The impact of second transurethral resection on survival outcomes in patients with non-muscle-invasive bladder cancer treated with bacillus Calmette-Guérin therapy. Jpn J Clin Oncol 2024; 54:192-200. [PMID: 37974430 PMCID: PMC10849170 DOI: 10.1093/jjco/hyad155] [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: 09/14/2023] [Accepted: 10/24/2023] [Indexed: 11/19/2023] Open
Abstract
OBJECTIVE Several guidelines recommended that second transurethral resection should be performed in patients with diagnosis of high-risk non-muscle-invasive bladder cancer. However, therapeutic benefits of second transurethral resection before bacillus Calmette-Guérin intravesical instillation were conflicting amongst previous studies. We investigated the prognostic impact of second transurethral resection before bacillus Calmette-Guérin instillation in high-risk non-muscle-invasive bladder cancer patients. METHODS This retrospective study included 3104 non-muscle-invasive bladder cancer patients who received bacillus Calmette-Guérin instillations between 2000 and 2019 at 31 collaborative institutions. Univariate and multivariate Cox proportional hazards models were used to assess the risk factors of intravesical recurrence, disease progression, cancer-specific mortality and overall mortality. RESULTS In the entire population, patients undergoing second transurethral resection (33%, 1026/3104) had a lower risk of intravesical recurrence on univariate analysis (hazard ratio 0.85, 95% confidence interval 0.73-0.98, P = 0.027), although it did not remain significant on multivariate analysis (hazard ratio 0.90, 95% confidence interval 0.76-1.07, P = 0.24). Subgroup analysis revealed that, in pT1 patients (n = 1487), second transurethral resection was significantly correlated with a lower risk of intravesical recurrence on multivariate analysis (hazard ratio 0.80, 95% confidence interval 0.64-1.00, P = 0.048), but lower risks of disease progression (hazard ratio 0.75, 95% confidence interval 0.56-1.00, P = 0.049), cancer-specific mortality (hazard ratio 0.54, 95% confidence interval 0.35-0.85, P = 0.007) and overall mortality (hazard ratio 0.73, 95% confidence interval 0.55-0.97, P = 0.027) on univariate analysis. CONCLUSIONS Second transurethral resection confers accurate pathological staging and could be used to safely select good candidates for intravesical bacillus Calmette-Guérin instillation. We further confirm that second transurethral resection could confer an oncological benefit in pT1 bladder cancer patients treated by bacillus Calmette-Guérin instillation, and so strongly recommend second transurethral resection in this patient population.

Prediction of Non-Muscle Invasive Papillary Urothelial Carcinoma Relapse from Hematoxylin-Eosin Images Using Deep Multiple Instance Learning in Patients Treated with Bacille Calmette-Guérin Immunotherapy. Biomedicines 2024; 12:360.

Abstract
The limited reproducibility of the grading of non-muscle invasive papillary urothelial carcinoma (NMIPUC) necessitates the search for more robust image-based predictive factors. In a cohort of 157 NMIPUC patients treated with Bacille Calmette-Guérin (BCG) immunotherapy, we explored the multiple instance learning (MIL)-based classification approach for the prediction of 2-year and 5-year relapse-free survival and the multiple instance survival learning (MISL) framework for survival regression. We used features extracted from image patches sampled from whole slide images of hematoxylin-eosin-stained transurethral resection (TUR) NPMIPUC specimens and tested several patch sampling and feature extraction network variations to optimize the model performance. We selected the model showing the best patient survival stratification for further testing in the context of clinical and pathological variables. MISL with the multiresolution patch sampling technique achieved the best patient risk stratification (concordance index = 0.574, p = 0.010), followed by a 2-year MIL classification. The best-selected model revealed an independent prognostic value in the context of other clinical and pathologic variables (tumor stage, grade, and presence of tumor on the repeated TUR) with statistically significant patient risk stratification. Our findings suggest that MISL-based predictions can improve NMIPUC patient risk stratification, while validation studies are needed to test the generalizability of our models.

EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2023; 49:29-38. [PMID: 35752497 DOI: 10.1016/j.ejso.2022.06.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2022] [Revised: 05/26/2022] [Accepted: 06/04/2022] [Indexed: 02/05/2023]
Abstract
BACKGROUND To reduce recurrence or progression of tumor, NCCN guidelines recommend repeat transurethral resection of bladder tumors (reTURB) for non-muscle-invasive bladder cancer (NMIBC). The study aims to compare the impact of initial TURB and reTURB on the rate of residual or upstaging tumors and short-term and long-term survival outcomes of T1 bladder cancer (BC). MATERIALS AND METHODS We searched through several public database, including PubMed, Embase, Ovid Medline and Ovid EBM Reviews - Cochrane Central Register of Controlled Trials. The latest search time was October 2021. RESULTS In general, 68 articles were involved. Short-term RFS (1-year and 3-year) of reTURB group was better compared with TURB group in T1 patients. The pooled RR were 1.10 (95%CI: 1.01-1.19) and 1.15 (95%CI: 1.03-1.28), respectively. While reTURB did not improve long-term RFS (5-year, 10-year, 15-year) in T1 patients. The pooled RR were 1.12 (95%CI: 0.97-1.30), 1.11 (95%CI: 0.82-1.50) and 1.37 (95%CI: 0.50-3.74), respectively. Analysis of PFS, OS and CSS demonstrated similar outcomes with RFS. We found that about two-thirds of samples contained detrusor. The residual tumor rate in stage T1 was 0.48 (95%CI: 0.42-0.53). While the rate of upstaging in stage T1 was 0.10 (95%CI: 0.07-0.13). CONCLUSIONS In conclusion, reTURB might provide short-term survival benefits for T1 BC, but it was not the same for long-term outcomes. The residual and upstaging rates of T1 BC in reTURB were around 50% and 10%, respectively. Our study might be conducive to clinically informed consents when patients expressed their concerns about the necessity of reTURB and its impact on diagnosis, treatment and prognosis.

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
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
Purpose To evaluate the impact of reresection on the clinical outcome in patients with primary high-risk nonmuscle-invasive bladder cancer (NMIBC) who initially received en bloc transurethral resection. Methods A retrospective analysis of data on eligible high-risk NMIBC with en bloc resection from June 2015 to June 2019 was performed. Patients were divided into two groups based on the presence or absence of reresection after the initial en bloc resection. The primary study endpoint was recurrence-free survival. The secondary outcomes were the residual rate of the tumor after initial en bloc resection, tumor upstaging rate and progression-free survival. Results We identified 115 eligible patients, including 51 (44.3%) who underwent reresection within 6 weeks of the initial en bloc resection and 64 (55.7%) who did not undergo en bloc reresection after the initial en bloc resection. The clinicopathological features were similar in patients with or without reresection. On finding tumor residues after the first en bloc resection, there were 3 cases (5.9%) in the reresection group compared to 2 cases (3.1%) in the non-reresection group (P=0.473). Two patients (3.9%) in the reresection group had tumor progression to muscle-invasive bladder cancer, whereas one patient (1.6%) in the non-reresection group exhibited tumor progression (P=0.430). The 1-year recurrence-free survival rate was 94.1% in the reresection group and 90.6% in the non-reresection group (P=0.269). In multivariate analysis, multifocality and T1 staging were independent prognostic factors for recurrence in patients with high-risk NMIBC who underwent en bloc resection. Conclusion In patients with high-risk NMIBC not exceeding 4 cm in diameter with no more than 4 lesions and not in the anterior bladder wall, reresection after en bloc resection seems to have failed to improve the patient's prognosis. However, a randomized controlled clinical study is required to confirm this hypothesis.

Abstract
Objective: This study aimed to investigate the association between Photodynamic Diagnosis (PDD) with hexaminolevulinate (HAL) and the rate of complete resection and disease persistence at first follow-up cystoscopy for non-muscle-invasive bladder cancer (NMIBC) in UK real-world practice. Methods: Audit data were pooled from six UK centres where HAL PDD was used in patients with a new NMIBC diagnosis undergoing transurethral resection of bladder tumours (TURBT) since 2008. Patients received adjunctive intra-vesical therapy and surveillance in line with European and UK guidelines, including early re-resection in high-grade NMIBC. Results: PDD-assisted TURBT was done in 837 patients with new NMIBC. The detrusor muscle was present in 69.4% of cases. At early re-TURBT in 207 high-risk patients, 13.0% had residual disease. Multifocal disease was the most significant factor in increasing the rate of residual disease (odds ratio excluding cases of CIS=4.1; 95% confidence interval 1.5–11.3). The recurrence rate at first follow-up cystoscopy (RRFFC) was 10.6% (8.9% in patients with complete initial TURBT). In the historical cohort undergoing good-quality white-light TURBT, RRFFC was 31%; 40.5% of high-risk patients had residual disease at early re-TURBT. Conclusion: HAL PDD may increase the rates of complete resection, reducing the risk of early recurrence and the need for routine re-resection in high-grade NMIBC. Level of evidence: 2b.

