Pre-Op Hydronephrosis Predicts Outcomes in Patients Receiving Robot-Assisted Radical Cystectomy. Cancers (Basel) 2024; 16:2826. [PMID: 39199597 PMCID: PMC11353176 DOI: 10.3390/cancers16162826] [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: 07/11/2024] [Revised: 07/30/2024] [Accepted: 08/07/2024] [Indexed: 09/01/2024] Open
Abstract
INTRODUCTION Robot-assisted radical cystectomy (RARC) has gained momentum in the management of muscle invasive bladder cancer (MIBC). Predictors of RARC outcomes are not thoroughly studied. We aim to investigate the implications of preoperative hydronephrosis on oncological outcomes. PATIENTS AND METHODS This study analysed data from the Asian RARC consortium, a multicentre registry involving nine Asian centres. Cases were divided into two groups according to the presence or absence of pre-operative hydronephrosis. Background characteristics, operative details, perioperative outcomes, and oncological results were reviewed. Outcomes were (1) survival outcomes, including 10-year disease-free survival (DFS) and overall survival (OS), and (2) perioperative and pathological results. Multivariate regression analyses were performed on survival outcomes. RESULTS From 2007 to 2020, 536 non-metastatic MIBC patients receiving RARC were analysed. 429 had no hydronephrosis (80.0%), and 107 (20.0%) had hydronephrosis. Hydronephrosis was found to be predictive of inferior DFS (HR = 1.701, p = 0.003, 95% CI = 1.196-2.418) and OS (HR = 1.834, p = 0.008, 95% CI = 1.173-2.866). Subgroup analysis demonstrated differences in the T2-or-above subgroup (HR = 1.65; p = 0.004 in DFS and HR = 1.888; p = 0.008 in OS) and the T3-or-above subgroup (HR = 1.757; p = 0.017 in DFS and HR = 1.807; p = 0.034 in OS). CONCLUSIONS The presence of preoperative hydronephrosis among MIBC patients carries additional prognostic implications on top of tumour staging. Its importance in case selection needs to be highlighted.

The Impact of Variant Histology in Patients with Urothelial Carcinoma Treated with Radical Cystectomy: Can We Predict the Presence of Variant Histology? Curr Oncol 2023; 30:8841-8852. [PMID: 37887538 PMCID: PMC10605515 DOI: 10.3390/curroncol30100638] [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: 08/12/2023] [Revised: 09/17/2023] [Accepted: 09/20/2023] [Indexed: 10/28/2023] Open
Abstract
Considering the divergent biological behaviors of certain histological subtypes of urothelial carcinoma, it would be of great importance to examine the impact of variant histology and to predict its presence in patients with bladder cancer. A single-center cohort study included 459 patients who underwent radical cystectomy for urothelial carcinoma between 2017 and 2021. Patients were followed up with until July 2022. We compared clinical, laboratory, and histopathologic characteristics and the overall survival between patients with pure urothelial carcinoma and variant histologies. Our results showed that the patients with variant histology were older and preoperatively more frequently had hydronephrosis and higher values of leukocytes and neutrophils. Also, we found a significant association between variant histology and an advanced stage of tumor disease, the presence of lymphovascular invasion, positive surgical margins, and metastases in surgically resected lymph nodes. The number of neutrophils was identified as an independent preoperative predictor of the presence of variant histology after a radical cystectomy. The overall survival of the patients with variant histology was significantly lower compared to the patients with pure urothelial carcinoma. According to our results, the presence of variant histology represents a more aggressive form of the disease. Preoperative neutrophil counts may indicate the presence of variant histology of urothelial carcinoma in patients with bladder cancer.

New Hydronephrosis in the Native Kidney Is Associated with the Development of De Novo Urinary Bladder Urothelial Carcinoma in Patients with Post-Kidney Transplantation. Healthcare (Basel) 2023; 11:healthcare11091209. [PMID: 37174750 PMCID: PMC10178461 DOI: 10.3390/healthcare11091209] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Revised: 04/18/2023] [Accepted: 04/20/2023] [Indexed: 05/15/2023] Open
Abstract
Increased malignancy after kidney transplantation (KT) is by far the most troublesome issue. Among these malignancies, urothelial carcinoma (UC) incidence is uniquely high in Taiwan. We want to know whether routine sonography to detect native hydronephrosis is associated with the development of de novo urinary bladder urothelial carcinoma (UBUC) in post-KT recipients. From 2003 to 2018, we retrospectively analyzed 1005 KT patients, 58 of whom were subsequently diagnosed with UBUC. The association between new native hydronephrosis and post-KT UBUC was analyzed with univariate and multivariate logistic regression analyses and a Kaplan-Meier plot. We excluded cases of people who had upper urinary tract urothelial carcinoma (UTUC) and were diagnosed prior to UBUC. There were 612 males (60.9%) and 393 females (39.1%), with a mean age of 48.2 ± 12.0 years old at KT. The mean follow-up period was 118.6 ± 70.2 months, and the diagnosis of UBUC from KT to UBUC was 7.0 ± 5.1 years. New native kidney hydronephrosis occurred more frequently in the UBUC group (56.4% versus 6.4%, p < 0.001) than the non-UBUC group. Multivariate analysis disclosed that native hydronephrosis is the only statistically significant factor for UBUC, with an odds ratio of 16.03 (95% CI, 8.66-29.68; p < 0.001). UBUC in post-KT patients with native hydronephrosis also showed a tendency toward multifocal lesions upon presentation (47.8%). Post-KT UBUC is characterized by pathologically aggressive and multiple foci lesions. Native kidney hydronephrosis may be a deciding factor of post-KT UBUC.

