Abstract
OBJECTIVES Multiple clinical practice guidelines, conflicting evidence, and physician perceptions result in variations in risk stratification among patients with non-muscle-invasive bladder cancer (NMIBC). This study aims to describe the extent of this variation and its impact on management approaches in the Asia-Pacific region. METHODS We conducted a cross-sectional survey involving 32 urologists and seven medical oncologists with ≥8 years of experience managing early-stage bladder cancer patients across Australia, Hong Kong, Japan, South Korea, Singapore, and Taiwan. The physicians completed an anonymous questionnaire that assessed their risk stratification and respective management approaches, based on 19 NMIBC characteristics. For each NMIBC characteristic, they were required to select one risk group, and their most preferred management approach. RESULTS Our results demonstrated a higher consensus on risk classification versus management approaches. More than 50% of the respondents agreed on the risk classification of all NMIBC characteristics, but 42% or fewer chose the same treatment option as their preferred choice for all but two characteristics-existence of variant histology (55%) and persistent high-grade T1 disease on repeat resection (52%). Across territories, there was the greatest variation in preferred treatment options (i.e., no treatment, intravesical chemotherapy, or Bacillus Calmette-Guérin [BCG] treatment) for intermediate-risk patients and the highest consensus on the treatment of very high-risk patients, namely radical cystectomy. CONCLUSIONS Our study revealed considerable variation in risk stratification and management of NMIBC in the region. It is critical to develop practical algorithms to facilitate the recognition of NMIBC and standardize the treatment of NMIBC patients.

Abstract
OBJECTIVES Clinical guidelines recommend that patients with non-muscle-invasive bladder cancer (NMIBC) should be treated with appropriate adjuvant therapy. However, compliance with guideline recommendations is insufficient, and this may lead to unfavorable outcomes. We aimed to investigate the level of adherence to guideline recommendations in patients with NMIBC and evaluate the outcomes of those who did and did not receive guideline-recommended therapies. METHODS We performed a retrospective analysis of patients with histologically diagnosed NMIBC. The percentage of patients with intermediate- and high-risk tumors who received adjuvant intravesical therapy or second transurethral resection (TUR) was calculated. Recurrence-free survival was assessed in patients who did and did not receive the therapies. We conducted a propensity score-matched analysis to compare outcomes between patients with intermediate-risk and T1 NMIBC who did and did not undergo guideline-recommended therapies. RESULTS Overall, 1204 patients from the Tohoku Urological Evidence-Based Medicine Study Group and Kyoto University Hospital were included. Of patients with intermediate- and high-risk tumors, 91.0% and 74.0% did not receive maintenance bacillus Calmette-Guérin (BCG), respectively. In both groups, significantly better recurrence-free survival was found for patients treated with maintenance BCG. Among patients with T1 NMIBC, only 16.7% underwent guideline-recommended therapies, that is, a second TUR and maintenance BCG. Significantly greater recurrence-free survival was observed in patients who received guideline-recommended therapies compared with propensity-matched patients who did not. CONCLUSIONS Guideline-recommended therapies may contribute to improvements in outcomes for patients with NMIBC, suggesting that improvements in adherence to clinical guidelines may lead to favorable outcomes.

Abstract
OBJECTIVE Among patients diagnosed with non-muscle invasive bladder cancer (NMIBC), those with high risk disease have the greatest risk of recurrence and disease progression. The underutilization of intravesical immunotherapy with Bacillus Calmette-Guérin (BCG) has been a longstanding concern in clinical practice. This study aimed to determine the disparities present in receipt of adjuvant intravesical chemotherapy and immunotherapy in treatment of patients with high grade NMIBC following initial transurethral resection of a bladder tumor (TURBT). METHODS The California Cancer Registry data was used to identify 19,237 patients diagnosed with high grade NMIBC who underwent TURBT. Treatment variables include re-TURBT, re-TURBT and intravesical chemotherapy (IVC) and/or BCG. Independent variables include age, sex, race/ethnicity, neighborhood socioeconomic status (nSES), primary insurance payer and marital status at diagnosis. Multiple logistic regression and multinomial regression models were used to examine variation in the treatments received following TURBT. RESULTS The proportion of patients receiving TURBT followed by BCG was similar across all racial and ethnic groups (28%-32%). BCG therapy was higher in patients belonging to the highest nSES quintile (37% for highest vs. 23%-26% for the 2 lowest quintiles). In multiple variable analyses, receipt of any intravesical therapy (IVT) was influenced by nSES, age, marital status, race/ethnicity, and insurance type. Patients in the lowest nSES quintile had a 45% less likelihood of receiving IVT compared to the highest nSES group (OR [95%CI]: 0.55[0.49, 0.61]). Race/ethnicity differences in receipt of any adjuvant therapy were noted in the middle to lowest nSES quintile for Hispanic and Asian/Pacific Islander patients when compared to non-Hispanic White patients. When comparing variation in treatment by insurance type at diagnosis, those with Medicare or other insurance were 24% and 30% less likely to receive BCG after TURBT compared to those with private insurance, (OR [95%CI]: 0.76 [0.70, 0.82] and 0.70[0.62, 0.79]) respectively. CONCLUSION In patients with a diagnosis of high risk NMIBC, disparities in utilization of BCG are seen based on SES, age, and insurance type.

Abstract
Intravesical immunotherapy with Bacillus Calmette-Guérin (BCG) has been the standard of care for patients with high-risk non non-muscle invasive bladder cancer (NMIBC) for over four decades. Despite its success as a cancer immunotherapy, disease recurrence and progression remain common. Current efforts are focused on developing effective and well-tolerated alternatives to BCG and salvage bladder preservation therapies after BCG has failed. The focus of this review is to synthesize our current understanding of the molecular biology and tumor immune microenvironment of NMIBC to provide rationale for existing and emerging therapeutic targets. We highlight recent and ongoing clinical trials and define the current treatment landscape, challenges, and future directions of salvage treatment. Combination regimens that are rationally designed will be needed to make meaningful therapeutic advancements. Investigations into the molecular underpinnings of NMIBC are leading to the emergence of predictive molecular biomarkers that provide greater insight into the clinical heterogeneity of NMIBC and enable us to identify drivers of treatment resistance and new therapeutic targets.

Healthcare Resource Utilization and Cost Burden of BCG-Treated Non-Muscle Invasive Bladder Cancer Patients in Germany: A Retrospective Claims Analysis. CLINICOECONOMICS AND OUTCOMES RESEARCH 2023; 15:227-237.

Abstract
Background Intermediate and high-risk non-muscle-invasive bladder cancer (NMIBC) is typically managed with transurethral resection of the bladder tumour (TURBT) followed by intravesical Bacillus Calmette-Guérin (BCG) immunotherapy; however, NMIBC patients can become refractory or unresponsive to BCG treatment, and/or progress to muscle-invasive bladder cancer (MIBC). Healthcare resource utilization (HCRU) and costs in these patient populations are high. Methods A retrospective longitudinal cohort design of adult (≥18 years) patients with bladder cancer and BCG treatment (01/01/2012-31/12/2017) was conducted using data from a representative subset of the German statutory health insurance database. During the follow-up period after last BCG, patients were categorized into subgroups of No further NMIBC treatment, Continuous treatment for NMIBC, or MIBC evidence; HCRU and costs were tabulated for each subgroup and for the entire cohort. Results A total of 1049 patients met the study inclusion criteria (mean age, 70.9 years; 84.8% male). Across the different subgroups, patients showing MIBC evidence had more than two times higher hospitalization rates compared to the other subgroups. Overall, the entire BCG-treated cohort's total direct medical cost including hospitalizations, outpatient care and drugs was €33.9 million and €9250 per patient-year. Cost for patients with MIBC evidence was much higher, at €17,983 per patient-year, than patients with No further NMIBC treatment (€6617) and patients with Continuous treatment for NMIBC (€7786). Across the subgroups, hospitalization was the largest driver of cost and contributed the most to cost for those with MIBC evidence. Conclusion The overall cost burden of this BCG-treated cohort of 1049 patients is high (€38 million whereof 4.1 million are indirect costs) over a mean follow-up of 3.9 years; economic burden is especially substantial for patients who fail BCG treatment and those who progress.

