Protocol of the Italian Radical Cystectomy Registry (RIC): a non-randomized, 24-month, multicenter study comparing robotic-assisted, laparoscopic, and open surgery for radical cystectomy in bladder cancer.

BACKGROUND: Bladder cancer is the ninth most common type of cancer worldwide. In the past, radical cystectomy via open surgery has been considered the gold-standard treatment for muscle invasive bladder cancer. However, in recent years there has been a progressive increase in the use of robot-assisted laparoscopic radical cystectomy. The aim of the current project is to investigate the surgical, oncological, and functional outcomes of patients with bladder cancer who undergo radical cystectomy comparing three different surgical techniques (robotic-assisted, laparoscopic, and open surgery). Pre-, peri- and post-operative factors will be examined, and participants will be followed for a period of up to 24 months to identify risks of mortality, oncological outcomes, hospital readmission, sexual performance, and continence. METHODS: We describe a protocol for an observational, prospective, multicenter, cohort study to assess patients affected by bladder neoplasms undergoing radical cystectomy and urinary diversion. The Italian Radical Cystectomy Registry is an electronic registry to prospectively collect the data of patients undergoing radical cystectomy conducted with any technique (open, laparoscopic, robotic-assisted). Twenty-eight urology departments across Italy will provide data for the study, with the recruitment phase between 1st January 2017-31st October 2020. Information is collected from the patients at the moment of surgical intervention and during follow-up (3, 6, 12, and 24 months after radical cystectomy). Peri-operative variables include surgery time, type of urinary diversion, conversion to open surgery, bleeding, nerve sparing and lymphadenectomy. Follow-up data collection includes histological information (e.g., post-op staging, grading, and tumor histology), short- and long-term outcomes (e.g., mortality, post-op complications, hospital readmission, sexual potency, continence etc). DISCUSSION: The current protocol aims to contribute additional data to the field concerning the short- and long-term outcomes of three different radical cystectomy surgical techniques for patients with bladder cancer, including open, laparoscopic, and robot-assisted. This is a comparative-effectiveness trial that takes into account a complex range of factors and decision making by both physicians and patients that affect their choice of surgical technique.

Risk-adapted management of low-grade bladder tumours: recommendations from the International Bladder Cancer Group (IBCG).

OBJECTIVE: To provide a contemporary update and recommendations for the diagnosis and management of low-grade non-muscle-invasive bladder cancer (BCa) based on current literature and expert consensus of the International Bladder Cancer Group. METHODS: We reviewed published trials, guidelines, meta-analyses and reviews (up to March 2019) and provide recommendations on baseline evaluations, treatment, endpoints, study design and surveillance protocols. RESULTS: Low-grade Ta BCa poses minimal risk to patients in terms of progression and disease-specific survival. Thus, to minimize patient morbidity, this entity should be managed appropriately. After initial diagnosis of low-grade Ta tumour, subsequent stable, low-grade-appearing recurrences can be managed conservatively with office cystoscopy and fulguration or even followed using an active surveillance protocol. Intravesical therapy other than single-dose peri-operative chemotherapy instillation should be used judiciously, and only after assigning appropriate risk points. Routine use of urinary cytology - other than at initial risk stratification, or for patients on active surveillance without therapy - is not recommended; and surveillance cystoscopy may be discontinued after 5 years. Clinical studies in this group of patients should focus on recurrence rates, and time to recurrence, rather than progression events. CONCLUSIONS: The International Bladder Cancer Group has developed formal recommendations regarding the diagnosis, treatment and surveillance of low-grade non-muscle-invasive BCa to minimize morbidity and encourage uniformity among studies in this disease.

Complication rate after cystectomy following pelvic radiotherapy: an international, multicenter, retrospective series of 682 cases.

