RESUMO
PURPOSE: To investigate the symptoms and delays in the clinical pathway of bladder cancer (BC). METHODS: This is a substudy of a prospective, randomized, multicenter phase III study (FinnBladder 9, NCT01675219) where the efficacy of photodynamic diagnosis and 6 weekly optimized mitomycin C instillations are studied in pTa bladder cancer with high risk for recurrence. The data of presenting symptoms and critical time points were prospectively collected, and the effect of factors on delays was analyzed. RESULTS: At the time of analysis, 245 patients were randomized. Analysis included 131 patients with primary bladder cancer and their complete data. Sixty-nine percent had smoking history and 67% presented with macroscopic hematuria. Median patient delay (from symptoms to health-care contact) was 7 days. The median general practice delay (from health-care contact to urology referral) was 8 days. Median time from urology referral to cystoscopy was 23 days and from cystoscopy to TUR-BT 21 days. Total time used in the clinical pathway (from symptom to TUR-BT) was 78 days. Current and former smokers had non-significantly shorter patient-related and general practice delays compared to never smokers. TUR-BT delay was significantly shorter in patients with malignant cytology (16 days) compared to patients with benign cytology (21 days, p = 0.03). CONCLUSIONS: Patient-derived delay was short and most of the delay occurred in the referral centers. The majority had macroscopic hematuria as the initial symptom. Surprisingly, current and past smokers were more prone to contact the health-care system compared to never smokers.

OBJECTIVE: Only a few studies with a long-term follow-up exist on patients with carcinoma in situ (CIS) treated with instillation therapy. The objective was to study the long-term outcome of patients with CIS after mitomycin C (MMC) monotherapy or alternating therapy with MMC and bacillus Calmette-Guérin (BCG). MATERIAL AND METHODS: The study population comprised 68 patients with CIS belonging to a larger material of 256 patients with non-muscle-invasive bladder carcinoma who were randomized between 1987 and 1992 in a prospective multicentre study. Patients received the same induction period with MMC and continued with maintenance treatment comprising either monthly instillations of MMC alone or alternating MMC and BCG instillations for up to 2 years. Primary endpoints were cancer-specific and overall mortality. Secondary endpoints were time to first recurrence and time to progression. The principal statistical methods were the Kaplan-Meier method and cumulative incidence analysis. RESULTS: The overall median follow-up time of the patients with CIS was 7.2 years and the median follow-up time of the patients still alive was 17.1 years. The non-stratified probability of dying from bladder carcinoma at 5, 10 and 15 years was 13%, 25% and 28%, respectively. No significant difference was found between the study groups with respect to time to first recurrence, progression, or disease-specific or overall mortality. CONCLUSIONS: The long-term bladder cancer-specific mortality was unexpectedly low despite the relatively ineffective instillation therapy and the poor outcome of the patients after progression.

BACKGROUND/AIM: Non-muscle invasive bladder carcinoma (NMIBC) is highly recurrent. We studied if 5-aminolevulinic acid (5-ALA) instillations before transurethral resection of bladder tumours (TURBT) and cystoscopy extend the time to recurrence during follow-up with NMIBC patients. PATIENTS AND METHODS: A prospective multicenter study enrolled 328 NMIBC patients. All TURBTs and control cystoscopies during the one-year study period were done with or without 5-ALA instillations. The primary endpoint was time to recurrence. The secondary endpoints were time to recurrence after 7.5, 10.5, and 13.5 months and the number of patients with progressive disease. RESULTS: The overall median follow-up time was 80.4 and 87.0 months for the control and study groups, respectively. There was no statistical difference in time to first recurrence between the two groups. CONCLUSION: We could not obtain significant differences between the control and 5-ALA groups in tumour recurrence among patients with NMIBC.

