Abstract
Despite advances in the surgical and medical treatment of bladder cancer, there have only been minor improvements in mortality and morbidity rates over the past decades. Urine-based markers help to improve diagnosing bladder cancer with the aim of complementing or probably in future replacing cystoscopy. Biomarkers may allow individualized risk stratification and support decision-making regarding therapy and follow-up. This review summarizes the existing urine-based biomarkers in bladder cancer. We conducted a comprehensive review of the literature. We conducted a PubMed/Medline based research on English language articles and selected original articles and review articles that provided both description and assessment of urinary markers at time of screening, initial diagnosis, monitoring and prognostic evaluation of urothelial bladder cancer. Our research covered studies published between 2000 and 2017. The aim of this study was to give clinicians keys to understand the existing or promising urinary markers that may become alternatives to cytology/cystoscopy pair in the near future. Many urinary markers are now available, often with superior sensitivity to cytology. Their uses have been evaluated in numerous clinical situations in addition to the time of initial diagnosis and surveillance such as cases of isolated macroscopic hematuria or atypical cytology discordant with the rest of the explorations. However, their superiority over the cytology/cystoscopy association is not demonstrated. These new markers are lacking for the most part of standardization and simplicity making their use in common practice difficult. the types and forms of these new markers are very heterogeneous among themselves and between the studies that evaluate them. Well-designed protocols and prospective, controlled trials are needed to provide the basis to determine whether integration of urine- and blood-based biomarkers into clinical decision-making will be of value for bladder cancer detection and screening in the future.

Abstract
PURPOSE Urinary cytology (C) and cystoscopy remain the gold standard for the detection and screening of bladder cancer (BC). In this prospective study, we analyzed whether baseline C, ImmunoCyt (I), BTA Stat (B), hemoglobin dipstick (H), and NMP22 BladderChek (N) can predict recurrence and progression. METHODS Urinary samples from 91 patients with BC were prospectively collected over an 18-month period. Baseline characteristics of the population included patient demographics, various clinicopathological variables and use of intravesical therapy. Progression and recurrence were then assessed after a median follow-up of 48 months (IQR 23.7-59.5). Univariate and multivariate analyses were performed using COX proportional hazards models. RESULTS On univariate analysis, C (HR 1.36; p = 0.26), I (HR 0.89; p = 0.66), B (HR 0.80; p = 0.42), H (HR 0.75; p = 0.30), and N (HR 0.82; p = 0.48) were not associated with recurrence-free survival (RFS). With regard to progression-free survival (PFS), C was significantly prognostic (HR 2.67; p = 0.017), whereas I, B, H, and N were not. On multivariable analysis, NMP22 was the only marker to be independently associated with RFS (HR 0.41, p < 0.01) and PFS (HR 0.32, p = 0.02). CONCLUSION Based on the results of this study, baseline C, B, I, and H were not independently prognostic. Prognostic impact of NMP22 requires further validation in a multicenter larger study.

Abstract
INTRODUCTION Bladder augmentation is widely used to treat otherwise unmanageable urinary incontinence. However, it is associated with a large number of complications, of which tumor formation is the most severe. Mucin proteins and MUC genes are linked, among others, to malignancies of the urinary bladder and the gastrointestinal system. OBJECTIVE To investigate histological alterations as well as changes in expression of MUC1 and MUC2 genes and proteins following different types of urinary bladder augmentation or substitution performed in children and adolescents. PATIENTS AND METHODS Between 1988 and 2013, 91 patients underwent urinary bladder augmentation or substitution at the study institute. Patients were included on whom cystoplasty had been performed 4 years previously or earlier, and could have been followed-up prospectively. Thus, 54 patients were involved in the study. In eight patients gastrocystoplasty was performed, in 17 patients ileocystoplasty, and in 22 patients colocystoplasty. Seven patients underwent bladder substitution using a colonic-segment. Biopsies were taken via cystoscopy from the native bladder, from the gastrointestinal segment used for augmentation, and from the anastomotic line between these two. One part of the samples was fixed in formaldehyde for routine histological processing. The other part of the biopsies was embedded into OCT medium, then cryosectioned and fluorescently double-immunostained for MUC1 and MUC2 proteins. Samples from the microscopically dysplastic lesions and from the 15-year-old or older biopsies were processed by laser capture microdissection, and then real-time PCR was done. Data were statistically analyzed by ANOVA and ordinary least squares regression tests. RESULTS One adenocarcinoma was found in a female patient, 11 years after colocystoplasty. There were no significant changes in the level of MUC1 and MUC2 proteins and gene expression in the urothelium and in the gastrointestinal segment used for augmentation following ileocystoplasty and gastrocystoplasty. Significant increase in MUC1 and decrease in MUC2 protein levels were detected following colocystoplasty in the large bowel segment used for augmentation, both with qualitative and quantitative methods (p < 0.05) (Figure). The uroepithelium showed no significant change. RT-PCR revealed progressive increase in MUC1 gene expression and decrease in MUC2 gene expression after colocystoplasty in the course of time. It also showed highly increased MUC1 gene expression and decreased MUC2 gene expression in the samples of patients. CONCLUSIONS Alterations in gene expression of MUC1 and MUC2 might serve as promising markers for early detection of histological changes after colocystoplasty.

