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

PURPOSE: Fistula formation is a rare and poorly described complication following radical cystectomy with urinary diversion. We sought to identify patients who experienced any type of fistulous complication and we analyzed risk factors for formation as well as management outcomes. MATERIALS AND METHODS: We retrospectively reviewed the records of patients who underwent radical cystectomy for bladder cancer at our institution. Patients who experienced any fistula were identified. Risk factors, management strategies and outcomes were analyzed. Patients underwent initial conservative treatment and those in whom this treatment failed underwent surgical repair. Univariable and multivariable analyses were performed to identify predictors of fistula formation as well as the need for surgical repair. RESULTS: Of the 1,041 patients 31 (3.0%) experienced fistula formation. Median time to fistula presentation was 31 days. Enterodiversion was the most common fistula type, noted in 54.8% of patients, followed by enterocutaneous and diversion cutaneous treatment in 29.0% and 12.9%, respectively. On multivariable analyses a history of radiation therapy (OR 3.1, p = 0.03) and an orthotopic neobladder (OR 3.1, p = 0.04) were predictors of fistula formation. Conservative management was successful in 41.9% of cases. There were no predictors of failed conservative management. Of patients who required surgical repair success was achieved in 94.4% at a single operation. CONCLUSIONS: Fistulas are rare after radical cystectomy and they are most common between the urinary diversion and the small bowel. A history of radiation therapy and a orthotopic neobladder are risk factors for formation. When required, surgical repair is generally successful at a single operation.

RESUMEN

PURPOSE: Venous thromboembolic events are a significant source of morbidity after radical cystectomy. At our institution subcutaneous heparin was historically given to patients undergoing radical cystectomy immediately before incision and throughout the inpatient stay. In an effort to decrease the overall rate of venous thromboembolism and post-discharge venous thromboembolism, a regimen including extended duration enoxaparin was initiated for patients undergoing radical cystectomy. MATERIALS AND METHODS: In January 2013 thromboprophylaxis was modified for patients undergoing radical cystectomy by replacing a regimen of subcutaneous heparin before induction and then every 8 hours until discharge home with enoxaparin daily for postoperative prophylaxis continued until 28 days after discharge. Data from our institutional radical cystectomy database for patients undergoing surgery from January 2011 to May 2014 were reviewed. The primary outcome was clinically symptomatic postoperative venous thromboembolism. Secondary outcomes included timing of venous thromboembolism and blood transfusions. Multivariate logistic regression was used to control for differences between cohorts. RESULTS: Of the 402 patients 234 underwent radical cystectomy before the change and 168 after. The enoxaparin regimen decreased the rate of venous thromboembolism (12% vs 5%, p=0.024) with the main benefit on post-discharge venous thromboembolism (6% vs 2%, p=0.039). Overall 17 of 37 (46%) venous thromboembolisms occurred after discharge home. Multivariate analysis confirmed that the enoxaparin regimen was independently associated with reduced odds of venous thromboembolism (OR 0.33, 95% CI 0.14-0.76, p=0.009). Intraoperative and postoperative transfusion rates were similar between cohorts. CONCLUSIONS: Thromboprophylaxis with extended duration enoxaparin decreased the rate of venous thromboembolism after radical cystectomy compared to inpatient only subcutaneous heparin with no increased risk of bleeding.

RESUMEN

PURPOSE: Alvimopan has decreased ileus and need for nasogastric tube (NGT) after radical cystectomy (RC). However, the natural history of ileus versus intestinal obstruction in patients receiving alvimopan is not well defined. We sought to examine the implications of NGT placement before and after the introduction of alvimopan for RC patients. METHODS: Retrospective review identified 278 and 293 consecutive patients who underwent RC before and after instituting alvimopan between June 2009 and May 2014. Baseline characteristics and postoperative outcomes were compared by alvimopan status. Multivariate logistic regression was performed to assess the impact of alvimopan on rates of NGT placement and reoperation for bowel complications. RESULTS: The cohorts had similar age, stage, approach, and BMI. Patients receiving alvimopan had decreased ileus (16 vs 32 %, p < 0.01) but similar rates of reoperation for bowel complications (2.8 vs 2.7 %). On multivariate analysis, alvimopan was associated with lower risk of NGT placement (OR 0.30, p < 0.01). For patients requiring NGT placement, there was an increased rate of reoperation among patients receiving alvimopan compared with those who did not (28 vs 11 %, p = 0.03). Patients receiving alvimopan who needed NGT had significantly increased median length of stay (22 vs 7 days), need for TPN (66 vs 5.3 %), and readmission for ileus (10.3 vs 2.3 %) compared with those who did not require NGT. CONCLUSIONS: Alvimopan significantly reduced the incidence of ileus and NGT placement following RC. NGT placement was associated with an increased need for reoperation for bowel complications in the setting of alvimopan.

