Adenocarcinoma of the Bladder: Assessment of Survival Advantage Associated With Radical Cystectomy and Comparison With Urothelial Bladder Cancer. Urol Oncol 2023; 41:326.e9-326.e16. [PMID: 36882338 DOI: 10.1016/j.urolonc.2023.01.015] [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: 11/10/2022] [Revised: 12/16/2022] [Accepted: 01/16/2023] [Indexed: 03/07/2023]
Abstract
PURPOSE To evaluate the association between radical cystectomy (RC) and cancer-specific mortality (CSM) in patients diagnosed with adenocarcinoma of the bladder (ACB). Moreover, to directly compare the survival advantage of RC between ACB vs. urothelial bladder cancer (UBC). MATERIALS AND METHODS Non-metastatic muscle-invasive ACB and UBC patients were identified within Surveillance, Epidemiology, and End Results database (SEER 2000-2018). All analyses were stratified between RC vs. no-RC, in either organ-confined (OC: T2N0M0) or non-organ-confined (NOC: T3-4N0M0 or TanyN1-3M0) stages. Propensity score matching (PSM), cumulative incidence plots, competing risks regression (CRR) analyses, and 3 months' landmark analyses were performed. RESULTS Overall, 1,005 ACB and 47,741 UBC patients were identified, of whom 475 (47%) and 19,499 (41%) were treated with RC, respectively. After PSM, comparison between RC vs. no-RC applied to 127 vs. 127 OC-ACB, 7,611 vs. 7,611 OC-UBC, 143 vs. 143 NOC-ACB, and 4,664 vs. 4,664 NOC-UBC patients. 36-month CSM rates in RC vs. no-RC patients were 14 vs. 44% in OC-ACB, 18 vs. 39% in OC-UBC, 49 vs. 66% in NOC-ACB, and 44 vs. 56% in NOC-UBC patients. In CRR analyses, the effect of RC on CSM yielded a hazard ratio of 0.37 in OC-ACB, of 0.45 in OC-UBC, of 0.65 in NOC-ACB and of 0.68 in NOC-UBC patients (all P values<0.001). Landmark analyses virtually perfectly replicated the results. CONCLUSIONS In ACB, regardless of stage, RC is associated with lower CSM. The magnitude of this survival advantage was greater in ACB than in UBC, even after control for immortal time bias.

Mehr JP, Bates JN, Lerner SP. Is There A Benefit of Restaging Transurethral Resection of Bladder Tumor Prior to Radical Cystectomy With or Without Neoadjuvant Chemotherapy? Bladder Cancer 2023; 9:41-48.

Abstract
BACKGROUND One of the best predictors of positive outcomes in bladder cancer (BC) is pT0 following radical cystectomy (RC). Discordance between clinical and pathologic staging affects decision-making in patients with clinical absence of disease (cT0). OBJECTIVES We sought to determine whether a restaging transurethral resection of bladder tumor (re-TURBT) improves clinical staging accuracy relative to pathologic stage RC in patients treated with neoadjuvant chemotherapy (NAC) versus those who did not receive NAC. METHODS We queried our prospectively maintained IRB approved institutional database to identify 129 patients who underwent RC from 2013 to 2019 with a re-TURBT prior to RC. 53 patients were treated with NAC between their initial and re-TURBT and 76 patients were not treated with NAC. RESULTS The overall upstaging rate from re-TURBT to RC was 34.9%. There was no significant difference in the upstaging rate between the NAC and no-NAC groups - 31.0% vs. 37.0%, respectively. In patients who were cT0 on re-TURBT, the NAC group did not show a significantly greater rate of pathologic clinical CR (pT0) than the no NAC group - 38.5% vs. 37.5%, respectively. Re-TURBT with staging < rT2 as a predictor for absence of MIBC on pathologic staging ( CONCLUSIONS Re-TURBT after NAC does not show statistically significant improvement in staging accuracy relative to pathologic stage at RC compared to re-TURBT in patients not treated with NAC.

[PMID: 36441069 DOI: 10.1016/j.urolonc.2022.09.026] [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: 03/23/2022] [Revised: 09/21/2022] [Accepted: 09/23/2022] [Indexed: 11/06/2022]
Abstract
BACKGROUND Initial tumour staging in bladder cancer mainly relies on the histo-pathological outcome of the transurethral bladder tumour resection (TURBT) and imaging by means of a CT-scan (CT-intravenous urography; CT-IVU). The reported risk of understaging varies from 24-50%. To further improve the the evaluation of depth of invasion of the bladder tumour the application of magnetic resonance imaging (MRI) may be useful. To substantiate the additional value of this imaging modality the present observational study was designed. STUDY DESIGN This is a prospective observational study to analyse bladder tumour staging with multiparametric magnetic resonance imaging (mpMRI) in patients with a known bladder tumour, who are planned for radical cystectomy. STUDY POPULATION Patients with an invasive bladder cancer who are planned for radical cystectomy. INTERVENTION Patients were accrued during their visit to the outpatient department of urology. They underwent routine cystoscopy, laboratory tests (including serum Creatinin) and CT-IVU investigations and subsequently a mpMRI. MAIN STUDY PARAMETERS/ENDPOINTS To demonstrate the value of mpMRI in the initial staging of bladder tumours using radiological bladder tumour stage (T-stage) based on mpMRI and pathological bladder tumour stage based on 'whole-mount' histo-pathology after radical cystectomy. RESULTS Thirty-seven participants with known bladder tumours underwent mpMRI and subsequent cystectomy. After mpMRI 10 participants were diagnosed with non-muscle-invasive bladder cancer (NMIBC) and 27 participants with muscle-invasive bladder cancer (MIBC). In the 'whole-mount' pathology results 12 participants had NMIBC and 25 participants had MIBC. We found a sensitivity and specificity of 0.88 en 0.58 respectively, for the evaluation of MIBC. The positive and negative predictive value were 81% and 70% respectively. The diagnostic accuracy of mpMRI to differentiate between NMIBC and MIBC was 78%. CONCLUSIONS We found a sensitivity of 88% and a specificity of 58% for mpMRI to discriminate NMIBC from MIBC.

Implications for pelvic lymph node irradiation in definitive chemoradiotherapy of node negative muscle invasive bladder cancer based on predictive factors of clinicopathologic discrepancy. J Cancer Res Clin Oncol 2022; 149:2537-2542. [PMID: 35764702 DOI: 10.1007/s00432-022-04153-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2022] [Accepted: 06/13/2022] [Indexed: 11/30/2022]
Abstract
PURPOSE To identify pre-surgical imaging predictive value and factors associated with the clinicopathologic discrepancy for implication of definitive pelvic radiotherapy in clinically node-negative bladder cancer. METHOD The documented data of bladder cancer patients who underwent radical cystectomy plus pelvic lymphadenectomy were collected retrospectively. Patients' characteristics, last imaging, pathology reports, disease-specific survival and overall survival were retrieved. RESULTS From 142 patients, pre-surgical imaging had a sensitivity of 76.4%, specificity of 73.7%, positive predictive value (PPV) of 94.9%, and negative predictive value (NPV) of 32.6% (p value < 0.0001) for detection of muscle invasion. Also, for detection of positive lymph nodes, imaging had a sensitivity of 31.8%, specificity of 85.7%, PPV of 50%, and NPV of 73.7% (p value: 0.022). 44.4% of study population were upstaged after surgery (24.6% associated with N-upstaging) and 18.3% were downstaged (12% associated with N-downstaging). Receipt of neoadjuvant chemotherapy and T-stage were not correlated with N-upstaging. On multivariate analysis, lymphovascular invasion (LVI) maintained its significance for independent prediction of upstaging (OR 3.3, 95% CI 1.5-7.5, p value: 0.004) and inversely with downstaging (OR 0.34, 95% CI 0.12-0.96, p value: 0.04). Older age (OR 1.03, 95% CI 1.0-1.05, p value 0.047), positive margins (OR 2.1, 95% CI 1.2-3.8, p value 0.011), presence of LVI (OR 2.5, 95% CI 1.4-4.7, p value 0.003), perineural invasion (OR 2.0, 95% CI 1.2-3.4, p value 0.013), and lymph node ratio (OR 1.011, 95% CI 1.001-1.021, p value 0.03) were associated with worse survival. Also, N-upstaging independently predicted a worse survival after controlling for surgical pathology stage (OR 2.3, 95% CI 1.2-4.5, p value 0.011). CONCLUSIONS The optimal target volume in definitive chemoradiotherapy of node-negative bladder cancer patients remains to be established. Since then, customizing the treatment is considered especially for positive LVI in TURBT specimen.

