RESUMO
Importance: No data exist on time to recovery of patient-reported and performance-related measures of functional independence after radical cystectomy (open or robotic). Objective: To determine recovery of functional independence after radical cystectomy and whether robot-assisted radical cystectomy (RARC) is associated with any advantage over open procedures. Design, Setting, and Participants: Data for this secondary analysis from the RAZOR (Randomized Open vs Robotic Cystectomy) trial were used. RAZOR was a phase 3 multicenter noninferiority trial across 15 academic medical centers in the US from July 1, 2011, to November 18, 2014, with a median follow-up of 2 years. Participants included the per-protocol population (n = 302). Data were analyzed from February 1, 2017, to May 1, 2021. Interventions: Robot-assisted radical cystectomy or open radical cystectomy (ORC). Main Outcomes and Measures: Patient-reported (activities of daily living [ADL] and independent ADL [iADL]) and performance-related (hand grip strength [HGS] and Timed Up & Go walking test [TUGWT]) measures of independence were assessed. Patterns of postoperative recovery for the entire cohort and comparisons between RARC and ORC were performed. Exploratory analyses to assess measures of independence across diversion type and to determine whether baseline impairments were associated with 90-day complications or 1-year mortality were performed. Findings: Of the 302 patients included in the analysis (254 men [84.1%]; mean [SD] age at consent, 68.0 [9.7] years), 150 underwent RARC and 152 underwent ORC. Baseline characteristics were similar in both groups. For the entire cohort, ADL, iADL, and TUGWT recovered to baseline by 3 postoperative months, whereas HGS recovered by 6 months. There was no difference between RARC and ORC for ADL, iADL, TUGWT, or HGS scores at any time. Activities of daily living recovered 1 month after RARC (mean estimated score, 7.7 [95% CI, 7.3-8.0]) vs 3 months after ORC (mean estimated score, 7.5 [95% CI, 7.2-7.8]). Hand grip strength recovered by 3 months after RARC (mean estimated HGS, 29.0 [95% CI, 26.3-31.7] kg) vs 6 months after ORC (mean estimated HGS, 31.2 [95% CI, 28.8-34.2] kg). In the RARC group, 32 of 90 patients (35.6%) showed a recovery in HGS at 3 months vs 32 of 88 (36.4%) in the ORC group (P = .91), indicating a rejection of the primary study hypothesis for HGS. Independent ADL and TUGWT recovered in 3 months for both approaches. Hand grip strength showed earlier recovery in patients undergoing continent urinary diversion (mean HGS at 3 months, 31.3 [95% CI, 27.7-34.8] vs 33.9 [95% CI, 30.5-37.3] at baseline; P = .09) than noncontinent urinary diversion (mean HGS at 6 months, 27.4 [95% CI, 24.9-30.0] vs 29.5 [95% CI, 27.2-31.9] kg at baseline; P = .02), with no differences in other parameters. Baseline impairments in any parameter were not associated with 90-day complications or 1-year mortality. Conclusions and Relevance: The results of this secondary analysis suggest that patients require 3 to 6 months to recover baseline levels after radical cystectomy irrespective of surgical approach. These data will be invaluable in patient counseling and preparation. Hand grip strength and ADL tended to recover to baseline earlier after RARC; however, there was no difference in the percentage of patients recovering when compared with ORC. Further study is needed to assess the clinical significance of these findings. Trial Registration: ClinicalTrials.gov Identifier: NCT01157676.

Focal therapy (FT) has recently gained popularity for the treatment of localized prostate cancer (PCa). FT achieves cancer control by targeting the lesions or the regions of the cancer and avoids damage to the surrounding tissues thus minimizing side effects which are common to the radical treatment, such as urinary continence and sexual function, and bowel-related side effects. Various ablative methods are used to deliver energy to the cancerous tissue. We review the different modalities of treatment and the current state of FT for PCa.
RESUMO
The cornerstone for diagnosis and treatment of bladder and upper tract urothelial carcinoma involves surgery. Transurethral resection of bladder tumors forms the basis of further management. Radical cystectomy for invasive bladder carcinoma provides good oncologic outcomes. However, it can be a morbid procedure, and advances such as minimally invasive surgery and early recovery after surgery need to be incorporated into routine practice. Diagnostic ureteroscopy for upper tract carcinoma is needed in cases of doubt after cytology and imaging studies. Low-risk cancers can be managed with conservative endoscopic surgery without compromising oncological outcomes; however, high-risk disease necessitates radical nephroureterectomy.

