An up-to-date catalog of available urinary biomarkers for the surveillance of non-muscle invasive bladder cancer. World J Urol 2018; 36:1981-1995. [PMID: 29931526 PMCID: PMC6280823 DOI: 10.1007/s00345-018-2380-x] [Citation(s) in RCA: 78] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2018] [Accepted: 06/15/2018] [Indexed: 02/06/2023] Open
Abstract
OBJECTIVES With the advent of novel genomic and transcriptomic technologies, new urinary biomarkers have been identified and tested for bladder cancer (BCa) surveillance. To summarize the current status of urinary biomarkers for the detection of recurrence and/or progression in the follow-up of non-muscle invasive BCa patients, and to assess the value of urinary biomarkers in predicting response to intravesical Bacillus Calmette-Guerin (BCG) therapy. METHODS AND MATERIALS A medline/pubmed© literature search was performed. The performance of commercially available and investigational biomarkers has been reviewed. End points were cancer detection (recurrence), cancer progression, and response to BCG therapy. RESULTS The performance requirements for biomarkers are variable according to the clinical scenario. The clinical role of urinary biomarkers in the follow-up of non-muscle invasive BCa patients remains undefined. The FDA-approved tests provide unsatisfactory sensitivity and specificity levels and their use is limited. Fluorescence in situ hybridization (FISH) has been shown to be useful in specific scenarios, mostly as a reflex test and in the setting of equivocal urinary cytology. FISH and immunocytology could conceivably be used to assess BCG response. Recently developed biomarkers have shown promising results; upcoming large trials will test their utility in specific clinical scenarios in a manner similar to a phased drug development strategy. CONCLUSIONS Current commercially available urinary biomarker-based tests are not sufficiently validated to be widely used in clinical practice. Several novel biomarkers are currently under investigation. Prospective multicenter analyses will be needed to establish their clinical relevance and value.

Abstract
Feline idiopathic cystitis (FIC) is the only spontaneous animal model for human interstitial cystitis (IC), as both possess a distinctive chronical and relapsing character. Underlying pathomechanisms of both diseases are not clearly established yet. We recently detected increased urine fibronectin levels in FIC cases. The purpose of this study was to gain further insight into the pathogenesis by assessing interacting partners of fibronectin in urine of FIC affected cats. Several candidate proteins were identified via immunoprecipitation and mass spectrometry. Considerable changes in FIC conditions compared to physiological expression of co-purified proteins were detected by Western blot and immunohistochemistry. Compared to controls, complement C4a and thioredoxin were present in higher levels in urine of FIC patients whereas loss of signal intensity was detected in FIC affected tissue. Galectin-7 was exclusively detected in urine of FIC cats, pointing to an important role of this molecule in FIC pathogenesis. Moderate physiological signal intensity of galectin-7 in transitional epithelium shifted to distinct expression in transitional epithelium under pathophysiological conditions. I-FABP expression was reduced in urine and urinary bladder tissue of FIC cats. Additionally, transduction molecules of thioredoxin, NF-κB p65 and p38 MAPK, were examined. In FIC affected tissue, colocalization of thioredoxin and NF-κB p65 could be demonstrated compared to absent coexpression of thioredoxin and p38 MAPK. These considerable changes in expression level and pattern point to an important role for co-purified proteins of fibronectin and thioredoxin-regulated signal transduction pathways in FIC pathogenesis. These results could provide a promising starting point for novel therapeutic approaches in the future.