Hyperthermic Mitomycin C in Intermediate-risk Non-muscle-invasive Bladder Cancer: Results of the HIVEC-1 Trial. Eur Urol Oncol 2023; 6:58-66. [PMID: 36435738 DOI: 10.1016/j.euo.2022.10.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2022] [Revised: 09/29/2022] [Accepted: 10/31/2022] [Indexed: 11/25/2022]
Abstract
BACKGROUND Optimising therapeutic strategies of intermediate-risk non-muscle-invasive bladder cancer (IR-NMIBC) is needed. OBJECTIVE To compare recurrence-free survival (RFS) with adjuvant intravesical mitomycin C (MMC) at normothermia or hyperthermia using the COMBAT bladder recirculation system at 43 °C for 30 and 60 min. DESIGN, SETTING, AND PARTICIPANTS A prospective open-label, phase 3 randomised controlled trial (HIVEC-1) accrued across 13 centres between 2014 and 2020 in Spain. After complete transurethral resection of the bladder and immediate postoperative MMC instillation, patients with IR-NMIBC were randomised (1:1:1) to four weekly followed by three monthly 40-mg MMC instillations at normothermia (control; n = 106), 43 °C for 30 min (n = 107), or 43 °C for 60 min (n = 106) were investigated. Therapeutic compliance was defined as four or more instillations. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The primary outcome was RFS at 24 mo in the intention-to-treat (ITT) and per-protocol (PP) populations. The secondary outcomes included progression-free survival at 24 mo, safety outcome measures, and changes in health-related quality of life. Log-rank, Fisher, χ2, and analysis of variance tests were used. RESULTS AND LIMITATIONS The ITT 24-mo RFS was 77% for control, 82% for 43 °C-30 min, and 80% for 43 °C-60 min (p = 0.6). The PP 24-mo RFS was 77% for control, 83% for 43 °C-30 min, and 80% for 43 °C-60 min (p = 0.59). Six patients progressed to muscle-invasive disease in the ITT population (four in the control, 43 °C-30 min, and 43 °C-60 min groups each) and four in the PP population (all controls). Serious adverse events occurred in 26 patients (8.1%), and we were unable to demonstrate a difference between groups (p = 0.5). Adverse events, mainly dysuria and spasms, occurred in 124 patients (33% in control, 35% in 43 °C-30 min, and 48% in 43 °C-60 min; p = 0.05). The total International Prostate Symptom Score worsened by 1.2 ± 7.3 points, similarly across groups (p = 0.29). The Functional Assessment of Cancer Therapy-Bladder domains and indexes showed no significant change. CONCLUSIONS Four-month adjuvant hyperthermic MMC using the COMBAT system for 30 and 60 min in IR-NMIBC is well tolerated, but we did not find it to be superior to normothermic MMC at 24 mo. PATIENT SUMMARY We were unable to demonstrate the effectiveness of hyperthermia using the COMBAT system in intermediate-risk non-muscle-invasive bladder cancer. Further evaluation of long-term recurrence and progression, and maintenance regimens appears mandatory.

Urinary Eubacterium sp. CAG:581 Promotes Non-Muscle Invasive Bladder Cancer (NMIBC) Development through the ECM1/MMP9 Pathway. Cancers (Basel) 2023; 15:cancers15030809.

Abstract
BACKGROUND Increasing evidence points to the urinary microbiota as a possible key susceptibility factor for early-stage bladder cancer (BCa) progression. However, the interpretation of its underlying mechanism is often insufficient, given that various environmental conditions have affected the composition of urinary microbiota. Herein, we sought to rule out confounding factors and clarify how urinary Eubacterium sp. CAG:581 promoted non-muscle invasive bladder cancer (NMIBC) development. METHODS Differentially abundant urinary microbiota of 51 NMIBC patients and 47 healthy controls (as Cohort 1) were first determined by metagenomics analysis. Then, we modeled the coculture of NMIBC organoids with candidate urinary Eubacterium sp. CAG:581 in anaerobic conditions and explored differentially expressed genes of these NMIBC tissues by RNA-Seq. Furthermore, we dissected the mechanisms involved into Eubacterium sp. CAG:581 by inducing extracellular matrix protein 1 (ECM1) and matrix metalloproteinase 9 (MMP9) upregulation. Finally, we used multivariate Cox modeling to investigate the clinical relevance of urinary Eubacterium sp. CAG:581 16S ribosomal RNA (16SrRNA) levels to the prognosis of 406 NMIBC patients (as Cohort 2). RESULTS Eubacterium sp. CAG:581 infection accelerated the proliferation of NMIBC organoids (p < 0.01); ECM1 and MMP9 were the most upregulated genes induced by the increased colony forming units (CFU) gradient of Eubacterium sp. CAG:581 infection via phosphorylating ERK1/2 in NMIBC organoids of Cohort 1. Excluding the favorable impact of potential contributing factors, the ROC curve of Cohort 2 manifested its 3-year AUC value as 0.79 and the cut-off point of Eubacterium sp. CAG:581 16SrRNA as 10.3 (delta CT value). CONCLUSION Our evidence suggests that urinary Eubacterium sp. CAG:581 promoted NMIBC progression through the ECM1/MMP9 pathway, which may serve as the promising noninvasive diagnostic biomarker for NMIBC.

Mapping European Association of Urology Guideline Practice Across Europe: An Audit of Androgen Deprivation Therapy Use Before Prostate Cancer Surgery in 6598 Cases in 187 Hospitals Across 31 European Countries. Eur Urol 2023; 83:393-401. [PMID: 36639296 DOI: 10.1016/j.eururo.2022.12.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Revised: 11/30/2022] [Accepted: 12/26/2022] [Indexed: 01/13/2023]
Abstract
BACKGROUND Evidence-practice gaps exist in urology. We previously surveyed European Association of Urology (EAU) guidelines for strong recommendations underpinned by high-certainty evidence that impact patient experience for which practice variations were suspected. The recommendation "Do not offer neoadjuvant androgen deprivation therapy (ADT) before surgery for patients with prostate cancer" was prioritised for further investigation. ADT before surgery is neither clinically effective nor cost effective and has serious side effects. The first step in improving implementation problems is to understand their extent. A clear picture of practice regarding ADT before surgery across Europe is not available. OBJECTIVE To assess current ADT use before prostate cancer surgery in Europe. DESIGN, SETTING, AND PARTICIPANTS This was an observational cross-sectional study. We retrospectively audited recent ADT practices in a multicentre international setting. We used nonprobability purposive sampling, aiming for breadth in terms of low- versus high-volume, academic, versus community and public versus private centres. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Our primary outcome was adherence to the ADT recommendation. Descriptive statistics and a multilevel model were used to investigate differences between countries across different factors (volume, centre type, and funding type). Subgroup analyses were performed for patients with low, intermediate, and high risk, and for those with locally advanced prostate cancer. We also collected reasons for nonadherence. RESULTS AND LIMITATIONS We included 6598 patients with prostate cancer from 187 hospitals in 31 countries from January 1, 2017 to May 1, 2020. Overall, nonadherence was 2%, (range 0-32%). Most of the variability was found in the high-risk subgroup, for which nonadherence was 4% (range 0-43%). Reasons for nonadherence included attempts to improve oncological outcomes or preoperative tumour parameters; attempts to control the cancer because of long waiting lists; and patient preference (changing one's mind from radiotherapy to surgery after neoadjuvant ADT had commenced or feeling that the side effects were intolerable). Although we purposively sampled for variety within countries (public/private, academic/community, high/low-volume), a selection bias toward centres with awareness of guidelines is possible, so adherence rates may be overestimated. CONCLUSIONS EAU guidelines recommend against ADT use before prostate cancer surgery, yet some guideline-discordant ADT use remains at the cost of patient experience and an additional payer and provider burden. Strategies towards discontinuation of inappropriate preoperative ADT use should be pursued. PATIENT SUMMARY Androgen deprivation therapy (ADT) is sometimes used in men with prostate cancer who will not benefit from it. ADT causes side effects such as weight gain and emotional changes and increases the risk of cardiovascular disease, diabetes, and osteoporosis. Guidelines strongly recommend that men opting for surgery should not receive ADT, but it is unclear how well the guidance is followed. We asked urologists across Europe how patients in their institutions were treated over the past few years. Most do not use ADT before surgery, but this still happens in some places. More research is needed to help doctors to stop using ADT in patients who will not benefit from it.