Abstract
Between Expert Reliability refers to the extent to which different experts examining identical evidence make the same observations and reach the same conclusions. Some areas of expert decision making have been shown to entail questions with relatively low Between Expert Reliability, but the disagreement between experts is not always communicated to the legal actors forming decisions on the basis of the expert evidence. In this paper, we discuss the issues of Between Expert Reliability in legal proceedings, using forensic age estimations as a case study. Across national as well international jurisdictions, there is large variation in which experts are hired to conduct age estimations as well as the methods they use. Simultaneously, age estimations can be fully decisive for outcomes e.g. in asylum law and criminal law. Using datasets obtained from the Swedish legal context, we identify that radiologists and odontologists examining knees or teeth images to estimate age seem to disagree within their own disciplines (radiologist 1 v. radiologist 2 or odontologist 1 v. odontologist 2) as well as across different disciplines (radiologist v. odontologist) relatively often. This may have large implications e.g. in cases where only one expert from the respective field is involved. The paper discusses appropriate ways for legal actors to deal with the possibility of lacking Between Expert Reliability. This is indeed a challenging task provided that legal actors are legal experts but not necessarily scientific experts.

Abstract
OBJECTIVE To confirm frozen section (FS) method for muscularis propria (MP) sampling and to compare the FS method with the ReTUR section (RS) procedure to reduce needing for second resection that can cause waste of time for definitive treatment of muscle-invasive bladder cancer. METHODS A total of 27 patients who admitted to our clinic and was performed transurethral resection of bladder tumor (TUR-BT) due to bladder tumor and had an indication of ReTUR were evaluated prospectively in the study. During the first TUR-BT procedure (as permanent section), FS examination was also performed to the patients. ReTUR was performed 2-6 weeks after the first TUR-BT procedure. RESULTS Presences of MP were observed in 51.8% and 77.7% of FS and permanent section examinations. In the comparing of the presence of residual tumor in the methods, although 12 of 27 patients were found to have a residual tumor in FS, it was found to be in only 6 of 12 patients in RS. There was no statistical significance between FS and RS methods for MP sampling and detecting of residual tumor. CONCLUSIONS FS was found to be a comparable method with the RS method (ReTUR procedure) for the sampling of MP and detecting of residual tumor, despite the limitations in the pathological examination FS. Especially in patients with detected residual tumor after the pathological consultation of FS during the procedure, re-resection can be a choice at the end of the first TUR-BT instead of ReTUR.

[PMID: 32220105 DOI: 10.1002/jmri.27141] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2019] [Revised: 03/03/2020] [Accepted: 03/03/2020] [Indexed: 11/08/2022] Open
Abstract
BACKGROUND The Vesical Imaging-Reporting and Data System (VI-RADS) is a newly developed system of bladder cancer staging with multiparametric MRI (mpMRI), which can be used to predict the presence of muscle invasion for bladder cancer. PURPOSE To evaluate the accuracy of three mpMRI series (T2 WI, diffusion-weighted imaging [DWI], and dynamic contrast-enhanced image [DCEI]) and VI-RADS for diagnosing the muscle invasive bladder cancer (MIBC). STUDY TYPE Retrospective. POPULATION In all, 66 pathologically proven bladder cancers in 32 patients. FIELD STRENGTH/SEQUENCE Before the diagnostic MRI with an intramuscular antispasmodic agent, optimal bladder distension was confirmed. 3.0T MRI with T2 WI, DWI, and DCEI. ASSESSMENT Three reviewers independently assessed and scored the bladder cancers in T2 WI, DWI, and DCEI using a five-point score system. Based on the scores in the three sequences, reviewers scored each bladder cancer with reference to VI-RADS categories. We evaluated the diagnostic performance of each of three mpMRI sequences and the final VI-RADS categorization for diagnosing MIBC. STATISTICAL TESTS Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and the area under the curve (AUC) of each of three sequences separately and VI-RADS categorization for diagnosing the MIBC. RESULTS The diagnostic performances of each of the three mpMRI series and VI-RADS for diagnosing MIBC were excellent. Especially using the optimal cutoff score >3 for predicting MIBC on DWI, DCEI, and VI-RADS, the sensitivity, specificity, PPV, NPV, and AUC values were 90% (95% confidence interval [CI]: 0.56, 1.00), 100% (95% CI: 0.94, 1.00), 100% (95% CI: 0.66. 1.00), 98.3% (95% CI: 0.91, 1.00), and 0.95, respectively. DATA CONCLUSION: mpMRI based on VI-RADS can stratify patients with bladder cancer according to the presence of muscle invasion. LEVEL OF EVIDENCE 3. TECHNICAL EFFICACY STAGE 2. J. Magn. Reson.