CONTEXT AND OBJECTIVE: To present the updated version of 2008 European Association of Urology (EAU) guidelines on non-muscle-invasive bladder cancer. EVIDENCE ACQUISITION: A systematic review of the recent literature on the diagnosis and treatment of non-muscle-invasive bladder cancer was performed. The guidelines were updated and the level of evidence and grade of recommendation were assigned. EVIDENCE SYNTHESIS: The diagnosis of bladder cancer depends on cystoscopy and histologic evaluation of the resected tissue. A complete and correct transurethral resection (TUR) is essential for the prognosis of the patient. When the initial resection is incomplete or when a high-grade or T1 tumour is detected, a second TUR within 2-6 wk should be performed. The short- and long-term risks of both recurrence and progression may be estimated for individual patients using the scoring system and risk tables. The stratification of patients to low, intermediate, and high-risk groups-separately for recurrence and progression-represents the cornerstone for indication of adjuvant treatment. In patients at low risk of tumour recurrence and progression, one immediate instillation of chemotherapy is strongly recommended. In those at an intermediate or high risk of recurrence and an intermediate risk of progression, one immediate instillation of chemotherapy should be followed by further instillations of chemotherapy or a minimum of 1 yr of bacillus Calmette-Guerin (BCG). In patients at high risk of tumour progression, after an immediate instillation of chemotherapy, intravesical BCG for at least 1 yr is indicated. Immediate cystectomy may be offered to the highest risk patients and in patients with BCG failure. The long version of the guidelines is available on www.uroweb.org. CONCLUSIONS: These EAU guidelines present the updated information about the diagnosis and treatment of non-muscle-invasive bladder cancer and offer the recent findings for the routine clinical application.

CONTEXT: The European Association of Urology (EAU) panel on Non-muscle-invasive Bladder Cancer (NMIBC) released an updated version of the guidelines on Non-muscle-invasive Bladder Cancer. OBJECTIVE: To present the 2016 EAU guidelines on NMIBC. EVIDENCE ACQUISITION: A broad and comprehensive scoping exercise covering all areas of the NMIBC guidelines published between April 1, 2014, and May 31, 2015, was performed. Databases covered by the search included Medline, Embase, and the Cochrane Libraries. Previous guidelines were updated, and levels of evidence and grades of recommendation were assigned. EVIDENCE SYNTHESIS: Tumours staged as TaT1 or carcinoma in situ (CIS) are grouped as NMIBC. Diagnosis depends on cystoscopy and histologic evaluation of the tissue obtained by transurethral resection of the bladder (TURB) in papillary tumours or by multiple bladder biopsies in CIS. In papillary lesions, a complete TURB is essential for the patient's prognosis. If the initial resection is incomplete, there is no muscle in the specimen, or a high-grade or T1 tumour is detected, a second TURB should be performed within 2-6 wk. The risks of both recurrence and progression may be estimated for individual patients using the European Organisation for Research and Treatment of Cancer (EORTC) scoring system and risk tables. The stratification of patients into low-, intermediate-, and high-risk groups is pivotal to recommending adjuvant treatment. For patients with a low-risk tumour and intermediate-risk patients at a lower risk of recurrence, one immediate instillation of chemotherapy is recommended. Patients with an intermediate-risk tumour should receive 1 yr of full-dose bacillus Calmette-Guérin (BCG) intravesical immunotherapy or instillations of chemotherapy for a maximum of 1 yr. In patients with high-risk tumours, full-dose intravesical BCG for 1-3 yr is indicated. In patients at highest risk of tumour progression, immediate radical cystectomy (RC) should be considered. RC is recommended in BCG-refractory tumours. The long version of the guidelines is available at the EAU Web site (www.uroweb.org/guidelines). CONCLUSIONS: These abridged EAU guidelines present updated information on the diagnosis and treatment of NMIBC for incorporation into clinical practice. PATIENT SUMMARY: The European Association of Urology has released updated guidelines on Non-muscle-invasive Bladder Cancer (NMIBC). Stratification of patients into low-, intermediate-, and high-risk groups is essential for decisions about adjuvant intravesical instillations. Risk tables can be used to estimate risks of recurrence and progression. Radical cystectomy should be considered only in case of failure of instillations or in NMIBC with the highest risk of progression.