The Value of Preoperative Local Symptoms in Prognosis of Upper Tract Urothelial Carcinoma After Radical Nephroureterectomy: A Retrospective, Multicenter Cohort Study. Front Oncol 2022; 12:872849. [PMID: 35719933 PMCID: PMC9201473 DOI: 10.3389/fonc.2022.872849] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Accepted: 05/09/2022] [Indexed: 11/13/2022] Open
Abstract
Purpose We aimed to evaluate the impact of preoperative local symptoms on prognosis after radical nephroureterectomy in patients with upper tract urothelial carcinoma (UTUC). Methods This retrospective study consisted of 2,662 UTUC patients treated at 15 institutions in Taiwan from 1988 to 2019. Clinicopathological data were retrospectively collected for analysis by the Taiwan UTUC Collaboration Group. The Kaplan-Meier method was used to calculate overall survival (OS), cancer-specific survival (CSS), disease-free survival (DFS), and bladder recurrence-free survival (BRFS). The prognostic value of preoperative local symptoms in OS, CSS, DFS, and BRFS was investigated using Cox proportional hazards models. Results The median follow-up was 36.6 months. Among 2,662 patients, 2,130 (80.0%) presented with hematuria and 398 (15.0%) had symptomatic hydronephrosis at diagnosis. Hematuria was associated with less symptomatic hydronephrosis (p <0.001), more dialysis status (p = 0.027), renal pelvic tumors (p <0.001), and early pathological tumor stage (p = 0.001). Symptomatic hydronephrosis was associated with female patients (p <0.001), less dialysis status (p = 0.001), less bladder cancer history (p <0.001), ureteral tumors (p <0.001), open surgery (p = 0.006), advanced pathological tumor stage (p <0.001), and postoperative chemotherapy (p = 0.029). Kaplan-Meier analysis showed that patients with hematuria or without symptomatic hydronephrosis had significantly higher rates of OS, CSS, and DFS (all p <0.001). Multivariate analysis confirmed that presence of hematuria was independently associated with better OS (HR 0.789, 95% CI 0.661-0.942) and CSS (HR 0.772, 95% CI 0.607-0.980), while symptomatic hydronephrosis was a significant prognostic factor for poorer OS (HR 1.387, 95% CI 1.142-1.683), CSS (HR 1.587, 95% CI 1.229-2.050), and DFS (HR 1.378, 95% CI 1.122-1.693). Conclusions Preoperative local symptoms were significantly associated with oncological outcomes, whereas symptomatic hydronephrosis and hematuria had opposite prognostic effects. Preoperative symptoms may provide additional information on risk stratification and perioperative treatment selection for patients with UTUC.

Abstract
PURPOSE Epidemiological studies reported conflicting results about preoperative hydronephrosis in upper tract urothelial carcinoma (UTUC). This study aimed to investigate the association between preoperative hydronephrosis and pathologic features and oncologic outcomes in patients with UTUC treated by radical nephroureterectomy (RNU). MATERIALS AND METHODS This was a retrospective, single-center cohort study of 377 patients treated by RNU without perioperative chemotherapy between January 2001 and December 2014. Logistic regression, Cox regression, and survival analyses were performed. RESULTS Among the 226 patients with high-grade UTUC, 132 (58%) had preoperative hydronephrosis. Multivariable logistic regression revealed that hydronephrosis was independently associated with advanced pT stage (P=0.017) and lymph node or lymphovascular invasion (P=0.002). Median follow-up was 36 months (interquartile range: 20-48 months). The 3- and 5-year overall survival (OS) rates in patients with hydronephrosis were significantly lower than in those without hydronephrosis (both P <0.001). The 3- and 5-year cancer-specific survival (CSS) rates in patients with hydronephrosis were significantly lower than in those without hydronephrosis (both P=0.001). Hydronephrosis was independently associated with OS and CSS (P=0.001 and P=0.004, respectively). Among the 151 patients with low-grade UTUC, hydronephrosis was not associated with pathologic features and postoperative survival. CONCLUSIONS Preoperative hydronephrosis was significantly associated with adverse pathologic features and postoperative survival in patients with high-grade UTUC.

Abstract
OPINION STATEMENT Although radical cystectomy is considered the gold standard approach for patients with muscle-invasive bladder cancer, tri-modal therapy (TMT) is a well-tolerated and efficacious alternative to radical cystectomy that is underutilized in inoperable patients and rarely offered to cystectomy candidates in the USA. Retrospective data suggest similar outcomes between radical cystectomy and TMT after adjusting for patient selection and other confounding factors. Nearly 70-80% of patients can keep their native bladder with favorable post-treatment quality of life metrics. Current trials are investigating novel combination strategies including immune checkpoint inhibition along with chemoradiation or radiation. Emerging techniques for improved patient selection and risk stratification include incorporating MP-MRI, and novel biomarkers such as inflammatory, stromal, and DNA damage response gene signatures may guide patient selection and expand the landscape of bladder preservation options available to patients in the future.

