Bladder cancer risk stratification with the Oncuria 10-plex bead-based urinalysis assay using three different Luminex xMAP instrumentation platforms. J Transl Med 2024; 22:8. [PMID: 38167321 PMCID: PMC10763405 DOI: 10.1186/s12967-023-04811-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2023] [Accepted: 12/16/2023] [Indexed: 01/05/2024] Open
Abstract
BACKGROUND No single marker of bladder cancer (BC) exists in urine samples with sufficient accuracy for disease diagnosis and treatment monitoring. The multiplex Oncuria BC assay noninvasively quantifies the concentration of 10 protein analytes in voided urine samples to quickly generate a unique molecular profile with proven BC diagnostic and treatment-tracking utility. Test adoption by diagnostic and research laboratories mandates reliably reproducible assay performance across a variety of instrumentation platforms used in different laboratories. METHODS We compared the performance of the clinically validated Oncuria BC multiplex immunoassay when data output was generated on three different analyzer systems. Voided urine samples from 36 subjects (18 with BC and 18 Controls) were reacted with Oncuria test reagents in three 96-well microtiter plates on Day 1, and consecutively evaluated on the LED/image-based MagPix, and laser/flow-based Luminex 200 and FlexMap 3D (all xMAP instruments from Luminex Corp., Austin, TX) on Day 2. The BC assay uses magnetic bead-based fluorescence technology (xMAP, Multi-analyte profiling; Luminex) to simultaneously quantify 10 protein analytes in urine specimens [i.e., angiogenin (ANG), apolipoprotein E (ApoE), carbonic anhydrase IX (CA9), CXCL8/interleukin-8 (IL-8), matrix metalloproteinase-9 (MMP-9), matrix metalloproteinase-10 (MMP-10), serpin A1/alpha-1 anti-trypsin (A1AT), serpin E1/plasminogen activator inhibitor-1 (PAI-1), CD138/syndecan-1 (SDC1), and vascular endothelial growth factor-A (VEGF-A)]. All three analyzers quantify fluorescence signals generated by the Oncuria assay. RESULTS All three platforms categorized all 10 analytes in identical samples at nearly identical concentrations, with variance across systems typically < 5%. While the most contemporary instrument, the FlexMap 3D, output higher raw fluorescence values than the two comparator systems, standard curve slopes and analyte concentrations determined in urine samples were concordant across all three units. Forty-four percent of BC samples registered ≥ 1 analyte above the highest standard concentration, i.e., A1AT (n = 7/18), IL-8 (n = 5), and/or ANG (n = 2), while only one control sample registered an analyte (A1AT) above the highest standard concentration. CONCLUSION Multiplex BC assays generate detailed molecular signatures useful for identifying BC, predicting treatment responsiveness, and tracking disease progression and recurrence. The similar performance of the Oncuria assay across three different analyzer systems supports test adaptation by clinical and research laboratories using existing xMAP platforms. TRIAL REGISTRATION This study was registered at ClinicalTrials.gov as NCT04564781, NCT03193528, NCT03193541, and NCT03193515.

Accurate Documentation Contributes to Guideline-concordant Surveillance of Nonmuscle Invasive Bladder Cancer: A Multisite Department of Veterans Affairs Study. Urology 2023; 181:92-97. [PMID: 37660946 PMCID: PMC10901298 DOI: 10.1016/j.urology.2023.08.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2023] [Revised: 08/09/2023] [Accepted: 08/14/2023] [Indexed: 09/05/2023]
Abstract
OBJECTIVE To determine if accurate documentation of bladder cancer risk was associated with a clinician surveillance recommendation that is concordant with AUA guidelines among patients with nonmuscle invasive bladder cancer (NMIBC). METHODS We prospectively collected data from cystoscopy encounter notes from four Department of Veterans Affairs (VA) sites to ascertain whether they included accurate documentation of bladder cancer risk and a recommendation for a guideline-concordant surveillance interval. Accurate documentation was a clinician-recorded risk classification matching a gold standard assigned by the research team. Clinician recommendations were guideline-concordant if the clinician recorded a surveillance interval that was in line with the AUA guideline. RESULTS Among 296 encounters, 75 were for low-, 98 for intermediate-, and 123 for high-risk NMIBC. 52% of encounters had accurate documentation of NMIBC risk. Accurate documentation of risk was less common among encounters for low-risk bladder cancer (36% vs 52% for intermediate- and 62% for high-risk, P < .05). Guideline-concordant surveillance recommendations were also less common in patients with low-risk bladder cancer (67% vs 89% for intermediate- and 94% for high-risk, P < .05). Accurate documentation was associated with a 29% and 15% increase in guideline-concordant surveillance recommendations for low- and intermediate-risk disease, respectively (P < .05). CONCLUSION Accurate risk documentation was associated with more guideline-concordant surveillance recommendations among low- and intermediate-risk patients. Implementation strategies facilitating assessment and documentation of risk may be useful to reduce overuse of surveillance in this group and to prevent unnecessary cost, anxiety, and procedural harms.