PURPOSE: Conflicting evidence exists on the complication rates after cystectomy following previous radiation (pRTC) with only a few available series. We aim to assess the complication rate of pRTC for abdominal-pelvic malignancies. METHODS: Patients treated with radical cystectomy following any previous history of RT and with available information on complications for a minimum of 1 year were included. Univariable and multivariable logistic regression models were used to assess the relationship between the variable parameters and the risk of any complication. RESULTS: 682 patients underwent pRTC after a previous RT (80.5% EBRT) for prostate, bladder (BC), gynecological or other cancers in 49.1%, 27.4%, 9.8% and 12.9%, respectively. Overall, 512 (75.1%) had at least one post-surgical complication, classified as Clavien ≥ 3 in 29.6% and Clavien V in 2.9%. At least one surgical complication occurred in 350 (51.3%), including bowel leakage in 6.2% and ureteric stricture in 9.4%. A medical complication was observed in 359 (52.6%) patients, with UTI/pyelonephritis being the most common (19%), followed by renal failure (12%). The majority of patients (86%) received an incontinent urinary diversion. In multivariable analysis adjusted for age, gender and type of RT, patients treated with RT for bladder cancer had a 1.7 times increased relative risk of experiencing any complication after RC compared to those with RT for prostate cancer (p = 0.023). The type of diversion (continent vs non-continent) did not influence the risk of complications. CONCLUSION: pRTC carries a high rate of major complications that dramatically exceeds the rates reported in RT-naïve RCs.

Epidemiology, prevention, screening, diagnosis, and evaluation: update of the ICUD-SIU joint consultation on bladder cancer.

PURPOSE: To update current recommendations on prevention, screening, diagnosis, and evaluation of bladder cancer (BC) based on a thorough assessment of the most recent literature on these topics. METHODS: A non-systematic review was performed, including articles until June 2017. A variety of original articles, reviews, and editorials were selected according to their epidemiologic, demographic, and clinical relevance. Assessment of the level of evidence and grade of recommendations was performed according to the International Consultation on Urological Diseases grading system. RESULTS: BC is the ninth most common cancer worldwide with 430,000 new cases in 2012. Currently, approximately 165,000 people die from the disease annually. Absolute incidence and prevalence of BC are expected to rise significantly during the next decades because of population ageing. Tobacco smoking is still the main risk factor, accounting for about 50% of cases. Smoking cessation is, therefore, the most relevant recommendation in terms of prevention, as the risk of developing BC drops almost 40% within 5 years of cessation. BC screening is not recommended for the general population. BC diagnosis remains mainly based on cystoscopy, but development of new endoscopic and imaging technologies may rapidly change the diagnosis algorithm. The same applies for local, regional, and distant staging modalities. CONCLUSIONS: A thorough understanding of epidemiology, risk factors, early detection strategies, diagnosis, and evaluation is essential for correct, evidence-based management of BC patients. Recent developments in endoscopic techniques and imaging raise the hope for providing better risk-adopted approaches and thereby improving clinical outcomes.

Upper Urinary Tract Carcinoma In Situ: Current Knowledge, Future Direction.

PURPOSE: Carcinoma in situ of the urinary tract is a high grade form of nonmuscle invasive urothelial cancer. Our understanding of this entity in the upper tract is poor, and case management remains challenging due to knowledge gaps regarding the definition, diagnosis, treatment options and followup of the disease. We reviewed the available literature for similarities and differences between bladder and upper tract carcinoma in situ, and herein summarize the best available data. MATERIALS AND METHODS: We reviewed PubMed® and MEDLINE™ databases from January 1976 through September 2014. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement was used to screen publications. All authors participated in the development of a consensus definition of disease. RESULTS: A total of 61 publications were found suitable for this review. All studies were retrospective. Compared to bladder carcinoma in situ, upper tract carcinoma in situ appears to have lower progression rates and improved survival. All available studies demonstrate topical therapy to be effective in treating upper tract carcinoma in situ, with decreased recurrence rates compared to bladder carcinoma in situ. Highlighted areas of current knowledge gaps include variable definitions of disease, methods of drug delivery and ideal treatment course. Improving methods for detection may allow easier diagnosis and more effective treatment. CONCLUSIONS: Based on the available data, organ preserving therapy with topical agents is an alternative to radical surgery in select patients with upper tract carcinoma in situ, although this method has not been evaluated in prospective trials. A paradigm shift regarding detection and treatment is needed to improve care and allow better renal preservation. A consensus definition of the disease is offered, and several areas of major knowledge gaps and opportunities for future research are identified.

