RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

OBJECTIVE: Penile cancer has a predominantly lymphatic dissemination. Lymph nodes metastatic involvement conditions disease prognosis and inguinal lymph node dissection has both prognostic and therapeutic value. High and intermediate risk patients with non-palpable lymph nodes will benefit of a precise diagnosis by means of selective sentinel node biopsy with minimal surgical aggressiveness. METHODS: Retrospective review of our experience on dynamic sentinel node biopsy in penile cancer from November 1999 to July 2014. RESULTS: We performed this procedure in 33 patients, technically successful in 29 (88%). The patients who did not undergo lymph node dissection due to positive sentinel node biopsy have been followed a mean of 60.4 months (Median 59, range 5-145). 20 patients underwent simultaneous sentinel node biopsy and surgical treatment of the primary lesion and in 13 it was performed posteriorly. In these cases the time lapse was 5.5 months (median 5, range 2-12). In 6 (18.9%) of the 29 patients successfully biopsied, metastasis was founded in any of the lymph nodes identified as sentinel. Two patients were false negative (6,25%). Sensitivity (S), specificity (Sp), positive predictive value (PPV) and negative predictive value (NPV) of successfully performed sentinel node biopsies were 66, 100, 100 and 93%, respectively. CONCLUSION: Sentinel node biopsy enables a correct lymph node staging avoiding the morbidity of inguinal lymph node dissection. The rate of technical failure and false negative results is low and it may be considered the diagnostic technique of choice in high and intermediate risk penile cancer with non-palpable lymph nodes.

RESUMO

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.

RESUMO

BACKGROUND: Bacillus Calmette-Guérin (BCG) maintenance therapy for 3 yr following BCG induction can reduce the progression of urothelial bladder carcinoma versus BCG induction alone, but is associated with high toxicity. OBJECTIVE: To investigate whether a modified 3-yr BCG maintenance regimen following induction therapy is more effective than standard BCG induction therapy alone and exhibits a low toxicity profile. DESIGN, SETTING, AND PARTICIPANTS: Patients from the outpatient clinics of the participating centres with high-risk non-muscle-invasive bladder carcinoma (NMIBC) were randomised between October 1999 and April 2007. INTERVENTION: Participants received BCG induction once-weekly for 6 wk (no maintenance arm) or BCG induction followed by one BCG instillation every 3 mo for 3 yr (maintenance arm). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Primary endpoints were disease-free interval (DFI) and time to progression (TTP). Secondary endpoints included survival duration and toxicity. Differences between treatment arms were tested using Student's t test and χ(2) and log-rank tests. RESULTS AND LIMITATIONS: A total of 397 patients were randomised, 195 to the no-maintenance and 202 to the maintenance arm. A median time to recurrence was not reached in either treatment arm. DFI was similar between the arms (hazard ration [HR] 0.83; 95% CI 0.61-1.13; p=0.2) with disease relapse at 5 yr of 33.5% and 38.5%, respectively. TTP was also similar between the treatment arms (HR 0.79; 95% CI 0.50-1.26; p=0.3), with a progression rate at 5 yr of 16% and 19.5%, respectively. There were no significant differences between the treatment groups for overall survival and cancer-specific survival at 5 yr. Twenty and five patients in the maintenance and no-maintenance arms, respectively, stopped treatment because of toxicity. The most common local side effects were frequency (65% of patients), dysuria (63%), and haematuria (43%); the most frequent systemic side effects were general malaise (7.2%) and fever (34%). CONCLUSIONS: In NMIBC patients treated with maintenance therapy comprising a single BCG instillation every 3 mo for 3 yr following standard induction BCG, we did not observe a decrease in recurrence and progression rates versus induction therapy alone. PATIENT SUMMARY: Patients who undergo surgery to remove bladder cancer are usually treated with bacillus Calmette-Guérin (BCG) for 6 wk if there is a high risk of disease recurrence. Extending BCG therapy by 3 yr can further minimise disease recurrence and progression, but is associated with more side effects. We report that a modified 3-yr BCG treatment regimen showed low toxicity, but seemed to be no more effective than 6-wk treatment. TRIAL REGISTRATION: CUETO 98013.

RESUMO

BACKGROUND: Intravesical bacillus Calmette-Guérin (BCG) is an effective therapy in non-muscle-invasive bladder cancer (NMIBC), but it has limitations in terms of recurrence and toxicity. OBJECTIVE: To determine whether the sequential combination of mitomycin C (MMC) and BCG is superior to BCG alone in increasing a disease-free interval (DFI). DESIGN, SETTING, AND PARTICIPANTS: We conducted a prospective randomized trial including 407 patients with intermediate- to high-risk NMIBC and allocated 211 to the MMC and BCG arm and 196 to the BCG-alone arm. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The trial was designed to provide concurrently a power of 80% for the detection of a relative risk reduction of 35% (hazard ratio [HR]: 0.65) of disease relapse with a type I error of 0.05. Times to events were estimated using cumulative incidence functions and compared using the Cox regression model. We used the Kaplan-Meier technique to estimate survival curves. RESULTS AND LIMITATIONS: In the intention-to-treat analysis at 5 yr, DFI was significantly improved by the sequential scheme (HR: 0.57; 95% confidence interval [CI], 0.39-0.83; p=0.003), reducing the disease relapse rate from 33.9% to 20.6%. Higher toxicity was observed with the combination, even reducing the MMC dose, especially in G3 local toxicity compared with BCG with a difference of 17.4% (95% CI, 7.6-27.2; p<0.001). In recurrent T1 tumors, the potential benefit of the sequential scheme was more evident than in the remaining subgroup (18.8% vs 12.8%), with a number needed to treat of five versus eight to avoid an event and with similar toxicity. CONCLUSIONS: Although the sequential scheme is more effective than BCG alone in reducing disease relapse, due to higher toxicity it could be offered only to patients with a high likelihood of recurrence, such as those with recurrent T1 tumors. PATIENT SUMMARY: We analyzed the outcomes of a randomized trial demonstrating that in intermediate- to high-risk non-muscle-invasive bladder cancer, mitomycin C and bacillus Calmette-Guérin (BCG) reduced disease relapse compared with BCG alone but was more toxic. Consequently, it could be offered only to patients with recurrent T1 tumors. TRIAL REGISTRATION: CUETO 93009.

RESUMO

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.

RESUMO

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.

RESUMO

CONTEXT: Our aim was to present a summary of the Second International Consultation on Bladder Cancer recommendations on the diagnosis and treatment options for non-muscle-invasive urothelial cancer of the bladder (NMIBC) using an evidence-based approach. OBJECTIVE: To critically review the recent data on the management of NMIBC to arrive at a general consensus. EVIDENCE ACQUISITION: A detailed Medline analysis was performed for original articles addressing the treatment of NMIBC with regard to diagnosis, surgery, intravesical chemotherapy, and follow-up. Proceedings from the last 5 yr of major conferences were also searched. EVIDENCE SYNTHESIS: The major findings are presented in an evidence-based fashion. We analyzed large retrospective and prospective studies. CONCLUSIONS: Urothelial cancer of the bladder staged Ta, T1, and carcinoma in situ (CIS), also indicated as NMIBC, poses greatly varying but uniformly demanding challenges to urologic care. On the one hand, the high recurrence rate and low progression rate with Ta low-grade demand risk-adapted treatment and surveillance to provide thorough care while minimizing treatment-related burden. On the other hand, the propensity of Ta high-grade, T1, and CIS to progress demands intense care and timely consideration of radical cystectomy.

RESUMO

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.

RESUMO

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.