Abstract
BACKGROUND The preoperative lymph node (LN) staging of bladder cancer (BCa) addresses the subsequent therapeutic strategy and influences patient's prognosis. However, sparce evidence exists regarding the accuracy of conventional cross-sectional imaging, such as computed tomography or magnetic resonance imaging, in correctly detect LN status. We aimed to assess the diagnostic accuracy of conventional cross-sectional imaging in detecting preoperative LN involvement among BCa patients treated with radical cystectomy and pelvic lymph node dissection. METHODS We retrospectively analyzed data of 1,104 patients who underwent preoperative LN staging with computed tomography or magnetic resonance imaging and subsequent radical cystectomy with pelvic lymph node dissection for BCa between 1997 and 2017 at three tertiary referral centers. Patients receiving neoadjuvant chemotherapy were excluded. We assessed the concordance between clinical (cN) and pathological LN (pN) status, defined as the accuracy of imaging in detecting LN involvement using pathological specimen as reference; concordance was expressed according to Cohen's kappa coefficient. Location-based sub-analyses were performed, distinguishing among external iliac, intern iliac, obturator, common iliac, presacral and paraaortic LNs. RESULTS Among 870 cN0 patients, 68.9% were confirmed pN0 at pathological report; while among 234 cN+ patients, 50.5% were found with LN metastases at pathological specimen. Overall, conventional imaging showed slight concordance (64.9%) between cN and pN stages (sensitivity: 30%; specificity: 84%). At sub-analysis, no agreement between cN and pN status was found in each LN location, with the only exception of common iliac LNs with slight concordance (37.5%). Common iliac LNs achieved the highest sensitivity and positive likelihood ratio (15% and 2.4, respectively) compared to other LN locations. CONCLUSIONS Overall, preoperative cross-sectional imaging exhibited a slight concordance between cN and pN status. Our location-based sub-analyses showed unsatisfactory results in each LN location- Thus, nomograms combining morphological patterns with serological and clinicopathological features are urgently required.

Abstract
Approximately 25% of the patients with muscle-invasive bladder cancer (MIBC) who are clinically node negative have occult lymph node metastases at radical cystectomy (RC) and pelvic lymph node dissection. The aim of this study was to evaluate preoperative CT-based radiomics to differentiate between pN+ and pN0 disease in patients with clinical stage cT2-T4aN0-N1M0 MIBC. Patients with cT2-T4aN0-N1M0 MIBC, of whom preoperative CT scans and pathology reports were available, were included from the prospective, multicenter CirGuidance trial. After manual segmentation of the lymph nodes, 564 radiomics features were extracted. A combination of different machine-learning methods was used to develop various decision models to differentiate between patients with pN+ and pN0 disease. A total of 209 patients (159 pN0; 50 pN+) were included, with a total of 3153 segmented lymph nodes. None of the individual radiomics features showed significant differences between pN+ and pN0 disease, and none of the radiomics models performed substantially better than random guessing. Hence, CT-based radiomics does not contribute to differentiation between pN+ and pN0 disease in patients with cT2-T4aN0-N1M0 MIBC.

Prognostication in Japanese patients with Bacillus Calmette-Guérin-unresponsive non-muscle-invasive bladder cancer undergoing early radical cystectomy. Int J Urol 2021; 29:242-249. [PMID: 34902876 DOI: 10.1111/iju.14759] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Revised: 11/09/2021] [Accepted: 11/18/2021] [Indexed: 11/28/2022]
Abstract
OBJECTIVES The US Food and Drug Administration recently defined the clinical term "Bacillus Calmette-Guérin-unresponsive non-muscle-invasive bladder cancer" as a disease state resistant to adequate Bacillus Calmette-Guérin therapy. There is a significant lack of prognostication for this disease even in patients who have undergone early radical cystectomy. This study aimed to identify the clinical outcomes and prognostic factors in Japanese patients with Bacillus Calmette-Guérin-unresponsive non-muscle-invasive bladder cancer who underwent early radical cystectomy. METHODS Data from a large-scale multicenter retrospective study included 2879 patients with highest-risk or high-risk non-muscle-invasive bladder cancer who received intravesical Bacillus Calmette-Guérin induction therapy between January 2000 and December 2019. A total of 141 patients (4.3%) met the criteria for Bacillus Calmette-Guérin-unresponsive disease, of whom 47 (33.3%) underwent early radical cystectomy. Prognostic factors for three clinical endpoints, namely, unresectable lesion-free survival, cancer-specific survival, and overall survival, were identified. RESULTS The highest-risk status at induction Bacillus Calmette-Guérin was associated with short unresectable lesion-free survival (hazard ratio 7.85; P < 0.05), cancer-specific survival (hazard ratio 12.24; P < 0.05), and overall survival (hazard ratio 9.25; P < 0.01). Moreover, extravesical tumors (pathological T3 or T4) on the radical cystectomy specimens were associated with poor prognosis and were found at a higher rate in patients with the highest-risk status at induction Bacillus Calmette-Guérin than in those with high-risk status (35.7% vs 21.2%). CONCLUSIONS The highest-risk status among the pre-Bacillus Calmette-Guérin factors was associated with upstaging to extravesical tumors and poor prognosis despite early radical cystectomy procedures. Appropriate decision-making and the correct timing of radical cystectomy are vital to avoid treatment delays and improve outcomes.

Abstract
INTRODUCTION We sought to describe the incidence, risk factors, and survival outcomes associated with pathological upstaging from non-muscle invasive bladder cancer (NMIBC) to muscle invasive bladder cancer (MIBC) after robot-assisted radical cystectomy (RARC). METHODS We reviewed the International Robotic Cystectomy Consortium database between 2004 and 2020. Upstaging was defined as ≥pT2 or pN+ at final pathology from clinical <T2N0M0. Descriptive statistics were used to summarize data. Cochran-Armitage test was used to depict upstaging trend over time. Multivariate regression models were used to depict variables associated with upstaging. Kaplan Meier curves were used to describe disease-specific (DSS), recurrence-free (RFS), and overall survival (OS). RESULTS 463 patients underwent RARC for NMIBC. Upstaging occurred in 145 (31%) patients. Upstaged patients were older (70 vs 67 years, p <0.01), more likely to have American Society of Anesthesiologists score (≥3) (55% vs 44%, p=0.04) and had higher rate of preoperative hydronephrosis (26% vs 10%, p <0.01). They were more likely to have positive surgical margins (10% vs 3%, p= 0.01), recurrences (28% vs 9%, p<0.01), and to receive adjuvant/salvage treatment (26% vs none, p <0.01). On multivariate analysis, upstaging was associated with older age (OR 1.04; CI 1.01-1.07, p<0.01), cT1 vs cTis (OR 4.25; CI 1.57-11.48, p <0.01), cT1 vs cTa (OR 2.92; CI 1.40-6.06, p<0.01), and preoperative hydronephrosis (OR 3.18; CI 1.60-6.32, p<0.01). Upstaged patients had worse 5-year RFS (53 % vs 85%, log rank p<0.01), DSS (66% vs 93%, log rank p<0.01), and OS (49% vs 74%, log rank p<0.01). The rate of upstaging did not significantly change over time (38% in 2004 to 27% in 2019, p=0.17). CONCLUSION Upstaging to MIBC occurred in a significant proportion of patients after RARC for NMIBC and was associated with worse survival outcomes. Older patients, those with cT1 disease and hydronephrosis were more likely to upstage.