Cytoreductive nephrectomy in patients with metastatic renal cell carcinoma in the era of targeted therapy: a bibliographic review.

PURPOSE: To evaluate the role of cytoreductive nephrectomy (CN) in metastatic renal cell carcinoma (mRCC), against a background of lack of evidence following the introduction of targeted therapy. METHODS: A literature review was performed in January 2017 using the MEDLINE/PubMed and EMBASE databases. The PRISMA guidelines were followed for conduct of the study. Two authors independently screened the 270 papers retrieved from the search, and the finally selected publications were identified by consensus between the two reviewers. A total of 55 studies were included in the present review. RESULTS: Globally, the indications for CN have decreased over recent years. Although current guidelines consider CN an adequate option in selected patients based on prospective studies in the cytokine era, evidence for CN in the era of targeted therapy is based on retrospective studies only. CONCLUSIONS: The results of ongoing prospective studies are still awaited. Retrospective data suggest that young male patients with oligometastatic disease and a good performance status can be considered suitable surgical candidates who may benefit from CN.

Increasing age is not associated with toxicity leading to discontinuation of treatment in patients with urothelial non-muscle-invasive bladder cancer randomised to receive 3 years of maintenance bacille Calmette-Guérin: results from European Organisation for Research and Treatment of Cancer Genito-Urinary Group study 30911.

OBJECTIVE: To determine the relationship of age to side-effects leading to discontinuation of treatment in patients with stage Ta-T1 non-muscle-invasive bladder cancer (NMIBC) treated with maintenance bacille Calmette-Guérin (BCG). PATIENTS AND METHODS: We evaluated toxicity for 487 eligible patients with intermediate- or high-risk Ta-T1 (without carcinoma in situ) NMIBC randomised to receive 3 years of maintenance BCG therapy (247 BCG alone and 240 BCG + isoniazid) in European Organisation for Research and Treatment of Cancer Genito-Urinary Group trial 30911. The percentage of patients who stopped for toxicity and the number of treatment cycles that they received were compared in four age groups, ≤60, 61-70, 71-75 and >75 years, using the Mantel-Haenszel chi-square test for trend. RESULTS: The percentage of patients stopping BCG for toxicity was 17.9% in patients aged ≤60 years, 21.9% in patients aged 61-70 years, 22.9% in patients aged 71-75 years, and 16.4% in patients aged >75 years (P = 0.90). For both systemic and local side-effects, there was likewise no significant difference. CONCLUSION: In patients with intermediate- and high-risk Ta-T1 NMIBC treated with BCG, no differences in toxicity as a reason for stopping treatment were detected based on patient age.

Patterns of prescription and adherence to European Association of Urology guidelines on androgen deprivation therapy in prostate cancer: an Italian multicentre cross-sectional analysis from the Choosing Treatment for Prostate Cancer (CHOICE) study.

OBJECTIVE: To evaluate both the patterns of prescription of androgen deprivation therapy (ADT) in patients with prostate cancer (PCa) and the adherence to European Association of Urology (EAU) guidelines for ADT prescription. METHODS: The Choosing Treatment for Prostate Cancer (CHOICE) study was an Italian multicentre cross-sectional study conducted between December 2010 and January 2012. A total of 1 386 patients, treated with ADT for PCa (first prescription or renewal of ADT), were selected. With regard to the EAU guidelines on ADT, the cohort was categorized into discordant ADT (Group A) and concordant ADT (Group B). RESULTS: The final cohort included 1 075 patients with a geographical distribution including North Italy (n = 627, 58.3%), Central Italy (n = 233, 21.7%) and South Italy (n = 215, 20.0%). In the category of patients treated with primary ADT, a total of 125 patients (56.3%) were classified as low risk according to D'Amico classification. With regard to the EAU guidelines, 285 (26.51%) and 790 patients (73.49%) were classified as discordant (Group A) and concordant (Group B), respectively. In Group A, patients were more likely to receive primary ADT (57.5%, 164/285 patients) than radical prostatectomy (RP; 30.9%, 88/285 patients), radiation therapy (RT; 6.7%, 19/285 patients) or RP + RT (17.7%, 14/285 patients; P < 0.01). Multivariate logistic regression analysis, adjusted for clinical and pathological variables, showed that patients from Central Italy (odds ratio [OR] 2.86; P < 0.05) and South Italy (OR 2.65; P < 0.05) were more likely to receive discordant ADT. CONCLUSION: EAU guideline adherence for ADT was low in Italy and was influenced by geographic area. Healthcare providers and urologists should consider these results in order to quantify the inadequate use of ADT and to set policy strategies to overcome this risk.

