Abstract
Non-muscle-invasive bladder cancer (NMIBC) is a common urinary tumor and has a high recurrence rate due to improper or inadequate conservative treatment. The early and accurate prediction of its recurrence can be helpful to implement timely and rational treatment. In this study, we explored a preoperative serum surface-enhanced Raman spectroscopy based prognostic protocol to predict the postoperative prognosis for NMIBC patients at the time even before treatment. The biochemical analysis results suggested that biomolecules related to DNA/RNA, protein substances, trehalose and collagen are expected to be potential prognostic markers, which further compared with several routine clinically used immunohistochemistry expressions with prognostic values. In addition, high prognostic accuracies of 87.01% and 89.47% were achieved by using the proposed prognostic models to predict the future postoperative recurrence and recurrent type, respectively. Therefore, we believe that the proposed method has great potential in the early and accurate prediction of postoperative prognosis in patients with NMIBC, which is with important clinical significance to guide the treatment and further improve the recurrence rate and survival time.

Abstract
OBJECTIVE This study aims to establish a nomogram model by combining traditional clinical parameters with immunohistochemical markers to predict the recurrence of non-muscle invasive bladder urothelial carcinoma (NMIBUC) after resection. METHODS In total, 504 patients were included in this study. Of these patients, 353 underwent transurethral resection of bladder tumor (TURBT) in the Yongchuan Hospital of Chongqing Medical University and were identified as a training cohort. Univariate and multivariate Cox regression analyses were used to determine the risk factors associated with recurrence in the training cohort and to establish a nomogram model. A total of 151 patients who were hospitalized in the Second Affiliated Hospital of Chongqing Medical University (validation cohort) were used for further validation. The calibration curve was generated for internal and external model validation. The clinical practicability of this model was further verified by comparing the consistency index (C-index) among various models. RESULTS The mean follow-up time of the training cohort was 45.6 months (range 4-90). In total, 146 patients relapsed in training cohort. After univariate analysis, multivariate analysis further confirmed tumor grade (p=.034), immediate postoperative instillation therapy (p=.025), Ki67 (p=.047), P53 (p=.038) and CK20 (p=.049) as independent risk factors for recurrence, and these factors were included in the nomogram model. The model more accurately predicted recurrence compared with other models based on the highest C-index of 0.82 (95% CI, 0.78-0.86) in the training cohort and 0.80 (95% CI, 0.77-0.83) in the validation cohort. CONCLUSIONS This proposed nomogram model based on traditional clinical parameters and immunohistochemical markers can more accurately predict postoperative recurrence in patients with NMIBUC.

Abstract
Bladder cancer (BC) is the fifth most common cancer with a high prevalence rate. It is classically classified in two groups, namely non-muscle invasive (NMIBC) and muscle invasive (MIBC). NMIBC accounts for 75% of cases and has a better prognosis than MIBC. However, 30-50% of the NMIBC patients will show recurrences throughout their lives, and about 10-20% of them will progress to MIBC, with frequent metastasis and a reduced survival rate. The diagnosis of bladder cancer is confirmed by direct visualization of the tumour and other mucosal abnormalities with endoscopic excision using cystoscopy and transurethral resection of the bladder (TURBT). An adequate TURBT requires complete resection of all visible tumour with appropriate sampling of the bladder to assess the depth of invasion. However, for many years, researchers have attempted to identify and utilise urinary markers for bladder cancer detection. Voided urine cytology has been the mainstay of urine-based diagnosis of bladder cancer since originally described by Papanicolau and Marshall. Nonetheless, urine cytology has several drawbacks, including a poor sensitivity for low-grade/stage tumours, a lack of interobserver consistency and a variable range of readings (e.g., atypical, atypical-suspicious, non-diagnostic). These shortcomings have inspired the search for more sensitive bladder cancer biomarkers. To bring precision medicine to genitourinary oncology, the analysis of the plasma/serum wide genome and proteome offers promising possibilities.

Abstract
Pterin compounds belong to the group of biomarkers for which an increase in interest has been observed in recent years. Available literature data point to this group of compounds as potential biomarkers for cancer detection, although the biochemical justification for this claim is not yet fully understood. The aim of this study was to evaluate the usefulness of pterin compounds in the diagnosis of bladder cancer, with particular emphasis on the role of creatinine and the specific gravity of urine as factors for normalizing the concentration of pterin compounds in urine. The standardization of the concentration of pterin compounds to urine specific gravity allows the building of better classification models for screening patients with potential cancer of the bladder. Of the compounds that make up the pterin profile, isoxanthopterin appears to be a compound that can potentially be described as a biomarker of bladder cancer.

Abstract
Although the incidence varies with age and gender, urothelial bladder cancer is a relatively frequently occurring malignancy with variable clinical behavior that often has high recurrence rates. In this study, we analyzed the tumor tissues of 224 patients with pTa, pT1, and pT2 urinary bladder cancer. We performed a histomorphologic analysis and immunohistochemistry for p53, Ki-67, and E-cadherin, which were selected as markers of the malignant process. For pTa and pT1, univariate analyses of cancer-specific survival (CSS), progression-free survival (PFS), and recurrence-free survival (RFS) were calculated using the Kaplan-Meier method, the logrank test and Cox regression. Multivariate analysis was performed by the Cox regression analysis. Ki-67 (P<0.001) was significantly associated with CSS, but the highest association was shown for E-cadherin (P<0.001). For pT1 and pTa, the Kaplan-Meier analysis and the log-rank test revealed significantly worse PFS for patients with higher levels of Ki-67 (P<0.001) and lower levels of E-cadherin (P<0.001). Based on these obtained results, it can be clearly stated that Ki-67 and E-cadherin expression levels are associated with CSS, PFS and RFS. The clinical utility of these markers is valuable for pTa and pT1 urinary bladder cancer and should be further verified with prospective multi-center trials.

Abstract
Background Bladder cancer was a malignant disease in patients, our research aimed at discovering the possible biomarkers for the diseases. Results The gene chip GSE31684, including 93samples, was downloaded from the GEO datasets and co-expression network was constructed by the data. Molecular complex detection(MCODE) was used to identify hub genes. The most significant cluster including 16 genes: CDH11, COL3A1, COL6A3, COL5A1, AEBP1, COL1A2, NTM, COL11A1, THBS2, COL8A1, COL1A1, BGN, MMP2, PXDN, THY1, and TGFB1I1 was identified. After annotated by BiNGO, they were suggested associated with collagen fibril organization and blood vessel development. In addition, the Kaplan Meier curves were obtained by UALCAN. The high expression of THY1, AEBP1, CDH11, COL1A1, COL1A2, COL11A1, MMP2, PXDN, BGN, COL5A1, COL8A1, and TGFB1I1 indicated poor prognosis of the patients(P < 0.05). Finally, we examined genes’ expression between low and high tumor stage by the Wilcoxon test(P < 0.05), TGFB1I1 was excluded. Conclusion THY1, AEBP1, CDH11, COL1A1, COL1A2, COL11A1, MMP2, PXDN, BGN, COL5A1, COL8A1 associated with the tumor stage as well as tumor patients’ prognosis. COL5A1, COL8A1(P < 0.01) may serve as therapeutic targets for the disease.