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
PURPOSE OF REVIEW Accurate staging of bladder cancer is essential to guide appropriate management. In this review, we discuss the principles, applications and performance of multiparametric MRI (mpMRI) and PET-computer tomography (PET-CT) for local and distant staging of bladder cancer. RECENT FINDINGS Bladder mpMRI has a high diagnostic performance in local staging of bladder cancer, superior to other imaging modalities. It can accurately differentiate muscle invasive bladder cancer (MIBC) from non-MIBC (NMIBC), as well as ≤T2 from ≥T3 stages. mpMRI can be used to assess pelvic lymph nodes, although its sensitivity is relatively low. For the assessment of the upper urinary tract, CT urography is the imaging modality of choice. magnetic resonance urography is a viable alternative to CT in selected cases. Although PET-CT is accurate for nodal and distant staging of bladder cancer, there is no clear evidence on its superior diagnostic performance compared with contrast-enhanced CT. SUMMARY mpMRI is the most accurate imaging modality for local staging of bladder cancer, capable to accurately distinguish MIBC from NMIBC. Nodal and distant staging relies primarily on contrast-enhanced CT.

Can preoperative imaging characteristics predict pT3 bladder cancer following cystectomy? World J Urol 2020; 39:1941-1945.

Abstract
PURPOSE Imaging characteristics in bladder cancer (BC), such as hydronephrosis, are predictive of ≥ pT3 disease at time of radical cystectomy (RC). The predictive capacity of other findings, such as perivesical stranding (PS), remains unclear. We investigated whether PS was associated with ≥ pT3 BC in patients who did not receive neoadjuvant chemotherapy (NAC). METHODS We identified 433 patients with BC who underwent RC from 2003 to 2018 of which 128 did not receive NAC. Evidence of PS on pre-TURBT imaging was determined by radiologist review and a stranding grading system was created. Factors associated with PS and hydronephrosis were identified. Multivariable logistic regressions evaluated PS and hydronephrosis as predictors for ≥ pT3 BC. RESULTS Of the 128 patients who did not receive NAC, 48 (38%) had pT3 and 12 (9%) had pT4 BC. 125 (98%) patients had CT and three (2%) had MRI. PS and hydronephrosis on imaging were identified in 19 (15%) and 45 (35%) patients. PS was not associated with imaging type (p = 0.38), BMI (p = 0.18), or pathologic T stage (p = 0.24). Hydronephrosis was more frequently associated with higher pathologic T stage (p = 0.034). Multivariable analysis demonstrated that PS was not predictive of ≥ pT3 BC (p = 0.457), while hydronephrosis was positively associated (p = 0.003). Stratification by grade of stranding did not improve the predictive capacity of PS (p = 0.667). CONCLUSION While hydronephrosis is an indicator of higher stage BC, PS failed to be a reliable predictor of ≥ pT3 stage. These observations should give pause in using PS on imaging to guide decisions until further investigations can be explored.

Abstract
Accurate staging of bladder cancer (BC) is critical, with local tumor staging directly influencing management decisions and affecting prognosis. However, clinical staging based on clinical examination, including cystoscopy and transurethral resection of bladder tumor (TURBT), often understages patients compared to final pathology at radical cystectomy and lymph node (LN) dissection, mainly due to underestimation of the depth of local invasion and the presence of LN metastasis. MRI has now become established as the modality of choice for the local staging of BC and can be additionally utilized for the assessment of regional LN involvement and tumor spread to the pelvic bones and upper urinary tract (UUT). The recent development of the Vesical Imaging-Reporting and Data System (VI-RADS) recommendations has led to further improvements in bladder MRI, enabling standardization of image acquisition and reporting. Multiparametric magnetic resonance imaging (mpMRI) incorporating morphological and functional imaging has been proven to further improve the accuracy of primary and recurrent tumor detection and local staging, and has shown promise in predicting tumor aggressiveness and monitoring response to therapy. These sequences can also be utilized to perform radiomics, which has shown encouraging initial results in predicting BC grade and local stage. In this article, the current state of evidence supporting MRI in local, regional, and distant staging in patients with BC is reviewed. LEVEL OF EVIDENCE: 3 TECHNICAL EFFICACY STAGE: 2 J. Magn. Reson.

Abstract
OBJECTIVE The aim of the present study was to evaluate the influence of preoperative hydronephrosis and ureteral orifice involvement (UOI) on survival of patients undergoing radical cystectomy (RC) for bladder cancer (BC). MATERIAL AND METHODS A total of 162 patients with BC underwent RC between January 2006 and March 2017. Patients were divided into two groups for both presences of preoperative hydronephrosis and orifice involvement at final pathology. Additionally, tumors with orifice involvement were subgrouped histopathologically after RC as those with only UOI and those with invasive to the ureter with an additional concurrent site at final pathology. RESULTS Preoperative hydronephrosis was detected in 57 patients. Preoperative and postoperative creatinine on month 3 were higher in the preoperative hydronephrosis (+) group (p<0.001). In addition, postoperative T stage, surgical margin positivity, invasion of urethra, and pathological upstaging were higher in this group. Cancer-specific survival (CSS) and overall survival (OS) were better in the hydronephrosis (-) group than in the hydronephrosis (+) group (p=0.001 and p=0.001, respectively). Preoperative hydronephrosis was found to be an independent factor in pathological upstaging. Patients were divided into two groups according to the presence of UOI. Group 1 consisted of patients without UOI, and group 2 with UOI. Preoperative hydronephrosis, hydronephrosis grade, and T stage were statistically higher in tumors with UOI. Moreover, CSS and OS were lower in group 2 than in group 1. CONCLUSION Preoperative hydronephrosis and UOI are predicting factors on survival of patients undergoing RC for BC. Preoperative hydronephrosis was found to be an independent factor in pathological upstaging.

Abstract
Lymph node involvement in bladder cancer is common and has prognostic implications. Early and accurate identification of metastatic lymph nodes is, therefore, important in ensuring appropriate patient triage and management. The purpose of this review is to provide a pictorial and educational overview of the staging and imaging appearance of metastatic lymph nodes in bladder cancer. Additionally, a secondary aim of this manuscript is to provide a review of the diagnostic accuracy of common imaging modalities available for detecting metastatic lymph nodes in affected patients.

Abstract
CONTEXT Management of bladder cancer (BC) is primarily driven by stage, grade, and biological potential. Knowledge of each is derived using clinical, histopathological, and radiological investigations. This multimodal approach reduces the risk of error from one particular test, but may present a staging dilemma when results conflict. Multiparametric magnetic resonance imaging (mpMRI) may improve patient care through imaging of the bladder with better resolution of the tissue planes than computed tomography and without radiation exposure. OBJECTIVE To define a standardized approach to imaging and reporting mpMRI for BC, by developing a VI-RADS score. EVIDENCE ACQUISITION We created VI-RADS (Vesical Imaging-Reporting And Data System) through consensus using existing literature. EVIDENCE SYNTHESIS We describe standard imaging protocols and reporting criteria (including size, location, multiplicity, and morphology) for bladder mpMRI. We propose a five-point VI-RADS score, derived using T2-weighted MRI, diffusion-weighted imaging, and dynamic contrast enhancement, which suggests the risks of muscle invasion. We include sample images used to understand VI-RADS. CONCLUSIONS We hope that VI-RADS will standardize reporting, facilitate comparisons between patients, and in future years, will be tested and refined if necessary. While we do not advocate mpMRI for all patients with BC, this imaging may compliment pathology or reduce radiation-based imaging. Bladder mpMRI may be most useful in patients with non-muscle-invasive cancers, in expediting radical treatment or for determining response to bladder-sparing approaches. PATIENT SUMMARY Magnetic resonance imaging (MRI) scans for bladder cancer are becoming more common and may provide accurate information that helps improve patient care. Here, we describe a standardized reporting criterion for bladder MRI. This should improve communication between doctors and allow better comparisons between patients.

