Abstract
Intravesical immunotherapy with Bacillus Calmette-Guerin (BCG) is a standard of care therapy for non-muscle invasive bladder cancer (NMIBC), which accounts for about 75% of newly diagnosed urothelial cancer. However, given the frequent recurrence and progression, identification of a pre-treatment biomarker capable of predicting responsiveness to BCG in NMIBC is of utmost importance. Herein, using multiparametric flow cytometry, we characterized CD8+ T cells from peripheral blood and tumor tissues collected from 27 pre-BCG patients bearing NMIBC to obtain immune correlates of bladder cancer prognosis and responsiveness to BCG therapy. We observed that intratumoral CD8+ T cell subsets were highly heterogenous in terms of their differentiation state and exist at different proportions in tumor tissues. Remarkably, among the different CD8+ T cell subsets present in the tumor tissues, the frequency of the terminally exhausted-like CD8+ T cell subset, marked as PD1+CD38+Tim3+ CD8+ T cells, was inversely correlated with a favorable outcome for patients and a responsiveness to BCG therapy. Moreover, we also noted that the intratumoral abundance of the progenitor exhausted-like PD1+CD8+ T cell subset in pre-BCG NMIBC tumor tissues was indicative of better recurrence-free survival after BCG. Collectively, our study led to the identification of biomarkers that can predict the therapeutic responsiveness of BCG in NMIBC.

Cole K, Al-Kadhimi Z, Talmadge JE. Highlights into historical and current immune interventions for cancer. Int Immunopharmacol 2023; 117:109882. [PMID: 36848790 PMCID: PMC10355273 DOI: 10.1016/j.intimp.2023.109882] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Revised: 01/24/2023] [Accepted: 01/25/2023] [Indexed: 03/01/2023]
Abstract
Immunotherapy is an additional pillar when combined with traditional standards of care such as chemotherapy, radiotherapy, and surgery for cancer patients. It has revolutionized cancer treatment and rejuvenated the field of tumor immunology. Several types of immunotherapies, including adoptive cellular therapy (ACT) and checkpoint inhibitors (CPIs), can induce durable clinical responses. However, their efficacies vary, and only subsets of cancer patients benefit from their use. In this review, we address three goals: to provide insight into the history of these approaches, broaden our understanding of immune interventions, and discuss current and future approaches. We highlight how cancer immunotherapy has evolved and discuss how personalization of immune intervention may address present limitations. Cancer immunotherapy is considered a recent medical achievement and in 2013 was selected as the "Breakthrough of the Year" by Science. While the breadth of immunotherapeutics has been rapidly expanding, to include the use of chimeric antigen receptor (CAR) T-cell therapy and immune checkpoint inhibitor (ICI) therapy, immunotherapy dates back over 3000 years. The expansive history of immunotherapy, and related observations, have resulted in several approved immune therapeutics beyond the recent emphasis on CAR-T and ICI therapies. In addition to other classical forms of immune intervention, including human papillomavirus (HPV), hepatitis B, and the Mycobacterium bovis Bacillus Calmette-Guérin (BCG) tuberculosis vaccines, immunotherapies have had a broad and durable impact on cancer therapy and prevention. One classic example of immunotherapy was identified in 1976 with the use of intravesical administration of BCG in patients with bladder cancer; resulting in a 70 % eradication rate and is now standard of care. However, a greater impact from the use of immunotherapy is documented by the prevention of HPV infections that are responsible for 98 % of cervical cancer cases. In 2020, the World Health Organization (WHO) estimated that 341,831 women died from cervical cancer [1]. However, administration of a single dose of a bivalent HPV vaccine was shown to be 97.5 % effective in preventing HPV infections. These vaccines not only prevent cervical squamous cell carcinoma and adenocarcinoma, but also oropharyngeal, anal, vulvar, vaginal, and penile squamous cell carcinomas. The breadth, response and durability of these vaccines can be contrasted with CAR-T-cell therapies, which have significant barriers to their widespread use including logistics, manufacturing limitations, toxicity concerns, financial burden and lasting remissions observed in only 30 to 40 % of responding patients. Another, recent immunotherapy focus are ICIs. ICIs are a class of antibodies that can increase the immune responses against cancer cells in patients. However, ICIs are only effective against tumors with a high mutational burden and are associated with a broad spectrum of toxicities requiring interruption of administration and/or administration corticosteroids; both of which limit immune therapy. In summary, immune therapeutics have a broad impact worldwide, utilizing numerous mechanisms of action and when considered in their totality are more effective against a broader range of tumors than initially considered. These new cancer interventions have tremendous potential notability when multiple mechanisms of immune intervention are combined as well as with standard of care modalities.

Abstract
Objectives To compare the outcomes of bladder preservation therapy with early or deferred radical cystectomy (RC) in high-grade non-muscle invasive bladder cancer. Methods Prospectively collected data were obtained for patients undergoing transurethral resection of bladder tumor (TURBT) at a tertiary care center between 2007 and 2018. Patients with a high-grade tumor (HGT1) were divided into three groups, depending on the treatment plan: conservative (GI), early RC (GII), or deferred RC (GIII). Kaplan-Meier analysis was performed to assess the cancer-specific survival (CSS). Results Seventy-one patients were included, and the patients had a median (range) age of 49 (32-72) years. The GI, GII, and GIII groups included 34 (47.9%), 14 (19.7%), and 23 (32.4%) patients, respectively. A significantly lower number of GII patients underwent >2 TURBTs (14.3% vs. 100%, p<0.001). Compared to GIII patients, GII patients had a shorter time to RC from the initial diagnosis (5.7 vs. 36.2 months, p=0.03). Ileal conduit and orthotropic bladder diversions were comparable between both groups, with significantly higher postoperative complications in GIII patients. The median (IQR) follow-up times for the groups were 84 (49-102), 82 (52-112), and 73 (36-89) months, respectively. The five-year and 10-year CSS for GII and GIII patients was 79% vs. 75% and 78% vs. 64%, respectively (log rank=0.19). Conclusion Early RC should be considered an alternative treatment option in selected patients with HGT1 BC with expected longer life expectancy, which may significantly decrease postoperative complications and improve the CSS. However, selection bias in the current retrospective study may influence these outcomes.

