ICUD-SIU International Consultation on Bladder Cancer 2017: management of non-muscle invasive bladder cancer.

PURPOSE: To provide a summary of the Third International Consultation on Bladder Cancer recommendations for the management of non-muscle invasive bladder cancer (NMIBC). METHODS: A detailed review of the literature was performed focusing on original articles for the management of NMIBC. An international committee assessed and graded the articles based on the Oxford Centre for Evidence-based Medicine system. The entire spectrum of NMIBC was covered such as prognostic factors of recurrence and progression, risk stratification, staging, management of positive urine cytology with negative white light cystoscopy, indications of bladder and prostatic urethral biopsies, management of Ta low grade (LG) and high risk tumors (Ta high grade [HG], T1, carcinoma in situ [CIS]), impact of BCG strain and host on outcomes, management of complications of intravesical therapy, role of alternative therapies, indications for early cystectomy, surveillance strategies, and new treatments. The working group provides several recommendations on the management of NMIBC. RESULTS: Recommendations were summarized with regard to staging; management of primary and recurrent LG Ta and high risk disease, positive urine cytology with negative white light cystoscopy and prostatic urethral involvement; indications for timely cystectomy; and surveillance strategies. CONCLUSION: NMIBC remains a common and challenging malignancy to manage. Accurate staging, grading, and risk stratification are critical determinants of the management and outcomes of these patients. Current tools for risk stratification are limited but informative, and should be used in clinical practice when determining diagnosis, surveillance, and treatment of NMIBC.

Padeliporfin vascular-targeted photodynamic therapy versus active surveillance in men with low-risk prostate cancer (CLIN1001 PCM301): an open-label, phase 3, randomised controlled trial.

BACKGROUND: Vascular-targeted photodynamic therapy, a novel tissue-preserving treatment for low-risk prostate cancer, has shown favourable safety and efficacy results in single-arm phase 1 and 2 studies. We compared this treatment with the standard of care, active surveillance, in men with low-risk prostate cancer in a phase 3 trial. METHODS: This randomised controlled trial was done in 47 European university centres and community hospitals. Men with low-risk, localised prostate cancer (Gleason pattern 3) who had received no previous treatment were randomly assigned (1:1) to vascular-targeted photodynamic therapy (4 mg/kg padeliporfin intravenously over 10 min and optical fibres inserted into the prostate to cover the desired treatment zone and subsequent activation by laser light 753 nm with a fixed power of 150 mW/cm for 22 min 15 s) or active surveillance. Randomisation was done by a web-based allocation system stratified by centre with balanced blocks of two or four patients. Best practice for active surveillance at the time of study design was followed (ie, biopsy at 12-month intervals and prostate-specific antigen measurement and digital rectal examination at 3-month intervals). The co-primary endpoints were treatment failure (histological progression of cancer from low to moderate or high risk or death during 24 months' follow-up) and absence of definite cancer (absence of any histology result definitely positive for cancer at month 24). Analysis was by intention to treat. Treatment was open-label, but investigators assessing primary efficacy outcomes were masked to treatment allocation. This trial is registered with ClinicalTrials.gov, number NCT01310894. FINDINGS: Between March 8, 2011, and April 30, 2013, we randomly assigned 206 patients to vascular-targeted photodynamic therapy and 207 patients to active surveillance. Median follow-up was 24 months (IQR 24-25). The proportion of participants who had disease progression at month 24 was 58 (28%) of 206 in the vascular-targeted photodynamic therapy group compared with 120 (58%) of 207 in the active surveillance group (adjusted hazard ratio 0·34, 95% CI 0·24-0·46; p<0·0001). 101 (49%) men in the vascular-targeted photodynamic therapy group had a negative prostate biopsy result at 24 months post treatment compared with 28 (14%) men in the active surveillance group (adjusted risk ratio 3·67, 95% CI 2·53-5·33; p<0·0001). Vascular-targeted photodynamic therapy was well tolerated. The most common grade 3-4 adverse events were prostatitis (three [2%] in the vascular-targeted photodynamic therapy group vs one [<1%] in the active surveillance group), acute urinary retention (three [2%] vs one [<1%]) and erectile dysfunction (two [1%] vs three [1%]). The most common serious adverse event in the vascular-targeted photodynamic therapy group was retention of urine (15 patients; severe in three); this event resolved within 2 months in all patients. The most common serious adverse event in the active surveillance group was myocardial infarction (three patients). INTERPRETATION: Padeliporfin vascular-targeted photodynamic therapy is a safe, effective treatment for low-risk, localised prostate cancer. This treatment might allow more men to consider a tissue-preserving approach and defer or avoid radical therapy. FUNDING: Steba Biotech.

