Abstract
Cancer immunotherapy has rapidly become the fourth mainstream treatment alternative after surgery, radiotherapy, and chemotherapy, with some promising results. It aims to kill tumor cells by mobilizing or stimulating cytotoxic immune cells. However, the clinical applications of tumor immunotherapies are limited owing to a lack of adequate delivery pathways and high toxicity. Recently, nanomaterials and genetic engineering have shown great potential in overcoming these limitations by protecting the delivery of antigens, activating targeted T cells, modulating the immunosuppressive tumor microenvironment, and improving the treatment efficacy. Bacillus Calmette-Guérin (BCG) is a live attenuated Mycobacterium bovis vaccine used to prevent tuberculosis, which was first reported to have antitumor activity in 1927. BCG therapy can activate the immune system by inducing various cytokines and chemokines, and its specific immune and inflammatory responses exert antitumor effects. BCG was first used during the 1970s as an intravesical treatment agent for bladder cancer, which effectively improved immune antitumor activity and prevented tumor recurrence. More recently, nano-BCG and genetically engineered BCG have been proposed as treatment alternatives for bladder cancer due to their ability to induce stronger and more stable immune responses. In this study, we outline the development of nano-BCG and genetically engineered BCG for bladder cancer immunotherapy and review their potential and associated challenges.

Abstract
Trained immunity is a functional state of the innate immune response and is characterized by long-term epigenetic reprogramming of innate immune cells. This concept originated in the field of infectious diseases - training of innate immune cells, such as monocytes, macrophages and/or natural killer cells, by infection or vaccination enhances immune responses against microbial pathogens after restimulation. Although initially reported in circulating monocytes and tissue macrophages (termed peripheral trained immunity), subsequent findings indicate that immune progenitor cells in the bone marrow can also be trained (that is, central trained immunity), which explains the long-term innate immunity-mediated protective effects of vaccination against heterologous infections. Although trained immunity is beneficial against infections, its inappropriate induction by endogenous stimuli can also lead to aberrant inflammation. For example, in systemic lupus erythematosus and systemic sclerosis, trained immunity might contribute to inflammatory activity, which promotes disease progression. In organ transplantation, trained immunity has been associated with acute rejection and suppression of trained immunity prolonged allograft survival. This novel concept provides a better understanding of the involvement of the innate immune response in different pathological conditions, and provides a new framework for the development of therapies and treatment strategies that target epigenetic and metabolic pathways of the innate immune system.

Abstract
Purpose The recombinant Bacillus Calmette–Guérin (BCG) containing the streptococcal inhibitor of the complement gene (rBCG-sic) may be more resistant to antimicrobial peptides and improve internalization; therefore, it can enhance the immunotherapeutic effect of the BCG. Here we determined the optimal dose of rBCG-sic and compared its effectiveness with that of BCG. Materials and Methods We fabricated a high-throughput 3D-bioprinted bladder cancer-on-a-chip (BCOC) and used it to evaluate the effectiveness of the rBCG-sic in terms of cell viability, cell migration, and cytokine concentrations. Using an orthotopic mouse model, we evaluated its anticancer effect and toxicity via bioluminescence imaging. Results T24 cell viability was decreased after treatment with rBCG-sic 30 multiplicities of infection (MOI) versus the same dosage of mock BCG (42.8%±6.4% vs. 75.7%±6.6%, p<0.05). THP-1 cell migration was positively correlated with rBCG-sic concentration (2.42-fold at 30MOI, p<0.01). The interleukin-6 concentration of rBCG-sic 30MOI was significantly higher than that of mock BCG 30MOI (11.2±1.3 pg/mL vs. 6.7±0.6 pg/mL, p<0.05). In the orthotopic bladder cancer mouse model, lower tumor volume was observed in the rBCG-sic 30MOI group than in the BCG 30MOI group after 10 days of treatment (p<0.05). Conclusions We concluded that rBCG-sic is a useful tool for overcoming BCG unresponsiveness in non-muscle invasive bladder cancer. Additionally, high-throughput BCOC with a microfluidic system can successfully reflect the bladder cancer microenvironment.