Therapeutic benefit of second-look transurethral resection of bladder tumors for newly diagnosed T1 bladder cancer: a single-center experience. Int Urol Nephrol 2019; 51:1335-1342. [PMID: 31129781 DOI: 10.1007/s11255-019-02172-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2019] [Accepted: 05/13/2019] [Indexed: 01/13/2023]
Abstract
PURPOSE In recent years, second-look transurethral resection of bladder tumors (TURBT) has been recommended for patients with stage T1 bladder cancer after the initial TURBT for restaging and deciding the subsequent treatment. However, we believe that second-look TURBT has therapeutic benefits, such as low incidence of recurrence and progression. Therefore, we compare the differences in long-term outcome between patients who did and did not accept second-look TURBT for stage T1 bladder cancer. METHODS We assessed 504 patients diagnosed with urothelial carcinoma who underwent initial TURBT between January 2012 and December 2016 at a single medical center; of these patients, 177 were diagnosed with T1 bladder cancer during the initial TURBT, and we excluded no muscle from the specimen in the initial TURBT. The patients were categorized into groups 1 and 2 based on the acceptance of second-look TURBT, which was performed within 4-14 weeks after the initial TURBT. Group 1 underwent second-look TURBT, but group 2 did not. Both groups were followed-up for recurrence-free survival (RFS) and progression-free survival (PFS), and the risk factors for recurrence and progression were analyzed. RESULTS In total, 93 (52.5%) patients in group 1 underwent second-look TURBT, and 84 (47.5%) in group 2 did not. The 2-year RFS rates were 74.6% and 60.0% and the PFS rates were 91.2% and 87.5% in groups 1 and 2, respectively. CONCLUSION This study demonstrated higher recurrence-free and progression-free survival rates for patients who underwent second-look TURBT. This result emphasizes the importance of second-look TURBT in stage T1 bladder cancer not only for restaging but also for therapeutic benefit.

Differences in Pathologic Results of Repeat Transurethral Resection of Bladder Tumor (TURBT) according to Institution Performing the Initial TURBT: Comparative Analyses between Referred and Nonreferred Group. BIOMED RESEARCH INTERNATIONAL 2018; 2018:9432606. [PMID: 30271788 PMCID: PMC6146742 DOI: 10.1155/2018/9432606] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 04/08/2018] [Revised: 08/06/2018] [Accepted: 08/16/2018] [Indexed: 12/22/2022]
Abstract
Objective Although transurethral resection of bladder tumor (TURBT) is a standard treatment and determines staging for nonmuscle invasive bladder cancer, many deficiencies persist. There is a risk of upstaging and residual cancer when repeat TURBT is performed. Authors compared the results of repeat TURBT by institution performing the initial TURBT. Methods We retrospectively reviewed the medical records of 289 patients who underwent repeat TURBT within 2-6 weeks after initial TURBT between 1998 and 2013. The patients were divided into the referred group and the nonreferred group by institution performing the initial TURBT. And we analyzed the intergroup differences in residual tumor and upstaging rate and the factors significantly correlated with residual tumor. Results The mean age was 69.6 ± 11.1 years and the mean follow-up was 49.7 (range: 0–191) months. The referred group included 69 patients, while the nonreferred group included 220 patients. The referred group included 57 (82.6%) patients with residual tumor after repeat TURBT. Overall upstaging occurred in 15 (21.7%), and upstaging to T2 occurred in 11 (15.9%) of the initial Ta and T1 patients. In the nonreferred group, there were 123 (55.9%) patients with residual tumor. Overall upstaging occurred in 10 (4.5%) and upstaging to T2 occurred in 7 (3.2%) patients. Conclusions Gross hematuria, grade, and tumor quantity and size were significantly associated with residual cancer on multivariate analysis. In the referred group, repeat TURBT and restaging are necessary.