The role of cystectomy in elderly patients - a multicentre analysis.

INTRODUCTION: Life expectancy in developed countries is continuously increasing. Hence elderly patients are becoming more common in our clinical practice. Currently, one of the greatest challenges of medicine is balancing the life expectancy of elderly patients against aggressive treatments that carry significant risks. OBJECTIVE: To outline the complications and survival in surgical patients 80 years and over undergoing radical cystectomy for bladder cancer. PATIENTS AND METHODS: A review of a radical cystectomy in elderly recorded in four different institutional prospective databases during the period between 1991 and 2014. Clinical and pathologic features, complications and survival were evaluated. RESULTS: A total of 111 patients were available. Median (range) age 82.2 (80-89) years. Seventeen women and 94 men. Regarding the ASA score, 6 patients were ASA I, 47 patients were ASA II, 49 patients ASA III and 9 ASA IV. Prior to surgery, 48 patients had hydronephrosis. The median (range) creatinine series was 1.1 (0.71-11.1) ng/dL. In 88 cases an ileal conduit was performed, 17 a cutaneous ureterostomy diversion, 5 neobladders and 1 ureterosigmoidostomy case. The median (range) operative time was 230 (120-420) min and a total of 97 patients required blood transfusion. The median (range) hospital stay was 14 (7-126) days. The early and late complication rates were 50.4% and 32%, respectively. A total of 14 patients (12.6%) required surgical reintervention. Eight patients (7.2%) died in the immediate postoperative period. The readmission rate of the series was 27.2%. The mean follow-up of the series was 18 (0.27-134.73) months. During this period 66 patients died, 52 of them due to the tumor. Twelve month tumour progression free survival was 83.9% for ≤pT1, 70.2% for pT2 and 36% for ≥pT3, respectively. Twelve month cancer specific survival was 85.6% for ≤pT1, 75.1% for pT2 and 42.5% for ≥pT3, respectively. CONCLUSION: Radical cystectomy in elderly population is an aggressive surgical treatment with a significant complication rate, hospital readmission and perioperative mortality rate. Careful selection of patients is essential in order to minimize the complications of this surgery and balance benefits against risks in the elderly population. Tumour progression and cancer specific survival are poor for patients with ≥pT3 disease. Alternatives such as tri-modality therapy need to be considered within a multi-disciplinary approach. More data is required to determine which sub-groups of elderly patients would benefit from a complication, survival and quality of life perspective.

Effectiveness of hexaminolevulinate fluorescence cystoscopy for the diagnosis of non-muscle-invasive bladder cancer in daily clinical practice: a Spanish multicentre observational study.