OBJECTIVE: The aim of this study was to compare the long-term efficacy of BCG monotherapy to alternating therapy of mitomycin C (MMC) and BCG in patients with carcinoma in situ (CIS). MATERIALS AND METHODS: Between 1992 and 1997, 321 patients with CIS were randomized from Finland, Norway and Sweden in a prospective multicenter trial into two treatment groups. The alternating therapy comprised six weekly instillations of MMC 40â mg followed by 10 instillations of BCG (Connaught 120â mg) or MMC alternating monthly for 1 year. BCG monotherapy followed the same 6 + 10 schedule. Stratification was done by nationality and CIS category. Primary endpoints were time to first recurrence and time to progression. Secondary endpoints were disease-specific mortality and overall survival. The main statistical methods were the proportional subdistribution hazards model and Cox proportional hazards model with the cumulative incidence and Kaplan-Meier analyses. RESULTS: The median follow-up time was 9.9 years (maximum 19.9 years) in the BCG group and 8.9 years (maximum 20.3 years) in the alternating group. The risk of recurrence was significantly lower in the BCG group than in the alternating group (49 vs 59% at 15 years, respectively; hazard ratio 0.74, 95% confidence interval 0.54-1.00, p = 0.048). There were no significant differences in the other endpoints. Patients who progressed after 2 years were particularly prone to dying from bladder carcinoma. Younger patients performed worse than older ones. CONCLUSIONS: BCG monotherapy including monthly maintenance was effective and better than the alternating therapy. The risk of dying from bladder carcinoma after progression was high.

BACKGROUND: Patients with non-muscle-invasive bladder cancer (NMIBC) belonging to the intermediate-risk group should be treated with intravesical instillations to prevent recurrence and progression. OBJECTIVE: We compared the outcome of a monthly maintenance bacillus Calmette-Guérin (BCG) regimen with that of epirubicin (EPI) and interferon-α2a (IFN) in patients with NMIBC. DESIGN, SETTING, AND PARTICIPANTS: Our prospective randomized multicenter study comprised 229 eligible patients with frequently recurrent TaT1 grade 1-2 or low-grade NMIBC enrolled between 1997 and 2008. INTERVENTIONS: The four-arm study involved a single perioperative instillation of EPI plus five weekly instillations of BCG or EPI/IFN, followed by 11 monthly instillations in the 1-yr BCG or EPI/IFN maintenance arms, further followed by four additional quarterly instillations in the two 2-yr maintenance arms. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Time to recurrence, progression, disease-specific survival, and overall mortality were analyzed using the Kaplan-Meier and cumulative incidence analyses plus the Cox and proportional subdistribution hazards models. RESULTS AND LIMITATIONS: The median follow-up time was 7.5 and 7.4 yr in the BCG and EPI/IFN groups, respectively. The probability of recurrence was significantly lower in the BCG group than in the EPI/IFN group. The probability was 39% versus 72% at 7.4 yr, respectively (hazard ratio [HR]: 0.41; 95% confidence interval [CI], 0.28-0.60; p<0.001). There was no significant difference in the probability of progression or in overall survival. However, there was a significant difference in disease-specific mortality in favor of the BCG group (HR: 0.20; 95% CI, 0.04-0.91; p=0.04). CONCLUSIONS: The monthly maintenance BCG regimen showed excellent efficacy and was significantly better in preventing recurrence than a similar regimen of EPI/IFN-α2a. PATIENT SUMMARY: A monthly bacillus Calmette-Guérin (BCG) regimen showed excellent efficacy and was significantly better in preventing recurrence than a similar regimen of epirubicin and interferon-α2a. TRIAL REGISTRATION: Registration was not considered necessary at this stage of the follow-up because the study was initiated as early as in 1997, before the current requirements concerning study registrations were implemented.