Development of a predictive model for recurrence-free survival in pTa low-grade bladder cancer. Urol Oncol 2023; 41:256.e9-256.e15.

Abstract
BACKGROUND Data on Ta low-grade (LG) non-muscle invasive bladder cancer (NMIBC) have shown that follow-up cystoscopies are normal in 82% and 67% of patients with single and multiple tumors, respectively. OBJECTIVE To develop a predictive model associated with recurrence-free survival (RFS) at 6, 12, 18 and 24 months in TaLG cases that consider the patients' risk aversion. MATERIALS AND METHODS Data from a prospectively maintained database of 202 newly diagnosed TaLG NMIBC patients treated at Scandinavian institutions were used for the analysis. To identify risk groups associated with recurrence, we performed a classification tree analysis. Association between risk groups and RFS was evaluated by Kaplan Meier analysis. A Cox proportional hazard model selected significant risk factors associated with RFS using the variables defining the risk groups. The reported C index for the Cox model was 0.7. The model was internally validated and calibrated using 1000 bootstrapped samples. A nomogram to estimate RFS at 6, 12, 18, and 24 months was generated. The performance of our model was compared to EUA/AUA stratification using a decision curve analysis (DCA). RESULTS The tree classification found that tumor number, tumor size and age were the most relevant variables associated with recurrence. The patients with the worst RFS were those with multifocal or single, ≥ 4cm tumors. All the relevant variables identified by the classification tree were significantly associated with RFS in the Cox proportional hazard model. DCA analysis showed that our model outperformed EUA/AUA stratification and the treat all/none approaches. CONCLUSION We developed a predictive model to identify TaLG patients that benefit from less frequent follow-up cystoscopy schedule based on the estimated RFS and personal recurrence risk aversion.

Reducing the Frequency of Follow-up Cystoscopy in Low-grade pTa Non-muscle-invasive Bladder Cancer Using the ADXBLADDER Biomarker. Eur Urol Focus 2022; 8:1643-1649.

Abstract
BACKGROUND Non-muscle-invasive bladder cancer (NMIBC) is one of the most expensive cancers owing to frequent follow-up cystoscopies for detection of recurrence. OBJECTIVE To assess if the noninvasive ADXBLADDER urine test could permit a less intensive surveillance schedule for patients with low-grade (LG) pTa tumor without carcinoma in situ (CIS) at the previous diagnosis. DESIGN, SETTING, AND PARTICIPANTS In a prospective, double-blind, multicenter study, 629 patients underwent follow-up cystoscopy, transurethral resection of bladder tumor/biopsy of suspect lesions, and ADXBLADDER testing. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Diagnostic test accuracy and decision curve analysis were used to evaluate the impact of ADXBLADDER on decision-making on whether to perform follow-up cystoscopy. The primary endpoint was the negative predictive value (NPV) of ADXBLADDER for detection of high-grade and/or CIS (HG/CIS) recurrence and its impact on reducing unnecessary cystoscopies. RESULTS AND LIMITATIONS ADXBLADDER had sensitivity of 66.7% (95% confidence interval [CI] 34.9-90.1%) and an NPV of 99.15% (95% CI 97.8-99.8%) for detection of HG/CIS recurrence. The probability of HG/CIS recurrence was 5.0% for ADXBLADDER-positive patients and 0.85% for ADXBLADDER-negative patients. For HG/CIS recurrence threshold probabilities between 0.85% and 5.0%, ADXBLADDER yields a net benefit with omission of cystoscopy for ADXBLADDER-negative patients. The corresponding net reduction in unnecessary cystoscopies ranges from 11 to 62 per 100 patients. CONCLUSIONS Patients with LG pTa tumor at the previous diagnosis, for which the risk of HG/CIS recurrence is low and the ADXBLADDER NPV for ruling out HG/CIS recurrence is 99.15%, are ideally suited for a less intensive, personalized follow-up surveillance strategy using ADXBLADDER, with omission of cystoscopy for ADXBLADDER-negative patients. PATIENT SUMMARY ADXBLADDER is a urine test that can predict the probability of recurrence of bladder cancer. Patients diagnosed with low-grade cancer confined to the bladder mucosa are ideally suited for less intensive follow-up using this test, which could reduce unnecessary cystoscopy procedures for those with a negative result, potentially improve quality of life, and reduce overall health care costs.