OBJECTIVE: To assess the sensitivity and specificity of blue-light cystoscopy (BLC) with hexaminolevulinate as an adjunct to white-light cystoscopy (WLC) vs WLC alone for the detection of non-muscle-invasive bladder cancer (NMIBC), in routine clinical practice in Spain. PATIENTS AND METHOD: An intra-patient comparative, multicentre, prospective, observational study. Adults with suspected or documented primary or recurrent NMIBC at eight Spanish centres were included in the study. All patients were examined with WLC followed by BLC with hexaminolevulinate. We evaluated the detection rate of bladder cancer lesions by WLC and BLC with hexaminolevulinate, overall and by tumour stage and compared with histological examination of the biopsied lesions. Sensitivity and specificity was calculated. RESULTS: In all, 1,569 lesions were identified from 283 patients: 621 were tumour lesions according to histology and 948 were false-positives. Of the 621 tumour lesions, 475 were detected by WLC (sensitivity 76.5%, 95% confidence interval [CI] 73.2-79.8) and 579 were detected by BLC (sensitivity 93.2%, 95% CI 91.0-95.1; P < 0.001). There was a significant improvement in the sensitivity in the detection of all types of NMIBC lesions with BLC compared with WLC. Of 219 patients with tumours, 188 had NMIBC [highest grade: carcinoma in situ (CIS), n = 36; Ta, n = 87; T1, n = 65). CIS lesions were identified more with BLC (n = 27) than with WLC [n = 19; sensitivity: BLC 75.0% (95% CI 57.8-87.9) vs WLC 52.8% (95% CI 35.5-69.6); P = 0.021]. Results varied across centres. CONCLUSIONS: This study shows that improvement in diagnosis of NMIBC, mainly CIS and Ta tumours, obtained with BLC with hexaminolevulinate as an adjunct to WLC vs WLC alone can be shown in routine clinical practice.

Implementing the use of nomograms by choosing threshold points in predictive models: 2012 updated Partin Tables vs a European predictive nomogram for organ-confined disease in prostate cancer.

OBJECTIVES: To implement the use of nomograms in clinical practice showing how to choose thresholds in nomograms' predictions to select risk groups. To validate and compare the predictive ability and clinical utility of the Hospital Universitario 'Miguel Servet' (HUMS) and the updated Partin Tables 2012 (PT-2012) nomograms to predict organ-confined disease (OCD) after radical prostatectomy (RP). PATIENTS AND METHODS: Cohort of 1285 patients with prostate cancer treated with RP at Instituto Valenciano de Oncología (IVO) between 1986 and 2011. The predictive value of the nomograms was assessed by means of calibration curves, discrimination ability (area under the receiver operating characteristic (ROC) curve (AUC) and probability density functions). The clinical utility was evaluated through Vickers' decision curves and thresholds were chosen through probability density functions. RESULTS: The calibration curves showed a minimal underestimation in low probabilities (<20%), a minimal overestimation in high probabilities (>50%) in the HUMS nomogram and a regular minimal overestimation in the PT-2012. Their AUC of 0.7285 (95% confidence interval [CI] 0.7010-0.7559) and 0.7288 (95%CI 0.7013-0.7562) respectively, show an adequate discrimination ability for both predictive models in the IVO cohort. The decision curves show similar net benefits for both models. In this study we advocate for a threshold of 53% for the identification of OCD. CONCLUSIONS: The HUMS-nomogram and the PT-2012 predictions of OCD confirm their utility in a contemporary cohort of patients. Patients with a probability of OCD >53% should be classified as OCD, helping physicians to better counsel their patients. A selection of adequate thresholds, as presented in this paper, makes nomograms more accessible tools.

Hyperthermic Mitomycin C in Intermediate-risk Non-muscle-invasive Bladder Cancer: Results of the HIVEC-1 Trial.

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 ±â€¯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.

Restaging transurethral resection of bladder tumor for high-risk stage Ta and T1 bladder cancer.

Bladder cancer is the most common malignancy of the urinary tract. About 75%-85% of patients present with non-muscle-invasive bladder cancer (NMIBC). However, patients with pT1 tumors, as well as all those with high-grade disease, make up a subset with a high-risk of recurrence and disease progression. Although still regarded as the gold standard, clinical evidence from contemporary published series clearly demonstrates that transurethral resection of tumor (TUR) is a procedure far from optimal, highlighting its limitations and the need for further diagnostic accuracy. Routine use of a restaging TUR (re-TUR), supported by the American Urological Association and European Association of Urology guidelines, detects residual tumor in a significant number of cases after initial TUR. It provides a more accurate staging of the disease and, consequently, helps to guide its treatment. Recent years have seen rapid development of novel optical techniques aimed to optimize resection. Routine implementation of these novel techniques in the context of re-TUR is promising and may potentially result in more tumors being identified and completely resected, leading to significantly lower residual tumor rates than with the standard white-light TUR. This article will focus on re-TUR in the management of high-risk NMIBC, with an up-to-date review of the available literature and detailed analysis of the published series.