CONTEXT: The European Association of Urology non-muscle-invasive bladder cancer (NMIBC) guidelines recommend that all low- and intermediate-risk patients receive a single immediate instillation of chemotherapy after transurethral resection of the bladder (TURB), but its use remains controversial. OBJECTIVE: To identify which NMIBC patients benefit from a single immediate instillation. EVIDENCE ACQUISITION: A systematic review and individual patient data (IPD) meta-analysis of randomized trials comparing the efficacy of a single instillation after TURB with TURB alone in NMIBC patients was carried out. EVIDENCE SYNTHESIS: A total of 13 eligible studies were identified. IPD were obtained for 11 studies randomizing 2278 eligible patients, 1161 to TURB and 1117 to a single instillation of epirubicin, mitomycin C, pirarubicin, or thiotepa. A total of 1128 recurrences, 108 progressions, and 460 deaths (59 due to bladder cancer [BCa]) occurred. A single instillation reduced the risk of recurrence by 35% (hazard ratio [HR]: 0.65; 95% confidence interval [CI], 0.58-0.74; p<0.001) and the 5-yr recurrence rate from 58.8% to 44.8%. The instillation did not reduce recurrences in patients with a prior recurrence rate of more than one recurrence per year or in patients with an European Organization for Research and Treatment of Cancer (EORTC) recurrence score ≥5. The instillation did not prolong either the time to progression or death from BCa, but it resulted in an increase in the overall risk of death (HR: 1.26; 95% CI, 1.05-1.51; p=0.015; 5-yr death rates 12.0% vs 11.2%), with the difference appearing in patients with an EORTC recurrence score ≥5. CONCLUSIONS: A single immediate instillation reduced the risk of recurrence, except in patients with a prior recurrence rate of more than one recurrence per year or an EORTC recurrence score ≥5. It does not prolong either time to progression or death from BCa. The instillation may be associated with an increase in the risk of death in patients at high risk of recurrence in whom the instillation is not effective or recommended. PATIENT SUMMARY: A single instillation of chemotherapy immediately after resection reduces the risk of recurrence in non-muscle-invasive bladder cancer; however, it should not be given to patients at high risk of recurrence due to its lack of efficacy in this subgroup.

CONTEXT: There is uncertainty regarding the oncologic effectiveness of kidney-sparing surgery (KSS) compared with radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC). OBJECTIVE: To systematically review the current literature comparing oncologic outcomes of KSS versus RNU for UTUC. EVIDENCE ACQUISITION: A computerised bibliographic search of the Medline, Embase, and Cochrane databases was performed for all studies reporting comparative oncologic outcomes of KSS versus RNU. Approaches considered for KSS were segmental ureterectomy (SU) and ureteroscopic (URS) or percutaneous (PC) management. Using the methodology recommended by the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines, we identified 22 nonrandomised comparative retrospective studies published between 1999 and 2015 that were eligible for inclusion in this systematic review. A narrative review and risk-of-bias (RoB) assessment were performed using cancer-specific survival (CSS) as the primary end point. EVIDENCE SYNTHESIS: Seven studies compared KSS overall (n=547) versus RNU (n=1376). Information on the comparison of SU (n=586) versus RNU (n=3692), URS (n=162) versus RNU (n=367), and PC (n=66) versus RNU (n=114) was available in 10, 5, and 2 studies, respectively. No significant difference was found between SU and RNU in terms of CSS or any other oncologic outcomes. Only patients with low-grade and noninvasive tumours experienced similar CSS after URS or PC when compared with RNU, despite an increased risk of local recurrence following endoscopic management of UTUC. The RoB assessment revealed, however, that the analyses were subject to a selection bias favouring KSS. CONCLUSIONS: Our systematic review suggests similar survival after KSS versus RNU only for low-grade and noninvasive UTUC when using URS or PC. However, selected patients with high-grade and invasive UTUC could safely benefit from SU when feasible. These results should be interpreted with caution due to the risk of selection bias. PATIENT SUMMARY: We reviewed the studies that compared kidney-sparing surgery versus radical nephroureterectomy for upper tract urothelial carcinoma. We found similar oncologic outcomes for favourable tumours when using ureteroscopic or percutaneous management, whereas indications for segmental ureterectomy could be extended to selected cases of aggressive tumours.

