Modified immunoscore improves the prediction of progression-free survival in patients with non-muscle-invasive bladder cancer: A digital pathology study. Front Oncol 2022; 12:964672. [PMID: 36212478 PMCID: PMC9539272 DOI: 10.3389/fonc.2022.964672] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Accepted: 09/05/2022] [Indexed: 12/24/2022] Open
Abstract
Tumour-infiltrating lymphocytes (TIL), known to be of prognostic value in various solid tumours, have been in the focus of research in the last years. TIL are often quantified via IMMUNOSCORE ® (IS), a scoring system based on TIL cell densities. Recent studies were able to replicate these findings for muscle-invasive bladder cancer (MIBC), however data regarding non-muscle-invasive bladder cancer (NMIBC) are scarce. This study aimed to evaluate the value of a modified Immunoscore (mIS) as a predictive marker for NMIBC prognosis using tissue-micro-arrays (TMAs). We analysed two TMAs containing 316 samples from 158 patients with NMIBC, stained for CD3, CD8, CD45RO and FOXP3. Stained TIL were captured by digital pathology, cumulated, averaged, and reported as density (stained cells per mm²). The mIS was then constructed based on density of all four immune-cell types. Clinical, pathological and follow-up data were collected retrospectively. Univariable and multivariable cox regression analysis was performed to assess the potential value of mIS as a predictor for progression free survival (PFS) and recurrence-free-survival (RFS). Patients within "European Organisation for Research and Treatment of Cancer" (EORTC) risk groups were further substratified in high mIS and low mIS subgroups. Finally log-rank test was used to compare the different survival curves. The median age in our cohort was 68 years (Interquartile Range (IQR): 60 - 76), and 117 (74%) patients were male. A total of 26 patients (16.5%) were classified as EORTC low risk, 45 (28.5%) as intermediate risk and 87 (55.1%) as high risk. Patients in the EORTC high risk group with low mIS showed a shorter PFS in comparison to high mIS (HR 2.9, CI 0.79 - 11.0, p=0.082). In contrast, no predictive potential regarding PFS was observed in intermediate or low risk groups. Furthermore, mIS was not able to predict RFS in any EORTC risk group. mIS could be utilized to predict prognosis more accurately in high-risk patients with NMIBC by identifying those with higher or lower risk of progression. Therefore, mIS could be used to allocate these highrisk patients to more streamlined follow-up or more aggressive treatment strategies.

Abstract
Background Bladder cancer is the most common malignant tumor of the urinary system. One of the biological characteristics of NMIBC is the high recurrence rate after surgery. The implementation of this project aimed to investigate the role of pharmacogenomic testing-guided intravesical perfusion of chemotherapeutic agents in the postoperative perfusion therapy for non-muscle invasive bladder cancer. Method From January 2015 to December 2016, 298 patients with non-muscle-invasive bladder cancer were enrolled in this prospective study. These patients received chemotherapy drugs after electrotherapy. According to the presence or absence of tumor susceptibility gene detection after surgery, they were divided into two groups, including the drug sensitive group(N = 44) and the control group(N = 254). The drug sensitive group received bladder infusion therapy with sensitive chemotherapy drugs based on drug sensitivity gene detection results. The control group received intravesical instillation of pirarubicin. The preoperative general data and tumor grade of patients were recorded. Cystoscopy was performed before and every 3 months after surgery. The chest CT, upper abdomen CT, renal function, and urinary routine tests were performed. Tumor recurrence, metastasis and tumor-related death were recorded and evaluated during follow-up. Results The drug sensitive group, which selected high-sensitivity drugs for intravesical instillation therapy based on gene expression, has a significantly lower relapse rate (11.36% vs 37.40%, P < 0.05) and a significantly longer time to relapse (17.80 ± 7.20 month vs11.20 ± 6.10 month, P < 0.05) compared with the control group. There were no significant differences in the time of mortality and death time between two groups. Conclusion The pharmacogenomic testing-directed bladder instillation of chemotherapeutic drugs may be more effective than empiric drug administration in reducing the recurrence rate of non-muscle-invasive bladder cancer.

Assessing the Impact of the Absence of Detrusor Muscle in Ta Low-grade Urothelial Carcinoma of the Bladder on Recurrence-free Survival. Eur Urol Focus 2020; 7:1324-1331. [PMID: 32900676 DOI: 10.1016/j.euf.2020.08.007] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2020] [Revised: 07/27/2020] [Accepted: 08/25/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND Obtaining detrusor muscle (DM) in transurethral resection of bladder tumor (TURBt) specimen is considered a surrogate marker of resection quality. However, evidence was principally investigated in high-risk tumors. Therefore, DM sampling for low-grade (LG) urothelial carcinoma (UC) remains poorly investigated and certainly requires further investigation. OBJECTIVE To assess whether the absence of DM in TURBt specimen has a negative impact on recurrence-free survival (RFS) in patients with a Ta LG UC. DESIGN, SETTING, AND PARTICIPANTS A multicenter TURBt database was queried for "LG, Ta, UC of the bladder." All patients treated between 1996 and 2018 with tumor grade assessed according to both 1973 World Health Organization and 2004 WHO/International Society of Urological Pathology grading classifications and with a minimum follow-up of 1 yr were included. Patients with a previous history of high-grade UC, upper urinary tract UC, or bladder tumor differentiations other than UC were excluded. INTERVENTION TURBt. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Baseline demographic, clinical, and pathologic data were analyzed. The European Organization for Research and Treatment of Cancer (EORTC) risk group was recorded. Kaplan-Meier analysis was performed to assess the predictive role of clinical and pathologic data for RFS. Univariable and multivariable Cox regression analyses were performed to identify the predictors of recurrence. RESULTS AND LIMITATIONS Overall, 521 patients were included. At Kaplan-Meier analysis, the low-risk cohort displayed significantly higher RFS than the intermediate-risk cohort (1-yr RFS 87% vs 79%; log-rank p = 0.007). At univariable Cox regression analysis, only gender, multiple tumors, tumor diameter ≥3 cm, and EORTC risk group were significant predictors of recurrence. Absence of DM had no impact on RFS. Multivariable Cox regression analysis confirmed gender and EORTC risk group as independent predictors of recurrence. CONCLUSIONS Absence of DM in TURBt specimen has negligible role in RFS of patients with Ta LG tumors of the bladder. PATIENT SUMMARY In this study, we assessed the role that detrusor muscle (DM) in transurethral resection of bladder tumor specimen has in recurrence-free survival, in patients with a Ta low-grade urothelial carcinoma of the bladder. Absence of DM has no impact on tumor recurrence; therefore, it does not require additional attention.