Abstract
Bacillus Calmette-Guérin (BCG) immunotherapy for bladder cancer has been used since 1976 when the first evidence of its ability to lower recurrence and progression rates was published. Today, BCG immunotherapy is the choice of care for high-grade non-muscle invasive bladder cancer (NMIBC) after transurethral resection. This article presents indications and procedure of BCG instillations, and outlines the effects on recurrence and progression of NMIBC. The BCG-induced immunity in NMIBC is not yet fully understood. Animal studies point towards BCG inducing specific tumour immunity. We describe the current knowledge of how this immunity is induced, from internalization of BCG bacilli in urothelial cells, to cytokine- and chemokine-mediated recruitment of neutrophils, monocytes, macrophages, T cells, B cells and natural killer cells. In addition, we describe the process of trained immunity, the non-specific protective effects of BCG. Recent studies also indicate that dysbiosis of the urinary microbiome may cause lower urinary tract dysfunction. Side effects of BCG bladder instillations range from common, mild and transient symptoms, such as dysuria and flu-like symptoms, to more severe and rarely occurring life-threatening complications. We review the literature and give an overview of reported incidences and management of BCG infections after intravesical instillation.

Abstract
BACKGROUND High-grade non-muscle-invasive bladder cancer is superficial; nonetheless, it is an aggressive cancer. Proper management strategy selection following transurethral resection between bladder preservation (BP) and radical cystectomy (RC) could result in delayed or excessive treatment. Hence, selecting the optimal treatment modality remains controversial to date. METHODS We searched MEDLINE, The Cochrane Library, EMBASE, China National Knowledge Infrastructure, and Wanfang database through 12 April 2018. Quality and publication bias were assessed using the Newcastle-Ottawa Scale and Begg's/Egger's test. We collected 2-year, 5-year, 10-year, and 15-year survival rate and hazard ratio (HR) for overall survival (OS), cancer-specific survival (CSS), and progression-free survival (PFS). Using the Review Manager 5.2 software, we used the odds ratio (OR) of specific years and HR for meta-analysis. Subgroup analysis was performed by the original tumor state, radical cystectomy timing, bladder preservation modality, and age. RESULTS In total, 11 cohorts with 1735 patients were selected for the meta-analysis. All OR of OS supported BP as a better treatment option; however, all OR of PFS had no significant differences. As for CSS, only the 15-year OR reflected a statistical significance preferring RC. Subgroup analysis showed that BP is more appropriate for patients older than 65 and G3 tumor. Limited data demonstrated that late RC (> 3 months) is more effective compared to early RC (< 3 months) and intravesical Bacillus Calmette-Guerin was not statistically different from that of RC. The mixed BP modalities were significantly better compared to RC in OS and worse in CSS, with both having a very low evidence strength. CONCLUSIONS BP is a superior treatment modality compare to RC, especially for older patients and T1G3 or lower grade tumors. However, the superior BP modality was unclear. Conversely, RC could be a better option for younger patients. More specifically, late RC may be more beneficial but had a very-low-level of evidence. Quality of life should be considered equal to survival outcome; hence, post-treatment follow-up needs to be performed. Prospective randomized studies should be performed to overcome the limitations of this meta-analysis study. REGISTRATION Registration ID is CRD42018093491 .

Abstract
PURPOSE Stage pT1 urothelial bladder cancer (UBC) is characterized as a challenging subentity of urothelial carcinoma with an unforeseeable clinical course. In addition to more or less established clinical and histopathological features, we evaluated the role of epithelial-mesenchymal transition (EMT) marker E-cadherin, shown to be of prognostic value in muscle-invasive disease, regarding the prognosis of stage pT1 high-grade (hg) UBC. METHODS Tissue of 226 stage pT1 hg UBC patients from transurethral resection could be immunostained for E-cadherin. Kaplan-Meier analysis and univariate and multivariate Cox regression analyses regarding progression-free (PFS) and cancer-specific survival (CSS) were performed. RESULTS Aberrant expression of E-cadherin was recognized in 74% of patients. Kaplan-Meier analysis showed that aberrant E-cadherin expression was associated with worse 10-year PFS (62 vs. 90%, p = 0.045). In univariate analysis, aberrant E-cadherin staining, associated carcinoma in situ, grading 3 after WHO classification 1973 and infiltrative growth pattern at the invasion front were the statistically significant predictive factors for worse PFS, only infiltrative growth pattern for CSS. With regard to progression, grading 3 after WHO classification of 1973 (HR 6.49; CI 1.54-27.28, p = 0.011) and infiltrative tumor invasion pattern (HR 2.06; CI 1.10-3.86, p = 0.024) revealed as independent factors for PFS, and there was a trend also for E-cadherin expression (HR 0.45; CI 0.19-1.06; p = 0.068). Regarding CSS, infiltrative tumor growth pattern (HR 3.79; CI 1.67-8.60, p = 0.001) was the only statistically significantly independent predictive factor in multivariate Cox regression analysis. CONCLUSIONS Beside invasion growth pattern and WHO grading 1973 that achieved to be independent prognostic factors, there was a trend for the parameter E-cadherin expression to be of predictive value for PFS in stage pT1 hg urothelial bladder carcinoma after organ-sparing approach. Further studies on genetic level are warranted to define the distinct role of EMT in early-invasive UBC.