Prediction of the Need for an Extended Lymphadenectomy at the Time of Radical Cystectomy in Patients with Bladder Cancer. Eur Urol Focus 2020; 7:1067-1074. [PMID: 33020030 DOI: 10.1016/j.euf.2020.09.009] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2020] [Revised: 09/07/2020] [Accepted: 09/18/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND A prospective randomized trial (LEA AUO AB 25/02) found no survival benefit in extended compared with limited pelvic lymph node dissection (PLND) templates in bladder cancer (BCa) patients treated with radical cystectomy (RC). However, the rate of lymph node invasion (LNI) in the standard and extended templates was lower than estimated. OBJECTIVE To assess the accuracy of preoperative clinical and pathological parameters to predict LNI and to develop a model to preoperatively select candidates for the extended PLND templates. DESIGN, SETTING, AND PARTICIPANTS A total of 903 BCa patients treated at a single institution were retrospectively identified. The primary outcome was to identify preoperatively the risk of LNI to tailor the type of PLND. The extended PLND templates consisted in the removal of pelvic lymph nodes together with the common iliac, presacral, para-aortocaval, interaortocaval, and paracaval sites up to the inferior mesenteric artery. INTERVENTION A total of 903 BCa patients were treated with RC and bilateral extended PLND templates. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Several models predicting LNI were evaluated using the area under the receiver operating characteristic curve (AUC), calibration plots and decision curve analyses. A nomogram predicting LNI in the extended pattern was developed and validated internally. RESULTS AND LIMITATIONS Overall, 55 patients (6.1%) had LNI in the extended PLND templates at RC. The median number of nodes removed was 19 (interquartile range: 13-26). A model including age, clinical T stage, clinical node stage, lymphovascular invasion, and presence of carcinoma in situ at the last transurethral resection before RC was developed. The AUC of this model is 73%. Using a cutoff of 3%, 108 extended PLNDs (12%) would be spared and only two LNIs (3%) would be missed. The main limitations of our model are the retrospective nature of the data, lack of external validation, and low rate of LNI. CONCLUSIONS This is the first proposed model to predict LNI in the extended PLND templates. This model might help urologists identify which patients might benefit from an extended PLND at the time of RC, reserving a standard PLND for all the others. PATIENT SUMMARY We developed the first nomogram to predict lymph node invasion (LNI) in the extended pelvic lymph node dissection templates in bladder cancer patients treated with radical cystectomy. The adoption of our model to identify candidates for the extended pelvic lymph node dissection templates could avoid up to 12% of these procedures at the cost of missing only 3% of patients with LNI.

Can preoperative imaging characteristics predict pT3 bladder cancer following cystectomy? World J Urol 2020; 39:1941-1945. [PMID: 32725305 DOI: 10.1007/s00345-020-03375-w] [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: 05/27/2020] [Accepted: 07/18/2020] [Indexed: 10/23/2022] Open
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.

Association of chromosome 7 aneuploidy measured by fluorescence in situ hybridization assay with muscular invasion in bladder cancer. Cancer Commun (Lond) 2020; 40:167-180. [PMID: 32279463 PMCID: PMC7170658 DOI: 10.1002/cac2.12017] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2019] [Revised: 02/27/2020] [Accepted: 03/02/2020] [Indexed: 12/29/2022] Open
Abstract
Background The preoperative prediction of muscular invasion status is important for adequately treating bladder cancer (BC) but nevertheless, there are some existing dilemmas in the current preoperative diagnostic accuracy of BC with muscular invasion. Here, we investigated the potential association between the fluorescence in situ hybridization (FISH) assay and muscular invasion among patients with BC. A cytogenetic‐clinical nomogram for the individualized preoperative differentiation of muscle‐invasive BC (MIBC) from non‐muscle‐invasive BC (NMIBC) is also proposed. Methods All eligible BC patients were preoperatively tested using a FISH assay, which included 4 sites (chromosome‐specific centromeric probe [CSP] 3, 7, and 17, and gene locus‐specific probe [GLP]‐p16 locus). The correlation between the FISH assay and BC muscular invasion was evaluated using the Chi‐square tests. In the training set, univariate and multivariate logistic regression analyses were used to develop a cytogenetic‐clinical nomogram for preoperative muscular invasion prediction. Then, we assessed the performance of the nomogram in the training set with respect to its discriminatory accuracy and calibration for predicting muscular invasion, and clinical usefulness, which were then validated in the validation set. Moreover, model comparison was set to evaluate the discrimination and clinical usefulness between the nomogram and the individual variables incorporated in the nomogram. Results Muscular invasion was more prevalent in BC patients with positive CSP3, CSP7 and CSP17 status (OR [95% CI], 2.724 [1.555 to 4.774], P < 0.001; 3.406 [1.912 to 6.068], P < 0.001 and 2.483 [1.436 to 4.292], P = 0.001, respectively). Radiology‐determined tumor size, radiology‐determined clinical tumor stage and CSP7 status were identified as independent risk factors of BC muscular invasion by the multivariate regression analysis in the training set. Then, a cytogenetic‐clinical nomogram incorporating these three independent risk factors was constructed and was observed to have satisfactory discrimination in the training (AUC 0.784; 95% CI: 0.715 to 0.853) and validation (AUC 0.743; 95% CI: 0.635 to 0.850) set. The decision curve analysis (DCA) indicated the clinical usefulness of our nomogram. In models comparison, using the receiver operator characteristic (ROC) analyses, the nomogram showed higher discriminatory accuracy than any variables incorporated in the nomogram alone and the DCAs also identified the nomogram as possessing the highest net benefits at wide range of threshold probabilities. Conclusion CSP7 status was identified as an independent factor for predicting muscular invasion in BC patients and was successfully incorporated in a clinical nomogram combining the results of the FISH assay with clinical risk factors.