Abstract
Introduction: We aimed to develop and compare the utility of an automated registry of all patients undergoing surveillance for non-muscle invasive bladder cancer (NMIBC) during the severe acute respiratory virus coronavirus 2 (SARS-CoV-2) pandemic. Methods: We populated an electronic register of all patients undergoing bladder tumour surveillance (July–September 2019). The computerised ‘traffic-light’ system was implemented in September 2019 marking the beginning of phase 2. The register was audited at two- and six-months intervals during phase 2 (November 2019 and April 2020). Audit of the system In April 2020 allowed review of care given during the peak of the SARS-CoV-2 pandemic in Ireland. The primary outcome variable was the number of patients who had delayed surveillance cystoscopy in each group. Results: A total of 278 cases were reviewed, 96 in the first cohort and 91 at both intervals of second phase. During the first phase of the audit 17 patients (17.7%) had a missed cystoscopy. Phase 2 showed a sustained decrease in the number of patients with missed surveillance, with eight (8.8%) missing their procedure in both the November and April (SARS-CoV-2) cohorts (17 v. 8, X2 = 10.76, p = 0.0004). Overall, most patients had their procedure done within the recommended time interval (245, 88%). Conclusion: A centralised accessible computerised registry of patients with NMIBC undergoing surveillance is superior to traditional manual surveillance methods, especially during the period of SARS-CoV-2. Going forward we aim to have all patients undergo surveillance within schedule with a long-term goal of a centralised national registry. Level of evidence: Level 2c: “Outcomes Research”.

The Role of Novel Bladder Cancer Diagnostic and Surveillance Biomarkers-What Should a Urologist Really Know? INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19159648.

Abstract
The aim of this review is to analyze and describe the current landscape of bladder cancer diagnostic and surveillance biomarkers. We researched the literature from 2016 to November 2021 to find the most promising new molecules and divided them into seven different subgroups based on their function and location in the cell. Although cystoscopy and cytology are still the gold standard for diagnosis and surveillance when it comes to bladder cancer (BCa), their cost is quite a burden for national health systems worldwide. Currently, the research is focused on finding a biomarker that has high negative predictive value (NPV) and can exclude with a certainty the presence of the tumor, considering missing it could be disastrous for the patient. Every subgroup has its own advantages and disadvantages; for example, protein biomarkers cost less than genomic ones, but on the other hand, they seem to be less precise. We tried to simplify this complicated topic as much as possible in order to make it comprehensible to doctors and urologists that are not as familiar with it, as well as encourage them to actively participate in ongoing research.

Abstract
Objective: COVID-19 has challenged diagnostic and surveillance pathways for suspected and known bladder transitional cell cancer (TCC). Exclusion of high-grade/invasive TCC by molecular urine testing could risk stratify patients for priority flexible cystoscopy and transurethral resection (TUR). We evaluated ADXBladder (ArquerDx), which has a high negative predictive value (NPV) for high-grade and ⩾ pT1 TCC. Patients and methods: Prospective cohort study of patients referred with haematuria for diagnostics or on TCC surveillance (Dec 2020–Feb 2021). Patients underwent ADXBladder testing, flexible cystoscopy and imaging (for haematuria), followed by TUR/biopsy as necessary. Clinico-radiological/pathology findings were compared with ADXBladder results. Results: Of 117 eligible patients, 39 and 78 had positive and negative ADXBladder tests, respectively. Of 15 suspected TCC on cystoscopy, eight were confirmed on TUR/biopsy. Overall ADXBladder NPV was 96.2% (CI: 91.0–98.4). NPV for high-grade and ⩾pT1 TCC was 97.4% (CI: 94.4–98.8) and 98.7% (CI: 95.0–99.7), respectively. Conclusions: Our ‘real world’ evaluation confirmed a high NPV for high grade and ⩾pT1 TCC using ADXBladder. Further larger studies are required to determine whether a negative ADXBladder test combined with negative imaging and patient risk factors may justify patient downgrading on timed diagnostic pathways.

