Cost-Effectiveness of Robot-Assisted Radical Cystectomy vs Open Radical Cystectomy for Patients With Bladder Cancer.

Importance: The value to payers of robot-assisted radical cystectomy with intracorporeal urinary diversion (iRARC) when compared with open radical cystectomy (ORC) for patients with bladder cancer is unclear. Objectives: To compare the cost-effectiveness of iRARC with that of ORC. Design, Setting, and Participants: This economic evaluation used individual patient data from a randomized clinical trial at 9 surgical centers in the United Kingdom. Patients with nonmetastatic bladder cancer were recruited from March 20, 2017, to January 29, 2020. The analysis used a health service perspective and a 90-day time horizon, with supplementary analyses exploring patient benefits up to 1 year. Deterministic and probabilistic sensitivity analyses were undertaken. Data were analyzed from January 13, 2022, to March 10, 2023. Interventions: Patients were randomized to receive either iRARC (n = 169) or ORC (n = 169). Main Outcomes and Measures: Costs of surgery were calculated using surgery timings and equipment costs, with other hospital data based on counts of activity. Quality-adjusted life-years were calculated from European Quality of Life 5-Dimension 5-Level instrument responses. Prespecified subgroup analyses were undertaken based on patient characteristics and type of diversion. Results: A total of 305 patients with available outcome data were included in the analysis, with a mean (SD) age of 68.3 (8.1) years, and of whom 241 (79.0%) were men. Robot-assisted radical cystectomy was associated with statistically significant reductions in admissions to intensive therapy (6.35% [95% CI, 0.42%-12.28%]), and readmissions to hospital (14.56% [95% CI, 5.00%-24.11%]), but increases in theater time (31.35 [95% CI, 13.67-49.02] minutes). The additional cost of iRARC per patient was £1124 (95% CI, -£576 to £2824 [US $1622 (95% CI, -$831 to $4075)]) with an associated gain in quality-adjusted life-years of 0.01124 (95% CI, 0.00391-0.01857). The incremental cost-effectiveness ratio was £100 008 (US $144 312) per quality-adjusted life-year gained. Robot-assisted radical cystectomy had a much higher probability of being cost-effective for subgroups defined by age, tumor stage, and performance status. Conclusions and Relevance: In this economic evaluation of surgery for patients with bladder cancer, iRARC reduced short-term morbidity and some associated costs. While the resulting cost-effectiveness ratio was in excess of thresholds used by many publicly funded health systems, patient subgroups were identified for which iRARC had a high probability of being cost-effective.

Critical Appraisal of Decision Models Used for the Economic Evaluation of Bladder Cancer Screening and Diagnosis: A Systematic Review.

BACKGROUND AND OBJECTIVE: Bladder cancer is common among current and former smokers. High bladder cancer mortality may be decreased through early diagnosis and screening. The aim of this study was to appraise decision models used for the economic evaluation of bladder cancer screening and diagnosis, and to summarise the main outcomes of these models. METHODS: MEDLINE via PubMed, Embase, EconLit and Web of Science databases was systematically searched from January 2006 to May 2022 for modelling studies that assessed the cost effectiveness of bladder cancer screening and diagnostic interventions. Articles were appraised according to Patient, Intervention, Comparator and Outcome (PICO) characteristics, modelling methods, model structures and data sources. The quality of the studies was also appraised using the Philips checklist by two independent reviewers. RESULTS: Searches identified 3082 potentially relevant studies, which resulted in 18 articles that met our inclusion criteria. Four of these articles were on bladder cancer screening, and the remaining 14 were diagnostic or surveillance interventions. Two of the four screening models were individual-level simulations. All screening models (n = 4, with three on a high-risk population and one on a general population) concluded that screening is either cost saving or cost effective with cost-effectiveness ratios lower than $53,000/life-years saved. Disease prevalence was a strong determinant of cost effectiveness. Diagnostic models (n = 14) assessed multiple interventions; white light cystoscopy was the most common intervention and was considered cost effective in all studies (n = 4). Screening models relied largely on published evidence generalised from other countries and did not report the validation of their predictions to external data. Almost all diagnostic models (n = 13 out of 14) had a time horizon of 5 years or less and most of the models (n = 11) did not incorporate health-related utilities. In both screening and diagnostic models, epidemiological inputs were based on expert elicitation, assumptions or international evidence of uncertain generalisability. In modelling disease, seven models did not use a standard classification system to define cancer states, others used risk-based, numerical or a Tumour, Node, Metastasis classification. Despite including certain components of disease onset or progression, no models included a complete and coherent model of the natural history of bladder cancer (i.e. simulating the progression of asymptomatic primary bladder cancer from cancer onset, i.e. in the absence of treatment). CONCLUSIONS: The variation in natural history model structures and the lack of data for model parameterisation suggest that research in bladder cancer early detection and screening is at an early stage of development. Appropriate characterisation and analysis of uncertainty in bladder cancer models should be considered a priority.