Abstract
INTRODUCTION Over the last decade, the improvement in molecular techniques and the acquisition of genomic information has transformed and increased the quality of patient care and our knowledge of diseases. Areas covered: Protein expression levels in immunohistochemistry and molecular biomarkers are reported for their ability to predict recurrence, progression, development of metastases, or patient survival. In particular, for renal cell carcinoma, we take into consideration the biomarkers applicable to immunohistochemistry and with molecular and genetic analyses. In urothelial carcinoma, there is great interest in the possibility of distinguishing the basal vs. luminal subtypes and to acquire deeper insight into the tumor biology through examining exosomes in urine and biomarkers in the serum. In prostate cancer, single gene expression and multiple gene expression classifiers are reviewed as a tool to distinguish indolent vs. aggressive disease. Expert commentary: The genomic information along with the application of ancillary techniques allow the definition of a neoplasia not only by its morphology but also by its biological signature. This continuous increase in knowledge will result in a better comprehension of oncogenesis, development of targeted therapies and optimizing decision-making processes related to patient care.

Abstract
OBJECTIVES The aim of this study was to explore the prognostic value of ki67 as a marker in patients with non-muscle invasive bladder cancer (NMIBC) treated with BCG. METHODS Studies were systematically retrieved from the relevant databases (Web of Science, PubMed, Cochrane Library and Embase), and the expiry date was May 2017. The research steps referred to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement. RESULTS A total of 11 studies that complied with the inclusion criteria were included. The expression of ki67 was not statistically significantly associated with recurrence-free survival (RFS) (HR 1.331; 95% CI 0.980 to 1.809). No significant heterogeneity was found among all included studies (I2 =36.7%, p=0.148). The expression of ki67 was statistically significantly associated with progression-free survival (PFS) (HR 2.567; 95% CI 1.562 to 4.219), and the overexpression of ki67 was the risk factor for PFS. Significant heterogeneity was noted among all the included studies (I2 =55.6%, p=0.021). The studies that might cause heterogeneity were excluded using the Galbraith plot, and then the meta-analysis was performed again. The results showed that the expression of ki67 was still associated with PFS (HR 2.922; 95% CI 2.002 to 4.266). CONCLUSIONS The overexpression of ki67 was the risk factor for PFS, and the relationship between the expression of ki67 and RFS was not statistically significant in patients with NMIBC treated with BCG intravesical immunotherapy. Well-designed, prospective, with a large sample size are still needed to validate the findings.

Abstract
The most frequent diseases of the urinary bladder are bacterial infections and bladder cancers. For both diseases, very high recurrence rates are characteristic: 50⁻80% for bladder cancer and more than 50% for bladder infections, causing loss of millions of dollars per year for medical treatment and sick leave. Despite years of searching for better treatment, the prevalence of bladder infections and bladder cancer remains unchanged and is even increasing in recent years. Very encouraging results in treatment of both diseases recently culminated from studies combining biopolymer chitosan with immunotherapy, and chitosan with antibiotics for treatment of bladder cancer and cystitis, respectably. In both pathways of research, the discoveries involving chitosan reached a successful long-lasting cure. The property of chitosan that boosted the effectivity of illness-specific drugs is its ability to enhance the accessibility of these drugs to the very sources of both pathologies that individual treatments without chitosan failed to achieve. Chitosan can thus be recognised as a very promising co-player in treatment of bladder cancer and bacterial cystitis.

Abstract
Purpose This meta-analysis evaluated the prognostic significance of Ki-67 in non-muscle invasive bladder cancer (NMIBC). Materials and Methods We selected 39 articles including 5,229 patients from Embase, Scopus, and PubMed searches. The primary outcomes, recurrence-free survival (RFS), progression-free survival (PFS), disease-specific survival (DSS), and overall survival (OS) were determined using time-to event hazard ratios (HRs) with 95% confidence intervals (CIs). Study heterogeneity was tested by chi-square and I2 statistics. Heterogeneity sources were identified by subgroup meta-regression analysis. Results Two studies were prospective; 37 were retrospective. Immunohistochemistry was performed in tissue microarrays or serial sections. A wide range of antibody dilutions and Ki-67 positivity thresholds were used. Study heterogeneity was attributed to analysis results in studies of RFS (p < 0.0001). Meta-regression analysis revealed that region and analysis results accounted for heterogeneity in PFS studies (p = 0.00471, p < 0.0001). High Ki-67 expression was associated with poor RFS (pooled HR, 1.78; 95% CI, 1.48–2.15), poor PFS (pooled HR, 1.28; 95% CI, 1.13–2.15), poor DSS (pooled HR, 2.24; 95% CI, 1.47–2.15), and worse OS (pooled HR, 2.29; 95% CI, 1.24–4.22). Conclusions The meta-analysis found that current evidence supports the prognostic value of Ki-67 in NMIBC patients.

Abstract
BACKGROUND Initial diagnosis of carcinoma of the urinary bladder remains challenging. N-Myc downstream-regulated gene 2 (NDRG2) has been reported to be closely correlated with cell differentiation and proliferation in various cancers. However, its clinical significance in diagnosis of bladder cancer remains unclear. The purpose of this study was to detect the expression of NDRG2 and investigate its diagnostic value in bladder cancer. MATERIAL AND METHODS We recruited 127 patients with bladder cancer and 97 healthy controls. Quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR) and Western blotting analysis were conducted to measure the NDRG2 expression levels in urine of patients with bladder cancer, bladder cancer cell lines, and healthy controls. The correlations between NDRG2 expression and clinicopathological characteristics were analyzed by chi-square test, and the diagnostic value of NDRG2 was estimated by establishing a receiver operating characteristic (ROC) curve. RESULTS The relative NDRG2 expression were significantly downregulated both at mRNA and protein levels in urine of patients with bladder cancer and in cell lines, and its low expression was distinctively correlated with tumor grade and stage. The ROC curve showed NDRG2 could be a good diagnostic marker, with an AUC of 0.888, indicating high sensitivity and specificity. CONCLUSIONS NDRG2 was decreased in patients with bladder cancer and might be involved in the progression of this malignancy. Moreover, NDRG2 could be a potential independent diagnostic biomarker for bladder cancer.

CCL21/CCR7 interaction promotes cellular migration and invasion via modulation of the MEK/ERK1/2 signaling pathway and correlates with lymphatic metastatic spread and poor prognosis in urinary bladder cancer. Int J Oncol 2017; 51:75-90. [PMID: 28534984 PMCID: PMC5467787 DOI: 10.3892/ijo.2017.4003] [Citation(s) in RCA: 37] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2016] [Accepted: 05/02/2017] [Indexed: 12/22/2022] Open
Abstract
Lymph node metastasis in patients with urinary bladder cancer (UBC) is always associated with poor prognosis and is the determinant for tumor staging and the development of treatment regimens; however, its underlying mechanisms remain to be studied. Immunohistochemical staining of tumor sections from 62 UBC patients was performed using CCR7, D2-40 and CD34 antibodies. We showed that increased CCR7 expression was significantly associated with positive lymph node status (P=0.008), pT3-T4 tumor stage (P=0.015), tumor grade (P=0.010) and worse overall survival (OS, P<0.001) and that both CCR7 expression and lymph node metastasis were independent prognostic factors for OS (P=0.031 and P=0.001, respectively) based on multivariate analysis. We found that there was a significant association between MLVD and lymph node status (P=0.006), but this relation was not observed for MVD. Furthermore, we showed that increased CCR7 expression correlated significantly with higher MLVD (P=0.014) and MVD (P=0.002). Wound-healing and Matrigel Transwell assays indicated that activation of CCR7 with CCL21 significantly enhanced the invasion and migration abilities of UM-UC-3 cells, and this enhanced effect was significantly abrogated by CCR7 knockdown using siRNA. Western blot analysis revealed that the phospho-ERK1/2 level was markedly increased when UM-UC-3 cells were treated with CCL21 and significantly decreased when the CCR7 gene was silenced. MEK/ERK1/2 inhibition with PD98059 significantly suppressed the migration and invasion abilities of UM-UC-3 cells and also significantly abrogated the effects of CCL21/CCR7 on cell migration and invasion. Based on these results, we conclude that activation of the CCL21/CCR7 chemoaxis promotes lymph node metastasis of UBC in at least two ways. Firstly, although CCR7 is a promoting factor that induces both lymphangiogenesis and angiogenesis, it may promote lymph node metastasis through its lymphangiogenic effect rather than through its angiogenic effect. Secondly, the CCL21/CCR7 chemoaxis promotes the migration and invasion of UBC cells via the MEK/ERK1/2 signaling pathway rather than the PI3K/AKT pathway.