Defining progression in nonmuscle invasive bladder cancer: it is time for a new, standard definition.

PURPOSE: Despite being one of the most important clinical outcomes in nonmuscle invasive bladder cancer, there is currently no standard definition of disease progression. Major clinical trials and meta-analyses have used varying definitions or have failed to define this end point altogether. A standard definition of nonmuscle invasive bladder cancer progression as determined by reproducible and reliable procedures is needed. We examine current definitions of nonmuscle invasive bladder cancer progression, and propose a new definition that will be more clinically useful in determining patient prognosis and comparing treatment options. MATERIALS AND METHODS: The IBCG (International Bladder Cancer Group) analyzed published clinical trials and meta-analyses that examined nonmuscle invasive bladder cancer progression as of December 2012. The limitations of the definitions of progression used in these trials were considered, as were additional parameters associated with the advancement of nonmuscle invasive bladder cancer. RESULTS: The most commonly used definition of nonmuscle invasive bladder cancer progression is an increase in stage from nonmuscle invasive to muscle invasive disease. Although this definition is clinically important, it fails to include other important parameters of advancing disease such as progression to lamina propria invasion and increase in grade. CONCLUSIONS: The IBCG proposes the definition of nonmuscle invasive bladder cancer progression as an increase in T stage from CIS or Ta to T1 (lamina propria invasion), development of T2 or greater or lymph node (N+) disease or distant metastasis (M1), or an increase in grade from low to high. Investigators should consider the use of this new definition to help standardize protocols and improve the reporting of progression.

Defining and treating the spectrum of intermediate risk nonmuscle invasive bladder cancer.

PURPOSE: Low, intermediate and high risk categories have been defined to help guide the treatment of patients with nonmuscle invasive bladder cancer (Ta, T1, CIS). However, while low and high risk disease has been well classified, the intermediate risk category has traditionally comprised a heterogeneous group that does not fit into either of these categories. As a result, many urologists remain uncertain about the categorization of patients as intermediate risk as well as the selection of the most appropriate therapeutic option for this patient population. We review the current literature and clinical practice guidelines on intermediate risk nonmuscle invasive bladder cancer and, based on our findings, provide urologists with a better understanding of this heterogeneous risk group as well as practical recommendations for the treatment of intermediate risk patients. MATERIALS AND METHODS: The IBCG analyzed published clinical trials, meta-analyses and current clinical practice guidelines on intermediate risk nonmuscle invasive bladder cancer available as of September 2013. The definitions of intermediate risk, patient outcomes and guideline recommendations were considered, as were the limitations of the available literature and additional parameters that may be useful in guiding treatment decisions in intermediate risk patients. RESULTS: Current definitions and management recommendations for intermediate risk nonmuscle invasive bladder cancer vary. The most simple and practical definition is that proposed by the IBCG and the AUA of multiple and/or recurrent low grade Ta tumors. The IBCG suggests that several factors should be considered in clinical decisions in intermediate risk disease, including number (greater than 1) and size (greater than 3 cm) of tumors, timing (recurrence within 1 year) and frequency (more than 1 per year) of recurrence, and previous treatment. In patients without these risk factors a single, immediate instillation of chemotherapy is advised. In those with 1 to 2 risk factors adjuvant intravesical therapy (intravesical chemotherapy or maintenance bacillus Calmette-Guérin) is recommended, and previous intravesical therapy should be considered when choosing between these adjuvant therapies. For those patients with 3 to 4 risk factors, maintenance bacillus Calmette-Guérin is recommended. It is also important that all intermediate risk patients are accurately risk stratified at initial diagnosis and during subsequent followup. This requires appropriate transurethral resection of the bladder tumor, vigilance to rule out carcinoma in situ or other potential high risk tumors, and review of histological material directly with the pathologist. CONCLUSIONS: Intermediate risk disease is a heterogeneous category, and there is a paucity of independent studies comparing therapies and outcomes in subgroups of intermediate risk patients. The IBCG has proposed a management algorithm that considers tumor characteristics, timing and frequency of recurrence, and previous treatment. Subgroup analyses of intermediate risk subjects in pivotal EORTC trials and meta-analyses will be important to validate the proposed algorithm and support clear evidence-based recommendations for subgroups of intermediate risk patients.