Abstract
Immunotherapy of bladder cancer is known to have favorable effects, although it is difficult to determine which patients will show a good response because of the different tumor microenvironments (TME). Here, we developed a bladder cancer-on-a-chip (BCOC) to mimic the TME using three-dimensional (3D) bioprinting and microfluidic technology. We fabricated a T24 and a 5637-cell line-based BCOC that also incorporated MRC-5, HUVEC, and THP-1 cells. We evaluated the effects of TME and assessed the immunologic reactions in response to different concentrations of Bacillus Calmette–Guérin (BCG) via live/dead assay and THP-1 monocytic migration, and concentrations of growth factors and cytokines. The results show that cell viability was maintained at 15% filling density in circle-shaped cell constructs at 20 μL/min microfluidic flow rate. A 3D co-culture increased the proliferation of BCOCs. We found that the appropriate time to evaluate the viability of BCOC, concentration of cytokines, and migration of monocytes was 6 h, 24 h, and three days after BGC treatment. Lastly, the immunotherapeutic effects of BCOC increased according to BCG dosage. To predict effects of immunotherapeutic agent in bladder cancer, we constructed a 3D bioprinted BCOC model. The BCOC was validated with BCG, which has been proven to be effective in the immunotherapy of bladder cancer.

Abstract
PURPOSE Programmed cell death-1 ligand-1 (PD-L1) expression has been associated with prognostic implications in urologic malignancies. We aimed to investigate prognostic significance of pre- and post-treatment PD-L1 expression in patients treated with BCG for high-grade non-muscle-invasive bladder cancer (NMIBC). METHODS We reviewed a total of 141 high-grade NMIBC cases treated with transurethral resection + ≥ 6 BCG instillations between 2004 and 2017. PD-L1 immunohistochemistry (IHC) scoring was done on 0-3 scale, and cut-off for positive and high-level PD-L1 expression was set to ≥ 1% and ≥ 5% staining of tumor-infiltrating immune cells (IC), respectively. Clinicopathologic characteristics and oncologic outcomes [recurrence-free (RFS) and progression-free survival (PFS)] were compared, stratified by PD-L1 positivity. The prognostic role of PD-L1 was assessed using Kaplan-Meier, and univariate and multivariate Cox regression analyses. RESULTS Pre-treatment, 46.2% and 6.8% of high-grade NMIBC demonstrated positive and high-level PD-L1 expression, respectively. Positive PD-L1 expression was associated with submucosal invasion and refractory-tumor recurrence. PD-L1 expression was not associated with RFS or PFS in regression analysis. Post-treatment, 55.1% and 11.6% of recurrent tumors demonstrated positive and high-level PD-L1 expression, respectively. Down-regulation of PD-L1 expression was noted in patients with refractory recurrence (p = 0.012). CONCLUSION Pre-treatment PD-L1 expression was associated with unfavorable pathological features in primary high-grade NMIBC and its expression level after BCG immunotherapy was significantly decreased in patients with refractory recurrence. PD-L1 expression did not have prognostic value for PFS or RFS; therefore, further research is necessary to identify novel biomarkers for prediction of disease outcomes in high-grade NMIBC.

Abstract
BACKGROUND Urothelial carcinoma (UC) is a common malignancy with a high mortality rate when metastatic. Traditionally, systemic therapy consisted in platinum-based regimens as first-line, with Taxanes or Vinflunine as further lines. Recently, checkpoint inhibitors (CPIs) immunotherapy has emerged as a new therapeutic option. METHODS We searched in Medline, Pubmed and ClinicalTrial.gov databases for the relevant literature, reviewing the results of published trials and the design of ongoing studies involving CPIs in UC. RESULT Strong evidence supports the use of CPIs after failure of Cisplatin-based chemotherapy, although no predictive parameter is available so far. Expression of Programmed-Death-1-Ligand has given conflicting results, and is currently indicated only for the selection of Cisplatin-ineligible patients who should receive CPIs. CONCLUSION The therapeutic landscape of UC is rapidly changing due to the availability of CPIs. Neoadjuvant trials with CPIs and trials combining two CPIs are promising and will further expand the use of immunotherapy.

Abstract
Purpose To analyse if BCG treatment leads to long-term reduction of recurrence, progression, and cancer-specific mortality (CSM) in patients with high-risk NMIBC. Materials and methods 140 patients with high-risk NMIBC were drawn from a population-based cohort of 538 patients with newly diagnosed bladder cancer in the Stockholm County between 1995 and 1996. Data were collected prospectively, and a final follow-up for recurrence, progression, and CSM was performed after 15 years. Patients that received BCG were compared with patients who did not receive BCG. Survival analysis was done with Kaplan–Meier estimates and Mantel–Cox log-rank test. Multivariable Cox proportional regression with stepwise selection was performed to verify the statistical significance of clinicopathological factors of prognostic importance. Results were displayed in Hazard ratios and a p < 0.05 was considered to be statistically significant. Results With a median follow-up of 100 months (2–182), 76 patients recurred; 50 progressed to muscle invasion; and 92 died of whom 38 died from bladder cancer. After 15-year follow-up, there was a statistically significant reduction in rate for recurrence (HR 0.40, p < 0.0001) and progression (HR 0.52, p = 0.038), but not for CSM, in patients that received BCG compared to those who did not. Conclusions In this group, BCG in high-risk NMIBC patients reduced the long-term risk of recurrence and progression. The effect on CSM is yet to be clarified.