Abstract
Background Endocan (endothelial cell-specific molecule-1) is a proteoglycan and plays an important role in angiogenesis and inflammation. The aim of this study was to evaluate of serum and urinary concentrations of endothelial cell-specific molecule-1 in bladder cancer. Methods The study included 50 bladder cancer patients, 50 with urinary tract infection and 51 healthy volunteers. Serum and urinary endothelial cell-specific molecule-1 concentrations were measured with enzyme linked immunosorbent assay. Results In bladder cancer group, serum and urinary endothelial cell-specific molecule-1 concentrations were significantly higher than in the healthy subjects ( P = 0.003 and P < 0.0001). Urinary endothelial cell-specific molecule-1 concentrations in cases with urinary tract infection were higher than in healthy volunteers ( P = 0.002). There were no significant differences between bladder cancer and urinary tract infection groups in terms of serum and urinary endothelial cell-specific molecule-1 concentrations. Urinary endothelial cell-specific molecule-1 concentrations were higher than those of corresponding serum endothelial cell-specific molecule-1 concentrations ( P < 0.0001 for bladder cancer and urinary tract infection groups, P = 0.002 for healthy subjects). In bladder cancer group, there was a positive correlation between serum endothelial cell-specific molecule-1 and urinary endothelial cell-specific molecule-1 concentrations ( r = 0.32, P = 0.002). For serum endothelial cell-specific molecule-1, sensitivity and specificity were 50%, and 77%, and for urinary endothelial cell-specific molecule-1, 62%, and 71%, respectively. Conclusion Serum and urinary endothelial cell-specific molecule-1 concentrations increase in bladder cancer. This parameter also increases in serum and urine of cases with urinary tract infection. That urinary endothelial cell-specific molecule-1 values were higher than serum endothelial cell-specific molecule-1 values in all groups may be attributed to direct exfoliation of epithelial cells in bladder to urine.

Abstract
Cancers often utilize microRNAs to suppress tumor suppressor genes, thus facilitating their potential for growth and invasion. In the present study, we report the novel findings that miR-892b inhibits proliferation, migration and invasion of bladder cancer cells. The basal expression level of miR‑892b was significantly lower in 3 different bladder cancer cell lines than in normal human urothelial cells. Transfection of miR-892b mimics to bladder cancer cells resulted in dose‑dependent growth arrest. Flow cytometric analysis of the cell cycle showed that miR-892b-transfected bladder cancer cells were subject to arrest in the G1 phase, which was due to the downregulation of cyclin D1 and CDK6 followed by upregulation of p19ARF. In addition, overexpression of miR-892b impeded the migration and invasion of EJ cells. Expression of MMP-9 in EJ cells was blocked by transfection of miR-892b; the effect was regulated, at least in part, by activation of the Sp-1 transcription factor. Overall, we verified that miR-892b regulates the p19ARF/cyclin D1/CDK6 and Sp-1/MMP-9 signaling networks in bladder cancer cells and may provide a treatment option for advanced-stage bladder cancers.

Abstract
Non-muscle-invasive bladder cancer (NMIBC) may progress to muscle-invasive disease, but no effective preventive treatments are available. In addition, no reliable prognostic biomarkers have been identified. We assessed the long-term effect of the oral retinoid fenretinide and the prognostic value of circulating VEGF levels. We updated through the Tumor Registry the vital status of 99 patients with resected Ta/T1 bladder tumors who were recruited in a randomized trial of 2 years of fenretinide or no treatment in 1993-1994. Serum VEGF levels measured at baseline and 12 months were available in a subgroup of 62 patients. After a median of 20.5 years, 54 subjects died, 35 of any cancer and 14 of bladder cancer. Neither overall survival (OS), nor cancer survival (CS) or bladder cancer survival (BCS) was affected by fenretinide (log-rank P ≥ 0.2). DNA aneuploidy in bladder washing was associated with shorter OS (P = 0.02), CS (P = 0.05), and BCS (P = 0.09). Subjects with baseline VEGF levels in the top quintile (≥350 pg/mL) had a significantly shorter OS (P = 0.01), CS (P = 0.02), and BCS (P = 0.008). The trend across quintiles of VEGF was significant for BCS (P = 0.007). Multivariate analyses showed that, in addition to smoking status, VEGF level in the top quintile was an independent prognostic factor for OS (HR = 2.7; 95% CI, 1.1-6.5), CS (HR = 3.3; 95% CI, 1.1-9.4) and BCS (HR = 8.9; 95% CI,1.3-61). Fenretinide did not affect the long-term outcome of patients with NMIBC. High serum VEGF level was a significant predictor of overall and cancer death and may help to identify high-risk subjects who may benefit from a preventive therapy.

Abstract
Krüppel-like factor 4 (KLF4) is a transcription factor involved in both tumor suppression and oncogenesis as a transcriptional activator or repressor in a context-dependent manner. KLF4 acts as a regulator of p53 depending on p21 status in breast cancer. However, the mechanisms underlying the distinct role of KLF4 remain poorly understood. Here, we revealed that p21 depletion converted KLF4 from a cell cycle inhibitor to a promoter of bladder cancer cell proliferation. Additionally, KLF4 was acetylated in a p21-dependent manner to inhibit bladder cancer cell growth as a tumor suppressor. However, deacetylated KLF4 functioned as an oncogene promoting bladder cancer cell proliferation. Mechanistically, p21 and CK2 interaction, but not CK2 alone, enhanced HDAC2 phosphorylation and restricted KLF4 deacetylation and subsequent tumor promotion. Furthermore, we observed that KLF4 was acetylated by CBP/p300 and that overexpression of CBP resulted in KLF4 acetylation and tumor suppression even in p21-depleted bladder cancer cells. Moreover, we discovered that Notch-1 knockdown-induced KLF4 is acetylated form of KLF4, which may mediate Notch-1 function in bladder cancer cell proliferation. Our data demonstrate that KLF4 acts as a tumor suppressor or oncogene to activate or repress target gene transcription depending on its acetylation status, which is regulated by p21 and CK2 interaction-mediated HDAC2 phosphorylation. Targeting KLF4 at the post-transcriptional levels may provide novel insight for bladder cancer therapy.

