Abstract
Urine cytology is a noninvasive, widely used diagnostic tool for screening and surveillance of genitourinary tract neoplasms. However, the absence of unified terminology and clear objective morphological criteria limits the clinical benefit of urine cytology. The Paris System for Reporting Urine Cytology (TPS) was developed with the goal of standardizing reporting and improving urine cytology performance in detecting high-grade malignancy (HGM). We aimed to evaluate potential effects of TPS on improving urine cytology diagnostic performance and clinical utility by conducting a systematic review and meta-analysis. We searched six electronic databases to identify cross-sectional and cohort studies written in English assessing the accuracy of urine cytology in detecting genitourinary tract malignancies of patients under surveillance or with clinical suspicion of malignancy from January 2004 to December 2022. We extracted relevant data from eligible studies to calculate relative distribution of cytology diagnostic categories; ratio of atypical to HGM cytology diagnosis; and risk of HGM (ROHGM) and HGM likelihood ratio (HGM-LR) associated with cytology diagnostic categories. We used a generalized linear mixed model with logit transformation to combine proportions and multilevel mixed-effect logistic regression to pool diagnostic accuracy measurements. We performed meta-regression to evaluate any significant difference between TPS and non-TPS cohorts. We included 64 studies for 99,796 combined total cytology samples, across 31 TPS and 49 non-TPS cohorts. Pooled relative distribution [95% confidence interval (CI)] of negative for high-grade urothelial carcinoma (NHGUC)/negative for malignancy (NM); atypical urothelial cells (AUC); suspicious for high-grade urothelial carcinoma (SHGUC)/suspicious for malignancy (SM); low-grade urothelial neoplasm (LGUN); and HGM categories among satisfactory cytology cases were 83.8% (80.3%-86.9%), 8.0% (6.0%-10.6%), 2.2% (1.4%-3.3%), 0.01% (0.0%-0.1%), and 4.2% (3.2%-5.5%) in TPS versus 80.8% (76.8-2.7%), 11.3% (8.6%-14.7%), 1.8% (1.2%-2.7%), 0.01% (0.0%-0.1%), and 3.3% (2.5%-4.3%) in non-TPS cohorts. Adopting TPS classification resulted in a significant increase in the frequency of NHGUC and a reduction in AUC cytology diagnoses, respectively. The AUC/HGM ratio in TPS cohort was 2.0, which showed a statistically significant difference from the atypical/HGM ratio of 4.1 in non-TPS cohort (p-value: 0.01). Moreover, the summary rate (95% CI) of LGUN called AUC on cytology significantly decreased to 20.8% (14.9%-28.3%) in the TPS compared with 34.1% (26.4%-42.8%) in non-TPS cohorts. The pooled ROHGM (95% CI) was 20.4% (6.2%-50.0%) in nondiagnostic (NDX), 15.5% (9.6%-24.2%) in NHGUC, 40.2% (30.9%-50.2%) in AUC, 80.8% (72.9%-86.8%) in SHGUC, 15.1% (5.7%-34.3%) in LGUN, and 91.4% (87.3%-94.3%) in HGM categories in TPS studies. NHGUC, AUC, SHGUC, and HGM categories were associated with HGM-LR (95% CI) of 0.2 (0.1-0.3), 0.9 (0.6-1.3), 6.9 (2.4-19.9), and 16.8 (8.3-33.8). Our results suggest that TPS 1.0 has reduced the relative frequency of AUC diagnosis, AUC/HGM ratio, and the frequency of LGUNs diagnosed as AUC on cytology. Adopting this classification has improved the clinical utility of SHGUC and HGM cytology diagnoses in ruling in high-grade lesions. However, an NHGUC diagnosis does not reliably rule out the presence of a high-grade lesion.

Cancer Cytopathol 2024. [PMID: 39003588 DOI: 10.1002/cncy.22884] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2024] [Revised: 06/11/2024] [Accepted: 06/18/2024] [Indexed: 07/15/2024]
Abstract
BACKGROUND This study evaluated the diagnostic effectiveness of the AIxURO platform, an artificial intelligence-based tool, to support urine cytology for bladder cancer management, which typically requires experienced cytopathologists and substantial diagnosis time. METHODS One cytopathologist and two cytotechnologists reviewed 116 urine cytology slides and corresponding whole-slide images (WSIs) from urology patients. They used three diagnostic modalities: microscopy, WSI review, and AIxURO, per The Paris System for Reporting Urinary Cytology (TPS) criteria. Performance metrics, including TPS-guided and binary diagnosis, inter- and intraobserver agreement, and screening time, were compared across all methods and reviewers. RESULTS AIxURO improved diagnostic accuracy by increasing sensitivity (from 25.0%-30.6% to 63.9%), positive predictive value (PPV; from 21.6%-24.3% to 31.1%), and negative predictive value (NPV; from 91.3%-91.6% to 95.3%) for atypical urothelial cell (AUC) cases. For suspicious for high-grade urothelial carcinoma (SHGUC) cases, it improved sensitivity (from 15.2%-27.3% to 33.3%), PPV (from 31.3%-47.4% to 61.1%), and NPV (from 91.6%-92.7% to 93.3%). Binary diagnoses exhibited an improvement in sensitivity (from 77.8%-82.2% to 90.0%) and NPV (from 91.7%-93.4% to 95.8%). Interobserver agreement across all methods showed moderate consistency (κ = 0.57-0.61), with the cytopathologist demonstrating higher intraobserver agreement than the two cytotechnologists across the methods (κ = 0.75-0.88). AIxURO significantly reduced screening time by 52.3%-83.2% from microscopy and 43.6%-86.7% from WSI review across all reviewers. Screening-positive (AUC+) cases required more time than negative cases across all methods and reviewers. CONCLUSIONS AIxURO demonstrates the potential to improve both sensitivity and efficiency in bladder cancer diagnostics via urine cytology. Its integration into the cytopathological screening workflow could markedly decrease screening times, which would improve overall diagnostic processes.

Abstract
PURPOSE Urothelial carcinomas (UCs) are often characterized by frequent recurrences after surgery, making UC one of the costliest cancers. Chromosomal instability (CIN) has been proven to be a hallmark of UCs and is related to the prognosis of many cancer types. In this study, we evaluated CIN of urine sediments as a prognostic indicator for UCs. METHODS Patients with UC were prospectively recruited. Preoperative urine samples were collected for whole genome sequencing and urine cytology tests. Patients underwent standard-of-care treatment and were followed up until disease relapse or study ended. Concordance and accuracy of CIN alone or in combination with cytology in predicting disease relapse were assessed. The value of CIN combined with European Organization for Research and Treatment of Cancer (EORTC) model were also analyzed. RESULTS A total of 137 patients with UCs were included in this study. Median follow-up was 44.2 months and 41.61% patients suffered from cancer relapse. Patients with CIN-high indicated higher relapse rate, and this distinction was significant for patients underwent transurethral resection of bladder tumor (57.89% vs. 34.29%, P = 0.016). Combination of cytology and CIN result could further classified patients into subgroups with distinct relapse risks. Meanwhile, the combination of CIN and EORTC model significantly improved the prediction accuracy compared with EORTC alone (Harrel's C-index: 0.71 vs. 0.65). CONCLUSION CIN level of preoperative urine exfoliated cells had robust prognostic value for bladder cancer patients underwent TURBT. The prognostic model by combining CIN and EORTC may help in stratifying patients to optimize follow-up regimen.

