RESUMO

PURPOSE: Limited high-quality studies have compared robot-assisted laparoscopic prostatectomy (RALP) vs open retropubic radical prostatectomy. We sought to compare their postoperative outcomes in a randomized setting. MATERIALS AND METHODS: In a single center, 354 men with newly diagnosed prostate cancer were assessed for eligibility; 342 were randomized (1:1). The primary outcome was 90-day complication rates. Functional outcomes and quality of life were assessed over 18 months, and oncological outcomes, biochemical recurrence-free survival, and additional treatment over 36 months. RESULTS: From 2014 to 18, 327 patients underwent surgery (retropubic radical prostatectomy = 156, RALP = 171). Complications occurred in 27 (17.3%) vs 19 (11.1%; P = .107). Patients undergoing RALP experienced lower median bleeding (250.0 vs 719.5 mL; P < .001) and shorter hospitalization time. Urinary EPIC (Expanded Prostate Cancer Index Composite) median scores were better for RALP over 18 months, with higher continence rate at 3 months (80.5% vs 64.7%; P = .002), 6 months (90.1% vs 81.6%; P = .036) and 18 months (95.4% vs 78.8%; P < .001). Sexual EPIC and Sexual Health Inventory for Men median scores were higher with RALP up to 12 months, while the potency rate was superior at 3 months (23.9% vs 5.3%; P = .001) and 6 months (30.6% vs 6.9%; P < .001). Quality of life over the 18 months and oncological outcomes over 36 months were not significantly different between arms. CONCLUSIONS: Complications at 90 days were similar. RALP showed superior sexual outcomes at 1 year, improved urinary outcomes at 18 months, and comparable oncological outcomes at 36 months.

RESUMO

PURPOSE OF REVIEW: The objective of the current article is to promote a literature revision of the relationship between the prevention of intraepithelial neoplasms (PeIN) and invasive penile cancer, and human papillomavirus (HPV) vaccination, aiming to enumerate the pros and cons of immunization. RECENT FINDINGS: The immunization against the HPV is sufficiently safe and many countries have incorporated the vaccine to their immunization calendar. Compared with men, the sampling size and the evidence quality of scientific researches among the female population are more robust. Some randomized and nonrandomized studies suggest that vaccination reduces the incidence of genital warts and no PeIN and penile cancer cases were developed in the vaccinal group. However, 70% of patients can evolve with the neoplasia despite having been immunized and even among HPV infected patients, only 1% will develop cancer. SUMMARY: The studies about vaccination against HPV and prevention on penile cancer are conflicting and the main academic urology societies still have not incorporated vaccination of men in their guidelines. Future studies are necessary to confirm the efficiency and cost-benefit of the vaccine in men to prevent intraepithelial neoplasms and invasive penile cancer.

RESUMO

PURPOSE: Upper-tract urothelial carcinoma (UTUC) is a relatively uncommon disease with limited available evidence on specific topics. The purpose of this article was to review the previous literature to summarize the current knowledge about UTUC epidemiology, diagnosis, preoperative evaluation and prognostic assessment. METHODS: Using MEDLINE, a non-systematic review was performed including articles between January 2000 and February 2016. English language original articles, reviews and editorials were selected based on their clinical relevance. RESULTS: UTUC accounts for 5-10 % of all urothelial cancers, with an increasing incidence. UTUC and bladder cancer share some common risk factors, even if they are two different entities regarding practical, biological and clinical characteristics. Aristolochic acid plays an important role in UTUC pathogenesis in certain regions. It is further estimated that approximately 10 % of UTUC are part of the hereditary non-polyposis colorectal cancer spectrum disease. UTUC diagnosis remains mainly based on imaging and endoscopy, but development of new technologies is rapidly changing the diagnosis algorithm. To help the decision-making process regarding surgical treatment, extent of lymphadenectomy and selection of neoadjuvant systemic therapies, predictive tools based on preoperative patient and tumor characteristics have been developed. CONCLUSIONS: Awareness regarding epidemiology, diagnosis, preoperative evaluation and prognostic assessment changes is essential to correctly diagnose and manage UTUC patients, thereby potentially improving their outcomes.