Abstract
IMPORTANCE Low-risk non-muscle-invasive bladder cancer (NMIBC) is associated with extremely low rates of progression and cancer-specific mortality; however, patients with low-risk NMIBC may often receive non-guideline-recommended and potentially costly surveillance testing and treatment. OBJECTIVE To describe current surveillance and treatment practices, cancer outcomes, and costs of care for low-grade papillary stage Ta (low-grade Ta) NMIBC and identify factors associated with increased cost of care. DESIGN, SETTING, AND PARTICIPANTS This population-based cohort study identified 13 054 older adults (aged 66-90 years) diagnosed with low-grade Ta tumors in the Surveillance, Epidemiology and End Results-linked Medicare database from January 1, 2004, through December 31, 2013. Medicare claims data through December 31, 2014, were also reviewed. Data were analyzed from April 1 to October 6, 2021. EXPOSURES Surveillance testing and treatment among patients with low-grade Ta NMIBC. MAIN OUTCOMES AND MEASURES The primary outcome was patterns in population-level surveillance and treatment practice over time among patients with low-grade Ta NMIBC. Secondary outcomes were recurrence (defined as receipt of subsequent transurethral resection of bladder tumor >3 months after index diagnosis of NMIBC and initial transurethral resection of bladder tumor), progression (defined as receipt of definitive treatment for bladder cancer), and costs of care. RESULTS Among 13 054 patients who met inclusion criteria, 9596 (73.5%) were male and 3458 (26.5%) were female, with a median age of 76 years (IQR, 71-81 years). A total of 403 patients (3.1%) were Black, 120 (0.9%) were Hispanic, 12 123 (92.9%) were White, and 408 (3.1%) were of other races and/or ethnicities. Rates of surveillance cystoscopy increased over the study period (from 79.3% in 2004 to 81.5% in 2013; P = .007), with patients receiving a median of 3.0 cystoscopies per year (IQR, 2.0-4.0 per year). Rates of upper tract imaging (particularly computed tomography or magnetic resonance imaging) also increased over the study period (from 30.4% in 2004 to 47.0% in 2013; P < .001), with most patients receiving a median of 2.0 imaging tests per year (IQR, 1.0-2.0 per year). The use of urine cytologic testing or other urine biomarker assessment also increased (from 44.8% in 2004 to 54.9% in 2013; P < .001). Rates of adherence to current guidelines were similar over time (eg, a median of 4398 patients [55.2%] received ≤2 cystoscopies per year in 2004-2008 vs a median of 2736 patients [53.8%] in 2009-2013; P = .11), suggesting overuse of all surveillance testing modalities. With regard to treatment, 2250 patients (17.2%) received intravesical bacillus Calmette-Guérin, and 792 patients (6.1%) received intravesical chemotherapy (excluding receipt of a single perioperative dose). Among all patients with low-grade Ta NMIBC, 217 (1.7%) experienced disease recurrence and 52 (0.4%) experienced disease progression. The total annual median costs of low-grade Ta surveillance testing and treatment increased by 60% (from $34 792 in 2004 to $53 986 in 2013), with higher 1-year median expenditures noted among those with disease recurrence ($76 669) vs no disease recurrence ($53 909) at the end of the study period. CONCLUSIONS AND RELEVANCE In this cohort study, despite low rates of disease recurrence and progression, rates of surveillance testing increased during the study period. The annual cost of care also increased over time, particularly among patients with recurrent disease. Efforts to improve adherence to current practice guidelines, with the focus on limiting overuse of surveillance testing and treatment, may mitigate associated increasing costs of care.