Abstract
Genitourinary (GU) system is among the most commonly involved malignancy sites in the human body. Imaging plays a crucial role not only in diagnosis of cancer but also in disease management and its prognosis. However, interpretation of conventional imaging methods such as CT or MR imaging (MRI) usually demonstrates variability across different readers and institutions. Artificial intelligence (AI) has emerged as a promising technology that could improve the patient care by providing helpful input to human readers through lesion detection algorithms and lesion classification systems. Moreover, the robustness of these models may be valuable in automating time-consuming tasks such as organ and lesion segmentations. Herein, we review the current state of imaging and existing challenges in GU malignancies, particularly for cancers of prostate, kidney and bladder; and briefly summarize the recent AI-based solutions to these challenges.

Abstract
Aims We aimed to assess the performance of bladder wash cytology (BWC) in daily clinical practice in a pure follow-up cohort of patients previously diagnosed with non-muscle invasive bladder cancer (NMIBC). Materials and methods We analyzed 2064 BWCs derived from 314 patients followed for NMIBC (2003-2016). Follow-up investigations were performed using cystoscopy (CS) in combination with BWC. Patients with suspicious CS and/or positive BWC underwent bladder biopsy or transurethral resection. BWC was considered positive if malignant or suspicious cells were reported. Sensitivity (Sn) and specificity (Sp) were calculated for the entire cohort and separately for low-grade (LG) and high-grade (HG) tumors, and carcinoma in situ (CIS) subgroups. Results A total of 95 recurrences were detected, of which only three were detected by BWC alone. Overall, Sn and Sp of BWC were 17.9% and 99.5%, respectively. For LG disease, these numbers were 14.0% and 100%, and for HG disease, these were 22.2% and 99.1%, respectively. For patients with CIS at initial diagnosis, Sn and Sp were 11.0% and 71.4%, respectively. For isolated primary CIS, Sn was 50.0%, and Sp was 98.2%. Conclusion Routine use of BWC in the follow-up for NMIBC is of limited value even in HG tumors. In the presence of isolated primary CIS, adjunct BWC might be justified.

Abstract
Purpose Cystoscopy (rigid/flexible [FC]) is the standard surveillance tool for non-muscle invasive bladder cancer (NMIBC). Nevertheless, it has its drawbacks. The objective of this study is to evaluate the performance of microscopic hematuria (MH), abdominal ultrasonography (US), and urine cytology (UC) as potential substitutes for FC in patients with T1-low-grade (T1-LG) NMIBC. Methods Over a 12-month period, patients attending our tertiary referral center for T1-LG NMIBC follow-up underwent urine analysis for MH and UC, and then US and FC were performed as outpatient surveillance procedures. Those with positive findings underwent inpatient rigid cystoscopy under anesthesia and biopsy. The negative predictive values (NPV) and sensitivity of different combinations of MH, UC, US, and FC were compared with the standard histopathology. Results In 218 evaluated patients, FC had the highest NPV (97.9%). However, this figure showed no statistically significant difference if compared with the combination of negative MH and US (93.8%) (difference = 0.04, p = 0.1) or the combination of MH, US, and UC (94.9%) (difference = 0.03, p = 0.2). The reported sensitivity results were similarly comparable between FC (94.2%) and the aforementioned combinations (90.4% and 92.3%; differences: 0.038 and 0.019; p = 0.4 and 0.7, respectively). Conclusions During the surveillance of NMIBC for patients diagnosed with T1-LG disease, the combination of MH/US has comparable sensitivity and NPV with FC. This non-invasive combination could be considered the first station that might preclude the need for FC in a considerable percentage of this group of patients.

Abstract
OBJECTIVE To describe the risk of multiple recurrences in intermediate-risk non-muscle invasive bladder cancer (IR-NMIBC) and their impact on progression. Prognostic studies of IR-NMIBC have focused on initial recurrences, yet little is known about subsequent recurrences and their impact on progression. MATERIALS AND METHODS IR-NMIBC patients from the Be-Well Study, a prospective cohort study of NMIBC patients diagnosed from 2015 to 2019 at Kaiser Permanente Northern California, were identified. The frequency of first, second, and third intravesical recurrences of urothelial carcinoma were characterized using conditional Kaplan-Meier analyses and random-effects shared-frailty models. The association of multiple recurrences with progression was examined. RESULTS In 291 patients with IR-NMIBC (median follow-up 38 months), the 5-year risk of initial recurrence was 54.4%. After initial recurrence (n = 137), 60.1% of patients had a second recurrence by 2 years. After second recurrence (n = 70), 51.5% of patients had a third recurrence by 3 years. In multivariable analysis, female sex (Hazard Ratio 1.51, P< .01), increasing tumor size (HR 1.14, P< .01) and number of prior recurrences (HR 1.24, P< .01) were associated with multiple recurrences; whereas maintenance BCG (HR 0.66, P = .03) was associated with reduced recurrences. The 5-year risk of progression varied significantly (P< .01) by number of recurrences: 9.5%, 21.9%, and 37.9% for patients with 1, 2, and 3+ recurrences, respectively. CONCLUSIONS Multiple recurrences are common in IR-NMIBC and are associated with progression. Female sex, larger tumors, number of prior recurrences, and lack of maintenance BCG were associated with multiple recurrences. Multiple recurrences may prove useful as a clinical trial endpoint for IR-NMIBC.

[PMID: 36656398 DOI: 10.1007/s10103-023-03708-2] [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: 06/03/2022] [Accepted: 01/11/2023] [Indexed: 01/20/2023]
Abstract
To compare the safety and efficacy of en bloc resection of non-muscle-invasive bladder cancer (NMIBC) using a 1470-/980-nm dual-wavelength laser (DwLRBT) compared to the gold standard, transurethral resection (TURBT). The study group included 251 patients with a confirmed diagnosis of NMIBC, 97 in the DwLRBT group and 154 in the TURBT group. Clinical characteristics, complications, and recurrence-free survival were compared between the two groups. There were no differences between the two groups with regard to age, sex, mean tumor size, mean tumor number, tumor location, risk, fever, and reoperation. Compared to TURBT, DwLRBT was associated with a shorter hospitalization time (mean±standard deviation: 5.81±1.48 days vs. 4.96±1.32, respectively, p=0.001), shorter catheterization time (4.98±1.47 vs. 4.20±1.48 days, respectively; p=0.035), and smaller volume of intraoperative bleeding (8.43±6.21 ml vs. 6.15±5.08, respectively; p=0.003). Recurrence-free survival (RFS) was better for DwLRBT than TURBT in the overall cohort (hazard ratio [HR], 0.4323; 95% confidence interval [CI], 0.2852-0.6554; p=0.0004) and for the following subgroups and tumor types: intermediate-risk (HR, 0.2654; 95%CI, 0.1020-0.6904; p=0.0245) and high-risk (HR, 0.4461; 95% CI, 0.2778-0.7162; p=0.0027) groups; and for pedunculate bladder tumors (HR, 0.4158; 95%CI, 0.2401-0.7202; p=0.0063), single bladder tumors (HR, 0.4136; 95%CI, 0.2376-0.7293; p=0.0072), and multiple bladder tumors (HR, 0.2727; 95%CI, 0.1408-0.5282; p=0.0014). DwLRBT is associated with better operative and postoperative outcomes, including, importantly, a longer RFS, compared to TURBT.