RESUMO

OBJECTIVE: To identify factors associated with survival after palliative urinary diversion (UD) for patients with malignant ureteric obstruction (MUO) and create a risk-stratification model for treatment decisions. PATIENTS AND METHODS: We prospectively collected clinical and laboratory data for patients who underwent palliative UD by ureteric stenting or percutaneous nephrostomy (PCN) between 1 January 2009 and 1 November 2011 in two tertiary care university hospitals, with a minimum 6-month follow-up. Inclusion criteria were age >18 years and MUO confirmed by computed tomography, ultrasonography or magnetic resonance imaging. Factors related to poor prognosis were identified by Cox univariable and multivariable regression analyses, and a risk stratification model was created by Kaplan-Meier survival estimates at 1, 6 and 12 months, and log-rank tests. RESULTS: The median (range) survival was 144 (0-1084) days for the 208 patients included after UD (58 ureteric stenting, 150 PCN); 164 patients died, 44 (21.2%) during hospitalisation. Overall survival did not differ by UD type (P = 0.216). The number of events related to malignancy (≥4) and Eastern Cooperative Oncology Group (ECOG) index (≥2) were associated with short survival on multivariable analysis. These two risk factors were used to divide patients into three groups by survival type: favourable (no factors), intermediate (one factor) and unfavourable (two factors). The median survival at 1, 6, and 12 months was 94.4%, 57.3% and 44.9% in the favourable group; 78.0%, 36.3%, and 15.5% in the intermediate group; and 46.4%, 14.3%, and 7.1% in the unfavourable group (P < 0.001). CONCLUSIONS: Our stratification model may be useful to determine whether UD is indicated for patients with MUO.

RESUMO

BACKGROUND: Bacillus Calmette-Guerin (BCG) is the standard of care for adjuvant intravesical instillation therapy for intermediate- and high-risk non-muscle invasive bladder cancer (NMIBC) after complete transurethral resection. Increasing evidence suggests that there are marked differences in outcomes according to BCG substrains. BCG-Moreau was recently introduced to the European market to cover the issue of BCG shortage, but there are little data regarding the oncologic efficacy. METHODS: We retrospectively analyzed 295 consecutive patients, who received adjuvant intravesical instillation therapy with BCG-Moreau for intermediate- and high-risk NMIBC between October 2007 and April 2013 at a single institution. The end points of this study were time to first recurrence and progression to muscle-invasive disease. RESULTS: Median age was 66 years (interquartile range 59-74, mean 65.9 years). According to the EAU risk group, 76 patients presented with intermediate-risk and 219 patients with high-risk NMIBC. The 5-year recurrence-free survival and progression-free survival rate was 64.8% (95% CI 52.8-74.4) and 81.4% (95% CI 65.2-90.2), respectively. CONCLUSIONS: BCG-Moreau is an effective substrain for adjuvant instillation therapies of NMIBC, and outcomes appear to be comparable to series using other substrains. During worldwide shortage of BCG-TICE, Connaught and RIVM, BCG-Moreau may serve as an equally effective alternative.

RESUMO

PURPOSE: Statins are cholesterol lowering agents used to prevent cardiovascular disease. Evidence suggests a dichotomous effect of statins with cancer inhibiting and promoting properties. To our knowledge the effect of statins on the prognosis of muscle invasive urothelial carcinoma of the bladder remains uninvestigated to date. We tested the hypothesis that statin use impacts oncological outcomes in patients treated with radical cystectomy for urothelial carcinoma of the bladder. MATERIALS AND METHODS: We retrospectively evaluated the records of 1,502 patients treated with radical cystectomy and pelvic lymphadenectomy without neoadjuvant therapy at a total of 4 institutions. Cox regression models were used to determine the association of statins with disease recurrence and cancer specific mortality. RESULTS: A total of 642 patients (42.7%) were on statins. At a median followup of 34 months 509 patients (33.9%) experienced disease recurrence and 402 (26.8%) had died of urothelial carcinoma of the bladder. Statin users were older (p = 0.003), had a higher body mass index (median 32 vs 28 kg/m(2), p <0.001) and were more likely to have positive soft tissue surgical margins (9% vs 4%, p <0.001). On univariable Cox regression analysis statins, female gender, advanced age, higher body mass index, smoking status, tumor stage, tumor grade, soft tissue surgical margin status, lymphovascular invasion, lymph node metastasis and adjuvant chemotherapy were associated with disease recurrence (p ≤ 0.05) and cancer specific mortality (p ≤ 0.02). On multivariable Cox regression analysis statin use was not associated with either outcome. CONCLUSIONS: Statin users were at higher risk for disease recurrence and cancer specific mortality on univariable but not multivariable analysis. These data do not support modification of statin use in patients with high risk urothelial carcinoma of the bladder who will be treated with radical cystectomy.

