Abstract
OBJECTIVE Information on bladder cancer (BC) according to the risk scoring for recurrence or progression in a general population is scarce despite its clinical relevance. The objective was to describe the characteristics of incident BC in a general population, with a focus on the initial management of high-risk non-muscle invasive BC (HR-NMIBC). MATERIALS BC incident in 2011-2012 recorded in a population-based cancer registry were studied. Data was extracted from medical files. NMIBC were classified according to potential risk for recurrence/progression. Individual and tumor characteristics of incident BC were described. Incidence, initial management and survival (12/31/2021) of HR-NMIBC were assessed. RESULTS Among 538 BC cases, 380 were NMIBC [119 low (22.1%), 163 intermediate (30.3%), 98 high (18.2%) risk] and 147 (27.3%) were MIBC. HR-NMIBC diagnostic and therapeutic management [imaging, re-TUR, multidisciplinary team meetings (MDT) assessment, specific treatment] revealed discrepancies with guidelines recommendations. Seventy-two out of 98 cases were assessed in an MDT with a median time from diagnosis of 18days [first quartile: 12-third quartile: 32]. Globally, treatment agreed with MDT decisions. Intravesical instillation was the most common treatment (n=56) but 27 HR-NMIBC did not receive specific treatment after TUR. Five and 10years overall survival was 52% [42-63] and 41% [31-51], respectively. Five years net survival was 63% [47-75]. CONCLUSIONS Despite National cancer plans aiming to improve care giving and despite the severity of HR-NMIBC, guideline-recommended patterns of care were underused in this region. This may deserve attention to identify obstacles to guideline adoption to try to improve BC patient care and survival. LEVEL OF EVIDENCE: 3

THE FRENCH JOURNAL OF UROLOGY 2024; 34:102705. [PMID: 39059766 DOI: 10.1016/j.fjurol.2024.102705] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/10/2024] [Revised: 07/17/2024] [Accepted: 07/18/2024] [Indexed: 07/28/2024]
Abstract
PURPOSE Non-muscle invasive bladder cancers (NMIBC) constitute approximately 75% of bladder cancer cases. Primary transurethral resection (TUR) plays a pivotal role in both diagnosis and treatment. However, despite initial resection, tumors are often missed, leaving behind microscopic residual tumors. This study aims to prospectively investigate the surgical margins of tumors, which may serve as a potential source of residual tumors. MATERIALS AND METHODS Seventy patients diagnosed with NMIBC who underwent primary TUR were enrolled in this study. Following initial resection, samples were collected from the normal-appearing mucosa extending 1cm beyond the surgical margins. Lesions were categorized as 'healthy margins' for benign lesions, 'tumoral margins' for urothelial cancer, and 'dysplastic margins' for urothelial dysplasia. Clinical and pathological features of these groups were compared, and risk factors for detecting transitional cell carcinoma (TCC) in the normal-looking mucosa were analyzed. RESULTS The tumoral margins group showed a significantly higher rate of T1 stage tumors compared to the healthy margins group, and a significantly higher rate of high-grade (HG) tumors compared to the dysplastic margins group. Moreover, the tumoral margins group had a significantly higher proportion of high-risk patients (85.7%) compared to the other groups, while the healthy margins group had a significantly higher proportion of low-risk patients (35.3%) compared to the tumoral margins group (0.0%). Additionally, the tumoral margins group demonstrated a significantly higher rate of carcinoma in situ (CIS) compared to the healthy margins group (35.7% vs. 5.9%). Detection of urothelial cancer at the margins was associated with T1 stage, HG stage, and the presence of CIS based on univariate analyses. CONCLUSION To minimize residual tumors and prevent recurrence in patients undergoing primary TUR, we advocate for the resection of macroscopically visible tumors with nearly 2cm of intact bladder tissue, thereby enhancing the quality of TUR. LEVEL OF EVIDENCE This study provides Level II evidence, based on its design as a prospective observational study. The findings are derived from well-designed cohort analyses, providing significant associations and insights into the factors affecting surgical margins in NMIBC patients.

Abstract
Tumor cells can survive when detached from the extracellular matrix (ECM) or lose cell-cell connections, a phenomenon known as anoikis-resistance (AR). AR is closely associated with tumor cell metastasis and recurrence, enabling tumor cells to disseminate, migrate, and invade after detachment. To address this issue, a novel intervention method combining intraoperative hemostasis with multifunctional nanozyme driven-enhanced chemodynamic therapy (ECDT) has been proposed, which holds the potential to weaken the AR capability of tumor cells and suppress tumor recurrence. Here, a nanocomposite containing a dendritic mesoporous nanoframework with Cu2+ was developed using an anion-assisted approach after surface PEG grafting and glucose oxidase (GOx) anchoring (DMSN-Cu@GOx/PEG). DMSN-Cu@GOx/PEG was further encapsulated in a thermal-sensitive hydrogel (H@DMSN-Cu@GOx/PEG). DMSN-Cu@GOx/PEG utilizes its high peroxidase (POD) activity to elevate intracellular ROS levels, thereby weakening the AR capability of bladder cancer cells. Additionally, through its excellent catalase (CAT) activity, DMSN-Cu@GOx/PEG converts the high level of hydrogen peroxide (H2O2) catalyzed by intracellular GOx into oxygen (O2), effectively alleviating tumor hypoxia, downregulating hypoxia-inducible factor-1α (HIF-1α) expression, inhibiting epithelial-mesenchymal transition (EMT) processes, and ultimately suppressing the migration and invasion of bladder cancer cells. Interestingly, in vivo results showed that the thermosensitive hydrogel H@DMSN-Cu@GOx/PEG could rapidly gel at body temperature, forming a gel film on wounds to eliminate residual tumor tissue after tumor resection surgery. Importantly, H@DMSN-Cu@GOx/PEG exhibited excellent hemostatic capabilities, effectively enhancing tissue coagulation during post-tumor resection surgery and mitigating the risk of cancer cell dissemination and recurrence due to surgical bleeding. Such hydrogels undoubtedly possess strong surgical application. Our developed novel nanosystem and hydrogel can inhibit the AR capability of tumor cells and prevent recurrence post-surgery. This study represents the first report of using dendritic mesoporous silica-based nanoreactors for inhibiting the AR capability of bladder cancer cells and suppressing tumor recurrence post-surgery, providing a new avenue for developing strategies to impede tumor recurrence after surgery.

Transurethral En Bloc Resection Versus Standard Resection of Bladder Tumour: A Randomised, Multicentre, Phase 3 Trial. Eur Urol 2024; 86:103-111. [PMID: 38692956 DOI: 10.1016/j.eururo.2024.04.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2024] [Revised: 03/25/2024] [Accepted: 04/10/2024] [Indexed: 05/03/2024]
Abstract
BACKGROUND AND OBJECTIVE Conventionally, standard resection (SR) is performed by resecting the bladder tumour in a piecemeal manner. En bloc resection of the bladder tumour (ERBT) has been proposed as an alternative technique in treating non-muscle-invasive bladder cancer (NMIBC). The objective of this study is to investigate whether ERBT could improve the 1-yr recurrence rate of NMIBC, as compared with SR. METHODS A multicentre, randomised, phase 3 trial was conducted in Hong Kong. Adults with bladder tumour(s) of ≤ 3cm were enrolled from April 2017 to December 2020, and followed up until 1 yr after surgery. Patients were randomly assigned to receive either ERBT or SR in a 1:1 ratio. The primary outcome was 1-yr recurrence rate. A modified intention-to-treat analysis on patients with histologically confirmed NMIBC was performed. The main secondary outcomes included detrusor muscle sampling rate, operative time, hospital stay, 30-d complications, any residual or upstaging of disease upon second-look transurethral resection, and 1-yr progression rate. KEY FINDINGS AND LIMITATIONS A total of 350 patients underwent randomisation, and 276 patients were histologically confirmed to have NMIBC. At 1 yr, 31 patients in the ERBT group and 46 in the SR group developed recurrence; the Kaplan-Meier estimate of 1- yr recurrence rates were 29% (95% confidence interval, 18-37) in the ERBT group and 38% (95% confidence interval, 28-46) in the SR group (p = 0.007). Upon a subgroup analysis, patients with 1-3 cm tumour, single tumour, Ta disease, or intermediate-risk NMIBC had a significant benefit from ERBT. None of the patients in the ERBT group and three patients in the SR group developed progression to muscle-invasive bladder cancer; the Kaplan-Meier estimates of 1-yr progression rates were 0% in the ERBT group and 2.6% (95% confidence interval, 0-5.5) in the SR group (p = 0.065). The median operative time was 28 min (interquartile range, 20-45) in the ERBT group and 22 min (interquartile range, 15-30) in the SR group (p < 0.001). All other secondary outcomes were similar in the two groups. CONCLUSIONS AND CLINICAL IMPLICATIONS In patients with NMIBC of ≤ 3cm, ERBT resulted in a significant reduction in the 1-yr recurrence rate when compared with SR. The study results support ERBT as the first-line surgical treatment for patients with bladder tumours of≤ 3cm.

Abstract
Diagnostic cystoscopy in combination with transurethral resection of the bladder tumour are the standard for the diagnosis, surgical treatment and surveillance of bladder cancer. The ability to inspect the bladder in its current form stems from a long chain of advances in imaging science and endoscopy. Despite these advances, bladder cancer recurrence and progression rates remain high after endoscopic resection. This stagnation is a result of the heterogeneity of cancer biology as well as limitations in surgical techniques and tools, as incomplete resection and provider-specific differences affect cancer persistence and early recurrence. An unmet clinical need remains for solutions that can improve tumour delineation and resection. Translational advances in enhanced cystoscopy technologies and artificial intelligence offer promising avenues to overcoming the progress plateau.