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
We present a rare case of urothelial carcinoma in situ (CIS), which invades the prostate and seminal vesicle (SV). A 70-year-old man underwent transurethral resection of bladder (TURB), and the pathologic examination revealed multiple CIS. Although the patient received intravesical bacillus Calmette-Guerin (BCG) therapy following TURB, recurrence of CIS was confirmed in the bladder and left distal ureter at 3 months following BCG. Radical cystectomy was performed due to BCG-refractory CIS. Microscopically, CIS was found throughout the mucosa of the bladder, left ureter, prostatic duct, and both SVs. Next-generation sequencing revealed significant differences in tumor clonality between bladder and SV CIS cells. Among 101 (bladder CIS) and 95 (SV CIS) somatic mutations, only two were shared, and only one gene (ARHGAP23) was common exon coding region gene. In conclusion, multicentric genetic changes, in line with the field-cancerization effect, may result in SV involvement by CIS of the bladder.

Novel nomograms to predict recurrence and progression in primary non-muscle-invasive bladder cancer: validation of predictive efficacy in comparison with European Organization of Research and Treatment of Cancer scoring system. World J Urol 2018; 37:1867-1877. [PMID: 30535715 DOI: 10.1007/s00345-018-2581-3] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2018] [Accepted: 11/26/2018] [Indexed: 10/27/2022] Open
Abstract
PURPOSE To develop and validate novel nomograms to predict recurrence and progression after transurethral resection of bladder tumor (TURBT) in Korean patients with non-muscle-invasive bladder cancer (NMIBC). METHODS We retrospectively analyzed the clinical data on 970 newly diagnosed NMIBC patients after TURBT between 2000 and 2013 in a single institution. We used multivariate Cox proportional hazard models to identify the significant predictors of recurrence and progression, which resulted in the construction of the nomograms predicting the 5-year probability of recurrence and progression. We internally validated the nomograms using the area under the receiver-operating characteristics' curves and calibration plots. In addition, the clinical usefulness of each nomogram was assessed and compared with that of the European Organization of Research and Treatment of Cancer (EORTC)-scoring system using decision curve analysis (DCA). RESULTS The significant factors related to recurrence were gross hematuria at diagnosis, previous or concomitant upper urinary tract urothelial carcinoma (UTUC), pT1 tumor, high tumor grade, multiple tumors, and intravesical therapy. The significant predictors of progression were previous or concomitant UTUC, pT1 tumor, high tumor grade, carcinoma in situ, and lymphovascular invasion. The 5-year predictive accuracy of each nomogram was 65% for recurrence and 70% for progression, respectively. Compared with the EORTC-scoring system, the nomograms were generally well calibrated. On DCA, each nomogram presented better net benefit gains than did the EORTC-scoring system across a wide range of threshold probabilities. CONCLUSIONS Our novel nomograms are not completely accurate, but they show a reasonable level of discriminative ability, adequate calibration, and meaningful net benefit gain for the prediction of recurrence and progression after TURBT in Korean NMIBC patients. Additional external validation will be required to generalize the nomograms which we developed.

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
Bladder cancer is a heterogeneous disease that demonstrates a wide spectrum of histologic features. The modern classification of bladder cancer is largely based on pathologic analysis, which assesses tumor grade, stage, type, size, and other features that are essential for understanding the biological behavior of bladder cancer. Bladder cancers with similar histologic features are likely to show comparable responses to a new therapeutic agent in clinical trial. Furthermore, pathologic analysis also evaluates the quality of tissue samples in clinical trial to ensure the integrity of various molecular tests. In spite of the emerging role of genomic and molecular studies, pathology remains the cornerstone in the diagnosis, prognosis, and treatment of bladder cancer. Herein, the pathologic considerations for bladder cancer clinical trial planning are reviewed.

Low-Grade, Multiple, Ta Non-muscle-Invasive Bladder Tumors: Tumor Recurrence and Worsening Progression. Indian J Surg Oncol 2018; 9:157-161.