Prognostic value of preoperative hydronephrosis in patients with bladder cancer undergoing radical cystectomy: A meta-analysis. PLoS One 2019; 14:e0222223. [PMID: 31513614 PMCID: PMC6742405 DOI: 10.1371/journal.pone.0222223] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2019] [Accepted: 08/23/2019] [Indexed: 12/23/2022] Open
Abstract
Background Hydronephrosis is a common finding in patients with bladder cancer. The aim of the study was to appraise the prognostic value of preoperative hydronephrosis in bladder cancer patients undergoing radical cystectomy. Methods We conducted a literature search using PubMed and Embase databases in Aug 2018. Summary hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated using fixed-effect or random-effects models. The primary endpoint was overall survival (OS). Secondary endpoints were cancer-specific survival (CSS) and recurrence-free survival (RFS). Results Overall, 13 studies published between 2008 and 2018 including 4,820 patients were selected for the meta-analysis. The age of bladder cancer patients ranged from 27 to 90.4 years, and the overall proportion of males was 72.5%. Preoperative hydronephrosis was reported in 27.4% of patients. The pooled HR was statistically significant for OS (HR, 1.36; 95% CI [1.20–1.55]) and CSS (HR, 1.64; 95% CI [1.33–2.02]), with no heterogeneity among the enrolled studies. Patients with bilateral hydronephrosis showed a poorer CSS compared to those with no hydronephrosis (HR 5.43, 95% CI [3.14–9.40]). However, there was no difference in CSS between no hydronephrosis and unilateral hydronephrosis groups (HR 1.35, 95% CI [0.84–2.14]). Despite a tendency towards poorer RFS (HR, 1.27; 95% CI [0.96–1.96]), the results demonstrated no significant association between presence of preoperative hydronephrosis and RFS after radical cystectomy. Conclusion This meta-analysis indicates that preoperative hydronephrosis is significantly associated with poorer OS and CSS after radical cystectomy for patients with bladder cancer. Preoperative hydronephrosis has a stronger effect on CSS in patients with bilateral hydronephrosis. The presence of preoperative hydronephrosis not only predicts prognosis, but may also help to identify patients who benefit the most from neoadjuvant chemotherapy.

Molecular subtypes applied to a population-based modern cystectomy series do not predict cancer-specific survival. Urol Oncol 2019; 37:791-799.

Abstract
OBJECTIVES To investigate the preoperative prognostic value of molecular subtypes in relation to clinical information, histopathological findings, and molecular markers for patients with bladder cancer treated with radical cystectomy. PATIENTS AND METHODS After standard preoperative staging, a population-based cohort of 519 patients underwent radical cystectomy between 2006 and 2011. Following pathological review of all transurethral resection of bladder tumor specimens, tissue microarrays were constructed, and RNA was extracted from formalin-fixed tissue blocks. Immunohistochemistry (IHC) was performed using markers suggested to be relevant for prognosis (ZEB2, CCND1, CD3, CD68, CDH3, HER3, KRT14, CDKN2A(p16), TP63, FGFR3, EPCAM, GATA3, FOXA1, ERBB2, and EGFR). IHC- and gene-expression-based molecular classification was also conducted. Univariate and multivariate Cox proportional hazards regression were used for survival analyses. RESULTS Clinical T3 stage (Hazard Ratio [HR] 1.6, Confidence Interval [CI] 1.1-2.3), hydronephrosis (HR 1.7, CI 1.2-2.3), lymphovascular invasion (LVI) (HR 2.6, CI 1.9-3.6), extensive necrosis (HR 1.6, CI 1.1-2.5), and CD68/CD3-ratio >1 (HR 1.3, CI 1.1-1.5) in the transurethral resection of bladder tumor specimen was associated with worse cancer-specific survival (CSS) and progression-free survival (data not shown). In multivariate analysis, higher clinical T stage (HR 1.3, CI 1.1-1.7; P = 0.007) and presence of LVI (HR 2.4, CI 1.7-3.5; P = 1.8 × 10-6) were associated with worse CSS, whereas only LVI was associated with progression-free survival. Molecular subtypes (assessed by Lund taxonomy and the Consensus molecular subtypes of muscle-invasive bladder cancer) and published single IHC markers were not associated with survival. CONCLUSIONS In the present large population-based cystectomy series, LVI and clinical stage were independently associated with CSS. However, molecular subtypes determined by global gene expression showed no such association with CSS according to either the Consensus molecular subtypes of muscle-invasive bladder cancer or Lund taxonomy.

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
Background: Preoperative hydronephrosis (HN) might be associated with adverse outcomes in patients who underwent radical cystectomy (RC). The aim of this study was to evaluate the effect of preoperative HN on the oncological outcomes in patients with bladder cancer who underwent RC by performing a systemic review and meta-analysis. Methods: A systematic literature review in PubMed, EMBASE, and Scopus was conducted by searching the terms “bladder cancer,” “cystectomy,” and “hydronephrosis” until December 2016, in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines. The calculated end points were advanced disease stage, cancer-specific survival (CSS), and overall survival (OS). Results: Twenty-four studies involving 10,461 patients who underwent RC were included. Among the patients, 3,121 (29.8%) had preoperative HN. The pooled analysis showed that preoperative HN had a significant association with advanced stage (odds ratio, 2.56, 95% confidence interval [CI], 1.91–3.42, p < 0.00001), lymph node invasion (OR, 2.44, 95% CI, 1.79–3.34, p < 0.00001), CSS (hazard ratio [HR], 1.67, 95% CI, 1.34–2.08, p < 0.00001), and OS (HR, 1.51, 95% CI, 1.30–1.75, p < 0.00001). Conclusions: Among patients with bladder cancer who underwent RC, preoperative HN could be a significant predictor of bladder cancer survival. However, large well-designed prospective studies are required to confirm the precise prognostic significance of preoperative HN.