Abstract
BACKGROUND Management of high-grade T1 (formerly T1G3) bladder cancer continues to be controversial. Should patients with T1G3 bladder cancer have an immediate radical cystectomy or should they receive intravesical bacillus Calmette-Guérin-preserving bladder? Gemcitabine and cisplatin (GC) adjuvant chemotherapy may help to strike a balance between intravesical and early cystectomy. For purposes of this study, we continue to refer high-grade T1 lesion as "T1G3." OBJECTIVE To evaluate the characteristics and the long-term outcome of GC adjuvant chemotherapy in T1G3 bladder cancer after transurethral resection of bladder tumor (TURBT). MATERIALS AND METHODS We retrospectively reviewed 48 patients who were newly diagnosed with T1G3 bladder cancer between January 2009 and December 2012. A total of 48 patients received 4 cycles of GC adjuvant chemotherapy after TURBT. One month after 4 cycles of GC adjuvant chemotherapy, response was evaluated by re-TURBT. Median follow-up was 59.5 (range: 18-70) months, all patients have been observed for more than 3 years. Salvage cystectomy was recommended for patients with persistent disease and for tumor progression after initial complete response. RESULT Complete response was achieved in 44 (91.7%) patients. Of complete responders, 5 patients experienced recurrence and 5 patients showed progression. The progression rate and disease-specific survival rate were 10.4% and 91.7% at 3 years, respectively. More than 80% of survivors preserved their bladder. Kaplan-Meier curves showed that concomitant carcinoma in situ (CIS) was the only factor that had an influence on progression-free survival (P = 0.022) and disease-specific survival (P = 0.017). Concomitant CIS was the prognostic factor for progression rate and disease-specific survival rate at 3 years (P = 0.008 and P = 0.035). CONCLUSION GC adjuvant chemotherapy is a safe conservative treatment for T1G3 bladder cancer, but effective is really a phase II study. Patients with T1G3 bladder cancer with concomitant CIS should be treated more aggressively because of the high risk of progression.

Abstract
Bacillus Calmette-Guérin (BCG) remains the most effective intravesical therapy for non-muscle invasive bladder cancer but will fail in up to 40% of patients. The ability to identify patients who are least likely to respond to further BCG therapy allows urologists to pursue secondary treatments more likely to convey a recurrence or survival benefit to the patient. We examined the literature to determine what constitutes BCG unresponsive disease. After review, we believe that BCG unresponsive disease should be defined as (1) patients with recurrent high grade T1 disease within 6 months of their primary tumor after at least one course of BCG or patients who have failed at least 2 courses of BCG with either (2) persistent or recurrent pure papillary (Ta) disease within 6 months or (3) persistent or recurrent carcinoma in situ (CIS) within 12 months.

Abstract
Nonmuscle invasive (NMI) urothelial cancer (UC) is associated with varied biological potential. It is characterized by frequent recurrence and progression, which thus worsens the oncological outcome. Nearly three-quarters of NMI UCs recur within 5 years, whereas half can progress during follow-up. Progression is particularly seen in T1 and carcinoma in situ (CIS). Undoubtedly, NMI UC is one of the most expensive cancers to manage. The European Organisation for Research and Treatment of Cancer (EORTC) risk calculator is a commonly used tool for assessing the recurrence and progression potential of a newly diagnosed cancer. The parameters used in the assessment are tumor size and number, pathological stage and grade of the cancer, presence of CIS, and prior recurrence rate. The main advantages of the EORTC tool are its ease of use and the lack of need to run expensive molecular tests. However, reproducibility of pathologic stage and grade is modest, which is a concern to clinicians. Molecular markers have potential for predicting the clinical outcome of NMI UC, given that clinico-pathologic variables are not sufficient for prediction of prognosis in an individual. Significant work has been done in the past 2 decades in understanding the molecular biology of bladder cancer; however, the translational value of this knowledge remains poor. The role for molecular markers in predicting recurrence seems limited because multifocal disease and incomplete treatment are probably more important for recurrence than the molecular features of a resected tumor. Urinary markers have very limited value in prognostication of bladder cancer and are used (mainly as an adjunct to cytology) for detection and surveillance of urothelial cell cancer recurrence. Prediction of progression with molecular markers holds considerable promise. Nevertheless, the contemporary value of molecular markers over clinico-pathologic indexes is limited.

Abstract
This study was conducted to evaluate the utility of pyuria as a predictive marker of bacillus Calmette-Guérin (BCG) treatment for non-muscle-invasive bladder cancer (NMIBC). A cohort of 243 NMIBC patients treated with BCG through intravesical instillation between 1994 and 2007 at the Tokyo Metropolitan Tama Medical Center were enrolled in this retrospective study. Pyuria was defined as urine containing ≥10 white blood cells per high-power field. A total of 30 of the patients with pyuria (30/37, 81%) and 87 patients of those without pyuria (87/206, 42%) exhibited recurrence following BCG treatment. The 3-year recurrence-free survival rate of patients with and without pyuria following BCG treatment was 20 and 62%, respectively. The multivariate Cox proportional hazards regression model indicated that pyuria was an independent predictor of disease recurrence following BCG treatment. Patients with inflammatory NMIBC exhibited resistance to therapy with intravesical instillation of BCG.

Abstract
Non-muscle invasive urothelial carcinoma is a heterogeneous disease that requires the practicing urologist to implement a variety of surgical and non-surgical treatment strategies. The disease course can range from recurrent low grade papillary disease to aggressive disease concerning for progression from initial presentation. Depending on the particular patient and goals of care, treatments similarly span the range from minimally invasive fulgurations to immediate radical cystectomy. For most patients some form of intravesical therapy will bridge the gap between transurethral resections (TUR) and radical surgery. Recent advances in the field continue to emphasize the importance of quality TUR and its strong impact on outcomes. In addition, continued research to optimize intravesical therapies has provided more information about how, when, and in whom these agents should be utilized to enhance their efficacy. This review covers the current state of NMIBC and the standards of care for the management of this disease.

Abstract
Most T1 bladder cancers are high grade and have the potential to progress to muscle invasion and extravesical dissemination. Many studies reported that ∼50% of patients displayed residual tumors when a second transurethral resection was performed 2-6 weeks after the initial resection for patients who were diagnosed with T1 bladder cancer. Furthermore, muscle-invasive disease was detected by the second transurethral resection in 10-25% of those patients. Therefore, a second transurethral resection is strongly recommended for patients newly diagnosed with high-grade T1 bladder cancer in various guidelines. T1 bladder cancers are heterogeneous in terms of progression and prognosis after the second transurethral resection. Optimal management and treatment should be considered for patients with T1 bladder cancer based on the pathological findings for the second transurethral resection specimen. If the second transurethral resection reveals residual tumors, aggressive treatments based on the pathological findings should be performed. Conversely, overtreatment with respect to the tumor status should be avoided. Since the evidence of pathological diagnosis at the second transurethral resection is insufficient and many retrospective studies were carried out before the second transurethral resection era, prospective randomized studies should be conducted.

