN cohorts returned to baseline overall CARE score. By 12 weeks 82% returned to baseline overall CARE score in the RN group while 76% of patients did so in the PN group.

CONCLUSION

Convalescence after minimally invasive renal surgery can often extend beyond 4 weeks post-treatment in PN and RN subjects. This information may be used to provide more accurate preoperative counseling in an attempt to improve overall patient satisfaction.

The Prostate Cancer Outcomes (PCO) study in prostate cancer centres certified by the German Cancer Society

Since 2016, certified prostate cancer centres have been able to participate in the Prostate Cancer Outcomes (PCO) study. The aim of this study is to compare outcomes across centres after local treatment for prostate cancer. The study originated from a support group initiative and is jointly carried out by the German Cancer Society (Deutsche Krebsgesellschaft), the certification institute OnkoZert, patient support groups and the participating centres. So far, centres have been more successful at recruiting patients undergoing surgery than those receiving radiotherapy as the definitive treatment. This means that conclusions for the latter group of patients are almost impossible. It is important to us that all types of treatment are equally well represented in the study; thus, we encourage radiation therapists to participate in the PCO study.

Validation of a Questionnaire-Suitable Comorbidity Index in Patients Undergoing Radical Cystectomy

OBJECTIVE

To investigate the capability of a modified self-administrable comorbidity index recommended in the standard sets for neoplastic diseases published by the International Consortium for Health Outcomes Measurement (ICHOM) to predict 90-day and long-term mortality after radical cystectomy.

METHODS

A single-center series of 1,337 consecutive patients who underwent radical cystectomy for muscle-invasive or high-risk non-muscle-invasive urothelial or undifferentiated bladder cancer were stratified by the modified self-administrable comorbidity index and Charlson score, respectively. Multivariate logit models (for 90-day mortality) and proportional-hazards models (for overall and non-bladder cancer mortality) were used for statistical workup.

RESULTS

Considering 90-day mortality, both comorbidity indexes contributed independent information when analyzed together with age (p < 0.0001). The Charlson score performed slightly better (area under the curve [AUC] 0.74 vs. 0.72 for the ICHOM-recommended comorbidity index). Considering 5-year overall mortality in 727 patients with complete observation, the performance of both measures was similar (AUC 0.63 vs. 0.62, including age AUC 0.66 for both indexes). With 6-sided stratifications, the modified self-administrable comorbidity index separated the risk groups slightly better (p values for directly neighboring curves: 0.0068-0.1043 vs. 0.0001-0.8100).

CONCLUSION

The ICHOM-recommended modified self-administrable comorbidity index is capable of predicting 90-day mortality and long-term non-bladder cancer mortality after radical cystectomy similarly to the commonly used Charlson score.

Single institution followed by national implementation of systematic surgical quality control and feedback for radical prostatectomy: a 20-year journey

PURPOSE

The demand for objective and outcome-based facts about surgical results after radical prostatectomy (RP) is increasing. Systematic feedback is also essential for each surgeon to improve his/her performance.

METHODS

RP outcome data (e.g., pT-stage and margin status) have been registered at Sahlgrenska University Hospital (SUH) since 1988 and patient-related outcome measures (PROM) have been registered since 2001. The National Prostate Cancer Registry (NPCR) has covered all Regions in Sweden since 1998 and includes PROM-data from 2008. Initially PROM was on-paper questionnaires but due since 2018 all PROMs are collected electronically. In 2014 an on-line "dashboard" panel was introduced, showing the results for ten quality-control variables in real-time. Since 2017 all RP data on hospital, regional, and national levels are publicly accessible on-line on "www.npcr.se/RATTEN".

RESULTS

The early PROM-data from SUH have been used for internal quality control. As national clinical and PROM-data from the NPCR have been made accessible on-line and in real-time we have incorporated this into our pre-existing protocol. Our data are now internally available as real-time NPCR reports on the individual surgeons' results, as well as ePROM data. We can compare the results of each surgeon internally and to other departments' aggregated data. The public can access data and compare hospital level data on "RATTEN".

CONCLUSIONS

The process of quality control of RP locally at SUH, and nationally through the NPCR, has been long but fruitful. The online design, with direct real-time feedback to the institutions that report the data, is essential.