Elicitation of Health State Utilities Associated with Progression from Bacillus Calmette-Guerin (BCG) Unresponsive Non-muscle Invasive Bladder Cancer (NMIBC).

OBJECTIVES: The treatments for high-grade non-muscle invasive bladder cancer (NMIBC) vary between bladder preserving intravesical approaches and radical cystectomy. The impact of these treatments on health-related quality of life may vary widely. The purpose of this study was to elicit the general public's perspective on quality of life, measured as utility scores associated with treatment for Bacillus Calmette-Guerin (BCG)-unresponsive NMIBC and disease progression, for supporting economic evaluation of newly developed treatments for NMIBC. MATERIALS AND METHODS: Part I involved the development and testing of health states describing NMIBC, which was informed by a rapid review, expert input and a patient advisor. Part II involved elicitation of societal utility values for the different health states. Time trade-off (TTO) interviews were conducted with members of the UK general public. Five health states described different NMIBC scenarios including disease recurrence and progression. Participants ranked each health state, followed by the TTO valuation exercise. Descriptors included NMIBC symptom severity, impact and treatment characteristics. RESULTS: In total, 202 members of the general public participated. The mean age was 46 (standard deviation [SD] 14.6) years. Sample mean (SD) EQ-5D-5L visual analogue scale (VAS) and index scores were 83.2 (12.3) and 0.89 (0.18), respectively. Mean utilities were 0.781 for No High-Grade Recurrence, 0.586 for High-Grade Recurrence, 0.572 for > 1-Year Post-cystectomy and 0.283 for metastatic disease. The First Year Post-cystectomy path health state had a mean utility of 0.288. Pairwise comparisons found statistically significant differences between utilities (p < 0.001), except between High-Grade Recurrence and > 1-Year Post-cystectomy (p = 0.524). There were significant differences in utility scores by age and employment status. CONCLUSION: This study provides utility scores for health states describing living with NMIBC, which is associated with a significant health-related quality-of-life burden. These values address an existing gap in available data and have the potential to be used in models evaluating the cost-effectiveness of both current and newly developed treatments for bladder cancer.

Patient-Reported Outcomes 12 Years after Localized Prostate Cancer Treatment.

BACKGROUND: Long-term patient-reported outcomes are needed to inform treatment decisions for localized prostate cancer. METHODS: Patient-reported outcomes of 1643 randomly assigned participants in the ProtecT (Prostate Testing for Cancer and Treatment) trial were evaluated to assess the functional and quality-of-life impacts of prostatectomy, radiotherapy with neoadjuvant androgen deprivation, and active monitoring. This article focuses on the outcomes of the randomly assigned participants from 7 to 12 years using mixed effects linear and logistic models. RESULTS: Response rates exceeded 80% for most measures. Among the randomized groups over 7 to 12 years, generic quality-of-life scores were similar. Among those in the prostatectomy group, urinary leakage requiring pads occurred in 18 to 24% of patients over 7 to 12 years, compared with 9 to 11% in the active monitoring group and 3 to 8% in the radiotherapy group. In the prostatectomy group, 18% reported erections sufficient for intercourse at 7 years, compared with 30% in the active monitoring and 27% in the radiotherapy groups; all converged to low levels of potency by year 12. Nocturia (voiding at least twice per night) occurred in 34% in the prostatectomy group compared with 48% in the radiotherapy group and 47% in the active monitoring group at 12 years. Fecal leakage affected 12% in the radiotherapy group compared with 6% in the other groups by year 12. The active monitoring group experienced gradual age-related declines in sexual and urinary function, avoiding radical treatment effects unless they changed management. CONCLUSIONS: ProtecT provides robust evidence about continued impacts of treatments in the long term. These data allow patients newly diagnosed with localized prostate cancer and their clinicians to assess the trade-offs between treatment harms and benefits and enable better informed and prudent treatment decisions.