Abstract
Although cystoscopic biopsy is the standard of care for initial diagnosis and local staging of bladder cancer, radiologic imaging plays a major role in identifying local invasion, nodal status, distant metastasis, and posttreatment surveillance. Recent development of the Vesical Imaging-Reporting and Data System for interpretation of multiparametric magnetic resonance imaging of the bladder has expanded the role diagnostic imaging in the management of bladder cancer. This article reviews multimodality imaging appearances, staging, and differential diagnosis of bladder cancer.

Abstract
OBJECTIVES To evaluate overall and recurrence-progression rate-adjusted concordance of treatment prescription in non-muscle-invasive bladder cancer (NMIBC) of an app based on the best available scientific evidence and the urologist's opinion. METHODS Development of an app (APPv) specifically designed for the treatment and follow-up of NMIBC and validation of the proposed APPv treatment endpoint by means of a prospective double-blind observational concordance study of related samples in 100 patients with initial or successive histological diagnosis of NMIBC. RESULTS The treatment prescribed by the urologist agrees with that proposed by the APPv in 64% of cases (kappa index 0.55, P < 0.0001). Regarding low risk, the agreement is 77% (kappa 0.55, P = 0.002), 63% (kappa 0.52, P < 0.0001) for intermediate risk, 17% (kappa 0.143, P = 0.014) in high risk and 66% (kappa 0.71, P = 0.01) for very high risk. Of patients receiving adjuvant intravesical treatment according to APPv, 89.1% remain free of recurrence vs. 61.1% of those with disagreement (P = 0.0004), with a RR 0.46 (95%CI: 0.25-0.86) vs. RR 2.4 (95%CI: 1.5-3.8, P = 0.001). In the APPv-urologist agreement group, 100% of patients are free of progression and 88.9% in the disagreement group (P = 0.004) with a RR 1 vs. RR 1.125 (95%CI: 1-1.26, P = 0.004). CONCLUSIONS APPv can improve adherence to treatment recommendations according to clinical practice guidelines and health outcomes at NMIBC.

Abstract
Simple Summary To detect bladder cancer (BC), urinary cytology and cystoscopy are the primary diagnostic tests used. Urine cytology is non-invasive, easy to collect, with medium sensitivity and high specificity. It is an effective way to detect high-grade BC, but it is less effective on low-grade BC because the rate of equivocal results is much higher, making them difficult to detect. Despite the implementation of new diagnostics, urinary cytology and cystoscopy remain the gold standard. Instead of looking for new diagnostics, one of the new research areas is the improvement of urinary cytology. Recently, the fluorescent properties of plasma membranes of urothelial tumor cells, called peri-membrane fluorescence, found in urinary cytology have been shown to be useful in improving the early detection of BC. The main objective of this study was to characterize the peri-membrane fluorescence allowing the detection of urothelial tumor cells in urine. Abstract Urine cytology is non-invasive, easy to collect, with medium sensitivity and a high specificity. It is an effective way to detect high-grade bladder cancer (BC), but it is less effective on low-grade BC because the rate of equivocal results is much higher. Recently, the fluorescent properties of plasma membranes of urothelial tumor cells (UTC) found in urine cytology have been shown to be useful in improving the early detection of BC. This phenomenon is called peri-membrane fluorescence (PMF). Based on previous studies that have identified the PMF on UTCs, the main objective was to characterize this phenomenon. For this study, a software was specially created to quantify the PMF of all tested cells and different treatments performed. PMF was not found to be a morphological and discriminating feature of UTCs, all cells in shape and not from urine show PMF. We were able to highlight the crucial role of plasma membrane integrity in the maintenance of PMF. Finally, it was found that the induction of a strong cellular stress induced a decrease in PMF, mimicking what was observed in non-tumor cells collected from urine. These results suggest that PMF is found in cells able to resist this stress, such as tumor cells.

Abstract
Bladder cancer is the most common malignancy of the urinary tract. Cystoscopy represents the gold standard in the diagnosis of suspicious bladder lesions. However, the procedure is invasive and burdened by pain, discomfort and infective complications. Cytology, which represents an alternative diagnostic possibility is limited by poor sensitivity. Considering the limitations of both procedures, and the necessity to perform multiple evaluations in patients who are in follow-up for bladder cancer, an improved non-invasive methodology is required in the clinical management of this disease. Liquid biopsy, e.g. the detection of clinical biomarkers in urine, represent a promising novel and non-invasive approach that could overcome those limitations and be integrated into the current clinical practice. The aim of this review is to summarize the state of the art of this approach and the latest novelties regarding detection, prognosis and surveillance of bladder cancer.

Abstract
PURPOSE For many patients with cancer, the frequency of surveillance after primary treatment depends on the risk for cancer recurrence or progression. Lack of risk-aligned surveillance means too many unnecessary surveillance procedures for low-risk patients and not enough for high-risk patients. Using bladder cancer as an example, we examined whether practice determinants differ between Department of Veterans Affairs sites where risk-aligned surveillance was more (risk-aligned sites) or less common (need improvement sites). METHODS We used our prior quantitative data to identify two risk-aligned sites and four need improvement sites. We performed semistructured interviews with 40 Veterans Affairs staff guided by the Tailored Implementation for Chronic Diseases framework that were deductively coded. We integrated quantitative data (risk-aligned site v need improvement site) and qualitative data from interviews, cross-tabulating salient determinants by site type. RESULTS There were 14 participants from risk-aligned sites and 26 participants from need improvement sites. Irrespective of site type, we found a lack of knowledge on guideline recommendations. Additional salient determinants at need improvement sites were a lack of resources ("the next available without overbooking is probably seven to eight weeks out") and an absence of routines to incorporate risk-aligned surveillance ("I have my own guidelines that I've been using for 35 years"). CONCLUSION Knowledge, resources, and lack of routines were salient barriers to risk-aligned bladder cancer surveillance. Implementation strategies addressing knowledge and resources can likely contribute to more risk-aligned surveillance. In addition, reminders for providers to incorporate risk into their surveillance plans may improve their routines.

Abstract
BACKGROUND Follow-up for non-muscle invasive bladder cancer (NMIBC) is a challenge for urologists that has not been finally resolved. The intensity of follow-up is based on the recurrence and progression behavior of the tumor as well as the patient's individual situation. MATERIALS AND METHODS The following article focuses on the current data situation, the valid German S3 guideline and the available instruments for the detection of relapses and progression, taking into account tumor stages and degree of malignancy. RESULTS Urethrocystoscopy, imaging and urine cytology are generally recommended, but the recommendations appear to be too extensive in the case of so-called intermediate risk profiles. Depending on the situation, urine markers could optimize follow-up, although results from prospective randomized studies are still pending. CONCLUSIONS The current follow-up of NMIBC is invasive, carries the risk of side effects and increases costs. In the absence of scientific evidence, recommendations for follow-up for NMIBC are naturally based on expert opinion. In the opinion of the authors, overdiagnosis is currently taking place particularly in patients with an intermediate risk profile. The first prospective, marker-based studies are ongoing and will be helpful in the near future to improve the data situation relevant to urological practice.