Diagnostic Accuracy of Novel Urinary Biomarker Tests in Non-muscle-invasive Bladder Cancer: A Systematic Review and Network Meta-analysis. Eur Urol Oncol 2021; 4:927-942. [PMID: 34753702 DOI: 10.1016/j.euo.2021.10.003] [Citation(s) in RCA: 38] [Impact Index Per Article: 12.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Revised: 09/23/2021] [Accepted: 10/05/2021] [Indexed: 02/01/2023]
Abstract
CONTEXT During the past decade, several urinary biomarker tests (UBTs) for bladder cancer have been developed and made commercially available. However, none of these is recommended by international guidelines so far. OBJECTIVE To assess the diagnostic estimates of novel commercially available UBTs for diagnosis and surveillance of non-muscle-invasive bladder cancer (NMIBC) using diagnostic test accuracy (DTA) and network meta-analysis (NMA). EVIDENCE ACQUISITION PubMed, Web of Science, and Scopus were searched up to April 2021 to identify studies addressing the diagnostic values of UBTs: Xpert bladder cancer, Adxbladder, Bladder EpiCheck, Uromonitor and Cxbladder Monitor, and Triage and Detect. The primary endpoint was to assess the pooled diagnostic values for disease recurrence in NMIBC patients using a DTA meta-analysis and to compare them with cytology using an NMA. The secondary endpoints were the diagnostic values for high-grade (HG) recurrence as well as for the initial detection of bladder cancer. EVIDENCE SYNTHESIS Twenty-one studies, comprising 7330 patients, were included in the quantitative synthesis. In most of the studies, there was an unclear risk of bias. For NMIBC surveillance, novel UBTs demonstrated promising pooled diagnostic values with sensitivities up to 93%, specificities up to 84%, positive predictive values up to 67%, and negative predictive value up to 99%. Pooled estimates for the diagnosis of HG recurrence were similar to those for the diagnosis of any-grade recurrence. The analysis of the number of cystoscopies potentially avoided during the follow-up of 1000 patients showed that UBTs might be efficient in reducing the number of avoidable interventions with up to 740 cystoscopies. The NMA revealed that diagnostic values (except specificity) of the novel UBTs were significantly higher than those of cytology for the detection of NMIBC recurrence. There were too little data on UBTs in the primary diagnosis setting to allow a statistical analysis. CONCLUSIONS Our analyses support high diagnostic accuracy of the studied novel UBTs, supporting their utility in the NMIBC surveillance setting. All of these might potentially help prevent unnecessary cystoscopies safely. There are not enough data to reliably assess their use in the primary diagnostic setting. These results have to be confirmed in a larger cohort as well as in head-to-head comparative studies. Nevertheless, our study might help policymakers and stakeholders evaluate the clinical and social impact of the implementation of these tests into daily practice. PATIENT SUMMARY Novel urinary biomarker tests outperform cytology with the potential of improving routine clinical practice by preventing unnecessary cystoscopic examinations during the surveillance of non-muscle-invasive bladder cancer.

Abstract
BACKGROUND: Bladder cancer surveillance is invasive, intensive and costly. Patients with low grade intermediate risk non-muscle invasive bladder cancer (NMIBC) are at high risk of recurrence. OBJECTIVE: The objective of this model is to compare the cost of a strategy to alternate surveillance with cystoscopy and a urine marker, Bladder EpiCheck, to standard surveillance. METHODS: A decision tree model was built using TreeAge Pro Healthcare to compare standard surveillance (Standard) with a modified surveillance incorporating Bladder EpiCheck. The model was based on 2 years of surveillance. Outcomes were obtained from literature. Costs were obtained from US and 9 European countries. Sensitivity analyses were performed. RESULTS: The efficacy of the model was equivalent in terms of recurrence for each arm with median recurrence rate of 22%. When setting marker price at 200 local currency, the marker arm was less expensive in the USA, Netherlands, Switzerland, Belgium, Italy, Austria and UK by 154€ to 329£ per patient, for a 2-year period. Cost was higher in France, Spain, and Germany by 33–103€. Cost parity was achieved with marker price between 148€ and $421. Marker cost and specificity have the greatest impact on the overall model cost. CONCLUSIONS: A strategy alternating the urine marker Bladder EpiCheck with cystoscopy in the surveillance of patients with low grade intermediate risk bladder cancer is cost equivalent in the US and European countries when the marker is priced 148€ –$421, as a result of the marker’s high specificity (86%). Prospective studies will be necessary to validate these findings.

