Abstract
OBJECTIVES Clinicopathologic features and recurrence rates of inverted noninvasive urothelial papillary tumors have been poorly characterized to date with few larger studies evaluating long-term outcomes. The spectrum of histomorphology, clinical features, and prognosis of inverted lesions of the urinary bladder are retrospectively reviewed. METHODS Archived paraffin-embedded urothelial tumor samples from patients diagnosed with inverted urothelial papillary lesions between January 2005 and June 2020 were collated. A matched control population of patients with exophytic papillary lesions of the urothelium diagnosed during the same time period was randomly selected. The conventional clinicopathologic features of inverted urothelial papillary tumor were evaluated retrospectively and patient demographics, tumor characteristics, recurrence, and survival information were recorded. RESULTS Lower recurrence rates were observed for inverted papillary urothelial neoplasm of low malignant potential (IPUNLMP) relative to papillary urothelial neoplasms of low malignant potential and for low-grade papillary urothelial carcinoma with an inverted growth pattern (LG-PUCI) relative to low-grade papillary urothelial carcinomas. No recurrence was found among the inverted urothelial papilloma cases. The 2- and 5-year disease-free survival rates were 100.0% and 85.2% for IPUNLMP patients; 94.4% and 80.4% for papillary urothelial neoplasms of low malignant potential; 89.5% and 82.0% for LG-PUCI; 73.7% and 54.6% for low-grade papillary urothelial carcinoma; 40.0% and 20.0% for high-grade papillary urothelial carcinoma with an inverted growth pattern patients and 26.7% and 26.7% for high-grade papillary urothelial carcinoma. Multivariate Cox regression analysis of IPUNLMP and LG-PUCI/high-grade papillary urothelial carcinoma with an inverted growth pattern indicated that tumor number (hazard ratio=4.356; 95% CI: 1.145-16.570; P =0.031) was a powerful prognostic factor for disease-free survival. CONCLUSION Noninvasive, papillary urothelial lesions of the bladder tend to have lower recurrence and a better outcome if an inverted growth pattern is shown.

A Randomized Controlled Trial to Study the Rationale of Antibiotic Prophylaxis in Diagnostic Rigid Cystoscopy: A Relook in The Era of Antibiotic Stewardship. Int J Appl Basic Med Res 2021; 11:171-176. [PMID: 34458120 PMCID: PMC8360220 DOI: 10.4103/ijabmr.ijabmr_565_20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2020] [Revised: 11/02/2020] [Accepted: 02/19/2021] [Indexed: 11/04/2022] Open
Abstract
Background In the era of widespread antibiotic (AB) resistance, the role of prophylaxis in diagnostic cystoscopy is controversial. Aim This study aimed to compare the incidence of postcystoscopy positive urinary culture (PC-PUC) and urinary tract infection (UTI) in patients undergoing diagnostic rigid cystoscopy with and without prophylaxis with preprocedural single-dose intravenous AB. Materials and Methods This prospective study was done in patients with preprocedural sterile urine undergoing elective diagnostic rigid cystoscopy. Patients were randomized into two groups, with one group receiving preprocedure single dose of intravenous cefuroxime sodium as prophylaxis half to 1 h before the procedure (Group AB prophylaxis) and the other group receiving no antibiotic prophylaxis (Group NAB). All patients were followed up till 1-month postprocedure, for any symptoms of urinary infection, mandatory urine microscopy and culture at 24-48 h, 1 week and 4 weeks post procedure, and addition sample in case of any urinary symptoms or fever. Results A total of 225 patients were studied, with 110 in AB prophylaxis and 115 in NAB groups. The use of prophylaxis did not decrease the incidence of PC-PUC (8.7%-3.6%; P = 0.167) or UTI (6.1%-1.8%; P = 0.102). Females and diabetics had significantly higher risk of PC-PUC, on univariate and multivariate analysis, not affected by prophylaxis. Conclusion Preprocedural AB prophylaxis does not decrease the incidence of postcystoscopy bacteriuria significantly. Females and diabetics have significantly increased risk, but prophylaxis has no role in them either.