Abstract
Introduction Bladder cancer (BCa) is characterised by high prevalence, multifocality, and frequent recurrence, imposing significant clinical and economic burdens. Accurate staging, particularly distinguishing non-muscle-invasive bladder cancer (NMIBC) from muscle-invasive bladder cancer (MIBC) disease, is crucial for guiding treatment decisions. This narrative review explores the potential implications of incorporating multiparametric magnetic resonance imaging (mpMRI) and the Vesical Imaging Reporting Data System (VI-RADS) into BCa staging, focusing on repeat transurethral resection of bladder tumour (re-TURBT). Methods A comprehensive search of PubMed, EMBASE, and MEDLINE databases identified studies published from 2018 to 2023 discussing mpMRI or VI-RADS in the context of re-TURBT for BCa staging. Studies meeting inclusion criteria underwent qualitative analysis. Results Six recent studies met inclusion criteria. VI-RADS scoring, accurately predicted muscle invasion, aiding in NMIBC/MIBC differentiation. VI-RADS scores of ≥3 indicated MIBC with high sensitivity and specificity. VI-RADS potentially identified patients benefiting from re-TURBT and those for whom it could be safely omitted. Discussion mpMRI and VI-RADS offer promising prospects for BCa staging, potentially correlating more closely with re-TURBT and radical cystectomy histopathology than initial TURBT. However, validation and careful evaluation of clinical integration are needed. Future research should refine patient selection and optimise mpMRI's role in BCa management. Conclusion VI-RADS scoring could revolutionise BCa staging, especially regarding re-TURBT. There is potential that VI-RADS correlates more with the histopathology of re-TURBT and radical cystectomy than initial TURBT. While promising, ongoing research is essential to validate utility, refine selection criteria, and address economic considerations. Integration of VI-RADS into BCa staging holds potential benefits for patients and health care systems.

Abstract
INTRODUCTION AND OBJECTIVES Transurethral resection of bladder tumor (TURBT) is crucial in the treatment of bladder tumors and when incorrectly performed can cause staging mistakes. To avoid these errors, a second resection is recommended in selected cases. The aim of this study is to evaluate the surgeon's ability to predict histologically complete primary resection of newly diagnosed bladder tumors avoiding the need for a second TURBT. METHODS This is a prospective, observational study involving 47 consecutive patients with newly diagnosed bladder tumors who had previously undergone primary TURBT, and met EAU criteria for second-look TURBT. Second-look TURBT specimens were analyzed for routine histological assessment and compared with the surgeon's impression of the tumor at initial resection. RESULTS Of 91 patients submitted to primary TURBT, 47 met the criteria for second-look TURBT. Second-look specimens revealed residual disease in 20.9% of patients and 3 (6.4%) of patients showed upstaging disease. The sensitivity of a senior to detect disease on second-look TURBT in relation to muscle invasion was 75%, and the specificity was 85%. CONCLUSIONS Second-look TURBT is crucial in the treatment of bladder cancer and cannot be replaced by a surgeon's opinion, so international recommendations should be followed. Supervision of less experienced surgeons is a cornerstone.

Methods We retrospectively analyzed the clinical data of patients with malignant bladder tumors treated at the First Affiliated Hospital of Soochow University from January 2016 to December 2017 and compared the differences in 1-year, 2-year, 3-year, 5-year, and comprehensive overall survival (OS) and progression-free survival (PFS) between BCG instillation treatment and RC treatment. Survival curves were drawn to show differences in OS and PFS between the two groups. Concurrently, univariate and multivariate COX analyses were performed to identify risk factors affecting OS and PFS, and a nomogram was created. Results In total, 146 patients were included in the study, of whom 97 and 49 were in the BCG and RC groups, respectively. No statistical differences were observed in the 1- and 2-year OS and PFS between the two groups, whereas significant statistical differences were found in the 3-year, 5-year, and comprehensive OS and PFS. Survival curves also confirmed the statistical differences in OS and PFS between the BCG and RC groups. Multivariate COX analysis revealed that the treatment method, concomitant satellite lesions, and albumin-to-alkaline phosphatase ratio (AAPR) were independent risk factors affecting OS and PFS. The nomogram that was further plotted showed good predictive ability for OS and PFS. Conclusion For patients who exhibit high-level T1 pathology after both initial and repeat TURBT, especially those with low AAPR, and concomitant satellite lesions, choosing RC as a treatment method offers a better prognosis.

Abstract
Bladder cancer (BC) is a common genitourinary malignancy that exhibits silent morbidity and high mortality rates because of a lack of diagnostic markers and limited effective treatments. Here, we evaluated the role of the lncRNA brain cytoplasmic RNA 1 (BCYRN1) in BC. We performed loss-of-function assays to examine the effects of BCYRN1 downregulation in T24 and BOY BC cells. We found that BCYRN1 downregulation significantly inhibited the proliferation, migration, invasion, and three-dimensional spheroid formation ability and induced apoptosis in BC cells. Additionally, gene set enrichment analysis (GSEA) using RNA sequences from tumor fractions showed that BCYRN1 downregulation decreased the expression of mRNAs associated with the cell cycle. These findings were supported by observations of G2/M arrest in flow cytometry assays. Finally, we examined the expression of serum exosomal BCYRN1 as a biomarker. Clinically, BCYRN1 expression in serum exosomes from patients with BC (n = 31) was significantly higher than that in healthy donors (n = 19; mean difference: 4.1-fold higher, p < 0.01). Moreover, in patients who had undergone complete resection of BC, serum exosomal BCYRN1 levels were significantly decreased (n = 8). Thus, serum exosomal BCYRN1 may be a promising diagnostic marker and therapeutic target in patients with BC.

Abstract
PURPOSE To investigate the influence of deep learning reconstruction (DLR) on bladder MRI, specifically examination time, image quality, and diagnostic performance of vesical imaging reporting and data system (VI-RADS) within a prospective clinical cohort. METHODS Seventy participants with bladder cancer who underwent MRI between August 2022 and February 2023 with a protocol containing standard T2-weighted imaging (T2WIS), standard diffusion-weighted imaging (DWIS), fast T2WI with DLR (T2WIDL), and fast DWI with DLR (DWIDL) were enrolled in this prospective study. Imaging quality was evaluated by measuring signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), and qualitative image quality scoring. Additionally, the apparent diffusion coefficient (ADC) of bladder lesions derived from DWIS and DWIDL was measured and VI-RADS scoring was performed. Paired t-test or paired Wilcoxon signed-rank test were performed to compare image quality score, SNR, CNR, and ADC between standard sequences and fast sequences with DLR. The diagnostic performance for VI-RADS was assessed using the area under the receiver operating characteristic curve (AUC). RESULTS Compared to T2WIS and DWIS, T2WIDL and DWIDL reduced the acquisition time from 5:57 min to 3:13 min and showed significantly higher SNR, CNR, qualitative image quality score of overall image quality, image sharpness, and lesion conspicuity. There were no significant differences in ADC and AUC of VI-RADS between standard sequences and fast sequences with DLR. CONCLUSIONS The application of DLR to T2WI and DWI reduced examination time and significantly improved image quality, maintaining ADC and the diagnostic performance of VI-RADS for evaluating muscle invasion in bladder cancer.

Repeat Transurethral Resection for Non-muscle-invasive Bladder Cancer: An Updated Systematic Review and Meta-analysis in the Contemporary Era. Eur Urol Focus 2024; 10:41-56. [PMID: 37495458 DOI: 10.1016/j.euf.2023.07.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Revised: 06/04/2023] [Accepted: 07/13/2023] [Indexed: 07/28/2023]
Abstract
CONTEXT Repeat transurethral resection (reTUR) is a guideline-recommended treatment strategy in high-risk non-muscle-invasive bladder cancer (NMIBC) patients treated with transurethral resection of bladder tumor (TURBT); however, the impact of recent procedural/technological developments on reTUR outcomes has not been assessed yet. OBJECTIVE To assess the outcomes of reTUR for NMIBC in the contemporary era, focusing on whether temporal differences and technical advancement, specifically, photodynamic diagnosis and en bloc resection of bladder tumor (ERBT), affect the outcomes. EVIDENCE ACQUISITION Multiple databases were queried in February 2023 for studies investigating reTUR outcomes, such as residual tumor and/or upstaging rates, its predictive factors, and oncologic outcomes, including recurrence-free (RFS), progression-free (PFS), cancer-specific (CSS), and overall (OS) survival. We synthesized comparative outcomes adjusting for the effect of possible confounders. EVIDENCE SYNTHESIS Overall, 81 studies were eligible for the meta-analysis. In T1 patients initially treated with conventional TURBT (cTURBT) in the 2010s, the pooled rates of any residual tumors and upstaging on reTUR were 31.4% (95% confidence interval [CI]: 26.0-37.2%) and 2.8% (95% CI: 2.0-3.8%), respectively. Despite a potential publication bias, these rates were significantly lower than those in patients treated in the 1990-2000s (both p < 0.001). ERBT and visual enhancement-guided cTURBT significantly improved any residual tumor rates on reTUR compared with cTURBT based on both matched-cohort and multivariable analyses. Among studies adjusting for the effect of possible confounders, patients who underwent reTUR had better RFS (hazard ratio [HR]: 0.78, 95% CI: 0.62-0.97) and OS (HR: 0.86, 95% CI: 0.81-0.93) than those who did not, while it did not lead to superior PFS (HR: 0.74, 95% CI: 0.47-1.15) and CSS (HR: 0.94, 95% CI: 0.86-1.03). CONCLUSIONS reTUR is currently recommended for high-risk NMIBC based on the persistent high rates of residual tumors after primary resection. Improvement of resection quality based on checklist applications and recent technical/procedural advancements hold the promise to omit reTUR. PATIENT SUMMARY Recent endoscopic/procedural developments improve the outcomes of repeat resection for high-risk non-muscle-invasive bladder cancer. Further investigations are urgently needed to clarify the potential impact of the use of these techniques on the need for repeat transurethral resection in the contemporary era.