Introducing PIONEER: a project to harness big data in prostate cancer research

Prostate Cancer Diagnosis and Treatment Enhancement Through the Power of Big Data in Europe (PIONEER) is a European network of excellence for big data in prostate cancer, consisting of 32 private and public stakeholders from 9 countries across Europe. Launched by the Innovative Medicines Initiative 2 and part of the Big Data for Better Outcomes Programme (BD4BO), the overarching goal of PIONEER is to provide high-quality evidence on prostate cancer management by unlocking the potential of big data. The project has identified critical evidence gaps in prostate cancer care, via a detailed prioritization exercise including all key stakeholders. By standardizing and integrating existing high-quality and multidisciplinary data sources from patients with prostate cancer across different stages of the disease, the resulting big data will be assembled into a single innovative data platform for research. Based on a unique set of methodologies, PIONEER aims to advance the field of prostate cancer care with a particular focus on improving prostate-cancer-related outcomes, health system efficiency by streamlining patient management, and the quality of health and social care delivered to all men with prostate cancer and their families worldwide.

International Consortium for Health Outcome Measurement Set of Outcomes That Matter to People Living With Inflammatory Arthritis: Consensus From an International Working Group

Objective

The implementation of value‐based health care in inflammatory arthritis requires a standardized set of modifiable outcomes and risk‐adjustment variables that is feasible to implement worldwide.

Methods

The International Consortium for Health Outcomes Measurement (ICHOM) assembled a multidisciplinary working group that consisted of 24 experts from 6 continents, including 6 patient representatives, to develop a standard set of outcomes for inflammatory arthritis. The process followed a structured approach, using a modified Delphi process to reach consensus on the following decision areas: conditions covered by the set, outcome domains, outcome measures, and risk‐adjustment variables. Consensus in areas 2 to 4 were supported by systematic literature reviews and consultation of experts.

Results

The ICHOM Inflammatory Arthritis Standard Set covers patients with rheumatoid arthritis (RA), axial spondyloarthritis, psoriatic arthritis, and juvenile idiopathic arthritis (JIA). We recommend that outcomes regarding pain, fatigue, activity limitations, overall physical and mental health impact, work/school/housework ability and productivity, disease activity, and serious adverse events be collected at least annually. Validated measures for patient‐reported outcomes were endorsed and linked to common reporting metrics. Age, sex at birth, education level, smoking status, comorbidities, time since diagnosis, and rheumatoid factor and anti‐citrullinated protein antibody lab testing for RA and JIA should be collected as risk‐adjustment variables.

Conclusion

We present the ICHOM inflammatory arthritis Standard Set of outcomes, which enables health care providers to implement the value‐based health care framework and compare outcomes that are important to patients with inflammatory arthritis.

Use of psycho-oncological services by prostate cancer patients: A multilevel analysis

Background

Cancer patients often suffer from psychological distress. Psycho‐oncological services (POS) have been established in some health care systems in order to address such issues. This study aims to identify patient and center characteristics that elucidate the use of POS by patients in prostate cancer centers (PCCs).

Methods

Center‐reported certification and patient survey data from 3094 patients in 44 certified PCCs in Germany were gathered in the observational study (Prostate Cancer Outcomes). A multilevel analysis was conducted.

Results

Model 1 showed that utilization of POS in PCCs is associated with patients’ age (OR = 0.98; 95%‐CI = 0.96‐0.99; P < .001), number of comorbidities (1‐2 vs 0, OR = 1.27; 95%‐CI = 1.00‐1.60; P=.048), disease staging (localized high‐risk vs localized intermediate risk, OR = 1.41; 95%‐CI = 1.14‐1.74; P < .001), receiving androgen deprivation therapy before study inclusion (OR = 0.19; 95%‐CI = 0.10‐0.34; P < .001), and hospital teaching status (university vs academic, OR = 0.09; 95%‐CI = 0.02‐0.55; P = .009). Model 2 additionally includes information on treatment after study inclusion and shows that after inclusion, patients who receive primary radiotherapy (OR = 0.05; 95%‐CI = 0.03‐0.10; P < .001) or undergo active surveillance/watchful waiting (OR = 0.06; 95%‐CI = 0.02‐0.15; P < .001) are less likely to utilize POS than patients who undergo radical prostatectomy. Disease staging (localized high‐risk vs localized intermediate risk, OR = 1.31; 95%‐CI = 1.05‐1.62; P = .02) and teaching status (university vs academic, OR = 0.08; 95%‐CI = 0.01‐0.65; P = .02) are also significant predictors for POS use. The second model did not identify any other significant patient characteristics.