RESUMO

PURPOSE: Subclassification of nodal stage may have prognostic value in men with lymph node metastasis at radical prostatectomy. We explored the role of extranodal extension, size of the largest metastatic lymph node and the largest metastasis, and lymph node density as predictors of biochemical recurrence. MATERIALS AND METHODS: We reviewed pathological material from 261 patients with node positive prostate cancer. We examined the predictive value when adding the additional pathology findings to a base model including extraprostatic extension, seminal vesicle invasion, radical prostatectomy Gleason score, prostate specific antigen and number of positive lymph nodes using the Cox proportional hazards regression and Harrell concordance index. RESULTS: The median number of lymph nodes removed was 14 (IQR 9, 20) and the median number of positive lymph nodes was 1 (IQR 1, 2). At a median followup of 4.6 years (IQR 3.2, 6.0) 155 of 261 patients experienced biochemical recurrence. The mean 5-year biochemical recurrence-free survival rate was 39% (95% CI 33-46). Median diameter of the largest metastatic lymph node was 9 mm (IQR 5, 16). On Cox regression radical prostatectomy specimen Gleason score (greater than 7 vs 7 or less), number of positive lymph nodes (3 or greater vs 1 or 2), seminal vesicle invasion and prostate specific antigen were associated with significantly increased risks of biochemical recurrence. On subset analysis metastasis size significantly improved model discrimination (base model Harrell concordance index 0.700 vs 0.655, p = 0.032). CONCLUSIONS: Our study confirms that the number of positive lymph nodes is a predictor of biochemical recurrence in men with node positive disease. The improvement in prognostic value of measuring the metastatic focus warrants further investigation.

RESUMO

INTRODUCTION: Non-metastatic, castration-resistant prostate cancer (nmCRPC) is an important clinical stage of prostate cancer, prior to morbidity and mortality from clinical metastases. In particular, the introduction of novel androgen-receptor signaling inhibitors (ARSi) has changed the therapeutic landscape in nmCRPC. Given recent developments in this field, we update our recommendations for the management of nmCRPC. METHODS: A panel of 51 invited medical oncologists and urologists convened in May of 2021 with the aim of discussing and providing recommendations regarding the most relevant issues concerning staging methods, antineoplastic therapy, osteoclast-targeted therapy, and patient follow-up in nmCRPC. Panel members considered the available evidence and their practical experience to address the 73 multiple-choice questions presented. RESULTS: Key recommendations and findings include the reliance on prostate-specific antigen doubling time for treatment decisions, the absence of a clear preference between conventional and novel (i.e., positron-emission tomography-based) imaging techniques, the increasing role of ARSis in various settings, the general view that ARSis have similar efficacy. Panelists highlighted the slight preference for darolutamide, when safety is of greater concern, and a continued need to develop high-level evidence to guide the intensity of follow-up in this subset of prostate cancer. DISCUSSION: Despite the limitations associated with a consensus panel, the topics addressed are relevant in current practice, and the recommendations can help practicing clinicians to provide state-of-the-art treatment to patients with nmCRPC in Brazil and other countries with similar healthcare settings.