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
CONTEXT The European Association of Urology (EAU) guidelines panel on Muscle-invasive and Metastatic bladder cancer (BCa) updates its guidelines yearly. This updated summary provides a synthesis of the 2013 guidelines document, with emphasis on the latest developments. OBJECTIVE To provide graded recommendations on the diagnosis and treatment of patients with muscle-invasive BCa (MIBC), linked to a level of evidence. EVIDENCE ACQUISITION For each section of the guidelines, comprehensive literature searches covering the past 10 yr in several databases were conducted, scanned, reviewed, and discussed both within the panel and with external experts. The final results are reflected in the recommendations provided. EVIDENCE SYNTHESIS Smoking and work-related carcinogens remain the most important risk factors for BCa. Computed tomography (CT) and magnetic resonance imaging can be used for staging, although CT is preferred for pulmonary evaluation. Open radical cystectomy with an extended lymph node dissection (LND) remains the treatment of choice for treatment failures in non-MIBC and T2-T4aN0M0 BCa. For well-informed, well-selected, and compliant patients, however, multimodality treatment could be offered as an alternative, especially if cystectomy is not an option. Comorbidity, not age, should be used when deciding on radical cystectomy. Patients should be encouraged to actively participate in the decision-making process, and a continent urinary diversion should be offered to all patients unless there are specific contraindications. For fit patients, cisplatinum-based neoadjuvant chemotherapy should always be discussed, since it improves overall survival. For patients with metastatic disease, cisplatin-containing combination chemotherapy is recommended. For unfit patients, carboplatin combination chemotherapy or single agents can be used. CONCLUSIONS This 2013 EAU Muscle-invasive and Metastatic BCa guidelines updated summary aims to increase the quality of care and outcome for patients with muscle-invasive or metastatic BCa. PATIENT SUMMARY In this paper we update the EAU guidelines on Muscle-invasive and Metastatic bladder cancer. We recommend that chemotherapy be administered before radical treatment and that bladder removal be the standard of care for disease confined to the bladder.

Abstract
BACKGROUND Treatment of patients with stage pT1 urothelial bladder cancer (UBC) continues to be a challenge due to its unpredictable clinical course. Reliable molecular markers that help to determine appropriate individual treatment are still lacking. Loss of aquaporin (AQP) 3 protein expression has previously been shown in muscle-invasive UBC. The aim of the present study was to investigate the prognostic value of AQP3 protein expression with regard to the prognosis of stage pT1 UBC. METHOD AQP 3 protein expression was investigated by immunohistochemistry in specimens of 87 stage T1 UBC patients, who were diagnosed by transurethral resection of the bladder (TURB) and subsequent second resection at a high-volume urological centre between 2002 and 2009. Patients underwent adjuvant instillation therapy with Bacillus Calmette-Guérin (BCG). Loss of AQP3 protein expression was defined as complete absence of the protein within the whole tumour. Expression status was correlated retrospectively with clinicopathological and follow-up data (median: 31 months). Multivariate Cox regression analysis was used to assess the value of AQP3 tumour expression with regard to recurrence-free (RFS), progression-free (PFS) and cancer-specific survival (CSS). RFS, PFS and CSS were calculated by Kaplan-Meier analysis and Log rank test. RESULTS 59% of patients were shown to exhibit AQP3-positive tumours, whereas 41% of tumours did not express the marker. Loss of AQP3 protein expression was associated with a statistically significantly worse PFS (20% vs. 72%, p=0.020). This finding was confirmed by multivariate Cox regression analysis (HR 7.58, CI 1.29 - 44.68; p=0.025). CONCLUSIONS Loss of AQP3 protein expression in pT1 UBC appears to play a key role in disease progression and is associated with worse PFS. Considering its potential prognostic value, assessment of AQP3 protein expression could be used to help stratify the behavior of patients with pT1 UBC.

Predictive biomarkers of bacillus calmette-guérin immunotherapy response in bladder cancer: where are we now? Adv Urol 2012; 2012:232609.

Abstract
The most effective therapeutic option for managing nonmuscle invasive bladder cancer (NMIBC), over the last 30 years, consists of intravesical instillations with the attenuated strain Bacillus Calmette-Guérin (the BCG vaccine). This has been performed as an adjuvant therapeutic to transurethral resection of bladder tumour (TURBT) and mostly directed towards patients with high-grade tumours, T1 tumours, and in situ carcinomas. However, from 20% to 40% of the patients do not respond and frequently present tumour progression. Since BCG effectiveness is unpredictable, it is important to find consistent biomarkers that can aid either in the prediction of the outcome and/or side effects development. Accordingly, we conducted a systematic critical review to identify the most preeminent predictive molecular markers associated with BCG response. To the best of our knowledge, this is the first review exclusively focusing on predictive biomarkers for BCG treatment outcome. Using a specific query, 1324 abstracts were gathered, then inclusion/exclusion criteria were applied, and finally 87 manuscripts were included. Several molecules, including CD68 and genetic polymorphisms, have been identified as promising surrogate biomarkers. Combinatory analysis of the candidate predictive markers is a crucial step to create a predictive profile of treatment response.