Conclusions

Future research should explore the role of institutional teaching status and whether associations with therapy after study inclusion are due to treatment effects – for example, less need following radiotherapy – or because access to POS is more difficult for those receiving radiotherapy.

A scoping review of core outcome sets and their 'mapping' onto real-world data using prostate cancer as a case study

BACKGROUND

A Core Outcomes Set (COS) is an agreed minimum set of outcomes that should be reported in all clinical studies related to a specific condition. Using prostate cancer as a case study, we identified, summarized, and critically appraised published COS development studies and assessed the degree of overlap between them and selected real-world data (RWD) sources.

METHODS

We conducted a scoping review of the Core Outcome Measures in Effectiveness Trials (COMET) Initiative database to identify all COS studies developed for prostate cancer. Several characteristics (i.e., study type, methods for consensus, type of participants, outcomes included in COS and corresponding measurement instruments, timing, and sources) were extracted from the studies; outcomes were classified according to a predefined 38-item taxonomy. The study methodology was assessed based on the recent COS-STAndards for Development (COS-STAD) recommendations. A 'mapping' exercise was conducted between the COS identified and RWD routinely collected in selected European countries.

RESULTS

Eleven COS development studies published between 1995 and 2017 were retrieved, of which 8 were classified as 'COS for clinical trials and clinical research', 2 as 'COS for practice' and 1 as 'COS patient reported outcomes'. Recommended outcomes were mainly categorized into 'mortality and survival' (17%), 'outcomes related to neoplasm' (18%), and 'renal and urinary outcomes' (13%) with no relevant differences among COS study types. The studies generally fulfilled the criteria for the COS-STAD 'scope specification' domain but not the 'stakeholders involved' and 'consensus process' domains. About 72% overlap existed between COS and linked administrative data sources, with important gaps. Linking with patient registries improved coverage (85%), but was sometimes limited to smaller follow-up patient groups.

CONCLUSIONS

This scoping review identified few COS development studies in prostate cancer, some quite dated and with a growing level of methodological quality over time. This study revealed promising overlap between COS and RWD sources, though with important limitations; linking established, national patient registries to administrative data provide the best means to additionally capture patient-reported and some clinical outcomes over time. Thus, increasing the combination of different data sources and the interoperability of systems to follow larger patient groups in RWD is required.

An International Collaborative Standardizing Patient-Centered Outcome Measures in Pediatric Facial Palsy

Importance

Standardization of outcome measurement using a patient-centered approach in pediatric facial palsy may help aid the advancement of clinical care in this population.

Objective

To develop a standardized outcome measurement set for pediatric patients with facial palsy through an international multidisciplinary group of health care professionals, researchers, and patients and patient representatives.

Design, Setting, and Participants

A working group of health care experts and patient representatives (n = 21), along with external reviewers, participated in the study. Seven teleconferences were conducted over a 9-month period between December 3, 2016, and September 23, 2017, under the guidance of the International Consortium for Health Outcomes Measurement, each followed with a 2-round Delphi process to develop consensus. This process defined the scope, outcome domains, measurement tools, time points for measurements, and case-mix variables deemed essential to a standardized outcome measurement set. Each teleconference was informed by a comprehensive review of literature and through communication with patient advisory groups. Literature review of PubMed was conducted for research published between January 1, 1981, and November 30, 2016.

Main Outcomes and Measures

The study aim was to develop the outcomes and measures relevant to children with facial palsy as opposed to studying the effect of a particular intervention.

Results

The 21 members of the working group included pediatric facial palsy experts from 9 countries. The literature review identified 1628 papers, of which 395 (24.3%) were screened and 83 (5.1%) were included for qualitative evaluation. A standard set of outcome measurements was designed by the working group to allow the recording of outcomes after all forms of surgical and nonsurgical facial palsy treatments among pediatric patients of all ages. Unilateral or bilateral, congenital or acquired, permanent or temporary, and single-territory or multiterritory facial palsy can be evaluated using this standard set. Functional, appearance, psychosocial, and administrative outcomes were selected for inclusion. Clinimetric and psychometric outcome measurement tools (clinician-, patient-, and patient proxy-reported) and time points for measuring patient outcomes were established. Eighty-six independent reviews of the standard set were completed, and 34 (85%) of the 40 patients and patient representatives and 44 (96%) of the 46 health care professionals who participated in the reviews agreed that the standard set would capture the outcomes that matter most to children with facial palsy.