[Radical prostatectomy after radiotherapy]. / La prostatectomía radical tras radioterapia.

Radical prostatectomy is an excellent salvage method for patients with prostatic cancer when radical radiotherapy or brachytherapy fail. To define local failure is not always reliable; nevertheless, performing a prostatic biopsy two years after treatment could reach an early diagnosis. Another accepted attitude is to perform the biopsy after biochemical recurrence, but sometimes the pathological stage is already locally advanced tumor. It is also difficult to determine which patients are suitable for this rescue treatment, probably those with locally confined tumors and with favorable PSA kinetics, PSA velocity below 2.0 or a PSA doubling time over 12 months, and in whom detectable PSA is reached 2 years after treatment. These patients are suitable for radical prostatectomy if they have a live expectancy of more than 10 years. Although rescue radical prostatectomy has a higher rate of complications and worse functional results, cancer-specific survival rates are high, and remain high after 15 years of follow-up. Currently, new surgical improvements and new radiotherapy technology are diminishing surgical complications and improving functional results. In summary radical prostatectomy is a feasible rescue procedure after radiotherapy failure although the complications rate remains higher than prostatectomy as initial therapy.

Prostate cancer in Spain: from guidelines to clinical practice.

OBJECTIVE: • To determine how closely practice in prostate cancer (PCa) follows European Association of Urology (EAU) guidelines. MATERIALS AND METHODS: • This project involving 242 experts comprised four phases: (1) selection of controversial topics by a panel of experts; (2) preparation of case descriptions and associated questionnaires; (3) determination of their face validity; and (4) completion (November 2007 to January 2008). • The primary endpoint was percentage agreement with the recommendations given by the EAU guidelines. Topics not specifically addressed in these guidelines were also analysed. RESULTS: • For the selected controversial topics, the overall mean adherence to the guidelines was 52.1%. Topics with a mean adherence <40% are detailed below. • For localized/locally advanced PCa the lowest adherence was found for the type of anaesthesia used during biopsy (30.3%, sd= 14.4), local staging (17.3%, sd= 10.4), new criteria for biochemical relapse after radiotherapy (32.9%, sd= 27.6), and the interpretation of raised PSA after prostatectomy (34.4%, sd= 20.1). • For metastatic PCa, the lowest adherence referred to androgen blockade (34.5%, sd= 24.94) and the reintroduction of hormone therapy (21.8%, sd= 13.5). • Regarding the monitoring of patients, 83.9% of the urologists stated that they measure testosterone levels at some point, and the conventional threshold level of 50 ng/dL testosterone was only used by 17.4%. • Differences in opinion were also observed for the recommendation for a digital rectal examination at each visit (agreed by only 22.3%). CONCLUSION: • The PROSEO project represents an opportunity to consolidate and improve EAU guidelines by identifying issues that, on the basis of clinical practice in PCa and topics of current concern to urologists, have not been fully addressed or might need specific recommendations.

Feasibility of radical transurethral resection as monotherapy for selected patients with muscle invasive bladder cancer.