Abstract
PURPOSE We report the outcomes in patients with muscle invasive bladder cancer from 2 institutions who experienced a clinically complete response to neoadjuvant platinum based chemotherapy and elected active surveillance. It was unknown whether conservative treatment could be safely implemented in these patients. MATERIALS AND METHODS We retrospectively reviewed the records of patients with muscle invasive bladder cancer at our institutions who elected surveillance following a clinically complete response to transurethral resection of bladder tumors and neoadjuvant chemotherapy from 2001 to 2017. A clinically complete response was defined as absent tumor on post-chemotherapy transurethral resection of bladder tumor, negative cytology and normal cross-sectional imaging. RESULTS In the 148 patients followed a median of 55 months (range 5 to 145) the 5-year disease specific, overall, cystectomy-free and recurrence-free survival rates were 90%, 86%, 76% and 64%, respectively. Of the patients 71 (48%) experienced recurrence in the bladder, including 16 (11%) with muscle invasive disease and 55 (37%) with noninvasive disease. Salvage radical cystectomy prevented cancer specific death in 9 of 12 patients (75%) who underwent cystectomy after muscle invasive relapse and in 13 of 14 (93%) after noninvasive relapse. CONCLUSIONS We observed high rates of overall and disease specific survival with bladder preservation in patients who achieved a clinically complete response to neoadjuvant chemotherapy. These outcomes support the safety of active surveillance in carefully selected, closely monitored patients with muscle invasive bladder cancer. Future studies should aim to improve patient selection by identifying biomarkers predicting invasive relapse and developing novel imaging methods of early detection.

Abstract
BACKGROUND Although radical cystectomy (RC) is considered the gold standard treatment of muscle invasive bladder cancer, nearly half of patients develop metastases and ultimately die within 2 years. OBJECTIVE To assess survival, evaluate different prognostic factors that may affect disease-free survival (DFS) in Saudi patients after RC for carcinoma of the bladder and to compare our results with those of Western countries. DESIGN Retrospective chart review. SETTING A tertiary care center in Saudi Arabia. PATIENTS AND METHODS We collected data on patients who underwent RC for bladder cancer in the period between 1979 and 2014. Demographic, clinical and pathological variables and the application of perioperative chemotherapy were reviewed. Univariate and multivariate analyses were done with DFS as the end point. MAIN OUTCOME MEASURE Disease-specific survival. RESULTS On 328 patients for whom data was available, the median follow up was 23 months (range, 2 month-28 years) and median age was 58 years (range, 21-90). Of these patients, 268 were males (81.7%), 235 (71.7%) had urothelial carcinoma (UC), 79 (24.1%) had squamous cell carcinoma (SCC), and 208 (63.4%) had pathological tumor stage 3 or more. The 5-year overall survival (OS) and DFS were 52% and 48%, respectively. There was no statistically significant difference in DFS of patients with UC and pure SCC. On univariate analysis, lymph node status and pathological tumor stage were significant predictors of DFS. Both variables sustained statistical significance in a multivariate analysis. CONCLUSION Survival following RC is almost the same as others. Moreover, pathological tumor stage and lymph node metastasis were the only independent predictors for survival following RC. Future cooperative prospective studies are required to gain data on our region. LIMITATIONS Relatively small sample size and retrospective.

Abstract
Bladder cancer is the ninth most common cancer in the world. Twenty to twenty-five percent of all newly diagnosed bladder cancers are muscle invasive in nature, and further, 20-25% of patients who are diagnosed with high-risk non-muscle invasive disease will eventually progress to muscle invasive disease in due course of time irrespective of adjuvant intravesical therapies. Availability of newer imaging modalities improves appropriate identification of patients with muscle invasive disease. Radical cystectomy remains the mainstay of treatment for management of muscle invasive disease. Availability of neoadjuvant chemotherapy has improved overall survival. Risk stratification systems are now in consideration to identify patients who benefit maximally from neoadjuvant chemotherapy. Urinary diversion is a major cause of morbidity in these patients, and several strategies are being employed to reduce morbidity. In this article, we review available literature on various aspects of management of muscle invasive disease.

Concurrent Preoperative Presence of Hydronephrosis and Flank Pain Independently Predicts Worse Outcome of Upper Tract Urothelial Carcinoma. PLoS One 2015; 10:e0139624. [PMID: 26469704 PMCID: PMC4607422 DOI: 10.1371/journal.pone.0139624] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2015] [Accepted: 09/14/2015] [Indexed: 12/27/2022] Open
Abstract
Objectives To investigate the impact of preoperative hydronephrosis and flank pain on prognosis of patients with upper tract urothelial carcinoma. Methods In total, 472 patients with upper tract urothelial carcinoma managed by radical nephroureterectomy were included from Kaohsiung Medical University Hospital Healthcare System. Clinicopathological data were collected retrospectively for analysis. The significance of hydronephrosis, especially when combined with flank pain, and other relevant factors on overall and cancer-specific survival were evaluated. Results Of the 472 patients, 292 (62%) had preoperative hydronephrosis and 121 (26%) presented with flank pain. Preoperative hydronephrosis was significantly associated with age, hematuria, flank pain, tumor location, and pathological tumor stage. Concurrent presence of hydronephrosis and flank pain was a significant predictor of non-organ-confined disease (multivariate-adjusted hazard ratio = 2.10, P = 0.025). Kaplan-Meier analysis showed significantly poorer overall and cancer-specific survival in patients with preoperative hydronephrosis (P = 0.005 and P = 0.026, respectively) and in patients with flank pain (P< 0.001 and P = 0.001, respectively) than those without. However, only simultaneous hydronephrosis and flank pain independently predicted adverse outcome (hazard ratio = 1.98, P= 0.016 for overall survival and hazard ratio = 1.87, P = 0.036 for and cancer-specific survival, respectively) in multivariate Cox proportional hazards models. In addition, concurrent presence of hydronephrosis and flank pain was also significantly predictive of worse survival in patient with high grade or muscle-invasive disease. Notably, there was no difference in survival between patients with hydronephrosis but devoid of flank pain and those without hydronephrosis. Conclusion Concurrent preoperative presence of hydronephrosis and flank pain predicted non-organ-confined status of upper tract urothelial carcinoma. When accompanied with flank pain, hydronephrosis represented an independent predictor for worse outcome in patients with upper tract urothelial carcinoma.