RESUMO

PURPOSE: We determined the frequency and distribution of metastases to pelvic lymph nodes in a contemporary American radical prostatectomy series. MATERIALS AND METHODS: In 642 consecutive patients with clinically localized prostate cancer treated by a single surgeon between 2002 and 2009 pelvic lymph nodes were removed and submitted to the pathologist in separate packets (external iliac, obturator and hypogastric). We assessed the total number of nodes and the number with metastases in each packet. RESULTS: Complete pathological information was available for 427 patients, who had a median of 16 lymph nodes removed. Of the patients 35 (8.2%) had lymph node metastases, including 1.7% with low, 8.6% with intermediate and 23.9% with high risk cancer. Of those with nodal metastases 24 (69%) had positive lymph nodes in only 1 of the 3 areas, including the external iliac in 4 (11%), the obturator in 9 (26%) and the hypogastric in 11 (31%). Only 37% of the patients had positive nodes only in the external iliac area above the obturator nerve while 60% and 49% had at least 1 positive node in the obturator and the hypogastric area, respectively. Of the patients 80% had only 1 (49%) or 2 (31%) positive nodes. CONCLUSIONS: In contemporary American patients with clinically localized prostate cancer lymph node metastases were found more often and frequently exclusively in the obturator and hypogastric areas than in the external iliac area. Pelvic lymph node dissection limited to the external iliac area above the obturator nerve would identify and remove lymph node metastases in only a third of the patients with positive nodes found at full pelvic lymph node dissection.

RESUMO

OBJECTIVE: To create a preoperative multivariable model to identify patients at risk of muscle-invasive (pT2+) upper tract urothelial carcinoma (UTUC) and/or non-organ confined (pT3+ or N+) UTUC (NOC-UTUC) who potentially could benefit from radical nephroureterectomy (RNU), neoadjuvant chemotherapy and/or an extended lymph node dissection. PATIENTS AND METHODS: We retrospectively analysed data from 324 consecutive patients treated with RNU between 1995 and 2008 at a tertiary cancer centre. Patients with muscle-invasive bladder cancer were excluded, resulting in 274 patients for analysis. Logistic regression models were used to predict pT2+ and NOC-UTUC. Pre-specified predictors included local invasion (i.e. parenchymal, renal sinus fat, or periureteric) on imaging, hydronephrosis on imaging, high-grade tumours on ureteroscopy, and tumour location on ureteroscopy. Predictive accuracy was measured by the area under the curve (AUC). RESULTS: The median follow-up for patients without disease recurrence or death was 4.2 years. Overall, 49% of the patients had pT2+, and 30% had NOC-UTUC at the time of RNU. In the multivariable analysis, only local invasion on imaging and ureteroscopy high grade were significantly associated with pathological stage. AUC to predict pT2+ and NOC-UTUC were 0.71 and 0.70, respectively. CONCLUSIONS: We designed a preoperative prediction model for pT2+ and NOC-UTUC, based on readily available imaging and ureteroscopic grade. Further research is needed to determine whether use of this prediction model to select patients for conservative management vs RNU, neoadjuvant chemotherapy, and/or extended lymphadenectomy will improve patient outcomes.

RESUMO

PURPOSES: To describe the differential tissue expression of tumor-associated trypsin inhibitor (TATI) in normal bladder urothelium, primary urothelial carcinoma of the bladder (UCB) and metastatic UCB and to assess the association of TATI expression with molecular markers commonly altered in UCB and clinical outcomes after radical cystectomy. METHODS: Slides from eight cystectomy patients without cancer, 191 radical cystectomy patients, 20 lymph nodes without metastasis and 40 lymph nodes with UCB were stained. Tissue expression of TATI, cyclin E1, cyclin D1, p53, p21, p27, pRB, Ki-67, Bcl-2, Caspase-3, Survivin and Cyclooxigenase-2 was measured in a tissue microarray. Cancer-specific and recurrence-free survival after radical cystectomy was recorded. RESULTS: TATI was expressed in 100% of patients without cancer, while 71% of radical cystectomy specimens and 90% of lymph node metastases exhibited decreased or no TATI expression. In radical cystectomy specimens, TATI expression decreased with advancing pathologic stage (P < 0.001) and lymphovascular invasion (P = 0.055). In univariate analyses, but not in multivariable Cox proportional hazard regression analyses, decreased TATI expression was associated with increased probability of tumor recurrence and cancer-specific mortality. Decreased TATI expression was correlated with altered expression of Cyclooxigenase-2 (P = 0.005), p21 (P = 0.035) and Ki-67 (P = 0.004). CONCLUSIONS: We found that normal urothelium expresses TATI and that TATI expression decreases with advancing tumor stage. While there was no prognostic benefit to TATI when adjusted for standard clinicopathologic features, it seems to play an important biologic role in UCB pathogenesis and invasion. Its association with markers involved in the cell cycle, proliferation and inflammation serves as hypothesis for molecular interactions.