Role of multiparametric magnetic resonance imaging (MRI) in focal therapy for prostate cancer: a Delphi consensus project.

OBJECTIVE: To define the role of multiparametric MRI (mpMRI) for treatment planning, guidance and follow-up in focal therapy for prostate cancer based on a multidisciplinary Delphi consensus project. MATERIALS AND METHODS: An online consensus process based on a questionnaire was circulated according to the Delphi method. Discussion points were identified by literature research and were sent to the panel via an online questionnaire in three rounds. A face-to-face consensus meeting followed the three rounds of questions that were sent to a 48-participant expert panel consisting of urologists, radiologists and engineers. Participants were presented with the results of the previous rounds. Conclusions formulated from the results of the questionnaire were discussed in the final face-to-face meeting. RESULTS: Consensus was reached in 41% of all key items. Patients selected for focal therapy should have biopsy-proven prostate cancer. Biopsies should ideally be performed after mpMRI of the prostate. Standardization of imaging protocols is essential and mpMRIs should be read by an experienced radiologist. In the follow-up after focal therapy, mpMRI should be performed after 6 months, followed by a yearly mpMRI. mpMRI findings should be confirmed by targeted biopsies before re-treatment. No consensus was reached on whether mpMRI could replace transperineal template saturation biopsies to exclude significant lesions outside the target lesion. CONCLUSIONS: Consensus was reached on a number of areas related to the conduct, interpretation and reporting of mpMRI for use in treatment planning, guidance and follow-up of focal therapy for prostate cancer. Future studies, comparing mpMRI with transperineal saturation mapping biopsies, will confirm the importance of mpMRI for a variety of purposes in focal therapy for prostate cancer.

Optimizing the Use of Next-Generation Sequencing Assays in Patients With Urothelial Carcinoma: Recommendations by the 2023 San Raffaele Retreat Panel.

BACKGROUND: The application of precision medicine in clinical practice implies a thorough evaluation of actionable genomic alterations to streamline therapeutic decision making. Comprehensive genomic profiling of tumor via next-generation sequencing (NGS) represents a great opportunity but also several challenges. During the 2023 San Raffaele Retreat, we aimed to provide expert recommendations for the optimal use of NGS in urothelial carcinoma (UC). MATERIALS AND METHODS: A modified Delphi method was utilized, involving a panel of 12 experts in UC from European and United States centers, including oncologists, urologists, pathologists, and translational scientists. An initial survey, conducted before the meeting, delivered 15 statements to the panel. A consensus was defined when ≥70% agreement was reached for each statement. Statements not meeting the consensus threshold were discussed during the meeting. RESULTS: Nine of the 15 statements covering patient selection, cancer characteristics, and type of NGS assay, achieved a consensus during the survey. The remaining six statements addressing the optimal timing of NGS use, the ideal source of tumor biospecimen for NGS testing, and the subsequent need to evaluate the germline nature of certain genomic findings were discussed during the meeting, leading to unanimous agreement at the end of the conference. CONCLUSION: This consensus-building effort addressed multiple unanswered questions regarding the use of NGS in UC. The opinion of experts was in favor of broader use of NGS. In a setting where recommendations/guidelines may be limited, these insights may aid clinicians to provide informed counselling and raise the bar of precision and personalized therapy.

Current clinical practice gaps in the treatment of intermediate- and high-risk non-muscle-invasive bladder cancer (NMIBC) with emphasis on the use of bacillus Calmette-Guérin (BCG): results of an international individual patient data survey (IPDS).