Abstract
CXC chemokine ligand 12 (CXCL12) is an important member of the CXC subfamily of chemokines, and has been extensively studied in various human body organs and systems, both in physiological and clinical states. Ligation of CXCL12 to CXCR4 and CXCR7 as its receptors on peripheral immune cells gives rise to pleiotropic activities. CXCL12 itself is a highly effective chemoattractant which conservatively attracts lymphocytes and monocytes, whereas there exists no evidence to show attraction for neutrophils. CXCL12 regulates inflammation, neo-vascularization, metastasis, and tumor growth, phenomena which are all pivotally involved in cancer development and further metastasis. Generation and secretion of CXCL12 by stromal cells facilitate attraction of cancer cells, acting through its cognate receptor, CXCR4, which is expressed by both hematopoietic and non-hematopoietic tumor cells. CXCR4 stimulates tumor progression by different mechanisms and is required for metastatic spread to organs where CXCL12 is expressed, thereby allowing tumor cells to access cellular niches, such as the marrow, which favor tumor cell survival and proliferation. It has also been demonstrated that CXCL12 binds to another seven-transmembrane G-protein receptor or G-protein-coupled receptor, namely CXCR7. These studies indicated critical roles for CXCR4 and CXCR7 mediation of tumor metastasis in several types of cancers, suggesting their contributions as biomarkers of tumor behavior as well as potential therapeutic targets. Furthermore, CXCL12 itself has the capability to stimulate survival and growth of neoplastic cells in a paracrine fashion. CXCL12 is a supportive chemokine for tumor neovascularization via attracting endothelial cells to the tumor microenvironment. It has been suggested that elevated protein and mRNA levels of CXCL12/CXCR4/CXCR7 are associated with human bladder cancer (BC). Taken together, mounting evidence suggests a role for CXCR4, CXCR7, and their ligand CXCL12 during the genesis of BC and its further development. However, a better understanding is still required before exploring CXCL12/CXCR4/CXCR7 targeting in the clinic.

Abstract
AIMS To evaluate the impact of a histologically inverted pattern on recurrence in patients with newly diagnosed non-invasive, low-grade papillary urothelial carcinoma of the urinary bladder. METHODS A total of 81 patients with primary bladder non-invasive, low-grade papillary urothelial carcinoma diagnosed in a single tertiary-care centre who had at least 1-year follow-up after an initial resection were included. All slides from each case were reviewed to determine the growth pattern (exophytic versus endophytic, i.e. inverted) and other histological parameters. Clinical data were retrieved from hospital records. RESULTS Disease recurrence occurred in 41 (50.6%) patients. Cases with an inverted pattern showed a lower recurrence rate than those with pure exophytic tumours (37.5% versus 52.1%), a longer time to first recurrence (mean 34 versus 21.5 months) and fewer recurrence episodes (p=0.482, 0.564 and 0.051, respectively). All recurring inverted cases recurred only once during follow-up. No tumour with >80% inverted architecture recurred. CONCLUSION Our results suggest that non-invasive, low-grade papillary urothelial carcinoma of the bladder tends to have a better outcome in terms of disease recurrence if it shows an inverted growth pattern. To indicate the presence and percentage of the inverted pattern in low-grade urothelial carcinomas in the pathology report might be considered as an adjunct to help long-term patient management.

Abstract
Urinary tract cancers are common and comprise a gamut of lesions ranging from small benign tumors to aggressive neoplasms with high mortality. The predominant urinary tract malignancy is bladder cancer. The clinical challenge is early detection and adequate follow-up because recurrence is high and delayed diagnosis is associated with poor prognosis. Primary care physicians form a key part of the management apparatus for these patients and may be responsible for ensuring adequate ongoing surveillance. This article aims to outline the evaluation of patients in whom urinary tract cancer is suspected and briefly review the general principles of treatment.