Conclusions and Relevance

This international collaborative study produced a free standardized set of outcome measures for evaluating the quality of care provided to pediatric patients with facial palsy, allowing benchmarking of clinicians, comparison of treatment pathways, and introduction of value-based reimbursement strategies in the field of pediatric facial palsy.

Determinants of self-reported functional status (EPIC-26) in prostate cancer patients prior to treatment

PURPOSE

The self-reported functional status (sr-FS) of prostate cancer (PCa) patients varies substantially between patients and health-care providers before treatment. Information about this issue is important for evaluating comparisons between health-care providers and to assist in treatment decision-making. There have been few reports on correlates of pretherapeutic sr-FS. The objective of the article, therefore, is to describe clinical and sociodemographic correlates of pretherapeutic sr-FS, based on a subset of the TrueNTH Global Registry, a prospective cohort study.

METHODS

A total of 3094 PCa patients receiving local treatment in 44 PCa centers in Germany were recruited between July 2016 and April 2018. Multilevel regression models were applied to predict five pretherapeutic sr-FS (EPIC-26) scores based on clinical characteristics (standard set suggested by the International Consortium for Health Outcomes Measurement), sociodemographic characteristics, and center characteristics.

RESULTS

Impaired pretherapeutic sr-FS tended to be associated with lower educational level and poorer disease characteristics-except for "urinary incontinence" which was only associated with age. Notably, age was a risk factor ("urinary incontinence," "urinary irritative/obstructive," "sexual") as well as a protective factor ("hormonal") for pretherapeutic sr-FS. Pretherapeutic sr-FS varies little across centers.

CONCLUSIONS

Pretherapeutic sr-FS varies by clinical patient characteristics and age as well as by socioeconomic status. The findings point out the benefit of collecting and considering socioeconomic information in addition to clinical and demographic patient characteristics for treatment decision-making and fair comparisons between health-care providers.

Integration of Patient Reported Outcomes in Drug Development in Genitourinary Cancers

PURPOSE OF REVIEW

Patient reported outcomes (PROs) are increasingly utilized in cancer drug development, and are of particular importance in genitourinary cancers due to symptom burden, multiple treatment options with similar efficacy, and often prolonged duration of disease. Here we review current data and perspectives related to use of PROs in drug development for genitourinary cancers, including insights on the regulatory process for drug approval.

RECENT FINDINGS

The FDA is committed to incorporating PRO data into the regulatory process for development and approval of new cancer drugs, but challenges exist due to lack of standardization of PRO instrument choice and analytic approach, missing data, and difficulty isolating treatment effect from disease-related effects. We review guidance for standardization of PRO methodology that is nonetheless tailored to disease state and anticipated effects of treatment. PRO and efficacy data should be simultaneously analyzed and reported for best clinical practice. Multiple disease-specific PRO instruments exist for genitourinary cancers. While clinicians, researchers, and regulatory bodies alike recognize the importance of PROs in cancer drug development, challenges remain regarding implementation of best practices.

Incorporating Patient-Reported Outcome Measures into Breast Surgical Oncology: Advancing Toward Value-Based Care

Value in health care is defined as the health outcome achieved per unit of cost. For health care systems, improving value means achieving better outcomes at lower costs. Improving outcomes, including patient-reported outcomes (PROs), as well as more established metrics such as mortality and complication rates, ensures high-quality care. This is particularly true in breast cancer surgery, where survival and recurrence rates are comparable across different surgical approaches. Outcomes reflecting survivorship quality may therefore better inform decision making regarding surgical approaches. PROs can be assessed using validated instruments known as patient-reported outcome measures (PROMs). They are obtained directly from patients reflecting their health-related quality of life (HRQOL). Ongoing initiatives strive to define PROMs that accurately reflect HRQOL and demonstrate value, with the goal of establishing benchmarks for quality of care. Clinicians caring for patients with breast cancer are well positioned to be involved in defining meaningful measures of value-based breast cancer care. This article reviews value-based breast cancer care in the context of locoregional therapy, with attention paid to the work done by the International Consortium of Health Outcome Measures in which a "standard set" of value-based patient-centered outcomes for breast cancer for international use is defined. In addition, an overview is provided of relevant PROMs and previously reported scores. Recommendations and future challenges for implementation of routine collection of PROs are also discussed. IMPLICATIONS FOR PRACTICE: Opportunity exists to act as early adopters of the routine collection of longitudinal patient-reported outcome data for breast cancer, allowing transition of current care to value-based cancer care.