Abstract
OBJECTIVE To determine whether a survival difference exists between patients with high grade (HG) cT1 urothelial cell carcinoma (UCC) receiving immediate radical cystectomy (IRC) as opposed to those choosing bladder-sparing therapy. PATIENTS AND METHODS Between January 1990 and August 2010, 349 patients were retrospectively identified with a diagnosis of HG cT1 UCC of the bladder. Patients were divided into two groups: those who underwent IRC and those treated with conservative management (CM), consisting of transurethral resection of the bladder tumour (TURBT) and intravesical therapy. IRC was defined as surgery within 90 days of HG cT1 diagnosis with no intervening transurethral resection (TUR) or intravesical therapy (IVT). Trends in patient selection and cancer-specific survival (CSS) were analyzed over consecutive decades. The primary outcome was to compare CSS among patients during consecutive decades whereby management paradigms shifted from IRC to CM. The secondary outcome was to examine whether patient selection changed over time for each respective intervention. RESULTS One hundred and thirteen patients underwent IRC and 236 had CM. From 1990 to 1999, only 90 patients were diagnosed with HG cT1 disease, and a majority of patients (n= 54) underwent IRC. From 2000 to 2010, only 23% (59/259) of the patients with HG cT1 underwent IRC. Despite 42.3% more patients successfully maintaining their bladder in the long-term, no difference in 5 year bladder CSS was noted between decades (77% vs 80% consecutively, P= 0.566). A subset analysis of risk factors for bladder cancer progression/recurrence demonstrated more patients with lymphovascular invasion (LVI) on TUR underwent IRC in the current era (13/59 (22.0%) vs 13/200 (6.5%), P < 0.001). These findings remain to be validated in prospective work at other institutions. CONCLUSION Conservative management strategies are a viable treatment option within a well selected subset of patients with HG cT1 UCC.

Abstract
OBJECTIVE •To analyze the impact of a delayed radical cystectomy (rCx) and clinical variables on cancer-specific survival (CSS) in patients presenting 'high-risk' carcinoma not invading bladder muscle (nmiBCA). PATIENTS AND METHODS •Between 1989 and 2006, 278 patients who presented 'high-risk' nmiBCA finally underwent rCx in our institution. •CSS was correlated with clinical variables such as the number of transurethral resections of the bladder (TURBs), interval between first TURB and rCx, adjuvant therapies, tumour upstaging at rCx, tumour stage and lymph node (LN) status. RESULTS •The overall 5- and 10-year CSS was 82% and 76%, respectively. Significant correlations were found between the 5-year CSS and categorized number of TURBs (≤2 vs >2: 88% vs 71%; P= 0.001), interval between first TURB and rCx (≤4 months vs >4 months: 86% vs 77%; P= 0.04), adjuvant therapies (no vs yes: 86% vs 66%; P= 0.001), tumour upstaging at rCx (no vs yes: 89% vs 67%; P < 0.001), tumour stage at rCx (bladder confined vs non-confined: 88% vs 56%; P < 0.001) and LN status (no vs yes: 88% vs 36%; P < 0.001). •Multivariate analysis identified categorized number of TURBs (hazard ratio, HR, 0.14; 95% CI, 0.07-0.44; P < 0.001), categorized interval between first TURB and rCx (HR, 3.27; 95% CI, 1.24-8.59; P= 0.017), LN status (HR, 0.13; 95% CI, 0.06-0.26; P < 0.001) and tumour stage at rCx (HR, 0.49; 95% CI, 0.26-0.92; P= 0.03) as independent risk factors for CSS. CONCLUSION •Delay of rCx in 'high-risk' nmiBCA deteriorates CSS and should be avoided. The number of TURBs and the interval between first TURB and rCx are causative factors for delayed rCx and are independently correlated with CSS.

Abstract
INTRODUCTION There is a need for prognostic markers which can predict the subset of patients who will not respond sufficiently to conservative management in non-muscle-invasive bladder carcinoma. We analyzed the association of clusterin (CLU) with clinicopathological factors. MATERIALS AND METHODS Immunohistochemical CLU expression was investigated in paraffin-embedded archival tissues of initial transurethral resection specimens of 46 patients with non-muscle-invasive bladder carcinoma. The result was expressed as the proportion of the number of CLU-containing tumor cells to the total number of tumor cells detected in each slide and 'percent CLU expression' was calculated for each patient. RESULTS Of the 46 cases (35 male, 11 female), 18 were ≥ 65 years of age. CLU expression was significantly higher in male and elderly patients. Following the initial transurethral resection, 39 patients showed tumor recurrence, and progression was seen in 25 patients, of whom 17 progressed to muscle invasion during follow-up. Although there was no significant correlation between CLU expression and recurrence, significant correlation with overall progression and progression to muscle-invasive disease was observed in this cohort of patients (p = 0.001 and p = 0.014, respectively). Among the patients with progression to muscle invasion, 13 underwent radical cystectomy with pT2 tumor in 5 patients in the final pathology of surgical specimens and pT3 and higher in the remainder. CONCLUSIONS CLU immunoreactivity showed correlation with age, gender and progression, mainly progression to muscle invasion. Thus, CLU can be used as a molecular marker to predict the potential of progression to muscle-invasive disease in a particular tumor which in turn may prove useful in the decision-making process for early cystectomy without losing time with conservative management.

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
OBJECTIVE To ascertain which of the currently defined World Health Organization (WHO) grading classifications of pT1 urothelial bladder cancer (BC), published in 1973 and 2004, is more suitable for predicting outcome. PATIENTS AND METHODS Transurethral resection of the bladder (TURB) specimens of 310 patients with first diagnosis of initial pT1 BC were reassessed by three urological pathologists according to the WHO classifications of 1973 and 2004. The TURB procedure was followed by either immediate cystectomy or adjuvant bacille Calmette-Guérin (BCG) instillations. Kaplan-Meier analysis was used to compare survival rates of the different tumour grades (mean follow-up was 57 months). RESULTS According to the 1973 WHO classification, none of the pT1 BC specimens were graded as G1, while 36% were graded as G2 and 64% were graded as G3. Histological reassessment according to the 2004 WHO classification highlighted only 4% low-grade and 96% high-grade tumours. The 10-year cancer-specific survival rates of high-grade tumours (85%) were intermediate between G2 (96%) and G3 (78%). CONCLUSIONS The results of the present study support the presumption that the 1973 WHO classification is more suitable for predicting outcome for pT1 tumours, by defining at least two prognostic groups. A new classification should revise the definition of low- and high-grade pT1 BC to preserve the prognostic value of tumour grading.