BACKGROUND Around 7500 people are diagnosed with non-muscle-invasive bladder cancer in the UK annually. Recurrence following transurethral resection of bladder tumour is common, and the intensive monitoring schedule required after initial treatment has associated costs for patients and the NHS. In photodynamic diagnosis, before transurethral resection of bladder tumour, a photosensitiser that is preferentially absorbed by tumour cells is instilled intravesically. Transurethral resection of bladder tumour is then conducted under blue light, causing the photosensitiser to fluoresce. Photodynamic diagnosis-guided transurethral resection of bladder tumour offers better diagnostic accuracy than standard white-light-guided transurethral resection of bladder tumour, potentially reducing the chance of subsequent recurrence. OBJECTIVE The objective was to assess the clinical effectiveness and cost-effectiveness of photodynamic diagnosis-guided transurethral resection of bladder tumour. DESIGN This was a multicentre, pragmatic, open-label, parallel-group, non-masked, superiority randomised controlled trial. Allocation was by remote web-based service, using a 1 : 1 ratio and a minimisation algorithm balanced by centre and sex. SETTING The setting was 22 NHS hospitals. PARTICIPANTS Patients aged ≥ 16 years with a suspected first diagnosis of high-risk non-muscle-invasive bladder cancer, no contraindications to photodynamic diagnosis and written informed consent were eligible. INTERVENTIONS Photodynamic diagnosis-guided transurethral resection of bladder tumour and standard white-light cystoscopy transurethral resection of bladder tumour. MAIN OUTCOME MEASURES The primary clinical outcome measure was the time to recurrence from the date of randomisation to the date of pathologically proven first recurrence (or intercurrent bladder cancer death). The primary health economic outcome was the incremental cost per quality-adjusted life-year gained at 3 years. RESULTS We enrolled 538 participants from 22 UK hospitals between 11 November 2014 and 6 February 2018. Of these, 269 were allocated to photodynamic diagnosis and 269 were allocated to white light. A total of 112 participants were excluded from the analysis because of ineligibility (n = 5), lack of non-muscle-invasive bladder cancer diagnosis following transurethral resection of bladder tumour (n = 89) or early cystectomy (n = 18). In total, 209 photodynamic diagnosis and 217 white-light participants were included in the clinical end-point analysis population. All randomised participants were included in the cost-effectiveness analysis. Over a median follow-up period of 21 months for the photodynamic diagnosis group and 22 months for the white-light group, there were 86 recurrences (3-year recurrence-free survival rate 57.8%, 95% confidence interval 50.7% to 64.2%) in the photodynamic diagnosis group and 84 recurrences (3-year recurrence-free survival rate 61.6%, 95% confidence interval 54.7% to 67.8%) in the white-light group (hazard ratio 0.94, 95% confidence interval 0.69 to 1.28; p = 0.70). Adverse event frequency was low and similar in both groups [12 (5.7%) in the photodynamic diagnosis group vs. 12 (5.5%) in the white-light group]. At 3 years, the total cost was £12,881 for photodynamic diagnosis-guided transurethral resection of bladder tumour and £12,005 for white light. There was no evidence of differences in the use of health services or total cost at 3 years. At 3 years, the quality-adjusted life-years gain was 2.094 in the photodynamic diagnosis transurethral resection of bladder tumour group and 2.087 in the white light group. The probability that photodynamic diagnosis-guided transurethral resection of bladder tumour was cost-effective was never > 30% over the range of society's cost-effectiveness thresholds. LIMITATIONS Fewer patients than anticipated were correctly diagnosed with intermediate- to high-risk non-muscle-invasive bladder cancer before transurethral resection of bladder tumour and the ratio of intermediate- to high-risk non-muscle-invasive bladder cancer was higher than expected, reducing the number of observed recurrences and the statistical power. CONCLUSIONS Photodynamic diagnosis-guided transurethral resection of bladder tumour did not reduce recurrences, nor was it likely to be cost-effective compared with white light at 3 years. Photodynamic diagnosis-guided transurethral resection of bladder tumour is not supported in the management of primary intermediate- to high-risk non-muscle-invasive bladder cancer. FUTURE WORK Further work should include the modelling of appropriate surveillance schedules and exploring predictive and prognostic biomarkers.

Abstract
Bacillus Calmette–Guérin (BCG) is the gold standard adjuvant treatment for non-muscle-invasive bladder cancer (NMIBC). However, given the current global shortage of BCG, new treatments are needed. We evaluated tumor microenvironment markers as potential BCG alternatives for NMIBC treatment. Programmed death-ligand 1, human epidermal growth factor receptor-2 (HER2), programmed cell death-1 (PD1), CD8, and Ki67 levels were measured in treatment-naïve NMIBC and MIBC patients (pTa, pT1, and pT2 stages). Univariate and multivariate Cox proportional hazard models were used to determine the impact of these markers and other clinicopathological factors on survival, recurrence, and progression. EP263, IM142, PD1, and Ki67 levels were the highest in the T2 stage, followed by the T1 and Ta stages. HER2 and IM263 expressions were higher in the T1 and T2 stages than in the Ta stage. In NMIBC, the significant prognostic factors for recurrence-free survival were adjuvant therapy, tumor grade, and HER2 positivity, whereas those for progression-free survival included age, T-stage, and IM263. Age, T-stage, EP263, PD1, CD8, and Ki67 levels were significant factors associated with overall survival. IM263 and HER2 are potential biomarkers for progression and recurrence, respectively. Therefore, we propose HER2 as a potential target antigen for intravesical therapeutics as a BCG alternative.

Abstract
OBJECTIVES To evaluate overall and recurrence-progression rate-adjusted concordance of treatment prescription in non-muscle-invasive bladder cancer (NMIBC) of an app based on the best available scientific evidence and the urologist's opinion. METHODS Development of an app (APPv) specifically designed for the treatment and follow-up of NMIBC and validation of the proposed APPv treatment endpoint by means of a prospective double-blind observational concordance study of related samples in 100 patients with initial or successive histological diagnosis of NMIBC. RESULTS The treatment prescribed by the urologist agrees with that proposed by the APPv in 64% of cases (kappa index 0.55, P < 0.0001). Regarding low risk, the agreement is 77% (kappa 0.55, P = 0.002), 63% (kappa 0.52, P < 0.0001) for intermediate risk, 17% (kappa 0.143, P = 0.014) in high risk and 66% (kappa 0.71, P = 0.01) for very high risk. Of patients receiving adjuvant intravesical treatment according to APPv, 89.1% remain free of recurrence vs. 61.1% of those with disagreement (P = 0.0004), with a RR 0.46 (95%CI: 0.25-0.86) vs. RR 2.4 (95%CI: 1.5-3.8, P = 0.001). In the APPv-urologist agreement group, 100% of patients are free of progression and 88.9% in the disagreement group (P = 0.004) with a RR 1 vs. RR 1.125 (95%CI: 1-1.26, P = 0.004). CONCLUSIONS APPv can improve adherence to treatment recommendations according to clinical practice guidelines and health outcomes at NMIBC.

Abstract
Background Non-muscle-invasive bladder cancer (NMIBC) still poses a heavy load for resulting in many new cases which contribute significantly to medical costs. Although many NMIBC guidelines have been developed, their implementation remains deficient. Objective This study was conducted in order to analyze the knowledge of and compliance with the guidelines for NMIBC of Chinese urologists and to identify associated factors. Methods We conducted an online survey between August 2019 and January 2021. Respondents who were more than 65 years old or did not give informed consent were excluded. Linear/logistic regressions were performed to identify factors associated with the knowledge of and compliance with the guidelines of urologists, respectively. McNemar's tests were used to explore the divergence between knowledge and compliance. Results A total of 814 responses were received, and 98.77% of urologists acknowledged the positive effects of high-quality guidelines. The average knowledge score was 6.10 ± 1.28 (out of a full score of 9), and it was positively associated with educational level and the number of guidelines consulted. Only 1.61% and 39.36% of the respondents realized that the guidelines did not recommend further chemotherapy or BCG infusion for low-risk patients. There were 38.87% and 51.84% respondents "often" or more frequently utilizing BCG therapy for intermediate- and high-risk NMIBC patients, respectively. Divergence between knowledge and compliance in performing a second TURBT after incomplete initial resection reached statistical significance (p < 0.001). Conclusions Although the vast majority of urologists acknowledged the positive effects of guidelines, knowledge of and compliance with some recommendations of NMIBC guidelines are still inadequate. Factors associated with guidelines, individual professionals, patients, organizations, and the environment jointly contributed to the non-compliance.

Long-Term Experience with Hyperthermic Chemotherapy (HIVEC) Using Mitomycin-C in Patients with Non-Muscle Invasive Bladder Cancer in Spain. J Clin Med 2021; 10:jcm10215105.

Abstract
(1) Background: Intravesical mitomycin-C (MMC) combined with hyperthermia is increasingly used in non-muscle invasive bladder cancer (NMIBC), especially in the context of a relative BCG shortage. We aim to determine real-world data on the long-term treatment outcomes of adjunct hyperthermic intravesical chemotherapy (HIVEC) with MMC and a COMBAT® bladder recirculation system (BRS); (2) Methods: A prospective observational trial was performed on patients with NMIBC treated with HIVEC using BRS in nine academic institutions in Spain between 2012–2020 (HIVEC-E). Treatment effectiveness (recurrence, progression and overall mortality) was evaluated in patients treated with HIVEC MMC 40mg in the adjuvant setting, with baseline data and a clinical follow-up, that comprise the Full Analysis Set (FAS). Safety, according to the number and severity of adverse effects (AEs), was evaluated in the safety (SAF) population, composed by patients with at least one adjunct HIVEC MMC instillation; (3) Results: The FAS population (n = 502) received a median number of 8.78 ± 3.28 (range 1–20) HIVEC MMC instillations. The median follow-up duration was 24.5 ± 16.5 (range 1–81) months. Its distribution, based on EAU risk stratification, was 297 (59.2%) for intermediate and 205 (40.8%) for high-risk. The figures for five-year recurrence-free and progression-free survival were 50.37% (53.3% for intermediate and 47.14% for high-risk) and 89.83% (94.02% for intermediate and 84.23% for high-risk), respectively. A multivariate analysis identified recurrent tumors (HR 1.83), the duration of adjuvant HIVEC therapy <4 months (HR 1.72) and that high-risk group (HR 1.47) were at an increased risk of recurrence. Independent factors of progression were high-risk (HR 3.89), recurrent tumors (HR 3.32) and the induction of HIVEC therapy without maintenance (HR 2.37). The overall survival was determined by patient age at diagnosis (HR 3.36) and the treatment duration (HR 1.82). The SAF population (n = 592) revealed 406 (68.58%) patients without AEs and 186 (31.42%) with at least one AE: 170 (28.72%) of grade 1–2 and 16 (2.7%) of grade 3–4. The most frequent AEs were dysuria (10%), pain (7.1%), urgency (5.7%), skin rash (4.9%), spasms (3.7%) and hematuria (3.6%); (4) Conclusions: HIVEC using BRS is efficacious and well tolerated. A longer treatment duration, its use in naïve patients and the intermediate-risk disease are independent determinants of success. Furthermore, a monthly maintenance of adjunct MMC HIVEC diminishes the progression rate of NMIBC.