Abstract
Nearly half of newly diagnosed cases of bladder cancer are low grade, noninvasive, and papillary tumors. The standard treatment for non-muscle-invasive bladder cancer (NMIBC) has been transurethral resection of the bladder tumor (TUR-BT) with or without adjuvant intravesical instillation (IVI) of chemotherapy or Bacillus Calmette-Guerin (BCG) therapy. NMIBC is known to be associated with high rates of recurrence and risk of progression. In this study, we have retrospectively analyzed the clinical outcome of initially diagnosed multiple low-grade Ta tumors, with a special focus on tumor recurrence and worsening progression (WP) pattern. We retrospectively reviewed 42 patients with primary, multiple, low-grade Ta bladder cancer. We defined WP as confirmed high-grade Ta, all T1 or Tis/concomitant CIS of bladder recurrence, upper urinary tract recurrence (UTR), or progression to equal to or more than T2. The associations between clinico-pathological factors and tumor recurrence as well as WP pattern were analyzed. Tumor recurrence and WP occurred in 23 (54.76%) and 8 (19.04%) patients during follow-up (median follow-up: 57.38 months), respectively. WP to high grade/stage was seen in 8 patients. Multivariate analysis demonstrated that use of tobacco (p < 0.0001) and absence of IVI (p < 0.0001) were significant risk factors for tumor recurrence. The 5-year recurrence-free survival rate for non-tobacco users (74.0%) was significantly higher than that for tobacco users (42.5%, p = 0.0001), and also higher for patients receiving intravesical instillation (84.2 vs. 30.0% without IVI, p = 0.0001). Recurrence is common in patients with low-grade, Ta bladder cancer, especially in the setting of multiplicity. Recurrences occurred in 54.76% of patients and WP occurred in 19.04% of patients. Use of tobacco and non-use of IVI were strongly associated with high recurrence rate.

Abstract
WW domain-containing oxidoreductase (WWOX) gene located in the common fragile site FRA16D region exhibits loss or reduction of expression in multiple types of carcinomas including bladder cancer. However, the role of WWOX in the tumorigenesis and development of bladder cancer remains elusive. In this study, WWOX overexpression construct was transfected into 5637 bladder cancer cell line in which WWOX expression was compromised. Constitutive expression of ectopic WWOX in 5637 cells suppressed cell proliferation and cell cycle progression, which was associated with downregulation of Cyclin B, D1, and E. Moreover, WWOX overexpression promoted apoptosis in 5637 cells and resulted in upregulation of Bax, downregulation of Bcl-2, and elevated levels of cleaved caspase-3 and cleaved PARP, indicating activation of the intrinsic apoptosis pathway. Furthermore, WWOX overexpression suppressed tumorigenicity of 5637 cells and promoted apoptosis in the xenograft tumors as demonstrated in a xenograft mouse model. In summary, our data indicate that WWOX plays a critical role in the regulation of proliferation, cell cycle, apoptosis, and tumorigenesis of bladder cancer cells, suggesting that WWOX may have potential clinical implications in bladder cancer therapy.

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.

Abstract
Justicidin A (JA) is one of the methanol extracts of Justicia procumbens and was reported to induce apoptosis and inhibit the proliferation of human colon cancer cells. Using bladder cancer as a paradigm, this study was designed to identify the novel molecular basis underlying the antiangiogenic activities of JA and its potential in cancer therapy. Human bladder cancer cell lines (TSGH8301 and RT4) and immortalized uroepithelial cell lines (E6 and E7) were chosen to investigate the efficacy of JA in cell proliferation, apoptosis, and angiogenesis in vitro. The biological effects of JA treatment in vivo were examined using a xenograft tumor model in SCID mice. JA showed a dose-dependent and time-dependent inhibition of cell proliferation on TSGH8301 cancer cells, with IC50 values determined to be 0.44 μmol/l. Of interest, TSGH8301 cancer cells were more sensitive to JA than E7 immortalized uroepithelial cells, especially at lower concentrations. We further showed that JA inhibited the autocrine production of angiogenic factors and matrix-degrading enzymes in vitro and microvessel density in SCID mice in vivo (P< 0.01). Both differential cytotoxicity and angiogenesis inhibition of JA were confirmed by SCID mice experiments. Together, JA showed antiangiogenesis in vitro and in vivo through pleiotropic positive and negative regulators of angiogenesis molecules. The current investigation supports the potential of JA as an alternative chemoprevention agent for human bladder cancer.

Abstract
While clinical trials have led to many advances in the treatment of bladder cancer, important gaps in knowledge persist. Population-based studies have made important contributions to what is known about bladder cancer and can contribute unique insights to practice and policy. In addition to evaluating effectiveness of interventions in routine practice, population-based studies can identify gaps between evidence and practice, and generate knowledge that cannot be gained from clinical trials. In this review we will highlight how population-based research has informed practice, policy, and the research agenda for bladder cancer.

Abstract
OBJECTIVE The aim of this study was to evaluate tumour growth located around the ureteric orifice (LUO) at primary diagnosis of Ta/T1 urinary bladder cancer in relation to effects on recurrence and progression. MATERIALS AND METHODS Clinical and pathological characteristics of patients diagnosed with primary Ta/T1 urinary bladder cancer from 1992 to 2007 were recorded prospectively. Location of the primary tumour and growth around the ureteric orifice (within 1 cm) were recorded and correlated with recurrence and progression during further follow-up. Hazard ratios (HRs) were estimated using Cox regression with 95% confidence intervals (CIs) in both univariate and multivariate analysis. RESULTS The study included 768 evaluable patients with a median follow-up of 60 months. Recurrence was observed in 478 patients (62%) and progression in 71 (9%). Growth of a primary tumour adjacent to the ureteric orifice was associated with recurrence (HR = 1.28, 95% CI = 1.07-1.54) but not progression (HR = 1.04, 95% CI = 0.65-1.67). The most common location of the first recurrence was the posterior bladder wall (29%). Other locations in the bladder did not predict recurrence or progression. Additional factors affecting recurrence were tumour size greater than 15 mm, T1 tumour category, multiplicity, malignant or missing/not representative bladder wash cytology and surgery performed by residents. CONCLUSIONS A primary tumour located around the ureteric orifice was predictive of recurrence, which could be taken into account in future follow-up schedules.

Prediction model for recurrence probabilities after intravesical chemotherapy in patients with intermediate-risk non-muscle-invasive bladder cancer, including external validation. World J Urol 2015; 34:173-80.