Abstract
Bladder cancer (BCa) is a common malignancy worldwide and has a high probability of recurrence after initial diagnosis and treatment. As a result, recurrent surveillance, primarily involving repeated cystoscopies, is a critical component of post diagnosis patient management. Since cystoscopy is invasive, expensive and a possible deterrent to patient compliance with regular follow-up screening, new non-invasive technologies to aid in the detection of recurrent and/or primary bladder cancer are strongly needed. In this study, mass spectrometry based metabolomics was employed to identify biochemical signatures in human urine that differentiate bladder cancer from non-cancer controls. Over 1000 distinct compounds were measured including 587 named compounds of known chemical identity. Initial biomarker identification was conducted using a 332 subject sample set of retrospective urine samples (cohort 1), which included 66 BCa positive samples. A set of 25 candidate biomarkers was selected based on statistical significance, fold difference and metabolic pathway coverage. The 25 candidate biomarkers were tested against an independent urine sample set (cohort 2) using random forest analysis, with palmitoyl sphingomyelin, lactate, adenosine and succinate providing the strongest predictive power for differentiating cohort 2 cancer from non-cancer urines. Cohort 2 metabolite profiling revealed additional metabolites, including arachidonate, that were higher in cohort 2 cancer vs. non-cancer controls, but were below quantitation limits in the cohort 1 profiling. Metabolites related to lipid metabolism may be especially interesting biomarkers. The results suggest that urine metabolites may provide a much needed non-invasive adjunct diagnostic to cystoscopy for detection of bladder cancer and recurrent disease management.

Abstract
Background Non Muscle Invasive Bladder Transitional Cancer (NMIBC) and Muscle Invasive Bladder Transitional Cancer (MIBC)/invasive have different gene profile and clinical course. NMIBC prognosis is not completely predictable, since the relapse rate is higher than 20%, even in the form of MIBC. The aim of this study is to evaluate if UTR expression can discriminate between NMIBC and MIBC and predict the risk of relapses in NMIBCs. Methods We have investigated upon urotensin-II (UII) receptor (UTR) expression in vivo in 159 patients affected by NMIBC. The biological role of UTR was also investigated in vitro. UTR expression was evaluated in a tissue-micro-array, consisting of normal, NMIBC and invasive bTCC samples. Results UTR discriminated between NMIBC and MIBC and showed a significant correlation between low UTR expression and shorter disease free survival in NMIBC. The superagonist UPG84 induced growth suppression at nM concentrations on 3/4 cell lines. Bladder cancer cell treatment with the antagonist urantide or the knock-down of UTR with a specific shRNA significantly blocked both the motility and invasion of bladder cancer cells. Conclusions The evaluation of UTR expression can discriminate between NMIBC at high and low risk of relapse. Moreover, our data suggest that UTR is involved in the regulation of motility, invasion and proliferation of bladder cancer cells. High UTR expression is an independent prognostic factor of good prognosis for NMIBC regulating motility and invasion of bladder cancer cells.