Abstract
INTRODUCTION The emergence of urinary biomarkers for bladder cancer diagnosis could provide a reliable and less invasive diagnostic method. It could be also used as an adjuvant to the current gold standards of cytology and cystoscopy to improve diagnostic accuracy and decrease the percentage of false positives. METHODS We searched PubMed, SCOPUS, and Web of Science up to March 18, 2020. We selected four studies that assessed the diagnostic accuracy of urinary apolipoprotein A1 (ApoA-1) in detecting bladder cancer and met the inclusion and exclusion criteria. Two authors independently extracted the data and performed quality assessment of the studies. RESULTS Four studies with 771 participants were selected; 417 were bladder cancer patients and 354 were controls. Bladder cancer was either transitional cell carcinoma or squamous cell carcinoma, the stages varied between Ta to T3, and the grades varied between G1 and G3. The pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio were 90.7%, 90%, 9.478, 0.1, and 99.424, respectively. Summary receiver operating characteristic curve showed an area under the curve of 0.9544 and Q* index of 0.8965. CONCLUSIONS ApoA-1 showed high sensitivity and specificity, so it could be a useful biomarker in diagnosis of bladder cancer.

Abstract
BACKGROUND Mast cells play a critical role in cancer-associated immunity. We aimed to determine the predictive value of urinary mast cell mediators in patients with non-muscle invasive bladder cancer (NMIBC) treated with Bacillus Calmette-Guérin (BCG) immunotherapy. METHODS In this prospective study, 19 patients who received immunotherapy because of NMIBC (Group 1) and 19 healthy participants (Group 2) were enrolled. Urine samples were collected to assay N-methylhistamine, histamine, and tryptase levels immediately before the first BCG instillation, immediately after the third and sixth instillations, and 4 weeks after the sixth instillation in Group 1 and at a single visit in Group 2. The changes in urinary markers because of BCC response, BCG instillation, and the presence of NMIBC were assessed. RESULTS The average age was 56.1 ± 10.5 years in Group 1 and 52.6 ± 9.7 years in Group 2. Fourteen patients had high-grade Ta tumours and five had T1 tumours. While 12 patients had responded to the BCG, seven patients did not respond to the BCG. There was no correlation between mast cell mediators and BCG response. The N-methylhistamine and histamine levels significantly increased with the onset of immunotherapy, and N-methylhistamine levels significantly decreased when immunotherapy was terminated (P < .05). The pre-BCG estimated marginal mean values of N-methylhistamine were significantly higher in Group 1 than in Group 2 (P < .05). CONCLUSIONS Our study is the first to identify the changes in mast cell mediators with the onset of immunotherapy and in presence of bladder cancer. However, these mediators cannot predict patients' response to immunotherapy.

Abstract
Liquid biopsies are increasingly used for the diagnosis and follow-up of cancer patients. Urine is a body fluid that can be used to detect cancers and others diseases. It is noninvasive and easy to collect. To detect Bladder Cancer (BC), cytology is the first assay used. It is an effective way to detect high grade BC but has a high rate of equivocal results, especially for low grade BC. Furthermore, cystoscopy is used to confirm cytology results and to determine cancer status. Cystoscopy is also effective but highly invasive, and not well accepted by patients, especially for BC follow-up. In this review we survey the numerous assays recently developed in order to diagnose BC at an early stage, and to facilitate the follow-up of patients. We discuss their effectiveness, ease of use, and applications. Finally, we discuss assays that, in the future, could improve the diagnosis and management of BC patients.

Abstract
CONTEXT Management of non-muscle-invasive bladder cancer (NMIBC) is costly and associated with negative health-related quality-of-life effects, in part because of the frequent need for repeated transurethral resections under general/regional anaesthesia. Outpatient-based diathermy or laser ablation is another option, but evidence for its efficacy is mixed and its use is controversial. OBJECTIVE To systematically review evidence regarding the efficacy and safety of outpatient diathermy and laser ablation for the treatment of recurrent NMIBC. EVIDENCE ACQUISITION The EMBASE, MEDLINE/PubMed, and Cochrane Library were searched from inception to June 26, 2020. All studies evaluating the use of diathermy or laser ablation for bladder tumours (new or recurrent) in an outpatient setting under local anaesthetic were included. Two reviewers independently screened all articles, searched the reference lists of retrieved articles, and performed the data extraction. The quality of evidence and risk of bias were assessed using the GRADE and ROBINS-I tools. EVIDENCE SYNTHESIS The search yielded 1328 studies. After excluding duplicates, 1319 titles and abstracts were screened and 17 studies (1584 patients) were eligible for inclusion in the final review. The majority of patients had small, low-grade tumours, but there was heterogeneity in the inclusion criteria. Overall, laser ablation and diathermy resulted in mean recurrence rates of 47% and 32% at follow-up of 22-38 mo, respectively, with a mean progression rate of 3-12% (low certainty of evidence). Both procedures were well tolerated, with low pain scores and low periprocedural complication rates (moderate certainty of evidence). CONCLUSIONS Outpatient diathermy and laser ablation have good short-term efficacy in patients with low-grade NMIBC and reduce the need for intervention under general/regional anaesthesia. The procedures are well tolerated with low complication rates. The overall certainty of evidence is low, with heterogeneity between studies and methodological limitations. However, we have highlighted the need for randomised trials with long-term follow-up using standardised risk classification and outcome measures. Despite these limitations, the findings will aid in patient counselling regarding this less invasive treatment option that avoids the morbidity of transurethral resection. PATIENT SUMMARY Outpatient diathermy and laser ablation have good success rates in treating recurrent low-grade bladder tumours in the short term, avoiding the need for more invasive procedures under general/regional anaesthesia, with low rates of side effects. Further studies are needed to determine whether these treatments remain safe and effective in the long term.

A multimodal molecular imaging approach targeting urokinase plasminogen activator receptor for the diagnosis, resection and surveillance of urothelial cell carcinoma. Eur J Cancer 2021; 146:11-20. [PMID: 33561783 DOI: 10.1016/j.ejca.2021.01.001] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2020] [Revised: 12/22/2020] [Accepted: 01/07/2021] [Indexed: 12/24/2022]
Abstract
With a 5-year recurrence rate of 30-78%, urothelial cell carcinoma (UCC) rates amongst the highest of all solid malignancies. Consequently, after transurethral resection, patients are subjugated to life-long endoscopic surveillance. A multimodal near-infrared (NIR) fluorescence-based imaging strategy can improve diagnosis, resection and surveillance, hence increasing quality of life. METHODS Expression of urokinase plasminogen activator receptor (uPAR) and epithelial cell adhesion molecule (EpCAM) are determined on paraffin-embedded human UCC using immunohistochemistry and on UCC cell lines by flow cytometry. MNPR-101, a humanised monoclonal antibody targeting uPAR is conjugated to IRDye800CW and binding is validated in vitro using surface plasmon resonance and cell-based binding assays. In vivo NIR fluorescence and photoacoustic three-dimensional (3D) imaging are performed with subcutaneously growing human UM-UC-3luc2 cells in BALB/c-nude mice. The translational potential is confirmed in a metastasising UM-UC-3luc2 orthotopic mouse model. Infliximab-IRDye800CW and rituximab-IRDye800CW are used as controls. RESULTS UCCs show prominent uPAR expression at the tumour-stroma interface and EpCAM on epithelial cells. uPAR and EpCAM are expressed by 6/7 and 4/7 UCC cell lines, respectively. In vitro, MNPR-101-IRDye800CW has a picomolar affinity for domain 2-3 of uPAR. In vivo fluorescence imaging with MNPR-101-IRDye800CW, specifically delineates both subcutaneous and orthotopic tumours with tumour-to-background ratios reaching as high as 6.8, differing significantly from controls (p < 0.0001). Photoacoustic 3D in depth imaging confirms the homogenous distribution of MNPR-101-IRDye800CW through the tumour. CONCLUSIONS MNPR-101-IRDye800CW is suitable for multimodal imaging of UCC, awaiting clinical translation.