Critical analysis of quality of life and cost-effectiveness of enhanced recovery after surgery (ERAS) for patient's undergoing urologic oncology surgery: a systematic review.

PURPOSE: Enhanced recovery after surgery (ERAS) protocols have been implemented across a variety of disciplines to improve outcomes. Herein we describe the impact of ERAS on quality of life (QOL) and cost for patients undergoing urologic oncology surgery. METHODS: A systematic literature search using the MEDLINE, Scopus, Clinictrials.gov, and Cochrane Review databases for studies published between 1946 and 2020 was conducted. Articles were reviewed and assigned a risk of bias by two authors and were included if they addressed ERAS and either QOL or cost-effectiveness for patients undergoing urologic oncology surgery. RESULTS: The literature search yielded a total of 682 studies after removing duplicates, of which 10 (1.5%) were included in the review. Nine articles addressed radical cystectomy, while one addressed ERAS and QOL for laparoscopic nephrectomy. Six publications assessed the impact of ERAS on QOL domains. Questionnaires used for assessment of QOL varied across studies, and timing of administration was heterogeneous. Overall, ERAS improved patient QOL during early phases of recovery within the realms of bowel function, physical/social/cognitive functioning, sleep and pain control. Costs were assessed in 4 retrospective studies including 3 conducted in the United States and one from China all addressing radical cystectomy. Studies demonstrated either decreased costs associated with ERAS as a result of decreased length of stay or no change in cost based on ERAS implementation. CONCLUSION: While limited studies are published on the subject, ERAS implementation for radical cystectomy and laparoscopic nephrectomy improved patient-reported QOL during early phases of recovery. For radical cystectomy, there was a decreased or neutral overall financial cost associated with ERAS. Further studies assessing QOL and cost-effectiveness over the entire global period of care in a variety of urologic oncology surgeries are warranted.

The development of the Cystectomy-Pathway Assessment Tool (C-PAT): a concise tool to assess the quality of care in the cystectomy pathway.

OBJECTIVES: To develop and test the psychometric properties of a concise, patient-reported questionnaire, designed to assess key aspects of the radical cystectomy (RC) patient pathway that are important to both patients and clinicians. PATIENTS AND METHODS: Draft items were developed by a consultation with a 13-member expert clinical panel, and the in-depth qualitative analysis of 14 semi-structured interviews with patients who had received RC within the previous 18 months. A further nine cognitive interviews with patients refined the items and ensured they were easy to complete. Pilot testing in 122 patients recruited from five hospitals in England tested the properties of validity and reliability of the resulting 17-item questionnaire. RESULTS: Patients and clinicians identified the following aspects as important for the delivery of quality patient care. These included timely referral and initial test results; an explanation of risk/benefits of treatment; access to a cancer nurse specialist; training and support in stoma management; timely surgery, surgical complications, and timely follow-up. Pilot testing showed missing data was low (≤3% for all items), and between 73% and 89% of the responses to items were the most positive about their care (indicating ceiling effects). Five items were identified using factor analysis as being statistically related (Cronbach's α 0.76, intraclass correlation coefficient test-retest reliability of 0.95) and formed the scored part of the tool 'care and support', scored 0-16. There was insufficient evidence at this stage to show the tool was capable of measuring differences between cancer centres. CONCLUSION: We have developed a questionnaire that captures aspects of quality of care within the RC patient pathway. The results support the validity and reliability of the 17-item Cystectomy-Pathway Assessment Tool (C-PAT). We envisage the tool can be the basis for audit of the patient reported assessment of the quality of care for individual cancer centres.