Abstract
PURPOSE To evaluate the oncological impact of postponing radical cystectomy (RC) to allow further conservative therapies prior to progression in a large multicentre retrospective cohort of T1-HG/G3 patients initially treated with BCG. METHODS According to the time of RC, the population was divided into 3 groups: patients who did not progress to muscle-invasive disease, patients who progressed before radical cystectomy and patients who experienced progression at the time of radical cystectomy. Clinical and pathological outcomes were compared across the three groups. RESULTS Of 2451 patients, 509 (20.8%) underwent RC. Patients with tumors > 3 cm or with CIS had earlier cystectomies (HR = 1.79, p = 0.001 and HR = 1.53, p = 0.02, respectively). Patients with tumors > 3 cm, multiple tumors or CIS had earlier T3/T4 or N + cystectomies. In patients who progressed, the timing of cystectomy did not affect the risk of T3/T4 or N + disease at RC. Patients with T3/T4 or N + disease at RC had a shorter disease-specific survival (HR = 4.38, p < 0.001), as did patients with CIS at cystectomy (HR = 2.39, p < 0.001). Patients who progressed prior to cystectomy had a shorter disease-specific survival than patients for whom progression was only detected at cystectomy (HR = 0.58, p = 0.024) CONCLUSIONS: Patients treated with RC before experiencing progression to muscle-invasive disease harbor better oncological and survival outcomes compared to those who progressed before RC and to those upstaged at surgery. Tumor size and concomitant CIS at diagnosis are the main predictors of surgical treatment while tumor size, CIS and tumor multiplicity are associated with extravesical disease at surgery.

Abstract
PURPOSE The detection of lymph node metastases in bladder cancer has a significant impact on treatment decisions. Multiple imaging modalities are available to clinicians including magnetic resonance imaging, computed tomography and positron emission tomography. We aimed to investigate the utility of alternate imaging modalities on pre-cystectomy imaging in bladder cancer for the detection of lymph node metastases. METHODS We performed systematic search of Web of Science (including MEDLINE), EMBASE and Cochrane libraries in accordance with the PRISMA statement. Studies comparing lymph node imaging findings with final histopathology were included in our analysis. Sensitivity and specificity data were quantified using patient-based analysis. A true positive was defined as a node-positive patient on imaging and node positive on histopathology. Meta-analysis of studies was performed using a mixed-effects, hierarchical logistic regression model. RESULTS Our systematic search identified 35 articles suitable for inclusion. MRI and PET have a higher sensitivity than CT while the specificity of all modalities was similar. The summary MRI sensitivity = 0.60 (95% CI 0.44-0.74) and specificity = 0.91 (95% CI 0.82-0.96). Summary PET/CT sensitivity = 0.56 (95% CI 0.49-0.63) and specificity = 0.92 (95% CI 0.86-0.95). Summary CT sensitivity = 0.40 (95% CI 0.33-0.49) and specificity = 0.92 (95% CI 0.86-0.95). CONCLUSION MRI and PET/CT provides superior sensitivity compared to CT for detection of positive lymph nodes in bladder cancer prior to cystectomy. There is variability in the accuracy that current imaging modalities achieve across different studies. A number of other factors impact on detection accuracy and these must be considered.

Radiomics-guided therapy for bladder cancer: Using an optimal biomarker approach to determine extent of bladder cancer invasion from t2-weighted magnetic resonance images. Adv Radiat Oncol 2018; 3:331-338. [PMID: 30202802 PMCID: PMC6128093 DOI: 10.1016/j.adro.2018.04.011] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2018] [Accepted: 04/28/2018] [Indexed: 01/09/2023] Open
Abstract
Background Current clinical staging methods are unable to accurately define the extent of invasion of localized bladder cancer, which affects the proper use of systemic therapy, surgery, and radiation. Our purpose was to test a novel radiomics approach to identify optimal imaging biomarkers from T2-weighted magnetic resonance imaging (MRI) scans that accurately classify localized bladder cancer into 2 tumor stage groups (≤T2 vs >T2) at both the patient level and within bladder subsectors. Method and Materials Preoperative T2-weighted MRI scans of 65 consecutive patients followed by radical cystectomy were identified. A 3-layer, shell-like volume of interest (VOI) was defined on each MRI slice: Inner (lumen), middle (bladder wall), and outer (perivesical tissue). An optimal biomarker method was used to identify features from 15,834 intensity and texture properties that maximized the classification of patients into ≤T2 versus >T2 groups. A leave-one-out strategy was used to cross-validate the performance of the identified biomarker feature set at the patient level. The performance of the feature set was then evaluated at the subsector level of the bladder by dividing the VOIs into 8 radial sectors. Results A total of 9 optimal biomarker features were derived and demonstrated a sensitivity, specificity, accuracy of prediction, and area under a receiver operating characteristic curve of 0.742, 0.824, 0.785, and 0.806, respectively, at the patient level and 0.681, 0.788, 0.763, and 0.813, respectively, at the radial sector level. All 9 selected features were extracted from the middle shell of the VOI and based on texture properties. Conclusions An approach to select a small, highly independent feature set that is derived from T2-weighted MRI scans that separate patients with bladder cancer into ≤T2 versus >T2 groups at both the patient level and within subsectors of the bladder has been developed and tested. With external validation, this radiomics approach could improve the clinical staging of bladder cancer and optimize therapeutic management.

Abstract
There are currently no reported randomized trials that characterize the staging or therapeutic benefit of performing a lymph node dissection in either bladder cancer or upper tract urothelial carcinoma. Several unanswered questions remain in this domain focused on the indications and patient selection for pelvic lymph node dissection, extent of dissection, its impact on outcome, and potential risks. However, the results of observational studies suggest that the burden of metastasis is high in both diseases when muscle invasive and performing a lymphadenectomy can provide prognostic information and yield therapeutic benefit.

Abstract
A meta-analysis was performed to evaluate the accuracy of optical coherence tomography (OCT) for diagnostic accuracy studies in bladder cancer patients. English language studies reporting the diagnostic accuracy of OCT for bladder cancer were retrieved from the PubMed, EMBASE and Cochrane Library databases in December 2014. Histopathology was a reference standard. Sensitivities, specificities, positive likelihood ratios and negative likelihood ratios were calculated, and summary receiver operating characteristic curves were drawn to determine the diagnostic accuracy of OCT. Finally, 9 eligible studies (468 patients) were included in our meta-analysis. The pooled sensitivity, specificity, positive likelihood ratio and negative likelihood ratio of OCT were 0.96 [95% confidence interval (CI): 0.94-0.98], 0.82 (95% CI: 0.80-0.85), 6.83 (95% CI: 3.24-14.1) and 0.05 (95% CI: 0.02-0.16), respectively. The summary diagnostic odds ratio was 138.88 (95% CI: 29.63-650.89) and the overall area under the curve was 0.9735. These results suggest that OCT has excellent diagnostic performance in patients with bladder cancer and recurrent lesions.