Intravesical mitomycin C (MMC) and MMC + cytosine arabinoside for non-muscle-invasive bladder cancer: a randomised clinical trial. BJU Int 2021; 129:534-541. [PMID: 34383381 PMCID: PMC9290455 DOI: 10.1111/bju.15571] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2021] [Revised: 07/29/2021] [Accepted: 08/07/2021] [Indexed: 12/01/2022]
Abstract
Objectives To compare the urinary pH, recurrence‐free survival (RFS), and safety of adjuvant intravesical therapy in patients with non‐muscle‐invasive bladder cancer (NMIBC) receiving mitomycin C (MMC) therapy and MMC + cytosine arabinoside (Ara‐C) therapy. Patients and Methods A total of 165 patients with NMIBC from six hospitals were randomly allocated to two groups: weekly instillation of MMC + Ara‐C (30 mg/30 mL + 200 mg/10 mL) for 6 weeks and the same instillation schedule of MMC (30 mg/40 mL). The primary outcome was RFS, and secondary outcomes were urinary pH and toxicity in the two groups. Results A total of 81 and 87 patients were randomised into the MMC and MMC + Ara‐C groups, respectively. Overall, the RFS in the MMC + Ara‐C group was significantly longer (P = 0.018) than that in the MMC group. A similar significant difference was detected in patients with intermediate‐risk NMIBC, but not in those with high‐risk NMIBC. The mean (SD) urinary pH was significantly higher in the MMC + Ara‐C group than in the MMC group, at 6.56 (0.61) vs 5.78 (0.64) (P < 0.001), and the frequency of a urinary pH of >7.0 in the MMC and MMC + Ara‐C groups was 6.3% and 26.7%, respectively (P < 0.001). Multivariate analysis models including clinicopathological features and second transurethral resection demonstrated that increased urinary pH was associated with better outcomes (hazard ratio 0.18, 95% confidential interval 0.18–0.038; P < 0.001). In all, there were 14 and 10 adverse events in the MMC and MMC + Ara‐C groups, respectively, without a significant difference (P = 0.113). Conclusions Our randomised clinical trial suggested that intravesical therapy with MMC and Ara‐C is useful and safe for patients with intermediate‐risk NMIBC. Increase in urinary pH with Ara‐C is speculated as a mechanism for increased anti‐cancer effects.

Low Risk of Severe Complications After a Single, Post-Operative Instillation of Intravesical Chemotherapy in Patients with TaG1G2 Urothelial Bladder Carcinoma. Bladder Cancer 2021. [DOI: 10.3233/blc-201515] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/15/2022]
Abstract
BACKGROUND: EAU guidelines recommend a single instillation (SI) of intravesical chemotherapy (e.g. Mitomycin C) within 24 hours after transurethral resection of a bladder tumour (TURBT) in patients with low- to intermediate risk non-muscle invasive bladder cancer without (suspected) bladder perforation or bleeding requiring bladder irrigation. However, remarkable variation exists in the use of SI. The risk of severe complications is likely to contribute to this variation, but evidence is limited. OBJECTIVE: To investigate the absolute severe complication and mortality risk after SI in low- and intermediate risk bladder cancer. METHODS: In this observational, historic cohort study, data on 25,567 patients diagnosed with TaG1G2 urothelial bladder carcinoma (UBC) between 2009 and 2018 who underwent TURBT were collected from the Netherlands Cancer Registry. Data were supplemented with information on cause of death and severe complications after cancer treatment by re-examining the electronic health records and the 14-day complication risk and the 30-day mortality risk were evaluated. RESULTS: On average, 55% of patients had a SI after TURBT, varying from 0–>80% between hospitals. The 30-day mortality risk was 0.02% and the 14-day risk of severe complications was 1.6%. CONCLUSIONS: As the absolute risk of mortality and severe complications is very low, SI after TURBT can be considered a safe treatment in patients with low- to intermediate UBC without contraindications for SI. These results imply that a part of eligible patients is denied effective treatment.

Guideline adherence for radical cystectomy significantly affects survival outcomes in non-muscle-invasive bladder cancer patients. Jpn J Clin Oncol 2021; 51:1303-1312.

Abstract
BACKGROUND The relationship between guideline adherence for radical cystectomy of non-muscle-invasive bladder cancer and patient prognoses currently remains unclear. We investigated whether guideline adherence at the time of non-muscle-invasive bladder cancer affects the oncological outcomes of bladder cancer patients who underwent radical cystectomy. METHODS Among 267 cTa-4N0-2M0 bladder cancer patients, 70 who underwent radical cystectomy under the non-muscle-invasive bladder cancer or muscle-invasive bladder cancer status that progressed from non-muscle-invasive bladder cancer were identified. Patients who followed the guidelines from initial transurethral resection of bladder tumors to radical cystectomy were defined as the guideline adherent group (n = 52), while those who did not were the guideline non-adherent group (n = 18). RESULTS In the guideline non-adherent group, 8 (44.4%) out of 18 were diagnosed with highest risk non-muscle-invasive bladder cancer for Bacillus Calmette Guérin-naïve patients and 7 (38.9%) had a Bacillus Calmette Guérin unresponsive tumor status. Five-year recurrence-free survival and cancer-specific survival rates for the guideline non-adherent group vs guideline adherent group were 38.9% vs 69.8% (P = 0.018) and 52.7% vs 80.1% (P = 0.006), respectively. A multivariate analysis identified guideline non-adherence as one of independent indicators for disease recurrence (hazard ratio = 2.81, P = 0.008) and cancer-specific death (hazard ratio = 4.04, P = 0.003). In a subgroup analysis of 49 patients with cT1 or less non-muscle-invasive bladder cancer at the time of radical cystectomy, guideline non-adherence remained an independent prognostic factor for cancer-specific survival (hazard ratio = 3.46, P = 0.027). CONCLUSIONS Guideline adherence during the time course of the non-muscle-invasive bladder cancer stage may result in a favorable prognosis of patients who receive radical cystectomy. Even under non-muscle-invasive bladder cancer status, radical cystectomy needs to be performed with adequate timing under guideline recommendations.

The Management of Newly-Diagnosed Non-muscle Invasive Bladder Cancer in Veterans Integrated Services Network 02 of the Veterans Health Administration. Mil Med 2021; 185:276-281. [PMID: 31294791 DOI: 10.1093/milmed/usz166] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2019] [Revised: 06/04/2019] [Accepted: 06/12/2019] [Indexed: 11/12/2022] Open
Abstract
INTRODUCTION Over 1,500 bladder cancers were diagnosed among US Veterans in 2010, the majority of which were non-muscle invasive bladder cancer (NMIBC). Little is known about NMIBC treatment within the Veterans Health Administration. The objective of the study was to assess the quality of care for Veterans with newly-diagnosed NMIBC within Veterans Integrated Service Network (VISN) 02. MATERIALS AND METHODS We used ICD-9 and ICD-10 codes to identify patients with newly-diagnosed bladder cancer from 1/2016-8/2017. We risk-stratified the patients into low, intermediate, and high-risk based on the 2016 American Urological Association Guidelines on NMIBC. Our primary objectives were percentages of transurethral resection of bladder tumors (TURBTs) with detrusor, repeat TURBT in high-risk and T1 disease, high-risk NMIBC treated with induction intravesical therapy (IVT), and responders treated with maintenance IVT. We performed logistic regression for association between distance to diagnosing hospital and receipt of induction IVT in high-risk patients. RESULTS There were 121 newly-diagnosed NMIBC patients; 16% low-risk, 28% intermediate-risk, and 56% high-risk. Detrusor was present in 80% of all initial TURBTs and 84% of high-risk patients. Repeat TURBT was performed in 56% of high-risk NMIBC and 60% of T1. Induction IVT was given to 66% of high-risk patients and maintenance IVT was given to 59% of responders. On multivariate logistic regression, distance to medical center was not associated with receipt of induction IVT (OR = 0.99, 95% CI [0.97,1.01], p = 0.52). CONCLUSIONS We observed high rates of sampling of detrusor in the first TURBT specimen, utilization of repeat TURBT, and administration of induction and maintenance intravesical BCG for high-risk patients among a regional cohort of US Veterans with NMIBC. While not a comparative study, our findings suggest high quality NMIBC care in VA VISN 02.