OBJECTIVES: To examine the management of intermediate- and high-risk non-muscle-invasive bladder cancer (NMIBC), particularly with regard to the use of bacillus Calmette-Guérin (BCG) therapy, in North America and Europe. To compare NMIBC management practices to European Association of Urology (EAU) and American Urological Association (AUA) guideline recommendations for the management of intermediate- and high-risk NMIBC. PATIENTS AND METHODS: In all, 102 urologists from Europe and North America participated in this retrospective on-line chart review, which was conducted between 1 April 2011 and 30 April 2012. Participants selected the charts of the first 10 intermediate- (defined as multiple or recurrent low-grade tumours) or high-risk (defined as any T1 and/or high-grade/G3 tumours and/or carcinoma in situ) patients who underwent transurethral resection of bladder tumour in 2009. Physicians retrospectively reviewed the charts and completed an on-line survey consisting of questions related to diagnosis, planned treatment, treatment status and follow-up. In all, 971 patients (197 intermediate-risk; 774 high-risk) were included in the analysis; frequency counts and associated percentages were used to analyse treatment variables. RESULTS: In all, 47% of intermediate-risk patients received EAU or AUA guideline-recommended intravesical therapy: intravesical chemotherapy, BCG induction therapy or BCG induction plus maintenance. Of the high-risk patients, 50% received maintenance BCG as recommended by the EAU and the AUA; although not recommended for high-risk NMIBC, 12.5% received intravesical chemotherapy. Of patients prescribed maintenance BCG, 93% were scheduled for at least 1 year of therapy. Notably, only 15% discontinued BCG maintenance and, of these discontinuations, 65% were due to reasons unrelated to BCG-associated adverse events. CONCLUSIONS: There is significant non-adherence to EAU and AUA guideline recommendations for BCG use in intermediate- and high-risk NMIBC. However, most of those patients prescribed BCG maintenance therapy are scheduled for at least 1 year of therapy, as recommended by current guidelines for NMIBC management, and BCG maintenance discontinuation is low.

International Bladder Cancer Group Consensus Statement on Clinical Trial Design for Patients with Bacillus Calmette-Guérin-exposed High-risk Non-muscle-invasive Bladder Cancer.

CONTEXT: A large proportion of patients with non-muscle-invasive bladder cancer (NMIBC) fall in the gap between bacillus Calmette-Guérin (BCG)-naïve and BCG-unresponsive disease. As multiple therapeutic agents move into this gray area, there is a critical need to define the disease state and establish recommendations for optimal trial design. OBJECTIVE: To develop a consensus on optimal trial design for patients with BCG-exposed NMIBC, defined as high-grade recurrence after BCG treatment that does not meet the criteria for BCG-unresponsive disease. EVIDENCE ACQUISITION: We conducted a literature review using the Cochrane Library, Medline, and Embase and a review of clinical trials in ClinicalTrials.gov as a basis to generate consensus recommendations for clinical trial design in BCG-exposed NMIBC. EVIDENCE SYNTHESIS: BCG-exposed NMIBC encompasses BCG resistance (presence of high-grade Ta or carcinoma in situ [CIS] at 3-mo evaluation after induction BCG) and delayed relapse. Randomized controlled trials are required to compare experimental therapies to a control arm receiving additional BCG, although ongoing BCG shortages may impact our ability to follow an optimal trial design. A placebo should be used in combination with BCG if the treatment arm includes BCG plus a study drug. Trials will either need to separate patients with and without CIS into two cohorts, or stratify by the presence of CIS at the time of randomization. If two cohorts are used, the primary endpoint for CIS patients should be complete response within a predetermined time. The primary endpoint in a cohort with Ta/T1 only, or if a single combined cohort is used, should be the duration of event-free survival. Suggested efficacy thresholds and corresponding sample sizes are provided. CONCLUSIONS: The International Bladder Cancer Group has developed recommendations regarding definitions, endpoints, and clinical trial design for BCG-exposed NMIBC to encourage uniformity among studies in this disease state. PATIENT SUMMARY: Our consensus provides a precise definition of the disease state for bladder cancer not invading the bladder muscle and exposed to bacillus Calmette-Guérin (BCG) treatment. Clear guidance for conducting optimal clinical trials in this disease setting was established and we believe that this will promote further progress in this field.