Abstract
To compare the detection of bladder neoplasms and image quality among the diffusion-weighted imaging (DWI) acquired by the prototype single-shot echo-planar-imaging (ss-EPI) sequence for integrated slice-specific dynamic shimming (iShim), readout segmentation of long variable echo trains (RESOLVE) and conventional ss-EPI sequences.Around 63 patients with 77 bladder lesions were enrolled. The MR protocol included T1WI, T2WI and 3 types of DWI. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of each DWI for the detection of bladder tumor were computed. The subjective scores of imaging quality, diagnostic confidence, and detection of tumors of stage T2 or greater were recorded. The contrast-to-noise ratio (CNR), signal intensity ratios, and apparent diffusion coefficient (ADC) values were measured. The univariate analysis of variance technique, the Friedman test, and Bland-Altman plots were used in the statistical analysis. Observer performance of tumor T stage was tested using receiver operating characteristic (ROC) curve analysis.The sensitivity, NPV, and accuracy of iShim (92.75%; 61.54%; 93.51%) for detection of bladder tumor were superior to those of RESOLVE (84.06%; 42.11%; 85.71%) and ss-EPI (86.96%; 47.06%; 88.31%). All qualitative scores of iShim were higher than RESOLVE (all P < .05) and ss-EPI (all P < .05). The CNR, signal intensity ratios between bladder lesion and urine, lesion, and submucosal stalk (or nearby normal bladder wall), and between distal normal bladder wall and urine of iShim (39.84 ± 12.11, 2.40 ± 0.60, 1.98 ± 0.43, 1.28 ± 0.16) were higher than RESOLVE (16.97 ± 7.08, 1.62 ± 0.41, 1.52 ± 0.42, 1.15 ± 0.29, all P < .05) and ss-EPI (27.89 ± 9.65, 1.66 ± 0.46, 1.57 ± 0.50, 0.99 ± 0.22, all P < .05). No significant difference of ADC values were found for iShim and RESOLVE (P=0.46), iShim, and ss-EPI (P = 0.97), RESOLVE and ss-EPI (P = .48). The Az value for the detection of tumors of stage T2 or greater was slightly higher with the iShim DWI sequence (0.89) than with the RESOLVE (0.87, P = 0.72) or ss-EPI (0.85, P = .38) sequence.The iShim DWI has relatively better detection of bladder tumor and image quality without significant ADC value difference.

Abstract
Objective To determine the role of neutrophil-to-lymphocyte ratio (NLR) in prognosticating survival outcomes in patients with advanced/metastatic urothelial bladder cancer. Methods We retrospectively reviewed 84 patients undergoing radical cystectomy (RC) for UCB from January 2002 to June 2012. NLR was computed (median: 5 days) prior to surgery. No patients received neoadjuvant chemotherapy. NLR was analyzed as a continuous variable and a cut-off point of 2.7 was obtained, with a statistical receiver operating characteristics of 0.74. Kaplan–Meier curves, multivariate Cox proportional hazard and logistics regression models were used to predict NLR association with survival outcomes. Results The median follow-up period was 30.1 months (range: 3.2–161.7) owing to high recurrence rate and subsequent mortalities, compared to the median 64.7 months in patients alive at the end of study period. NLR ≥2.7 was associated with worse survival outcomes (5-year disease-specific survival: 22% vs 58%, p = 0.017, 95%CI: 1.193–6.009; 5-year overall survival: 23% vs 60%, p = 0.008, 95%CI: 1.322–6.147). Furthermore, on multivariate analyses, higher NLR was independently associated with higher recurrence rate (p = 0.007, HR =6.999, 95%CI: 1.712–28.606), higher T staging (p = 0.021, HR = 3.479, 95%CI: 1.212–9.990) and lymph node involvement (p = 0.009, HR = 4.534, 95%CI: 1.465–14.034). Conclusion This study suggests that NLR can be an inexpensive novel factor for patients risk stratification pre-operatively. This improves patient counseling and identifies patients who may benefit from multimodal treatment.

Abstract
Administration of neoadjuvant chemotherapy preceding radical cystectomy in patients with bladder cancer remains a matter of debate. Results of prospective, randomized studies have demonstrated an overall absolute survival benefit of 5% at 5 years, provided cisplatin-based combination regimens are used. Owing to the perception of a modest survival benefit, the medical community has been slow to adopt the use of neoadjuvant chemotherapy. Other reasons for the underuse of neoadjuvant chemotherapy range from patient ineligibility to fear of delaying potentially curative surgery in nonresponders. Instead, several institutions have adopted an individualized, risk-adapted approach, in which the decision to administer chemotherapy is based on clinical stage and patient comorbidity profile. The development of new cytotoxic and targeted therapies, in particular immune checkpoint inhibitors, warrants well-designed prospective studies to test their efficacy alone or in combination in the neoadjuvant setting. Moving forward, genomic characterization of muscle-invasive bladder cancer could offer information that aids clinicians in selecting the appropriate chemotherapy regimen. Following neoadjuvant therapy, every effort should be made to ensure optimal surgery, as surgical margins and the number of removed lymph nodes are prognostic factors; thus, radical cystectomy and a meticulous extended pelvic lymph node dissection should be performed by expert surgeons.

Abstract
Introduction: Level I evidence supports the use of cisplatin-based neoadjuvant chemotherapy (NAC) for muscle-invasive bladder cancer prior to radical cystectomy (RC). On average, 30–40% of patients achieve a complete pathologic response (i.e., stage pT0) after receiving NAC. Some centers risk-stratify patients, suggesting that there may be a higher-risk population that would derive the most benefit from NAC. Recently, a risk-stratification model developed at M.D. Anderson Cancer Center (MDACC) specified criteria for clinical staging and patient selection for NAC. We applied this model to our own RC patient cohort and evaluated our own experience with clinical risk stratification and the effect of NAC on post treatment risk categories. Methods: We retrospectively reviewed the charts of consecutive patients who underwent RC at two institutions between 2004 and 2014 and noted whether or not they received NAC. We determined the clinical stage by reviewing the exam under anesthesia, transurethral resection biopsy (TURBT) pathology, and preoperative imaging. Patients with cT2-T4a node-negative disease were included. Those with sarcomatoid features or adenocarcinoma were excluded. Patients were classified as high risk if they had tumor-associated hydronephrosis, clinical stage≥T3b-T4a disease, variant histology (i.e., micropapillary or small cell), or lymphovascular invasion (LVI), as specified by the MDACC model. Variables were examined for associations with cancer-specific survival (CSS), overall survival (OS), and risk-category reclassification. Results: We identified 166 patients with a median follow-up time of 22.2 months. In all, 117 patients (70.5%) did not receive NAC, 68 (58.1%) of whom we classified as high risk. Among patients not receiving NAC, CSS and OS were significantly decreased in high-risk patients (log-rank test p = 0.01 for both comparisons). The estimated age-adjusted hazard ratios of high-risk classification for cancer-specific and overall death were 3.2 (95% CI: 1.2 to 8.6) and 2.2 (95% CI: 1.1 to 4.4), respectively. On post-RC final pathology, 23 (46.9%) low-risk patients were up-classified to high risk and 17 (25.0%) high-risk patients were down-classified. Complete pathologic responses (pT0) were achieved in 7 (6.0%) patients and partial responses (pT1, pTa, pTis) were achieved in 28 (23.9%) patients. Of the 49 patients who did receive NAC, 43 (87.8%) received cisplatin-based and six (12.2%) received carboplatin-based regimens. Applying the MDACC model, we categorized 41 (83.7%) patients as high risk prior to NAC treatment. On final pathology, 3 (37.5%) low-risk patients were up-classified and 17 (41.5%) high-risk patients were down-classified. Complete pathologic responses (pT0) were seen in 13 (26.5%) patients and partial responses were seen in 10 (20.4%) patients. Although the utilization of NAC was not statistically significantly associated with CSS or OS (log-rank test p > 0.05 for both comparisons), it was associated with a 1.2 times increased odds (95% CI: 0.4 to 2.1) of post-RC reclassification from high to low risk on age-adjusted logistic regression. Conclusions: We found similar results using the clinical risk-stratification model in our cohort and showed that the high-risk category was associated with lower CSS and OS. NAC was associated with a higher probability of risk reclassification from high to low risk.