Abstract
PURPOSE Bacillus Calmette-Guerin is the most effective therapy for nonmuscle invasive bladder cancer. Recently to calculate the risks of recurrence and progression based on data from 7 European Organisation for Research and Treatment of Cancer trials a scoring system was reported. However, in that series only 171 patients were treated with bacillus Calmette-Guerin. We developed a risk stratification model to provide accurate estimates of recurrence and progression probability after bacillus Calmette-Guerin. MATERIALS AND METHODS Data were analyzed on 1,062 patients treated with bacillus Calmette-Guerin and included in 4 Spanish Urological Club for Oncological Treatment trials. Stepwise multivariate Cox models were used to determine the effect of prognostic factors. In each patient the weight of all factors was summed to a total score. Patients were then divided into groups, and cumulative recurrence and progression rates were calculated. RESULTS A scoring system was calculated with a score of 0 to 16 for recurrence and 0 to 14 for progression. Patients were categorized into 4 groups by score, and recurrence and progression probabilities were calculated in each group. For recurrence the variables were gender, age, grade, tumor status, multiplicity and associated Tis. For progression the variables were age, grade, tumor status, T category, multiplicity and associated Tis. For recurrence calculated risks using Spanish Urological Club for Oncological Treatment tables were lower than those obtained with Sylvester tables. For progression probabilities were lower in our model only in patients with high risk tumors. CONCLUSIONS We propose a scoring model to stratify the risk of recurrence and progression in patients treated with bacillus Calmette-Guerin.

Abstract
OBJECTIVES Non-muscle invasive bladder cancer (NMIBC) classified as T1G3 represents one of the most challenging issues in urologic oncology. Although it is still considered a lesion amenable for conservative management, the risk for recurrence and progression remains high. The aim of this study was to define both recurrence and progression rate in patients with T1G3 UCC treated by complete transurethral resection (TURT) and adjuvant thermochemotherapy approach. MATERIALS AND METHODS We retrospectively evaluated the clinical data of patients with T1G3 NMIBC who underwent TURT followed by thermochemotherapy (TCT) treatment. Data recorded included age, gender, previous resections, previous intravesical treatment, time to tumor recurrence, and progression. TCT was given once weekly for 6 consecutive weeks, followed by 6 maintenance sessions at 4 to 6 weeks intervals. During each treatment session, 40 mg of mitomycin C (MMC) was instilled into the bladder in combination with bladder wall hyperthermia of 42 ± 2 °C for 60 minutes. Follow-up cystoscopy and urinary cytology were performed every 3 months for the first 2 years and than biannually. RESULTS A total of 56 T1G3 patients were treated with adjuvant TCT treatment at 7 urologic centers. Mean age was 68 years (range 35-91), 10 were females and 46 were males. Twenty-six patients failed on at least 1 previous intravesical treatment. Five patients who dropped out due to adverse events before reaching the first outcome evaluation cystoscopy were referred to another intravesical therapy, and were therefore excluded from the current analysis. A total 51 patients were available for analysis. Median follow-up time of tumor-free patients was 18 months (average 20, range 2-49 months). Seventeen patients (33.3%) had tumor recurrence and 4 of them progressed to muscle invasive disease. The median time to recurrence was 9 months (average 11, range 2-31 months). The Kaplan-Meier estimated recurrence rate for this group is: 42.9% at 2 years, 51.0% at 4 years. CONCLUSIONS TCT can be an effective adjuvant treatment option after TURT to prevent recurrence in patients with T1G3 NMIBC. Progression rate after this treatment was low (7.9%). TCT treatment was documented to be effective also in those who failed previous intravesical BCG. Treatment was confirmed to be safe and well tolerated.

Abstract
OBJECTIVE To study clinical and histopathologic parameters after cystectomy and lymphadenectomy in non-muscle-invasive transitional cell carcinoma (TCC) of the bladder and their association with the prevalence of lymph node metastases (N+). PATIENTS AND METHODS Of 866 patients treated with radical cystectomy and lymphadenectomy, 219 had non-muscle-invasive TCC of the bladder. The prevalence of N+ was related to parameters such as gender, age, number of transurethral resections of the bladder (TURBs), intervals between first TURB and cystectomy, adjuvant therapy, maximum histopathologic tumor stage and grade at TURB, and tumor upstaging in the cystectomy specimen by univariate and multivariate analysis. RESULTS A total of 33 patients (15%) had N+. By multivariate analyses, tumor upstaging and the number of TURBs were independent predictors of N+ at cystectomy. The number of TURBs increased the prevalence of N+ from 8% (one TURB) to 24% (two to four TURBs). Tumor upstaging in the cystectomy specimen increased the prevalence of N+ from 4% to 36%. CONCLUSION Inappropriate delay and staging errors of"high risk" non-muscle-invasive TCC of the bladder contribute to an increased prevalence of N+ and should be avoided. In our series, the number of TURBs and tumor upstaging in the cystectomy specimen were independent predictors for N+ by multivariate analysis.

Abstract
INTRODUCTION The management of transitional bladder cancer, which invades the lamina propria (pT1) and has a marked propensity for recurrence and progression, is controversial. Without adjuvant treatment the recurrence rate can be up to 80% and progression up to 50%. We retrospectively analyzed the incidence of recurrence and progression of pT1 transitional bladder cancer (grade 1-3) after complete transurethral resection of a bladder tumor (TURBT) and adjuvant immunotherapy with bacillus Calmette-Guérin (BCG). MATERIALS AND METHODS 77 patients with stage pT1 transitional cell carcinoma underwent TURBT of all visible tumors and adjuvant BCG intravesical instillations. Before BCG therapy, 12 patients presented with stage pT1 G1 tumors, 50 presented with pT1, and 15 with pT1 G3 tumors. RESULTS 51 patients (66.2%) were disease-free throughout the BCG instillation and follow-up period (median of 45 months); 8 patients (10.4%) experienced recurrence during the BCG instillations, but were disease-free following the last instillation; 16 patients (20.8%) experienced recurrence at a median of 17 months, and 2 patients (2.6%) with pT1 G3 died because of progression. CONCLUSIONS Adjuvant intravesical BCG therapy following TURBT appears to be an effective primary treatment for patients with pT1 transitional cell carcinoma.