Abstract
Background The aim of this systematic review was to identify the current endoscopic surveillance strategies in use across the world and to determine whether these were sufficient or if any recommendations for changes in the guidelines could be made. This review focused on the cystoscopic follow-up of non-muscle invasive bladder cancer (NMIBC) patients and muscle invasive bladder cancer (MIBC) patients who had undergone bladder sparing treatments. Methods A literature search was carried out on Medline and Embase using OVID gateway according to a pre-defined protocol. Systematic screening of the identified studies was carried out by two authors. Quality assessment was performed using the Joanna Briggs critical appraisal tools. Data was extracted on various aspects including the follow-up regime utilised, patients included, outcomes investigated and a summary of the results. The studies were compared in a narrative nature. Results A total of 2,604 studies were identified from the search strategy, of which 14 were deemed suitable for inclusion following the screening process. The studies identified were from nine countries and were mainly observational or qualitative. There was a huge variation in the follow-up regimes utilised within the studies with no clear consensus as to which regime was the most suitable. However, all studies utilised an initial cystoscopy at three months post-TURBT. No studies were identified which investigated the endoscopic follow-up strategies for MIBC patients who opted for bladder conservation with chemoradiation. Conclusions There is no universally accepted protocol for endoscopic follow-up of patients with NMIBC bladder cancer. Guidance on cystoscopic monitoring of bladder in patients who have undergone chemoradiation for MIBC is also lacking.

Abstract
Patients with non-muscle invasive bladder cancer (NMIBC) have high recurrence and progression rates in spite of tumor resection and adjuvant instillation therapy. To detect recurrences and progression, these patients remain under frequent follow-up. Follow-up, however, is not well defined. Frequency and duration of follow recommendations are based on low levels of evidence, which is illustrated by clear differences in these recommendations per guideline, even when specified per risk group. Additionally, follow-up is recommended with cystoscopy and cytology in selected patients, which both have clear limitations. Fact is that follow-up in NMIBC is too frequent, with low levels of evidence and suboptimal tools, and it is patient unfriendly and costly. Improved cystoscopy techniques are unproven or impractical in the outpatient follow-up setting. Urinary markers have been around for decades, but never widely used in clinical practice. New (epi)genetic markers, however, could play a significant role in future follow-up of NMIBC. They have been shown to have very high negative predictive values for recurrences in follow-up of NMIBC, especially high-grade recurrences. Several studies suggested that these markers could be used to adapt follow-up cystoscopy frequency. What still needs study and confirmation is the cost-effectiveness of the use of these markers, which is highly dependent on health care costs per country and marker price. In all, however, implementation of these new urinary markers after confirmation of current results might significantly reduce patient burden and health care costs in the near future without reducing quality.

Abstract
PURPOSE OF REVIEW Patients with nonmuscle invasive bladder cancer (NMIBC) have a high risk of recurrent tumors, even in spite of contemporary guideline recommended therapy. Follow-up recommendations are also clear (cystoscopy with cytology and upper urinary tract imaging in high-risk patients), but frequency and duration of follow-up are well defined. However, recent developments in follow-up tools might be of interest for clinical practice. RECENT FINDINGS Enhanced endoscopy improves detection and treatment of recurrences, and it can help in tailoring follow-up. However, it remains an invasive procedure. Most recently cystoscopy augmented with artificial intelligence has shown some promising results. Active surveillance, frequently done in prostate cancer patients, is also gaining attention in NMIBC follow-up. Finally markers are being studied and launched. Although not recommended by guidelines, and not used in clinical practice, recent studies have shown marker combinations with very high negative predictive values for (high risk) recurrences in follow-up of NMIBC patients. SUMMARY New tools for follow-up such as enhanced cystoscopy and urinary markers might help to individualize follow-up, which will result in decreasing patient discomfort, workload and costs while quality of care is maintained.

Abstract
BACKGROUND Nonmuscle-invasive bladder cancer (NMIBC) has heterogeneous recurrence and progression outcomes. Available risk calculators estimate recurrence and progression but do not predict the recurrence stage or grade, which may influence downstream treatment. The objective of this study was to predict risk-stratified NMIBC recurrence and progression based on recurrence tumor classification and grade. METHODS In total, 2956 patients with NMIBC (<T2) who were diagnosed at Kaiser Permanente Northwest and Geisinger from 1994 to 2015 were identified. Recurrences were annotated for tumor classification and grade. Four risk-stratified outcomes were created based on the tumor classification and grade of the recurrence: 1) any recurrence, 2) intermediate-risk recurrence (Ta high grade, carcinoma in situ, T1 low grade) or higher, 3) high-risk recurrence (T1 high grade) or progression (clinical T2), and 4) progression. Multivariable Cox proportional hazards regression was used to compute 1-year and 5-year risk estimates for each outcome based on initial tumor classification and grade. RESULTS Over a median follow-up of 29.4 months, there were 1062 recurrences (35.9%), including 111 progressions (3.8%). The adjusted hazard of high-risk recurrence or progression increased, depending on initial tumor classification and grade: The adjusted hazard ratio was 2.60 (95% CI, 1.62-4.15) for Ta high-grade tumors, 4.74 (95% CI, 3.01-7.47) for tumor in situ or Ta with carcinoma in situ, and 7.14 (95% CI, 4.97-10.26) T1 high-grade tumors. Using Ta high-grade tumors as an example, the 1-year and 5-year predicted rates of adjusted risk of a high-risk recurrence or progression were 4.4% and 7.9%, respectively. CONCLUSIONS The 1-year and 5-year predicted risk of high-risk recurrences and progression increased with higher tumor classification and grade at diagnosis. These granular risk estimates may further inform risk-stratified treatment and surveillance for patients with NMIBC.