PURPOSE: We proved the feasibility of radical transurethral bladder tumor resection in selected patients with muscle invasive bladder cancer with a minimum followup of more than 15 years and investigated the impact of patient age on survival. A followup schedule was developed based on progression and recurrence during this period. MATERIALS AND METHODS: A phase II nonrandomized trial was designed including patients with muscle invasive bladder cancer with negative biopsies of tumor bed who were apparently healthy after undergoing complete transurethral bladder tumor resection. Patients with positive biopsies, or with macroscopically residual tumor, hydronephrosis or metastasis were excluded from study. In this trial 133 patients fulfilled the inclusion criteria and had a minimum followup of more than 15 years. RESULTS: Cancer specific survival was 81.9%, 79.5% and 76.7%, and progression-free survival with bladder preservation was 75.5%, 64.9% and 57.8% at 5, 10 and 15 years, respectively. Patient age had a negative impact on overall survival on univariate (HR 0.842, p = 0.049) and multivariate analyses (HR 1.062, p = 0.000), and according to median and quartile age stratifications (p = 0.000 and p = 0.000, respectively). However, age did not have a negative impact on cancer specific survival even when following the same stratifications. Although progression and recurrence were concentrated during the first 3 years (70% and 65%, respectively), both steadily increased afterward. A followup schedule was developed according to this sequence of events. CONCLUSIONS: Radical transurethral bladder tumor resection is a reliable therapeutic approach for patients with muscle invasive bladder cancer after complete tumor resection and with negative biopsies of the tumor bed. These results are consistent in all age ranges.

Clinical implications of TMPRSS2-ERG gene fusion expression in patients with prostate cancer treated with radical prostatectomy.

PURPOSE: Molecular prognostic factors may be useful tools for prostate cancer that complement classic clinicopathological factors. Genetic rearrangements between TMPRSS2 and ETS have been described for prostate cancer but their clinical significance is still unclear. We analyzed the association of the TMPRSS2-ERG fusion gene with prostate cancer outcome in patients treated with radical prostatectomy. MATERIAL AND METHODS: We analyzed prostate cancer samples from 226 patients treated with radical prostatectomy from 1996 to 2002 with a median followup of 84 months (range 9 to 153). TMPRSS2-ERG fusion gene expression was determined by reverse transcriptase-polymerase chain reaction. Clinicopathological and molecular variables were related to biochemical and clinical progression-free survival by the Kaplan-Meier proportional risk log rank test. A Cox proportional hazards model using stepwise selection was used to identify independent predictors of poor outcome. RESULTS: TMPRSS2-ERG fusion was detected in 114 cases (50.4%). We noted no association between fusion gene status and prostate cancer clinicopathological characteristics. However, when patients were grouped by TMPRSS2-ERG fusion gene status, different clinicopathological prognostic factors defined each group for biochemical and clinical progression-free survival. Prostate specific antigen, specimen Gleason score and margin status were independent prognostic factors in patients with prostate cancer expressing the fusion gene. In the nonexpressing TMPRSS2-ERG group the prognostic factors were cT, Gleason score and margins. CONCLUSIONS: TMPRSS2-ERG fusion gene status classifies patients with prostate cancer treated with radical prostatectomy into groups defined by different prognostic factors. This could be the basis for designing more refined treatment strategies.

Trimodal therapy in muscle invasive bladder cancer management.

INTRODUCTION: Radical cystectomy (RC) is the current mainstay for muscle-invasive bladder cancer (MIBC). Concerns regarding morbidity, mortality and quality of life have favored the introduction of bladder sparing strategies. Trimodal therapy, combining transurethral resection, chemotherapy and radiotherapy is the current standard of care for bladder preservation strategies in selected patients with MIBC. EVIDENCE ACQUISITION: A comprehensive search of the Medline and Embase databases was performed. A total of 19 studies were included in a systematic review of bladder sparing strategies in MIBC management was carried out following the preferred reporting items for systematic reviews and meta-analysis (PRISMA). EVIDENCE SYNTHESIS: The overall median complete response rate after trimodal therapy (TMT) was 77% (55-93). Salvage cystectomy rate with TMT was 17% on average (8-30). For TMT, the 5-year cancer-specific survival and overall survival rates range from 42-82% and 32-74%, respectively. Currently data supporting neoadjuvant or adjuvant chemotherapy in bladder sparing approaches are emerging, but robust definitive conclusions are still lacking. Gastrointestinal toxicity rates are low around 4% (0.5-16), whereas genitourinary toxicity rates reached 8% (1-24). Quality of life outcomes are still underreported. CONCLUSIONS: Published data and clinical experience strongly support trimodal therapy as an acceptable bladder sparing strategy in terms of oncological outcomes and quality of life in selected patients with MIBC. A strong need exists for specialized centers, to increase awareness among urologists, to discuss these options with patients and to stress the increased participation of patients and their families in treatment path decision-making.