Diagnostic value of a comprehensive, urothelial carcinoma-specific next-generation sequencing panel in urine cytology and bladder tumor specimens. Cancer Cytopathol 2021; 129:537-547. [PMID: 33539671 DOI: 10.1002/cncy.22410] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2020] [Revised: 11/06/2020] [Accepted: 01/04/2021] [Indexed: 12/25/2022]
Abstract
BACKGROUND Urine cytology can reliably diagnose high-grade urothelial carcinoma (HGUC) but not low-grade urothelial carcinoma (LGUC), and a more sensitive test is needed. Previously, a pilot study highlighted the possible diagnostic utility of next-generation sequencing (NGS) in identifying both LGUC and HGUC in urine cytology specimens. METHODS Twenty-eight urine ThinPrep cytology specimens and preceding or subsequent bladder tumor biopsy/resection specimens obtained within 3 months were included in the study (LGUC, n = 15; HGUC, n = 13). A customized, bladder-specific NGS panel was performed; it covered 69 frequently mutated or altered genes in urothelial carcinoma (UC) that were reported by The Cancer Genome Atlas and the Catalogue of Somatic Mutations in Cancer. RESULTS The sequencing results were compared between the urine cytology specimens and the corresponding bladder tumor biopsies/resections. TP53 was the most frequently identified mutation in HGUC cases (11 of 13 [85%]). PIK3CA and KDM6A were the most frequently identified mutations in LGUC: they occurred in 7 of 15 cases (47%) and in 6 of 15 cases (40%), respectively. Additional frequent mutations identified in the panel included ARID1A (n = 5), EP300 (n = 4), LRP1B (n = 3), ERBB2 (n = 2), STAG2 (n = 2), FGFR3 (n = 3), MLL (n = 2), MLL3 (n = 2), CREBBP1 (n = 1), RB1 (n = 1), and FAT4 (n = 1). Overall, the concordance between the cytology and surgical specimens was 75%. The sensitivity and specificity for identifying mutations in urine cytology specimens were 84% and 100%, respectively. CONCLUSIONS A bladder-specific NGS panel increases the sensitivity and specificity of urine cytology's diagnostic utility in both low- and high-grade tumors and may serve as a noninvasive surveillance method in the follow-up of patients with UC harboring known mutations.

Abstract
The role of immunotherapy in bladder urothelial cancers is rapidly expanding. Since the initial second-line therapy approval for patients who fail prior platinum-based chemotherapy, the use of immunotherapy with checkpoint inhibitors has been rapidly evolving. There are approved indications for first-line metastatic disease in the platinum-ineligible patients or the cisplatin-ineligible PD-L1 positive patients, and there is a label for high-risk non-muscle-invasive bladder cancer who are BCG-refractory. In addition, a trial on maintenance immunotherapy with avelumab showed positive findings with improvement in overall survival that has also changed standard of care for these patients. There are ongoing clinical trials evaluating its use in the neoadjuvant and adjuvant perioperative muscle-invasive bladder cancer setting. The pivotal trials that led to these FDA approvals and promising and ongoing trials are discussed herein.

Abstract
Background Urinary conventional cytology (UCCy) is easy to perform, but its low sensitivity, especially for low-grade urothelial neoplasms (LGUNs), limits its indications in the management of patients at risk of bladder cancer. The authors aim at obtaining a complementary test that would effectively increase the sensitivity of UCCy on voided urines by analyzing fluorescence of Papanicolaou-stained urothelial cells with no change of method in slide preparation. Methods In this retrospective study of 155 patients, 91 Papanicolaou-stained voided urines were considered satisfactory under fluorescence microscopy (FMi). The results of FMi were compared with UCCy (using transmission microscopy) and correlated to cystoscopy, histology and follow-up data. Results The results are given for all patients and for two groups of them according to the patients’ main complaints (group 1: 33 patients followed up for a previously treated bladder tumor; group 2: 58 patients with persistent urinary symptoms). Overall negative predictive value (NPV) and sensitivity of FMi were 100% vs. 73.7% and 64.3% respectively for UCCy (P = 0.0001). Sensitivity of FMi for LGUN was unexpectedly high with a value of 100% vs. 46.2% for UCCy (P = 0.0002). FMi was significantly superior to UCCy for detecting urothelial tumors in every group of patients and would allow a better characterization of atypical urothelial cells (AUCs) defined by the Paris System for Reporting Urine Cytology (TPS). Conclusions Because of its sensitivity and NPV of 100%, FMi could complement UCCy to screen voided urines allowing a better detection of primary urothelial tumors or early recurrences of previously treated urothelial carcinoma. Moreover, this “dual screening” would allow completing efficiently cystoscopy to detect flat dysplasia, carcinoma in situ (CIS) and extra bladder carcinoma.

Refining assessment of response to radiation-based therapy for muscle-invasive bladder cancer: Is post-treatment tumor bed biopsy always necessary? Urol Oncol 2020; 39:299.e7-299.e14. [PMID: 33283758 DOI: 10.1016/j.urolonc.2020.10.001] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2020] [Revised: 09/27/2020] [Accepted: 10/02/2020] [Indexed: 01/27/2023]
Abstract
INTRODUCTION Radiation-based therapy (RT) has emerged as a suitable alternative to radical cystectomy (RC) and pelvic lymph node dissection for muscle-invasive bladder cancer (MIBC) patients. Routine biopsy after RT to rule out residual disease remains inconsistent across guidelines. Our objective was to review the significance of a bladder biopsy in terms of assessment of response post-RT and its potential impact on survival. PATIENTS AND METHODS This was a single-center retrospective study on patients with MIBC (cT2-4aN0-2M0) treated with curative intent RT. A total of 169 patients with primary urothelial carcinoma were analyzed. Patients' demographic, clinical and pathological variables, imaging, cystoscopy, urine cytology, and biopsy reports after RT were collected and compiled. Whenever urine cytology was positive or cystoscopy showed any malignant-appearing lesion, the first assessment post-RT was considered suspicious for residual disease. A descriptive population analysis was reported. Cox regression multivariable analysis was performed to identify independent variables associated with survival outcomes. RESULTS Median age was 75 years (interquartile range 66-82) and clinical staging was cT2 in 152 (90%) patients. Cytology and cystoscopy were normal in 140 (83%) after RT. Of patients with a control biopsy, residual MIBC was present in 3 (5%) and non-MIBC in another 6 (11%). On the contrary, a for-cause biopsy due to a suspicious assessment post-RT did not yield residual cancer in 45% of patients. Multivariable analysis showed that age (hazard ratio [HR] 1.04, P< 0.001), lymphovascular invasion (HR 1.68, P = 0.03) and a suspicious assessment after RT (HR 3.21; P< 0.001) were significantly associated with worse OS. This study was limited by its retrospective design. CONCLUSIONS A routine biopsy after RT may be warranted to assess treatment response. This might be particularly important for patients who may benefit from early surgical intervention for residual MIBC. Further prospective studies are needed to confirm our findings.