Adv Radiat Oncol 2024; 9:101302. [PMID: 38260237 PMCID: PMC10801638 DOI: 10.1016/j.adro.2023.101302] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Accepted: 03/26/2023] [Indexed: 01/24/2024] Open
Abstract
Purpose The aim of this study was to determine whether escalating the local radiation dose can improve the outcome of residual bladder cancer after transurethral resection of bladder tumor without increasing treatment-related toxicity. Methods and Materials The treatment plans and medical records of patients with bladder cancer treated with curative-intent radiation therapy between 2008 and 2020 were reviewed. Those who had residual tumors in the computed tomography simulation images were included. A cumulative radiation dose higher than 6600 cGy was defined as dose escalation. The effect of dose escalation on 3-year locoregional control, progression-free survival, and overall survival was evaluated. Results A total of 149 patients with residual tumors were identified. The median follow-up period was 27.5 months. Among them, 51 patients received an escalated radiation dose, and 98 received a standard dose in the residual tumor area. Patients in the dose-escalation group had higher 3-year locoregional control (65.6% vs 27.8%; P < .001) and progression-free survival (42.6% vs 18.2%; P < .001) than the standard-dose group. Overall survival also showed a trend favoring the dose-escalation group (54.9% vs 36.2%; P = .059). In the multivariate analyses, the differences between the dose-escalation and standard-dose groups were significant in terms of locoregional control (hazard ratio, 0.32; CI, 0.18-0.59; P = <.001) and progression-free survival (hazard ratio, 0.51; CI, 0.32-0.82; P = .005). There was no statistical difference in acute and chronic treatment-related toxicities between the 2 groups. Conclusions The outcome of residual bladder cancer after transurethral resection of bladder tumor could be improved by dose-escalated radiation therapy.

Management of high-grade papillary Ta or T1 bladder cancer after restaging transurethral resection: A retrospective study comparing Bacillus Calmette-Guerin therapy upfront versus a third resection. THE FRENCH JOURNAL OF UROLOGY 2024; 34:102548.

Abstract
PURPOSE Performing restaging transurethral bladder resection (reTURB) for high-risk non-muscle invasive bladder cancer (NMIBC) reduces the risk of recurrence and tumour understaging. Management of residual high-grade papillary Ta or T1 after reTURB has changed this last 10years in international recommendations. This study aimed to compare the recurrence free survival according to the different management procedures performed. MATERIALS AND METHODS Patients who underwent reTURB for initial high-risk NMIBC between 2011 and 2020 were included. Patients with residual high-grade papillary Ta or T1 tumour after reTURB were divided into two groups: BCG instillations upfront versus BCG following a third-look resection (3TURB). Patient and tumour characteristics, BCG instillations, recurrence-free survival were retrospectively analysed. RESULTS A total of 162 high-risk patients were included. Sixty-one (37.7%) had residual high-grade papillary Ta or T1 at reTURB: 35 (21.6%) had BCG instillations upfront, 18 (11.2%) had a 3TURB and 8 (5%) had other management. The mean follow-up was 34.2weeks±20.2. Recurrence-free survival was significantly better in patients who underwent BCG instillations upfront (P<0.0043). Recurrence after BCG therapy following reTURB was significantly lower in patients with no residual NMIBC at 6 (92.5% vs. 72.4%, P<0.004) and 12months (85% vs. 67.3%, P<0.03). CONCLUSIONS The efficacy of intravesical BCG is compromised in case of residual tumour following TURB. The role of a 3TURB following a positive reTURB is not yet determined. This study has confirmed that residual tumor following reTURB is a negative predictive factor but could not demonstrate the value of a 3TURB compared to upfront BCG. LEVEL OF EVIDENCE: 3

Significance of Normalized Apparent Diffusion Coefficient in the Vesical Imaging-Reporting and Data System for Diagnosing Muscle-Invasive Bladder Cancer. J Magn Reson Imaging 2023. [PMID: 38153874 DOI: 10.1002/jmri.29208] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Revised: 12/16/2023] [Accepted: 12/18/2023] [Indexed: 12/30/2023] Open
Abstract
BACKGROUND Vesical Imaging-Reporting and Data System (VI-RADS) has been developed for assessing bladder cancer from multiparametric (mp) MRI but its performance in diagnosing muscle-invasive bladder cancer (MIBC) is suboptimal. PURPOSE To investigate associations between normalized apparent diffusion coefficient (NADC) and clinicopathological characteristics and to determine whether the inclusion of NADC can improve the performance of VI-RADS in diagnosing MIBC. STUDY TYPE Retrospective. POPULATION Two hundred seventy-five patients with pathologically confirmed bladder cancer (101 MIBC and 174 non-MIBC [NMIBC]) underwent preoperative mpMRI (233 male, 42 female). FIELD STRENGTH/SEQUENCE 3-T, T2-weighted imaging (turbo spin-echo), diffusion-weighted imaging (free-breathing spin-echo), and dynamic contrast-enhanced imaging (gradient-echo). ASSESSMENT NADC was the mean ADC of tumor divided by that of the iliopsoas muscles in trans caput femoris plane. Associations between NADC and clinicopathological characteristics were evaluated. Models were established for differentiating MIBC and NMIBC: VI-RADS model; VN model (VI-RADS and NADC), Images model (significant variables from imaging associated with MIBC), LN model (Images model without NADC), and Full model (all significant variables associated with MIBC). STATISTICAL TESTS Variables for model development were based on logistic regression. Models were evaluated by receiver operating characteristic (ROC) curve. Comparison of the area under the curves (AUCs) for the models used DeLong's test. A P value <0.05 was considered statistically significant. RESULTS NADC was significantly lower in lesions with diameter ≥ 3 cm, MIBC, histological high grade, lymph node metastasis, and lymphovascular invasion. Compared with VI-RADS model, the AUCs for VN model (VI-RADS score and NADC), Images model (VI-RADS score, NADC and tumor size) and Full model (VI-RADS score, NADC, tumor size and histological grade) were significantly higher. No significant differences were observed between the AUCs for VN model and Images model (P = 0.051). DATA CONCLUSION NADC reflects information about the aggressiveness of bladder cancer. Combining VI-RADS with NADC can improve performance in diagnosing MIBC. EVIDENCE LEVEL 4 TECHNICAL EFFICACY: Stage 2.

Abstract
Bladder cancer is a global health issue with sex differences in incidence and prognosis. Bladder cancer has distinct molecular subtypes with multiple pathogenic pathways depending on whether the disease is non-muscle invasive or muscle invasive. The mutational burden is higher in muscle-invasive than in non-muscle-invasive disease. Commonly mutated genes include TERT, FGFR3, TP53, PIK3CA, STAG2 and genes involved in chromatin modification. Subtyping of both forms of bladder cancer is likely to change considerably with the advent of single-cell analysis methods. Early detection signifies a better disease prognosis; thus, minimally invasive diagnostic options are needed to improve patient outcomes. Urine-based tests are available for disease diagnosis and surveillance, and analysis of blood-based cell-free DNA is a promising tool for the detection of minimal residual disease and metastatic relapse. Transurethral resection is the cornerstone treatment for non-muscle-invasive bladder cancer and intravesical therapy can further improve oncological outcomes. For muscle-invasive bladder cancer, radical cystectomy with neoadjuvant chemotherapy is the standard of care with evidence supporting trimodality therapy. Immune-checkpoint inhibitors have demonstrated benefit in non-muscle-invasive, muscle-invasive and metastatic bladder cancer. Effective management requires a multidisciplinary approach that considers patient characteristics and molecular disease characteristics.

Abstract
To determine whether Xpert bladder cancer monitor, a noninvasive PCR-based biomarker test, can predict the need for 2nd transurethral resection of the bladder (TURB) better than clinical assessment. Patients scheduled for TURB were prospectively screened. After initial TURB, patients were assigned to 2nd TURB or follow-up cystoscopy at 3 months (FU) by clinicians' discretion. Central urine cytology and Xpert monitor tests were performed prior to the 1st TURB and 2nd TURB or FU, respectively. Statistical analysis to compare clinical assessment and Xpert monitor comprised sensitivity (SENS), specificity (SPEC), NPV and PPV. Of 756 screened patients, 171 were included (114 with 2nd TURB, 57 with FU). Residual tumors were detected in 34 patients who underwent 2nd TURB, and recurrent tumors were detected in 2 patients with FU. SENS and SPEC of Xpert monitor were 83.3% and 53.0%, respectively, PPV was 32.6% and NPV was 92.1%. Clinical risk assessment outperformed Xpert monitor. In patients with pTa disease at initial TURB, Xpert monitor revealed a NPV of 96%. Xpert monitor was not superior than clinical assessment in predicting the need for 2nd TURB. It might be an option to omit 2nd TURB for selected patients with pTa disease.