Abstract
CONTEXT In bladder cancer (BCa) patients, accurate local and regional tumor staging is required when planning treatment. Clinical understaging frequently occurs and leads to undertreatment of the disease, with a negative impact on survival. An improvement in staging accuracy could be attained by advances in imaging. Magnetic resonance imaging (MRI) is currently the best imaging technique for locoregional staging for several malignancies because of its superior soft tissue contrast resolution with the advantage of avoiding exposure to ionizing radiation. Important improvements in MRI technology have led to the introduction of multiparametric MRI (mpMRI), which combines anatomic and functional evaluation. OBJECTIVE To review the fundamentals of mpMRI in BCa and to provide a contemporary overview of the available data on the role of this emerging imaging technology. EVIDENCE ACQUISITION A nonsystematic literature search using the Medline and Cochrane Library databases was performed up to March 2016. Additional articles were retrieved by cross-matching references of selected articles. Only articles reporting complete data with regard to image acquisition protocols, locoregional staging, monitoring response to therapy, and detection of locoregional recurrence after primary treatment in BCa patients were selected. EVIDENCE SYNTHESIS Standardization of acquisition and reporting protocols for bladder mpMRI is paramount. Combining anatomic and functional sequences improves the accuracy of local tumor staging compared with conventional imaging alone. Diffusion-weighted imaging may distinguish BCa type and grade. Functional sequences are capable of monitoring response to chemotherapy and radiation therapy. Diffusion-weighted imaging enhanced by lymphotropic nanoparticles showed high accuracy in pelvic lymph node staging compared with conventional cross-sectional imaging. CONCLUSIONS In BCa patients, mpMRI appears a promising tool for accurate locoregional staging, predicting tumor aggressiveness and monitoring response to therapy. Further large-scale studies are needed to confirm these findings. PATIENT SUMMARY Better imaging through improved technology will improve outcomes in bladder cancer patients. We reviewed the emerging use of multiparametric magnetic resonance imaging for staging and monitoring bladder cancer. Multiparametric magnetic resonance imaging appears more accurate than current methods for local and nodal staging and monitoring tumor response to treatment, but requires further investigation.

Abstract
PURPOSE Clinical staging in patients with muscle invasive bladder cancer misses up to 25% of lymph node metastasis. These patients are at high risk for disease recurrence and improved clinical staging is critical to guide management. MATERIALS AND METHODS Whole transcriptome expression profiles were generated in 199 patients who underwent radical cystectomy and extended pelvic lymph node dissection. The cohort was divided randomly into a discovery set of 133 patients and a validation set of 66. In the discovery set features were identified and modeled in a KNN51 (K-nearest neighbor classifier 51) to predict pathological lymph node metastases. Two previously described bladder cancer gene signatures, including RF15 (15-gene cancer recurrence signature) and LN20 (20-gene lymph node signature), were also modeled in the discovery set for comparison. The AUC and the OR were used to compare the performance of these signatures. RESULTS In the validation set KNN51 achieved an AUC of 0.82 (range 0.71-0.93) to predict lymph node positive cases. It significantly outperformed RF15 and LN20, which had an AUC of 0.62 (range 0.47-0.76) and 0.46 (range 0.32-0.60), respectively. Only KNN51 showed significant odds of predicting LN metastasis with an OR of 2.65 (range 1.68-4.67) for every 10% increase in score (p <0.001). RF15 and LN20 had a nonsignificant OR of 1.21 (range 0.97-1.54) and 1.39 (range 0.52-3.77), respectively. CONCLUSIONS The new KNN51 signature was superior to previously described gene signatures for predicting lymph node metastasis. If validated prospectively in transurethral resection of bladder tumor samples, KNN51 could be used to guide patients at high risk to early multimodal therapy.

Abstract
Bladder cancer is one of the most common malignancies worldwide and the stage pT1nonmuscle invasive bladder cancer (NMIBC) has a high probability of recurrence after initial diagnosis and treatment. However, risk factors predictive of repeated recurrence and progression of pT1 bladder tumors after primary relapse have not been uncovered. Thus, we conducted the retrospective study.A total of 418 patients who suffered initial recurrence after transurethral resection (TUR) of pT1 bladder tumor were selected for the analyses. Clinic information of the patients was retrieved from their medical records. Recurrence-free survival (RFS) and progression-free survival (PFS) were estimated using the Kaplan-Meier method. Univariate and multivariate analyses were performed using a Cox proportional hazards regression model. The probability of recurrence and progression by multivariate analyses was used as a surrogate marker to construct receiver operating curve (ROC).Results showed that variables including time to prior recurrence time, prior treatment, number of tumor, tumor size, tumor grade, and time of instillation after surgery were associated with the repeated recurrence of pT1 bladder tumor (P < 0.05). The variables including time to prior recurrence time, tumor size, tumor grade, carcinoma in situ (CIS), and time of instillation after surgery were associated with progression of pT1 bladder tumor (P < 0.05). In the present study, the multivariate model showed an area under ROC (AUC) value of 0.754 and 0.798 for tumor recurrence and progression, respectively, which was more effective in prediction than a single risk factor.In conclusion, we have identified several risk factors relevant to RFS and PFS for patients who have had a history of recurrence of pT1 bladder tumor after TUR. These predictive factors may help urologists to stratify patients into distinct risk groups of recurrence and progression, which probably contributes to the individualized treatment for patients.

Abstract
Objective The management of stage 1 and grade 3 (T1G3) bladder cancer continues to be controversial. Although the transurethral resection of bladder tumor (TURBT) followed by intravesical chemotherapy is a conservative strategy for treatment of T1G3 bladder cancer, a relatively high risk of tumor recurrence and progression remains regarding the therapy. This study aimed to compare the efficacy of intravenous chemotherapy combined with intravesical chemotherapy versus intravesical chemotherapy alone for T1G3 bladder cancer after TURBT surgery. Methods We retrospectively reviewed the cases of 457 patients who were newly diagnosed with T1G3 bladder urothelial carcinoma between January 2009 and March 2014. After TURBT, 281 patients received intravesical chemotherapy alone, whereas 176 patients underwent intravesical chemotherapy in combination with intravenous chemotherapy. Tumor recurrence and progression were monitored periodically by urine cytology and cystoscopy in follow-up. Recurrence-free survival and progression-free survival of the two chemotherapy strategies following TURBT were analyzed. Univariable and multivariable Cox hazards analyses were performed to predict the prognostic factors for tumor recurrence and progression. Results The tumor recurrence rate was 36.7% for patients who received intravesical chemotherapy alone after TURBT, compared with 19.9% for patients who received intravenous chemotherapy combined with intravesical chemotherapy after TURBT (P<0.001). The progression rate was 10.6% for patients who underwent intravesical chemotherapy alone and 2.3% for patients who underwent the combined chemotherapies (P=0.003). Kaplan–Meier curves showed significant differences in recurrence-free survival and progression-free survival between the two treatment strategies, with a log-rank P-value of <0.001 and 0.003, respectively. Multivariable analyses revealed that intravenous chemotherapy was the independent prognostic factor for tumor recurrence and progression in the cohort. Conclusion Intravenous chemotherapy combined with intravesical chemotherapy offers a better oncologic outcome than the intravesical chemotherapy alone for patients with T1G3 bladder urothelial carcinoma after TURBT, and it may be considered as a new therapy strategy for T1G3 bladder cancer.