RESUMO

BACKGROUND: Platinum-based neoadjuvant chemotherapy (NAC) in muscle-invasive urothelial bladder cancer (MIBC) has been adopted as a standard of care related to better survival outcomes. However, there is a considerable number of patients who do not respond, experiencing toxicity and delay in the surgical treatment. Our aim is to find biomarkers of response that could be easily adopted in the clinical practice. METHODS: Between January 2009 and July 2016, 52 patients with MIBC were submitted to radical cystectomy after NAC. A tissue microarray containing 25 cases, who met the inclusion criteria was built for immunohistochemical analysis of Cytokeratins 5/6, 7, and 20, GATA3, Her2, EGFR, p63, p53, Carbonic-anhydrase IX (CAIX), MLH1, MSH2, MSH6, and PMS2. The surgery was performed in a mean time of 58.7 (± 21) days after the end of the NAC. Fisher's exact test was used to analyze the relationship between response (≤pT1) and histopathological and immunohistochemical results and Kaplan-Meier curves were designed for survival analysis. RESULTS: Ten (40.0%) patients presented response to NAC. Histological variants of the urothelial carcinoma characterized by squamous, sarcomatous/rhabdoid, plasmacytoid, and micropapillary was present in 36.0% and none responded to NAC (P = .002). CAIX was expressed by 53.3% and none responded to NAC (P= .005). Lymph-node metastasis, divergent differentiation, and expression of cytokeratin 5/6 were related to short cancer specific survival. CONCLUSION: Histological variants and CAIX immune-expression are biomarkers of nonresponse to NAC of MIBC, and might be easily used in the clinical practice to select patients to be submitted to surgery upfront.

RESUMO

BACKGROUND: The HoLERBT (Holmium Laser En-bloc Resection of Bladder Tumors) has emerged as an alternative to classical TURBT (Transurethral Resection of Bladder Tumor). Recent randomized trial and meta-analysis corroborate with the benefits in pathological analysis, perioperative and long-term oncological outcomes.1-3 However, the treatment of large tumors and the technique of extraction from the bladder is a problem to be overcome.1,4 OBJECTIVE: To describe the laser resection of bladder tumors and demonstrate the feasibility of this procedure even for large tumors throughout a series of cases. It is also discussed the quality of the histopathological analysis. METHODS: A series of 8 cases randomized selected to be the pilot for a trial comparing TURBT and HoLERBT in large tumors (>3 cm) in progress was analyzed (Brazilian Registry of Clinical Trials number RBR-67npwrk). The perioperative data and 1-year outcomes were assessed and the quality of histopathological analysis after morcellation was evaluated in terms of histopathology, grade, and stage. The entire procedure of one case is shown in a step-by-step video. RESULTS: The mean follow-up was 12.6 months. The mean age was 59.6 (42-85) years, and the mean tumor size was 4.7 (4-8) cm. All the resections were En-bloc. There were 2 cases of NMIBC, 4 cases of MIBC, 1 paraganglioma, and 1 adenocarcinoma. The histopathological analysis confirmed the presence of detrusor muscle layer and accurate diagnosis and staging in all cases (100%). There were no perioperative Clavien-Dindo > 1 complications, no blood transfusion, and no bladder perforations. The histopathology analysis reveals excellent quality without artifacts of fulguration. CONCLUSION: The holmium laser resection followed by morcellation of large bladder tumors is a feasible procedure. No complications occurred in our series of cases and all cases provided excellent material for histopathological analysis.