Predicting nonmuscle invasive bladder cancer recurrence and progression in patients treated with bacillus Calmette-Guerin: the CUETO scoring model.

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

[Which patients with stress urinary incontinence after radical prostatectomy benefit from the indication of an Invance?]. / ?Qué pacientes con incontinencia de esfuerzo tras prostatectomía radical se benefician de la indicación de Invance?

OBJECTIVES: Stress urinary incontinence alter radical prostatectomy is one of the most worrisome sequelae for the patient and urologist. The aim of this paper is to evaluate the indications of the suburethral mesh Invance, giving details on our preoperative evaluation and indication, surgical technique, and the correlation between preoperative findings and functional results. METHODS: Between February 2006 and January 2009 27 patients underwent surgery. All of them had more than one year of follow up after prostatectomy, urodynamic study and preoperative cystoscopy. Continence was evaluated by the number of pads/day and the ICIQ-UI SF questionnaire. Through a perineal incision three titanium screws with a polipropylene suture were inserted in each ischiopubic rami, and a silicon/polipropylene mesh (Invance) is affixed to them, compressing the bulbar urethra. Patients were divided into two groups: good prognosis (1-2 pads/day without urodynamic anomalies in the filling phase) and bad prognosis (3 pads/day, history of radiotherapy or bladder neck incision, and urodynamic anomalies). Cure was defined as a patient not needing pads, and improvement was defined as decrease in the number of pads per day. RESULTS: Median follow up after Invance was 18 months (4-38). Nine patients used one pad/day, 10 used two, and eight used three pads /day. Six cases had underwent previous bladder neck incision and three radiotherapy. Globally, 20 patients (74% ) were cured and five (19% ) had improved. Cure rate was 100% in the good prognosis group and 61% in the bad prognosis group (p=0.03). No intraoperative complications were registered. During the immediate postoperative period,one patient required cystostomy tube for 10 days. Seven patients (26% ) presented perineal discomfort; neither de novo urgency nor urethral erosion nor sling explants due to infection were registered. CONCLUSIONS: Invance is a safe technique that guarantees a high continence rate in selected patients. It is a reproducible operation and, with a midterm follow up, no loss of continence has been observed, and the risk of urethral erosion is null in our experience. Patients with mild-moderate incontinence, without urodynamic anomalies nor previous radiotherapy are the ideal candidates.

[EMDA with MMC. Critical review.] / EMDA con MMC. Revisión crítica.

Two Phase II studies, three Phase III and one observational study seem to justify that EMDA-MMC is a real alternative in the treatment of patients with NMIBC, especially the high risk group. The phase III studies compare EMDA-MMC with passive diffusion MMC and BCG in patients with bladder TIS. They showed EMDA MMC superiority compared to passive diffusion MMC and similar to BCG in achieving complete response at 3 and 6 months. In another randomized study on pT1 NMIBC patients, comparing a sequential scheme of BCG plus EMDA-MMC and BCG, the sequential regimen was significantly superior than BCG reducing recurrence and progression and improved overall and specific survivals. A third randomized study compared TURBT only with immediate post TURBT MMC instillation and EMDA-MMC preoperative instillation. This latter showed to be superior in recurrence prevention than the other two schemes. Tolerance to EMDA-MMC is inferior to passive diffusion MMC, but it does not reach statistical significance. In the same way, EMDA-MMC tolerance is better than BCG and there is no difference between this and the sequential scheme of BCG plus EMDA-MMC. Methodological defects observed in these studies and the fact that almost all of them come from the same group makes it necessary to reproduce this data in other centers so that this therapeutic alternative could be included in guidelines.

[Consensus on castration-resistant prostate cancer management in Spain.] / Consenso sobre el manejo del cáncer de próstata resistente a la castración avanzado en España.