Abstract
PURPOSE To evaluate the performance of multiparametric MRI (mpMRI) for the local staging of bladder cancer following transurethral resection of bladder tumor. METHODS This Institutional Review Board-approved, retrospective study identified 45 patients with pathology-proven bladder cancer who underwent transurethral resection followed by mpMRI between August 2011 and October 2016. Two radiologists reviewed each MRI independently and assigned T and N stage. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were calculated for the presence of muscle invasion (T2 or higher), peri-vesical invasion (T3 or higher), and regional nodal disease compared to findings at cystectomy as the reference standard. Inter-observer agreement was measured using Cohen's κ coefficient. RESULTS Of 45 patients, 13% were stage T2, 27% T3, 16% T4; of 40 patients, 28% had regional nodal disease. Sensitivity, specificity, PPV, NPV, and accuracy of mpMRI for readers 1 and 2, respectively, were muscle invasion, 92% and 88%, 74% and 84%, 81% and 88%, 88% and 84%, 84% and 86%; peri-vesical invasion, 72% and 67%, 92% and 92%, 87% and 86%, 81% and 79%, 83% and 81%; regional nodal disease, 45% and 45%, 93% and 90%, 71% and 63%, 82% and 81%, 80% and 78%. Inter-observer agreement was good using all sequences. CONCLUSIONS mpMRI was both sensitive and specific in the detection of muscle invasive bladder cancer, and was specific but not sensitive for both peri-vesical invasion and nodal involvement. mpMRI may have a role at locally staging bladder cancer following transurethral resection.

Abstract
BACKGROUND Neoadjuvant chemotherapy (NAC) has been shown to improve survival in patients with urothelial carcinoma (UC). However, there are a subset of patients who do not respond or progress despite systemic treatment. METHODS Data from the National Cancer Database on patients who underwent a radical cystectomy (RC) with or without NAC from 2006 to 2013 were abstracted. Covariates were balanced using inverse probability weighting methods. The primary outcome of overall survival in patients with residual disease by stage was evaluated using 90-day conditional landmark analysis and Cox proportional hazards modeling. Secondary outcome of predictors of residual disease was evaluated using multivariable logistic regression analysis. RESULTS A total of 20,128 patients met our inclusion criteria; 16,058 patients underwent RC only (80%) and 4070 underwent RC with NAC (20%). Patients who received NAC were younger and healthier, treated at an academic center, and presented with higher stage. NAC was associated with improved overall survival amongst patients with cT3-4aN0 (HR 0.84 95% CI 0.73-0.97; p = 0.02) and cN+ (HR 0.70, 95% CI 0.58-0.86; p = 0.001). Predictors of no residual disease were NAC (OR 0.17, 95% CI 0.14-0.21; p < 0.001) and treatment at an academic facility (OR 0.47, 95% CI 0.37-0.60; p < 0.001). Patients with cT3-4a or cN+ had increased odds of having residual UC (OR 2.01, 95% CI 1.53-2.64; p < 0.001, and OR 2.14, 95% CI 1.43-3.21; p < 0.001, respectively) compared with cT2. CONCLUSION In patients with residual UC, NAC is associated with a significant survival benefit in higher stage disease only. Furthermore, those treated with NAC or at an academic center were less likely to have residual disease. Given the toxicity of NAC, more prudent patient selection for NAC is warranted and requires further study.

Abstract
CONTEXT Initial treatment for most bladder cancers (BCs) involves transurethral resection (TUR) or tumours. Often more cancer is found after the initial treatment in around half of patients, requiring a second resection. Repeat transurethral resection (reTUR) is recommended for high-risk, non-muscle-invasive bladder cancer (NMIBC) to remove any residual disease and improve cancer outcomes. OBJECTIVE To systematically review the practice and therapeutic benefit of an early reTUR for high-risk NMIBC. EVIDENCE ACQUISITION A systematic review of original articles was performed using PubMed/Medline and Web of Science databases in December 2016 (initial) and October 2017 (final). We searched the references of included papers. EVIDENCE SYNTHESIS We screened 15 209 manuscripts and selected 31 detailing 8409 persons with high-grade Ta and T1BC for inclusion. Detrusor muscle was found at initial TUR histology in 30-100% of cases. Residual tumour at reTUR was found in 17-67% of patients following Ta and in 20-71% following T1 cancer. Most residual tumours (36-86%) were found at the original resection site. Upstaging occurred in 0-8% (Ta to ≥T1) and 0-32% (T1 to ≥T2) of cases. Conflicting data report the impact of reTUR on subsequent recurrence and cancer-specific mortality. Recurrence for Ta was 16% in the reTUR group versus 58% in the non-reTUR group. For T1, recurrence ranged from 18% to 56%, but no clear trend was identified between reTUR and control. No clear relationship between reTUR and progression was found for Ta, although for T1 rates were higher in the non-reTUR group in series with control populations (5/6 studies). Overall mortality was slightly reduced in the reTUR group in two studies with controls (22-30% vs 26-36% [no reTUR]). CONCLUSIONS Residual tumour is common after TUR for high-risk NMIBC. The reTUR helps in the diagnosis of this residual cancer and may improve outcomes for cancers initially staged as T1. PATIENT SUMMARY Some bladder cancers (BCs) are aggressive but confined to the bladder surface. Initial treatment includes endoscopic resection. More cancer is found after the initial treatment in approximately half of patients. In the aggressive but confined group of BC, a second resection, a few weeks after the first, may help find this residual cancer and improve outcomes, although the evidence quality for this is weak.