BACKGROUND: Recurrent TaT1 non-muscle-invasive bladder cancer (NMIBC) patients should be treated with immediate instillation of chemotherapy after transurethral resection of bladder tumour followed by instillation therapy. OBJECTIVE: To present long-term results of a study exploring the effect of initial mitomycin C (MMC) instillations followed by two types of immunotherapy for patients with frequently recurring NMIBC. DESIGN, SETTING, AND PARTICIPANTS: Between 1992 and 1996, 236 patients with frequently recurring TaT1 grade 1-2 NMIBC were enrolled in the prospective randomised multicentre FinnBladder-4 study. INTERVENTION: One perioperative plus four weekly instillations of MMC followed by monthly bacillus Calmette-Guérin (BCG) or alternating BCG and interferon (IFN)-α2b instillations for up to 1 yr. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Primary end points were time to first recurrence and time to progression. Secondary end points were disease-specific mortality and overall survival. The principal statistical methods were the proportional subdistribution hazards model and Cox proportional hazards model plus cumulative incidence and Kaplan-Meier analyses. RESULTS AND LIMITATIONS: The median follow-up was 10.3 yr (maximum: 19.8 yr) in the MMC-BCG group and 8.6 yr (maximum: 19.8 yr) in the MMC-BCG/IFN group. The probability of recurrence was significantly lower in the MMC-BCG group than in the MMC-BCG/IFN group (43% vs 78% at 10 yr and 45% vs 80% at 15 yr, respectively; hazard ratio: 2.86; 95% confidence interval, 1.98-4.13; p<0.001). There were no significant differences in the probability of progression, disease-free mortality, or overall survival. CONCLUSIONS: Perioperative plus four weekly MMC instillations followed by monthly BCG, instead of alternating BCG and IFN-α2b instillations, significantly reduce long-term recurrence. PATIENT SUMMARY: We demonstrated in non-muscle-invasive bladder cancer patients with exceptionally frequent recurrences that the risk of long-term recurrence was reduced from 78-80% to 43-45% if one perioperative plus four weekly mitomycin C instillations were followed by monthly bacillus Calmette-Guérin (BCG) instillations for 1 yr instead of alternating instillations of BCG and interferon-α2b. TRIAL REGISTRATION: The registration was not considered necessary at this stage of the follow-up because the study was initiated as early as in 1992 and the last randomisation took place in 1996, before the current requirements concerning study registrations were implemented.

CONTEXT: The European Association of Urology (EAU) guidelines panel on upper urinary tract urothelial cell carcinoma (UTUC) has prepared updated guidelines to aid clinicians in the current evidence-based management of UTUC and to incorporate recommendations into clinical practice. OBJECTIVE: To provide a brief overview of the EAU guidelines on UTUC as an aid to clinicians. EVIDENCE ACQUISITION: The recommendations provided in the current guidelines are based on a thorough review of available UTUC guidelines and articles identified following a systematic search of Medline. Data on urothelial malignancies and UTUC were searched using these keywords: urinary tract cancer; urothelial carcinomas; upper urinary tract, carcinoma; renal pelvis; ureter; bladder cancer; chemotherapy; nephroureterectomy; adjuvant treatment; instillation; neoadjuvant treatment; recurrence; risk factors; and survival. References were weighted by a panel of experts. EVIDENCE SYNTHESIS: Due to the rarity of UTUC, there are insufficient data to provide strong recommendations (ie, grade A). However, the results of recent multicentre studies are now available, and there is a growing interest in UTUC. The 2009 TNM classification is recommended. Recommendations are given for diagnosis and risk stratification as well as radical and conservative treatment, and prognostic factors are discussed. A single postoperative dose of intravesical mitomycin after nephroureterectomy reduces the risk of bladder tumour recurrence. Recommendations are also provided for patient follow-up after different therapeutic strategies. CONCLUSIONS: These guidelines contain information on the management of individual patients according to a current standardised approach. Urologists should take into account the specific clinical characteristics of each patient when determining the optimal treatment regimen, based on the proposed risk stratification of these tumours. PATIENT SUMMARY: Urothelial carcinoma of the upper urinary tract is rare, but because 60% of these tumours are invasive at diagnosis, an appropriate diagnosis is most important. A number of known risk factors exist.