Abstract
PURPOSE To develop a model to predict recurrence for patients with intermediate-risk (IR) non-muscle-invasive bladder cancer (NMIBC) treated with intravesical chemotherapy which can be challenging because of the heterogeneous characteristics of these patients. METHODS Data from three Dutch trials were combined. Patients treated with intravesical chemotherapy with characteristics according to the IR definition of the EAU guideline 2013 were included. Uni- and multivariable Cox regression with selection methods were used to identify predictors of recurrence at 1, 2, and 5 years. An easy-readable table for recurrence probabilities was developed. An external validation was done using data from Spanish patients. RESULTS A total of 724 patients were available for analyses, of which 305 were primary patients. Recurrences occurred in 413 patients (57%). History of recurrences, history of intravesical treatment, grade 2, multiple tumors, and adjuvant treatment with epirubicin were relevant predictors for recurrence-free survival with hazard ratios of 1.48, 1.38, 1.22, 1.56, and 1.27, respectively. A table for recurrence probabilities was developed using these five predictors. Based on the probability of recurrence, three risk groups were identified. Patients in each of the separate risk groups should be scheduled for less or more aggressive treatment. The model showed sufficient discrimination and good predictive accuracy. External validation showed good validity. CONCLUSION In our model, we identified five relevant predictors for recurrence-free survival in IR-NMIBC patients treated with intravesical chemotherapy. These recurrence predictors allow the urologists to stratify patients in risk groups for recurrence that could help in deciding for an individualized treatment approach.

Abstract
Objectives The aim of this study was to evaluate the effect of bladder tumor (BT) location on prostate cancer (PCa) detection in patients with elevated PSA levels after intravesical BCG instillation. Methods Between February 2004 and January 2013 prostate biopsies were performed in 59 non-muscle invasive bladder cancer (NMIBC) patients whose PSA level were elevated (≥3 ng/ml) after a 6 week course of intravesical BCG (Oncotice, 12.5 mg in 50 ml normal saline). Differences in PCa detection according to the BT location [bladder neck and/or trigone (Group 1, n = 22) vs. other locations (Group 2, n = 37)] were evaluated. The Fisher's exact test and the Mann-Whitney U test were used to evaluate the association between categorical and continuous variables, respectively. Results A total of 14 patients (23.7%) were diagnosed with PCa. The mean ± standard deviation (SD) PSA before intravesical BCG instillation and prostate biopsy were 1.36±1.04 ng/ml in Group 1 and 1.09±1.12 ng/ml in Group 2 (P = 0.633), and 6.05±3.57 ng/ml in Group 1 and 5.13±3.88 ng/ml in Group 2 (P = 0.378), respectively. Interestingly, whereas PCa was detected upon biopsy in only one patient in Group 1 (4.5%), 13 cases were detected in Group 2 (35.1%) (P = 0.009). Conclusions PCa detection after intravesical BCG was highly associated with BT location. Prostate biopsy should therefore be considered when PSA level is elevated after BCG instillation and his BT is located far from the bladder neck.

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
Non-muscle invasive bladder cancer (NMIBC) accounts for approximately 70 % of all bladder cancer cases and represents a heterogeneous pathological entity, characterized by a variable natural history and oncological outcome. The combination of cystoscopy and urine cytology is considered the gold standard in the initial diagnosis of bladder cancer, despite the limited sensitivity. The first step in NMIBC management is transurethral resection of the bladder tumour (TURBT). This procedure is marked by a significant risk of leaving residual disease. The primary landmark in NMIBC is the high recurrence rate. Fluorescence cystoscopy improves the bladder cancer detection rate, especially for flat lesions, and improves the recurrence-free survival by decreasing residual tumour. Progression to muscle invasive tumours constitutes the second important landmark in NMIBC evolution. Stage, grade, associated CIS and female gender are the major prognostic factors in this regard. The evolution to MIBC has a major negative impact upon the survival rate and quality of life of these patients. Fluorescence cystoscopy improves the detection rate of bladder cancer but does not improve the progression-free survival. Urine markers such as ImmunoCyt and Uro Vysion (FISH) have also limited additional value in diagnosis and prognosis of NMIBC patients. Major drawbacks are the requirement of a specialized laboratory and the additional costs. In this review, the risks of recurrence and progression are analysed and discussed. The impact of white light cystoscopy, fluorescence cystoscopy and urine markers is reviewed. Finally, the means and recommendations regarding follow-up are discussed.

Abstract
PURPOSE DNA methylation is associated with bladder cancer and these modifications could serve as useful biomarkers. FGFR3 mutations are present in 60% to 70% of non-muscle invasive bladder cancer (NMIBC). Low-grade bladder cancer recurs in more than 50% of patients. The aim of this study is to determine the sensitivity and specificity of a urine assay for the diagnosis of recurrences in patients with a previous primary NMIBC G1/G2 by using cystoscopy as the reference standard. EXPERIMENTAL DESIGN We selected eight CpG islands (CGI) methylated in bladder cancer from our earlier genome-wide study. Sensitivity of the CGIs for recurrences detection was investigated on a test set of 101 preTUR urines. Specificity was determined on 70 urines from healthy males aged more than 50 years. A 3-plex assay for the best combination was developed and validated on an independent set of 95 preTUR, recurrence free, and nonmalignant urines (n=130). RESULTS The 3-plex assay identified recurrent bladder cancer in voided urine with a sensitivity of 74% in the validation set. In combination with the FGFR3 mutation assay, a sensitivity of 79% was reached (specificity of 77%). Sensitivity of FGFR3 and cytology was 52% and 57%, respectively. CONCLUSION The combination of methylation and FGFR3 assays efficiently detects recurrent bladder cancer without the need for stratification of patients regarding methylation/mutation status of the primary tumor. We conclude that the sensitivity of this combination is in the same range as cystoscopy and paves the way for a subsequent study that investigates a modified surveillance protocol consisting of the urine test followed by cystoscopy only when the urine test is positive.