Abstract
In the present study we tested the role of Human Epidermal Growth Factor Receptor-2 (HER-2) expression, as assayed by immunohistochemistry, in predicting recurrence and progression in 67 patients with T1G3 BC having undergone transurethral resection of bladder tumor (TURBT) alone (33) or TURBT + Bacillus Calmette Guerin (BCG) instillations (34). All patients had a negative restaging TURBT within 4 months after the first TURBT. At median follow-up of 75.7 months, the overall disease-free and progression-free rates were 35.8% and 73.0%, respectively. Univariate Kaplan-Meier survival analysis showed that traditional prognostic factors (sex, tumor number/size/recurrence) failed to predict disease-free and progression free survival (DFS, PFS). BCG treatment was a significant predictor of DFS (p=0.0231) but not of PFS (p=0.6901). HER-2 overexpression was a significant predictor of DFS (p=0.0013) and PFS (p=0.0322) in the overall patients population, but failed to predict PFS when patients were stratified for treatment (BCG: p=0.1290; no BCG: p=0.1696) probably due to the limited number of events. Multivariate Cox proportional-hazards regression analysis confirmed that BCG treatment was a significant predictor of DFS (p=0.012) but not of PFS (p=0.924), whereas HER-2 overexpression was a significant predictor of DFS (p=0.001) and PFS (p=0.041). These findings suggest that HER-2 status performs better than "traditional" prognostic factors as well as of BCG treatment in predicting the outcome of T1G3 BC, thus providing grounds for further testing this marker and possibly incorporating it in a panel of molecular markers that could reliably predict the behavior of this challenging disease.

Abstract
BACKGROUND Recurrence and progression of T1 grade 3 (T1G3) urothelial bladder carcinomas (UBCs) treated with bacille Calmette-Guérin (BCG) are common events, but the long-term follow-up of the disease remains controversial. OBJECTIVE To evaluate the long-term outcomes of BCG intravesical therapy in relation to disease recurrence and progression in primary T1G3 UBCs and upper tract disease. PATIENTS AND METHODS A single-institution, retrospective, population-based analysis of 316 patients with primary T1G3 UBC treated with transurethral resection (TUR) and BCG induction intravesical instillations was performed. Response was determined and monitored by routine periodic urine cytology, cystoscopy, and upper tract imaging. RESULTS The median follow-up was 70 months (maximum 210 months). Among all of the tumours, 49.4 % did not relapse, 48.7 % recurred in the bladder during the first 5 years of surveillance, and only 6 patients (1.9 %) recurred after being free of disease during the first 5 years of follow-up. Nineteen percentage of the UBCs progressed to stage T2, and only 2 patients (1.2 %) progressed after the first 5 years of surveillance. An upper urinary tract recurrence was detected in 9.2 % of the patients; 65.5 % were diagnosed within the upper urinary tract during the first 5 years of follow-up. CONCLUSIONS Following a 5-year tumour-free period, there is minimal risk of recurrence and progression in T1G3 UBCs treated with TUR and BCG induction intravesical instillations. This finding supports a less intensive and potentially less invasive surveillance scheme of bladder follow-up and upper urinary tract imaging in patients without any recurrence.

Abstract
Hyperthermia represents a unique, safe, and advantageous methodology for improving therapeutic strategies in the management of bladder cancer. This modality has shown promise in contributing to treatment regimens for both superficial and muscle-invasive disease. Especially in conjunction with intravesical chemotherapy, systemic therapy, and radiotherapy, hyperthermia shows particular synergistic benefit. As such, it should be explored further through clinical use and clinical trial in conjunction with currently available techniques and emerging technologies. However, to conceptualise the way forward, it is particularly important to understand the current challenges to widespread use of non-invasive, bladder-sparing approaches and the current state of bladder cancer care. As such, in the following article, we have focused on not only the rationale for concurrent radiotherapy and hyperthermia, but also the clinical landscape in bladder cancer as a whole.