RESUMO

PURPOSE: We analyzed characteristics in patients with recurrent renal cell carcinoma 5 years or later after nephrectomy and determined predictors of survival after recurrence. MATERIALS AND METHODS: From July 1989 to October 2008 at total of 2,368 nephrectomies were done for clinically localized, unilateral renal cell carcinoma at our institution. Of 256 patients with disease recurrence 44 had recurrence 5 years or more after nephrectomy. We compared clinicopathological characteristics in patients with disease recurrence before vs after 5 years. Survival from time of recurrence was assessed based on Memorial Sloan-Kettering Cancer Center risk score, symptoms at recurrence, metastasectomy, tumor diameter, and recurrence stage and site. RESULTS: Patients with late recurrence tended to have fewer symptoms at presentation, smaller tumors (median 8.5 vs 7 cm) and less aggressive disease (pT1 in 18% vs 39%). Median overall survival was 6.1 years from time of recurrence. Five-year actuarial survival was 85% in 28 patients at favorable risk and 14% in 10 at intermediate risk (log rank p <0.001). The 5-year estimated overall survival rate was 72% in 31 patients with incidentally detected recurrence and 39% in 11 with symptoms at recurrence (log rank p = 0.01). CONCLUSIONS: Data suggest that patients with cancer recurrence 5 years after nephrectomy are at favorable risk and have long-term median survival. A favorable Memorial Sloan-Kettering Cancer Center risk score and absent symptoms related to metastasis are associated with longer survival in these patients.

RESUMO

OBJECTIVE: • To evaluate feasibility, safety and oncological efficacy of salvage laparoscopic radical prostatectomy for pathology-proven biochemical recurrence after primary radiation therapy or cryotherapy for prostate cancer. MATERIALS AND METHODS: • This retrospective pilot study examined 15 patients from 2004 to 2010 with biochemical recurrence after external beam radiation therapy (N= 8), brachytherapy (N= 6) or cryotherapy (N= 1). • Patients were treated with salvage laparoscopic radical prostatectomy (11 conventional, four robotic-assisted) with bilateral pelvic dissection. RESULTS: • Median duration of surgery was 235 min. None of the following occurred: conversion to open surgery, transfusion, urethrovesical stenosis or perioperative or postoperative mortality. One patient presented with a rectal injury, repaired using uninterrupted sutures and a colostomy. One patient had anastomotic leak treated with prolonged Foley catheterization. • Pathological stage was pT2a in three, pT2b in three, pT3a in four, pT3b in three and pT4 in two patients; two patients had nodal metastasis. Within an 8-month median follow-up, 11 patients were disease-free and three had persistent postoperative prostate-specific antigen (PSA) elevation; the remaining patient experienced PSA recurrence after 21 months. • Seven patients achieved continence (no pads) by 8.4 months (median), one patient manifested severe incontinence corrected by implanting an artificial sphincter, and seven patients with a 12.6-month mean follow-up continued to need one or two pads per day. • Erectile dysfunction was present in five patients before surgery and in 14 patients after surgery. CONCLUSION: • Salvage laparoscopic radical prostatectomy seems to offer a safe therapeutic alternative for patients failing primary radiation or cryotherapy. However, larger studies with longer-term data are required.

RESUMO

PURPOSE: The learning curve is a period in which the surgical procedure is performed with difficulty and slowness, leading to a higher risk of complications and reduced effectiveness due the surgeon's inexperience. We sought to analyze the residents' learning curve for open radical prostatectomy (RP) in a training program. MATERIALS AND METHODS: We conducted a prospective study from June 2006 to January 2008 in the academic environment of the University of Sao Paulo. Five residents operated on 184 patients during a four-month rotation in the urologic oncology division, mentored by the same physician assistants. We performed sequential analyses according to the number of surgeries, as follows: ≤ 10, 11 to 19, 20 to 28, and ≥ 29. RESULTS: The residents performed an average of 37 RP each. The average psa was 9.3 ng/mL and clinical stage T1c in 71% of the patients. The pathological stage was pT2 (73%), pT3 (23%), pT4 (4%), and 46% of the patients had a Gleason score 7 or higher. In all surgeries, the average operative time and estimated blood loss was 140 minutes and 488 mL. Overall, 7.2% of patients required blood transfusion, and 23% had positive surgical margins. CONCLUSION: During the initial RP learning curve, we found a significant reduction in the operative time; blood transfusion during the procedures and positive surgical margin rate were stable in our series.