Abstract
Introduction: We aimed at developing and validating a pre-cystectomy nomogram for the prediction of locally advanced urothelial carcinoma of the bladder (UCB) using clinicopathological parameters. Materials and Methods: Multicenter data from 337 patients who underwent radical cystectomy (RC) for UCB were prospectively collected and eligible for final analysis. Univariate and multivariate logistic regression models were applied to identify significant predictors of locally advanced tumor stage (pT3/4 and/or pN+) at RC. Internal validation was performed by bootstrapping. The decision curve analysis (DCA) was done to evaluate the clinical value. Results: The distribution of tumor stages pT3/4, pN+ and pT3/4 and/or pN+ at RC was 44.2, 27.6 and 50.4%, respectively. Age (odds ratio (OR) 0.980; p < 0.001), advanced clinical tumor stage (cT3 vs. cTa, cTis, cT1; OR 3.367; p < 0.001), presence of hydronephrosis (OR 1.844; p = 0.043) and advanced tumor stage T3 and/or N+ at CT imaging (OR 4.378; p < 0.001) were independent predictors for pT3/4 and/or pN+ tumor stage. The predictive accuracy of our nomogram for pT3/4 and/or pN+ at RC was 77.5%. DCA for predicting pT3/4 and/or pN+ at RC showed a clinical net benefit across all probability thresholds. Conclusion: We developed a nomogram for the prediction of locally advanced tumor stage pT3/4 and/or pN+ before RC using established clinicopathological parameters.

Degree of hydronephrosis predicts adverse pathological features and worse oncologic outcomes in patients with high-grade urothelial carcinoma of the upper urinary tract. Urol Oncol 2014; 32:981-8. [PMID: 25022858 DOI: 10.1016/j.urolonc.2014.02.018] [Citation(s) in RCA: 35] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2014] [Revised: 02/24/2014] [Accepted: 02/24/2014] [Indexed: 12/25/2022]
Abstract
OBJECTIVE To evaluate degree of hydronephrosis (HN) as a surrogate for adverse pathological features and oncologic outcomes in patients with high-grade (HG) and low-grade (LG) upper tract urothelial carcinomas (UTUCs). METHODS We retrospectively reviewed 141 patients with localized UTUCs that underwent extirpative surgery at a tertiary referral center. Preoperative imaging was used to evaluate presence and degree of ipsilateral HN. We evaluated degree of HN (none/mild vs. moderate/severe), pathological findings, and oncologic outcomes. RESULTS HG UTUC was present in 113 (80%) patients, muscle-invasive disease (≥pT2) in 49 (35%), and non-organ-confined disease (≥pT3) in 41 (29%). At a median follow-up of 34 months, 49 (35%) patients experienced intravesical recurrence, 28 (20%) developed local/systemic recurrence, and 24 (17%) died of UTUC. HN was graded as none/mild in 77 (55%) patients and moderate/severe in 64 (45%). In patients with HG UTUC, but not LG, degree of HN was associated with advanced pathological stage (P<0.001), positive lymph nodes (P = 0.01), local/systemic recurrence-free survival (hazard ratio [HR] = 5.5, P = 0.02), and cancer-specific survival (HR = 5.2, P = 0.02). On multivariable analysis of preoperative factors, degree of HN in patients with HG UTUC was associated with muscle invasion (HR = 9.3; 95% CI: 3.08-28.32; P<0.001), non-organ-confined disease (HR = 4.5; 95% CI: 1.66-12.06; P = 0.003), local/systemic recurrence-free survival (HR = 2.5; 95% CI: 1.07-5.64; P = 0.04), and cancer-specific survival (HR = 2.6; 95% CI: 1.05-6.22; P = 0.04). CONCLUSIONS Degree of HN can serve as a surrogate for advanced disease and predict worse oncologic outcomes in HG UTUC. Degree of HN was not predictive of intravesical or local/systemic recurrence in LG UTUC.

Abstract
OBJECTIVES Karakiewicz et al. and Green et al. created pre-cystectomy nomograms to predict lymph node involvement. The aim of the study was to externally validate these two nomograms in intermediate-volume institutions in Europe. PATIENTS AND METHODS Data from a Serbian single-centre cystectomy series comprising 183 patients with bladder cancer were used for the validation of two US nomograms, which were originally based on data from 726 and 201 patients, respectively. A multivariate regression model assessed the value of the clinical parameters integrated in the two nomograms. The expected predictive accuracy, calibration and clinical utility according to the nomograms were calculated. RESULTS Comparison of our dataset with the previously published data shows differences in nearly all underlying risk variables. Overall, 109 (59.6 %) patients had lymph node metastases. The analysis demonstrated that hydronephrosis and status of lymph nodes on computed tomography have independent prognostic value. The performance of the nomograms deteriorated from the development set, and the predictive accuracies for the two models showed moderate discriminatory ability (61.2-69.1 %). In the decision curve analysis, only the Green et al. model predicting lymph node positivity provided net benefit. CONCLUSIONS The Green et al. nomogram seems applicable to patients from Europe, despite varying risk factors in the validation dataset. Acceptance of such a tool into daily clinical management may lead to more appropriate decision-making. Nevertheless, further improvement and implementation of novel statistical models with enhanced predictive accuracy is needed.