Abstract
The aim of the present study was to investigate whether the expression levels of CC-chemokine receptor 7 (CCR7) combined with computed tomography (CT) was associated with lymph node metastasis in bladder transitional cell carcinoma (BTCC). For this purpose, 115 cases of BTCC were analyzed at the Department of Urology of Xiangya Hospital, Central South University (Changsha, China). Preoperative CT scans of abdomen and pelvis, immunohistochemistry of CCR7 expression in the tumor specimens and pathological findings for lymph node metastasis were assessed. In addition, the sensitivity, specificity and accuracy of CCR7 and CT for the diagnosis of lymph node metastasis in BTCC were evaluated separately and jointly. The expression levels of CCR7 were observed to be significantly higher in BTCC than in normal controls (P<0.01). Multivariate analysis indicated that the overexpression of CCR7 was an independent predictor for lymph node metastasis in BTCC (P<0.05). The sensitivity, specificity and accuracy of CCR7 combined with CT scan for the diagnosis of lymph node metastasis in BTCC were 92.3, 83.6 and 70.0%, respectively. By contrast, the sensitivity, specificity and accuracy of CCR7 alone were 88.1, 69.9 and 76.5%, respectively, while the sensitivity, specificity and accuracy of CT alone were 52.4, 79.5 and 69.6%, respectively. The results of the present study indicated that CCR7 is an independent predictor of lymph node metastasis in BTCC. Therefore, the use of CCR7 combined with CT may improve the accuracy of the diagnosis of lymph node metastasis in BTCC.

Abstract
Purpose To externally validate models to predict LN metastsis; Karakiewicz nomogram, clinical nodal staging score (cNSS), and pathologic nodal staging score (pNSS) using a different cohort Materials and Methods Clinicopathologic data from 500 patients who underwent radical cystectomy and pelvic lymphadenectomy were analyzed. The overall predictive values of models were compared with the criteria of overall performance, discrimination, calibration, and clinical usefulness. Results Presence of pN+ stages was recorded in 117 patients (23.4%). Agreement between clinical and pathologic stage was noted in 174 (34.8%). Based on Nagelkerke’s peudo-R2 and brier score, pNSS demonstrated best overall performance. Area under the receiver operating characteristics curve, showed that pNSS had the best discriminatory ability. In all models, calibration was on average correct (calibration-in-the-large coefficient = zero). On decision curve analysis, pNSS performed better than other models across a wide range of threshold probabilities. Conclusions When compared to pNSS, current precystectomy models such as the Karakiewicz nomogram and cNSS cannot predict the probability of LN metastases accurately. The findings suggest that the application of pNSS to Asian patients is feasible.

Abstract
PURPOSE OF REVIEW Radical cystectomy with or without systemic chemotherapy is considered a standard of care for patients with muscle invasive bladder cancer (MIBC). The purpose of this review is to provide an update on current and recent literature published within the last 12 months reviewing the evidence for use of perioperative chemotherapy for patients with MIBC. RECENT FINDINGS In the neoadjuvant chemotherapy (NAC) setting, the evidence demonstrates clinical efficacy and lower rate of toxicity with the use of high-dose methotrexate, vinblastine, doxorubicin, and cyclophosphamide (MVAC) compared with standard MVAC. Higher quality evidence for the use of gemcitabine with cisplatin is not yet available. Meta-analysis of cisplatin-based regimens in the adjuvant setting demonstrates significant benefit in overall survival and disease-free survival specifically in patients with lymph-node-positive disease. SUMMARY The available evidence suggests that along with radical cystectomy, cisplatin-based perioperative chemotherapy should be the standard of care in patients with MIBC with a higher quality and quantity of literature in support of the NAC approach. Adoption of perioperative chemotherapy for MIBC is on the rise in North America, which is reassuring. Novel therapeutic approaches for cisplatin-ineligible patients are currently being investigated.

Abstract
Adequately selecting a therapeutic approach for bladder cancer depends on accurate grading and staging. Substantial inaccuracy of clinical staging with bimanual examination, cystoscopy, and transurethral resection of bladder tumor has facilitated the increasing utility of magnetic resonance imaging to evaluate bladder cancer. Diffusion-weighted imaging (DWI) is a noninvasive functional magnetic resonance imaging technique. The high tissue contrast between cancers and surrounding tissues on DWI is derived from the difference of water molecules motion. DWI is potentially a useful tool for the detection, characterization, and staging of bladder cancers; it can also monitor posttreatment response and provide information on predicting tumor biophysical behaviors. Despite advancements in DWI techniques and the use of quantitative analysis to evaluate the apparent diffusion coefficient values, there are some inherent limitations in DWI interpretation related to relatively poor spatial resolution, lack of cancer specificity, and lack of standardized image acquisition protocols and data analysis procedures that restrict the application of DWI and reproducibility of apparent diffusion coefficient values. In addition, inadequate bladder distension, artifacts, thinness of bladder wall, cancerous mimickers of normal bladder wall and benign lesions, and variations in the manifestation of bladder cancer may interfere with diagnosis and monitoring of treatment. Recognition of these pitfalls and limitations can minimize their impact on image interpretation, and carefully applying the analyzed results and combining with pathologic grading and staging to clinical practice can contribute to the selection of an adequate treatment method to improve patient care.

Abstract
Background: The ability to accurately determine tumor stage in bladder cancer is critical because it impacts the management paradigm and overall prognosis. There is often discrepancy between clinical and pathologic staging. Historically, exam under anesthesia (EUA) has been recommended to assist in the staging of bladder cancer. Objective: In this era of modern imaging technology, we sought to determine if EUA still contributes meaningfully to the local staging of bladder cancer. Methods: We retrospectively reviewed the charts of 1898 patients from 1994–2013 in our radical cystectomy database at MD Anderson Cancer Center. There were 414 patients that had complete information including EUA and whose surgery was performed by one of two surgeons and included in the final analysis. Univariate and multiple logistic regression models were generated to determine the ability of EUA, imaging, and other patient characteristics to predict pathological fat extension at the time of cystectomy. Results:
38% of patients had≥pT3 disease at the time of cystectomy. 30.9% of patients had findings on EUA suggestive of T3 disease and 28.7% had radiologic findings suggestive of T3 disease. In a model including age, BMI, ethnicity, year of operation, and neoadjuvant chemotherapy among other factors, the only factors predictive of pT3 disease were EUA and imaging (p = 0.002). The combination of EUA and imaging improved the accuracy of clinical staging compared to either modality alone.
Conclusions: Despite modern advances in imaging, EUA contributes meaningfully to accurate determination of local bladder cancer stage.

Abstract
Radical cystectomy with lymphadenectomy is currently the standard of care for muscle-invasive urothelial bladder cancer; however and because of its morbidity and its impact on quality of life, there is a growing tendency for bladder-sparing strategies. Initially reserved for elderly or unfit patients unable to undergo radical cystectomy, chemoradiotherapy became a true alternative to surgery for highly selected patients. Although there are no randomized trials comparing radical cystectomy with bladder preserving approaches, surgery remains the preferred treatment for many clinicians. Furthermore, comparison is even more difficult as modalities of radiotherapy are not consensual and differ between centers with a variability of protocols, volume of irradiation and type of chemotherapy. Several ongoing trials are attempting to optimize chemoradiotherapy and limit its toxicity, especially through techniques of adaptive radiotherapy or targeted therapies.