Int J Mol Sci 2020; 21:ijms21186542.

Abstract
Recently, there has been a great effort to develop tests based on non-invasive urinary biomarkers (NMIBCs). These tests are based on the fact that NMIBCs are heterogeneous at the molecular level and can be divided into different molecular groups useful to predict prognosis and response to treatment. The assessment of epigenetic alterations, such as DNA methylation, represents a promising cancer biomarker. DNA methylation is an epigenetic modification that affects gene expression without modifying the DNA sequence. Several studies have highlighted the presence of methylated loci in the context of bladder cancer, indicating its potential application as a diagnostic and prognostic biomarker. One of the novel assays based on a DNA methylation profile, the Bladder EpiCheck, analyzes DNA from spontaneous urine, detecting disease-specific DNA methylation patterns in bladder cancer patients. This test, due to its non-invasive nature and highly promising performance could, in future, become an invaluable tool in the follow-up of bladder cancer patients. Potential new applications could include diagnosis and surveillance of upper-tract disease, for the replacement of invasive testing and ureteroscopy.

Abstract
Urothelial carcinoma is a very rare malignancy in the pediatric population. In spite of the extremely low amount of published cases, the incidence rate is between 0.4 and 0.1% before the age of 20. Insomuch that only less than 30 cases have been reported in the first decade. Those tumors were mostly solitary, non-invasive, with low-risk of progression and recurrence rate compared to adult-onset form. In this case report, we aim to discuss the diagnosis and treatment of a 10-year-old male patient with urothelial carcinoma of bladder who admitted to our clinic.

Abstract
BACKGROUND Intermediate-risk non-muscle-invasive bladder cancer (NMIBC) involves heterogeneous patients, resulting in uncertainty regarding its prognosis and the indication of adjuvant therapy. Previous studies suggested a correlation between tumor location, especially bladder neck involvement (BNI), and patient prognosis of NMIBC. OBJECTIVE We investigated the role of BNI in risk substratification of intermediate-risk NMIBC patients. DESIGN, SETTING, AND PARTICIPANTS This single-institutional study included 436 primary or recurrent intermediate-risk NMIBC patients based on risk stratification in the European Association of Urology guidelines. INTERVENTION All patients underwent transurethral resection of the bladder tumor. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The primary and secondary endpoints were progression and recurrence, respectively. The associations of BNI with the endpoints were examined using the Kaplan-Meier method and the Cox proportional hazards model. RESULTS AND LIMITATIONS Overall, 205 (47%) patients had multiple tumors and 276 (63%) underwent intravesical therapy. BNI was observed in 53 (12%) patients. During the median follow-up of 42 mo, 12 (3%) and 211 (48%) patients experienced progression and recurrence, respectively. Multivariate analysis showed that BNI was an independent predictor for both progression (hazard ratio 10.98, p < 0.001) and recurrence (hazard ratio 2.12, p < 0.001). The progression rate was significantly higher in patients with BNI compared with those without BNI (13% vs 1% at 3 yr and 20% vs 1% at 6 yr; p < 0.001). Analogous findings were observed for recurrence. The progression rate was more remarkably stratified by BNI in 103 recurrent cases (17% vs 3% at 3 yr and 34% vs 3% at 6 yr in patients with vs without BNI; p < 0.001). A limitation of this study was its retrospective nature. CONCLUSIONS BNI substratified intermediate-risk NMIBC patients well regarding their risks of progression and recurrence, which could help determine follow-up and therapeutic strategies for these patients. PATIENT SUMMARY The associations of bladder neck involvement with progression and recurrence were evaluated in patients with intermediate-risk non-muscle-invasive bladder cancer. We found that bladder neck involvement was a good factor for substratifying patients based on their risks of progression and recurrence. Bladder neck involvement can be useful in determining follow-up and therapeutic strategies for intermediate-risk non-muscle-invasive bladder cancer.

Abstract
Bladder cancer (BC) ranks as the sixth most prevalent cancer in the world, with a steady rise in its incidence and prevalence, and is accompanied by a high morbidity and mortality. BC is a complex disease with several molecular and pathological pathways, thus reflecting different behaviors depending on the clinical staging of the tumor and molecular type. Diagnosis and monitoring of BC is mainly performed by invasive tests, namely periodic cystoscopies; this procedure, although a reliable method, is highly uncomfortable for the patient and it is not exempt of comorbidities. Currently, there is no formal indication for the use of molecular biomarkers in clinical practice, even though there are several tests available. There is an imperative need for a clinical non-invasive testing for early detection, disease monitoring, and treatment response in BC. In this review, we aim to assess and compare different tests based on molecular biomarkers and evaluate their potential role as new molecules for bladder cancer diagnosis, follow-up, and treatment response monitoring.

Front Genet 2019; 10:1237.

Abstract
Bladder cancer (BC), the most frequent malignancy of the urinary system, is ranked the sixth most prevalent cancer worldwide. Of all newly diagnosed patients with BC, 70-75% will present disease confined to the mucosa or submucosa, the non-muscle-invasive BC (NMIBC) subtype. Of those, approximately 70% will recur after transurethral resection (TUR). Due to high rate of recurrence, patients are submitted to an intensive follow-up program maintained throughout many years, or even throughout life, resulting in an expensive follow-up, with cystoscopy being the most cost-effective procedure for NMIBC screening. Currently, the gold standard procedure for detection and follow-up of NMIBC is based on the association of cystoscopy and urine cytology. As cystoscopy is a very invasive approach, over the years, many different noninvasive assays (both based in serum and urine samples) have been developed in order to search genetic and protein alterations related to the development, progression, and recurrence of BC. TERT promoter mutations and FGFR3 hotspot mutations are the most frequent somatic alterations in BC and constitute the most reliable biomarkers for BC. Based on these, we developed an ultra-sensitive, urine-based assay called Uromonitor®, capable of detecting trace amounts of TERT promoter (c.1-124C > T and c.1-146C > T) and FGFR3 (p.R248C and p.S249C) hotspot mutations, in tumor cells exfoliated to urine samples. Cells present in urine were concentrated by the filtration of urine through filters where tumor cells are trapped and stored until analysis, presenting long-term stability. Detection of the alterations was achieved through a custom-made, robust, and highly sensitive multiplex competitive allele-specific discrimination PCR allowing clear interpretation of results. In this study, we validate a test for NMIBC recurrence detection, using for technical validation a total of 331 urine samples and 41 formalin-fixed paraffin-embedded tissues of the primary tumor and recurrence lesions from a large cluster of urology centers. In the clinical validation, we used 185 samples to assess sensitivity/specificity in the detection of NMIBC recurrence vs. cystoscopy/cytology and in a smaller cohort its potential as a primary diagnostic tool for NMIBC. Our results show this test to be highly sensitive (73.5%) and specific (93.2%) in detecting recurrence of BC in patients under surveillance of NMIBC.

c-Met activation leads to the establishment of a TGFβ-receptor regulatory network in bladder cancer progression. Nat Commun 2019; 10:4349.