The Impact of the COVID-19 Pandemic on Genitourinary Cancer Care: Re-envisioning the Future.

CONTEXT: The coronavirus disease 2019 (COVID-19) pandemic necessitated rapid changes in medical practice. Many of these changes may add value to care, creating opportunities going forward. OBJECTIVE: To provide an evidence-informed, expert-derived review of genitourinary cancer care moving forward following the initial COVID-19 pandemic. EVIDENCE ACQUISITION: A collaborative narrative review was conducted using literature published through May 2020 (PubMed), which comprised three main topics: reduced in-person interactions arguing for increasing virtual and image-based care, optimisation of the delivery of care, and the effect of COVID-19 in health care facilities on decision-making by patients and their families. EVIDENCE SYNTHESIS: Patterns of care will evolve following the COVID-19 pandemic. Telemedicine, virtual care, and telemonitoring will increase and could offer broader access to multidisciplinary expertise without increasing costs. Comprehensive and integrative telehealth solutions will be necessary, and should consider patients' mental health and access differences due to socioeconomic status. Investigations and treatments will need to maximise efficiency and minimise health care interactions. Solutions such as one stop clinics, day case surgery, hypofractionated radiotherapy, and oral or less frequent drug dosing will be preferred. The pandemic necessitated a triage of those patients whose treatment should be expedited, delayed, or avoided, and may persist with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in circulation. Patients whose demographic characteristics are at the highest risk of complications from COVID-19 may re-evaluate the benefit of intervention for less aggressive cancers. Clinical research will need to accommodate virtual care and trial participation. Research dissemination and medical education will increasingly utilise virtual platforms, limiting in-person professional engagement; ensure data dissemination; and aim to enhance patient engagement. CONCLUSIONS: The COVID-19 pandemic will have lasting effects on the delivery of health care. These changes offer opportunities to improve access, delivery, and the value of care for patients with genitourinary cancers but raise concerns that physicians and health administrators must consider in order to ensure equitable access to care. PATIENT SUMMARY: The coronavirus disease 2019 (COVID-19) pandemic has dramatically changed the care provided to many patients with genitourinary cancers. This has necessitated a transition to telemedicine, changes in threshold or delays in many treatments, and an opportunity to reimagine patient care to maintain safety and improve value moving forward.

The ProtecT randomised trial cost-effectiveness analysis comparing active monitoring, surgery, or radiotherapy for prostate cancer.

BACKGROUND: There is limited evidence relating to the cost-effectiveness of treatments for localised prostate cancer. METHODS: The cost-effectiveness of active monitoring, surgery, and radiotherapy was evaluated within the Prostate Testing for Cancer and Treatment (ProtecT) randomised controlled trial from a UK NHS perspective at 10 years' median follow-up. Prostate cancer resource-use collected from hospital records and trial participants was valued using UK reference-costs. QALYs (quality-adjusted-life-years) were calculated from patient-reported EQ-5D-3L measurements. Adjusted mean costs, QALYs, and incremental cost-effectiveness ratios were calculated; cost-effectiveness acceptability curves and sensitivity analyses addressed uncertainty; subgroup analyses considered age and disease-risk. RESULTS: Adjusted mean QALYs were similar between groups: 6.89 (active monitoring), 7.09 (radiotherapy), and 6.91 (surgery). Active monitoring had lower adjusted mean costs (£5913) than radiotherapy (£7361) and surgery (£7519). Radiotherapy was the most likely (58% probability) cost-effective option at the UK NICE willingness-to-pay threshold (£20,000 per QALY). Subgroup analyses confirmed radiotherapy was cost-effective for older men and intermediate/high-risk disease groups; active monitoring was more likely to be the cost-effective option for younger men and low-risk groups. CONCLUSIONS: Longer follow-up and modelling are required to determine the most cost-effective treatment for localised prostate cancer over a man's lifetime.

Prospective Assessment of Vesical Imaging Reporting and Data System (VI-RADS) and Its Clinical Impact on the Management of High-risk Non-muscle-invasive Bladder Cancer Patients Candidate for Repeated Transurethral Resection.