Abstract
OBJECTIVES We compared long-term outcome in patients with initial pT1G3 bladder cancer (BC) treated with early versus deferred cystectomy (CX) for recurrent pT1G3 or muscle-invasive BC after an initial bladder-sparing approach. The aim of this study was to compare survival rates and to analyse the influence of the recognised risk factors multifocality, tumour size, and carcinoma in situ (CIS) in initial transurethral resection of the bladder. METHODS Between 1995 and 2005, a total of 105 patients were diagnosed with initial pT1G3 BC featuring>or=2 risk factors. Forty-five percent had multiple tumours, 73% tumours>3 cm in size, and 46% CIS. All patients were offered early CX. Fifty-one percent of patients opted for early and 49% underwent deferred CX for recurring BC. Risk factors were distributed evenly between the groups. RESULTS Upstaging in the CX specimen was found in 30% of cases. No risk factor was related to upstaging. The 10-yr cancer-specific survival rate was 78% in early CX and 51% in deferred CX (p<0.01). No risk factor predicted cancer-related death in early CX. In survival analysis, CIS was related to a lower cancer-specific survival rate in deferred CX (p<0.001). CONCLUSIONS Early as opposed to deferred CX seems to prolong the cancer-specific survival rate in high-risk pT1G3 BC. Patients with CIS should be considered for early CX owing to reduced cancer-specific survival in case of deferred CX.

Abstract
Management decisions for a patient with high grade (G3) T1 urothelial cancer of the bladder are critical. These tumors should not be classified as "superficial" since they are not confined to the urothelium. Patients with T1G3 bladder cancers are likely to have recurrence and the tumor will often progress, invade, metastasize, and cause death. Radical cystectomy as well as transurethral resection followed by intravesical BCG are acceptable initial therapies. This article reviews these treatment options and provides recommendations for management of high grade T1 tumors.

Abstract
PURPOSE Historically patients with recurrent T1 bladder tumors after bacillus Calmette-Guerin have been treated with bladder sparing approaches. Recently a paradigm shift has occurred since patients are increasingly offered radical cystectomy before disease progression to muscle invasion. In this study we explored the effect of this paradigm shift on progression rates and disease specific survival. MATERIALS AND METHODS The historical cohort consisted of 307 patients from 3 prospective intravesical bacillus Calmette-Guerin protocols from 1980 to 1989. An institutional review board approved review identified 589 patients treated with bacillus Calmette-Guerin in a contemporary cohort from 1992 to 2004. RESULTS In the historical cohort the 85 patients with documented T1 recurrence were initially treated with repeat transurethral resection and intravesical bacillus Calmette-Guerin. Of these 85 patients 60 had progression to muscle invasive disease. At 5 years after T1 recurrence, the cumulative incidence of progression to T2 disease was 71% (95% CI 61%, 81%) and the cumulative incidence of death from disease was 48% (95% CI 39%, 60%). In the contemporary cohort 129 patients had documented T1 recurrence. In this cohort 65 of the 129 patients with recurrent T1 underwent immediate radical cystectomy. At 5 years after T1 recurrence, the cumulative incidence of progression to muscle invasive disease was 28% (95% CI 20%, 38%) and the cumulative incidence of death from disease was 31% (95% CI 22%, 42%). CONCLUSIONS Preemptive radical cystectomy performed for recurrent T1 disease following intravesical bacillus Calmette-Guerin therapy may be associated with better disease specific survival.

Abstract
OBJECTIVES To report the long-term outcome of patients with Stage T1 high-grade transitional cell carcinoma of the bladder treated initially by transurethral resection and adjuvant intravesical bacille Calmette-Guérin. METHODS From June 1984 to November 1995, 78 consecutive patients with Stage T1 high-grade bladder cancer underwent transurethral resection and adjuvant intravesical bacille Calmette-Guérin therapy. The results at the interim follow-up (median 56 months) were reported in 1998. The median duration of follow-up for the present study was 107 months (range 16 to 238). The endpoints were tumor recurrence (Stage Ta, T1, or Tis), tumor progression (to T2 or greater), and disease-specific survival. RESULTS Of the 78 patients, 34 (44%) were alive for the present analysis and 44 (56%) had died, 12 (16%) of transitional cell carcinoma and 32 (72%) of other causes. Recurrence was documented in 27 patients (35%) at a median of 8.5 months (range 5 to 129) after treatment, and progression in 14 patients (18%) at a median of 31.4 months (range 5 to 88) after treatment. The 2, 5, and 10-year recurrence-free survival and progression-free survival rates were 76%, 72%, and 62% and 92%, 82%, and 80%, respectively. The corresponding disease-free survival rates were 99%, 90%, and 85%. Disease progression occurred in 10 (37%) of 27 patients with recurrence, of whom 9 died. Of the 14 patients with disease progression, 12 died of their disease. CONCLUSIONS Bacille Calmette-Guérin is an effective conservative treatment for patients with Stage T1 high-grade bladder cancer. More than one half the recurrences appeared within the first year, but a small risk remains throughout the patient's life. Progression during follow-up appears to carry a high risk of cancer-specific death.

Abstract
PURPOSE On a routine basis we performed systematic molecular screening for FGFR3 and TP53 mutations in 121 bladder tumors. We then specifically analyzed the predictive value of the recurrence of FGFR3 and TP53 genotypes in superficial lesions. MATERIALS AND METHODS The FGFR3 gene was analyzed by direct sequencing of exons 7, 10 and 15, whereas TP53 status was determined using the p53 functional assay in yeast. RESULTS We identified a missense FGFR3 mutation in 66% of pTa, 26% of pT1 and 12% of pT2 tumors. Of activating FGFR3 mutations 54% and 85% were found in low G1 and intermediate G2 grade tumors, respectively, but in only 20% of high grade G3 tumors. We detected inactivating TP53 mutations in 10% of pTa, 42% of pT1 and 58% of pT2 tumors. Moreover, TP53 mutations were found only in 23% of grade G1 and 3% of grade G2 tumors but in 44% of high grade G3 tumors. When the 2 genotypes were combined, we observed that 58% of pTa tumors had the (mutant FGFR3, WT TP53) genotype, whereas 58% of invasive lesions harbored the inverse genotype (WT FGFR3, mutant TP53). The (mutant FGFR3, WT TP53) genotype and the (WT FGFR3, mutant TP53) genotype were detected in 23% and 38% of pT1G3 tumors, respectively. In the subgroup of 92 patients with superficial pTa-T1 bladder tumors we did not find that the TP53 or FGFR3 genotype alone or combined had a predictive value for tumor recurrence. CONCLUSIONS Our data again represent solid proof for the pivotal role of FGFR3 and TP53 mutations in superficial and invasive bladder tumors, respectively. However, other molecular markers should be identified for borderline pT1G3 bladder tumors, which are probably at the crossroads of these 2 distinct molecular pathways.