Abstract
A non-invasive marker is required for the diagnosis and follow-up of patients with bladder cancer. The aim of the current study was to evaluate the potential prognostic significance of serum osteoprotegerin (OPG), p53 protein and urine telomerase in patients with bladder cancer. For all patients, serum levels of OPG and p53 protein were determined using enzyme-linked immunosorbent assay (ELISA), and urine telomerase was assessed using a polymerase chain reaction ELISA technique. Patients were assigned into group 1 (cystectomy and adjuvant radiotherapy) or group 2 (transurethral resection and chemoradiotherapy). The results revealed that serum OPG and p53, and urine telomerase levels were significantly higher in bladder cancer patients compared with in healthy individuals (P<0.0001). High serum OPG was associated with significantly lower overall survival and disease-free survival rates (both P=0.001), and was correlated with advanced tumor stages (P<0.0001), high tumor grades (P<0.0001) and the occurrence of disease relapse (P=0.001). Serum p53 and urine telomerase did not demonstrate prognostic significance. These findings indicate that serum OPG level may be used as a diagnostic tool and a prognostic variable for patients with muscle invasive bladder cancer. Future trials are required to elucidate its therapeutic role in such patients.

Abstract
MicroRNA (miRNA) expression profile analysis indicated that miR-205 was upregulated in bladder cancer tissue compared to healthy tissue. The aim of this study is to analyze value of circulating miR-205 for the detection and prognosis evaluation of bladder cancer (BC). Eighty-nine patients with BC and 56 healthy controls (HC) were enrolled in the study. miR-205 expression was determined using TaqMan quantitative real-time polymerase chain reaction assay and further correlated with patients' clinicopathological parameters and follow-up data. The results indicated that plasma miR-205 was upregulated in BC compared with HC (P < 0.001) and in muscle invasive BC (MIBC) compared to nonmuscle invasive BC (NMIBC) (P = 0.016). miR-205 yielded an area under the receiver-operating characteristic curve of 0.950 with 76.4 % sensitivity and 96.4 % specificity in discriminating BC from HC, and 0.668 with 57.1 % sensitivity and 77.0 % specificity in distinguishing MIBC from NMIBC. Plasma miR-205 expression was significantly associated with tumor stage (P < 0.001) and pathological grade (P = 0.048). The results indicated that BC patients with high miR-205 expression experienced shorter disease-free survival and disease-specific survival (P = 0.022 and P = 0.026; P = 0.027 and P = 0.034; respectively), which was not proven by multivariate Cox regression analysis (multi-Cox) (P = 0.0765 and P = 0.279, respectively). Log-rank test showed that NMIBC patients with high miR-205 expression experienced shorter cancer-free survival (P = 0.044). Log-rank test and univariate and multivariate Cox regression analyses did not indicate that high miR-205 expression in NMIBC patients was associated with cancer-specific survival (P = 0.079, P = 0.089, and P = 0.201, respectively). In conclusion, miR-205 may be a promising biomarker for the detection and prognosis evaluation of BC.

Abstract
INTRODUCTION Non-muscle invasive bladder cancer (NMIBC) comprises about 70% of all newly diagnosed bladder cancer, and includes tumors with stage Ta, T1 and carcinoma in situ (CIS.) Since, NMIBC patients with progression to muscle-invasive disease tend to have worse prognosis than with patients with primary muscle-invasive disease, there is a need to significantly improve risk stratification and earlier definitive treatment for high-risk NMIBC. MATERIALS AND METHODS A detailed Medline search was performed to identify all publications on the topic of prognostic factors and risk predictions for superficial bladder cancer/NMIBC. The manuscripts were reviewed to identify variables that could predict recurrence and progression. RESULTS The most important prognostic factor for progression is grade of tumor. T category, tumor size, number of tumors, concurrent CIS, intravesical therapy, response to bacillus Calmette-Guerin at 3- or 6-month follow-up, prior recurrence rate, age, gender, lymphovascular invasion and depth of lamina propria invasion are other important clinical and pathological parameters to predict recurrence and progression in patients with NMIBC. The European Organization for Research and Treatment of Cancer (EORTC) and the Spanish Club UrológicoEspañol de Tratamiento Oncológico (CUETO) risk tables are the two best-established predictive models for recurrence and progression risk calculation, although they tend to overestimate risk and have poor discrimination for prognostic outcomes in external validation. Molecular biomarkers such as Ki-67, FGFR3 and p53 appear to be promising in predicting recurrence and progression but need further validation prior to using them in clinical practice. CONCLUSION EORTC and CUETO risk tables are the two best-established models to predict recurrence and progression in patients with NMIBC though they tend to overestimate risk and have poor discrimination for prognostic outcomes in external validation. Future research should focus on enhancing the predictive accuracy of risk assessment tools by incorporating additional prognostic factors such as depth of lamina propria invasion and molecular biomarkers after rigorous validation in multi-institutional cohorts.

Matullo G, Naccarati A, Pardini B. MicroRNA expression profiling in bladder cancer: the challenge of next-generation sequencing in tissues and biofluids. Int J Cancer 2015; 138:2334-45. [PMID: 26489968 DOI: 10.1002/ijc.29895] [Citation(s) in RCA: 52] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2015] [Revised: 10/09/2015] [Accepted: 10/19/2015] [Indexed: 01/01/2023]
Abstract
Bladder cancer (BC) is a heterogeneous disease characterized by a high recurrence rate that necessitates continuous cystoscopic surveillance. MicroRNAs (miRNAs) are detectable in tissues and biofluids such as plasma/serum and urine. They represent promising biomarkers with potential not only for detecting BC but also informing on prognosis and monitoring treatment response. In this review, the many aspects of the application of next-generation sequencing (NGS) to evaluate miRNA expression in BC is discussed, including technical issues as well as a comparison with results obtained by qRT-PCR. The available studies investigating miRNA profiling in BC by NGS are described, with particular attention to the potential applicability on biofluids. Altered miRNA levels have been observed in BC tissues by NGS, but these results so far only partially overlapped among studies and with previous data obtained by qRT-PCR. The discrepancies can be ascribed to the small groups of BC patients sequenced. The few available studies on biofluids are mainly focused on implementing RNA isolation and sequencing workflow. Using NGS to analyze miRNAs in biofluids can potentially provide results comparable to tissues with no invasive procedures for the patients. In particular, the analyses performed on exosomes/microvesicles appear to be more informative. Thanks to the improvement of both wet-lab procedures and pipelines/tools for data analyses, NGS studies on biofluids will be performed on a larger scale. MiRNAs detected in urine and serum/plasma will demonstrate their potentiality to describe the variegated scenario of BC and to become relevant clinical markers.

Abstract
Chemokine C-X-C motif ligand 5 (CXCL5) is critical for bladder cancer growth and progression. Our previous study demonstrated that increase of CXCL5 in bladder cancer cell lines had an effect on tumor growth and progression. This study aims to investigate the expression of CXCL5 in tissue and urine of bladder cancer patients, in relation to clinicopathologic parameters, and as a predictive value in diagnosing and evaluating bladder cancer. Urothelial bladder cancer tissues from 255 patients were profiled for CXCL5 alterations by immunohistochemistry. Urine samples collected from patients with bladder cancer and urinary tract infections as well as healthy volunteers were analyzed by ELISA. High expression of CXCL5 in bladder cancer tissue was correlated with TNM stage (P = 0.012), cancer grade (P = 0.001), and lymph node metastasis (P = 0.007). CXCL5 alterations were associated with overall survival (P = 0.007), progression free survival (P = 0.004), and recurrence free survival in muscle invasive bladder cancers (P = 0.026). CXCL5 expression in the urine of bladder cancer patients was significantly different from urinary tract infection patients (P = 0.001) and healthy volunteers. However, urine leukocytes may predict CXCL5 levels (β = 0.56, P < 0.001, R (2) = 0.314). CXCL5 expression in urine was also related to bladder cancer TNM stage (P = 0.039), lymph node metastasis (P = 0.023), tumor size (P = 0.007), and tumor grade (P = 0.005). The sensitivity and specificity for CXCL5/creatinine in predicting bladder cancer were 80.4 and 61.3 %, respectively. These results suggest increased CXCL5 expression in cancer tissue predicts poor survival in bladder cancer patients. CXCL5 expression in urine is useful in a minimally invasive modality for bladder cancer diagnosis. However, urine leukocytes are significant predictors of CXCL5 levels and may affect its result in bladder cancer diagnosis.