BACKGROUND: Vesical Imaging Reporting and Data System (VI-RADS) score is adopted to provide preoperative bladder cancer (BCa) staging. Repeated transurethral resection of bladder tumor (Re-TURBT) is recommended in most of high-risk non-muscle-invasive bladder cancers (HR-NMIBCs) due to possibility of persistent/understaged disease after initial TURBT. No diagnostic tools able to improve patient's stratification for such recommendation exist. OBJECTIVE: To (1) prospectively validate VI-RADS for discriminating between NMIBC and muscle-invasive bladder cancer (MIBC) at TURBT, and (2) evaluate the accuracy of VI-RADS for identifying HR-NMIBC patients who could avoid Re-TURBT and detecting those at higher risk for understaging after TURBT. DESIGN, SETTING, AND PARTICIPANTS: Patients with BCa suspicion were offered multiparametric magnetic resonance imaging (mpMRI) before TURBT. According to VI-RADS, a cutoff of ≥3 to define MIBC was assumed. TURBT reports were compared with preoperative VI-RADS scores to assess accuracy of mpMRI for discriminating between NMIBC and MIBC. HR-NMIBC Re-TURBT reports were compared with preoperatively recorded VI-RADS scores to assess mpMRI accuracy in predicting Re-TURBT outcomes. INTERVENTION: Multiparametric MRI of the bladder before TURBT. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Sensitivity, specificity, positive (PPV) and negative (NPV) predictive values were calculated for mpMRI performance in patients undergoing TURBT and for HR-NMIBC patients candidate for Re-TURBT. Performance of mpMRI was assessed by receiver operating characteristic curve analysis. Ƙ statistics was used to estimate inter- and intrareader variability. RESULTS AND LIMITATIONS: A total of 231 patients were enrolled. Multiparametric MRI showed sensitivity, specificity, PPV, and NPV for discriminating NMIBC from MIBC at initial TURBT of 91.9% (95% confidence interval [CI]: 82.2-97.3), 91.1% (95% CI: 85.8-94.9), 77.5% (95% CI: 65.8-86.7), and 97.1% (95% CI: 93.3-99.1), respectively. The area under the curve (AUC) was 0.94 (95% CI: 0.91-0.97). Among HR-NMIBC patients (n=114), mpMRI before TURBT showed sensitivity, specificity, PPV, and NPV of 85% (95% CI: 62.1-96.8), 93.6% (95% CI: 86.6-97.6), 74.5% (95% CI: 52.4-90.1), and 96.6% (95% CI: 90.5-99.3) respectively, to identify patients with MIBC at Re-TURBT. The AUC was 0.93 (95% CI: 0.87-0.97). CONCLUSIONS: VI-RADS is accurate for discriminating between NMIBC and MIBC. Within HR-NMIBC cases, VI-RADS could, in future, improve the selection of patients who are candidate for Re-TURBT. PATIENT SUMMARY: We investigated the accuracy of Vesical Imaging Reporting and Data System (VI-RADS) score to asses bladder cancer staging before transurethral resection of bladder tumors, and we explored the performance of VI-RADS score as a future preoperative predictive tool for the selection of high-risk non-muscle-invasive bladder cancer patients who are candidate for undergoing early repeated transurethral resection of the primary tumor site.

Staging the Host: Personalizing Risk Assessment for Radical Cystectomy Patients.