CONTEXT: The European Association of Urology (EAU) guideline group for upper tract urothelial carcinoma (UTUC) has prepared updated guidelines to aid clinicians in assessing the current evidence-based management of UTUC and to incorporate present recommendations into daily clinical practice. OBJECTIVE: To provide a brief overview of the EAU guidelines on UTUC as an aid to clinicians in their daily clinical practice. EVIDENCE ACQUISITION: The recommendations provided in the current guidelines are based on a thorough review of available UTUC guidelines and articles identified using a systematic search of Medline. Data on urothelial malignancies and UTUCs in the literature were searched using Medline with the following keywords: urinary tract cancer; urothelial carcinomas; upper urinary tract, carcinoma; renal pelvis; ureter; bladder cancer; chemotherapy; nephroureterectomy; adjuvant treatment; instillation; neoadjuvant treatment; recurrence; risk factors; nomogram; and survival. References were weighted by a panel of experts. EVIDENCE SYNTHESIS: There is a lack of data in the current literature to provide strong recommendations (ie, grade A) due to the rarity of the disease. A number of recent multicentre studies are now available, and there is a growing interest in UTUC in the recent literature. Overall, 135 references have been included here, but most of these studies are still retrospective analyses. The TNM 2009 classification is recommended. Recommendations are given for diagnosis as well as radical and conservative treatment (ie, imperative and elective cases); additionally, prognostic factors are discussed. Recommendations are also provided for patient follow-up after different therapeutic options. CONCLUSIONS: These guidelines contain information for the management of individual patients according to a current standardised approach. Physicians must take into account the specific clinical characteristics of each individual patient when determining the optimal treatment regimen including tumour location, grade, and stage; renal function; molecular marker status; and medical comorbidities.

CONTEXT: The first European Association of Urology (EAU) guidelines on bladder cancer were published in 2002 [1]. Since then, the guidelines have been continuously updated. OBJECTIVE: To present the 2013 EAU guidelines on non-muscle-invasive bladder cancer (NMIBC). EVIDENCE ACQUISITION: Literature published between 2010 and 2012 on the diagnosis and treatment of NMIBC was systematically reviewed. Previous guidelines were updated, and the levels of evidence and grades of recommendation were assigned. EVIDENCE SYNTHESIS: Tumours staged as Ta, T1, or carcinoma in situ (CIS) are grouped as NMIBC. Diagnosis depends on cystoscopy and histologic evaluation of the tissue obtained by transurethral resection (TUR) in papillary tumours or by multiple bladder biopsies in CIS. In papillary lesions, a complete TUR is essential for the patient's prognosis. Where the initial resection is incomplete, where there is no muscle in the specimen, or where a high-grade or T1 tumour is detected, a second TUR should be performed within 2-6 wk. The risks of both recurrence and progression may be estimated for individual patients using the EORTC scoring system and risk tables. The stratification of patients into low-, intermediate-, and high-risk groups is pivotal to recommending adjuvant treatment. For patients with a low-risk tumour, one immediate instillation of chemotherapy is recommended. Patients with an intermediate-risk tumour should receive one immediate instillation of chemotherapy followed by 1 yr of full-dose bacillus Calmette-Guérin (BCG) intravesical immunotherapy or by further instillations of chemotherapy for a maximum of 1 yr. In patients with high-risk tumours, full-dose intravesical BCG for 1-3 yr is indicated. In patients at highest risk of tumour progression, immediate radical cystectomy should be considered. Cystectomy is recommended in BCG-refractory tumours. The long version of the guidelines is available from the EAU Web site: http://www.uroweb.org/guidelines/. CONCLUSIONS: These abridged EAU guidelines present updated information on the diagnosis and treatment of NMIBC for incorporation into clinical practice. PATIENT SUMMARY: The EAU Panel on Non-muscle Invasive Bladder Cancer released an updated version of their guidelines. Current clinical studies support patient selection into different risk groups; low, intermediate and high risk. These risk groups indicate the likelihood of the development of a new (recurrent) cancer after initial treatment (endoscopic resection) or progression to more aggressive (muscle-invasive) bladder cancer and are most important for the decision to provide chemo- or immunotherapy (bladder installations). Surgical removal of the bladder (radical cystectomy) should only be considered in patients who have failed chemo- or immunotherapy, or who are in the highest risk group for progression.