Abstract
AIM To determine whether pioglitazone is associated with an increased risk of bladder cancer among Indian type 2 diabetic patients. METHODS A retrospective data analysis of 2222 type 2 diabetic patients was conducted. The study subjects were divided into two equal groups: 1111 pioglitazone users and 1111 pioglitazone non-users. The safety of pioglitazone therapy was analyzed in terms of occurrence of bladder and other types of cancers along with its efficacy in terms of glycemic control. Parameters for assessing safety were duration of disease, duration of usage and total dose of pioglitazone consumed across age groups, glycemic control, obesity and family history of any cancer. Bladder cancer prevalence was analyzed on the basis of urinary cytology, urine routine and microscopy, hematuria, urinary nuclear matrix protein 22 analysis and ultrasonography. RESULTS Of the 2222 cases analysed, there was no evidence of bladder cancer in any of the studied groups, (p=not significant) which was also evident among 1111 patients on Pioglitazone therapy with a cumulative dose consumption of 2737 mg to 1,31,400 mg. On subgroup analysis, there was no evidence of bladder cancer amongst patients with age >60 years, duration of diabetes > 10 years and uncontrolled diabetics (HbA1c >8%) with cumulative pioglitazone consumption of >28,000 mg. A significant number of patients achieved good glycemic control (HbA1c <7.5%) with pioglitazone therapy. CONCLUSION Pioglitazone therapy was not associated with occurrence of bladder cancer among Indian type 2 diabetic patients and demonstrated good glycemic control.

Abstract
INTRODUCTION Diagnosis and follow-up of bladder cancer is based on cytology and cystoscopic exams. Cytology is highly specific but remains with a highly variable sensitivity. Cystoscopy is an invasive exam and has shown specific limits. Urinary test, highly specific and highly sensitive, might be ideal to replace the couple cytology-cystoscopy. MATERIAL AND METHODS Through a literature review, using MeSH system and Pubmed system (keywords: NMP22 and bladder cancer), authors pointed to the value of NMP22 to replace cystoscopy and cytology. RESULTS Between 1996 and 2010, 193 publications were identified with these keywords. Seventeen original articles have been selected based on their quality and methodology. NMP22 was more sensitive than cytology for follow-up and screening of bladder cancer. As screening test, NMP22 has shown positive predictive value between 0 and 70%. As follow-up test, NMP22 has shown more stable positive predictive value close to 70%. Coupled to cytology, NMP22 has shown predictive positive value up to 90%. CONCLUSION For screening test, NMP22 should be the referent test for best selection cases (tobacco, hematuria) and for systemic elimination of false positive cases (ureteral stent, lithiasis). For follow-up test, NMP22-cytology should be the new reference. Moreover, when NMP22 is positive with negative cystoscopy, follow-up may be carefully proposed (recurrence risk×10).

Abstract
BACKGROUND Cystoscopy with urinary cytology is the gold standard for the diagnosis and follow-up of patients with tumors of the urinary bladder. The aim of the study was to evaluate the performance of the nuclear matrix protein 22 (NMP22) tumor marker test, BladderChek® point-of-care test and voided urinary cytology for the detection and follow-up of bladder tumors. METHODS NMP22 was measured using an ELISA assay in stabilized voided urine and using the BladderChek® test. Voided urinary cytology was performed on urine samples. Results were compared to cystoscopic findings and histopathological examination results after transurethral resection of the bladder lesion. RESULTS For the prediction of malignant histopathological result, sensitivity and specificity were 45.2% and 75.0%, respectively, for NMP22 at a cut-off of 7.5 kU/L, 17.7% and 100% for the BladderChek® test and 37.0% and 100% for voided urine cytology. For the prediction of suspicious or positive cystoscopic finding, sensitivity and specificity were 40.4% and 72.1%, respectively, for NMP22 at a cut-off of 7.5 kU/L, 14.8% and 93.8% for the BladderChek® test and 26.8% and 98.1% for voided urine cytology. CONCLUSIONS The NMP22 quantitative test showed higher sensitivity and lower specificity compared with voided urine cytology, whereas the sensitivity of the BladderChek® test was low. We could not recommend any of the three non-invasive tests as a replacement for cystoscopy for the diagnosis or follow-up of urinary bladder tumors.

Abstract
A biomarker is a characteristic that is objectively measured and evaluated as an indicator of normal biologic processes, pathogenic processes, or pharmacologic responses to a therapeutic intervention. In cancer, a biomarker refers to a substance or process that is indicative of the presence of cancer in the body. A biomarker might be either a molecule secreted by a tumor or it can be a specific response of the body to the presence of cancer. Genetic, epigenetic, proteomic, glycomic, and imaging biomarkers can be used for cancer diagnosis, prognosis and epidemiology. These markers can be assayed in non-invasively collected biofluids. However, few cancer biomarkers are highly sensitive and specific for cancer detection at the present time. Consequently, biomarkers are not yet ready for routine use due to challenges in their clinical validation for early disease detection, diagnosis and monitoring to improve long-term survival of patients.