RESUMO

Radical prostatectomy is a commonly adopted treatment for localized/locally advanced prostate cancer in men with a life expectancy of ten years or more. Robotic-assisted radical prostatectomy (RARP) is comparable to open radical prostatectomy on cancer control and complication rates; however, new evidence suggests that RARP may have better functional outcomes, especially with respect to urinary incontinence and erectile dysfunction. Some of the surgical steps of RARP are not adequately described in published literature and, as such, may have an impact on the final outcomes of the procedure. We organized a Brazilian experts' panel to evaluate best practices in RARP. The confection of the recommendations broadly involved: selection of the experts; establishment of working groups; systematic review of the literature and elaboration of a questionnaire; and construction of the final text with the approval of all participants. The participants reviewed the publications in English from December 2019 to February 2020. A one-round Delphi technique was employed in 188 questions. Five reviewers worked on the final recommendations using consensual and non-consensual questions. We found 59.9% of questions with greater than 70% agreement that were considered consensual. Non-consensual questions were reported according to the responses. The recommendations were based on evidence-based literature and individual perceptions adapted to the Brazilian reality, although some issues remain controversial. We believe that these recommendations may help urologists involved in RARP and hope that future discussions on this surgical procedure may evolve over the ensuing years.

RESUMO

PURPOSE: To generate and present the survey results on critical issues relevant to screening, diagnosis, and staging tools for prostate cancer (PCa) focused on developing countries. METHODS: A total of 36 of 300 questions concern the main areas of interest of this paper: (1) screening, (2) diagnosis, and (3) staging for various risk levels of PCa in developing countries. A panel of 99 international multidisciplinary cancer experts voted on these questions to create recommendations for screening, diagnosing, and staging tools for PCa in areas of limited resources discussed in this manuscript. RESULTS: The panel voted publicly but anonymously on the predefined questions. Each question was deemed consensus if 75% or more of the full panel had selected a particular answer. These answers are based on panelist opinion not a literature review or meta-analysis. For questions that refer to an area of limited resources, the recommendations consider cost-effectiveness and the possible therapies with easier and greater access. Each question had five to seven relevant answers including two nonanswers. The results were tabulated in real time. CONCLUSION: The voting results and recommendations presented in this document can be used by physicians to support the screening, diagnosis, and staging of PCa in areas of limited resources. Individual clinical decision making should be supported by available data; however, as guidelines for screening, diagnosis, and staging of PCa in developing countries have not been developed, this document will serve as a point of reference when confronted with this disease.

RESUMO

PURPOSE: The number of centers performing robotic assisted radical cystectomy has recently increased, spurring greater concerns about oncological outcomes. In this review we summarize the most comprehensive articles published on the oncological outcomes of laparoscopic assisted, robotic assisted and open radical cystectomy. MATERIALS AND METHODS: A MEDLINE/PubMed literature search was conducted in March 2009 to review English language articles published from 1998 onward. Of 217 selected articles on the 3 techniques 19 studies were selected for this review. RESULTS: The laparoscopic series reported recurrence-free survival rates in the range of 83% to 85% at 1 to 2 years and 60% to 77% at 2 to 3 years, while the robotic assisted studies reported recurrence-free survival rates of 86% to 91% at 1 to 2 years. Large open surgery studies showed 62% to 68% recurrence-free survival at 5 years and 50% to 60% at 10 years, with overall survival of 59% to 66% at 5 years and 37% to 43% at 10 years. Overall survival in the laparoscopic cohorts was 90% to 100% at 1 to 2 years and 50% to 87% at 2 to 3 years. Publications reporting robotic cases demonstrated a 90% to 96% overall survival in 1 to 2 years of followup. CONCLUSIONS: Despite the surge of centers adopting minimally invasive approaches for radical cystectomy, the long-term effectiveness of these techniques has not yet been proven. This review of recent and landmark articles on open and minimally invasive procedures emphasizes the need for prospective controlled studies and long-term followup data to determine the proper use of laparoscopic and robotic assisted techniques in bladder cancer surgery.