Abstract
Background Recently, it has been shown that 5-fluorouracil (5-FU) with a strong dihydropyrimidine dehydrogenase (DPD) inhibitor elicits a significant response in bladder cancer with a high level of DPD. However, only a few studies investigated the association between the level of the enzyme that regulates the metabolism of 5-FU and prognosis in bladder cancer. Furthermore, to our knowledge, there has also been no such report in T1G3 bladder tumors treated with BCG. Therefore, we evaluated enzymes that regulate the metabolism of 5-FU in T1G3 tumors treated with BCG immunotherapy using the Danenberg tumor profile (DTP) method, a highly accurate measurement of RNA from paraffin-embedded specimens. Methods This study included 28 patients with T1G3 bladder cancer, each of whom underwent complete transurethral tumor resection and BCG intravesical instillation at our institution. The median follow-up period was 39 months (range, 3 to 159 months). The DTP method was used to analyze the mRNA expression of 3 enzymes related to 5-FU: DPD, orotate phosphoribosyltransferase (OPRT), and thymidylate synthase (TS). Results Among the 28 patients, 13 developed recurrences (46.4%) and 5 experienced disease progression (17.9%). An elevated DPD mRNA level was significantly associated with recurrence (p = 0.048) and progression (p = 0.045). However, TS and OPRT mRNA levels were not significantly associated with any other clinical features or outcomes. Furthermore, the high DPD group had a significantly lower recurrence-free survival rate than the low DPD group (p = 0.047). Among patients with low DPD, the 2- and 5-year recurrence-free survival rates were 88.9% and 74.1%, respectively; while among patients with high DPD, the corresponding rates were 61.3% and 36.8%, respectively. TS and OPRT were not significantly associated with recurrence-free survival rates. Conclusion DPD is significantly associated with recurrence and progression among T1G3 bladder cancer patients treated with BCG.

Abstract
The management of T1G3 bladder cancer is controversial. Diagnostic methods, such as bladder mapping or second-look transurethral resection are recommended to assess risk. Bacillus Calmette-Guérin intravesical therapy with a maintenance regimen is recommended for solitary T1G3 tumors. The timing of radical cystectomy for these patients is controversial, but early recurrence during intravesical therapy is an indication for radical cystectomy. Multifocal disease, concomitant carcinoma in situ and disease in the prostatic urethra and bladder neck also suggest aggressive disease and cystectomy should be considered in these patients.

Abstract
BACKGROUND Bacillus Calmette-Guérin (BCG) is a standard treatment to reduce tumor recurrence and delay progression of high-risk non-muscle-invasive (NMI) bladder tumors. However, it is not clear yet which patients are more likely to respond to BCG. OBJECTIVE The aim was to evaluate the role of polyamine-modulated factor-1 (PMF-1) methylation in predicting clinical outcome of T1 high-grade (T1HG) bladder tumors treated with BCG. DESIGN, SETTING, AND PARTICIPANTS In a retrospective design, PMF-1 methylation was analyzed on tumor specimens belonging to 108 patients with T1HG NMI bladder cancer undergoing BCG treatment. Median follow-up was 77 mo (range: 5-235 mo). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS PMF-1 methylation was assessed by methylation-specific polymerase chain reactions. Recurrence, progression into muscle-invasive tumors, and disease-specific survival rates were analyzed using competing risks regression analysis. RESULTS AND LIMITATIONS Among the 108 patients analyzed, 35 had recurring disease (32.4%), 21 progressed (19.4%), and 16 died of disease (14.8%); 71.3% of tumors had PMF-1 methylation. Univariate analyses using cumulative incidence curves revealed that an unmethylated PMF-1 was significantly associated with increased recurrence (p=0.026), progression (p=0.01), and shorter disease-specific survival (log-rank, p=0.03). Multivariate analyses indicated that among sex, age, focality, tumor size, and concomitant carcinoma in situ, only PMF-1 methylation provided significant hazard ratios (HRs) for recurrence of (HR: 2.032; p=0.042), and progression (HR: 2.910; p=0.020). Limitations of the study include its retrospective design, lymphovascular invasion status not available, short maintenance BCG, and that a second transurethral resection was not performed. CONCLUSIONS Epigenetic analyses revealed that the methylation status of PMF-1 was associated with the clinical outcome of patients with T1HG tumors undergoing BCG treatment. An unmethylated PMF-1 correlated to recurrence and progression in T1HG disease using univariate and multivariate analyses. Thus, assessing the methylation status of PMF-1 may serve to distinguish patients responding to BCG from those who may require more aggressive therapeutic approaches.

Abstract
Transurethral resection is an effective therapy for non-muscle-invasive bladder cancer. However, the high rates of recurrence and significant risk of progression in higher grade tumors mandates additional therapy with intravesical agents. In this review we discuss the role of various intravesical agents currently in use including the immunomodualtory agent BCG and chemotherapeutic agents. We discuss the current guidelines and the role of these therapeutic agents in the context of higher grade Ta and T1 tumors.