Abstract
BACKGROUND Urothelial carcinoma is a major subtype of bladder cancer and small cell carcinoma (SCC) is a rare type of cancer in clinical practice. Pathologic collision of urinary bladder urothelial carcinoma with SCC is not common in clinical settings. CASE PRESENTATION Here, we report a patient with high-grade papillary carcinoma which changed to collision tumor with SCC. The patient underwent radical cystectomy; however, neck and mediastinum lymph nodes metastases were detected 11 months after the operation. The lymph nodes were diagnosed pathologically as SCC. Chemoradiotherapy was subsequently prescribed. Unfortunately, this patient died of COVID-19 in early 2023. DISCUSSION We hypothesized the mechanism underlying this pathological transformation. For patients with urothelial bladder cancer, pathological analysis should be conducted to allow standardized and persistent treatment. Moreover, drugs should be selected depending on the type of pathology, especially for patients who develop relapse, since collision tumor or other pathological tumors may be present. CONCLUSIONS We recommend that radical cystectomy be performed early enough for patients with non-muscle invasive bladder cancer, who are at a high risk of tumor recurrence. However, this conclusion needs to be validated in a larger number of patients.

Abstract
BACKGROUND Intravesical Bacille Calmette-Guerin (BCG) therapy has been reported to be effective in preventing recurrence and progression in non-muscle invasive bladder cancer. Furthermore, photodynamic diagnosis (PDD)-assisted transurethral resection of bladder tumor (TURBT) improves the accuracy of cancer diagnosis and contributes to lower recurrence rates. The purpose of this study is to investigate whether more tumor resection with PDD-TURBT rather than conventional TURBT before BCG therapy outweighs the benefit of BCG therapy alone. METHODS Patients who underwent intravesical BCG therapy following TURBT in our institution from 2010 to 2021 were included. They were divided into the following two groups: those who received PDD-TURBT before BCG treatment (PDD + BCG group) and those who received conventional TURBT before BCG treatment (WL + BCG group). The 2-year recurrence-free survival (RFS) and progression-free survival (PFS) of the two groups were retrospectively analyzed and compared. RESULTS The 2-year RFS was significantly improved in the PDD + BCG group (hazard ratio [HR]: 2.41, 95% confidence interval [CI]: 1.26-4.60; p = 0.025). No significant difference in 2-year PFS was noted between the two groups. Analysis of prognostic factors for RFS showed that PDD-TURBT w We think that this text does not adequately express the meaning that we want to deliver to the reader.as a significant prognostic factor in univariate analysis (HR: 0.41, 95% CI: 0.18-0.92; p = 0.03). CONCLUSION BCG treatment following PDD-TURBT significantly improved RFS more than BCG therapy following WL-TURBT. More accurate tumor localization and more efficient tumor resection by PDD-TURBT may have a positive impact on subsequent BCG treatments even if the treatment is administered postoperatively.

Abstract
INTRODUCTION Restaging transurethral resection (re-TUR) of high grade T1 bladder cancer (HGT1-BC) is recommended but the impact in terms of recurrence-free survival (RFS) and progression-free survival (PFS) is discussed. The objective of this study was to evaluate our practice of re-TUR for these tumors and its impact on overall survival (OS), RFS and PFS. MATERIALS AND METHODS A retrospective observational study was conducted between 2010 and 2020. The inclusion criteria was the presence of newly diagnosed HGT1-BC. Patients with incomplete resection, suspicion of infiltrating tumor, upper tract urothelial cancer, or metastatic disease were ineligible. Two groups were defined : Group 1 with re-TUR and Group 2 without re-TUR. RFS and PFS were evaluated. RESULTS A total of 78 patients were included, including 50 (64,1%) in group 1. There were no significant differences between the two groups. The mean time to re-TUR was 8 weeks and 60% residual tumor was found. Initial under-staging was found in 12% of cases. RFS and PFS were significantly better in Group 1 (P=0.0019; P=0,02). No significant were found between the groups in OS and specific survival (SS). CONCLUSION Performing a re-TUR for high grade T1 bladder tumors allows detection of residual tumor and decreases the risk of under-evaluation. It is associated with a significant improvement in RFS and PFS with no impact on OS and SS. LEVEL OF EVIDENCE: 4

Abstract
OBJECTIVES To assess the clinical significance of repeat transurethral resection (reTUR) and surgical margin status after en bloc resection of bladder tumour (ERBT) for pathological T1 (pT1) bladder cancer. PATIENTS AND METHODS We retrospectively analysed the record of 106 patients with pT1 high-grade bladder cancer who underwent ERBT between April 2013 and February 2021 at multiple institutions. All specimens were reviewed by a genitourinary pathologist. The primary outcome measures were recurrence-free survival (RFS) and progression-free survival (PFS) between patients with and those without reTUR. We also analysed the predictive value of surgical margin on the likelihood of residual tumour on reTUR. RESULTS A reTUR was performed in 50 of the 106 patients. The 2-year RFS and 3-year PFS were comparable between patients who underwent reTUR and those who did not (55.1% vs 59.9%, P = 0.6, 80.6% vs 82.6%, P = 0.6, respectively). No patient was upstaged to pT2 on reTUR. Regarding the surgical margin status, there were no recurrences at the original site in 51 patients with negative horizontal margins. Cox proportional hazard analysis revealed that a positive vertical margin was an independent prognostic factor of worse PFS. On reTUR, six pTa/is residues were detected in patients with a positive horizontal margin, and three pT1 residues were detected in one patient with a positive vertical margin or other adverse pathological features. CONCLUSIONS A reTUR after ERBT for pT1 bladder cancer appears not to improve either recurrence or progression. Surgical margin status affects prognosis and reTUR outcomes. A reTUR can be omitted after ERBT in patients with pT1 bladder cancer and negative margins; for those with positive horizontal or vertical margins, reTUR should remain the standard until proven otherwise.

Is a restaging TURBT necessary in high-risk NMIBC if the initial TURBT was performed with blue light? Urol Oncol 2023; 41:109.e9-109.e14.

Abstract
OBJECTIVES To evaluate whether a restaging transurethral resection of bladder tumor (TURBT) is necessary in high-risk nonmuscle invasive bladder cancer (NMIBC) if the initial TURBT was performed using blue light (BL) technology. METHODS AND MATERIALS Using the multi-institutional Cysview registry between 2014 and 2021, all consecutive adult patients with known NMIBC (Ta and T1 disease) who underwent TURBT followed by a restaging TURBT within 8 weeks were reviewed. Patients were stratified according to their initial TURBT, BL vs. white light (WL), and compared to determine rates of residual disease and upstaging. Univariate analysis was performed using Mann-Whitney U and chi-square tests, with P < 0.05 considered significant. RESULTS Overall, 115 patients had TURBT for NMIBC followed by a restaging TURBT within 8 weeks and were included in the analysis. Patients who underwent BL compared to WL for their initial TURBT had higher rates of benign pathology on restaging TURBT, although this was not statistically significant (47% vs. 30%; P = 0.08). Of patients with residual tumors on restaging TURBT, there were no differences in rates of Ta (22% vs. 26.5%; P = 0.62), T1 (22% vs. 26.5%; P = 0.62), or CIS (5.5% vs. 13%; P = 0.49) when the initial TURBT was done using BL compared to WL. Rates of upstaging to muscle invasive disease were also not different when initial TURBT was performed using BL compared to WL (3% vs. 4%; P = 0.78). CONCLUSIONS TURBT using BL does not reduce rates of residual disease or risk of upstaging on restaging TURBT in Ta or T1 disease. Thus, a restaging TURBT is still necessary even if initial TURBT was performed using BL.

Abstract
PURPOSE To evaluate the efficacy of repeat transurethral resection on restaging, preventing tumor recurrence and progression in high-risk non-muscle invasive bladder cancer patients who received initial en bloc resection. METHODS AND PATIENTS We reviewed retrospectively the clinical records of 330 consecutive patients who received en bloc resection for non-muscle invasive bladder cancer. Eligible patients with and without repeat transurethral resection were matched 1:1 by propensity score. Important covariates were balanced between the two groups. We compared the recurrence-free survival, progression-free survival, recurrence rate, and progression rate between groups. And the perioperative results regarding residual tumors and the safety of the repeat resection were also evaluated. RESULTS Finally, there are 245 patients included in our analysis with a median follow-up duration of 19 months (range 3-50). Detrusor muscle presented in 244 (99.6%) specimens at initial en bloc resection. And among them, 30 (12.2%) patients had undergone a repeat resection and 215 (87.8%) did not. After 1:1 propensity score matching, 30 pairs were further analyzed.No case of upstaging was identified in repeat resection. During the follow-up, recurrence was observed in 5 (16.7%) and 7 (23.3%) patients in reresection group and non-reresection group, respectively. And progression was found only in 1 (3.3%) patient in each group. The 1-year recurrence-free survival estimates were comparable (86.7% vs 83.3%, p = 0.86) between groups. CONCLUSION Our study demonstrates that repeat resection after initial transurethral en bloc resection for bladder tumor appears not to improve staging accuracy, recurrence, and progression.