Patient-reported outcome measures after treatment for prostate cancer: Results from the Danish Prostate Cancer Registry (DAPROCAdata)

PURPOSE

This study compares the side effects of active surveillance, prostatectomy, radiation with or without adjuvant endocrine therapy, watchful waiting, and palliative therapy on patient-reported outcomes in a nationwide, population-based cohort of Danish men with prostate cancer.

METHODS

A total of 15,465 participants completed questionnaires over a 5 year period (2011-2016). Condition-specific quality of life, focusing on urinary function, bowel incontinence, sexual function, and hormonal symptoms were investigated using the validated EPIC-26 questionnaire at diagnosis, 1 year- and 3- year follow-up. Patients were identified from the Danish Prostate Cancer Registry with data-linked to several national healthcare registries. Longitudinal analysis with linear mixed effects models were fitted to compare changes over time on quality of life symptom scores for five treatment modalities, adjusting for age, clinical TNM stage, PSA value, Gleason score, Charlson Comorbidity score, education, disposable income, and urbanization measured at time of prostate cancer diagnosis.

RESULTS

There was a more than10-point decrease in mean scores across all symptom domains at 1-year follow-up. Thereafter mean scores for all symptom domains improved marginally and remained relatively unchanged at 3-year follow-up. Prostatectomy had the greatest negative effect on sexual function and urinary incontinence. Overall quality of life was most adversely affected by sexual function, regardless of treatment modality.

CONCLUSION

Clinical interventions for improving symptoms should focus particularly on the first year after prostate cancer diagnosis. Greater emphasis on improving sexual function should be practiced in clinical and rehabilitative care, since this area has the single greatest impact on symptom-specific QoL after primary treatment for prostate cancer.

Evaluating the measurement properties of the 26-item Expanded Prostate Cancer Index Composite (EPIC-26) with a multicenter cohort

INTRODUCTION

We aimed to evaluate the psychometric properties of the 26-item Expanded Prostate Cancer Index Composite (EPIC-26) for measuring the quality of life in patients treated for localized prostate cancer. The EPIC-26 is a patient-reported outcome instrument recommended for use with patients treated for localized prostate cancer.

METHODS

This study is based on data collected prospectively between September 2014 and February 2017 in Alberta, Canada. Men were treated with either radical prostatectomy or radiation therapy and administered the EPIC-26. Responses to the EPIC-26 were the primary outcome. Construct validity was measured using confirmatory factor analysis. Reliability was measured using Chronbach's alpha and item-total correlation. Ceiling and floor effects were also investigated.

RESULTS

EPIC-26 response data from 205 participants (prostatectomy =138; radiation=60; both=7) were used in this analysis. The EPIC-26 was administered an average of 33.8 weeks after treatment. The confirmatory factor analysis model did not meet the threshold for adequate fit. Several items had near-zero factor loadings and were non-significant. Four out of the EPIC-26's five domains met the acceptable reliability threshold based on Cronbach's alpha. Ceiling effects were observed in four out of five domains.

CONCLUSIONS

The EPIC-26 demonstrated poor construct validity, adequate reliability, and large ceiling effects. Several issues were observed, suggesting that the instrument's five domains were not well-defined by their respective items. The original EPIC's conceptual framework should be reviewed and the shortened instrument revised to improve its performance for measuring post-treatment quality of life.

Collaborative governance in the Quebec Cancer Network: a realist evaluation of emerging mechanisms of institutionalization, multi-level governance, and value creation using a longitudinal multiple case study design

BACKGROUND

People living with and beyond cancer (PLC) receive various forms of specialty care at different locations and many interventions concurrently or over time. They are affected by the operation of professional and organizational silos. This results in undue delays in access, unmet needs, sub-optimal care experiences and clinical outcomes, and human and financial costs for PLCs and healthcare systems. National cancer control programs advocate organizing in a network to coordinate actions, solve fragmentation problems, and thus improve clinical outcomes and care experiences for every dollar invested. The variable outcomes of such networks and factors explaining them have been documented. Governance is the "missing link" for understanding outcomes. Governance refers to the coordination of collective action by a body in a position of authority in pursuit of a common goal. The Quebec Cancer Network (QCN) offers the opportunity to study in a natural environment how, why, by whom, for whom, and under what conditions collaborative governance contributes to practices that produce value-added outcomes for PLCs, healthcare providers, and the healthcare system.