Abstract
UNLABELLED WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Recurrence and progression prediction in urothelial cancer is currently based on clinical and pathological factors: tumour grade, tumour stage, number of lesions, tumour size, previous recurrence rate, and presence of concomitant carcinoma in situ. These factors are not specific enough to predict progression and ∼50% of patients diagnosed as high risk in fact do not progress within 3 years. Patient follow-up is both expensive and unpleasant (frequent invasive cystoscopies). Molecular biomarkers, including microRNAs have been studied to provide additional prognostic information for these patients, but to date no molecular biomarker has become the 'gold standard' for patient diagnosis and follow-up. We used Rosetta Genomics' highly specific microRNA expression profiling platforms to study the prognostic role of microRNAs in bladder cancer. Using microdissection we chose specific tumour microRNAs to study in order to avoid background contamination. Tumour progression was associated with altered levels of microRNAs. In particular, high expression levels of miR-29c* were associated with a good prognosis. The study found that the use of microRNAs for determining progression and invasiveness for patients with urothelial cancer could potentially have a substantial impact on the treatment and follow-up individual patients. OBJECTIVE To identify microRNAs that could be useful as prognostic markers for non-muscle-invasive (NMI) bladder carcinoma. PATIENTS AND METHODS Formalin-fixed, paraffin-embedded samples of 108 NMI bladder carcinomas, and 29 carcinomas invading bladder muscle were collected, and microRNA expression levels were measured using microarrays. For 19 samples, microdissection was performed to compare microRNA expression between the tumour and surrounding tissue. MicroRNAs that were found to be unrelated to the tumour itself were excluded as potential prognostic markers. RESULTS Expression profiles identified microRNAs that were differentially expressed in NMI tumours from patients who later progressed to carcinoma invading bladder muscle compared with NMI tumours from patients that did not progress. The microRNA profile of tumours invading the bladder muscle was more similar to that of NMI tumours from patients who later progressed, than to that of the same-stage NMI tumours from patients who did not later progress. The expression level of one microRNA, miR-29c*, was significantly under-expressed in tumours that progressed and could be used to stratify patients with T1 disease into risk groups. CONCLUSIONS MicroRNAs can be useful biomarkers for prognosis in patients with urothelial carcinoma. In our study, expression levels of several microRNAs, including miR-29c* identified high- and low-risk groups. These biomarkers show promise for the stratification of patients with bladder cancer.

Abstract
Numerous studies have suggested that interleukin 11 (IL-11) has roles in human gastric, prostate and bone cancer and endometrial carcinoma. Hence, we evaluated the expression of IL-11 in bladder cancer and the correlation of IL-11 levels and clinico-pathological features. The expression of IL-11 in primary human bladder cell culture, human bladder cancer cell lines, transitional cell carcinoma (TCC) and non-cancerous bladder tissues (NATs) were analyzed by western blotting. Enzyme-linked immunosorbent assay (ELISA) for urinary IL-11 was performed to compare the IL-11 levels in healthy subjects and subjects diagnosed with bladder cancer. Our study suggested that the expression of IL-11 in human bladder cancer cell lines and TCC was downregulated compared with primary human bladder cell culture and matched NATs. We also demonstrated reduced urinary levels of IL-11 in subjects with bladder cancer compared with healthy subjects. Furthermore, we revealed that the levels of IL-11 were associated with tumor grade and stage. The results suggested that reduced levels of IL-11 may play an important role in the carcinogenesis and progression of TCC. They also indicated that IL-11 may be a promising predictor for prognosis of TCC.

Abstract
UNLABELLED WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Bladder cancer patients with lamina propria invasion (T1 disease) and residual T1 disease on restaging transurethral resection of bladder tumour (re-TURBT) are at a very high risk for recurrence and progression. Despite this risk, most patients are treated with a bladder preserving approach and not immediate radical cystectomy (RC). In this study we have shown that a quarter of patients with T1 bladder cancer and residual T1 on re-TURBT who are treated with immediate RC are found to have carcinoma invading bladder muscle at RC and 5% have lymph node metastases. We have also found that >30% of patients treated with deferred RC after initial bladder-preserving therapy harbour carcinoma invading bladder muscle and almost 20% of these patients have lymph node metastases. Thus, immediate RC should be considered in all patients with T1 bladder cancer and residual T1 on re-TURBT. OBJECTIVE To report the overall survival (OS) and cancer-specific survival (CSS) of patients with residual T1 bladder cancer on restaging transurethral resection of the bladder tumour (re-TURBT). MATERIALS AND METHODS We performed a retrospective review of 150 evaluable patients treated for T1 bladder cancer with residual T1 disease found on re-TURBT between 1990 and 2007. Patients were treated with immediate radical cystectomy (RC) or a bladder-preserving approach (deferred or no RC). A univariate Cox proportional hazards regression model was used to test the association between treatment approach and survival. RESULTS Residual T1 bladder cancer was found in 150 evaluable patients, of whom 57 received immediate RC and 93 were treated with a bladder-preserving approach. Fourteen out of 57 patients receiving immediate RC and 8/26 patients receiving deferred RC had carcinoma invading bladder muscle in the RC specimen. Three out of 57 and 5/26 patients had lymph node metastases in the RC specimen. Median follow-up was 3.74 years. Thirty-nine patients died during follow-up, 16 from bladder cancer. There was no significant association between immediate RC and CSS (hazard ratio [HR] 1.15, 95% confidence interval [CI] 0.43-3.09, P = 0.8) or OS (HR 0.79, 95% CI 0.4-1.53, P = 0.5). CONCLUSIONS Because of the low number of events we cannot conclude whether RC offers a survival advantage in patients with residual T1 bladder cancer on re-TURBT. Since a quarter of patients had carcinoma invading bladder muscle, RC should be considered in these patients. A larger, preferably randomized, study with longer follow-up is needed.