Intravesical Therapy in Patients with Intermediate-risk Non-muscle-invasive Bladder Cancer: A Systematic Review and Network Meta-analysis of Disease Recurrence. Eur Urol Focus 2021; 8:447-456. [PMID: 33762203 DOI: 10.1016/j.euf.2021.03.016] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2021] [Revised: 02/11/2021] [Accepted: 03/10/2021] [Indexed: 12/09/2022]
Abstract
CONTEXT Patients with intermediate-risk non-muscle-invasive bladder cancer (NMIBC) may pose a clinical dilemma without an agreed evidence-based decision tree for personalized treatment. OBJECTIVE To perform a systematic review and network meta-analysis (NMA) to summarize available evidence on the oncologic outcomes of intravesical therapy in patients with intermediate-risk NMIBC. EVIDENCE ACQUISITION The MEDLINE, EMBASE, and ClinicalTrials.gov databases were searched in October 2020 according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. Studies were deemed eligible if they reported on oncologic outcomes in patients with intermediate-risk NMIBC treated with transurethral resection of bladder tumor with and without intravesical chemotherapy or bacillus Calmette-Guérin (BCG) immunotherapy. EVIDENCE SYNTHESIS Twelve studies were included in a qualitative synthesis (systematic review); three were deemed eligible for a quantitative synthesis (NMA). An NMA of five different regimens was conducted for the association of treatment with the 5-yr recurrence risk. Chemotherapy with maintenance was associated with a lower likelihood of 5-yr recurrence than chemotherapy without maintenance (odds ratio [OR] 0.51, 95% credible interval [CI] 0.26-1.03). Immunotherapy, regardless of whether a full- or reduced-dose regimen, was not associated with a significantly lower likelihood of 5-yr recurrence when compared with chemotherapy without maintenance (OR 0.90, 95% CI 0.39-2.11 vs OR 0.93, 95% CI 0.40-2.19). Analysis of the treatment ranking revealed that chemotherapy with maintenance had the lowest 5-yr recurrence risk (P score 0.9666). CONCLUSIONS Our analysis indicates that chemotherapy with a maintenance regimen confers a superior oncologic benefit in terms of 5-yr recurrence risk compared to chemotherapy without maintenance in patients with intermediate-risk NMIBC. Regardless of the dose regimen, immunotherapy with BCG does not appear to be superior to chemotherapy in patients with intermediate-risk NMIBC in term of disease recurrence. However, owing to the lack of comparative studies, there is an unmet need for well-designed, large-scale trials to validate our findings and generate robust evidence on disease recurrence and progression. PATIENT SUMMARY A maintenance schedule of chemotherapy reduces the rate of long-term recurrence of bladder cancer that has not invaded the bladder muscle. Chemotherapy inserted directly into the bladder and immunotherapy without maintenance schedules seem to have limited benefit in preventing cancer recurrence.

Abstract
OBJECTIVE This literature review provides an overview of non-muscle-invasive bladder cancer diagnosis (NMIBC), treatment, and surveillance. Existing evidence is reviewed to identify the NMIBC patient pathway, highlight its effect on quality of life, and identify supportive care needs of this patient group. A framework to guide nurses in the care of this underserved population is proposed. DATA SOURCES Electronic databases including CINAHL, Medline, PsychInfo, Cochrane, and Google Scholar were searched. CONCLUSION NMIBC is a chronic disease with high recurrence and progression rates with most patients requiring invasive treatment and burdensome surveillance schedules with frequent hospital visits. Treatment-related side effects may interrupt therapy and possibly result in its discontinuation. Patients' quality of life can be negatively affected at various stages of the cancer trajectory. Specialist nurses provide holistic care throughout all stages of the patient journey to optimize supportive care, information provision, and delivery of appropriate treatment and surveillance protocols. NMIBC research is historically underfunded with a paucity of evidence identifying the supportive care needs of this population. Further research is urgently required to fill the gaps identified. IMPLICATIONS FOR NURSING PRACTICE This timely paper raises the profile of unmet supportive care needs in an underserved research cancer population. Suggestions are proposed to improve the quality of nursing care through standardized practices and the development and integration of patient pathways. Evidence of the effect of NMIBC on family members or carers is absent from the literature. Future research implications and directions are proposed.

Abstract
INTRODUCTION Urolithiasis is a common diagnosis in urology. New technologies offer a variety of diagnostic and therapy and consequently display a financial burden on healthcare systems. Hence, clinical practice guidelines (CPG) are essential to implement evidence-based medicine and assure a standard of care considering limited resources. To date, there is no evidence of the use and adherence to CPG on urolithiasis. MATERIAL AND METHODS Therefore, we performed a cross-sectional study to analyze the use of CPG on urolithiasis. Data collection was carried out by a questionnaire given to 400 German urologists. The survey included use and adherence to guidelines, evaluation of the clinical situation, therapy spectrum, and workplace. In total, 150 (37%) questionnaires were received and included in our survey. Statistics were performed by SPSS using Chi-quadrat test/Fisher's exact test. RESULTS In our study, urologists were office based, hospital affiliated, non-academic, or academic centers in 53%, 32%, 16% and 5%, respectively. In 74% and 70%, urologists adhere to CPG in diagnostic and therapy. Interestingly, workplace and therapy spectrum determines the use of different CPG (p = 0.01; p = 0.022). Academic urologists were more likely to use international CPG of EAU (40%), while outpatient urologists significantly orientated on national CPG (46%). 86% of urologists with high volume of urolithiasis practice interventions in contrast to 53% in low volume (p = 0.001). More than 80% of urologists use short versions and app version of CPG. CONCLUSION We firstly describe compliance and the use of CPG on urolithiasis. EAU and DGU present the most commonly used CPG. Short version and app version of CPG find frequent clinical utilization.

Abstract
PURPOSE Non-muscle invasive bladder cancer (NMIBC) is a malignancy restricted to the inner lining of the bladder. Intravesical Bacillus Calmette-Guerin (BCG) following transurethral resection of the bladder tumor is the mainstay first-line treatment for high-risk NMIBC patients. Two systematic literature reviews (SLRs) were conducted to further assess the current evidence on BCG use in NMIBC and the humanistic and economic burden of disease. METHODS Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, Embase® and MEDLINE® were searched using the Ovid platform to identify interventional or real-world evidence studies on the health-related quality of life (HRQoL) and economic burden in NMIBC. Limited evidence was found from initial economic SLR searches in NMIBC, so additional targeted searches for bladder cancer were conducted to expand findings. RESULTS Fifty-nine publications were included in the HRQoL SLR, of which 23 reported HRQoL and symptoms in NMIBC. At diagnosis, HRQoL was comparable with population norms but worsened considerably 2 years following diagnosis. Maintenance therapy with intravesical BCG was associated with reduced HRQoL, and treatment-related adverse events (AEs) resembled typical NMIBC symptoms. Twenty-two studies reported decreasing BCG compliance over time. Common AEs with BCG were frequent urination, lower urinary tract symptoms, pain, and hematuria. Forty-two publications were included in the economic SLR, of which nine assessed healthcare costs and resource use in NMIBC or bladder cancer. High-risk disease and high-intensity treatment were associated with increased healthcare costs. CONCLUSION NMIBC has a considerable symptomatic, HRQoL, and economic burden. Symptoms persisted and HRQoL worsened despite intravesical BCG treatment. NMIBC is a costly disease, with higher healthcare costs associated with increased risk of disease progression and recurrence. There is a high unmet need for safe and effective treatments that reduce the risk of disease progression and recurrence, provide symptomatic relief, and improve HRQoL for patients.

Abstract
PURPOSE This systematic review assessed compliance to guidelines for the management of nonmuscle-invasive bladder carcinoma (NMIBC). METHODS The PUBMED, Web of Science, Cochrane Library, and Scopus databases were searched in November 2019 in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis statement. RESULTS Fifteen studies incorporating a collective total of 10,575 NMIBC patients were eligible for inclusion in this systematic review. We found that the rates of compliance were 53.0% with a single immediate intravesical instillation in patients with presumed low or intermediate risk, 37.1% with intravesical bacillus Calmette-Guerin or chemotherapy in those with intermediate risk, 43.4% with performance of a second transurethral resection in high-risk patients, 32.5% with administration of adjuvant intravesical bacillus Calmette-Guerin in high-risk patients, 36.1% with radical cystectomy in highest-risk patients, and 82.2% with cystoscopy for follow-up. CONCLUSIONS Compliance with NMIBC guidelines remains low. Better guideline education and understanding holds the key to achieving high compliance. Strategies to improve guideline compliance at the physician level are urgently required.

Variability in adherence to guidelines based management of nonmuscle invasive bladder cancer among Society of Urologic Oncology (SUO) members. Urol Oncol 2020; 38:796.e1-796.e6. [PMID: 32430255 DOI: 10.1016/j.urolonc.2020.04.026] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2020] [Revised: 03/25/2020] [Accepted: 04/24/2020] [Indexed: 01/08/2023]
Abstract
PURPOSE The American Urological Association (AUA) introduced evidence-based guidelines for the management of nonmuscle invasive bladder cancer (NMIBC) in 2016. We sought to assess the implementation of these guidelines among members of the Society of Urologic Oncology (SUO) with an aim to identifying addressable gaps. METHODS AND MATERIALS An SUO approved survey was distributed to 747 members from December 28, 2018 to February 2, 2019. This 14-question online survey (Qualtrics, SAP SE, Germany) consisted of 38 individual items addressing specific statements from the AUA NMIBC guidelines within 3 broad categories - initial diagnosis, surveillance, and imaging/biomarkers. Adherence to guidelines was assessed by dichotomizing responses to each item that was related to recommended action statement within the guidelines. Statistical analysis was applied using Pearson's chi-squared test, where a P-value of <0.05 was considered statistically significant. RESULTS A total of 121 (16.2%) members completed the survey. Members reported a mean of 71% guidelines adherence; adherence was higher for the intermediate- and high-risk subgroups (82% and 76%, respectively) compared to low-risk (58%). Specifically, adherence to guideline recommended cystoscopic surveillance intervals for low-risk disease differed based on clinical experience (60.9% [<10 years] vs. 36.8% [≥10 years], P = 0.01) and type of fellowship training (55.2% [urologic oncology] vs. 28.0% [none/other], P = 0.02). CONCLUSION Adherence to guidelines across risk-categories was higher for intermediate- and high-risk patients. Decreased adherence observed for low-risk patients resulted in higher than recommended use of cytology, imaging, and surveillance cystoscopy. These results identify addressable gaps and provide impetus for targeted interventions to support high-value care, especially for low-risk patients.