Abstract
Golgi phosphoprotein 3 (GOLPH3) has been reported to be involved in the development of several human cancers. However, its clinical significance and biological role in bladder cancer remains unclear. In this study, we sought to analyze the GOLPH3 expression in bladder cancer samples and cells, and explore its clinical significance and biological role. We found that GOLPH3 was significantly increased in bladder cancer tissues and cells. Overexpression of GOLPH3 had significant correlation with poorer survival for bladder cancer patients treated by cystectomy. Knockdown of GOLPH3 inhibited the proliferation, migration and invasion of cancer cells, and tumor growth in a xenograft mouse model. GOLPH3 silencing inhibited AKT/m-TOR signaling, increased the cyclin-dependent kinase (CDK) inhibitor p27 and decreased the CDK regulator cyclin D1 and matrix metallopeptidase 9 (MMP9). Thus, GOLPH3 is likely to play important roles in bladder cancer progression via modulating AKT/mTOR signaling, and it is a novel prognostic biomarker and promising therapeutic target for bladder cancer.

Abstract
BACKGROUND Molecular prognostic markers have been under investigation for the last decade and no validated marker to date has been proven to be used in daily clinical practice for urinary bladder cancers. The aim of the present study is to evaluate the significance of HYAL-1 expression in prediction of recurrence and progression in pT1 urothelial carcinomas. MATERIALS AND METHODS Eighty-nine urothelial carcinoma cases staged as T1 according to 2004 WHO classification were studied. Representative sections from every case were stained immunohistochemically for HYAL-1 and scored between 0 and +3, according to staining density, and graded as low and high for the scores 0-1 and 2-3, respectively. RESULTS Of the 89 pT1 bladder cancer patients, HYAL-1 expression was high in 92.1% (82 patients; 72 patients +3 and 10 patients +2) and low in 7.9% (only 7 patients; 6 patients +1 and 1 patient 0) of the cases. Of the 89 patients, 38 (42.7%) had recurrence and 22 (24.7%) showed progression. HYAL-1 staining did not show significant characteristics for tumor grade, accompanying CIS, multiplicity, tumor size, age and sex. HYAL-1 expression did not have any prognostic value in estimating recurrence or progression. CONCLUSIONS HYAL-1 expression was found to be high, but did not have any prognostic importance in T1 bladder urothelial carcinomas.

Abstract
Nonmuscle invasive (NMI) urothelial cancer (UC) is associated with varied biological potential. It is characterized by frequent recurrence and progression, which thus worsens the oncological outcome. Nearly three-quarters of NMI UCs recur within 5 years, whereas half can progress during follow-up. Progression is particularly seen in T1 and carcinoma in situ (CIS). Undoubtedly, NMI UC is one of the most expensive cancers to manage. The European Organisation for Research and Treatment of Cancer (EORTC) risk calculator is a commonly used tool for assessing the recurrence and progression potential of a newly diagnosed cancer. The parameters used in the assessment are tumor size and number, pathological stage and grade of the cancer, presence of CIS, and prior recurrence rate. The main advantages of the EORTC tool are its ease of use and the lack of need to run expensive molecular tests. However, reproducibility of pathologic stage and grade is modest, which is a concern to clinicians. Molecular markers have potential for predicting the clinical outcome of NMI UC, given that clinico-pathologic variables are not sufficient for prediction of prognosis in an individual. Significant work has been done in the past 2 decades in understanding the molecular biology of bladder cancer; however, the translational value of this knowledge remains poor. The role for molecular markers in predicting recurrence seems limited because multifocal disease and incomplete treatment are probably more important for recurrence than the molecular features of a resected tumor. Urinary markers have very limited value in prognostication of bladder cancer and are used (mainly as an adjunct to cytology) for detection and surveillance of urothelial cell cancer recurrence. Prediction of progression with molecular markers holds considerable promise. Nevertheless, the contemporary value of molecular markers over clinico-pathologic indexes is limited.

Abstract
Clinical use of proteomic biomarkers has the potential to substantially improve the outcomes of patients with bladder cancer. An unmet clinical need evidently exists for noninvasive biomarkers, which might enable improvements in both the diagnosis and prognosis of patients with bladder cancer, as well as improved monitoring of patients for the presence of recurrence. Urine is considered the optimal noninvasive source of proteomic biomarkers in patients with bladder cancer. Currently, a number of single-protein biomarkers have been detected in urine and tissue using a variety of proteomic techniques, each having specific conceptual considerations and technical implications. Promising preclinical data are available for several of these proteins; however, the combination of single urinary proteins into multimarker panels might better encompass the molecular heterogeneity of bladder cancer within this patient population, and prove more effective in clinical use.

Abstract
Background Chromosomal instability in exfoliated urothelial cells has been associated with the development of bladder cancer. Here, we analyzed the accumulation of copy number variations (CNVs) using fluorescence in situ hybridization in cancer cases and explored factors associated with the detection of CNVs in tumor-free men. Methods The prospective UroScreen study was designed to investigate the performance of UroVysion™ and other tumor tests for the early detection of bladder cancer in chemical workers from 2003–2010. We analyzed a database compiling CNVs of chromosomes 3, 7, and 17 and at 9p21 that were detected in 191,434 exfoliated urothelial cells from 1,595 men. We assessed the accumulation of CNVs in 1,400 cells isolated from serial samples that were collected from 18 cancer cases up to the time of diagnosis. A generalized estimating equation model was applied to evaluate the influence of age, smoking, and urine status on CNVs in cells from tumor-free men. Results Tetrasomy of chromosomes 3, 7 and 17, and DNA loss at 9p21 were the most frequently observed forms of CNV. In bladder cancer cases, we observed an accumulation of CNVs that started approximately three years before diagnosis. During the year prior to diagnosis, cells from men with high-grade bladder cancer accumulated more CNVs than those obtained from cases with low-grade cancer (CNV < 2: 7.5% vs. 1.1%, CNV > 2: 16-17% vs. 9-11%). About 1% of cells from tumor-free men showed polysomy of chromosomes 3, 7, or 17 or DNA loss at 9p21. Men aged ≥50 years had 1.3-fold more cells with CNVs than younger men; however, we observed no further age-related accumulation of CNVs in tumor-free men. Significantly more cells with CNVs were detected in samples with low creatinine concentrations. Conclusions We found an accumulation of CNVs during the development of bladder cancer starting three years before diagnosis, with more altered cells identified in high-grade tumors. Also, a small fraction of cells with CNVs were exfoliated into urine of tumor-free men, mainly exhibiting tetraploidy or DNA loss at 9p21. Whether these cells are preferentially cleared from the urothelium or are artifacts needs further exploration.