METHODS/DESIGN

The study design consists of a longitudinal case study, with multiple nested cases (4 local networks nested in the QCN), mobilizing qualitative and quantitative data and mixed data from various sources and collected using different methods, using the realist evaluation approach. Qualitative data will be used for a thematic analysis of collaborative governance. Quantitative data from validated questionnaires will be analyzed to measure relational coordination and teamwork, care experience, clinical outcomes, and health-related health-related quality of life, as well as a cost analysis of service utilization. Associations between context, governance mechanisms, and outcomes will be sought. Robust data will be produced to support decision-makers to guide network governance towards optimized clinical outcomes and the reduction of the economic toxicity of cancer for PLCs and health systems.

The future of clinical trials in urological oncology

Well-designed clinical trials in urological oncology help to guide treatment decisions and aid in counselling patients, ultimately serving to improve outcomes. Since the term evidence-based medicine was first used by Gordon Guyatt in 1991, a renewed emphasis on methodology, transparent trial design and study reporting has helped to improve clinical research and in turn, the landscape of medical literature. Novel clinical trial designs (including multi-arm, multistage trials, basket and umbrella studies and research from big data sources, such as electronic health records, administrative claims databases and quality monitoring registries) are well suited to advance innovation in urological oncology. Existing urological clinical trials are often limited by small numbers, are statistically underpowered and many face difficulties with accrual. Thus, efforts to improve trial design are of considerable importance. The development and use of standard outcome sets and adherence to reporting guidelines offer researchers the opportunity to guide value-oriented care, minimize research waste and efficiently identify solutions to the unanswered questions in urology cancer care.

Deep Learning for Natural Language Processing in Urology: State-of-the-Art Automated Extraction of Detailed Pathologic Prostate Cancer Data From Narratively Written Electronic Health Records

PURPOSE

Entering all information from narrative documentation for clinical research into databases is time consuming, costly, and nearly impossible. Even high-volume databases do not cover all patient characteristics and drawn results may be limited. A new viable automated solution is machine learning based on deep neural networks applied to natural language processing (NLP), extracting detailed information from narratively written (eg, pathologic radical prostatectomy [RP]) electronic health records (EHRs).

METHODS

Within an RP pathologic database, 3,679 RP EHRs were randomly split into 70% training and 30% test data sets. Training EHRs were automatically annotated, providing a semiautomatically annotated corpus of narratively written pathologic reports with initially context-free gold standard encodings. Primary and secondary Gleason pattern, corresponding percentages, tumor stage, nodal stage, total volume, tumor volume and diameter, and surgical margin were variables of interest. Second, state-of-the-art NLP techniques were used to train an industry-standard language model for pathologic EHRs by transfer learning. Finally, accuracy of the named entity extractors was compared with the gold standard encodings.

RESULTS

Agreement rates (95% confidence interval) for primary and secondary Gleason patterns each were 91.3% (89.4 to 93.0), corresponding to the following: Gleason percentages, 70.5% (67.6 to 73.3) and 80.9% (78.4 to 83.3); tumor stage, 99.3% (98.6 to 99.7); nodal stage, 98.7% (97.8 to 99.3); total volume, 98.3% (97.3 to 99.0); tumor volume, 93.3% (91.6 to 94.8); maximum diameter, 96.3% (94.9 to 97.3); and surgical margin, 98.7% (97.8 to 99.3). Cumulative agreement was 91.3%.

CONCLUSION

Our proposed NLP pipeline offers new abilities for precise and efficient data management from narrative documentation for clinical research. The scalable approach potentially allows the NLP pipeline to be generalized to other genitourinary EHRs, tumor entities, and other medical disciplines.

Psychometric validation of the German version of the EPIC-26 questionnaire for patients with localized and locally advanced prostate cancer

PURPOSE

For patients with prostate cancer, validated and reliable instruments are essential for measuring patient-reported outcomes. The aim of this study was to validate the German version of the widely established Expanded Prostate Cancer Index Composite with 26 items (EPIC-26).