Abstract
The prognostic value of repeat transurethral resection of bladder tumor (TURBT) in patients with diagnosed high-risk, non-muscle-invasive bladder cancer (NMIBC) was investigated. We retrospectively reviewed the medical records of patients treated from October 2004 to December 2013 at Seoul National University who underwent repeated TURBT within 2–6 weeks after an initial resection. The study enrolled patients who had been diagnosed with NMIBC at both the initial and repeat TURBT; patients with muscle-invasive tumors on repeat TURBT were excluded. We used stepwise multivariate Cox regression models stratified by study to assess the independent effects of the predictive factors and estimated hazard ratios (HRs) from the Cox models. We investigated a total of 198 patients who were diagnosed with high-risk NMIBC. In logistic regression analyses, number of bladder tumors (2–7: OR, 2.319; 8≤: OR, 3.353; p<0.05), initially high tumor grade (OR, 2.435; p = 0.040), and presence of carcinoma in situ lesion (OR, 3.639; p = 0.017) correlated with residual tumor in the repeated-TURBT specimen. T1 stage in repeated-TURBT significantly correlated with recurrence (HR, 1.837; p = 0.010) and progression (HR, 2.806; p = 0.029) in multivariate analysis. The high grades of tumors in repeated-TURBT also significantly correlated with progression but not recurrence in the multivariate analysis (HR 2.152; p = 0.008). In this study, the pathologic findings in repeated-TURBT correlated with recurrence and progression in high-risk NMIBC. Repeated-TURBT is valuable because it can predict the recurrence and progression of high-risk NMIBC in addition to obtaining accurate pathologic findings.

Abstract
Purpose This study was designed to estimate the value of a second transurethral resection of bladder tumor (TURBT) procedure in patients with initially diagnosed T1 high-grade bladder cancer. Materials and Methods Between August 2009 and January 2013, a total of 29 patients with T1 high-grade bladder cancer prospectively underwent a second TURBT procedure. Evaluation included the presence of previously undetected residual tumor, changes to histopathological staging or grading, and tumor location. Recurrence-free and progression-free survival curves were generated to compare the prognosis between the groups with and without residual lesions by use of the Kaplan-Meier method. Results Of 29 patients, 22 patients (75.9%) had residual disease after the second TURBT. Staging was as follows: no tumor, 7 (24.1%); Ta, 5 (17.2%); T1, 6 (20.7%); Tis, 6 (20.7%); Ta+Tis, 1 (3.4%); T1+Tis, 1 (3.4%); and ≥T2, 3 (10.3%). The muscle layer was included in the surgical specimen after the initial TURBT in 24 patients (82.7%). In three patients whose cancer was upstaged to pT2 after the second TURBT, the initial surgical specimen contained the muscle layer. In the group with residual lesions, the 3-year recurrence-free survival and 3-year progression-free survival rates were 50% and 66.9%, respectively, whereas these rates were 68.6% and 68.6%, respectively, in the group without residual lesions. This difference was not statistically significant. Conclusions Initial TURBT does not seem to be enough to control T1 high-grade bladder cancer. Therefore, a routine second TURBT procedure should be recommended in patients with T1 high-grade bladder cancer to accomplish adequate tumor resection and to identify patients who may need to undergo prompt cystectomy.

Abstract
INTRODUCTION We aimed to evaluate the long-term recurrence and progression rates in a Turkish population with high-grade Ta and T1 bladder cancer and to determine malign potential of high-grade Ta bladder cancer. METHODS 191 patients who had non-invasive bladder cancer were evaluated at a single institution between 2005 and 2010. Median follow-up was 55.6 months (13-108). Long-term follow-up results of recurrence and progression rates of high-grade Ta and T1 were analyzed and compared with each other. RESULTS Of the 191 patients, 143 (74.9%) were high-grade T1 and 48 (25.1%) were high-grade Ta. Of the 143 patients who were high-grade T1, 39 (27.2%) responded to the induction BCG without recurrence. 33 (23%) patients had invasion deep into the muscle layer. 61 (42%) patients had recurred as high-grade T1. Of the 48 patients who were high-grade Ta, 15 (31%) responded to induction BCG without recurrence. 18 (37.5%) patients had recurrence as high-grade Ta. 12 (25%) patients had invasion deep into to the muscle layer. Of all the patients, 13 (7%) patients died of causes related to bladder cancer. In a multivariate analysis, concomitant CIS was statistically significant for the progression of high-grade Ta bladder cancer (p<0.005). CONCLUSIONS According to the data of the current study, the presence of concomitant CIS in patients with high-grade bladder cancers is associated with a higher risk of progression. There is a need for larger scale multi-institutional studies in order to support the hypothesis that high-grade Ta tumors should be considered as T1 tumors.