PURPOSE: We evaluated health related quality of life following robotic and open radical cystectomy as a treatment for bladder cancer. MATERIALS AND METHODS: Using the Randomized Open versus Robotic Cystectomy (RAZOR) trial population we assessed health related quality of life by using the Functional Assessment of Cancer Therapy (FACT)-Vanderbilt Cystectomy Index and the Short Form 8 Health Survey (SF-8) at baseline, 3 and 6 months postoperatively. The primary objective was to assess the impact of surgical approach on health related quality of life. As an exploratory analysis we assessed the impact of urinary diversion type on health related quality of life. RESULTS: Analyses were performed in subsets of the per-protocol population of 302 patients. There was no statistically significant difference between the mean scores by surgical approach at any time point for any FACT-Vanderbilt Cystectomy Index subscale or composite score (p >0.05). The emotional well-being score increased over time in both surgical arms. Patients in the open arm showed significantly better SF-8 sores in the physical and mental summary scores at 6 months compared to baseline (p <0.05). Continent diversion (versus noncontinent) was associated with worse FACT-bladder-cystectomy score at 3 (p <0.01) but not at 6 months, and the SF-8 physical component was better in continent-diversion patients at 6 months (p=0.019). CONCLUSIONS: Our data suggests lack of significant differences in the health related quality of life in robotic and open cystectomies. As robotic procedures become more widespread it is important to discuss this finding during counseling.

PURPOSE: We report short-term outcomes of focal high intensity focused ultrasound use for primary treatment of localized prostate cancer. MATERIALS AND METHODS: Single-center prospectively collected data on patients with prostate cancer who underwent primary focal high intensity focused ultrasound from January 2016 to July 2018 were included. All patients underwent a 12-core biopsy with magnetic resonance imaging-ultrasound fusion biopsy depending on the presence of targetable lesions. Any Grade Group was allowed, however only patients with localized disease were included. The primary outcome was oncologic control, defined as negative followup in-field biopsy of treated cancer. Prostate specific antigen, Sexual Health Inventory for Men, International Prostate Symptom Score and Expanded Prostate Cancer Index Composite domain scores were assessed 3-monthly till 12 months. Biopsy was performed at 6 or 12 months for high or low/intermediate risk cancer, respectively. RESULTS: Fifty-two patients with minimum followup of 12 months were included in the study. The majority of patients (67%) had cancer Grade Group 2 or greater. Fifteen patients (28.8%) underwent complete transurethral prostate resection/holmium laser enucleation of prostate procedure for debulking large prostates to avoid postoperative urinary retention. Among 30 (58%) patients who underwent followup biopsies, 25 (83%) had negative in-field biopsy results and 4 (13%) had de-novo positive out-of-field biopsy. Only 5 major complications (all grade III) in 4 patients were noted. Urinary symptoms returned to near baseline questionnaire scores within 3-6 months. Sexual function returned to baseline at 12 months. CONCLUSIONS: Focal high intensity focused ultrasound is a safe and effective treatment for patients with localized clinically significant prostate cancer with acceptable short-term oncologic and functional outcomes. The complications are minimal and patient selection is essential. Short-term oncologic outcomes are promising but longer followup is required to establish long-term oncologic outcomes.