CONTEXT: The European Association of Urology (EAU) Guideline Group for urothelial cell carcinoma of the upper urinary tract (UUT-UCC) has prepared new guidelines to aid clinicians in assessing the current evidence-based management of UUT-UCC and to incorporate present recommendations into daily clinical practice. OBJECTIVE: This paper provides a brief overview of the EAU guidelines on UUT-UCC as an aid to clinicians in their daily practice. EVIDENCE ACQUISITION: The recommendations provided in the current guidelines are based on a thorough review of available UUT-UCC guidelines and papers identified using a systematic search of Medline. Data on urothelial malignancies and UUT-UCCs in the literature were searched using Medline with the following keywords: urinary tract cancer, urothelial carcinomas, upper urinary tract, carcinoma, transitional cell, renal pelvis, ureter, bladder cancer, chemotherapy, nephroureterectomy, adjuvant treatment, neoadjuvant treatment, recurrence, risk factors, and survival. A panel of experts weighted the references. EVIDENCE SYNTHESIS: There is a lack of data in the current literature to provide strong recommendations due to the rarity of the disease. A number of recent multicentre studies are now available, whereas earlier publications were based only on limited populations. However, most of these studies have been retrospective analyses. The TNM classification 2009 is recommended. Recommendations are given for diagnosis as well as for radical and conservative treatment; prognostic factors are also discussed. Recommendations are provided for patient follow-up after different therapeutic options. CONCLUSIONS: These guidelines contain information for the diagnosis and treatment of individual patients according to a current standardised approach. When determining the optimal treatment regimen, physicians must take into account each individual patient's specific clinical characteristics with regard to renal function including medical comorbidities; tumour location, grade and stage; and molecular marker status.

CONTEXT AND OBJECTIVE: To present the 2011 European Association of Urology (EAU) guidelines on non-muscle-invasive bladder cancer (NMIBC). EVIDENCE ACQUISITION: Literature published between 2004 and 2010 on the diagnosis and treatment of NMIBC was systematically reviewed. Previous guidelines were updated, and the level of evidence (LE) and grade of recommendation (GR) were assigned. EVIDENCE SYNTHESIS: Tumours staged as Ta, T1, or carcinoma in situ (CIS) are grouped as NMIBC. Diagnosis depends on cystoscopy and histologic evaluation of the tissue obtained by transurethral resection (TUR) in papillary tumours or by multiple bladder biopsies in CIS. In papillary lesions, a complete TUR is essential for the patient's prognosis. Where the initial resection is incomplete or where a high-grade or T1 tumour is detected, a second TUR should be performed within 2-6 wk. In papillary tumours, the risks of both recurrence and progression may be estimated for individual patients using the scoring system and risk tables. The stratification of patients into low-, intermediate-, and high-risk groups-separately for recurrence and progression-is pivotal to recommending adjuvant treatment. For patients with a low risk of tumour recurrence and progression, one immediate instillation of chemotherapy is recommended. Patients with an intermediate or high risk of recurrence and an intermediate risk of progression should receive one immediate instillation of chemotherapy followed by a minimum of 1 yr of bacillus Calmette-Guérin (BCG) intravesical immunotherapy or further instillations of chemotherapy. Papillary tumours with a high risk of progression and CIS should receive intravesical BCG for 1 yr. Cystectomy may be offered to the highest risk patients, and it is at least recommended in BCG failure patients. The long version of the guidelines is available from the EAU Web site (www.uroweb.org). CONCLUSIONS: These abridged EAU guidelines present updated information on the diagnosis and treatment of NMIBC for incorporation into clinical practice.

BACKGROUND: The long-term prospective data on bacillus Calmette-Guérin (BCG) and mitomycin C (MMC) instillation therapy are limited. OBJECTIVE: To compare the long-term benefit of BCG and MMC maintenance therapy in patients with recurrent bladder carcinoma. DESIGN, SETTING, AND PARTICIPANTS: Eighty-nine patients with frequently recurrent TaT1 disease without carcinoma in situ (CIS) were eligible. Originally, the patients were enrolled in the prospective FinnBladder I study between 1984 and 1987 and randomised to receive BCG or MMC. Both regimens involved five weekly instillations, followed by monthly instillations for 2 yr. Because of alkalinising the urine and adjusting the dose to bladder capacity, the average concentration of MMC was low: 30-40 mg in 150-200 ml of phosphate buffer. Overall median follow-up time was 8.5 yr, whereas the median follow-up time of the patients who were still alive was 19.4 yr. MEASUREMENTS: Primary end points were time to first recurrence and overall mortality. Secondary end points were progression and disease-specific mortality. RESULTS AND LIMITATIONS: Thirty-six of 45 patients (80.0%) in the MMC group experienced recurrence in contrast to 26 of 44 patients (59.1%) in the BCG group. This finding was reflected in significantly lower cumulative incidence estimates in the BCG group (p=0.005). There was a weak trend for fewer progressions (p=0.1) and cancer-specific deaths (p=0.2) in the cumulative incidence analysis, as 4 patients versus 10 patients progressed and 4 patients versus 9 patients died from the disease in the BCG group versus the MMC group, respectively. No difference existed in the overall mortality. The study population, however, was too small for conclusive evidence about progression or survival. CONCLUSIONS: An intensive intravesical BCG immunotherapy results in a sustained and significant long-term reduction in recurrence in frequently recurrent bladder carcinoma. The relatively low progression rate during the long follow-up suggests that it may be difficult to show significant differences in overall mortality with a substantially larger but otherwise similar study population. TRIAL REGISTRATION: Registration was not considered to be necessary at this stage of the follow-up because the study was initiated as early as 1984 and the last randomisation took place in July 1987, that is, long before the current requirements concerning study registrations were implemented.