CONTEXT: Perioperative and long-term functional and oncologic outcomes following radical cystectomy (RC) for localized bladder cancer remain unchanged despite advances in technique and perioperative management, as well as neoadjuvant and adjuvant therapy. Accurate assessment of a patient's perioperative risk is critical to inform preoperative counseling and determine a patient's fitness for RC. OBJECTIVE: To review and synthesize conventional and novel objective patient-specific risk assessment tools that may be incorporated into clinical practice for perioperative risk prognostication with respect to both postoperative complications and long-term oncologic outcomes, patient counseling, and decision-making when RC is being considered. EVIDENCE ACQUISITION: A collaborative review was performed to synthesize currently available evidence on comorbidity, age, body composition, nutrition, frailty, and geriatric assessments for patients undergoing RC. EVIDENCE SYNTHESIS: Current guidelines recommend that pre-RC risk assessment should take into account age, performance status, and comorbidity. However, conventional comorbidity indices perform inconsistently in accurate assessment of the risk of perioperative complications, prolonged rehabilitation, and long-term oncologic outcomes. Novel metrics including standardized assessments of dependency, comorbidity severity, sarcopenia, malnutrition, physical and cognitive frailty, and comprehensive geriatric assessments may offer more precise estimates of physiologic age and relative vulnerability to adverse outcomes following RC. CONCLUSIONS: Perioperative risk assessment before RC should incorporate objective measures of physiologic age, physical function, nutrition, lean muscularity, and frailty. The use of standardized multidimensional instruments should be encouraged for patients undergoing consideration for RC to identify potentially modifiable risk factors that can be targeted with prehabilitation interventions. Future work is needed to validate the performance of these metrics with respect to predicting perioperative complications and oncologic outcomes and to define and assess the effectiveness of specific prehabilitation interventions to optimize patients before surgery. PATIENT SUMMARY: We review several metrics that doctors can use to measure the risks associated with bladder removal, a major surgical procedure. Moving beyond evaluating a patient's age, the burden of other health problems, and surgeon intuition, these tools may be used to counsel patients regarding their surgical risk, to predict oncologic outcomes, and to help identify potential interventions to improve surgical readiness.

Life after prostate cancer diagnosis: protocol for a UK-wide patient-reported outcomes study.

BACKGROUND: Prostate cancer and its treatment may impact physically, psychologically and socially; affecting the health-related quality of life of men and their partners/spouses. The Life After Prostate Cancer Diagnosis (LAPCD) study is a UK-wide patient-reported outcomes study which will generate information to improve the health and well-being of men with prostate cancer. METHODS AND ANALYSIS: Postal surveys will be sent to prostate cancer survivors (18-42 months postdiagnosis) in all 4 UK countries (n=∼70 000). Eligible men will be identified and/or verified through cancer registration systems. Men will be surveyed twice, 12 months apart, to explore changes in outcomes over time. Second, separate cohorts will be surveyed once and the design will include evaluation of the acceptability of online survey tools. A comprehensive patient-reported outcome measure has been developed using generic and specific instruments with proven psychometric properties and relevance in national and international studies. The outcome data will be linked with administrative health data (eg, treatment information from hospital data). To ensure detailed understanding of issues of importance, qualitative interviews will be undertaken with a sample of men who complete the survey across the UK (n=∼150) along with a small number of partners/spouses (n=∼30). ETHICS AND DISSEMINATION: The study has received the following approvals: Newcastle and North Tyneside 1 Research Ethics Committee (15/NE/0036), Health Research Authority Confidentiality Advisory Group (15/CAG/0110), NHS Scotland Public Benefit and Privacy Panel (0516-0364), Office of Research Ethics Northern Ireland (16/NI/0073) and NHS R&D approval from Wales, Scotland and Northern Ireland. Using traditional and innovative methods, the results will be made available to men and their partners/spouses, the funders, the NHS, social care, voluntary sector organisations and other researchers.

Hexyl aminolevulinate-guided fluorescence cystoscopy in the diagnosis and follow-up of patients with non-muscle-invasive bladder cancer: a critical review of the current literature.