Abstract
Background and Objective. The cell cycle is regulated by proteins at different checkpoints, and dysregulation of this cycle plays a role in carcinogenesis. Matrix metalloproteinases (MMPs) are enzymes that degrade collagen and promote tumour infiltration. The aim of this study was to evaluate the expression of various cell cycle regulators and MMPs and to correlate such expression with progression and recurrence in patients with stage T1 urothelial carcinoma of the bladder (UCB). Patients and Methods. This population-based cohort study comprised 201 well-characterized patients with primary stage T1 urothelial carcinoma of the bladder. Immunohistochemistry was performed on formalin-fixed material to quantify expression of cell cycle regulators and two MMPs. Results. Normal expression of p53 and abnormal expression of MMP9 were associated with greater risk of tumour recurrence. Also, normal p16 expression was related to a lower risk of tumour progression. MMP2, p21, cyclin D1, and pRb showed no significant results that could estimate progression or recurrence. Conclusions. Normal p16 expression is associated with a lower risk of tumour progression, but immunohistochemistry on cell cycle regulators and MMPs has little value in predicting the prognosis in stage T1 UCB.

Abstract
BACKGROUND The prognostic value of CK20, Ki-67, and p53 has been investigated for non-muscle-invasive urothelial bladder cancers but not for the distinct and clinically challenging subset of pT1 bladder cancers. OBJECTIVE To evaluate the prognostic value of CK20, Ki-67, and p53 within the largest series of pT1 urothelial bladder cancers. DESIGN, SETTING, AND PARTICIPANTS Data from 309 patients with pT1 urothelial bladder cancer from one single urologic centre were collected. INTERVENTION Adjuvant instillation of bacillus Calmette-Guérin was performed in each patient. A second resection was performed after 4-8 wk. A total of 76 patients underwent cystectomy. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS We conducted histomorphologic analysis; immunohistochemistry for CK20, Ki-67, and p53; and univariate and multivariate Cox regression models including recurrence-free survival (RFS), progression-free survival (PFS), and cancer-specific survival (CSS). RESULTS AND LIMITATIONS At a median follow-up of 49 mo, we found recurrence and progression and disease-specific mortality rates of 22.7%, 20.1%, and 15.9%, respectively. CK20 expression was significantly correlated with RFS in multivariate analysis (hazard ratio [HR]: 5.89; 95% confidence interval [CI], 1.44-24.15; p=0.014). In multivariate analysis, Ki-67 was the only marker significantly correlated with PFS (HR: 2.80; 95% CI, 1.45-5.43, p=0.002). Ki-67 (HR: 3.83; 95% CI, 1.59-9.26; p=0.003), and CK20 (HR: 8.44; 95% CI,1.16-61.34; p=0.035) were significantly correlated with CSS in multivariate analysis. The combination of CK20 and Ki-67 showed significantly worse RFS (p=0.026), PFS (p=0.003), and CSS (p<0.001) in tumours with a high proliferation index and abnormal CK20 expression. A retrospective study design was the major limitation of this study. CONCLUSIONS Our present analysis of the largest series of patients with pT1 urothelial bladder cancer published to date found Ki-67 and CK20 to be potential prognostic markers improving the risk stratification of pT1 bladder tumours. They are reliable indicators of biologic aggressiveness and may contribute to decision making on therapeutic strategy for pT1 bladder carcinomas.

Abstract
All or almost all neoplasias subjected to systematic cytogenetic scrutiny have been found to harbor acquired chromosomal aberrations. The paradigm stemming from the study of hematopoietic malignancies and sarcomas is that cancers are of monoclonal origin (i.e., they have developed from a single transformed somatic progenitor) because all the neoplastic parenchyma cells share at least one primary chromosomal abnormality, with subsequent clonal evolution along the lines of Darwinian selection occurring among the various subclones carrying secondary aberrations. When carcinomas began to be studied more extensively by cytogenetic methods, however, sometimes many cytogenetically unrelated clones were found, in seeming contradiction to the monoclonal hypothesis. Also studies of multiple samples from the same patient led to a rethinking of what the cytogenetic evidence really revealed about tumor clonality, both in its early stages and during disease development. The observed cytogenetic heterogeneity in, for example, tumors of the breast and pancreas vastly surpasses that of leukemias, lymphomas, connective tissue tumors, or even most epithelial, including uroepithelial, tumors. Theoretical reasoning as well as the available experimental data we here review show that the clonal evolution of neoplastic cell populations follows either of four principal pathways: (1) initial monoclonality is retained throughout the entire course of the disease with no additional, secondary aberrations accrued as judged by karyotypic appearance; (2) tumorigenesis is monoclonal but additional aberrations develop with time leading to secondary clonal heterogeneity (clonal divergence); (3) polyclonal tumorigenesis exists from the beginning but is followed by an overall reduction in genomic complexity with time (clonal convergence) due to selection among cytogenetically unrelated clones during tumor progression, resulting in secondary oligo- or monoclonality; or (4) polyclonal tumorigenesis with early clonal convergence is followed by later clonal divergence due to the acquisition of additional cytogenetic changes by the clone(s) that survived during the middle phases of tumor progression. Further studies of individual tumor cells are necessary to elicit precise information about the cell-to-cell variability that exists in many, especially epithelial, neoplasms and which holds the key to a more profound understanding of the complex issue of tumor clonality during all stages of cancer development.

