RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

OBJECTIVE: To compare survival outcome between chemoradiation therapy (CRT) and radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC). PATIENTS AND METHODS: We conducted a retrospective analysis of patients with MIBC (≥cT2, N0, M0) in the National Cancer Database (2004-2013). CRT was defined as a radiation dose of ≥40 Gy and chemotherapy within 90 days of radiation. Descriptive statistics were used to compare groups. RC and CRT patients were propensity matched. Kaplan-Meier analysis was used to compare overall survival (OS). Multivariable Cox regression was used to determine predictors of survival. RESULTS: In all, 8 379 (6 606 RC and 1 773 CRT) patients met the inclusion criteria and 1 683 patients in each group were propensity matched. On multivariable extended Cox analysis, significant predictors of decreased OS were age, Charlson-Deyo Comorbidity score of 1, Charlson-Deyo Comorbidity score of 2, stage cT3-4, and urothelial histology. CRT was associated with decreased mortality at year 1 (hazard ratio [HR] 0.84, 95% confidence interval [CI] 0.74-0.96; P = 0.01), but at 2 years (HR 1.4, 95% CI 1.2-1.6; P < 0.001) and 3 years onward (HR 1.5, 95% CI 1.2-1.8; P < 0.001) CRT was associated with increased mortality. The 5-year OS was greater for RC than for CRT (38% vs 30%, P = 0.004). CONCLUSIONS: Initially after treatment for MIBC the risk of mortality is lower with CRT compared to RC. However, at ≥2 years after treatment the mortality risk favours RC. Patients who are suitable surgical candidates, with a low risk of morbidity, may be better served by RC.

RESUMEN

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.

RESUMEN

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.

RESUMEN

INTRODUCTION: The aim of the study was to determine whether perioperative complications and postoperative outcomes varied with the indication of partial nephrectomy (PN). MATERIALS AND METHODS: We reviewed data of 184 consecutive PN for suspected renal cell carcinoma operated between January 2004 and December 2013. Complications using the Clavien-Dindo classification were compared between surgeries for absolute indications (chronic renal failure, bilateral tumors, or solitary kidney), those for relative indications (comorbid illnesses with the potential to affect renal function) and elective indications (patients without risk factors). Complex tumors were defined as size >7 cm, multiple, hilar, and endophytic tumors. RESULTS: Patients with an absolute indication had larger tumors (P = 0.001) and tumors of a higher pathological T-stage (P = 0.03). Minor complications (Clavien 1 and 2) occurred in 25.4% patients in the elective arm versus over 40% in the other arms (P = 0.049). Major complications (Clavien 3+) were less common in the elective arm (3.2% cases vs. 12.7% in the relative arm and 13.8% in the absolute arm) with a trend to significance (P = 0.09). On multivariate analysis, absolute indication (odds ratio [OR] = 2.4, P = 0.04) and surgery for a complex renal mass (OR = 2.5 times, P = 0.03) remained significant predictors of minor complications. Major complications were more common in the relative (OR = 5.5, P = 0.057) and absolute indication arm (OR = 5.231, P = 0.051) with a trend toward significance. CONCLUSIONS: Elective indication was associated with fewer complications than PN for relative or absolute indications.

RESUMEN

A 12-year-old boy presented with poor flow and recurrent urinary tract infections following hypospadias repair at the age of 3 years. The evaluation revealed urethral duplication with a hypoplastic dorsal urethra and patent ventral urethra. He also had duplication of the bladder neck, and on voiding cystourethrogram the ventral bladder neck appeared hypoplastic and compressed by the dorsal bladder neck during voiding. The possibility of functional obstruction of the ventral urethra by the occluded dorsal urethra was suspected, and he underwent a successful urethro-urethrostomy.

RESUMEN

Urology, as a specialty, has always been at the forefront of innovation and research. Newer technologies have been rapidly embraced and, in many cases, improved upon in order to achieve better patient outcomes. This review addresses the possible future directions that technological advances in urology may take. The role of further miniaturization of urolithiasis treatment, robotic surgery and other minimally invasive techniques is addressed. The potential for enhanced imaging and diagnostic techniques like magnetic resonance imaging and ultrasonography modifications, as well as the potential applications of nanotechnology and tissue engineering, are reviewed. This article is based on the Dr. Sitharaman Best Essay award of the Urological Society of India for 2013.

RESUMEN

INTRODUCTION: Our aim was to determine the correlation of platelet count with stage and grade of renal cell carcinoma (RCC) and to determine whether progression of disease was more likely in those with thrombocytosis. MATERIALS AND METHODS: A retrospective review of patients with RCC from January 2004 to December 2011 was undertaken. Patients with no preoperative platelet count and those with multiple tumors were excluded. Disease progression was defined as appearance of local recurrence or distant metastasis on follow-up. Thrombocytosis was defined as a platelet count of >400,000/cumm. Standard tests of significance and multivariate analysis using logistic regression were performed. RESULTS: A total of 322 cases were identified. The median follow-up was 7 months (range, 2-84 months). The platelet count correlated significantly with higher Fuhrmann grade, as well as increasing TNM stage at diagnosis. Patients with a platelet count of >400,000/cumm (n = 35) had a significantly higher mean tumor size and worse grade at diagnosis than those with a normal platelet count (n = 287). Patients with thrombocytosis also had a significantly worse stage at presentation. Progression of disease was seen more often in patients with thrombocytosis (28.6% vs 11.9%, P = 0.07). The median time to progression was significantly faster in patients with thrombocytosis (9 vs 18 months, P = 0.018). However, on multivariate analysis TNM stage was the only significant predictor of time to progression. CONCLUSION: Rising platelet count correlated significantly with advancing stage and grade of disease. Patients with thrombocytosis were significantly more likely to have advanced tumors at presentation, poorer histological features, and rapid disease progression.

RESUMEN

PURPOSE: We compared the safety and efficacy of bipolar transurethral resection and monopolar resection for bladder tumors. MATERIALS AND METHODS: A single center, parallel arm, randomized, controlled trial was performed from May 2011 to August 2012. All patients with suspected bladder tumors were eligible for study inclusion. Those who refused consent and those undergoing routine restaging transurethral resection of bladder tumor were excluded from analysis. The primary end point was the incidence of obturator jerk. Secondary study outcomes included the decrease in hematocrit, rates of recoagulation and transfusion, bladder perforation, decrease in sodium, resection syndrome and resection time. Pathological quality was assessed by comparing deep muscle and the degree of severe cautery artifact in the 2 arms. RESULTS: A total of 257 transurethral resections were performed during the study period. After exclusion 147 patients were randomized, including 75 in the monopolar arm and 72 in the bipolar arm. There were 6 and 4 protocol violations in the monopolar and bipolar arms, respectively. Intent to treat and per protocol analyses were performed. The incidence of obturator jerk was greater in the bipolar arm (60% vs 49.2%, p=0.27). There was no significant difference between secondary outcomes. The only significant difference was a significantly lower incidence of severe cautery artifact in the bipolar arm (25% vs 46.7%, p=0.0096). CONCLUSIONS: Bipolar transurethral resection of bladder tumor was not superior to monopolar resection with respect to obturator jerk, bladder perforation and hemostasis. There was a significantly lower incidence of severe cautery artifact after bipolar resection.

RESUMEN

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.