Abstract
Up to 40% of patients with non-muscle-invasive bladder cancer (NMIBC) will fail intravesical bacillus Calmette-Guérin (BCG) therapy. There is unfortunately no current gold standard for salvage intravesical therapy after appropriate BCG treatment. Indeed, outcomes are at best suboptimal. The vast majority of low-grade NMIBC are prone to recur but very rarely progress. Failure after intravesical BCG in these patients is usually superficial and low-grade. At the other end of the spectrum, failure to respond to BCG in high-risk T1 bladder cancer and/or carcinoma in situ (CIS or TIS) is more problematic, since those tumours often have the potential to progress to muscle invasion. In these cases, radical cystectomy remains the mainstay after BCG failure. With appropriate selection, certain patients who "fail" BCG (but with favourable risk factors) can be managed with intravesical regimens, including repeated BCG, BCG plus cytokines, intravesical chemotherapy, thermochemotherapy or new immunotherapeutic modalities. In this review, reasons explaining BCG failure, how to define BCG failure, optimal risk stratification and prediction of response and management of BCG failures are discussed.

Abstract
OBJECTIVE To report the long-term results of bacille Calmette-Guérin (BCG) intravesical therapy in relation to disease progression and recurrence in primary T1 high-grade (HG) bladder cancer (BC) confirmed by central pathological review. PATIENTS AND METHODS In all, 136 patients from two university centres (Rotterdam, n = 49; Toronto, n = 87) were diagnosed with primary T1HG BC. One experienced uro-pathologist reviewed all slides, ensuring all cases were indeed HG and that muscle was present in all specimens. Patients were treated with BCG induction (six instillations) after transurethral resection (TUR) of the tumour and followed with cystoscopy and urinary cytology. Predictors for recurrence, progression and survival were assessed with multivariable Cox regression models. RESULTS Mean (range) follow-up was 6.5 (0.3-21.6) years. There were no significant differences for recurrence (P = 0.52), progression (P = 0.35) and disease-specific survival (DSS) (P = 0.69) between the two centres. Among the cohort, 47 patients (35%) recurred and 42 (30.9%) progressed with a median time to progression of 2.1 years; 16 (38%) of these progressions occurred ≥ 3 years after the initial BCG course; 22 (16%) patients who progressed died from BC. Overall, 96 (71%) patients had no evidence of disease at the last follow-up. Carcinoma in situ was the only independent predictor for recurrence in multivariate analysis (P = 0.011). No independent predictors were found for progression. CONCLUSIONS Conservative treatment with BCG is a valid option in primary T1HG BC. Nevertheless, the aggressive nature of T1HG BC is evident in the fact that 30% progressed, with a high proportion of these progression events occurring ≥ 3 years after BCG. Caution should be exercised when relying on the long-term effects of BCG, and close follow-up of these patients should not be neglected.

Abstract
PURPOSE Bacillus Calmette-Guerin is standard treatment to decrease tumor recurrence and delay progression of high risk, nonmuscle invasive bladder tumors. However, it is not yet clear which T1G3 cases are more prone to more aggressive clinical behavior or susceptible to respond to bacillus Calmette-Guerin. We evaluated the role of myopodin methylation as a clinical outcome prognosticator and predictive biomarker for the bacillus Calmette-Guerin response in patients with T1G3 bladder tumors. MATERIALS AND METHODS We analyzed the methylation status of myopodin in tumor specimens from 170 patients with T1G3 bladder cancer, including a subset of 108 who underwent bacillus Calmette-Guerin treatment. Myopodin methylation was assessed by methylation specific polymerase chain reactions. Recurrence, progression to muscle invasive tumors and disease specific overall survival were analyzed using competing risks regression analysis. RESULTS Of the 170 cases analyzed 72 recurred (42.4%) and 36 progressed (21.2%). A total of 24 patients (14.1%) died of the disease. Univariate and multivariate survival analysis revealed that myopodin methylation was significantly associated with an increased recurrence rate (p = 0.004), progression (p = 0.002) and shorter disease specific overall survival (p = 0.020). In a subset treated with bacillus Calmette-Guerin myopodin methylation was also related to an increased recurrence rate (p = 0.011), progression (p = 0.030) and shorter disease specific overall survival (p = 0.028). CONCLUSIONS Epigenetic analysis revealed that myopodin methylation was associated with tumor aggressiveness and clinical outcome in patients with T1G3 disease. Myopodin methylation distinguished patients responding to bacillus Calmette-Guerin from those who may require a more aggressive therapeutic approach.