Abstract
Background The purpose of this study was to establish the clinical performance of a urine-based assay, called a multianalyte diagnostic readout, in monitoring for bladder cancer recurrence. Methods This was a prospective, multicenter, single assessment observational study. The multianalyte diagnostic readout uses a combination of one protein and three DNA biomarkers. Urine samples from 733 patients undergoing monitoring for bladder cancer recurrence were analyzed for matrix metalloproteinase-2 levels, the presence of mutant FGFR3 DNA, and hypermethylation of the NID2 and VIM genes. The probability of a patient having (positive predictive value) or not having (negative predictive value) recurrent bladder cancer was determined by FGFR3 alone or all four biomarkers combined, respectively. Results Cystoscopy/biopsy diagnosed 63 patients with bladder cancer recurrence at the time of study assessment. The four-biomarker assay identified 237 patients as having a low probability of disease recurrence, 231 of whom were determined by cystoscopy as not having recurrent cancer, resulting in a negative predictive value of 97.5% at 90.5% sensitivity. The FGFR3 assay identified 49 patients with FGFR3 mutations, 19 of whom were confirmed by biopsy as having cancer, resulting in a positive predictive value of 38.8%, with 95.5% specificity. Conclusion The urine-based multianalyte diagnostic readout assay was able to delineate the patient population into those highly likely to have bladder cancer recurrence, those unlikely to have recurrent disease, and those with an average risk for bladder cancer recurrence.

Urol Ann 2011; 3:127-32. [PMID: 21976924 PMCID: PMC3183703 DOI: 10.4103/0974-7796.84960] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2010] [Accepted: 03/01/2011] [Indexed: 11/17/2022] Open
Abstract
Context: The optimal time of cystectomy for nonmuscle invasive bladder cancer (NMIBC) is controversial. Aim: This study aims at comparing cancer-specific survival in primary versus deferred cystectomy for T1 bladder cancer. Settings and Design: Between 1990 and 2004, a retrospective cohort of 204 patients was studied. Materials and Methods: Primary cystectomy at the diagnosis of NMIBC was performed in 134 patients (group 1) and deferred cystectomy was done after failed conservative treatment in 70 (group 2) Both groups were compared regarding patient and tumor characteristics and cancer-specific survival. Statistical Analysis Used: Cancer-specific survival was calculated using the Kaplan-Meier method. Results: Mean follow-up was 79 and 66 months, respectively, in the two groups. Tumor multiplicity was more frequent in group 2; otherwise, both groups were comparable in all characteristics. The definitive stage was T1 in all patients. Although the 3-year (84% in group 1 vs. 79% in group 2), 5-year (78% vs. 71%) and 10-year (69% vs. 64%) cancer-specific survival rates were lower in the deferred cystectomy group, the difference was not statistically significant. In group 2, survival was significantly lower in cases undergoing more than three transurethral resections of bladder tumors (TURBT) than in cases with fewer TURBTs. Conclusions: Cancer-specific survival is statistically comparable for primary and deferred cystectomy in T1 bladder cancer, although there is a non-significant difference in favor of primary cystectomy. In the deferred cystectomy group, the number of TURBTs beyond three is associated with lower survival. Conservative treatment should be adopted for most cases in this category.