Abstract
PURPOSE Many patients living with bladder cancer do not undergo surveillance that is aligned with their risk for recurrence or progression, which exposes them to unnecessary risk and burden of procedures. To implement risk-aligned surveillance as recommended by multiple guidelines, we need to understand patient-, provider-, and system-level factors contributing to the delivery of risk-aligned surveillance. In this study, we sought to systematically assess patient-level factors. PARTICIPANTS AND METHODS Guided by the Tailored Implementation for Chronic Diseases framework, we conducted semistructured interviews with 22 patients with bladder cancer undergoing surveillance cystoscopy procedures at three facilities within the Department of Veterans Affairs. Patients were sampled using quantitative data on bladder cancer risk category (low v high) and on surveillance category (aligned v not aligned with cancer risk). Interview transcripts were analyzed using a priori codes from the Tailored Implementation for Chronic Diseases framework. Quantitative and qualitative data were integrated by cross-tabulating determinants across risk and surveillance categories. RESULTS Participants included seven low-risk and 15 high-risk patients; 10 underwent risk-aligned surveillance and 12 did not. In mixed-methods analyses, perception of risk appropriately differed by risk but not by surveillance category. Participants understood the recommended surveillance schedule according to their risk category. Participants emphatically expressed that adhering to providers' recommendations is prudent; intentions to adhere did not vary across risk and surveillance categories. CONCLUSION Participants intended to adhere to providers' recommendations and strongly endorsed the importance of adherence. These findings suggest implementation strategies to improve risk-aligned surveillance may be most effective when targeting provider- and system-level factors rather than patient-level factors.

Abstract
Background Surveilling recurrent urothelial carcinoma (UC) requires frequent cystoscopy, which is invasive, expensive and time-consuming. An accurate urinary biomarker has the potential to reduce the number of cystoscopies required during post-treatment surveillance. Objective To audit the clinical utility of a new surveillance protocol incorporating the Cxbladder Monitor (CxbM) test in real-world practice. Methods Three hospitals implemented a new surveillance protocol. Patients were risk stratified, and then provided urine samples for CxbM testing. Low-risk CxbM-positive patients and all high-risk patients had cystoscopy at 2–3 months. Low-risk CxbM-negative patients had cystoscopy at ~ 12 months. Results 443 CxbM tests were conducted on samples from 309 patients: 257 (83.2%) low-risk and 52 (16.8%) high-risk. No pathology-confirmed recurrences were seen in low-risk CxbM-negative patients (n = 108) during the first post-CxbM cystoscopy undertaken a mean ± SD 10.3 ± 3.9 months after testing. Three recurrences were detected during cystoscopy at 2.7 ± 3.4 months in 53 low-risk CxbM-positive patients. In 49 high-risk patients, 39 (79.6%) were CxbM-negative with no pathology-confirmed recurrences. Ten high-risk patients (20.4%) were CxbM-positive with four confirmed recurrences; 2 high-grade and 2 low-grade. The median time to first cystoscopy was 12.13 (95% CI: 11.97–12.4) months in patients with a CxbM-negative result versus 1.63 (95% CI: 1.13–2.3) months in patients with a CxbM-positive result (p < 0.00001). No positive cases were missed, no patients progressed to invasive or metastatic disease, and no patient died of cancer over 35 months of follow-up. Conclusions CxbM accurately identified a high proportion of patients (77.8%) who were safely managed with only one cystoscopy per year. Including CxbM in the protocol for patient surveillance provided clinical utility by reducing the average number of annual cystoscopies by approximately 39%, thereby sparing patients the potential discomfort and anxiety, without compromising detection rates. No advantage was observed for risk stratification prior to CxbM.