Abstract
CONTEXT This review focuses on the prediction of recurrence and progression in non-muscle invasive bladder cancer (NMIBC) and the treatments advocated for this disease. OBJECTIVE To review the current status of epidemiology, recurrence, and progression of NMIBC and the state-of-the art treatment for this disease. EVIDENCE ACQUISITION A literature search in English was performed using PubMed and the guidelines of the European Association of Urology and the American Urological Association. Relevant papers on epidemiology, recurrence, progression, and management of NMIBC were selected. Special attention was given to fluorescent cystoscopy, the new World Health Organisation 2004 classification system for grade, and the role of substaging of T1 NMIBC. EVIDENCE SYNTHESIS In NMIBC, approximately 70% of patients present as pTa, 20% as pT1, and 10% with carcinoma in situ (CIS) lesions. Bladder cancer (BCa) is the fifth most frequent type of cancer in western society and the most expensive cancer per patient. Recurrence (in < or = 80% of patients) is the main problem for pTa NMIBC patients, whereas progression (in < or = 45% of patients) is the main threat in pT1 and CIS NMIBC. In a recent European Organisation for Research and Treatment of Cancer analysis, multiplicity, tumour size, and prior recurrence rate are the most important variables for recurrence. Tumour grade, stage, and CIS are the most important variables for progression. Treatment ranges from transurethral resection (TUR) followed by a single chemotherapy instillation in low-risk NMIBC to, sometimes, re-TUR and adjuvant intravesical therapy in intermediate- and high-risk patients to early cystectomy for treatment-refractory high-risk NMIBC. CONCLUSIONS NMIBC is a heterogeneous disease with varying therapies, follow-up strategies, and oncologic outcomes for an individual patient.

Abstract
BACKGROUND Bacillus Calmette-Guérin (BCG) is a standard treatment for reducing tumour recurrence and delaying progression of high-risk, non-muscle-invasive bladder tumours. However, it is not clear yet which patients are more likely to be responders to BCG. OBJECTIVE To evaluate the role of ezrin expression in bladder cancer (BCa) progression in T1G3 bladder tumours treated with BCG. DESIGN, SETTING, AND PARTICIPANTS Ezrin protein expression patterns were analysed on tumour specimens belonging to 92 patients with T1G3 non-muscle-invasive BCa undergoing nonmaintenance BCG treatment. Re-resection was not performed. The median follow-up was 90.5 mo (range: 3.0-173.0). A specific tissue array was created containing three representative cores of each of the tumour specimens belonging to these patients. MEASUREMENTS Ezrin protein expression patterns were assessed by immunohistochemistry on this tissue array. Proliferation rates were assessed by means of Ki67 staining. Recurrence, progression into muscle-invasive tumours, and disease-specific overall survival (OS) rates were analysed using univariate and multivariate tests. RESULTS AND LIMITATIONS Among the 92 patients analysed, 40 recurred (43.5%), 17 progressed (18.5%), and 14 died of the disease (15.2%). Log-rank survival analyses revealed that an ezrin membrane expression <20% was significantly associated with increased progression (p=0.009) and shorter disease-specific OS (p=0.006). Multivariate analyses showed that ezrin was an independent prognostic marker of progression (p=0.031) and disease-specific survival (p=0.035). Interestingly, the low ezrin membrane expression correlated with high proliferation rates (p=0.033). CONCLUSIONS Immunohistochemistry analyses revealed that the membrane expression of ezrin is associated with the clinical outcome of patients with T1G3 tumours undergoing BCG treatment. Protein expression patterns of ezrin were associated with tumour progression in T1G3 disease. The differential expression of ezrin distinguished patients responding to BCG from those who may require a more aggressive therapeutic approach.

Abstract
Muscle invasive bladder cancer is still an interdisciplinary problem for urologists, oncologists and radiotherapists. Our efforts should be on finding the right time for the right intervention such as radical cystectomy or chemotherapy and/or irradiation. New forms of diagnostics and therapies are now available, or at least in clinical trails, to make therapy more effective.

Abstract
2-Arylidenedihydroindole-3-ones were assayed for their antiproliferative and apoptotic abilities as potential drug candidates to treat bladder tumor. These compounds were tested on cell lines obtained from bladder tumors of various stages [superficial (pTa and pT1) vs. invasive (pT2)]. The most active compound (3c) inhibited the proliferation, induced apoptosis, and decreased the expression of p-Stat5 and p-Pyk2 in DAG-1 and RT112 lines in which the FGFR3 is either mutated or overexpressed. Knowing that FGFR3 is involved in cell proliferation, differentiation, and migration through cell signaling pathways including p-Stat5 way via p-Pyk2, let us assume that compound 3c may probably act through FGFR3 pathway.