PURPOSE: The RAZOR (Randomized Open versus Robotic Cystectomy) trial revealed noninferior 2-year progression-free survival for robotic radical cystectomy. This update was performed with extended followup for 3 years to determine potential differences between the approaches. We also report 3-year overall survival and sought to identify factors predicting recurrence, and progression-free and overall survival. MATERIALS AND METHODS: We analyzed the per protocol population of 302 patients from the RAZOR study. Cumulative recurrence was estimated using nonbladder cancer death as the competing risk event and the Gray test was applied to assess significance in differences. Progression-free survival and overall survival were estimated by the Kaplan-Meier method and compared with the log rank test. Predictors of outcomes were determined by Cox proportional hazard analysis. RESULTS: Estimated progression-free survival at 36 months was 68.4% (95% CI 60.1-75.3) and 65.4% (95% CI 56.8-72.7) in the robotic and open groups, respectively (p=0.600). At 36 months overall survival was 73.9% (95% CI 65.5-80.5) and 68.5% (95% CI 59.8-75.7) in the robotic and open groups, respectively (p=0.334). There was no significant difference in the cumulative incidence rates of recurrence (p=0.802). Patient age greater than 70 years, poor performance status and major complications were significant predictors of 36-month progression-free survival. Stage and positive margins were significant predictors of recurrence, and progression-free and overall survival. Surgical approach was not a significant predictor of any outcome. CONCLUSIONS: This analysis showed no difference in recurrence, 3-year progression-free survival or 3-year overall survival for robotic vs open radical cystectomy. It provides important prospective data on the oncologic efficacy of robotic radical cystectomy and high level data for patient counseling.

RESUMO
INTRODUCTION: To assess the secondary sequence rule in The Prostate Imaging Reporting Data System (PI-RADS) version 2 by comparing the detection of Grade group 1+ (GG1+) and 2+ (GG2+) cancers in PI-RADS 3, an upgraded PI-RADS 4, and true (non-upgraded) PI-RADS 4 targets. MATERIALS AND METHODS: We analyzed a total of 589 lesions scored as PI-RADS 3 or 4 obtained from 434 men who underwent mpMRI-US fusion biopsy from September 2015 to November 2017 for evaluation of GG1+ and GG2+ prostate cancer. PI-RADS 4 lesions were differentiated into those that were 'upgraded' to PI-RADS 4 based on the secondary sequence and those that were 'true' PI-RADS 4 based on the dominant sequence. RESULTS: The odds of detecting a GG2+ cancer was significantly higher for an upgraded 4 (peripheral zone (PZ): OR 5.06, 95%CI 2.04-12.54, p < 0.001, transitional zone (TZ): OR 3.08, 95%CI 1.04-9.08, p = 0.042) and true 4 (PZ: OR 5.82, 95%CI 3.10-10.94, p < 0.0001, TZ: OR 2.43, 95%CI 1.14-5.18, p = 0.022) lesions compared to PI-RADS 3 lesions. Additionally, we found no difference in the odds of detecting a GG2+ prostate cancer between a true PI-RADS 4 (OR 1.15, 95%CI 0.49-2.71 p = 0.746) and upgraded 4 (referent) in the PZ. Similar non-significance was noted between true 4 (OR 0.79, 95%CI 0.26-2.38 p = 0.674) and upgraded 4 lesions in the TZ for detection of GG2+ cancers. CONCLUSIONS: Upgraded PI-RADS 4 and true 4 targets have a higher odds of detecting GG1+ and GG2+ compared to PI-RADS 3 in the PZ and TZ. Our findings validate the revised scoring system for PI-RADS.