Abstract
Bladder cancer (BLCA) is one of the most common malignant tumors of the urinary system, but the current therapeutic strategy based on chemotherapy and immune checkpoint inhibitor (ICI) therapy cannot meet the treatment needs, mainly owing to the endogenous or acquired apoptotic resistance of cancer cells. Targeting necroptosis provides a novel strategy for chemotherapy and targeted drugs and improves the efficacy of ICIs because of strong immunogenicity of necroptosis. Therefore, we systemically analyzed the necroptosis landscape on therapy and prognosis in BLCA. We first divided BLCA patients from The Cancer Genome Atlas (TCGA) database into two necroptosis-related clusters (C1 and C2). Necroptosis C2 showed a significantly better prognosis than C1, and the differential genes of C2 and C1 were mainly related to the immune response according to GO and KEGG analyses. Next, we constructed a novel necroptosis-related gene (NRG) signature consisting of SIRT6, FASN, GNLY, FNDC4, SRC, ANXA1, AIM2, and IKBKB to predict the survival of TCGA-BLCA cohort, and the accuracy of the NRG score was also verified by external datasets. In addition, a nomogram combining NRG score and several clinicopathological features was established to more accurately and conveniently predict the BLCA patient’s survival. We also found that the NRG score was significantly related to the infiltration levels of CD8 T cells, NK cells, and iDC cells, the gene expression of CTLA4, PD-1, TIGIT, and LAG3 of TME, and the sensitivity to chemotherapy and targeted agents in BLCA patients. In conclusion, the NRG score has an excellent performance in evaluating the prognosis, clinicopathologic features, tumor microenvironment (TME), and therapeutic sensitivity of BLCA patients, which could be utilized as a guide for chemotherapy, ICI therapy, and combination therapy.

Abstract
BackgroundThis study aims to evaluate the effectiveness of en bloc resection for patients with nonmuscle invasive bladder cancer (NMIBC) and explore whether a reresection can be avoided after initial en bloc resection.Material and methodsWe conducted research in PubMed, EMBASE, Cochrane Library, and Web of Science up to October 12, 2021, to identify studies on the second resection after initial en bloc resection of bladder tumor (ERBT). R software and the double arcsine method were used for data conversion and combined calculation of the incidence rate.ResultsA total of 8 studies involving 414 participants were included. The rate of detrusor muscle in the ERBT specimens was 100% (95%CI: 100%–100%), the rate of tumor residual in reresection specimens was 3.2% (95%CI: 1.4%–5.5%), and the rate of tumor upstaging was 0.3% (95%CI: 0%–1.5%). Two articles compared the prognostic data of the reresection and non-reresection groups after the initial ERBT. We found no significant difference in the 1-year recurrence-free survival (RFS) rate (OR = 1.44, 95%CI: 0.67–3.09, P = 0.35) between the two groups nor in the rate of tumor recurrence (OR = 0.72, 95%CI: 0.44–1.18, P = 0.2) or progression (OR = 0.98, 95%CI: 0.33–2.89, P = 0.97) at the final follow-up.ConclusionsERBT can almost completely remove the detrusor muscle of the tumor bed with a very low postoperative tumor residue and upstaging rate. For high-risk NMIBC patients, an attempt to appropriately reduce the use of reresection after ERBT seems to be possible.

Abstract
OBJECTIVE To analyze the predictive factors for residual tumors in the second resection after the initial transurethral resection of bladder tumor (TUR-BT) in patients with pT1 tumors and to develop a simple method to predict the probability of residual tumor detection. MATERIAL AND METHODS Patients with pT1 bladder cancer who underwent a second resection within two to six weeks after the initial TUR-BT were included in our retrospective study. The patients' demographics and the tumor characteristics of the initial and second resections were recorded. RESULTS A total of 144 patients were included in our analysis with a 53-month follow-up. In the univariate logistic regression analysis, tumor grade, concomitant carcinoma in situ (CIS), macroscopic appearance of the tumor (solid vs papillary), and presence of a variant histology, were significant risk factors for residual tumor. In the multivariate analysis, tumor grade was the only independent predictor of residual tumor at second TUR (OR: 5.62, 95% CI: 1.228-25.708, p = 0.026). According to our findings, the patients with the highest risk have a 90.9% residual tumor detection probability at the second resection, and the patients with the lowest risk have 25.4%. CONCLUSIONS Tumor grade, macroscopic appearance of the tumor (solid vs papillary), and concomitant CIS, were important predictors of residual tumors at second resection of primary pT1 NMIBC patients. We were able to calculate the probability of residual tumor which helped us determine risk adapted strategies according to these probabilities.

J Clin Med 2022; 11:jcm11175049. [PMID: 36078978 PMCID: PMC9456573 DOI: 10.3390/jcm11175049] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Revised: 08/24/2022] [Accepted: 08/25/2022] [Indexed: 11/16/2022] Open
Abstract
International guidelines recommend repeat transurethral resection of bladder tumors (reTURB) for selected patients with high-risk non-muscle invasive bladder cancer to remove possible residual tumors, restage tumors and improve the therapeutic outcome. However, most evidence supporting the benefits of reTURB is from conventional TURB. The role of reTURB in patients receiving initial En bloc resection of bladder tumor (ERBT) is still unknown. PubMed, Embase, Web of Science, The Cochrane Library, and China National Knowledge Infrastructure (CNKI) were systematically searched. Finally, this systematic review and meta-analysis included twelve articles, including 539 patients. The rates of residual tumor and tumor upstaging detected by reTURB after ERBT were 5.9% (95%CI, 2.0%–11.1%) and 0.0% (95%CI, 0.0%–0.5%), respectively. Recurrence-free survival, tumor recurrence and progression were comparable between patients with and without reTURB after initial ERBT. The pooled hazard ratios of 1-year, 2-year, 3-year and 5-year recurrence-free survival were 0.74 (95%CI, 0.36–1.51; p = 0.40), 0.76 (95%CI, 0.45–1.26; p = 0.28), 0.83 (95%CI, 0.53–1.32; p = 0.43) and 0.83 (95%CI, 0.56–1.23; p = 0.36), respectively. The pooled relative risks of recurrence and progression were 0.87 (95%CI, 0.64–1.20; p = 0.40) and 1.11 (95%CI, 0.54–2.32; p = 0.77), respectively. Current evidence demonstrates that reTURB after ERBT for bladder cancer can detect relatively low rates of residual tumor and tumor upstaging and appears not to improve either recurrence or progression.

Photodynamic diagnosis-assisted transurethral resection using oral 5-aminolevulinic acid decreases residual cancer and improves recurrence-free survival in patients with non-muscle-invasive bladder cancer. Photodiagnosis Photodyn Ther 2022; 38:102838. [PMID: 35381368 DOI: 10.1016/j.pdpdt.2022.102838] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2022] [Revised: 03/17/2022] [Accepted: 03/29/2022] [Indexed: 11/18/2022]
Abstract
BACKGROUND 5-aminolevulinic acid is a protoporphyrin IX precursor used for photodynamic diagnosis. We aimed to clarify the therapeutic benefits of orally administered 5-aminolevulinic acid for photodynamic diagnosis in transurethral resection for non-muscle-invasive bladder cancer in a real-world setting. METHODS From January 2009 to December 2020, patients with non-muscle-invasive bladder cancer who have undergone visually complete resection by initial transurethral surgery were included. Histopathologically confirmed residual and intravesical recurrent bladder cancer was retrospectively investigated and compared with transurethral resection using photodynamic diagnosis and conventional white light. RESULTS One hundred and fifteen patients who underwent photodynamic diagnosis-transurethral resection were compared with 346 patients who underwent white light-transurethral resection. The second transurethral resection revealed that the proportion of residual T1 and Ta bladder cancer was lower in the photodynamic diagnosis group than in the white light group (10.3% vs. 33.8%, P=0.001). Additionally, the proportion of intravesical recurrence was lower in the photodynamic diagnosis group than in the white light group (9.6% vs. 41.9%, P<0.001). Using 5-aminolevulinic acid-photodynamic diagnosis during transurethral resection of bladder tumor improved the cumulative intravesical recurrence-free survival (log-rank test: P<0.001). Furthermore, multivariate analyses indicated that not using 5-aminolevulinic acid-photodynamic diagnosis was an independent predictive factor for residual bladder cancer (odds ratio, 6.16; 95% confidence interval, 2.10-18.0; P<0.001) and intravesical recurrence (hazard ratio, 2.01; 95% confidence interval, 1.05-3.83, P=0.034). CONCLUSIONS Introducing 5-aminolevulinic acid-photodynamic diagnosis into transurethral resection reduces residual bladder cancer and improves the cumulative intravesical recurrence-free survival in patients with non-muscle-invasive bladder cancer, indicating its possible therapeutic benefits.

Abstract
OBJECTIVES To investigate if removing DCE from the Vesical Imaging Reporting and Data System (VI-RADS) influences the diagnostic accuracy of muscle-invasive bladder cancer (MIBC). We also explored using different reference standards on the MRI diagnostic performance. METHODS We searched the Cochrane Library, Embase, and PubMed databases to June 26, 2021. Pooled biparametric MRI (bpMRI, T2WI+DWI) and multiparametric MRI (mpMRI, T2WI+DWI+DCE) sensitivities and specificities and the diagnostic performances of these methods for MIBC were compared using different reference standards. RESULTS Seventeen studies with 2344 patients were finally included, of which 7 studies, including 1041 patients, reported the diagnostic performance of bpMRI. VI-RADS showed sensitivities and specificities of 0.91 (95% CI 0.87-0.94) and 0.86 (95% CI 0.77-0.91) at cutoff scores of 3, and 0.85 (95% CI 0.77-0.90) and 0.93 (95% CI 0.89-0.96) at cutoff scores of 4. BpMRI showed sensitivities and specificities of 0.90 (95% CI 0.69-0.97) and 0.90 (95% CI 0.81-0.95), and 0.84 (95% CI 0.78-0.88) and 0.97 (95% CI 0.87-0.99), respectively, for cutoff scores of 3 and 4. The sensitivities of bpMRI vs mpMRI for MIBC were not significantly different, but bpMRI was more specific than mpMRI at cutoff scores of 3 (p = 0.02) and 4 (p = 0.02). The VI-RADS studies using primary transurethral resection of bladder tumors (TURBT) as the reference standard had significantly higher sensitivities (p < 0.001) than those using secondary TURBT or radical cystectomy as the reference. DATA CONCLUSION BpMRI and conventional VI-RADS had similar diagnostic efficacies for MIBC. Since MRI overestimated MIBC diagnoses using primary TURBT as the reference standard, we recommend using secondary TURBT as the reference standard. KEY POINTS • Biparametric MRI without DCE had similar diagnostic efficacies for MIBC compared with conventional VI-RADS. • The sensitivity of VI-RADS was overestimated when referring to the primary TURBT results. • Biparametric MRI comprised of T2WI and DWI could be used for detecting MIBC in clinical practice.