RESUMEN

PURPOSE: We assessed the association of temporal, socioeconomic and environmental factors with bladder cancer mortality in the United States. Our hypothesis was that bladder cancer mortality is associated with distinct environmental and socioeconomic factors with effects varying by region, race and gender. MATERIALS AND METHODS: NCI (National Cancer Institute) age adjusted, county level bladder cancer mortality data from 1950 to 2007 were analyzed to identify clusters of increased bladder cancer death using the Getis-Ord Gi* statistic. Socioeconomic, clinical and environmental data were assessed using geographically weighted spatial regression analysis adjusting for spatial autocorrelation. County level socioeconomic, clinical and environmental data were obtained from national databases, including the United States Census, CDC (Centers for Disease Control and Prevention), NCHS (National Center for Health Statistics) and County Health Rankings. RESULTS: Bladder cancer mortality hot spots and risk factors for bladder cancer death differed significantly by gender, race and geographic region. From 1996 to 2007 smoking, unemployment, physically unhealthy days, air pollution ozone days, percent of houses with well water, employment in the mining industry and urban residences were associated with increased rates of bladder cancer mortality (p <0.05). Model fit was significantly improved in hot spots compared to all American counties (R(2) = 0.20 vs 0.05). CONCLUSIONS: Environmental and socioeconomic factors affect bladder cancer mortality and effects appear to vary by gender and race. Additionally there were temporal trends of bladder cancer hot spots which, when persistent, should be the focus of individual level studies of occupational and environmental factors.

RESUMEN

PURPOSE: Although associated with an overall favorable survival rate, the heterogeneity of non-muscle invasive bladder cancer (NMIBC) affects patients' rates of recurrence and progression. Risk stratification should influence evaluation, treatment and surveillance. This guideline attempts to provide a clinical framework for the management of NMIBC. MATERIALS AND METHODS: A systematic review utilized research from the Agency for Healthcare Research and Quality (AHRQ) and additional supplementation by the authors and consultant methodologists. Evidence-based statements were based on body of evidence strength Grade A, B, or C and were designated as Strong, Moderate, and Conditional Recommendations with additional statements presented in the form of Clinical Principles or Expert Opinions.(1) RESULTS: A risk-stratified approach categorizes patients into broad groups of low-, intermediate-, and high-risk. Importantly, the evaluation and treatment algorithm takes into account tumor characteristics and uniquely considers a patient's response to therapy. The 38 statements vary in level of evidence, but none include Grade A evidence, and many were Grade C. CONCLUSION: The intensity and scope of care for NMIBC should focus on patient, disease, and treatment response characteristics. This guideline attempts to improve a clinician's ability to evaluate and treat each patient, but higher quality evidence in future trials will be essential to improve level of care for these patients.

RESUMEN

The purpose of the RAZOR (randomized open vs robotic cystectomy) study is to compare open radical cystectomy (ORC) vs robot-assisted RC (RARC), pelvic lymph node dissection (PLND) and urinary diversion for oncological outcomes, complications and health-related quality of life (HRQL) measures with a primary endpoint of 2-year progression-free survival (PFS). RAZOR is a multi-institutional, randomized, non-inferior, phase III trial that will enrol at least 320 patients with T1-T4, N0-N1, M0 bladder cancer with ≈160 patients in both the RARC and ORC arms at 15 participating institutions. Data will be collected prospectively at each institution for cancer outcomes, complications of surgery and HRQL measures, and then submitted to trial data management services Cancer Research and Biostatistics (CRAB) for final analyses. To date, 306 patients have been randomized and accrual to the RAZOR trial is expected to conclude in 2014. In this study, we report the RAZOR trial experimental design, objectives, data safety, and monitoring, and accrual update. The RAZOR trial is a landmark study in urological oncology, randomizing T1-T4, N0-N1, M0 patients with bladder cancer to ORC vs RARC, PLND and urinary diversion. RAZOR is a multi-institutional, non-inferiority trial evaluating cancer outcomes, surgical complications and HRQL measures of ORC vs RARC with a primary endpoint of 2-year PFS. Full data from the RAZOR trial are not expected until 2016-2017.