Renal cell carcinoma, particularly the most common clear cell type, is one of the most aggressive of urological cancers with significant risk of metastatic spread. It also has a propensity for venotropism with a proportion of tumors developing thrombi up to the right atrium. The response with newly adopted targeted therapy has been considered to be in the evolutionary stage with no clear role with respect to debulking or reducing the size of the inferior vena cava (IVC) thrombus. We describe a case of a right-sided metastatic RCC with Level IV thrombus initially managed with Pazopanib followed by Nivolumab and Adalimumab followed by cytoreductive nephrectomy and IVC thrombectomy in the post-targeted therapy setting with complete curative response.
RESUMO
BACKGROUND: Partial nephrectomy is widely used for surgical management of small renal masses. Use of robotic (RPN) versus open partial nephrectomy (OPN) among various populations is not well characterized. OBJECTIVE: To analyze trends in utilization of RPN and disparities that may be associated with this procedure for management of cT1 renal masses in the USA. DESIGN, SETTING, AND PARTICIPANTS: Patients who underwent RPN or OPN for clinical stage T1N0M0 renal masses in the USA from 2010 to 2013 were identified in the National Cancer Data Base. A total of 23 154 patients fulfilled the inclusion criteria. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Univariable and multivariable logistic regression analyses were performed to evaluate differences in receiving RPN or OPN across various patient groups. RESULTS AND LIMITATIONS: Utilization of RPN increased from 41% in 2010 to 63% in 2013. Black patients (adjusted odds ratio [aOR] 0.91, 95% confidence interval [CI] 0.84-0.98) and Hispanic patients (aOR 0.85, 95% CI 0.77-0.95) were less likely to undergo RPN. RPN was less likely to be performed in rural counties (aOR 0.80, 95% CI 0.66-0.98) and in patients with no insurance (aOR 0.52, 95% CI 0.44-0.61) or patients covered by Medicaid (aOR 0.81, 95% CI 0.73-0.90). There was no significant difference in RPN utilization between academic and non-academic facilities. Patients with higher clinical stage (aOR 0.58, 95% CI 0.55-0.62) and comorbidities (aOR 0.79, 95% CI 0.71-0.88) were also less likely to undergo RPN. CONCLUSIONS: Utilization of RPN has continued to increase over time; however, there are significant disparities in its utilization according to race and socioeconomic status. Black and Hispanic patients and patients in rural communities and with limited insurance were more likely to be treated with OPN instead of RPN. PATIENT SUMMARY: The use of robotic surgery in partial nephrectomy for management of small renal masses has increased over time. We found a significant disparity across different racial and socioeconomic groups in use of robotic partial nephrectomy compared to open surgery. Patients living in rural areas, with limited insurance, and multiple medical comorbidities were more likely to undergo open than robotic partial nephrectomy.

INTRODUCTION: Minimally invasive nephroureterectomy (MINU) and open nephroureterectomy (ONU) have similar oncological outcomes for treatment of upper tract urothelial carcinoma (UTUC). We investigated perioperative outcomes and predictors of complications associated with MINU and ONU. MATERIAL AND METHODS: Using the National Surgical Quality Improvement Program (NSQIP) database, 912 patients were identified that underwent radical nephroureterectomy for UTUC between 2005 and 2013. Logistic regression and contingency table methods used preoperative covariates to predict rates of major (Clavien-Dindo grade ≥ 3) and 16 common perioperative complications. Additional comparisons between treatment groups were performed using unpaired t-tests, Wilcoxon rank-sum tests, or Fisher's Exact tests. P values were adjusted to maintain an experiment-wise p < 0.05. RESULTS: A total of 625 (69%) and 287 (31%) patients underwent MINU and ONU, respectively. ONU was associated with a higher rate of major complications (OR: 2.5, CI: 1.2-5.1, p < 0.03). The incidence of pulmonary embolism (bias adjusted OR: 24, CI: 1.3-441, p < 0.003), postoperative pneumonia (OR: 4.9, CI: 1.7-16, p < 0.0016), and transfusion (OR: 2.7, CI: 1.8-4.0, p < 0.0001) was higher for ONU compared to MINU. There were no significant differences in the incidence of other complications. MINU took longer on average (median 223 versus 213 mins, p < 0.02). Time to discharge was longer for ONU (median 5 versus 4 days, p < 0.0001). No other covariates were independent predictors of major complications regardless of surgical approach. CONCLUSIONS: Occurrence of major complications were higher for ONU compared to MINU. These data suggest that MINU is an acceptable surgical option with lower morbidity compared to ONU for the management of UTUC.