Abstract
Physicians treating patients affected by nonmuscle-invasive bladder cancer (NMIBC) have been in shock during the last six years since manufacturing restrictions on the production of the first-option medicine, Mycobacterium bovis Bacillus Calmette-Guérin (BCG), have resulted in worldwide shortages. This shortage of BCG has led to a rethinking of the established treatment guidelines for the rationing of the administration of BCG. Some possible schedule modifications consist of a decrease in the length of maintenance treatment, a reduction in the dose of BCG in intravesical instillations or the use of different BCG substrains. All these strategies have been considered valuable in times of BCG shortage. In addition, the lack of availability of BCG has also led to the general recognition of the need to find new treatment options for these patients so that they are not dependent on a single treatment. Few alternatives are committed to definitively replacing BCG intravesical instillations, but several options are being evaluated to improve its efficacy or to combine it with other chemotherapeutic or immunotherapeutic options that can also improve its effect. In this article, we review the current state of the treatment with BCG in terms of all of the aforementioned aspects.

Factors affecting guideline adherence in the initial treatment of non-muscle invasive bladder cancer: Retrospective study in a French peripheral hospital. Prog Urol 2019; 30:26-34. [PMID: 31813714 DOI: 10.1016/j.purol.2019.11.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2019] [Revised: 09/10/2019] [Accepted: 11/07/2019] [Indexed: 10/25/2022]
Abstract
OBJECTIVES To assess whether the initial treatment of non-muscle invasive bladder cancer (NMIBC) was performed according to the guidelines, and to determine the reasons why initial treatment was not provided in nonadherence cases. MATERIALS AND METHODS We retrospectively reviewed all patients with NMIBC who underwent their first transurethral resection of bladder tumor (TURBT) at a peripheral hospital, between 2007 and 2016. The treatment offered to the patient was compared to the European Association of Urology guidelines according to risk stratification. For each patient who did not receive the treatment according to the guidelines, one of the following reasons was identified: poor patient compliance, poor patient general health status, urologist's decision, lack of resources. RESULTS One hundred fifty-nine patients were included with a mean age of 72.2 years at the time of NMIBC diagnosis. The low-risk patients were strictly treated according to the guidelines. Among the intermediate-risk patients, 14% received mitomycin C. Among the high-risk patients, 39% received intravesical Bacillus Calmette-Guerin. In the nonadherence cases (61%), the reasons were related to the patient in 44% of cases (poor compliance, 21%; poor patient general health status, 23%), urologist's decision in 54% of cases, and lack of resources in 2% of cases. Thirty-seven percent of the high-risk patients underwent re-resection. CONCLUSIONS Overall, adherence to NMIBC guidelines was low in all treatment types (intravesical therapy, re-resection, or cystectomy for very high-risk patients), but this finding was similar to that in previous studies. Reasons were mainly related to the urologist's decision or to the patient condition (poor compliance or poor general health status). LEVEL OF EVIDENCE 3.

Abstract
BACKGROUND Photodynamic diagnosis using the optical imaging agent hexaminolevulinate (HAL, Hexvix®, Ipsen Pharma GmbH, Ettlingen, Germany) as an adjunct to white light cystoscopy (WLC) during the initial transurethral resection of bladder tumours (TURB) improves the detection rate of bladder cancer and leads to fewer recurrences. OBJECTIVES A cost-effectiveness analysis was carried out in order to calculate the consequences for the German healthcare system. METHODS We combined a short-term decision tree and a Markov model to evaluate outcomes over a long period of time. The alternatives investigated were HAL-assisted blue light cystoscopy (BLC) as adjunct to WLC (HAL + BLC/WLC) compared with WLC alone in patients undergoing TURB. RESULTS HAL + BLC/WLC compared to WLC alone was associated with 0.07 incremental quality-adjusted life years (QALYs) and cost savings of 537 € per patient. CONCLUSION HAL + BLC/WLC compared with WLC alone resulted in both cost savings and improved patient outcome rendering it the "dominant" strategy.

Abstract
AIM To define and present explanations for the epidemiological, pathological and prognostic differences in bladder cancer in elderly patients. METHOD Bibliographical search was performed from the Medline bibliographic database (NLM Pubmed tool) and Embase focused on: bladder cancer, carcinogenesis, elderly, epidemiology, prognosis. RESULTS Bladder cancer is a growing concern for the elderly first and foremost and with an impact, mainly those who are consumers or former users of tobacco, whose therefore frequently have comorbidities associated with this consumption. The initiated carcinogenesis extends with the life length of patients, increasing the prevalence of bladder cancer. Aging promotes carcinogenesis by both potentiating its genetic abnormalities and reducing the immune system performance of the aged host to destroy cancer cells. The delay in the diagnosis of bladder cancer in elderly patients is explained and make up for the time could improve the prognosis. CONCLUSION Regardless of variations in therapeutic effect and morbidity and mortality of treatments, aging promotes the occurrence and aggressiveness of bladder cancer. The incentive to stop exposure to carcinogens and the search for bladder cancer in patients with hematuria should not reduce with advanced age but instead be promoted in order to improve the prognosis.

Abstract
Because of its proven efficacy, intravesical Bacillus Calmette-Guérin (BCG) immunotherapy is an important treatment for nonmuscle invasive bladder cancer at high risk of recurrence or progression. However, approximately 8% of patients have to stop BCG instillation as a result of its complications. Complications induced by BCG therapy can have a variety of clinical manifestations. These adverse reactions may occur in conjunction with BCG instillation or may not develop until months or years after BCG cessation. An essential step in the management complications arising from BCG is early establishment of diagnosis, particularly for distant, disseminated, and obscure infections. Therefore we reviewed the literature on the potential complications after intravesical BCG immunotherapy for bladder cancer and provide an overview on the incidence, diagnosis, and treatment modality of genitourinary and systemic BCG-induced complications.

Abstract
Intravesical immunotherapy with bacillus Calmette-Guérin (BCG) is the standard of care for high-risk and intermediate-risk non-muscle-invasive bladder cancer (NMIBC). Several BCG strains are available. Despite originating all from subcultures of the same Mycobacterium, strains are genetically different which may lead to differences in treatment efficacy and adverse events. Identification of a more efficient strain and assessing its optimal administration schedule may improve oncological outcomes in NMIBC, specifically because of the worldwide shortage in BCG availability. This review focused on the antitumor effect of different BCG strains with a particular emphasis on the evidence underlying BCG dose and treatment schedules.

Abstract
BACKGROUND A fast, noninvasive test with high sensitivity (SN) and a negative predictive value (NPV), which is able to detect recurrences in bladder cancer (BC) patients, is needed. A newly developed urine assay, Xpert Bladder Cancer Monitor (Xpert), measures five mRNA targets (ABL1, CRH, IGF2, UPK1B, and ANXA10) that are frequently overexpressed in BC. OBJECTIVE To validate Xpert characteristics in patients previously diagnosed with non-muscle-invasive BC. DESIGN, SETTING, AND PARTICIPANTS Voided precystoscopy urine samples were prospectively collected at 22 sites. Xpert, cytology, and UroVysion were performed. If cystoscopy was suspicious for BC, a histologic examination was performed. Additionally, technical validation was performed and specificity was determined in patients without a history or clinical evidence of BC. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Test characteristics were calculated based on cystoscopy and histology results, and compared between Xpert, cytology, and UroVysion. RESULTS AND LIMITATIONS Of the eligible patients, 239 with a history of BC had results for all assays. The mean age was 71 yr; 190 patients were male, 53 never smoked, and 64% had previous intravesical immunotherapy (35%) or chemotherapy (29%). Forty-three cases of recurrences occurred. Xpert had overall SN of 74% (95% confidence interval [CI]: 60-85) and 83% (95% CI: 64-93) for high-grade (HG) tumors. The NPV was 93% (95% CI: 89-96) overall and 98% (95% CI: 94-99) for HG tumors. Specificity was 80% (95% CI: 73-85). Xpert SN and NPV were superior to those of cytology and UroVysion. Specificity in non-BC individuals (n=508) was 95% (95% CI: 93-97). CONCLUSIONS Xpert has an improved NPV compared with UroVysion and cytology in patients under follow-up for BC. It represents a promising tool for excluding BC in these patients, reducing the need for cystoscopy. PATIENT SUMMARY Xpert is an easy-to-perform urine test with good performance compared with standard urine tests. It should help optimize the follow-up of recurrent bladder cancer patients.