Abstract
OBJECTIVE Upper urinary tract urothelial cell carcinomas (UUT-UCCs) are rare but usually invasive at diagnosis. Early diagnosis of UUT-UCCs is thus warranted. UUT has the same embryological origin with bladder and BLCA-4 is a highly sensitive and specific marker for bladder cancer. We intend to investigate the viability of BLCA-4 in detecting UUT-UCCs. MATERIAL AND METHODS Urines from 30 UUT-UCC patients, 10 ureteral polyp patients, 20 infected patients with incarcerated ureteral stones, and 30 normal controls were included. BLCA-4 antibody was produced and applied in an indirect ELISA assay. RESULTS Urinary BLCA-4 is significantly higher in UUT-UCC group than «Polyp» group (P=0.0017), «Infection» group (P<0.0001), or « Normal» group (P<0.0001). The «Polyp» group is also higher than «Infection» group (P=0.015), or «Normal» group (P=0.0009). ROC curve revealed at cut-off of 5.5×10(-4)A, sensitivity was 93.3% and specificity was 100%. When grouped as ureteral mass vs normal, same cut-off value yielded 93.3% sensitivity and 83.3% specificity. At 2.4×10(-4)A, sensitivity was 56.7% and specificity was 97.2%. CONCLUSIONS Urinary BLCA-4 is also highly specific in UUT-UCCs detection. For incidentally identified ureteral mass, BLCA-4 can be considered an auxiliary indicator besides biopsy.

Distinct patterns and behaviour of urothelial carcinoma with respect to anatomical location: how molecular biomarkers can augment clinico-pathological predictors in upper urinary tract tumours. World J Urol 2012; 31:21-9. [PMID: 22986906 DOI: 10.1007/s00345-012-0946-6] [Citation(s) in RCA: 51] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2012] [Accepted: 09/07/2012] [Indexed: 01/04/2023] Open
Abstract
PURPOSE Upper urinary tract urothelial carcinoma (UTUC) shares many similarities with bladder-UC, but there is strong evidence on a clinical, aetiological, epidemiological and genetic level that key differences exist. In this review, we aim to highlight how UTUC differs from bladder-UC and report on the utility of molecular markers in the diagnosis and management of UTUC. MATERIALS AND METHODS A systematic literature search was conducted using the Medline and Embase databases and specific keyword combinations: 'urothelial carcinoma', 'bladder cancer', 'transitional cell carcinoma', 'upper tract', 'upper urinary tract', 'genetics', 'prognosis' and 'biomarkers'. RESULTS UTUC has specific acquired (e.g. Balkans nephropathy, phenacetin abuse) and genetic hereditary non-polyposis colorectal cancer risk factors compared with bladder-UC. In general, the molecular biology of UC is broadly similar, irrespective of location in the urinary tract. However, there are distinct genetic (microsatellite instability) and epigenetic (hypermethylation) differences between some UTUC and bladder-UC. Clinical-pathological variables (e.g. hydronephrosis, tumour architecture, tumour location, stage and grade) have independent predictive power in UTUC, but tissue and urinary biomarkers can improve the clinical prediction of recurrence, invasion and survival in UTUC, though the evidence level is weak. CONCLUSIONS UTUC shares many similarities with bladder-UC, but there is strong evidence that they should be considered as distinct urothelial entities. Prospective multi-institutional studies investigating molecular markers are urgently needed to augment clinic-pathological predictors in UTUC.

Abstract
Hereditary nonpolyposis colorectal cancer, or Lynch syndrome, is responsible for 2-3% of all colorectal cancers. Lynch syndrome is also associated with a high risk of extracolonic cancers, including endometrial, stomach, small bowel, pancreas, biliary tract, ovary, urinary tract, brain, and skin cancer. In this Review, we discuss the risks, surveillance tests, and guidelines for the management of extracolonic tumours associated with Lynch syndrome. For all types of extracolonic cancer, evidence supporting surveillance is scarce. A benefit of surveillance is evident only for endometrial cancer, where transvaginal ultrasound and endometrial sampling detect tumours in early stages. Surveillance is generally recommended for urinary tract and gastric cancer, especially in families with more than one member with these types of cancer. For the other types of cancer, surveillance is typically not recommended. Prophylactic hysterectomy and bilateral salpingo-oophorectomy should be considered for women with Lynch syndrome who are past childbearing age, especially during surgery for colorectal cancer. No data show efficacy of chemopreventive drugs in reducing the risk of extracolonic cancers for patients with Lynch syndrome.