Abstract
Non-muscle-invasive bladder cancer (NMIBC) is an early-stage cancer without invasion into the detrusor muscle layer. Transurethral resection of bladder tumour (TURBT) is a diagnostic and potentially curative procedure for NMIBC, but has some limitations, including difficulties in ascertaining complete tumour removal upon piecemeal resection and the possibility of tumour re-implantation after the procedure. The oncological control of NMIBC is far from satisfactory, with a 1-year recurrence rate of 15-61%, and a 5-year recurrence rate of 31-78%. Various recurrence mechanisms have been described for NMIBC, such as undetected tumours upon cystoscopy, incomplete resection during TURBT, tumour re-implantation after TURBT, drop metastasis from upper tract urothelial carcinoma and field change cancerization. Understanding the recurrence mechanisms from a clinical perspective has strong implications for the optimization of NMIBC oncological outcomes, as a cure for patients with NMIBC can only be achieved by tackling all possible recurrence mechanisms in a comprehensive manner.

Abstract
Introduction To assess the rate and location of residual tumor in re-transurethral resection of bladder tumor (re-TURBT) and develop a risk stratification tool to assist clinicians in making treatment decisions. Patients and Methods The data of 144 patients with high-risk bladder cancer who received re-TURBT were retrospectively reviewed. The rate and location of residual tumors was recorded. Logistic regression was performed to explore risk factors for residual tumors, and a risk classification tool was developed. Results Among the 144 patients, the rates of residual tumor and tumor location at the base of the primary tumor were 22.2% and 10.4%, respectively. Non-urothelial carcinoma subspecialist, piecemeal resection and the absence of detrusor muscle in the first specimen were defined as risk factors. Patients were categorized into low-, intermediate-, and high-risk groups according to the number of risk factors. The rate of residual tumor in the high-risk group was significantly higher than that in the low- and intermediate-risk groups (50% vs. 7.8%, P=0.001; 50% vs. 18.6%, P=0.002). Moreover, high-risk patients benefitted more from a second resection at the base of the primary tumor due to the high rate of residual tumor located at this site than low- and intermediate-risk patients (23.5% vs. 2.0%, P=0.002; 23.5% vs. 10.2%, P=0.083). Conclusions Risk stratification based on the subspecialist category, operative method, and presence or absence of detrusor muscle in the first specimen could help identify patients who benefit from re-TURBT and second resection the base of the primary tumor.

Abstract
OBJECTIVES To quantify the real-world survival benefit of re-resection vs no re-resection in patients diagnosed with T1 bladder cancer (BC) at the population level. PATIENTS AND METHODS Retrospective population-wide observational cohort study based on pathology reports linked to health administrative data. We identified patients who were diagnosed with T1 BC in the province of Ontario (01/2001-12/2015) and used billing claims to ascertain whether they received re-resection within 2-10 weeks. The time-dependent effect of re-resection on survival outcomes was modelled by Cox proportional hazards regression (unadjusted and adjusted for numerous assumed patient- and surgeon-level confounding variables). Effect measures were presented as hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS We identified 7666 patients of which 2162 (28.7%) underwent re-resection after a median (interquartile range) time of 45 (35-56) days. Patients who received re-resection were less likely to die from any causes (HR 0.68, 95% CI 0.63-0.74, P < 0.001) and from BC (HR 0.66, 95% CI 0.57-0.76, P < 0.001) during any time of follow-up. After adjusting for all assumed confounding variables, re-resection was still significantly associated with a lower overall mortality (HR 0.88, 95% CI 0.81-0.95, P < 0.001), while the association with cancer-specific survival marginally lost its statistical significance (HR 0.87, 95% CI 0.75-1.02, P = 0.08). CONCLUSIONS A second transurethral resection within 2-6 weeks after the initial resection (i.e. re-resection) is recommended for patients diagnosed with primary T1 BC as prior studies suggest therapeutic, diagnostic, and prognostic benefits. However, results on survival endpoints are sparse, conflicting, and often affected by various biases. To the best of our knowledge, the present population-wide study represents the largest cohort of patients diagnosed with T1 BC and provides real-world evidence supporting the utilisation of re-resection in this group of patients.

Abstract
CONTEXT Transurethral resection (TUR) is the mainstay for diagnosis, staging, and treatment of both high-grade and low-grade nonmuscle invasive bladder cancer (NMIBC). It is reported that 51% of initial transurethral resection of bladder tumors (iTURBT) does not contain muscle, which results in higher rates of clinical upstaging on repeat transurethral resection (reTUR) and worse oncologic outcomes. Presence of muscle on iTURBT specimen and performing reTUR within 6 weeks in high-risk NMIBC aids in accurate staging and, therefore, guides proper treatment. OBJECTIVES This study aimed to assess and improve TURBT quality by making surgeons aware of their practice patterns and setting improvement goals. METHODS Patients who received TURBT for a newly diagnosed bladder mass were analyzed by retrospective chart review for 9 months prior to quality improvement (QI) intervention. Data were collected pertaining to muscle presence/absence on biopsy, pathology of the tumor, risk stratification, whether reTUR was indicated, and time to reTUR. The primary endpoints were the presence of muscle on initial TURBT, whether a reTUR was performed when clinically indicated, and time to reTUR. Tumors requiring reTUR were defined as being HGT1 or HGTa >3 cm. The QI intervention, physician education, was then implemented by presenting initial performance results to the physicians, and a second dataset was then collected by prospective analysis for another 9 months to assess for changes in practice patterns. A total of 101 patients receiving TURBT were reviewed, including 52 patients prior to and 49 patients following QI intervention. Patients with a history of, or treatment for, bladder cancer were excluded, along with those without assessment of muscle on pathological analysis. Fisher's exact test was utilized to determine differences in categorical data by comparing each of the following groups prior to and following QI intervention: percent of muscle presence on iTURBT, percent reTUR performed when indicated, and mean time to reTUR in days. A p<0.05 was considered statistically significant. RESULTS After comparing the TURBT results before and after our QI intervention, we found a significant improvement in the number of patients receiving a reTUR when indicated, with 5/13 (38.5%) before compared to 15/19 (78.9%) after, p=0.03. The number of specimens on iTURBT with muscle present were not significantly different, with 38/52 (73.1%) before and 33/49 (67.3%) after, p=0.66. The average time to reTUR before (32.4 days; n=5; range, 21-50 days) and after (42.4 days; n=15; range, 11-77 days) QI intervention was also not significantly different, p=0.28. CONCLUSIONS Our data suggest that critical analysis of physician practice patterns followed by education and setting improvement goals can significantly impact clinical practices and improve quality of care. Future studies will be performed to determine the impact that these changes have on oncologic outcomes.

Abstract
PURPOSE OF REVIEW The role of a re-transurethral resection (TUR) is clearly demonstrated in T1 high-grade nonmuscle invasive bladder cancer. However, its role remains controversial for Ta high-risk tumors and the recent European guidelines stated that the second look procedure could be avoided for these patients despite harboring a high-risk of both disease recurrence and progression. We aimed to evaluate the added benefit on staging, response to bacillus Calmette-Guérin and oncological outcomes of re-TUR in patients with Ta high-grade nonmuscle invasive bladder cancer. RECENT FINDINGS Overall, we identified 15 studies, including 3912 patients from which 743 harbored Ta high-grade disease. Delay between first and second TUR was ranging from 2 to 12 weeks (median 5.6 weeks). The rate of residual disease was 52.8% (range 17-67%). The rate of overall upstaging to T1 and muscle-invasive disease were 10.9 and 4.7%, respectively. Although there was a trend toward improvement of recurrence-free survival outcomes, no definitive conclusions can be drawn due to the retrospective design of the studies included. SUMMARY Residual tumor is common after initial TUR for Ta high-grade. Re-TUR is useful in reducing the rates of residual disease, may improve staging, response to bacillus Calmette-Guérin and oncological outcomes.

Abstract
Simple Summary This report presents clinically relevant advances in the management of non-muscle-invasive bladder cancer, which have been the focus of discussion of expert members of the Spanish Oncology Genitourinary (SOGUG) Multidisciplinary Working Group in the framework of the Genitourinary Alliance project (12GU), designed as a space for the integration of novel information in the care of bladder cancer patients. The present study is focused on different aspects regarding the evaluation of hematuria, assessment of second (or repeated) transurethral resection of bladder cancer, histopathological diagnosis and problems with tumor grading, importance of histological variants, shortage of drug supply, and the current role and influence of immunotherapy and biological markers on the oncological outcome of patients. All proposals and recommendations have a multidisciplinary practical approach and are intended to help clinicians in shared decision making for patients with non-muscle-invasive urothelial cancer. Abstract On the basis of the discussion of the current state of research on relevant topics of non-muscle-invasive bladder cancer (NMIBC) among a group of experts of the Spanish Oncology Genitourinary (SOGUG) Working Group, recommendations were proposed to overcome the challenges posed by the management of NMIBC in clinical practice. A unified definition of the term ‘microhematuria’ and the profile of the patient at risk are needed. Establishing a ‘hematuria clinic’ would contribute to a centralized and more efficient evaluation of patients with this clinical sign. Second or repeated transurethral resection (re-TUR) needs to be defined, including the time window after the first procedure within which re-TUR should be performed. Complete tumor resection is mandatory when feasible, with specification of the presence or absence of muscle. Budding should be used as a classification system, and stratification of T1 tumors especially in extensive and deep tumors, is advisable. The percentage of the high-grade component should always be reported, and, in multiple tumors, grades should be reported separately. Luminal and basal subtypes can be identified because of possibly different clinical outcomes. Molecular subtypes and immunotherapy are incorporated in the management of muscle-invasive bladder cancer but data on NMIBC are still preliminary.