Abstract
INTRODUCTION Intravesical therapy has been an important aspect of the management of non-muscle invasive bladder cancer (NMIBC) for 40 years. Bacillus Calmette-Guerin (BCG) is considered standard of care for intermediate and high-grade non-invasive disease, yet understanding the nuances of subsequent intravesical therapy is important for any provider managing bladder cancer. Herein, we review the literature and describe optimal use of intravesical therapies for NMIBC. METHODS A comprehensive search of the medical literature was performed and highlighted in this review of intravesical therapy for NMIBC. RESULTS Post-resection intravesical Mitomycin C therapy for low-risk disease remains an important component of care, and gemcitabine now has level-one evidence demonstrating efficacy in this setting but is not yet a guideline recommendation. BCG intravesical therapy remains the most effective therapy preventing recurrence and progression of intermediate and high-risk NMIBC. Adequately characterizing BCG-failure is critical in determining the next step in management which includes radical cystectomy, additional intravesical immunotherapy, chemotherapy with intravesical gemcitabine ± docetaxel and clinical trials. CONCLUSIONS Intravesical therapy remains the mainstay of treatment for NMIBC and bladder preservation. Intravesical induction BCG followed by maintenance therapy remains standard of care for intermediate and high-risk patients. Detailing the timing and characteristics of recurrence after intravesical therapy is crucial in determining subsequent treatment recommendations. Current clinical trials focus on systemic immunotherapy and enhancing the intravesical immune response by augmenting the delivery mechanism.

Abstract
FGFR3 alterations (mutations or translocation) are among the most frequent genetic events in bladder carcinoma. They lead to an aberrant activation of FGFR3 signaling, conferring an oncogenic dependence, which we studied here. We discovered a positive feedback loop, in which the activation of p38 and AKT downstream from the altered FGFR3 upregulates MYC mRNA levels and stabilizes MYC protein, respectively, leading to the accumulation of MYC, which directly upregulates FGFR3 expression by binding to active enhancers upstream from FGFR3 Disruption of this FGFR3/MYC loop in bladder cancer cell lines by treatment with FGFR3, p38, AKT, or BET bromodomain inhibitors (JQ1) preventing MYC transcription decreased cell viability in vitro and tumor growth in vivo A relevance of this loop to human bladder tumors was supported by the positive correlation between FGFR3 and MYC levels in tumors bearing FGFR3 mutations, and the decrease in FGFR3 and MYC levels following anti-FGFR treatment in a PDX model bearing an FGFR3 mutation. These findings open up new possibilities for the treatment of bladder tumors displaying aberrant FGFR3 activation.

Abstract
The European Association of Urology (EAU) annually updates 21 clinical practice guidelines in which summaries of the evidence base and best practice recommendations are made. The methodology applied to achieve this and integrate stakeholder opinion is continuously improving. However, there is evidence to suggest wide variation in clinical practice indicating that many patients receive suboptimal and heterogeneous care. Studies from certain countries suggest that 2 out of 5 patients do not receive care according to the current scientific evidence, and in 1 out of 4 cases the care provided is potentially harmful. Clearly, the harmonisation of care in alignment with evidence-based best practice recommendations is something to strive for. Development of robust methods to disseminate and implement guideline recommendations and measure their impact is an objective the EAU is committed to improving. An important strategy for achieving harmonisation in urological care across Europe is to ensure the availability of high-quality clinical practice guidelines and to actively promote their implementation by clinicians and healthcare providers.

Discrepancy Between European Association of Urology Guidelines and Daily Practice in the Management of Non-muscle-invasive Bladder Cancer: Results of a European Survey. Eur Urol Focus 2017; 5:681-688. [PMID: 29074050 DOI: 10.1016/j.euf.2017.09.002] [Citation(s) in RCA: 33] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2017] [Revised: 08/04/2017] [Accepted: 09/03/2017] [Indexed: 11/15/2022]
Abstract
BACKGROUND The European Association of Urology (EAU) non-muscle-invasive bladder cancer (NMIBC) guidelines are meant to help minimise morbidity and improve the care of patients with NMIBC. However, there may be underuse of guideline-recommended care in this potentially curable cohort. OBJECTIVE To assess European physicians' current practice in the management of NMIBC and evaluate its concordance with the EAU 2013 guidelines. DESIGN, SETTING, AND PARTICIPANTS Initial 45-min telephone interviews were conducted with 20 urologists to develop a 26-item questionnaire for a 30-min online quantitative interview. A total of 498 physicians with predefined experience in treatment of NMIBC patients, from nine European countries, completed the online interviews. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Descriptive statistics of absolute numbers and percentages of the use of diagnostic tools, risk group stratification, treatment options chosen, and follow-up regimens were used. RESULTS AND LIMITATIONS Guidelines are used by ≥87% of physicians, with the EAU guidelines being the most used ones (71-100%). Cystoscopy (60-97%) and ultrasonography (42-95%) are the most used diagnostic techniques. Using EAU risk classification, 40-69% and 88-100% of physicians correctly identify all the prognostic factors for low- and high-risk tumours, respectively. Re-transurethral resection of the bladder tumour (re-TURB) is performed in 25-75% of low-risk and 55-98% of high-risk patients. Between 21% and 88% of patients received a single instillation of chemotherapy within 24h after TURB. Adjuvant intravesical treatment is not given to 6-62%, 2-33%, and 1-20% of the patients with low-, intermediate-, and high-risk NMIBC, respectively. Patients with low-risk NMIBC are likely to be overmonitored and those with high-risk NMIBC undermonitored. Our study is limited by the possible recall bias of the selected physicians. CONCLUSIONS Although most European physicians claim to apply the EAU guidelines, adherence to them is low in daily practice. PATIENT SUMMARY Our survey among European physicians investigated discrepancies between guidelines and daily practice in the management of non-muscle-invasive bladder cancer (NMIBC). We conclude that the use of the recommended diagnostic tools, risk-stratification of NMIBC, and performance of re-TURB have been adopted, but adjuvant intravesical treatment and follow-up are not uniformly applied.

Abstract
PURPOSE To characterize outcomes of patients with TaT1 urothelial carcinoma of the bladder stratified by the European Association of Urology (EAU) categories and to compare them with European Organization for Research and Treatment of Cancer (EORTC) risk groups to assess the rate and effect of reclassification. PATIENTS AND METHODS A multi-institutional database of 5,122 patients with TaT1 urothelial carcinoma of the bladder who underwent transurethral resection of the bladder with or without adjuvant therapy at 8 institutions between 1996 and 2007. Multivariable Cox-regression analyses addressed factors associated with disease recurrence and progression. The net reclassification index was used to compare the performance of the EAU categories with the EORTC scoring system. RESULTS Of 5,122 patients, 632 (12.3%), 2,302 (45.0%), and 2,188 (42.7%) were assigned to the low-, intermediate-, and high-risk EAU category, respectively. Within a median follow-up of 62 months (interquartile range: 27-97), 2,365 (46.2%) and 516 (10.1%) patients experienced disease recurrence and progression, respectively. In multivariable Cox-regression analyses, EAU intermediate- and high-risk categories were associated with a higher risk of disease recurrence (P<0.001) and progression (P<0.001) compared to low-risk patients. Application of the EAU categories reclassified 1,940 (37.9%) patients into a higher risk group for recurrence. Likewise, 602 (11.8%) patients were reclassified to a higher and 278 (5.4%) to a lower risk group for progression. The net reclassification index of the EAU risk stratification was 0.1% (95% CI: -3.1% to 3.2%) for recurrence and 10.1% (95% CI: -8.0% to 12.0%) for progression, respectively. CONCLUSIONS Compared to EORTC risk stratification, the EAU categories reclassifies 37.9% patients into a higher risk group of recurrence and 11.8% into a higher risk of progression. However, the novel risk stratification assigns most patients to the same treatment as the more complex EORTC tables and can be regarded as an alternative tool for treatment decision-making.

Abstract
The standard of care for most patients with non-muscle-invasive bladder cancer (NMIBC) is immunotherapy with intravesical Bacillus Calmette-Guérin (BCG), which activates the immune system to recognize and destroy malignant cells and has demonstrated durable clinical benefit. Urologic best-practice guidelines and consensus reports have been developed and strengthened based on data on the timing, dose, and duration of therapy from randomized clinical trials, as well as by critical evaluation of criteria for progression. However, these reports have not penetrated the community, and many patients do not receive appropriate therapy. Additionally, several immune checkpoint inhibitors have recently been approved for treatment of metastatic disease. The approval of immune checkpoint blockade for patients with platinum-resistant or -ineligible metastatic bladder cancer has led to considerations of expanded use for both advanced and, potentially, localized disease. To address these issues and others surrounding the appropriate use of immunotherapy for the treatment of bladder cancer, the Society for Immunotherapy of Cancer (SITC) convened a Task Force of experts, including physicians, patient advocates, and nurses, to address issues related to patient selection, toxicity management, clinical endpoints, as well as the combination and sequencing of therapies. Following the standard approach established by the Society for other cancers, a systematic literature review and analysis of data, combined with consensus voting was used to generate guidelines. Here, we provide a consensus statement for the use of immunotherapy in patients with bladder cancer, with plans to update these recommendations as the field progresses.