Abstract
OBJECTIVES To determine whether intravesical bacillus Calmette-Guérin (BCG) administration reduces recurrence after transurethral resection of superficial bladder cancer using a meta-analysis. METHODS Published data of randomized clinical trials comparing transurethral resection plus intravesical BCG to either resection alone or resection plus another treatment were analyzed, considering possible confounding factors such as disease type, maintenance therapy, and others. Both the fixed effect model and the randomized effect model were applied, and the odds ratio (OR) with its 95% confidence interval (CI) was used as the effect size estimate. RESULTS We searched 176 trials, eliminated 151 of them, and identified 25 trials with recurrence information on 4767 patients. Of 2342 patients undergoing BCG therapy, 949 (40.5%) had tumor recurrence compared with 1205 (49.7%) of 2425 patients in the non-BCG group. In the combined results, a statistically significant difference in the OR for tumor recurrence between the BCG and no BCG-treated groups was found (randomized combined effect OR 0.61, 95% CI 0.46 to 0.80, P <0.0001). Stratified by BCG maintenance and disease type, the combined results of the individual reports showed statistical significance for BCG maintenance (OR 0.47, 95% CI 0.28 to 0.78, P = 0.004) and treatment of papillary carcinoma (OR 0.50, 95% CI 0.33 to 0.75, P = 0.0008). Chemotherapy and BCG plus chemotherapy/immunotherapy were not better than BCG alone. CONCLUSIONS Adjuvant intravesical BCG with maintenance treatment is effective for the prophylaxis of tumor recurrence in superficial bladder cancer. For patients with papillary carcinoma, adjuvant intravesical BCG with maintenance therapy should be offered as the treatment of choice.

Abstract
OBJECTIVE Review management of bacillus Calmette-Guérin (BCG) failures in superficial bladder cancer. METHOD Search of published literature and meeting abstracts. RESULTS Patients in whom BCG fails are not a uniform group. Failure cannot be predicted but high-risk patients can be identified. In case of failure and progression the outcome is bad. Conservative but investigative alternatives are BCG/interferon-alpha, intravesical hyperthermia/chemotherapy, or photodynamic therapy. Standard treatment in failing patients remains cystoprostatectomy. CONCLUSION BCG failures need careful and individualized therapy in experienced hands.

Abstract
T1G3 tumours are the most aggressive superficial tumours of the bladder, with a high risk of recurrence and progression. Complete endoscopic resection of the tumour is the first diagnostic and therapeutic step in T1G3 management. A second resection should be done at 1 month to avoid residual tumour and misdiagnosis of a muscle infiltrative cancer. As a result of treatment by instillations of Calmette and Guérin bacillus following endoscopic resection, a 5-year survival rate of 80% has been reported, with 50 to 60% of bladder preservation. BCG is the only conservative treatment that has proven effectiveness on both tumour recurrence and progression. Long term protocols seem to give the best results. Endovesical chemotherapy is not commonly used as its impact on progression has not been demonstrated. Radical cystectomy can be chosen as first line treatment in patients with particularly aggressive tumours. Long term and close surveillance should be achieved in every patient.

Abstract
Despite remarkable progress in therapeutic options for the management of bladder cancer, it remains a challenge for urologists to achieve successful outcomes in the treatment of both superficial and invasive bladder cancers. In this review, recent advances in the field of antisense oligodeoxynucleotide therapy targeting several genes playing functionally important roles in the progression and recurrence of bladder cancer are summarized. Data showing the synergistic antitumor activities of antisense oligodeoxynucleotide therapy, combined with several treatments, including cytotoxic chemotherapy, radiation and other molecular targeting therapies, are also presented. Finally, the future direction of antisense oligodeoxynucleotide therapy in the therapeutic strategy of bladder cancer is discussed. These findings may help clarify the significance of antisense oligodeoxynucleotide therapy as an attractive alternative to conventional strategies.

Abstract
OBJECTIVES To provide tables that allow urologists to easily calculate a superficial bladder cancer patient's short- and long-term risks of recurrence and progression after transurethral resection. METHODS A combined analysis was carried out of individual patient data from 2596 superficial bladder cancer patients included in seven European Organization for Research and Treatment of Cancer trials. RESULTS A simple scoring system was derived based on six clinical and pathological factors: number of tumors, tumor size, prior recurrence rate, T category, carcinoma in situ, and grade. The probabilities of recurrence and progression at one year ranged from 15% to 61% and from less than 1% to 17%, respectively. At five years, the probabilities of recurrence and progression ranged from 31% to 78% and from less than 1% to 45%. CONCLUSIONS With these probabilities, the urologist can discuss the different options with the patient to determine the most appropriate treatment and frequency of follow-up.