A review of current guidelines and best practice recommendations for the management of nonmuscle invasive bladder cancer by the International Bladder Cancer Group.

PURPOSE: Although the European Association of Urology, First International Consultation on Bladder Tumors, National Comprehensive Cancer Network and American Urological Association guidelines all provide an excellent evidence-based framework for the management of nonmuscle invasive bladder cancer, these guidelines vary with respect to important issues such as risk level definitions and management strategies for these risk categories. Therefore, we built on the existing framework provided by current guidelines, and provide consensus on the definitions of low, intermediate and high risk nonmuscle invasive bladder cancer, as well as practical recommendations for the treatment of patients in each of these risk categories. MATERIALS AND METHODS: An international committee of experts on bladder cancer management identified and analyzed the European Association of Urology, First International Consultation on Bladder Tumors, National Comprehensive Cancer Network and American Urological Association guidelines as well as the published English language literature related to the treatment and management of nonmuscle invasive bladder cancer available as of April 2010. RESULTS: Based on review of the current guidelines and literature, the International Bladder Cancer Group developed practical recommendations for the management of nonmuscle invasive bladder cancer. CONCLUSIONS: Complete transurethral bladder tumor resection is recommended for all patients with nonmuscle invasive bladder cancer. For low risk disease a single, immediate chemotherapeutic instillation after transurethral bladder tumor resection is recommended. For intermediate or high risk disease there is no significant benefit from an immediate, postoperative chemotherapeutic instillation. For intermediate risk disease intravesical bacillus Calmette-Guérin with maintenance or intravesical chemotherapy is recommended. For high risk disease bacillus Calmette-Guérin induction plus maintenance is recommended. The appropriate management of recurrence depends on the patient level of risk as well as previous treatment, while the management of treatment failure depends on the type of failure as well as the level of risk for recurrence and disease progression.

Can gemcitabine instillation ablate solitary low-risk non-muscle-invasive bladder cancer? Results of a phase II marker lesion study.

PURPOSE: The purpose of this phase II study was to evaluate whether low-risk non-muscle-invasive bladder cancer can be ablated with intravesical gemcitabine in a marker lesion study. PATIENTS AND METHODS: The study had a Simon II-stage design. Thirteen patients were to be recruited for stage I. In the event of ≥4 responses, another 30 patients were to be recruited. Patients were given gemcitabine 2,000 mg intravesically once per week for 6 weeks and the response was assessed with endoscopic, histological, and urine cytological findings. RESULTS: Fourteen patients evaluated for efficacy completed the study; complete responses were achieved by 2 patients (14.3%), both of these patients had lesions of <1 cm. Eleven patients (78.6%) were non-responders and 1 patient (7.1%) had progressive disease. Since the response rate in stage I was below the minimal pre-defined limit, the study was stopped. CONCLUSIONS: This study shows that intravesical gemcitabine does not merit further study in this patient population. A tumor size of >1 cm may be a critical factor in accounting for the low response rate.

Comparison of Tumor Seeding and Recurrence Rate After Laparoscopic vs. Open Nephroureterectomy for Upper Urinary Tract Transitional Cell Carcinoma.