Abstract
Approximately 70%-80% of urothelial carcinomas are detected at the stage of non-muscle-invasive bladder cancer (NMIBC). Initial management is often successful, but recurrence is common and leads to a long, burdensome, costly disease course. The quality and efficiency of care depends in part on accurate, clearly communicated descriptions of tumor characteristics. This review identifies current best practices, unmet needs, and key issues in the pathology of NMIBC for the practicing urologist. Reasonable and objective recommendations are provided with the goal of improving urologist-pathologist communication, the efficiency of healthcare utilization, and outcomes for patients with NMIBC.

Abstract
The rate of clinical understaging in non-muscle invasive bladder cancer (NMIBC) after an initial transurethral resection (TUR) is significant, particularly for high-grade disease, and this has a major impact on prognosis. A repeat TUR, 2 to 6 weeks following the initial resection, is recommended in appropriately selected cases to avoid diagnostic inaccuracy and improve treatment allocation. This article summarizes the rationale and indications for performing a repeat TUR in NMIBC and also provides information regarding patient selection and technique.

Abstract
BACKGROUND Second medical opinions have become commonplace and even mandatory in some health-care systems, as variations in diagnosis, treatment or prognosis may emerge among physicians. OBJECTIVE To evaluate whether physicians' judgment is affected by another medical opinion given to a patient. DESIGN Orthopedic surgeons and neurologists filled out questionnaires presenting eight hypothetical clinical scenarios with suggested treatments. One group of physicians (in each specialty) was told what the other physician's opinion was (study group), and the other group was not told what it was (control group). PARTICIPANTS A convenience sample of 332 physicians in Israel: 172 orthopedic surgeons (45.9% of their population) and 160 neurologists (64.0% of their population). MEASUREMENTS Scoring was by choice of less or more interventional treatment in the scenarios. We used χ(2) tests and repeated measures ANOVA to compare these scores between the two groups. We also fitted a cumulative ordinal regression to account for the dependence within each physician's responses. RESULTS Orthopedic surgeons in the study group chose a more interventionist treatment when the other physician suggested an intervention than those in the control group [F (1, 170) =4.6, p=0.03; OR=1.437, 95% CI 1.115-1.852]. Evaluating this effect separately in each scenario showed that in four out of the eight scenarios, they chose a more interventional treatment when the other physician suggested an intervention (scenario 1, p=0.039; scenario 2, p<0.001; scenario 3, p=0.033; scenario 6, p<0.001). These effects were insignificant among the neurologists [F (1,158) =0.44, p=0.51; OR=1.087, 95% CI 0.811-1.458]. In both specialties there were no differences in responses by level of clinical experience [orthopedic surgeons: F (2, 166) =0.752, p=0.473; neurologists: F (2,154) =1.951, p=0.146]. CONCLUSIONS The exploratory survey showed that in some cases physicians' judgments may be affected by other physicians' opinions, but unaffected in other cases. Weighing previous opinions may yield a more informed clinical decision, yet physicians may be unintentionally influenced by previous opinions. Second opinion has the potential to improve the clinical decision-making processes, and mechanisms are needed to reconcile discrepant opinions.

Abstract
Bladder cancer is the most common malignancy of the urinary tract. About 75%-85% of patients present with non-muscle-invasive bladder cancer (NMIBC). However, patients with pT1 tumors, as well as all those with high-grade disease, make up a subset with a high-risk of recurrence and disease progression. Although still regarded as the gold standard, clinical evidence from contemporary published series clearly demonstrates that transurethral resection of tumor (TUR) is a procedure far from optimal, highlighting its limitations and the need for further diagnostic accuracy. Routine use of a restaging TUR (re-TUR), supported by the American Urological Association and European Association of Urology guidelines, detects residual tumor in a significant number of cases after initial TUR. It provides a more accurate staging of the disease and, consequently, helps to guide its treatment. Recent years have seen rapid development of novel optical techniques aimed to optimize resection. Routine implementation of these novel techniques in the context of re-TUR is promising and may potentially result in more tumors being identified and completely resected, leading to significantly lower residual tumor rates than with the standard white-light TUR. This article will focus on re-TUR in the management of high-risk NMIBC, with an up-to-date review of the available literature and detailed analysis of the published series.