METHODS

A German translation of the original questionnaire was tested in 3094 patients with localized or locally advanced (any T, any N and M0) prostate cancer with treatment intent (including radical prostatectomy, brachytherapy, active surveillance, watchful waiting). They completed the EPIC-26 questionnaire before treatment. A total of 521 of them also completed a questionnaire 12 months afterward. Internal consistency, sensitivity to change, and construct validity were assessed.

RESULTS

The internal consistency of all domains was sufficient (Cronbach's alpha between 0.64 and 0.93). Item-to-scale correlation coefficients showed acceptable associations between items and their domain score (all > 0.30), with the lowest scores for "bloody stools" (r = 0.37) and "breast problems" (r = 0.32). Confirmatory and exploratory factor analysis confirmed the five-dimension structure of the EPIC-26 (comparative fit index 0.95).

CONCLUSIONS

Psychometric evaluation suggests that the German version of the EPIC-26 is a well-constructed instrument for measuring patient-reported health-related symptoms in patients with prostate cancer.

A prospective study of patient reported urinary incontinence among American, Norwegian and Spanish men 1 year after prostatectomy

Objective

To compare pre- and post-radical prostatectomy (RP) responses in the urinary incontinence domain of Expanded Prostate Cancer Index Composite-26 (EPIC-26) in cohorts from the USA, Norway and Spain.

Methods

A prospective study of pre- and 1-year post-treatment responses in American (n=537), Norwegian (n=520) and Spanish (n=111) patients, establishing the prevalence of urinary incontinence defined according to published dichotomization. Thereafter we focused on the response alternatives “occasional dribbling”, pad use and problem experience. A multivariate logistic regression analysis (significance level ≤ 0.01) considered risk factors for “not retaining total control”.

Results

Compared to the European men, the American patients were younger, healthier and more presented with lower risk tumors. Before RP no inter-country differences emerged the prevalence of urinary incontinence (6%). One-year post-treatment urinary incontinence was described by 30% of the American and 41% of the European patients, occasional dribbling being the most frequent type of urinary leakage. In the multivariate analysis the risk of “not retaining total control” increased almost 3-fold in European compared to American patients, with age and co-morbidity being additional independent risk factor.

Conclusion

After RP patients from Spain and Norway reported more unfavorable outcomes by EPIC-26 than the American patients to most of the urinary incontinence items, the difference between the European and American patients remaining in the multivariate analysis. The most frequent post-RP response alternative “occasional dribbling” needs to be validated with pad weighing as “gold standard”.

Patient-reported sexual quality of life after different types of radical prostatectomy and radiotherapy: Analysis of a population-based prospective cohort

BACKGROUND

Although patients with prostate cancer face many treatment options, to the authors' knowledge the comparative effects of different surgical and radiotherapy (RT) options on sexual function are unclear.

METHODS

In the current study, a population-based cohort of 835 men with newly diagnosed prostate cancer from 2011 through 2013 was recruited throughout North Carolina in collaboration with the Rapid Case Ascertainment system of the North Carolina Central Cancer Registry. All men were enrolled prior to treatment and followed prospectively using the validated Prostate Cancer Symptom Indices (PCSI) instrument. This analysis compares the sexual dysfunction scores of the PCSI among patients who received external-beam RT (EBRT), EBRT with androgen deprivation therapy (ADT), brachytherapy, nerve-sparing radical prostatectomy (RP), and non-nerve-sparing RP. Propensity scores were used to balance patient characteristics across groups, and multiple imputation was used for missing data.

RESULTS

EBRT and brachytherapy resulted in similar PCSI scores through 24 months. Compared with those receiving EBRT, patients treated with EBRT with ADT and RP with or without nerve sparing were found to have worse PCSI scores at all posttreatment time points. Preservation of useful sexual function at 24 months was associated with treatment type, baseline score, and age. Predicted preservation rates were 14.1% to 70.7% for EBRT, 8.4% to 52.3% for EBRT with ADT, 4.7% to 45.3% for nerve-sparing RP, and 4.8% to 34.5% for non-nerve-sparing RP.

CONCLUSIONS

The findings of the current study indicate that RT alone results in the best preservation of sexual function, and brachytherapy provides similar outcomes. RT with ADT and nerve-sparing RP yielded similar outcomes, whereas patients treated with non-nerve-sparing RP experienced the worst sexual function. These results help patients to make decisions among the specific types of surgery and RT they face based on each individual's diagnosis.