Introduction: Laparoscopic surgery for Upper Urinary Tract Urothelial Cell Carcinoma (UTUC) is still debated for its possible seeding risk and thus consequent oncological recurrences, especially for atypical ones. The aim of the study is to compare recurrence and survival after Laparoscopic vs. Open Radical Nephroureterectomy (RNU) for Upper Urinary Tract Urothelial Cancer (UTUC). Method: A retrospective evaluation of UTUC consecutive surgeries from 2008 to 2019 was conducted, including pT ≥ 2, High Grade UTUC who underwent RNU with bladder cuff excision without concomitant lymphadenectomy in three urological tertiary centers. Statistical analyses compared recurrence and cancer specific survival, based on surgical approach, while logistic multivariate analyses and Kaplan Meyer survival curve analyzed possible risk factors for recurrence and survival. Results: One hundred seven cases of RNU, 47 (43.9%) laparoscopic and 60 (56.1%) open, were included in this report. Preoperative characteristics were comparable between groups. However, tumor stage was higher in the Open arm [T3-T4 in 44 (73.3%) vs. 20 (43.4%) in Laparoscopic]. Mean follow-up was 91.6 months in laparoscopy RNU vs. 93.5 months in open RNU. Recurrence rate (RR) was comparable between groups (p = 0.594), and so was the site, although 3 (6.3%) peritoneal recurrences were found only in laparoscopic group (p = 0.057). At multivariate logistic regression, tumor stage and surgical approach were independent predictors of recurrence (p < 0.05), while only tumor stage was predictor of cancer specific death (p = 0.029). Conclusion: Surgical approach has no impact on recurrence site, overall survival, and RR. Still, according to our data peritoneal carcinomatosis was present only in laparoscopic arm, despite how it didn't reach statistical significance.

5A prospective survey of current prostate biopsy practices among oncological urologists.

BACKGROUND: Needle biopsy of the prostate is a common outpatient procedure. In March 2009, the European Association of Urology (EAU) published an updated, evidence-based "Guidelines on Prostate Cancer," including recommendations for this procedure. OBJECTIVE: To survey onco-urology specialists attending the 6th European Section of Oncological Urology (ESOU) meeting in Istanbul, Turkey in January 2009, to assess their biopsy practices and compare them with March 2009 EAU guidelines. DESIGN, SETTING AND PARTICIPANTS: The authors designed a questionnaire and distributed it to 606 conference delegates. It was completed by 298 delegates, of whom 156 were experienced onco-urological specialists. MEASUREMENTS: The survey results from the 156 experienced onco-urologist specialists were analyzed. RESULTS AND LIMITATIONS: Most (59%) of the 156 respondents worked in large (> 20 bed) units, and 76% said urologists always performed the biopsies. Transrectal ultrasound (TRUS)-guided biopsy was the preferred procedure for 78% of respondents. Prostate-specific antigen (PSA) cut-off points of 4 ng/mL, 3.5 ng/mL, 3 ng/mL, and 2.5 ng/ml were used by 42%, 18%, 23%, and 8% of respondents, respectively, to determine whether a biopsy was indicated. A total of 95% of respondents gave patients prophylactic antibiotics. Another of 15% and 17% of respondents did not advise patients to stop taking warfarin or clopidogrel, respectively. A total of 23% of respondents did not give patients pre-procedure anesthesia, while others gave patients periprostatic lidocaine (31% of respondents), topical lidocaine jelly (35%), or general or spinal anesthesia (5.7%). High grade prostatic intraepithelial neoplasia (HGPIN) was considered by 71% of respondents as being a pre-malignant condition requiring a repeat biopsy. If atypical small acinar proliferation (ASAP) was reported, 62% of respondents recommended a repeat biopsy. Magnetic resonance imaging (MRI) was used to help diagnose cancer (53% of respondents), help stage cancer (83%), or help diagnose cancer recurrence (62%). Study limitations include possible difficulties with the English questionnaire. CONCLUSIONS: Many surveyed specialists were not performing prostate biopsies according to March 2009 evidence-based EAU practice guidelines, which could have adverse consequences for patients.

Management of Patients with Normal Cystoscopy but Positive Cytology or Urine Markers.

This presentation considers follow-up after successful transurethral resection of a high-grade non-muscle-invasive tumour, with normal cystoscopy, followed by bacillus-Calmette-Guérin (BCG) therapy. Focusing on two possible outcomes, a positive cytology but a negative urinary biomarker result, versus positive biomarkers but a negative cytology, we discuss what the evidence and guidelines recommend and which test is more robust. PATIENT SUMMARY: Bladder cancer is usually assessed by examination of tissue taken from the bladder, either by surgery or by biopsy; however, trace elements in the urine, known as biomarkers, can also provide an assessment. The challenge arises when the two methods do not agree: the tissue sample is positive for cancer, but the biomarker is negative, or the reverse. For now, these authors conclude that the tissue examination is more reliable than the biomarker result.