Abstract
Purpose To evaluate the direct anti-cancer effect of a single instillation of epirubicin (SIE) after transurethral resection of bladder tumor (TURBT) for non-muscle-invasive bladder cancer (NMIBC) by analysis of immediate urine cytology (IUC). Materials and Methods We reviewed the records of 158 patients who had IUC after TURBT for NMIBC. Fifty-six patients were treated with SIE after TURBT and 102 patients were not treated with SIE. The direct anti-cancer effect of SIE was compared in the two groups according to the result of IUC. The relationship between SIE and IUC in NMIBC was analyzed by use of multivariate Cox proportional hazards regression models. Results The IUC-positive rate was 33.9% in the SIE group and 42.1% in the non-SIE group (p=0.005). The IUC-positive rate was lower in the SIE group than in the non-SIE group for each factor, including tumor stage, tumor grade, tumor size, tumor multiplicity, and preoperative urine cytology. Multivariate Cox proportional hazards regression analysis revealed that SIE was significantly associated with a negative IUC result in patients with NMIBC (HR, 0.163) (p<0.001). Conclusions These results indicate the direct anti-cancer effect of SIE in patients who undergo TURBT for NMIBC.

Abstract
The identification of patients with high-risk bladder cancer is important for the timely and appropriate treatment of this lethal disease. The understanding of the natural history of bladder cancer has improved; however, the criteria used to define high-risk disease and the relevant treatment strategies have remained the same for the past several decades, despite multiple large, randomized, prospective clinical trials that have evaluated the use of intravesical, surgical and systemic therapies. The genetic signature of high-risk bladder cancer has been a focus of investigation and has led to the discovery of potential molecular targets for disease identification, risk stratification and therapy. These advances, combined with a comprehensive risk assessment profile that incorporates available pathological and clinical characteristics, might improve the diagnosis and treatment of patients with bladder cancer.

Abstract
Transitional cell (urothelial) carcinoma of the bladder is the second most common urologic malignancy and is one of the best understood neoplasms, with relatively well-defined pathogenetic pathways, natural history, and tumor biology. Conventional clinical and pathologic parameters are widely used to grade and stage tumors and to predict clinical outcome of transitional cell carcinoma; but the predictive ability of these parameters is limited, and there is a lack of indices that could allow prospective assessment of risk for individual patients. In the last decade, a wide range of candidate biomarkers representing key pathways in carcinogenesis have been reported to be clinically relevant and potentially useful as diagnostic and prognostic molecular markers, and as potential therapeutic targets. The use of molecular markers has facilitated the development of novel and more accurate diagnostic, prognostic, and therapeutic strategies. FGFR3 and TP53 mutations have been recognized as key genetic pathways in the carcinogenesis of transitional cell carcinoma. FGFR3 appears to be the most frequently mutated oncogene in transitional cell carcinoma; its mutation is strongly associated with low tumor grade, early stage, and low recurrence rate, which confer a better overall prognosis. In contrast, TP53 mutations are associated with higher tumor grade, more advanced stage, and more frequent tumor recurrences. These molecular markers offer the potential to characterize individual urothelial neoplasms more completely than is possible by histologic evaluation alone. Areas in which molecular markers may prove valuable include prediction of tumor recurrence, molecular staging of transitional cell carcinoma, detection of lymph node metastasis and circulating cancer cells, identification of therapeutic targets, and prediction of response to therapy. With accumulating molecular knowledge of transitional cell carcinoma, we are closer to the goal of bridging the gap between molecular findings and clinical outcomes. Assessment of key genetic pathways and expression profiles could ultimately establish a set of molecular markers to predict the biological nature of tumors and to establish new standards for molecular tumor grading, classification, and prognostication. The main focus of this review is to discuss clinically relevant biomarkers that might be useful in the management of transitional cell carcinoma and to provide approaches in the analysis of molecular pathways that influence the clinical course of bladder cancer.

Abstract
Background There seems to be no consensus concerning taking bladder biopsies during transurethral resection of bladder tumor (TUR-BT). We investigate the clinical significance of bladder biopsy with TUR-BT and the relationship between urinary cytology and the biopsy results. Methods We reviewed a total of 424 patients with non-muscle invasive bladder cancer treated with TUR-BT between 1998 and 2005. Of the total, 293 patients also underwent a bladder biopsy. Biopsies from suspicious-appearing urothelium (N = 59) and those from normal-appearing urothelium (N = 234) were evaluated separately. Results Bladder cancer was observed in 23 cases (39.0%) who underwent a biopsy of suspicious-appearing urothelium. Among these 23 cases, 9 cases with visible tumor resection had carcinoma in situ (CIS) only in the biopsies from suspicious-appearing urothelium. Urinary cytology was negative in 3 of the 9 cases. Bladder cancer was observed in 26 cases (11.1%) who underwent a biopsy of normal-appearing urothelium. Of them, 5 cases with visible tumors had CIS only in the multiple biopsies from normal-appearing urothelium. Urinary cytology was positive in all of the 5 cases. No upstaging or upgrading cases were found in these patients by the addition of these two types of biopsy. Furthermore, therapy was not altered in these patients. With or without bladder biopsy was not a significant factor for tumor recurrence in either the univariate or multivariate analysis. Conclusions Based on the results, it is concluded the multiple biopsies from normal-appearing urothelium are not necessary in patients with negative cytology results because of the low detection rate and lack of influence on therapeutic decisions. Meanwhile, biopsy of suspicious-appearing urothelium is needed in patients with negative cytology results in order to detect CIS due to staging properties. This result supports a recent EAU guideline.