Abstract
BACKGROUND The aim of this study was to prospectively compare single-dose intravenous antibiotic prophylaxis vs. no prophylaxis before minor cystoscopic procedures, including punch biopsy and transurethral resection (TUR) of small bladder tumors. MATERIALS AND METHODS A total of 200 patients with a mean age of 47.3 years old (range: 19-84 years old) with initial negative urine cultures were recruited. All patients underwent a diagnostic cystoscopy. Patients were then randomized into 2 groups: One group that did not receive antibiotics (100 patients) and the other group that received antibiotic treatment (100 patients with a single intravenous dose of cefoperazone). All patients had urine analysis and urine cultures on the second day after the operation. Additionally, clinical parameters including fever and dysuria were recorded. In 15% of the patients, incidental additional interventions such as punch biopsy or TUR of a small bladder tumor that were similarly distributed in both groups were performed. RESULTS In 1 patient from the antibiotic group and 2 patients from the no prophylaxis group, the urine cultures after cystoscopy were positive. No statistically significant difference was observed between these groups based on the microbiological and clinical parameters. CONCLUSION The current study provides evidence that no antibiotic prophylaxis is required before diagnostic cystoscopy in patients without bacteriuria. But, the absolute risk of infection was small, suggesting that a much larger study is required.

Abstract
Bladder cancer comprises a heterogeneous group of tumors, the majority of which are non-muscle-invasive bladder cancer (NMIBC) at initial presentation. Low-risk bladder cancer--defined as pTa low-grade papillary tumors--is the type of NMIBC with the most favorable oncologic outcome. Although the risk of progression is less than 1% in 5 years, almost 15% will recur after 1 year, and 32% after 5 years. A complete transurethral resection, followed by an immediate single postoperative instillation of chemotherapy will reduce the risk of recurrence for the first 2 years. Follow-up cystoscopy is required to detect recurrence; in the vast majority of cases the recurrent tumor is of the same stage and grade as the primary tumor. The first follow-up visit, 3 months after surgery, is the most important in predicting risk of recurrence for the future. Recent developments in profiling urine and cancer tissue make it possible to better predict risk of progression and recurrence. In the future this profiling will play an important role in the timing and the choice of treatment, as well as guiding follow-up procedures.

Abstract
OBJECTIVE The aim of this study was to prospectively assess the diagnostic capabilities of transabdominal sonography performed with newer sonography machines for showing focal bladder wall abnormalities (FBWAs) detected on cystoscopy. METHODS One hundred twelve consecutive patients (97 male and 15 female; mean age, 68 years) underwent cystoscopy. Reasons for referral were macroscopic hematuria (44 cases [39%]), surveillance after transurethral resection (56 cases [49.5%]), and incidental sonographic findings (12 cases [11.5%]). One to 2 days before cystoscopy, sonography was carried out by a single operator who was blinded to clinical and recent sonographic findings. The presence, size, number, and location of FBWAs (eg, polypoid vegetations and asymmetric bladder wall thickening) were recorded and compared with cystoscopic and histologic findings. RESULTS One hundred ten patients with a histologic diagnosis were available for the study. Benign conditions, nontransitional tumors, and transitional tumors were found in 26.3%, 3.7% and 70% of the patients, respectively. The sensitivity, specificity, positive predictive value, negative predictive value, and overall accuracy of sonography of cystoscopic lesions were 91.4%, 79.3%, 91.4%, 79.3%, and 88.2%. Cancers of 15 mm or smaller and flat tumors were often missed by sonography, whereas chronic cystitis accounted for most of the false-positive sonographic findings; however, sonography had poor capability of characterizing FBWAs, with specificity of 62%. In this respect, color Doppler findings proved of little aid as well. CONCLUSIONS In patients selected for cystoscopy, transabdominal sonography with newer sonography machines showed good diagnostic accuracy for focal alterations of the bladder wall found on cystoscopy.