CONTEXT: Controversy exists regarding the therapeutic benefit and cost effectiveness of photodynamic diagnosis (PDD) with 5-aminolevulinic acid (5-ALA) or hexyl aminolevulinate (HAL) in addition to white-light cystoscopy (WLC) in the management of non-muscle-invasive bladder cancer (NMIBC). OBJECTIVE: To systematically evaluate evidence regarding the therapeutic benefits and economic considerations of PDD in NMIBC detection and treatment. EVIDENCE ACQUISITION: We performed a critical review of PubMed/Medline, Embase, and the Cochrane Library in October 2012 according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement. Identified reports were reviewed according to the Consolidated Standards of Reporting Trials (CONSORT) and Standards for the Reporting of Diagnostic Accuracy Studies (STARD) criteria. Forty-four publications were selected for inclusion in this analysis. EVIDENCE SYNTHESIS: Included reports used 5-ALA (in 26 studies), HAL (15 studies), or both (three studies) as photosensitising agents. PDD increased the detection of both papillary tumours (by 7-29%) and flat carcinoma in situ (CIS; by 25-30%) and reduced the rate of residual tumours after transurethral resection of bladder tumour (TURBT; by an average of 20%) compared to WLC alone. Superior recurrence-free survival (RFS) rates and prolonged RFS intervals were reported for PDD, compared to WLC in most studies. PDD did not appear to reduce disease progression. Our findings are limited by tumour heterogeneity and a lack of NMIBC risk stratification in many reports or adjustment for intravesical therapy use in most studies. Although cost effectiveness has been demonstrated for 5-ALA, it has not been studied for HAL. CONCLUSIONS: Moderately strong evidence exists that PDD improves tumour detection and reduces residual disease after TURBT compared with WLC. This has been shown to improve RFS but not progression to more advanced disease. Further work to evaluate cost effectiveness of PDD is required.

EORTC risk tables - their usefulness in the assessment of recurrence and progression risk in non-muscle-invasive bladder cancer in Polish patients.

INTRODUCTION: The assessment of risk of recurrence and progression of bladder cancer (BC) is still rather difficult. We decided to check the rates of the changes mentioned above in the group of the Polish patients after a year-long observation and next to compare them with the results calculated in the European Organisation of Research and Treatment of Cancer (EORTC) risk tables. METHODS: The tested group consisted of 91 patients who underwent transurethral resection of bladder tumour (TURBT). When being diagnosed, 60 cases were in the pTa clinical stage, whereas 30 cases were in T1. The coexisting carcinoma in situ (CIS) was observed in four cases. On the basis of the scores obtained from the EORTC tables, the patients were divided into the groups of low, intermediate or high risk of disease recurrence and progression. RESULTS: Recurrence was noticed in 23 patients (25%), while progression was observed in 11 patients (12.1%). The rate of the observed recurrences proved to be lower than it had been predicted in all the groups, except for one of the intermediate-risk group (score 1- 4). Moreover, the rate of the progressions predicted according to the EORTC risk tables was higher in all the risk groups. CONCLUSIONS: It can be noticed that the rate of real recurrences is lower than expected, whereas the rate of the observed progressions is overestimated. Partly, it could be the result of using a relatively small group of patients for observation and applying a different method of treatment.

Contribution of a single repeat PSA test to prostate cancer risk assessment: experience from the ProtecT study.

OBJECTIVE: To examine whether a single repeat prostate-specific antigen (PSA) helps discriminate cancer from non-cancer-related PSA elevation. METHODS: Men aged 50-70 yr (n=54,087) in a multicentre randomised controlled trial comparing treatments for localised prostate cancer were tested. A total of 4102 (7.6%) with an initial PSA in the range of 3-19.9 ng/ml had repeat measurement (median interval: 50 d) followed by prostate biopsy. The decision to biopsy was based on the first PSA level. The outcome was the presence of prostate cancer on biopsy. RESULTS: Men with a 20% drop in PSA had a lower risk of cancer (odds ratio [OR]=0.43; 95% confidence interval [CI], 0.35-0.52; p<0.001) and high-grade cancer (OR=0.29; 95%CI, 0.19-0.44; p<0.001) compared to the rest of the cohort. The effect of percentage reduction was greater in men aged < or =60 yr than in those >60 yr. (OR for any cancer=1.6; 95%CI, 1.0-2.4; p=0.05; OR for high-grade cancer=2.9; 95%CI, 1.2-6.7; p=0.014). This equated to a risk reduction of high-grade cancer from 4% to 0.5%, 6% to 2%, and 15% to 2% in men < or =60 yr with an initial PSA of 3.0-3.99, 4.0-5.99, and > or =6 ng/ml, respectively. No level of repeat PSA confidently predicted absence of cancer. CONCLUSION: Following an initial PSA of 3.0-19.99 ng/ml in men aged 50-70 yr, repeat PSA within 7 wk allows more accurate risk prediction that may assist in the decision-making as to whether or not to proceed with prostate biopsy.