Abstract
OBJECTIVE To evaluate predictors of understaging in patients with presumed non-muscle-invasive bladder cancer (NMIBC) identified on transurethral resection of bladder tumour (TURBT) who underwent radical cystectomy (RC) with attention to the role of a restaging TURBT. PATIENTS AND METHODS We retrospectively evaluated 279 consecutive patients with clinically staged T1 (cT1) disease after TURBT who underwent RC at our institution from April 2000 to July 2011. In all, 60 of these cT1 patients had undergone a restaging TURBT before RC. The primary outcome measure was pathological staging of ≥T2 disease at the time of RC. RESULTS In all, 134 (48.0%) patients were understaged. Of the 60 patients who remained cT1 after a restaging TURBT, 28 (46.7%) were understaged. Solitary tumour (odds ratio [OR] 0.43, 95% confidence interval [CI] 0.25-0.76, P = 0.004) and fewer prior TURBTs (OR 0.84, 95% CI 0.71-1.00, P = 0.05) were independent risk factors for understaging. CONCLUSIONS Despite the overall improvement in staging accuracy linked to restaging TURBTs, the risk of clinical understaging remains high in restaged patients found to have persistent T1 urothelial carcinoma who undergo RC. Solitary tumour and fewer prior TURBTs are independent risk factors for being understaged. Incorporating these predictors into preoperative risk stratification may allow for augmented identification of those patients with clinical NMIBC who stand to benefit most from RC.

Abstract
PURPOSE We evaluated the survival of patients with muscle invasive bladder cancer undergoing radical cystectomy without neoadjuvant chemotherapy to confirm the utility of existing clinical tools to identify low risk patients who could be treated with radical cystectomy alone and a high risk group most likely to benefit from neoadjuvant chemotherapy. MATERIALS AND METHODS We identified patients with muscle invasive bladder cancer who underwent radical cystectomy without neoadjuvant chemotherapy at our institution between 2000 and 2010. Patients were considered high risk based on the clinical presence of hydroureteronephrosis, cT3b-T4a disease, and/or histological evidence of lymphovascular invasion, micropapillary or neuroendocrine features on transurethral resection. We evaluated survival (disease specific, progression-free and overall) and rate of pathological up staging. An independent cohort of patients from another institution was used to confirm our findings. RESULTS We identified 98 high risk and 199 low risk patients eligible for analysis. High risk patients exhibited decreased 5-year overall survival (47.0% vs 64.8%) and decreased disease specific (64.3% vs 83.5%) and progression-free (62.0% vs 84.1%) survival probabilities compared to low risk patients (p <0.001). Survival outcomes were confirmed in the validation subset. On final pathology 49.2% of low risk patients had disease up staged. CONCLUSIONS The 5-year disease specific survival of low risk patients was greater than 80%, supporting the distinction of high risk and low risk muscle invasive bladder cancer. The presence of high risk features identifies patients with a poor prognosis who are most likely to benefit from neoadjuvant chemotherapy, while many of those with low risk disease can undergo surgery up front with good expectations and avoid chemotherapy associated toxicity.

Abstract
OBJECTIVE To investigate preoperative predictors of ureteral involvement of bladder malignancy and to develop a novel preoperative model for the prediction of ureteral involvement in bladder cancer patients undergoing radical cystectomy. METHODS This study included 197 consecutive bladder cancer patients treated with radical cystectomy. The correlations of preoperative factors with ureteral involvement were analyzed by univariate analysis with Pearson's χ(2-) test and multivariate logistic regression analysis with a stepwise selection procedure. RESULTS Positive ureteral involvement was observed in 38 (19.3%) patients. Tumor location (involvement of the vesical trigone), clinical T stage (≥ cT3) and the number of tumors (≥ 3), but not sex, tumor grade and histological features determined by transurethral resection of bladder tumor, tumor size, shape of tumor, concomitant presence of carcinoma in situ, preoperative intravesical therapy, number of transurethral resection of bladder tumor procedures or the presence of hydronephrosis were significantly associated with ureteral involvement in the univariate analysis. Multivariate logistic regression analysis confirmed that the aforementioned three significant factors identified in the univariate analysis were significant independent predictors of ureteral involvement. The probability of ureteral involvement estimated by a combination of these three parameters was well correlated with the real incidence (R = 0.904, P = 0.0021). CONCLUSIONS Tumor location (involvement of vesical trigone), clinical T stage (≥ cT3) and the number of tumors (≥ 3) are significant independent preoperative predictors of ureteral involvement of malignancy in bladder cancer patients undergoing radical cystectomy. Our predictive model might be useful for preoperative prediction of ureteral tumor involvement.

Abstract
OBJECTIVE Preoperative prognostic factors in bladder cancer patients have not been fully established. This study was undertaken to investigate preoperative prognostic factors, including neutrophil-to-lymphocyte ratio (NLR), and to develop a novel prognostic factors-based risk stratification model for disease-specific survival (DSS) in bladder cancer patients treated with radical cystectomy (RC). METHODS We performed a retrospective analysis of 189 consecutive bladder cancer patients treated with RC at our institution. Prognostic value of the preoperative clinical and laboratory parameters were evaluated by univariate and multivariate Cox proportional hazard model analyses, and patients were stratified according to relative risks (RRs) for DSS. RESULTS One-, 3-, and 5-year DSS rates were 86.8%, 70.8%, and 61.7%, respectively. In univariate analysis, tumor size, clinical T stage, hydronephrosis, concomitance of carcinoma in situ, and some laboratory findings (hemoglobin [Hb] level, platelet count, C-reactive protein, neutrophil count, lymphocyte count, and NLR) were significantly associated with poor prognosis. In multivariate analysis, tumor size, hydronephrosis, Hb level, and NLR were independent factors for predicting poor prognosis. Patients were stratified into 3 risk groups: low (RR = 1.000-3.717), intermediate (RR = 4.149-9.315), and high (RR = 10.397-38.646). The differences among the groups were significant. CONCLUSIONS NLR was an independent prognostic factor, as were tumor size, hydronephrosis, and Hb levels, and the combination of these factors can stratify DSS risks in bladder cancer patients treated with RC. This information may be useful for identifying patients who might be candidates for clinical trials of multimodal treatment strategies, including innovative neoadjuvant treatments.