Pre-treatment neutrophil-to-lymphocyte ratio as predictor of adverse outcomes in patients undergoing radical cystectomy for urothelial carcinoma of the bladder. Br J Cancer 2014; 111:444-51. [PMID: 24918819 PMCID: PMC4119979 DOI: 10.1038/bjc.2014.305] [Citation(s) in RCA: 88] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2014] [Revised: 04/18/2014] [Accepted: 05/12/2014] [Indexed: 01/04/2023] Open
Abstract
BACKGROUND An elevated neutrophil-to-lymphocyte ratio (NLR) is associated with poor outcome in various tumours. Its prognostic utility in patients with urothelial carcinoma of the bladder (UCB) undergoing radical cystectomy (RC) is yet to be fully elucidated. METHODS A cohort of patients undergoing RC for UCB in a tertiary referral centre between 1992 and 2012 was analysed. Neutrophil-to-lymphocyte ratio was computed using complete blood counts performed pre-RC, or before neo-adjuvant chemotherapy where applicable. Time-dependent receiver operating characteristic curves were used to determine the optimal cutoff point for predicting recurrence-free survival (RFS), cancer-specific survival (CSS) and overall survival (OS). The predictive ability of NLR was assessed using Kaplan-Meier analyses and multivariable Cox proportional hazards models. The likelihood-ratio test was used to determine whether multivariable models were improved by including NLR. RESULTS The cohort included 424 patients followed for a median of 58.4 months. An NLR of 3 was determined as the optimal cutoff value. Patients with an NLR⩾3.0 had significantly worse survival outcomes (5y-RFS: 53% vs 64%, log-rank P=0.013; 5y-CSS: 57% vs 75%, log-rank P<0.001; 5y-OS: 43% vs 64%, log-rank P<0.001). After adjusting for disease-specific predictors, an NLR ⩾3.0 was significantly associated with worse RFS (HR=1.49; 95% CI=1.12-2.0, P=0.007), CSS (HR=1.88; 95% CI=1.39-2.54, P<0.001) and OS (average HR=1.67; 95% CI=1.17-2.39, P=0.005). The likelihood-ratio test confirmed that prognostic models were improved by including NLR. CONCLUSIONS Neutrophil-to-lymphocyte ratio is an inexpensive prognostic biomarker for patients undergoing RC for UCB. It offers pre-treatment prognostic value in addition to established prognosticators and may be helpful in guiding treatment decisions.

Abstract
PURPOSE To examine the accuracy of clinical staging and its effects on outcome in bladder cancer (BC) patients treated with radical cystectomy (RC), using a large national database. METHODS AND MATERIALS A total of 16,953 patients with BC without distant metastases treated with RC from 1998 to 2009 were analyzed. Factors associated with clinical-pathologic stage discrepancy were assessed by multivariate generalized estimating equation models. Survival analysis was conducted for patients treated between 1998 and 2004 (n=7270) using the Kaplan-Meier method and Cox proportional hazards models. RESULTS At RC 41.9% of patients were upstaged, whereas 5.9% were downstaged. Upstaging was more common in females, the elderly, and in patients who underwent a more extensive lymphadenectomy. Downstaging was less common in patients treated at community centers, in the elderly, and in Hispanics. Receipt of preoperative chemotherapy was highly associated with downstaging. Five-year overall survival rates for patients with clinical stages 0, I, II, III, and IV were 67.2%, 62.9%, 50.4%, 36.9%, and 27.2%, respectively, whereas those for the same pathologic stages were 70.8%, 75.8%, 63.7%, 41.5%, and 24.7%, respectively. On multivariate analysis, upstaging was associated with increased 5-year mortality (hazard ratio [HR] 1.80, P<.001), but downstaging was not associated with survival (HR 0.88, P=.160). In contrast, more extensive lymphadenectomy was associated with decreased 5-year mortality (HR 0.76 for ≥10 lymph nodes examined, P<.001), as was treatment at an National Cancer Institute-designated cancer center (HR 0.90, P=.042). CONCLUSIONS Clinical-pathologic stage discrepancy in BC patients is remarkably common across the United States. These findings should be considered when selecting patients for preoperative or nonoperative management strategies and when comparing the outcomes of bladder sparing approaches to RC.

Abstract
PURPOSE OF REVIEW To provide an overview on the available clinical and pathological factors in high-risk nonmuscle invasive bladder cancer (NMIBC) patients that help to approximate the risk of progression to muscle invasion and identify 'the' patients requiring timely cystectomy. The value of a high-quality transurethral tumor resection is pointed out. Outcomes following radical cystectomy are compared with a primarily bladder preserving strategy. RECENT FINDINGS Carcinoma in situ within the prostatic urethra of NMIBC patients impacts on patient's outcome. Therefore, biopsies taken from the prostatic urethra improve the initial tumor staging accuracy. Lamina propria substaging may provide more detailed prognostic information. Lympho-vascular invasion within the transurethral resection specimen may help to detect patients who benefit from timely cystectomy. Recent findings from patients undergoing radical cystectomy including super-extended lymphadenectomy for clinically NMIBC confirm the substantial rate (25%) of tumor understaging. The fact that almost 10% were found to harbor lymph node metastases underlines the necessity to perform a meticulous lymphadenectomy in NMIBC patients undergoing radical cystectomy. SUMMARY High-quality transurethral bladder tumor resection including underlying muscle fibers is of utmost importance. Nevertheless, tumor understaging remains an issue of concern and warrants the value of a second transurethral resection in high-risk NMIBC patients. There is a persisting lack of rigid therapeutic recommendations in patients with high-risk NMIBC. Instead, treatment strategy is based on individual risk factors. However, irrespective of initial treatment strategy, there is a subgroup of high-risk NMIBC patients with progressive disease, leading almost inevitably to death.

Abstract
En bloc removal of the prostate has traditionally been an integral component of radical cystectomy for men with bladder cancer owing to a high incidence of occult prostatic malignancy. However, the risk of functional morbidity following this procedure is considerable and can delay patient acceptance of cystectomy, which can adversely affect the long-term prognosis. Recently, some investigators have advocated prostate-sparing cystectomy (PSCx) to improve postoperative continence and potency rates, and this may also improve timely patient acceptance of cystectomy. Several of these PSCx series describe excellent functional results postoperatively and PSCx may also facilitate a laparoscopic approach, offering further dividends. However, valid concerns regarding the oncologic efficacy of this procedure still predominate and protocols for patient selection, technique and postoperative surveillance are not well defined. The concept of PSCx is arguably one of the most controversial topics in the field of bladder cancer today.

Abstract
PURPOSE To evaluate the impact of concomitant carcinoma in situ (CIS) on upstaging and outcome of patients treated with radical cystectomy with pelvic lymph node dissection. METHODS We collected and pooled a database of 1,968 patients who have undergone radical cystectomy between 1998 and 2008 in eight academic centers across Canada. Collected variables included patient's age, gender, tumor grade, histology and the presence of concomitant CIS with either cTa-1 or cT2 disease, dates of recurrence and death. RESULTS In the presence of concomitant CIS, upstaging following radical cystectomy occurred in 48 and 55 % of patients with cTa-1 and cT2 disease, respectively. On univariate analysis, the presence of concomitant CIS with cT2 disease was associated with upstaging (p < 0.0001), and the presence of concomitant CIS with cTa-1 disease was also associated with upstaging but did not reach statistical significance (p = 0.0526). On multivariate analyses, the presence of concomitant CIS with either cTa-1 or cT2 tumors was independently prognostic of disease upstaging (p = 0.0001 and 0.0186, respectively). However, on multivariate analysis that incorporates pathologic stage, concomitant CIS was not significantly associated with worse overall, recurrence-free or disease-specific survival. CONCLUSION These results demonstrate that while the presence of concomitant CIS on cystectomy specimens does not independently affect outcomes, its presence is significantly predictive of a higher rate of upstaging at radical cystectomy.