BACKGROUND: Non-Hispanic Black (NHB) men are at an increased risk for aggressive prostate cancer (PCa), making active surveillance (AS) potentially less optimal in this population. This concern has not been explored in other minority populations-specifically, Hispanic/Latino men. We recently found that Mexican-American men demonstrate an increased risk of PCa-specific mortality, and we hypothesized that they may also be at risk for an adverse outcome on AS. METHODS: Using the Surveillance, Epidemiology, and End Results (SEER) program, we extracted a population-based cohort of men diagnosed from 2004 to 2013 with localized or regional PCa, who had ≤2 cores of only Grade Group (GG) 1 cancer, and underwent radical prostatectomy (RP) with available biopsy and surgical pathology results. We measured discovery of high-risk PCa at RP and collected socioeconomic status (SES) data across different racial/ethnic groups. We defined aggressive tumors as either an upgrade to GG 3 or higher (GG3+) cancer or non-organ-confined disease (≥pT3a or N1). Univariate and multivariate logistic regression models were developed to assess the association between racial/ethnic categories and the previously mentioned adverse oncologic outcomes both with and without adjusting for SES factors. RESULTS: NHB and Mexican-American men were significantly more likely to have aggressive PCa, following RP. In multivariable logistic regression adjusting for SES factors and relative to non-Hispanic White (NHW) men, Mexican-American men had at increased odds of upgrading to GG3+ (OR 1.67; 95% CI [1.00-2.90]). NHB men were more likely to have non-organ-confined disease (OR 1.34; 95% CI [1.06-1.69]), while Mexican-American men had a similar risk to NHW men. CONCLUSION: Among individuals with low-risk PCa and eligible for AS, Mexican-American and NHB men are at an increased risk of harboring more aggressive disease at RP. This novel finding among Mexican-Americans deserves further evaluation.

BACKGROUND: Radical cystectomy is the surgical standard for invasive bladder cancer. Robot-assisted cystectomy has been proposed to provide similar oncological outcomes with lower morbidity. We aimed to compare progression-free survival in patients with bladder cancer treated with open cystectomy and robot-assisted cystectomy. METHODS: The RAZOR study is a randomised, open-label, non-inferiority, phase 3 trial done in 15 medical centres in the USA. Eligible participants (aged ≥18 years) had biopsy-proven clinical stage T1-T4, N0-N1, M0 bladder cancer or refractory carcinoma in situ. Individuals who had previously had open abdominal or pelvic surgery, or who had any pre-existing health conditions that would preclude safe initiation or maintenance of pneumoperitoneum were excluded. Patients were centrally assigned (1:1) via a web-based system, with block randomisation by institution, stratified by type of urinary diversion, clinical T stage, and Eastern Cooperative Oncology Group performance status, to receive robot-assisted radical cystectomy or open radical cystectomy with extracorporeal urinary diversion. Treatment allocation was only masked from pathologists. The primary endpoint was 2-year progression-free survival, with non-inferiority established if the lower bound of the one-sided 97·5% CI for the treatment difference (robotic cystectomy minus open cystectomy) was greater than -15 percentage points. The primary analysis was done in the per-protocol population. Safety was assessed in the same population. This trial is registered with ClinicalTrials.gov, number NCT01157676. FINDINGS: Between July 1, 2011, and Nov 18, 2014, 350 participants were randomly assigned to treatment. The intended treatment was robotic cystectomy in 176 patients and open cystectomy in 174 patients. 17 (10%) of 176 patients in the robotic cystectomy group did not have surgery and nine (5%) patients had a different surgery to that they were assigned. 21 (12%) of 174 patients in the open cystectomy group did not have surgery and one (1%) patient had robotic cystectomy instead of open cystectomy. Thus, 302 patients (150 in the robotic cystectomy group and 152 in the open cystectomy group) were included in the per-protocol analysis set. 2-year progression-free survival was 72·3% (95% CI 64·3 to 78·8) in the robotic cystectomy group and 71·6% (95% CI 63·6 to 78·2) in the open cystectomy group (difference 0·7%, 95% CI -9·6% to 10·9%; pnon-inferiority=0·001), indicating non-inferiority of robotic cystectomy. Adverse events occurred in 101 (67%) of 150 patients in the robotic cystectomy group and 105 (69%) of 152 patients in the open cystectomy group. The most common adverse events were urinary tract infection (53 [35%] in the robotic cystectomy group vs 39 [26%] in the open cystectomy group) and postoperative ileus (33 [22%] in the robotic cystectomy group vs 31 [20%] in the open cystectomy group). INTERPRETATION: In patients with bladder cancer, robotic cystectomy was non-inferior to open cystectomy for 2-year progression-free survival. Increased adoption of robotic surgery in clinical practice should lead to future randomised trials to assess the true value of this surgical approach in patients with other cancer types.