Abstract
Recent studies have shown that chromosome 9p21 locus is frequently deleted in the early stages of urothelial carcinogenesis. To study the predictive value of the 9p21 aberrations in recurrence of urothelial carcinoma of the urinary bladder, we applied dual-color fluorescence in situ hybridization for 9p21 and chromosome 9 centromere to the bladder washing cytology samples that were obtained from the patients with urothelial carcinoma of the urinary bladder treated by transurethral resection. For the evaluation, the 9p21 index was defined as the ratio of the mean number of 9p21 signals per nucleus for that of the chromosome 9 centromere signals per nucleus in each of the bladder washing cytology samples. The 9p21 index values of the bladder washing cytology samples with no (G0) cytologic atypia were significantly higher than those of the bladder washing cytology samples with moderate (G2) (P < .01) and severe (G3) (P < .001) cytologic atypia, but the index values did not statistically differ from those of the bladder washing cytology samples with mild (G1) cytologic atypia. Recurrence-free survival in the patients with a low 9p21 index value (<0.9) was significantly poorer in comparison with the patients with a high 9p21 index value (>0.9). Furthermore, 2 patients of bladder washing cytology G1 with a low 9p21 index value recurred much sooner than the other patients of the bladder washing cytology G1 category. These findings indicate that a decreased 9p21 index value is associated with recurrence of urothelial carcinoma of the urinary bladder, and the 9p21 index may be useful as a marker to identify patients with elevated risk of recurrence of urothelial carcinoma of the urinary bladder.

Abstract
OBJECTIVE To study, in addition to traditional tumor characteristics at diagnosis, the significance of DNA ploidy and S-phase fraction for tumor progression and tumor-related death in superficial carcinoma of the urinary bladder. MATERIAL AND METHODS Newly detected superficial bladder carcinomas (stage Ta-T1), from 195 consecutive patients were characterized according to stage, grade, tumor size, multiplicity, growth pattern, cytologic evaluation and random mucosal biopsies, as well as DNA ploidy and S-phase fraction as determined by means of DNA flow cytometry. The outcome of disease was evaluated using hospital charts and death certificates. RESULTS During a median follow-up period of 98 months (range 1-160 months), 28 patients (14%) progressed to muscle-invasive or metastatic disease and 24 (12%) died from disease. In univariate analysis all factors studied, with the exception of the size and number of tumors at diagnosis, were significantly related to progress and tumor-specific survival. In multivariate analysis, however, S-phase fraction was the most significant prognostic factor. When 21 high-risk patients with T1G3 tumors who underwent early cystectomy were excluded, S-phase fraction remained the most important prognostic factor. DNA ploidy failed as an independent predictor of survival. CONCLUSIONS High S-phase fraction at diagnosis of superficial urothelial carcinoma of the bladder identifies patients at high risk of progression and death from disease.

Abstract
Purpose Intravesical instillation of Gemcitabine may represent a useful second-line chemotherapy in case of non-muscle-invasive bladder cancer. Herein, we reported our experience with intravesical Gemcitabine in a group of patients affected by high-grade transitional cell carcinoma (TCC) of the bladder. Materials and Methods We retrospectively analyzed a total of 17 patients (15 males and 2 females), affected by high-risk superficial bladder cancer, who were refractory, intolerant or not eligible to intravesical BCG immunotherapy. Each patient received 2000 mg of Gemcitabine diluted in 100 mL of 0.9% saline solution, administered twice a week for 6 weeks. At start, TCC stage and grade were: CIS in 10 patients, TaG3 in 5 and T1G3 in the remaining 2 cases. Those with no macroscopic lesion and negative cytology and histology were considered as complete responders; those with only positive cytology as partial responders, and those with positive biopsy or evidence of macroscopic lesions as non-responders. Results Patients’ mean age was 71.5 yrs (± 7.3 yrs standard deviation). Overall, median follow-up was 12 months [interquartile range (IQR) 9–15 months]. A complete remission was achieved in 10 cases (58.8%), a partial response in 2 (11.8%), while 5 patients (29.4%) were considered as non-responders. Tumor stage and/or grade progression was observed in 26.7% of the cases. Overall, the 6-month recurrence-free survival was 33.3%. Drug toxicity was relatively low: 2 patients developed a grade II dysuria (NCI-CTC criteria); fever >38° was observed in 1 case. Conclusions Although our experience and follow-up are still rather limited to formulate any conclusive assessment, our study seems to confirm that Gemcitabine could be used as a safe and efficient intravesical chemotherapy agent even in high grade TCCs, representing a promising second-line option in those cases who failed, were intolerant or not eligible to BCG therapy.

Abstract
Significant progress has been made in the standardization of bladder neoplasm classification and reporting. Accurate staging using the American Joint Committee on Cancer/International Union Against Cancer (AJCC/UICC) TNM system is essential for patient management, and has been reinforced by clinical evidence in recent years. It is now recognized that 'superficial' bladder carcinomas are a heterogenous group of tumors with diverse biological and clinical manifestations. The term 'superficial,' therefore, is no longer used for bladder tumor nomenclature. Recognition of diagnostic pitfalls associated with lamina propria invasion is critical for the evaluation of bladder tumor specimens. Neither the 1973 nor the 2004 WHO grading system appears to be useful for predicting the clinical outcome of invasive urothelial carcinoma. This review will discuss recent progress and controversial issues on the staging and substaging of bladder carcinomas. Essential elements for handling and reporting of bladder tumor specimens will also be discussed.