Abstract
Treatment of muscle-invasive bladder cancer remains a major clinical challenge. Aberrant HGF/c-MET upregulation and activation is frequently observed in bladder cancer correlating with cancer progression and invasion. However, the mechanisms underlying HGF/c-MET-mediated invasion in bladder cancer remains unknown. As part of a negative feedback loop SMAD7 binds to SMURF2 targeting the TGFβ receptor for degradation. Under these conditions, SMAD7 acts as a SMURF2 agonist by disrupting the intramolecular interactions within SMURF2. We demonstrate that HGF stimulates TGFβ signalling through c-SRC-mediated phosphorylation of SMURF2 resulting in loss of SMAD7 binding and enhanced SMURF2 C2-HECT interaction, inhibiting SMURF2 and enhancing TGFβ receptor stabilisation. This upregulation of the TGFβ pathway by HGF leads to TGFβ-mediated EMT and invasion. In vivo we show that TGFβ receptor inhibition prevents bladder cancer invasion. Furthermore, we make a rationale for the use of combinatorial TGFβ and MEK inhibitors for treatment of high-grade non-muscle-invasive bladder cancers.

Abstract
Tumor follow-up in patients with non-muscle invasive bladder cancer (NMIBC) is a weighing up between the morbidity associated with invasive diagnostics and the risk of tumor recurrence and especially progression. The risk stratification into low, intermediate, and high-risk tumors enables a risk-adapted follow-up. For individual estimation of the risk of progression and recurrence, risk calculators should be used. Follow-up is still based on cystoscopy, which is recommended lifelong for high and intermediate-risk tumors and for up to 5 tumor-free years for low-risk tumors. Urine cytology has a high sensitivity and specificity for high-risk tumors and is recommended in the follow-up care. There is currently no recommendation for any commercially available urinary marker due to inadequate evidence. For the clarification of synchronous and metachronous tumors of the upper urinary tract computed tomography (CT) urography or alternatively magnetic resonance (MR) urography is recommended.

Abstract
The primary care physician should be familiar with renal and bladder cancer risk factors, symptoms, and workup. Bladder cancer generally presents with painless hematuria, which primary care providers may identify. Bladder cancer is treated more successfully when caught early. Patients need support and follow-up through treatment. Renal cell carcinoma is generally asymptomatic and commonly is an incidental finding on abdominal imaging. The workup of incidental renal masses is important and ensure appropriate follow-up and treatment are received. Renal cancer is easier to successfully treat when identified at an early stage, so proper identification is important for appropriate treatment.

Abstract
OBJECTIVES To determine if self-visualization of ambulatory cystoscopy provides a decrease in pain perception in male and female patients. METHODS A quasi-randomized controlled trial involving patients scheduled for ambulatory cystoscopy from August to November 2017. The indications were: hematuria, bladder cancer surveillance, lower urinary tract symptoms, and incontinence. The patients were quasi-randomized into two groups by scheduled date. Both groups received the same explanation before and during cystoscopy. The variables analyzed were gender, age, Visual Analog Scale (VAS) score, number of previous cystoscopies, and indication and positivity of the test for bladder neoplasia. All patients were analyzed by group and gender separately. The statistical tests used were: Wilcoxon rank-sum, Kruskal-Wallis, Mann-Whitney U test, Pearson correlation, and linear regression. RESULTS Four hundred four patients were included (318 males and 86 females) and divided into two groups, group A (no self-visualization, n = 239) and group B (self-visualization, n = 165). In males, mean VAS score was 2.6 for group A and 2.5 for group B (p = 0.276); in females, VAS score was 2.78 for group A and 1.64 for group B (p = 0.008). Regarding the remaining variables analyzed, neither positivity of the test for neoplasia (p = 0.14) nor cystoscopy indication (p = 0.597) had any influence. In patients with two or more previous cystoscopies, a reduction in mean VAS score was seen in both genders. In males having their first cystoscopy the mean VAS score was 3.1 and decreased to 2.1 for the third or more (p = 0.001); in females the mean VAS score was 2.89 for the first and 1.56 for the third or more (p = 0.02), although this benefit tended to disappear when the number of previous cystoscopies was taken into account. CONCLUSION In male patients, self-visualization of cystoscopy did not impact pain perception, while in female patients, it seemed to provide a benefit. The number of previous cystoscopies had an influence, diminishing the perception of pain, regardless of whether the patient visualized the procedure or not.

Abstract
Aims Bladder cancer–specific nuclear matrix protein-4 (BLCA-4) is a protein expressed mainly in bladder cancer tissues. Therefore, the aim of this study was to investigate its assisting diagnostic potential in non-muscle-invasive bladder cancer (NMIBC). Methods Twenty patients with NMIBC, 20 with benign prostatic hyperplasia (BPH), and 20 normal controls were included in this study. Blood and urine samples were collected from all patients. Moreover, cancer foci and adjacent tissue samples were collected from NMIBC patients, and normal bladder tissue samples were collected from patients with BPH. A competitive enzyme-linked immunosorbent assay was used to determine the BLCA-4 level in serum and urine, and immunohistochemistry was used to examine BLCA-4 expression in bladder cancer, adjacent, and normal tissues. Results Median urinary BLCA-4 levels in the NMIBC, BPH, and normal control groups were 0.759 ng/mL, 0.309 ng/mL, and 0.171 ng/mL, respectively. Urinary BLCA-4 level was significantly higher in the NMIBC group than in the other 2 groups (P < 0.01); meanwhile, the BPH group was higher than the normal control group (P < 0.05). Median serum BLCA-4 levels in the NMIBC, BPH, and normal control groups were 5.680 ng/mL, 5.928 ng/mL, and 5.473 ng/mL, respectively, showing no significant difference among groups (P > 0.05). Conclusion As a new marker of bladder cancer, urinary BLCA-4 level detection might apply for clinical diagnosis or postoperative monitoring for NMIBC.