Abstract
The aims of this study are to analyze the association of microRNA-141 (miR-141) with the clinicopathological parameters of bladder cancer and evaluate the value of miR-141 in predicting the prognosis of bladder cancer. In this study, 114 patients with bladder cancer were enrolled in the study, and tissue specimens were obtained from the tumor zone and from adjacent normal area. miR-141 expression was determined using SYRB Green quantitative real-time polymerase chain reaction assay and was further correlated with patients' clinicopathological parameters and the follow-up data. The results indicated that miR-141 was upregulated in malignant bladder specimens compared with normal ones (P < 0.001). miR-141 expression was significantly associated with tumor stage (P < 0.001), tumor grade (P < 0.001), and muscle invasion status (P < 0.001). Log-rank test showed that the higher miR-141 expression was associated with longer disease-specific survival of the patients with bladder cancer (P < 0.001), which was also proven by univariate and multivariate Cox regression analysis (P < 0.001 and P = 0.039, respectively). Focusing on patients with non-muscle invasive bladder cancer, univariate analysis using log-rank test and Cox regression analysis found that patients with high miR-141 expression experienced longer disease-free survival (P = 0.031 and P = 0.040, respectively) and disease-specific survival (P = 0.028 and P = 0.038, respectively), which was confirmed by multivariate Cox regression analysis (P = 0.036 and P = 0.042, respectively). In conclusion, this study showed that miR-141 may contribute to the progression of bladder cancer and its upregulation may be independently associated with favorable prognosis of bladder cancer, suggesting that miR-141 might serve as a promising biological marker for further risk stratification in the management of bladder cancer.

Abstract
Inhibition of Notch signaling pathways, consisting of 4 highly conserved receptors (Notch 1-4), induces expression of Krüppel-like transcription factors (KLFs) linked to bladder cancer tumorigenesis and metastasis. Effects of Notch-1 knockdown on cell proliferation, differentiation and KLF4 levels in bladder cancer cell lines were investigated. PsiRNA1‑mediated Notch-1 and KLF4 knockdown models and control model without the psiRNA1 vector were constructed using bladder cancer cell lines T24 and BIU87. Cell proliferation, apoptosis and expression of Notch-1 and KLF4 were assessed using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, flow cytometry assay with Annexin V-FITC/PI staining, and reverse transcriptase polymerase chain reaction (RT-PCR) and western blot analysis, respectively. Proliferation was assessed in Notch-1 and/or KLF4 knockdown. The results showed that Notch-1 mRNA and protein expression levels were significantly lower following psiRNA1 vector transfection in both cell lines (P<0.05). Growth and proliferation of both cell lines were significantly inhibited by Notch-1 knockdown (P<0.05), and more G0/G1 arrest and apoptosis were observed compared to those in the control groups (P<0.05). The effects were time-dependent, peaking between 24-48 h and declining by 72 h. KLF4 expression was significantly higher in the Notch-1 knockdown group than in control cells (P<0.05). Notch-1 knockdown cell proliferation was significantly lower than that of Notch-1 and KLF4 knockdown (P<0.05). In conclusion, Notch-1 may act as an oncogene, regulating the proliferation and differentiation of bladder cancer cells by inhibiting KLF4. Pending further exploration of pathway variations and crosstalk, these pathways may be useful targets for bladder cancer therapy.

Abstract
A majority of patients with bladder cancer present with superficial disease and subsequently, some patients show progression to muscle invasive or metastatic disease. Bladder cancer has a complex genetic process and identification of the genetic alterations which occur during progression may lead to the understanding of the nature of the disease and provide the possibility of early treatment. The aim of the present study was to compare the structural and numerical chromosomal differences and changes in the p16 and p53 genes between low-grade (LG) and high-grade (HG) bladder cancer (BC) using cytogenetic and molecular cytogenetic methods. Between March 2009 and March 2010, cytogenetic analyses were carried out on tumor and blood samples in 34 patients with transitional cell type BC, and on blood samples of 34 healthy patients as a control group. Fluorescence in situ hybridization probes for the p16 and p53 genes were also used to screen the alterations in these genes in 32 patients with BC. The patients were divided into two groups (LG and HG) and the findings were compared. A total of 11 (32.3%) patients exhibited LGBC, 22 (64.7%) exhibited HGBC and one (3%) patient exhibited carcinoma in situ. There were no differences between the LGBC and HGBC groups according to the number of chromosomal aberrations (P=0.714); however, differences between alterations of the p16 and p53 genes were significant (P=0.002 and P=0.039). Almost all structural abnormalities were found to be located to the 1q21, 1q32, 3p21 and 5q31 regions in patients with HG tumors. In conclusion, the p16 and p53 genes were altered more prominently in patients with HG tumors compared with LG tumors. The structural abnormalities in the 1q21, 1q32, 3p21 and 5q31 regions were observed more frequently in patients with HG tumors. These regions may play significant roles in the progression of BC, but further studies are required to find candidate genes for a panel of BC.

Abstract
In total, 70-80% of newly diagnosed bladder cancers are confined to the mucosa and staged as Ta, T1 or carcinoma in situ according to the 2002 tumor, lymph nodes and metastasis classification. The standard treatment for these nonmuscle-invasive bladder cancers is transurethral tumor resection with or without adjuvant intravesical chemotherapy or intravesical immunotherapy and subsequent follow-up. Diagnosis and follow-up of nonmuscle-invasive bladder cancer offers two main problems. First, approximately 10-20% of all tumors are not seen in standard cystoscopy. Additionally, frequently repeated follow-up cystoscopies are bothersome for the patient. As an adjunct to standard cystoscopy, fluorescence-guided cystoscopy has demonstrated significantly higher tumor detection rates and optimized patient treatment in recent Phase III studies. Second, routinely performed urine cytology is characterized by high specificity but low sensitivity. Today, several urine tests are available that may increase diagnostic accuracy and potentially prolong intervals of follow-up cystocopy. Owing to rather high recurrence rates after transurethral tumor resection in most tumors and high progression rates in poorly differentiated tumors, adjuvant intravesical chemotherapy or intravesical immunotherapy has gained widespread use in patients with nonmuscle-invasive bladder cancer. Only a few further immunomodulatory drugs, such as recombinant cytokines, have shown significant clinical effectiveness. Additional approaches, such as photodynamic therapy with different photosensitizers and thermotherapy in combination with intravesical chemotherapy, have been evaluated in Phase III studies.

Abstract
Upregulation of sphingosine kinase 1 (SPHK1) protein has been reported to be associated with a poor prognosis in a variety of malignant tumors. However, the role of SPHK1 in bladder cancer (BC) has not been thoroughly elucidated. The purpose of this study was to assess SPHK1 expression and to explore its contribution to BC. Real-time quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR) was conducted to detect SPHK1 mRNA expression in 37 pairs of fresh-frozen BC tissues and corresponding noncancerous tissues. Results showed that SPHK1 mRNA expression level in BC tissues was significantly higher than that in corresponding noncancerous tissues. To investigate the association between SPHK1 protein expression and clinicopathological characteristics of BC, immunohistochemistry (IHC) was performed in 153 archived paraffin-embedded BC samples. Interestingly, high SPHK1 expression was significantly associated with histologic grade (P = 0.045) and tumor stage (P < 0.001) of patients with BC. The Kaplan-Meier survival curve showed that patients with high SPHK1 expression had significantly reduced overall 5-year survival rates (P < 0.001). Multivariate Cox regression analysis further suggested that the increased expression of SPHK1 was an independent poor prognostic factor for this disease. In conclusion, our data offer the convincing evidence for the first time that the increased expression of SPHK1 may be involved in the pathogenesis and progression of BC. SPHK1 might be a potential marker to predict the prognosis in BC.