Abstract
PURPOSE We determined if a third of the dose of intravesical bacillus Calmette-Guerin (BCG) has the same efficacy than a standard dose for decreasing the risk of recurrence and progression after transurethral resection in patients with superficial high risk (stages T1G3 and carcinoma in situ) bladder cancer. Also, we evaluated toxic side effects. MATERIAL AND METHODS A total of 155 patients with a mean age +/- SD of 67 +/- 10.1 years with superficial bladder cancer, including stages T1G3 in 90, a Tis primary tumor in 23 and associated Tis disease in 42, were enrolled and randomly assigned to be treated after transurethral resection of all visible lesions with intravesical BCG, Connaught strain (weekly x 6 and fortnightly x 6 thereafter) with the standard dose of 81 mg or with the decreased dose of 27 mg. RESULTS Median followup was 61 months (range 3 to 102). Disease recurred in 32 patients (39%) treated with the standard dose and in 33 (45%) treated with the decreased dose. Median time to recurrence was not attained in the standard dose arm and it was 63 months in the decreased dose arm. Kaplan-Meier estimates for time to recurrence did not reveal differences between the 2 doses (p = 0.405). Tumor progressed in 20 patients (24.7%) with the standard dose and in 19 (26%) with the decreased dose. Four patients (6.1%) with Tis had local extension into the prostatic urethra and ducts, including 3 (8.3%) treated with the standard dose and 1 (3.4%) treated with the decreased dose. Median time to progression was not attained in either arm. Kaplan-Meier estimates for time to progression did not differ significantly (p = 0.7997). Deferred cystectomy for progression was performed in 7 patients (8.4%) treated with the standard dose and in 7 (9.5%) of those treated with the decreased dose. Subgroup analysis by patient age, tumor status, number, size and T stage (T1G3 vs Tis) did not differ significantly. The groups did not differ in disease specific mortality, which was 12.2% in the standard dose arm and 16.4% in the decreased dose arm. Mean disease specific survival +/- SE was 86.96 +/- 4.14 and 83.73 +/- 4.73 months, respectively. CONCLUSIONS Our results suggest that a 3-fold decreased dose of intravesical BCG is as effective as the standard dose against progression in patients with high risk stages T1G3 and Tis superficial bladder carcinoma but with significantly less toxicity.

Abstract
In this essay I suggest that the major difficulty in producing effective anti-cancer vaccines lies in the fact that most cancers have little immunogenicity because of a basic paucity of tumor-specific antigenicity. The lack of antigenicity, despite extensive genomic instability, could be explained if most tumor mutations occur in silenced genes. A further problem is that an immune reaction against tumor antigens, especially in moderate or low amount, may be stimulatory rather than inhibitory to tumor growth.

Abstract
As no prospective randomised studies are available on therapy and outcome in T1G3 carcinoma of the urinary bladder, a decision on therapy can only be made on the basis of retrospective studies or with reference to the individual experience of a particular urologist. In this paper the advantages and disadvantages of primary cystectomy and of transurethral resection, both alone and in combination with BCG instillation, are discussed and compared.

Abstract
PURPOSE OF REVIEW To analyse recent advances in intravesical instillation therapy for superficial bladder cancer. RECENT FINDINGS Although intravesical bacillus Calmette-Guérin has been used for many years in the treatment of superficial bladder cancer, its mechanism of action remains unclear, its poor tolerance remains a problem, the prediction of its efficacy has still to be validated, and its long-term effects on progression and survival are controversial. The exact timing and place of intravesical chemotherapy needs to be better defined, as well as the place of some new molecules. Finally, new approaches need to be explored for overcoming the limitations of the usual intravesical agents. SUMMARY No dramatic advances have been made in understanding the mechanisms of action of bacillus Calmette-Guérin during the past year. However, a careful dissection of this complex immunological pathway continues and immunological criteria are promising for predicting the response to bacillus Calmette-Guérin. Evidence has been accumulating to suggest that a dose reduction during the initial treatment remains effective and reduces side-effects. In addition, bacillus Calmette-Guérin maintenance therapy is useful for high-risk patients. However, long-term tolerance remains an important issue, and the optimal protocol has not yet been defined. On the other hand, it has been proved that intravesical chemotherapy, when administered early after transurethral resection, is effective in preventing frequent recurrences, whereas maintenance chemotherapy is ineffective. Finally, new approaches, including instillations of activated immune cells or targeted gene therapy, are being explored.