Abstract
BACKGROUND Multiparametric Magnetic Resonance Imaging (mpMRI) has been proposed to add value in the diagnostic pathway of bladder cancer (BC). We wanted to evaluate the performance of mpMRI for muscle-invasion detection in BC patients using a subjective MRI visual T-category and the Vesical Imaging-Reporting and Data System (VI-RADS) score. METHODS This single centre clinical trial included 45 patients with suspected BC (ClinicalTrials.gov Identifier: NCT02662166). All patients had mpMRI prior to transurethral resection of bladder tumour (TUR-BT). The imaging was correlated to histopathological findings. Two individual radiologists evaluated all the mpMRI images. A binary cut-off point for the detection of muscle-invasion in the MRI visual T-category was defined between T1 and T2 and the VI-RADS cut-off score was 3. Cohen's Kappa values were used to evaluate the agreement between the two radiologists. Sensitivity, Specificity, Area Under Receiver Operator Characteristics Curve (AUC), Positive Predictive Value (PPV) and Negative Predictive Value (NPV) were calculated to evaluate the performance of both radiologists separately. RESULTS AUC values for reader A and B using the MRI visual T-category were 0.76 and 0.56, while the corresponding values for VI-RADS were 0.63 and 0.57, respectively. There was no statistically significant difference between the radiologists nor the reporting systems (p > .05) in the detection of muscle-invasion. The inter-reader agreement was substantial (0.61-0.80). CONCLUSION Both the subjective MRI visual T-category and VI-RADS score had only a low to moderate accuracy for the detection of muscle-invasion in BC with no statistically significant difference between the reporting systems.

Abstract
OBJECTIVE To investigate if the use of therapeutic agents for dysuria is a risk factor for the primary recurrence of non-muscle invasive bladder cancer (NMIBC). METHODS First, patients with NMIBC were divided into two groups: the non-recurrence group and the recurrence group. Patient characteristics were compared between both groups. The risk factors of recurrence that were statistically different between the two groups were identified by multivariate analysis. Second, we divided the patients into risk and non-risk groups, and differences in the recurrence-free survival (RFS) between the two groups were analyzed before and after propensity score matching (PSM). RESULTS A total of 162 patients were included, with 84 patients in the non-recurrence group and 78 patients in the recurrence group. In the multivariate analysis, the intake of dysuria agents and bacillus Calmette-Guérin (BCG) therapy were independent factors. The RFS results in terms of the intake of dysuria agents were statistically significant before and after PSM analysis, but no factors were significantly different between the BCG and non-BCG groups after PSM. CONCLUSIONS Therapeutic agents for dysuria might be at an independent risk factor for NMIBC recurrence. This trial is registered with the UMIN Clinical Trials Registry under the number UMIN000036097 (https://upload.umin.ac.jp/cgi-open-bin/ctr/ctr_view.cgi?recptno = R000041122).

Abstract
The Urologic Oncology Journal was founded 25 years ago and we reviewed the literature since that time in the area of urothelial cancer to see the progress and pitfalls we have made over this time period. A comprehensive literature search was conducted by the authors involved who are all actively involved in research, clinical trials, and treatment for urothelial cancer and the results were summarized over the past 25 years. The field of urothelial cancer has evolved tremendously in the last 25 years with the incorporation of molecular subtyping, novel imaging, immunotherapy, and robotic surgery. However, treatments such as BCG and radical cystectomy have remained steadfast over the last 25 years. Although we have a better understanding of the biology of bladder cancer, we still have a long way from being able to cure patients with bladder cancer and eliminate morbidity from treatments. Nevertheless, considerable progress has been made since the founding of the Urologic Oncology Journal 25 years ago.

Abstract
INTRODUCTION Transurethral resection of bladder tumor (TURBT) is a fundamental but challenging step in the diagnosis and treatment of non-muscle invasive bladder cancer (NMIBC). The first- and second-look TURBT are central in the management of T1 tumors. MATERIALS AND METHODS We retrospectively reviewed all patients treated with TURBT for T1 urothelial cell carcinoma (UCC) of the bladder in one academic institution between 2007 and 2017. Quality of TURBT was evaluated based on the presence/absence of muscle on pathology report, the presence/absence of residual tumor on the second look and the occurrence of complications. Patient-, surgeon- and tumor-related factors were investigated for their association with TURBT quality. RESULTS 283 patients were included. Second-look resection was performed after a mean delay of 54 days. Muscle was observed in 85.9% of the samples on the first TURBT. On the second-look resection, UCC was observed in 52.3% of the samples. 38 complications were reported after the first TURBT (13.4%). Surgeon's experience was the only factor significantly associated with occurrence of post-operative complications (OR = 0.40; p = 0.04). Location of the tumor at the bottom of the bladder was a risk factor for not finding muscle at pathological analysis (OR = 0.20; p = 0.06). Male gender, multiplicity and tumor located at the bottom of the bladder were significantly associated with residual disease on reTURBT. In multivariate analysis, only male gender (OR = 4.71; p = 0.02) and tumor multiplicity remained significant (OR for unique tumor = 0.36; p = 0.02). CONCLUSION TURBT is a challenging procedure and surgeon's experience is crucial in reducing the rate of post-operative complications. Technical difficulties resulting from patient's gender, tumor location or number of tumors may be as important as oncological factors in deciding whether or not to perform a second-look resection.

Abstract
Bladder cancer, which is a complex disease, can be treated with a variety of stage-oriented treatment options. In this article, the treatment recommendations of the German S3 guideline "Early detection, diagnosis, treatment and aftercare of bladder cancer" are applied in a fictitious case study. In a patient with invasive transitional cell carcinoma, the treatment options-ranging from bladder preservation to radical cystectomy with neoadjuvant chemotherapy-are discussed on the basis of the current literature.

Green-light laser en bloc resection versus conventional transurethral resection for initial non-muscle-invasive bladder cancer: A randomized controlled trial. Int J Urol 2021; 28:855-860.

Abstract
OBJECTIVE To compare the safety and outcomes between green-light laser en bloc resection and transurethral resection of bladder tumor. METHODS A single-center, randomized controlled trial was carried out from August 2014 to September 2018. Patients with initial non-muscle-invasive bladder cancer were randomized to green-light laser en bloc resection or transurethral resection of bladder tumor. The primary outcomes were pathological findings and perioperative events. The secondary outcome was tumor recurrence. RESULTS A total of 233 patients were randomized to the transurethral resection of bladder tumor group (117 patients) and the green-light laser en bloc resection group (116 patients). The resection time was longer in the green-light laser en bloc resection group (P = 0.022); however, no differences were identified in overall operative time (P = 0.255). Nine patients (7.7%) had an obturator nerve reflex during transurethral resection of bladder tumor. The estimated volume of blood loss was significantly lower in the green-light laser en bloc resection group (P = 0.012). The green-light laser en bloc resection group had a higher rate of T1 bladder cancer (P = 0.031). A total of 104 patients (89.7%) treated with green-light laser en bloc resection had detrusor muscle presence in the specimen, whereas 37 (31.9%) patients had the presence of muscularis mucosae, which was significantly higher than the corresponding number of transurethral resection of bladder tumor patients (P = 0.005 and 0.002, respectively). After a median follow-up period of 48 months, just five patients had tumor recurrence (three in the transurethral resection of bladder tumor group and two in the green-light laser en bloc resection group), and there was no difference between these two groups. CONCLUSIONS Compared with transurethral resection of bladder tumor, green-light laser en bloc resection is more effective due to less obturator nerve reflex and the same recurrence rate. Most importantly, green-light laser en bloc resection can provide better tumor specimens for pathological examinations.

Abstract
AIM To evaluate the use of repeat transurethral resection of the bladder (reTURB) in stage T1 bladder cancer and its impact on treatment and survival in a Norwegian population-based cohort. MATERIAL AND METHODS 1130 patients registered at the Cancer Registry of Norway between 2008 and 2012 with primary urothelial T1 cancer were included. Information on surgical and medical procedures was provided by the Norwegian Patient Registry. Descriptive statistics were used to evaluate characteristics of patients receiving reTURB or not within 12 weeks from primary TURB (primTURB). Survival models identified risk factors and estimated cause-specific survival rates (CSS) adjusted for sex, age, WHO grade, concomitant cis and detrusor muscle at primTURB and treatment. RESULTS The 648 (57%) T1 patients with reTURB were significantly younger and had more WHO high grade tumors compared to those without reTURB. Of 275 patients without detrusor muscle at primTURB 114 (41%) had no reTURB. Of reTURB patients, 45 (7%) had muscle invasive tumor, 110 (17%) T1 and 378 (58%) Ta, cis or T0. Two-thirds of 81 patients receiving early cystectomy after reTURB had T1 or muscle invasive bladder cancer at reTURB. ReTURB did not impact adjusted CSS, but patients with T1 at reTURB had significantly lower CSS than those with < T1 conditions. CONCLUSIONS Almost half of the T1 patients did not undergo reTURB as recommended in guidelines. We show that reTURB makes the histology result more reliable with impact on both treatment and survival. Our results support the use of reTURB as recommended by EAU guidelines.