OBJECTIVES: To move towards a more standardized approach in clinical practice to manage patients with castration-resistant prostate cancer (CRPC) in Spain. METHODS: A panel of 18 Spanish experts in Urology with expertise managing CRPC followed a modified Delphi process with two rounds and a final face-to-face consensus meeting. The panel considered a total of 106 clinical questions divided into the following 6 sections: definition of CRPC, diagnosis of metastases by imaging techniques, symptoms of CRPC, progression of CRPC, M0 and M1 management and therapeutic sequencing. RESULTS: A bone scan (BS) is recommended at diagnosis, at the onset of bone pain, and depending on PSA levels, but it is not sensitive enough to confirm or exclude bone metastases if there is bone pain. Whole-body MRI and axial MRI are more sensitive than BS and plain X-rays, but more expensive, so they have to be used in certain situations. There is CRPC progression when there is radiologic, clinical or confirmed PSA progression. Flare phenomenon appears in treatment with taxanes and abiraterone. It was agreed that in M0 CRPC patients no drug treatment is currently recommended, although in M1 CRPC patients the first-line therapy would be mainly enzalutamide/abiraterone and/or docetaxel, depending on the symptom burden. CONCLUSION: After the consensus, we provide a series of recommendations for Spanish physicians treating CRPC to address the disease characteristics,how to tailor patient management decisions, the use of imaging techniques, and how to handle disease progression appropriately to improve patients' quality of life.

Best approach for low-risk superficial bladder cancer.

In order to create better criteria for different grades of superficial bladder tumor, the WHO and ISUOP develop a new classification in 1998, which was modified in 2004. Although the new classification might be more reproducible, it has not yet been widely accepted. The low risk groups include patients with single Ta, G1, < or = 3 cm diameter tumors. This group has high recurrence and low progression rates. The standard treatment is the complete resection and postoperative single immediate instillation of whatever chemotherapy agent should be considered.

Expert opinion on first-line therapy in the treatment of castration-resistant prostate cancer.

Treatment of metastatic castration-resistant prostate cancer (mCRPC) has been revolutionized in recent years. It is well known that androgen receptor is still active in most patients with disease progression and serum testosterone levels <50 ng/dL. Moreover, further hormonal maneuvers, either through decreasing androgen levels (abiraterone) or by targeting the androgen receptor (AR) pathway (enzalutamide), prolong survival. In addition, a new cytostatic able to overcome docetaxel resistance, cabazitaxel, and the radioisotope radium 223 have been incorporated to the armamentarium of mCRPC. mCRPC is not only a heterogeneous tumor, it changes over time developing neuroendocrine features or selection of clones resistant to hormonal maneuvers. In addition, the multiplicity of current treatments, make it necessary to design algorithms that help the specialist to choose the most appropriate treatment for a particular patient. The lack of randomized trials comparing face to face the different available options limit the scope of this review. In this article, the authors describe the prognostic factors for first line therapy in patients with mCRPC, and propose a treatment algorithm for mCRPC based on the levels of scientific evidence available and, if not available, on the consensus between medical professionals. Finally, the panel discuss how to define progressive disease in the setting of mCRPC and treatment with targeted therapies.

Systematic Review and Individual Patient Data Meta-analysis of Randomized Trials Comparing a Single Immediate Instillation of Chemotherapy After Transurethral Resection with Transurethral Resection Alone in Patients with Stage pTa-pT1 Urothelial Carcinoma of the Bladder: Which Patients Benefit from the Instillation?

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.

High-risk nonmuscle invasive bladder cancer.

Please also verify that the expansion of HGT1 is OK as set: The risk of progression for high-grade T1 (HGT1) cancer has been recently established at 21% using updated information on large series and a meta-analysis. These outcomes are better than those classically expected supporting the rule of thirds for HGT1. The main limitation of this subgroup is that most studies are retrospective observational studies, which, compared with randomized controlled trials, are subject to various selection biases, carrying a higher risk of uncontrolled confounding factors, with potential preferential reporting of positive findings.