Abstract
PURPOSE The study aims to evaluate the efficacy and toxicity of fenretinide in preventing tumor recurrence in patients with transitional cell carcinoma (TCC) of the bladder. EXPERIMENTAL DESIGN We conducted a multicenter phase III, randomized, placebo-controlled trial of fenretinide (200 mg/day orally for 12 months) in patients with non-muscle-invasive bladder TCC (stages Ta, Tis, or T1) after transurethral resection with or without adjuvant intravesical Bacillus Calmette-Guerin (BCG). Patients received cystoscopic evaluation and bladder cytology every 3 months during the 1-year on study drug and a final evaluation at 15 months. The primary endpoint was time to recurrence. RESULTS A total of 149 patients were enrolled; 137 were evaluable for recurrence. The risk of recurrence was considered to be "low" in 72% (no prior BCG) and intermediate or high in 32% (prior BCG) of the evaluable patients. Of the lower-risk group, 68% had solitary tumors and 32% had multifocal, low-grade papillary (Ta, grade 1 or grade 2) tumors. The 1-year recurrence rates by Kaplan-Meier estimate were 32.3% (placebo) versus 31.5% (fenretinide; P = 0.88 log-rank test). Fenretinide was well tolerated and had no unexpected toxic effects; only elevated serum triglyceride levels were significantly more frequent on fenretinide (versus placebo). The Data Safety and Monitoring Board recommended study closure at 149 patients (before reaching the accrual goal of 160 patients) because an interim review of the data showed a low likelihood of detecting a difference between the two arms, even if the original accrual goal was met. CONCLUSIONS Although well tolerated, fenretinide did not reduce the time-to-recurrence in patients with Ta, T1, or Tis TCC of the bladder.

Clinical significance of urine heparanase in bladder cancer progression. Neoplasia 2008; 10:125-30.

Abstract
Heparanase is an endo-beta-glucuronidase capable of cleaving heparan sulfate (HS), an activity implicated in tumor metastasis. Heparanase expression is upregulated in primary human tumors, correlating with reduced post operative survival and elevated microvessel density. An ELISA method was used to quantify heparanase in urine from 282 individuals. Urine was collected from healthy volunteers (n = 41), patients diagnosed with noncancerous pathologic disorders (n = 90), and bladder cancer patients (n = 92). Fifty-nine bladder carcinoma patients after transurethral resection (TUR) with no evidence of disease (NED) were also included. Heparanase levels were significantly elevated in urine from bladder cancer patients compared with healthy controls (P < .001) and with noncancerous urinary disorders (P < .05). Heparanase elevation strongly correlated with tumor grade (P < .001) and stage (P = .027). An optimal cutoff value of 154 pg/ml was determined. Of 199 individuals enrolled (59 patients after TUR and 24 patients with recurring disease were excluded), 65 had heparanase levels above 154 pg/ml. Only 3 of 65 (4.6%) were healthy individuals. In contrast, 52.3% (34 of 65) of individuals with heparanase levels above 154 pg/ml were bladder cancer patients. The results indicate that urine heparanase levels are elevated during bladder cancer progression, suggesting that the ELISA method may be applied for bladder cancer diagnosis.