Abstract
Purpose The deleted in bladder cancer 1 (DBC1) gene is located within chromosome 9 (9q32-33), a chromosomal region that frequently shows loss of heterozygosity in bladder cancer (BC). It is suspected that it acts as a tumor suppressor gene, but its prognostic value remains unclear. The aim of the present study was to investigate the value of DBC1 as a prognostic marker in BC. Materials and Methods The expression of DBC1 was determined by real-time polymerase chain reaction analysis in 344 patients with BC (220 non-muscle-invasive BC [NMIBC] and 124 muscle-invasive BC [MIBC]) and in 34 patients with normal bladder mucosa. The results were compared with clinicopathologic parameters, and the prognostic value of DBC1 was evaluated by Kaplan-Meier analysis and a multivariate Cox regression model. Results DBC1 expression was significantly decreased in patients with MIBC compared with those diagnosed with NMIBC (p=0.010). Patients with aggressive tumor characteristics had lower DBC1 expression levels in NMIBC (each, p<0.05). By multivariate Cox regression analysis, low DBC1 expression was a predictor of progression to MIBC (hazard ratio, 7.104; p=0.013). Kaplan-Meier estimates revealed a significant difference in tumor recurrence, progression to MIBC, and cancer-specific survival depending on the level of DBC1 expression in NMIBC (log-rank test, each, p<0.05). Conclusions The expression of DBC1 was associated with tumor aggressiveness, progression to MIBC, and survival in NMIBC. Our results suggest that DBC1 expression can be a useful prognostic marker for patients with NMIBC.

Abstract
PURPOSE Urothelial cell carcinoma (UCC) rapidly progresses from superficial to muscle-invasive tumors. The key molecules involved in metastatic progression and its early detection require clarification. The present study defines a seminal role of the metastasis-associated gene MDA-9/Syntenin in UCC progression. EXPERIMENTAL DESIGN Expression pattern of MDA-9/Syntenin was examined in 44 primary UCC and the impact of its overexpression and knockdown was examined in multiple cells lines and key findings were validated in primary tumors. RESULTS Significantly higher (P=0.002-0.003) expression of MDA-9/Syntenin was observed in 64% (28 of 44) of primary tumors and an association was evident with stage (P=0.01), grade (P=0.03), and invasion status (P=0.02). MDA-9/Syntenin overexpression in nontumorigenic HUC-1 cells increased proliferation (P=0.0012), invasion (P=0.0001), and EGF receptor (EGFR), AKT, phosphoinositide 3-kinase (PI3K), and c-Src expression. Alteration of β-catenin, E-cadherin, vimentin, claudin-1, ZO-1, and T-cell factor-4 (TCF4) expression was also observed. MDA-9/Syntenin knockdown in three UCC cell lines reversed phenotypic and molecular changes observed in the HUC-1 cells and reduced in vivo metastasis. Key molecular changes observed in the cell lines were confirmed in primary tumors. A physical interaction and colocalization of MDA-9/Syntenin and EGFR was evident in UCC cell lines and primary tumors. A logistic regression model analysis revealed a significant correlation between MDA-9/Syntenin:EGFR and MDA-9/Syntenin:AKT expressions with stage (P=0.04, EGFR; P=0.01, AKT). A correlation between MDA-9/Syntenin:β-catenin coexpression with stage (P=0.03) and invasion (P=0.04) was also evident. CONCLUSIONS Our findings indicate that MDA-9/Syntenin might provide an attractive target for developing detection, monitoring, and therapeutic strategies for managing UCC.

Abstract
BACKGROUND We investigated whether genetic polymorphisms in the glutathione S transferase mu (GSTM1) and theta (GSTT1) genes modulated risk, disease progression and survival in primary muscle invasive bladder cancer (MIBC). METHODS GSTM1 and GSTT1 polymorphisms were analysed by multiplex polymerase chain reaction (PCR) using blood genomic DNA in 110 MIBC patients and 220 gender- and age-matched healthy controls. The influence of the genetic polymorphisms on patient survival was evaluated by Kaplan-Meier survival curves and Cox Proportional Hazard models. We also evaluated whether cigarette smoking and treatment modality modified the association between genotype and prognosis. RESULTS GSTM1-null individuals exhibited increased risk for MIBC and an association with cigarette smoking. GSTT1-null subjects showed significant disease progression and cancer-specific death. In the combined analysis, GSTT1-null genotype was an independent risk factor for disease progression and cancer specific death regardless of GSTM1 genotype. Significant differences in progression-free survival (PFS) and cancer-specific survival (CSS) were seen based on GSTT1 genotype. The survival impact of the GSTT1 genotype was only valid for smokers. The GSTT1-null genotype was an independent prognostic factor for shorter PFS in patients who received chemotherapy and those who did not undergo radical cystectomy. By multivariate Cox regression analysis, GSTT1-null genotype was a predictive factor for disease progression and cancer specific survival regardless of treatment modality. CONCLUSIONS The GSTM1-null genotype plays an important role in genetic susceptibility to MIBC and the GSTT1-null genotype is associated with disease progression and shorter survival in MIBC.

Abstract
PURPOSE To assess efficacy of Ki67 combined with VEGF as a molecular grading model to predict outcomes with non-muscle invasive bladder cancer (NMIBC). MATERIALS 72 NMIBC patients who underwent transurethral resection (TUR) followed by routine intravesical instillations were retrospectively analyzed in this study. Univariate and multivariate analyses were performed to confirm the prognostic values of the Ki67 labeling index (LI) and VEGF scoring for tumor recurrence and progression. RESULTS The novel molecular grading model for NMIBC contained three molecular grades including mG1 (Ki67 LI≤25%, VEGF scoring≤8), mG2 (Ki67 LI>25%, VEGF scoring≤8; or Ki67 LI≤25%, VEGF scoring>8), and mG3 (Ki67 LI>25%, VEGF scoring>8), which can indicate favorable, intermediate and poor prognosis, respectively. CONCLUSIONS The described novel molecular grading model utilizing Ki67 LI and VEGF scoring is helpful to effectively and accurately predict outcomes and optimize personal therapy.

Abstract
Purpose To validate whether FAM70B, which was found in our micro-array profiling as a prognostic marker for cancer survival, could accurately predict prognosis in patients with muscle-invasive bladder cancer (MIBC). Materials and Methods A total of 124 patients with MIBC were enrolled in this study. The FAM70B expression level was analyzed by real-time polymerase chain reaction by using RNA from tumor tissues. The prognostic effect of FAM70B was evaluated by Kaplan-Meier analysis and a multivariate Cox regression model. Results Kaplan-Meier estimates showed a significant difference in progression-free survival (log-rank test, p=0.011) and cancer-specific survival (log-rank test, p=0.017) according to FAM70B gene expression level. By multivariate Cox regression analysis, high FAM70B expression was predictive of cancer progression (hazard ratio [HR], 2.115, p=0.013) and cancer-specific death (HR, 1.925; p=0.033). In the subgroup analysis, high expression of FAM70B was associated with poor cancer-specific survival, progression-free survival, and overall survival in the patients who underwent cystectomy (log-rank test, p=0.013, p=0.036, p=0.005, respectively). In the chemotherapy group, FAM70B expression was associated with cancer-specific survival and progression-free survival (log-rank test, p=0.013, p=0.042, respectively). Moreover, high FAM70B expression was associated with shorter cancer-specific survival in localized or locally advanced tumor stages (log-rank test, p=0.016). Conclusions We confirmed the significance of FAM70B as a prognostic marker in a validation cohort. Therefore, we propose that the FAM70B gene could be used to more precisely predict cancer progression and cancer-specific death in patients with MIBC.