Abstract
OBJECTIVE Pre-cystectomy nomograms with a high predictive ability for locally advanced urothelial carcinomas of the bladder would enhance individual treatment tailoring and patient counselling. To date, there are two currently not externally validated nomograms for prediction of the tumour stages pT3-4 or lymph node involvement. MATERIALS AND METHODS Data from a German multicentre cystectomy series comprising 2,477 patients with urothelial carcinoma of the bladder were applied for the validation of two US nomograms, which were originally based on the data of 726 patients (nomogram 1: prediction of pT3-4 tumours, nomogram 2: prediction of lymph node involvement). Multivariate regression models assessed the value of clinical parameters integrated in both nomograms, i.e. age, gender, cT stage, TURB grade and associated Tis. Discriminative abilities of both nomograms were assessed by ROC analyses; calibration facilitated a comparison of the predicted probability and the actual incidence of locally advanced tumour stages. RESULTS Of the patients, 44.5 and 25.8% demonstrated tumour stages pT3-4 and pN+, respectively. If only one case of a previously not known locally advanced carcinoma (pT3-4 and/or pN+) is considered as a staging error, the rate of understaging was 48.9% (n=1211). The predictive accuracies of the validated nomograms were 67.5 and 54.5%, respectively. The mean probabilities of pT3-4 tumours and lymph node involvement predicted by application of these nomograms were 36.7% (actual frequency 44.5%) and 20.2% (actual frequency 25.8%), respectively. Both nomograms underestimated the real incidence of locally advanced tumours. CONCLUSIONS The present study demonstrates that prediction of locally advanced urothelial carcinomas of the bladder by both validated nomograms is not conferrable to patients of the present German cystectomy series. Hence, there is still a need for statistical models with enhanced predictive accuracy.

Abstract
OBJECTIVE In an effort to standardize data collection for research regarding bladder cancer, the Bladder Cancer Working Group sought to provide a handbook that can be used as a guide for prospective or retrospective data collection. METHODS Expert opinions for various data groups were compiled through a team of researchers at the BCAN. Peer review of each data group was performed from within the group. RESULTS Essential and comprehensive data elements are provided for 9 groups of data elements, including demographics, comorbidities, staging, laboratory data, operative details, pathology, complications, outcomes, and quality of life measurements. CONCLUSIONS Establishment of a comprehensive bladder cancer database is important in initiating multicenter collaborations. While not every data point is critical, this review may be useful in serving as a reference in initiating projects and providing a framework for collaborations.

Abstract
PURPOSE OF REVIEW To review the epidemiology, diagnosis, and management of all stages of bladder cancer with an emphasis on studies published within the last year. RECENT FINDINGS Smoking continues to be the most important risk factor for the development of bladder cancer, and this risk has increased over time. Although a number of urinary markers for bladder cancer are now approved by the Food and Drug Administration, there is not enough evidence that any marker can replace surveillance cystoscopy. Management of high-risk patients with nonmuscle-invasive cancer remains a challenge, with continued controversy over which patients may safely be treated with bladder-sparing regimens. Efforts toward developing agents for bacillus Calmette-Guerin-refractory superficial bladder cancer continue, however, none to date have shown high rates of long-term success. In patients undergoing cystectomy, reports using more standardized measures of complications have demonstrated high rates of postoperative morbidity and mortality, particularly in elderly individuals. Robot-assisted radical cystectomy is being more widely studied as a potential approach to decrease operative blood loss and shorten recovery. Although more expensive, increasing evidence suggests that it is well tolerated, does not increase the risk of positive surgical margins, and can achieve similar lymph node counts as open cystectomy in experienced hands and with careful patient selection. Despite level I evidence supporting the use of neoadjuvant chemotherapy, there remains disagreement regarding its use vs. selective adjuvant therapy, given the modest benefits seen with current regimens. SUMMARY Progress continues in bladder cancer diagnosis and management, and we anticipate that future work will further advance the care of patients with this disease.

Abstract
Upper urinary tract urothelial carcinoma (UTUC) is a rare disease, which means there are little evidence-based data available to guide clinical decision-making. Although diagnosis and treatment of UTUC have improved significantly over the last 5 years, accurate risk stratification remains a challenge owing to the difficulty of clinical staging. A number of potential prognostic factors have been identified, encompassing clinical characteristics, pathological factors and molecular markers. Tumor stage and lymph node status are the most important predictors of survival in patients with UTUC. Preoperative evaluation for hydronephrosis can identify patients at risk of non-organ-confined disease. In the subgroup of patients with stage ≥pT2 disease, a longer interval between diagnosis and radical nephroureterectomy is associated with a higher risk of disease recurrence and cancer-specific mortality. Extensive tumor necrosis, sessile tumor architecture and lymphovascular invasion are independent predictors of clinical outcomes for patients with UTUC treated with radical nephroureterectomy. The incorporation of such prognosticators into clinical prediction models might help to guide decision-making with regard to timing of surveillance, type of treatment, performance of lymphadenectomy, and consideration of neoadjuvant or adjuvant systemic therapies.