CONTEXT AND OBJECTIVE: To present the updated version of 2008 European Association of Urology (EAU) guidelines on non-muscle-invasive bladder cancer. EVIDENCE ACQUISITION: A systematic review of the recent literature on the diagnosis and treatment of non-muscle-invasive bladder cancer was performed. The guidelines were updated and the level of evidence and grade of recommendation were assigned. EVIDENCE SYNTHESIS: The diagnosis of bladder cancer depends on cystoscopy and histologic evaluation of the resected tissue. A complete and correct transurethral resection (TUR) is essential for the prognosis of the patient. When the initial resection is incomplete or when a high-grade or T1 tumour is detected, a second TUR within 2-6 wk should be performed. The short- and long-term risks of both recurrence and progression may be estimated for individual patients using the scoring system and risk tables. The stratification of patients to low, intermediate, and high-risk groups-separately for recurrence and progression-represents the cornerstone for indication of adjuvant treatment. In patients at low risk of tumour recurrence and progression, one immediate instillation of chemotherapy is strongly recommended. In those at an intermediate or high risk of recurrence and an intermediate risk of progression, one immediate instillation of chemotherapy should be followed by further instillations of chemotherapy or a minimum of 1 yr of bacillus Calmette-Guerin (BCG). In patients at high risk of tumour progression, after an immediate instillation of chemotherapy, intravesical BCG for at least 1 yr is indicated. Immediate cystectomy may be offered to the highest risk patients and in patients with BCG failure. The long version of the guidelines is available on www.uroweb.org. CONCLUSIONS: These EAU guidelines present the updated information about the diagnosis and treatment of non-muscle-invasive bladder cancer and offer the recent findings for the routine clinical application.

PURPOSE: We studied the cytolytic mechanism of nonstimulated, bacillus Calmette-Guerin (BCG) stimulated and interleukin (IL)-2 (Chiron Corp., Amsterdam, The Netherlands) stimulated peripheral blood mononuclear cells. MATERIALS AND METHODS: We inhibited the cytotoxicity of nonstimulated, BCG stimulated and IL-2 stimulated peripheral blood mononuclear cells against various target cells using 3 monoclonal antibodies directed against the CD16 receptor of natural killer cells or alternatively monoclonal antibodies against the alpha and beta subunits of the IL-2 receptor complex (IL-2R). The main target cell was the poorly differentiated transitional cell line T24. RESULTS: Of the 3 anti-CD16 antibodies tested only CLB FcR-gran/1 effectively inhibited natural, IL-2 stimulated and BCG enhanced cytotoxicity. Cytotoxicity was also markedly diminished after depletion of CD16+CD56+/- cells with CLB FcR-gran/1. An hour of pretreatment with CLB FcR-gran/1 was enough to reduce significantly the level of cytotoxicity evoked by overnight stimulation with BCG or IL-2. Simultaneous administration of anti-IL-2Ralpha and anti-IL-2Rbeta significantly decreased the killing of target cells by BCG stimulated and IL-2 stimulated peripheral blood mononuclear cells. CONCLUSIONS: Within the stimulation times chosen the same killing mechanisms seemed to explain the nonstimulated, BCG stimulated and IL-2 stimulated cytotoxicity with CD16 positive cells as central effectors. Anti-CD16 antibodies may deliver a target cell independent down-regulatory signal to natural killer cells or alternatively mimic a nonIg ligand and block the detection of the target cell.