Abstract
IMPORTANCE Cancer care guidelines recommend aligning surveillance frequency with underlying cancer risk, ie, more frequent surveillance for patients at high vs low risk of cancer recurrence. OBJECTIVE To assess the extent to which such risk-aligned surveillance is practiced within US Department of Veterans Affairs facilities by classifying surveillance patterns for low- vs high-risk patients with early-stage bladder cancer. DESIGN SETTING AND PARTICIPANTS US national retrospective cohort study of a population-based sample of patients diagnosed with low-risk or high-risk early-stage bladder between January 1, 2005, and December 31, 2011, with follow-up through December 31, 2014. Analyses were performed March 2017 to April 2018. The study included all Veterans Affairs facilities (n = 85) where both low-and high-risk patients were treated. EXPOSURES Low-risk vs high-risk cancer status, based on definitions from the European Association of Urology risk stratification guidelines and on data extracted from diagnostic pathology reports via validated natural language processing algorithms. MAIN OUTCOMES AND MEASURES Adjusted cystoscopy frequency for low-risk and high-risk patients for each facility, estimated using multilevel modeling. RESULTS The study included 1278 low-risk and 2115 high-risk patients (median [interquartile range] age, 77 [71-82] years; 99% [3368 of 3393] male). Across facilities, the adjusted frequency of surveillance cystoscopy ranged from 3.7 to 6.2 (mean, 4.8) procedures over 2 years per patient for low-risk patients and from 4.6 to 6.0 (mean, 5.4) procedures over 2 years per patient for high-risk patients. In 70 of 85 facilities, surveillance was performed at a comparable frequency for low- and high-risk patients, differing by less than 1 cystoscopy over 2 years. Surveillance frequency among high-risk patients statistically significantly exceeded surveillance among low-risk patients at only 4 facilities. Across all facilities, surveillance frequencies for low- vs high-risk patients were moderately strongly correlated (r = 0.52; P < .001). CONCLUSIONS AND RELEVANCE Patients with early-stage bladder cancer undergo cystoscopic surveillance at comparable frequencies regardless of risk. This finding highlights the need to understand barriers to risk-aligned surveillance with the goal of making it easier for clinicians to deliver it in routine practice.

Abstract
Implementation science is a rapidly developing field dedicated to the scientific investigation of strategies to facilitate improvements in healthcare delivery. These strategies have been shown in several settings to lead to more complete and sustained change. In this essay, we discuss how refined surveillance recommendations for non-muscle-invasive bladder cancer, which involve a complex interplay between providers, healthcare facilities, and patients, could benefit from use of implementation strategies derived from the growing literature of implementation science. These surveillance recommendations are based on international consensus and indicate that the frequency of surveillance cystoscopy should be aligned with each patient's risk for recurrence and progression of disease. Risk-aligned surveillance entails cystoscopy at 3 and 12 months followed by annual surveillance for low-risk cancers, with surveillance every 3 months reserved for high-risk cancers. However, risk-aligned care is not the norm. Implementing risk-aligned surveillance could curtail overuse among low-risk patients, while curbing underuse among high-risk patients. Despite clear direction from respected and readily available clinical guidelines, there are multiple challenges to implementing risk-aligned surveillance in a busy clinical setting. Here, we describe how implementation science methods can be systematically used to understand determinants of care and to develop strategies to improve care. We discuss how the tailored implementation for chronic diseases framework can facilitate systematic assessment and how intervention mapping can be used to develop implementation strategies to improve care. Taken together, these implementation science methods can help facilitate practice transformation to improve risk-aligned surveillance for bladder cancer.

Abstract
INTRODUCTION Urinary biomarkers are being developed to detect bladder cancer recurrence/progression in patients with non-muscle-invasive bladder cancer (NMIBC). We conducted a questionnaire-based study to determine what diagnostic accuracy and cost would such test(s) need for both patients and urologic oncologists to comfortably forgo surveillance cystoscopy in favour of these tests. METHODS Surveys were administered to NMIBC patients at followup cystoscopy visit and to physician members of the Society of Urologic Oncology. Participants were questioned about acceptable false-negative (FN) rates and costs for such alternatives, in addition to demographics that could influence chosen error rates and costs. RESULTS A total of 137 patient and 51 urologic oncologist responses were obtained. Seventy-seven percent of patients were not comfortable with urinary biomarker(s) alternatives to repeat cystoscopy, with a further 14% willing to accept such alternatives only if the FN rate were 0.5% or lower. Seventy-five percent of urologic oncologists were comfortable with an alternative urinary biomarker test(s), with 37% and 33% willing to accept FN rates of 5% and 1%, respectively. Forty-seven percent of patients were not willing to pay out-of-pocket for such tests, while 61% of urologic oncologists felt that a price range of $100-500 would be reasonable. CONCLUSIONS This is the first survey evaluating patient and urologic oncologist perspectives on acceptable error rates and costs for urinary biomarker alternatives to surveillance cystoscopy for patients with NMIBC. Despite potential responder bias, this study suggests that urinary biomarker(s) will require sensitivity equivalent to that of cystoscopy in order to completely replace it in surveillance of patients with NMIBC.

Abstract
The population of adult cancer survivors is increasing over time and they are at risk of developing recurrent and secondary cancers, even years after completion of treatment. Post-treatment care of survivors is increasingly the responsibility of primary care providers. Surveillance for recurrence and screening for secondary malignancies related to treatment depend largely on the primary malignancy, treatment regimen, and presence of a hereditary cancer syndrome, such as a BRCA mutation. This article presents surveillance strategies for the most common malignancies.

Abstract
Bladder cancer is a common disease with a stable incidence for the past few decades despite advancements in molecular and genetic determinants of cancer development and progression. Cystoscopy remains the standard for detection and surveillance of bladder cancer, but it is an invasive and potentially costly procedure. With the knowledge of molecular alterations associated with bladder cancer numerous urine-based tumor markers have become commercially available. These urine markers have been evaluated in all clinical scenarios for the detection of bladder cancer including screening, hematuria, atypical cytology evaluation, and surveillance, but given the relative lack of impactful trials they are not routinely utilized. The efforts to develop markers with increased sensitivity to replace cystoscopy for the detection of bladder cancer have thus far been unsuccessful as well. This review addresses role of urine markers for screening, detection, and surveillance of bladder cancer.

Abstract
OBJECTIVES To evaluate the diagnostic accuracy of the Xpert Bladder Cancer (BC) Monitor, compared with cystoscopy and cytology in the oncological follow-up of non-muscle-invasive bladder cancer (NMIBC). MATERIAL AND METHODS A total of 140 patients with a history of NMIBC undergoing routine surveillance at our institution were enrolled prospectively in this study (ISRCTN study registry number 37210907). Urine cytology was evaluated according to the Paris classification system. In addition, urinary specimens were analysed using the Xpert BC Monitor, which measures five target mRNAs (ABL1, CRH, IGF2, UPK1B, ANXA10) using real-time PCR. Descriptive analysis, diagnostic accuracy including sensitivity, specificity, positive (PPV) and negative predictive value (NPV), receiver-operating characteristic curve, and area under the curve (AUC) were calculated. RESULTS The overall sensitivity (0.84) and NPV (0.93) of the Xpert BC Monitor were significantly superior to those of bladder washing cytology (0.33 and 0.76; P < 0.001). Subgroup analyses confirmed the high sensitivity of the Xpert BC Monitor even in low-grade (0.77) and pTa (0.82) disease compared with barbotage cytology (low-grade: 0.13; pTa: 0.21). The overall specificity of the Xpert BC Monitor and barbotage cytology was similar (0.91 vs 0.94; P = 0.41). Combining the Xpert BC Monitor with barbotage cytology (AUC = 0.85) did not enhance diagnostic performance compared with the performance of the Xpert BC Monitor alone (AUC = 0.87). CONCLUSION In this study, we report for the first time that the Xpert BC Monitor, a new mRNA-based urine test, outperforms cytology with regard to sensitivity and NPV, even in low-grade and pTa tumours, with no reduction of specificity.