Traditional prostate imaging is fairly limited, and only a few imaging modalities have been used for this purpose. Until today, grey scale ultrasound was the most widely used method for the characterization of the prostatic gland, however its limitations for prostate cancer (PCa) detection are well known and hence ultrasound is primarily used to localize the prostate and facilitate template prostate biopsies. In the past decade, multiparametric magnetic resonance imaging (mpMRI) of the prostate has emerged as a promising tool for the detection of PCa. Evidence has shown the value of mpMRI in the active surveillance (AS) population, given its ability to detect more aggressive disease, with data building up and supporting its use for the selection of patients suitable for surveillance. Additionally, mpMRI targeted biopsies have shown an improved detection rate of aggressive PCa when compared to regular transrectal ultrasound (TRUS) guided biopsies. Current data supports the use of mpMRI in patients considered for AS for reclassification purposes; with a negative mpMRI indicating a decreased risk of reclassification. However, a percentage of patients with negative imaging or low suspicion lesions can experience reclassification, highlighting the importance of repeat confirmatory biopsy regardless of mpMRI findings. At present, no robust data is available to recommend the substitution of regular biopsies with mpMRI in the follow-up of patients on AS and efforts are being made to determine the role of integrating genomic markers with imaging with the objective of minimizing the need of biopsies during the follow up period.
RESUMO
OBJECTIVE: To demonstrate a step-by-step approach to the use of the operating microscope for onco-testicular sperm extraction. DESIGN: Video presentation. SETTING: University hospital. PATIENT(S): A 34-year-old man (status post right orchiectomy at another institution for pT3 pure seminoma with negative preoperative tumor markers) was referred for contralateral orchiectomy for multifocal left testis mass and fertility preservation. A postoperative semen analysis for attempted cryopreservation of ejaculated semen identified azoospermia. INTERVENTION(S): Left radical orchiectomy, left microsurgical onco-testicular sperm extraction (TESE). MAIN OUTCOME MEASURE(S): Intraoperative technique with commentary highlighting tips for successful fertility preservation via microsurgical onco-TESE. Discussion of alternatives. RESULT(S): This video provides a step-by-step guide to microsurgical onco-TESE coordinated with radical orchiectomy for testis cancer as a means of fertility preservation in an azoospermic patient. Preoperative imaging with scrotal ultrasound can serve as a useful guide for targeting microdissection to areas of normal testicular parenchyma for extraction of seminiferous tubules likely to host normal spermatogenesis. This patient had successful recovery and cryopreservation of abundant testicular sperm following targeted ex-vivo testicular microdissection. CONCLUSION(S): Microsurgical onco-TESE may be offered to azoospermic patients when undergoing orchiectomy for testis cancer. Use of preoperative imaging and the surgical microscope guide surgical dissection and optimize sperm recovery.

PURPOSE: To analyze the impact of urinary diversion type following radical cystectomy (RC) on readmission and short-term mortality rates. METHODS: Patients who underwent RC for bladder cancer in the National Cancer Data Base were grouped based on the type of urinary diversion performed: non-continent [ileal conduit (IC)] or two continent techniques [continent pouch (CP) and orthotopic neobladder (NB)]. We used propensity score matching and multivariable logistic regression models to compare 30-day readmission and 30- and 90-day mortality between the different types of urinary diversion. RESULTS: Among 11,933 patients who underwent RC, we identified 10,197 (85.5%) IC, 1044 (8.7%) CP, and 692 (5.8%) NB. Patients who received IC were significantly older and had more comorbidities (p < 0.0001). Continent diversions were more likely to be performed at an academic center (p < 0.0001). Surgery performed at a non-academic center was an independent predictor of 30-day readmission (OR 1.19, p = 0.010) and 30-day mortality (OR 1.27, p = 0.043). Patients undergoing NB had an increased likelihood of being readmitted (OR 1.41, p = 0.010). There was no significant difference in short-term mortality between groups. CONCLUSIONS: Patients undergoing NB had marginally increased rates of readmission compared to IC. Surgery performed at a non-academic center was associated with higher readmission and 30-day mortality. Similar short-term mortality rates were observed among the different types of urinary diversion.