Abstract
BACKGROUND AND PURPOSE Transurethral resection of the bladder (TURB), the first step in treatment of patients with urothelial bladder cancers, is limited by technicalities, surgeon skill, and random chance. When high-risk superficial diseases are discovered, a repeated TURB is indicated. We reviewed current literature and performed a meta-analysis of the role of repeated TURB in the management of nonmuscle-invasive bladder cancers. METHODS PubMed, MEDLINE, ISI Web of Knowledge, EBSCO, EMBASE, and Biomed Central databases were searched for reports in English from 1980 to June 2010. The end point was prevalence of persistent urothelial bladder cancer of any stage and grade at repeated TURB, assessed separately for T(a) and T(1) lesions at TURB. Persistence was presence at repeated TURB of same or lower stage cancer as at TURB; upstaging was presence of higher stage. RESULTS There were 2327 original articles and 562 reviews retrieved. Data from 15 studies were pooled and analyzed. Prevalence of T(1) was reported in all and of T(a) in 8. Persistence rate prevalence at repeated TURB was 0.39 (95% confidence interval [CI]=0.26 to 0.54) for T(a) and 0.47 (95% CI=0.41 to 0.53) for T(1). Persistence was 19.4% to 56% and 15.2% to 55%, and upstaging occurred in 0% to 14.3% of T(a) and 0% to 24.4% of T(1) at repeated TURB, respectively. CONCLUSION High percentages of persistence and upstaging confirm a repeated TURB is needed in patients with high-risk nonmuscle-invasive bladder cancer. Further investigation is encouraged taking risk stratification into consideration to evaluate the role of repeated TURB in low- and mid- risk diseases.

Abstract
T1 high-grade (formerly T1G3) bladder cancer is a challenging clinical entity representing approximately 10-15% of all new bladder cancer cases. The variable natural history of the disease and possible impairment in quality of life associated with radical treatment makes T1 high-grade one of the most challenging uro-oncological patient groups to manage. In particular, the risk of clinical understaging and not recognizing muscle-invasive disease may have detrimental effects on patient outcome. The cornerstone of contemporary staging is restaging transurethral resection (TUR), which helps in defining further management. In patients with restaging TUR stage less than T1, induction bacillus Calmette-Guérin combined with maintenance offers good results. The option of radical cystectomy should be discussed with patients with restaging TUR stage T1 or higher and it is highly recommended to all patients with recurrent T1 of carcinoma in situ during bacillus Calmette-Guérin maintenance. In addition to restaging TUR stage, several other clinicopathological factors, such T1 substaging, associated carcinoma in situ, tumor size and appearance, lymphovascular invasion, and hydronephrosis, aid in the decision making between radical and conservative treatment. Future prospects include improved staging and molecular markers that may guide toward conservative therapy or allow more cT1 patients to be offered nerve-sparing cystectomies and neobladders and, thus, improving quality of life for patients undergoing radical surgery.

Abstract
Purpose To investigate whether narrow band imaging (NBI)-assisted transurethral resection (TUR) (NBI-TUR) has an impact on non-muscle invasive bladder cancer (NMIBC) residual tumour rate compared to white light (WL)-assisted TUR (WL-TUR). Methods Patients with NMIBC treated with either NBI- or WL-TUR were compared in a frequency-matched index-control setting. During NBI-TUR, all suspicious lesions identified by either WL or NBI were resected. Index patients (NBI-TUR, n = 40) were prospectively recruited and control patients (WL-TUR, n = 120) were retrospectively collected, whilst being blinded for their first follow-up (fFU)-status. Non-radical TUR cases, patients without evidence of urothelial carcinoma in the pathology specimen and those with isolated carcinoma in situ or muscle invasive disease were excluded. Matching was based on the risk of tumour recurrence defined by (a) the EORTC risk score for recurrence and (b) the administration or not of one single chemotherapeutic intravesical instillation immediately after TUR. All patients underwent routine follow-up with WL cystoscopy supplemented with cytology at 3 months or re-TUR in selected cases. The residual tumour rates at fFU (RR-fFU) of patients with NMIBC submitted to either NBI- or WL-TUR were compared. Results Baseline patient and tumour characteristics were comparable between groups. The RR-fFU for WL- and NBI-TUR was 30.5% (36 out of 118 patients) and 15.0% (6 out of 40 patients), respectively (OR: 2.7, one-sided 95% CI: 1.2–6.1; P = 0.03). Conclusion NBI-TUR decreases residual tumour rate significantly when compared to a matched cohort of WL-TUR.