Abstract
The object of the present study was to identify markers for predicting urinary bladder cancer progression by comparative proteome analysis of bladder cancers and paired normal mucosas. We found that DDX39 was overexpressed in four of six bladder cancers examined compared with respective control tissues. Immunohistochemical analysis using 303 bladder cancer specimens revealed that DDX39 was inversely correlated to pT stage and histological grade progression. The incidence of DDX39(high) tumors (positive cells ≥50%) was 68.6%, 43.5%, 20.0%, and 5.3% in pTa, pT1, pTis, and ≥pT2 tumors, respectively, and 65.2%, 60.7%, and 19.6% in G1, G2, and G3 tumors, respectively. The incidence of DDX39(high) tumors was significantly lower in pT1 and ≥pT2 compared to pTa tumors, and also significantly lower in G3 compared to G1 and G2 tumors. Follow-up analysis (n = 105) revealed that DDX39(low) tumors (positive cells <50%) were associated with disease progression (hazard ratio 7.485; P = 0.0083). Furthermore, DDX39-knockdown bladder cancer cells increased their invasion ability compared to negative control cells. These results suggest that DDX39 is a suppressor of invasion and loss of its function predicts disease progression in bladder cancers.

Abstract
Background Current urine-based assays for bladder cancer (BCa) diagnosis lack accuracy, so the search for improved biomarkers continues. Through genomic and proteomic profiling of urine, we have identified a panel of biomarkers associated with the presence of BCa. In this study, we evaluated the utility of three of these biomarkers, interleukin 8 (IL-8), Matrix metallopeptidase 9 (MMP-9) and Syndecan in the diagnosis of BCa through urinalysis. Methods Voided urines from 127 subjects, cancer subjects (n = 64), non-cancer subjects (n = 63) were analyzed. The protein concentrations of IL-8, MMP-9, and Syndecan were assessed by enzyme-linked immunosorbent assay (ELISA). Data were also compared to a commercial ELISA-based BCa detection assay (BTA-Trak©) and urinary cytology. We used the area under the curve of a receiver operating characteristic (AUROC) to compare the performance of each biomarker. Results Urinary protein concentrations of IL-8, MMP-9 and BTA were significantly elevated in BCa subjects. Of the experimental markers compared to BTA-Trak©, IL-8 was the most prominent marker (AUC; 0.79; 95% confidence interval [CI], 0.72-0.86). Multivariate regression analysis revealed that only IL-8 (OR; 1.51; 95% CI, 1.16-1.97, p = 0.002) was an independent factor for the detection of BCa. Conclusions These results suggest that the measurement of IL-8 in voided urinary samples may have utility for urine-based detection of BCa. These findings need to be confirmed in a larger, prospective cohort.

Performance of survivin mRNA as a biomarker for bladder cancer in the prospective study UroScreen. PLoS One 2012; 7:e35363.

Abstract
Background Urinary biomarkers have the potential to improve the early detection of bladder cancer. Most of the various known markers, however, have only been evaluated in studies with cross-sectional design. For proper validation a longitudinal design would be preferable. We used the prospective study UroScreen to evaluate survivin, a potential biomarker that has multiple functions in carcinogenesis. Methods/Results Survivin was analyzed in 5,716 urine samples from 1,540 chemical workers previously exposed to aromatic amines. The workers participated in a surveillance program with yearly examinations between 2003 and 2010. RNA was extracted from urinary cells and survivin was determined by Real-Time PCR. During the study, 19 bladder tumors were detected. Multivariate generalized estimation equation (GEE) models showed that β-actin, representing RNA yield and quality, had the strongest influence on survivin positivity. Inflammation, hematuria and smoking did not confound the results. Survivin had a sensitivity of 21.1% for all and 36.4% for high-grade tumors. Specificity was 97.5%, the positive predictive value (PPV) 9.5%, and the negative predictive value (NPV) 99.0%. Conclusions In this prospective and so far largest study on survivin, the marker showed a good NPV and specificity but a low PPV and sensitivity. This was partly due to the low number of cases, which limits the validity of the results. Compliance, urine quality, problems with the assay, and mRNA stability influenced the performance of survivin. However, most issues could be addressed with a more reliable assay in the future. One important finding is that survivin was not influenced by confounders like inflammation and exhibited a relatively low number of false-positives. Therefore, despite the low sensitivity, survivin may still be considered as a component of a multimarker panel.

Abstract
UNLABELLED What's known on the subject? and What does the study add? The prognosis of bladder cancer significantly depends on tumour stage and time of diagnosis so early diagnosis is desirable to decrease mortality and treatment costs. The NMP22 test is approved for clinical application by the Food and Drug Administration (FDA) of the US. Previous studies have reported values of 47-100% for sensitivity and 58-91% for specificity with this test, but there is no new data on the predictive value of NMP22 for screening bladder cancer (BC). The most important risk factor for BC is the tobacco consumption but occupational exposure to carcinogenic substances, especially aromatic amines, is regarded as another risk factor. The UroScreen study is a prospective longitudinal study for the early detection of BC. To our knowledge, it is the largest prospective validation study conducted over the longest period of time. The study results led us to conclude that, based on the currently available data, NMP22 should not be regarded as an alternative to endoscopy, and we could not make a general recommendation for screening or follow-up. The UroScreen results indicate that urine-based molecular markers could be a suitable addition to urine cytology and the detection of microhaematuria. OBJECTIVE To evaluate the value of nuclear matrix protein-22 (NMP22) in bladder cancer (BC) screening, and its effect on variables in a prospective study in a high-risk population. PATIENTS AND METHODS A total of 1772 chemical workers (mean age 62 years) exposed to carcinogenic aromatic amines were enrolled in the study. In all, 7091 screening check-ups in 1609 subjects were performed. Urine samples were collected for a quantitative NMP22 immunoassay, urine analysis and creatinine concentration assessment. Cystoscopy and subsequent transurethral resection were performed where there were suspicious findings. RESULTS Histopathological analysis found three papillary urothelial neoplasms of low malignant potential, five recurrent BCs and 13 primary BCs. Three tumours were at a muscle-invasive stage (pT2, pT3a or pT3b). We found higher NMP22 concentrations (>10 U/mL) in 224 patients, which correctly predicted BC in six cases (sensitivity 97.29%, specificity 28.57%; negative predictive value 99.04%, positive predictive value 12.24%). Gross haematuria affected NMP22 results (odd ratio [OR] 3.49, 95% confidence interval [CI] 1.81-6.73). Infection also affected NMP22 results (OR 4.13, 95% CI 2.31-7.35). NMP22 was more frequently positive in urine with creatinine concentration >2.5 g/L (OR 1.61, 95% CI 0.91-2.86). CONCLUSIONS NMP22 outcomes are affected by haematuria, infection and concentrated urine. NMP22 alone cannot be recommended for primary screening in a high-risk population nor as an alternative to cystoscopy during follow-up. A NMP22 test might be a useful adjunct to urine cytology.