Abstract
PURPOSE We evaluated the potential benefit of a second transurethral resection in patients with newly diagnosed pT1 transitional cell carcinoma of the bladder. MATERIALS AND METHODS Between January 2001 and May 2003, 80 patients with stage T1 bladder cancer were included in this protocol in which all patients prospectively received second TUR within 2 to 6 weeks following the initial resection. Patients with incomplete resections were excluded from study. The pathological findings of the second TUR were reviewed. RESULTS Of the 80 patients who underwent second resection, 18 (22.5%) had macroscopic tumors before resection. However, with the addition of microscopic tumors, overall residual disease was determined in 27 (33.8%) patients. Of the 27 patients 7 had pTa, 14 had pT1, 3 had pT1+pTis and 3 had pT2 disease. Residual cancers were detected in 5.8%, 38.2% and 62.5% in G1, G2 and G3 tumors, respectively. The risk of residual tumor directly correlated with the grade of the initial tumor (p = 0.009). CONCLUSIONS Although second TUR dramatically changed the treatment strategy in a small percentage of cases, we strongly recommend performing second TUR in all cases of primary pT1 disease, especially in high grade cases.

Abstract
The International Consensus Panel on T1 bladder tumors markers reviewed the subject from a clinical perspective. From diagnosis to treatment decisions, what are the important issues in the management of a new patient? The assessment of prognostic factors for progression requires optimal resection and documentation. The role of immediate adjuvant intravesical chemotherapy after resection remains controversial. How often should the upper tract be assessed for tumor recurrence? The decision on whether to attempt bladder conservation with intravesical therapy or to perform a cystectomy is the most difficult issue in the management of superficial bladder cancer today. Finally, what therapies exist if initial intravesical bacille Calmette-Guérin fails to eradicate the disease or prevent recurrence? The panel thoroughly explored all these subjects and has made recommendations with supporting evidence.

Abstract
People with pT1 G3 bladder cancer are at high risk of tumour progression and death. Induction and maintenance intravesical Bacillus Calmette-Guerin (BCG) has been proven to reduce tumour progression in superficial bladder cancer at moderate risk of progression. By extrapolation, this treatment is often now given for pT1 G3 bladder cancer. Phase II studies published over the past 10 years on the use of adjuvant intravesical BCG following transurethral resection (TUR) of the tumour(s) suggest an important effect on the number of patients progressing. The data are mixed, however. A randomised study of the use of adjuvant radiotherapy in pT1 G3 bladder cancer has shown that it is not of benefit and that, overall, the progression rate remains high. Early cystectomy for high-risk cases is not commonly used, and its results are often disappointing, presumably a consequence of negative selection. Identification of patients at extra high risk of progression is desirable. Tumour size, the co-existence of carcinoma in situ and early tumour recurrence may be prognostic indicators, but the data are at present insufficient.

Abstract
TIG3 transitional cell carcinoma of the bladder represents a highly malignant tumor with a variable and unpredictable biologic potential. The most critical aspect of management requires a detailed discussion with the patient regarding the treatment options. Both the physician and the patient should be willing to reconsider the treatment options as the disease continues to evolve. In most cases initial management involves complete resection of the tumor, accurate staging of the disease, and intravesical immunotherapy or chemotherapy. Rigorous surveillance with long-term follow-up is crucial for managing these cases. In selected cases with adverse prognostic factors immediate cystectomy should be considered. The choice and timing of the decision to abandon bladder preservation and proceed with cystectomy should be continuously reconsidered on an individual patient basis, in concordance with the evolution of the disease (Fig. 1). The goal is to spare the bladder when possible but not at the risk of death from metastatic disease. Radical cystectomy in high-grade stage T1 transitional cell carcinoma offers excellent results in regard to the prevention of recurrence and progression and survival. Improvements in urinary diversion and nerve-sparing techniques have decreased the magnitude of social implications related to cystectomy in most patients regardless of gender. The discovery of reliable markers may contribute to better selection of patients for bladder sparing. Until then, the optimal treatment for the T1G3 tumor remains controversial.

Abstract
PURPOSE To our knowledge this is the first report of intravesical oncolytic reovirus for therapy of superficial bladder cancer in an orthotopic bladder tumor model. Superficial bladder carcinomas are often multifocal and have high recurrences after surgical resection. In 20% of cases intravesical immunotherapy fails to prevent recurrence and complications from bacillus Calmette-Guerin (BCG) are common. Human reovirus is an oncolytic virus that selectively destroys cancer cells with an activated Ras pathway. We examined the ability of this virus to kill bladder cancer cells in vitro and inhibit tumor growth in vivo. MATERIALS AND METHODS Following cytotoxicity assays in vitro dose escalation of intravesical reovirus was tested for tumor control and toxicity in a rat model. Treatments were done twice weekly for 3 weeks. In parallel intravesical BCG was studied. Animals were monitored on a daily basis for health status and by routine urine cytology. Animals underwent necropsy at study end point and appropriate tissues were taken for histology. RESULTS Side effects in reovirus groups were minor compared with BCG complications. Tumor response (animal survival) was 90% 100 days after tumor implantation in reovirus treated animals, whereas the highest survival in BCG treated groups was 50%. Animals treated with reovirus had significantly higher tumor-free survival than those treated with immunotherapy or normal saline (log rank test p = 0.0002 and 0.04, respectively). CONCLUSIONS Intravesical reovirus is safe and effective in this animal model and it may have clinical applications for bladder cancer treatment.