Abstract
Background The roles of c-KIT and HER2 protein expression in bladder cancer are still debated, and the prognostic value of these proteins as markers of tumor progression is inconclusive. Objective To assess the impact of HER2 and c-KIT protein expressions in the progression of non-muscle-invasive bladder cancer. Methods All patients undergoing transurethral resection of bladder tumors for non-muscle-invasive urothelial carcinoma, with standard regimen of BCG, between January 2017 and November 2019, were evaluated pathologically and immunohistochemically for HER1 and c-KIT proteins in urothelial carcinoma cells. Follow-up cystoscopy was performed for 100 patients every 3 months for the first 2-years and any recurred tumors were excised and examined pathologically, as well as stained for HER2 and c-KIT protein expression. Results HER2 and c-KIT positive expressions were detected in 49% and 38% of cases, respectively. After a mean follow-up of 26.4±7.2 months, the overall recurrence and progression rates were significantly correlated with overexpression of HER2 and c-KIT. In high-grade non-invasive muscle neoplasms, tumor cells showed weak expression for both HER2 and c-KIT proteins, but with progression to muscle-invasion, tumor cells strongly expressed HER2 and lost expression to c-KIT. In the multivariate model, overexpression of HER2 rather than c-KIT protein significantly predicted increased progression. Conclusion Recurrence and progression of non-muscle-invasive bladder cancer correlate with overexpression of HER2 and c-KIT proteins in tumor cells.

ANNALS OF TRANSLATIONAL MEDICINE 2021; 9:761.

Abstract
Background The biological behaviors, clinical treatment, prognosis of non-muscle-invasive bladder cancers (NMIBCs) and muscle-invasive bladder cancers (MIBCs) are distinct. Accurate staging is pivotal in optimal therapy planning for bladder cancers (BCs). However, it is insufficient for urologists in preoperative determining whether the tumor has invaded within the muscularis propria through cystoscope and imaging methods (CT or MRI). Therefore, searching for ideal biomarkers from the tumor tissues and urine is important for identifying the MIBCs preoperatively. Methods Differentially expressed genes between NMIBCs and MIBCs were identified by microarray analysis and validated by quantitative reverse transcription polymerase chain reaction (qRT-PCR) and immunohistochemical analysis. The correlation between cysteine-rich angiogenic inducer 61 (CYR61) expression and Kaplan-Meier test evaluated patients’ overall survival (OS). CYR61 protein levels were measured using enzyme-linked immunosorbent assay (ELISA) in preoperatively collected urine samples from BC patients. The receiver-operating characteristic (ROC) curve analyzed the diagnostic accuracy of uric CYR61. The siRNA mediated silencing of CYR61 in bladder carcinoma cells was performed using Lipofectamine 2000. Cell migration and invasion were assessed using wound healing and transwell assay, respectively. Results Differential gene expression analysis using microarray between 14 MIBCs and 16 NMIBCs human tumor samples revealed a significant increase (P<0.001) in the expression of CYR61 in MIBCs compared with NMIBCs. Higher expression of CYR61 in MIBCs was found in additional 54 tumor samples using qRT-PCR. Therefore, the overexpression of CYR61 in MIBCs could be used as a potential biomarker to distinguish between MIBCs and NMIBCs. ELISA detected elevated levels of CYR61 in the urine samples of MIBC patients (average 2.5-fold) compared with NMIBCs, with 72.7% sensitivity and 86.0% specificity to distinguish MIBCs from NMIBCs. Wound healing and transwell assays using CYR61-silenced carcinoma cells indicated the role of CYR61 in cell migration and invasion. Conclusions CYR61 expression is higher in MIBCs compared with NMIBCs and can serve as a promising biomarker for the preoperative diagnosis of MIBCs with prognostic value; however, multicentric prospective validation is essential for the further evaluation of CYR61.

Abstract
BACKGROUND Guideline indications for restaging transurethral resection (reTUR) for high-grade (HG) Ta bladder tumors vary due to a paucity of data. OBJECTIVE To investigate guideline-based, risk-adapted approaches to reTUR for HG Ta lesions. DESIGN, SETTING, AND PARTICIPANTS An institutional review of HG Ta patients who received adequate bacillus Calmette-Guérin (BCG) from 2000 to 2019 was conducted. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Guideline criteria for reTUR were used to stratify patients. Kaplan-Meier product limits estimated survival. Cox regression and log-rank tests identified association of variables with survival. RESULTS AND LIMITATIONS Of the 209 patients with HG Ta bladder cancer, 104 (50%) underwent reTUR, which identified residual disease in 39 patients (38%). Only one patient (1%) was upstaged to pT1 on reTUR. In all unstratified HG Ta patients, reTUR was associated with improved progression-free survival (p = 0.050) and recurrence-free survival (RFS; p = 0.003). The 5-yr RFS for patients who underwent versus those who did not undergo reTUR based on AUA guidelines was 73% (95% confidence interval 63-81%) versus 52% (40-62%), and for those who underwent versus those who did not undergo reTUR based on EAU guidelines was 76% (61-86%) versus 22% (4-49%). In 45 patients meeting both AUA high-risk criteria (large, multifocal tumors) and EAU criteria (lack of detrusor muscle) for reTUR, lack of restaging was associated with over a two-fold increase in recurrence (67% vs 15%, p = 0.002) and progression (25% vs 6%, p = 0.109). Data were limited by selection bias unaccounted for in selecting candidates for reTUR. CONCLUSIONS Restaging TUR in all HG Ta patients, regardless of risk stratification, was associated with improved outcomes. The benefit of reTUR was most notable in high-risk patients without muscle in the index specimen, consistent with components of both AUA and EAU guidelines. These data support a non-risk-adapted approach to reTUR for all HG Ta lesions. PATIENT SUMMARY Restaging bladder tumor resection improves outcomes in patients with high-grade Ta tumors treated with bacillus Calmette-Guérin (BCG).

Abstract
Background Current non-invasive tests have limited sensitivities and lack capabilities of pre-operative risk stratification for bladder cancer (BC) diagnosis. We aimed to develop and validate a urine-based DNA methylation assay as a clinically feasible test for improving BC detection and enabling pre-operative risk stratifications. Methods A urine-based DNA methylation assay was developed and validated by retrospective single-center studies in patients of suspected BC in Cohort 1 (n = 192) and Cohort 2 (n = 98), respectively. In addition, a prospective single-center study in hematuria patient group (Cohort 3, n = 174) was used as a second validation of the model. Results The assay with a dual-marker detection model showed 88.1% and 91.2% sensitivities, 89.7% and 85.7% specificities in validation Cohort 2 (patients of suspected BC) and Cohort 3 (patients of hematuria), respectively. Furthermore, this assay showed improved sensitivities over cytology and FISH on detecting low-grade tumor (66.7–77.8% vs. 0.0–22.2%, 0.0–22.2%), Ta tumor (83.3% vs. 22.2–41.2%, 44.4–52.9%) and non-muscle invasive BC (NMIBC) (80.0–89.7% vs. 51.5–52.0%, 59.4–72.0%) in both cohorts. The assay also had higher accuracies (88.9–95.8%) in diagnosing cases with concurrent genitourinary disorders as compared to cytology (55.6–70.8%) and FISH (72.2–77.8%). Meanwhile, the assay with a five-marker stratification model identified high-risk NMIBC and muscle invasive BC with 90.5% sensitivity and 86.8% specificity in Cohort 2. Conclusions The urine-based DNA methylation assay represents a highly sensitive and specific approach for BC early-stage detection and risk stratification. It has a potential to be used as a routine test to improve diagnosis and prognosis of BC in clinic.

Abstract
INTRODUCTION Over 1,500 bladder cancers were diagnosed among US Veterans in 2010, the majority of which were non-muscle invasive bladder cancer (NMIBC). Little is known about NMIBC treatment within the Veterans Health Administration. The objective of the study was to assess the quality of care for Veterans with newly-diagnosed NMIBC within Veterans Integrated Service Network (VISN) 02. MATERIALS AND METHODS We used ICD-9 and ICD-10 codes to identify patients with newly-diagnosed bladder cancer from 1/2016-8/2017. We risk-stratified the patients into low, intermediate, and high-risk based on the 2016 American Urological Association Guidelines on NMIBC. Our primary objectives were percentages of transurethral resection of bladder tumors (TURBTs) with detrusor, repeat TURBT in high-risk and T1 disease, high-risk NMIBC treated with induction intravesical therapy (IVT), and responders treated with maintenance IVT. We performed logistic regression for association between distance to diagnosing hospital and receipt of induction IVT in high-risk patients. RESULTS There were 121 newly-diagnosed NMIBC patients; 16% low-risk, 28% intermediate-risk, and 56% high-risk. Detrusor was present in 80% of all initial TURBTs and 84% of high-risk patients. Repeat TURBT was performed in 56% of high-risk NMIBC and 60% of T1. Induction IVT was given to 66% of high-risk patients and maintenance IVT was given to 59% of responders. On multivariate logistic regression, distance to medical center was not associated with receipt of induction IVT (OR = 0.99, 95% CI [0.97,1.01], p = 0.52). CONCLUSIONS We observed high rates of sampling of detrusor in the first TURBT specimen, utilization of repeat TURBT, and administration of induction and maintenance intravesical BCG for high-risk patients among a regional cohort of US Veterans with NMIBC. While not a comparative study, our findings suggest high quality NMIBC care in VA VISN 02.