Abstract
BACKGROUND As bladder cancer is a superficial tumor with frequent recurrences, early detection and confirmation of recurrence are important. We evaluated the usefulness of NMP22 BladderChek (NMP22BC) for the diagnosis and monitoring of bladder cancer. METHODS From July to December 2004, we enrolled in the study 670 patients who visited the urology clinic in Ewha Womans University, Dongdaemun Hospital with hematuria or dysuria and were tested with NMP22BC. We also performed the NMP22BC and BTA stat tests simultaneously in 21 patients and interference test in 10 patients. RESULTS NMP22BC tests were negative in 97% of the patients who had been cured of bladder cancer and were positive in 95% of the patients with recurred bladder cancer. The diagnostic sensitivity, specificity, positive and negative predictive value, and efficiency were 95.0%, 91.5%, 25.7%, 99.8%, and 91.6%, respectively, with 8.5% false positive and 5% false negative rates. Fifty-five patients showed false positive in the NMP22BC test, the main cause of which was the presence of WBCs in urine. There was a good agreement between the NMP22BC and BTA stat tests (kappa agreement value, 0.5; P=0.008). According to the interference test, two patients with more than 3+ in leukocyte esterase results showed false positive in the NMP22BC test. CONCLUSIONS NMP22BC test was simple to perform, rapid to produce the results, and useful in diagnosing a bladder cancer recurrence; the test shows a high efficiency with a high sensitivity, specificity, negative predictive value, and low false negative rate.

Abstract
OBJECTIVES To determine the biological behaviour of very large superficial bladder tumours (pTa, pT1) and evaluate the impact of the initial tumour weight on long-term prognosis. MATERIAL AND METHODS Of 1569 patients who presented with bladder tumours over a 10-year period, 1070 of the tumours were superficial. Fifty-nine patients had very large tumours (resected weight >or= 15 g). Case notes were analysed to determine recurrence, progression and survival. Median follow-up was 60 months (range 1-156 months). Histological slides were reviewed for all tumours initially reported as pT1 to determine the presence of uninvolved muscle. Statistical analysis was performed using the Kaplan-Meier method to calculate progression and survival estimates. RESULTS The overall progression and recurrence rates for very large superficial bladder tumours were 18% and 68%, respectively. The progression rates for Ta, T1, G1, G2 and G3 tumours were 4%, 28%, 0%, 20% and 50%, respectively, with highest progression rates being seen for pT1G2 and pT1G3 tumours. The progression rate was significantly influenced by initial stage (p=0.01) and grade (p=0.03). Tumour weight did not affect either recurrence, progression or cause-specific survival. There were no differences in progression and survival rates in patients with tumour weights of 15-30 and >30 g (p=0.80 and 0.07, respectively). The review of histology slides of T1 tumours showed that 7/10 cases (70%) with progression had no muscle or an inadequate amount of muscle for definitive staging. Upper urinary tract tumours were seen in only two patients (3.4%). CONCLUSIONS Large size is not an adverse prognostic factor for patients with a superficial bladder tumour. However, these cases are difficult to stage. In view of the high rates of progression and disease-specific mortality, we recommend that very large pT1G2 bladder tumours should be considered as high-risk tumours and targeted for aggressive treatment, including early re-resection, to rule out any occult invasive disease.

Abstract
OBJECTIVE There are limited data on the distribution of bladder cancers in the general population, classified by World Health Organization (WHO)/International Society of Urological Pathology (ISUP) criteria. This study evaluated the classification and stage of bladder cancers as part of a population-based epidemiological study of bladder cancer in the Northeastern United States. MATERIAL AND METHODS All New Hampshire residents with bladder cancer newly diagnosed from 1998 to 2000 were identified through the state cancer registry. All slides were reviewed by a single pathologist. Tumors were classified by two sets of standard criteria. RESULTS The retrieval rate for cases was over 90%. Of 342 cases reviewed, 15 were excluded for technical reasons or because malignancy was not definitively diagnosed. According to WHO/ISUP criteria, 25.7% of tumors were papillary urothelial neoplasms of low malignant potential (PUNLMP), 34.3% low-grade papillary carcinomas, 22.6% high-grade papillary carcinomas, 10.1% non-papillary urothelial carcinomas and 5.5% carcinoma in situ. By WHO (1973) criteria, 52.5% of tumors were grade 1, 21.4% grade 2 and 26.1% grade 3. Two-thirds of all tumors were stage Ta, 20.8% stage T1 and 7.6% stage >or=T2. 100% of PUNLMPs were non-invasive, 6.3% of low-grade carcinomas were invasive and 64.9% of high-grade carcinomas were invasive. CONCLUSIONS Compared to clinic or hospital referral-based series, this study documents a higher percentage of non-invasive tumors and a lower percentage of muscle-invasive tumors. There was also a higher percentage of PUNLMP tumors and fewer high-grade papillary carcinomas than in other series. These results may more accurately reflect prevalence data for bladder cancer grade and stage, although geographic variability may exist.

Abstract
We developed nomograms to predict disease recurrence in patients with Ta, T1 transitional cell carcinoma of the bladder. Thirty-eight training hospitals participated in this retrospective multicenter study. Between 1998 and 2002, a total of 1,587 patients with newly diagnosed non-muscle invasive bladder cancer were enrolled in this study. Patients with prior histories of bladder cancer, non-transitional cell carcinoma, or a follow-up duration of less than 12 months were excluded. With univariate and multivariate logistic regression analyses, we constructed nomograms to predict disease recurrence, and internal validation was performed using statistical techniques. Three-year and five-year recurrence-free rates were 64.3% and 55.3%, respectively. Multivariate analysis revealed that age (hazard ratio [HR]=1.437, p<0.001), tumor size (HR=1.328, p=0.001), multiplicity (HR=1.505, p<0.001), tumor grade (HR=1.347, p=0.007), concomitant carcinoma in situ (HR=1.611, p=0.007), and intravesical therapy (HR=0.681, p<0.001) were independent predictors for disease recurrence. Based on these prognostic factors, nomograms for the prediction of disease recurrence were developed. These nomograms can be used to predict the probability of disease recurrence in patients with newly diagnosed Ta, T1 transitional cell carcinoma of the bladder. They may be useful for patient counseling, clinical trial design, and patient follow-up planning.