Abstract
BACKGROUND Superficial (papillary) bladder cancer is associated with progression and death from muscle-invasive bladder cancer, but no reliable predictors of the outcomes have been identified. METHODS We analyzed the long-term prognostic effect of DNA flow cytometry in bladder washings from 93 subjects with previously resected T(a) and T(1) bladder tumors who participated in a chemoprevention trial of the synthetic retinoid fenretinide. Kaplan-Meier analysis and Cox regression were used to determine the prognostic effect of DNA aneuploidy on cancer progression and mortality in conjunction with conventional clinical factors after a median of 11.5 years (interquartile range, 9.5-11.7 years). RESULTS Overall, 58 of 93 (62%) specimens were DNA aneuploid at baseline. Progression-free survival was significantly shorter in subjects with stage T(1) [hazard ratio (HR), 31.6; 95% confidence interval (95% CI), 2.6-386.1; P < 0.001] and in subjects with baseline DNA aneuploid washing (HR, 10.5; 95% CI, 1.1-126.1; P = 0.03). The risk of death was also greater for stage T(1) tumors (HR, 2.6; 95% CI, 1.04-6.7; P = 0.04). DNA aneuploidy was a significant prognostic factor also for overall survival (HR, 2.8; 95% CI, 1.0-9.0; P = 0.05). Fenretinide treatment had no significant effect on cancer progression and death. CONCLUSIONS DNA aneuploidy in washings from endoscopically normal bladder is a significant predictor of progression and death in addition to tumor stage. This biomarker may help to identify and monitor a high-risk group who may benefit from a chemoprevention intervention.

Abstract
OBJECTIVE To evaluate the use of a multiprobe fluorescent in situ hybridization (FISH) assay for determining the response of patients with high-risk superficial bladder tumour (HRSBT) to bacillus Calmette-Guérin (BCG) therapy. METHODS Bladder washing specimens from 65 HRSBT patients collected before and after BCG therapy were analyzed by FISH. Labelled probes for chromosomes 3, 7, 9, and 17 were used to assess chromosomal abnormalities indicative of malignancy. RESULTS Fifty-five of 65 (85%) patients had a positive pre-BCG FISH result; 29 (45%) patients had a positive and 36 (55%) had a negative post-BCG FISH result. Patients with a positive post-BCG FISH status had a 2.7 times higher risk for tumour recurrence than patients with a negative post-BCG FISH status (p = 0.017; 95% CI: 1.18-6.15). In addition, patients who maintained a positive FISH status before and after BCG therapy had a risk for tumour recurrence 2.96 times higher than patients whose FISH result changed from positive to negative after BCG (p = 0.02; 95% CI: 1.17-7.54). On the other hand, there was no significant difference between the risk for tumour progression in patients with a positive versus a negative post-BCG FISH result (p = 0.49). CONCLUSIONS The high percentage of positive pre-BCG FISH results suggests the need for adjuvant therapy in patients with HRSBT after the initial transurethral resection. In addition, patients with a positive post-BCG FISH result were more likely to relapse after therapy. Thus, FISH appears to be useful for the surveillance of patients with HRSBT following BCG therapy.

Abstract
Bladder cancer is a common genitourinary malignancy that demonstrates a great variation in risk of tumor recurrence and progression following treatment. The dramatic differences in clinical behavior dictate vastly differing treatments, which may range from simple surveillance to combination radical surgery with systemic chemotherapy. For non-muscle invasive bladder cancer prediction of the risk of recurrence and progression is necessary to assess the need for intravesical therapy and possible early cystectomy. In contrast, prediction of advanced disease response to primary treatment such as cystectomy and the response to systemic chemotherapy plays an important role in treatment assignment for patients with muscle invasive disease. To estimate these risk traditional risk grouping schemes such as the present TNM staging system has been used to guide patient treatment. More recently, improved prognostic tools such as nomograms have been developed to provide a more accurate assessment of outcomes. Clinicians are enthusiastically working to utilize these statistical methods in bladder cancer. We summarize the current status of outcome predictive models for bladder cancer; and focus particularly on the ability of nomograms to predict disease recurrence, progression, and patient survival.