'Real-life experience': recurrence rate at 3 years with Hexvix ® photodynamic diagnosis-assisted TURBT compared with good quality white light TURBT in new NMIBC-a prospective controlled study. World J Urol 2017; 35:1871-1877. [PMID: 28803385 PMCID: PMC5693980 DOI: 10.1007/s00345-017-2077-6] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2017] [Accepted: 07/31/2017] [Indexed: 11/24/2022] Open
Abstract
Purpose To compare the recurrence rate at 3 years (RR-3y) for non-muscle invasive bladder cancer (NMIBC) between good quality (GQ) PDD-TURBT and GQWL-TURBT where PDD is used in routine practice for all new tumours. Methods All new, consecutive, NMIBC that received “good quality” criteria first TURBT across a university hospital service were prospectively recruited to this study over a 4-year period. Data were prospectively collected on all WL-TURBTs performed in 2007/8 and compared with PDD-TURBT from 2009/10. Only resection meeting strict “good quality criteria” were included from each cohort to control for resection quality, then cases were further matched 1:1 based on demographic and pathological criteria. The primary outcome was overall and risk group-specific recurrence rate at 3 years. Results Of 808 patients recruited, 345 had GQ-TURBT for NMIBC and were included. RR-3y was significantly less for GQ-PDD overall [RR-3y: GQ-PDD: 57/146 (39.0%), GQ-WL: 72/135 (53.3%) OR = 0.56 (0.35–0.90) p = 0.02] and on a 1:1 matched pair basis [RR GQ-PDD: 29/118 (24.6) vs. 59/118 (50.0) OR 0.33 (0.19–0.57) p < 0.001)]. Benefit was most marked in high-risk patients: RR-3y in high-risk patients treated with GQ-PDD was 25/48 (52.1%) vs. 28/35 (80%) for GQ-WL [OR 0.27 (0.10–0.74) p = 0.01]. Conclusion When adopted for all new bladder tumour resections in routine practice, PDD appears to be associated with significantly reduced recurrence rates at 3 years in our “real life” experience, particularly in high-risk patients.

Abstract
OBJECTIVE The aim of this study was to evaluate the use of intravesical treatment and cancer-specific survival of patients with primary carcinoma in situ (CIS). MATERIALS AND METHODS Data acquisition was based on the Swedish National Registry of Urinary Bladder Cancer by selecting all patients with primary CIS. The analysis covered gender, age, hospital type and hospital volume. Intravesical treatment and death due to bladder cancer were evaluated by multivariate logistic regression and multivariate Cox analysis, respectively. RESULTS The study included 1041 patients (median age at diagnosis 72 years) with a median follow-up of 65 months. Intravesical instillation therapy was given to 745 patients (72%), and 138 (13%) died from bladder cancer during the observation period. Male gender [odds ratio (OR) = 1.56, 95% confidence interval (CI) 1.13-2.17] and treatment at county (OR = 1.65, 95% CI 1.17-2.33), university (OR =2.12, 95% CI 1.48-3.03) or high-volume (OR = 1.92, 95% CI 1.34-2.75) hospitals were significantly associated with higher odds of intravesical instillations. The age category ≥80 years had a significantly lower chance of receiving intravesical therapy (OR = 0.44, 95% CI 0.26-0.74) and a significantly higher risk of dying from bladder cancer (hazard ratio = 3.03, 95% CI 1.71-5.35). CONCLUSION Significantly more frequent use of intravesical treatment of primary CIS was found for males and for patients treated at county, university and high-volume hospitals. Age ≥80 years was significantly related to less intravesical treatment and poorer cancer-specific survival.

Abstract
Objectives To evaluate the clinical practice of non-muscle invasive bladder cancer (NMIBC) treatment in Brazil in relation to international guidelines: Sociedade Brasileira de Urologia (SBU), European Association of Urology (EAU) and American Urological Association (AUA). Materials and Methods Cross-sectional study using questionnaires about urological practice on treatment of NMIBC during the 32nd Brazilian Congress of Urology. A total of 650 question forms were answered. Results There were 73% of complete answers (total of 476 question forms). In total, 246 urologists (51.68%) lived in the southeast region and 310 (65.13%) treat 1 to 3 cases of NMIBC per month. Low risk cancer: Only 35 urologists (7.5%) apply the single intravesical dose of immediate chemotherapy with Mitomicin C recommended by the above guidelines. Adjuvant therapy with BCG 2 to 4 weeks after TUR is used by 167 participants (35.1%) and 271 urologists (56.9%) use only TUR. High risk tumors: 397 urologists (83.4%) use adjuvant therapy, 375 (78.8%) use BCG 2 to 4 weeks after TUR, of which 306 (64.3%) referred the use for at least one year. Intravesical chemotherapy with Mitomicin C (a controversial recommendation) was used by 22 urologists (4.6%). BCG dose raised a lot of discrepancies. Induction doses of 40, 80 and 120mg were referred by 105 (22%), 193 (40.4%) and 54 (11.3%) respectively. Maintenance doses of 40, 80 and 120mg were referred by 190 (48.7%), 144 (37.0%) and 32 (8.2%) urologists, respectively. Schemes of administration were also varied and the one cited by SWOG protocol was the most used: 142 (29.8%). Conclusion SBU, EAU and AUA guidelines are partially respected by Brazilian urologists, particularly in low risk tumors. In high risk tumors, concordance rates are comparable to international data. Further studies are necessary to fully understand the reasons of such disagreement.

Abstract
Non-muscle-invasive bladder cancer (NMIBC) represents the vast majority of bladder cancer diagnoses, but this definition represents a spectrum of disease with a variable clinical course, notable for significant risk of recurrence and potential for progression. Management involves risk-adapted strategies of cystoscopic surveillance and intravesical therapy with the goal of bladder preservation when safe to do so. Multiple organizational guidelines exist to help practitioners manage this complicated disease process, but adherence to management principles among practising urologists is reportedly low. We review four major organizational guidelines on NMIBC: the American Urological Association (AUA)/Society of Urologic Oncology (SUO), European Association of Urology (EAU), National Comprehensive Cancer Network (NCCN), and National Institute for Health and Care Excellence (NICE) guidelines.

Abstract
Non-muscle-invasive bladder cancer (NMIBC) is categorized into high-risk and low-risk groups. Although, bacillus Calmette-Guerin (BCG) is the recommended adjuvant therapy of high-risk bladder tumor, optimal schedule (induction versus maintenance) of this therapy is a subject of debate. The objective was to evaluate outcomes of induction BCG in high-risk NMIBC patients at Shaukat Khanum Memorial Cancer Hospital & Research Centre, Pakistan and retrospective cohort study conducted in the department of urology, Shaukat Khanum Memorial Cancer Hospital & Research Centre, Pakistan. Three-year disease-free survival and progression-free survival was the main outcome measure. Data of 68 high-risk (Ta and T1 with G3 or high-grade subtype) bladder cancer patients who underwent transurethral resection followed by six-weekly intravesical BCG instillation was included in the study. Recurrence was described as biopsy-proven bladder cancer; whereas the presence of muscle invasion was considered as progression. Disease-free survival and progression-free survival were defined as time intervals elapsed between the starting date of BCG instillation and recurrence or progression, respectively. Kaplan-Meier curve was employed to estimate the three-year study end-points. Disease-free survival at three years was observed to be 66.2% and progression-free survival at 86.8%. The use of induction BCG alone for high-risk patients of NMIBC is a viable option both in terms of effective disease-free and progression-free survival rates.

Abstract
An unmet need exists for patients with high-risk non-muscle-invasive bladder cancer for whom bacille Calmette-Guérin (BCG) has failed and who seek further bladder-sparing approaches. This shortcoming poses difficult management dilemmas. This review explores previously investigated first-line intravesical therapies and discusses emerging second-line treatments for the heterogeneous group of patients for whom BCG has failed. The myriad of recently published and ongoing trials assessing novel salvage intravesical treatments offer promise to patients who both seek an effective cure and want to avoid radical surgery. However, these trials must carefully be contextualized by specific patient, tumor, and recurrence characteristics. As data continue to accumulate, there will potentially be a role for these agents as second-line or even first-line intravesical therapies. Cancer 2017;123:390-400. © 2016 American Cancer Society.

Abstract
Mitomycin C (MMC) intravesical therapy for "superficial" papillary bladder tumors was firstly introduced in the early seventies with promising results. In the following years, several pharmacokinetic studies investigated its mechanism of action to optimize the intravesical administration. Numerous studies confirmed thereafter both the ablative and the prophylactic efficacy and the low toxicity of MMC when intravesically given. In 1984, a complete response rate of 42% in 60 patients not responsive to thiotepa was reported with intravesical MMC at the dose of 40 mg diluted in 40 ml for 8 weeks. In the following decades, many large randomized studies showed the benefit of intravesical prophylaxis with MMC versus transurethral resection (TUR) alone. Since 2002, the role of adjuvant intravesical chemotherapy and of an early MMC instillation in preventing recurrence compared with TUR alone has been confirmed by large meta-analyses and stated by the European Association of Urology (EAU) guidelines. The need for further intravesical chemotherapy after the early instillation in patients at intermediate-high risk of recurrence has been proved by several trials. Although intravesical Bacillus Calmette-Guerìn (BCG) is considered the best choice for high-risk patients and MMC for the low-risk group, both MMC and BCG can be given to prevent recurrence in intermediate-risk patients. However, the higher efficacy of BCG over MMC is evident only if maintenance regimen is administered. Despite its proven efficacy, immediate intravesical MMC is not yet fully entered in common clinical practice and efforts should be made by the urologists to optimize its adoption.