RESUMEN

The role of tissue engineering in the cystectomy population rests on the principle of sparing healthy intestinal tissue while replacing diseased bladder. Over the last 25 years advances in cell biology and material science have improved the quality and durability of bladder replacement in animals. The neo-urinary conduit ([NUC]-Tengion) employs autologous fat smooth muscle cells which are seeded onto synthetic, biodegradable scaffolds. This seeded construct is then implanted in the patient and purportedly regenerates native urinary tissue to serve as a passive channel connecting the ureters to the skin surface. Preclinical animal studies as well as the first phase I human trial implanting the NUC are reviewed. While the ultimate goal of creating a durable, effective, tissue-engineered conduit is still in its infancy, important technical and experimental strides have been made.

RESUMEN

PURPOSE: Transurethral bladder tumor resection is one of the most commonly performed procedures by practicing urologists for the diagnosis, staging and treatment of nonmuscle invasive bladder cancer. There is wide variation in the technique and quality of transurethral bladder tumor resection among urologists. This is the first and critically important diagnostic and staging tool in the management of bladder cancer, which is a potentially lethal malignancy and the most costly urological malignancy to manage. In this review we provide an evidence-based rationale for the incorporation of novel technologies for transurethral resection of bladder tumor in the setting of previously set standards. MATERIALS AND METHODS: A systematic MEDLINE®/PubMed®, Cochrane Library and Ovid MEDLINE® search was performed using 2 separate search queries. The MEDLINE/PubMed search was performed using the key words "transurethral resection bladder tumor," filtering the search to include studies published within the last 5 years, English language and human species. A second search without filters was performed with the same key words in the Cochrane Library and Ovid MEDLINE. Study eligibility was defined based on patients with nonmuscle invasive bladder cancer, treatment with transurethral bladder tumor resection and with variable comparators based on novel technology used. All study designs were accepted except case reports, animal studies, editorials and review articles with various outcome measures reported including tumor detection, residual tumor detection, disease recurrence/progression and adverse events. RESULTS: The literature search ultimately yielded 971 manuscripts for review with 42 meeting inclusion criteria for systematic review. Refinements in technique and surgeon experience are critical for the performance of a thorough, complete, high quality transurethral bladder tumor resection. Recent technological advances including bipolar electrocautery and regional anesthetic techniques may help reduce the complications associated with transurethral bladder tumor resection. Photodynamic diagnosis may help increase the diagnostic accuracy, reduce the recurrence rate and decrease the cost of treating patients with nonmuscle invasive bladder cancer. Repeat transurethral bladder tumor resection and perioperative intravesical chemotherapy remain standard components in select patients with nonmuscle invasive bladder cancer. Appropriate clinical staging and treatment of patients with nonmuscle invasive bladder cancer remain a challenge. CONCLUSIONS: Recent advances in transurethral bladder tumor resection should aid its diagnostic accuracy, reduce recurrences, decrease complications and reduce the cost of management of nonmuscle invasive bladder cancer. Urologists should incorporate these evidence-based strategies into current guideline recommendations to improve patient outcomes following transurethral resection of bladder tumor in everyday practice.

RESUMEN

PURPOSE: Benign ureterointestinal anastomotic stricture is not uncommon after radical cystectomy and urinary diversion. We studied the impact of the running vs the interrupted technique on the ureterointestinal anastomotic stricture rate. MATERIALS AND METHODS: From July 2007 to December 2008 interrupted end-to-side anastomoses were created and from January 2009 to July 2010 running anastomoses were created. The primary study end point was time to ureterointestinal anastomotic stricture. RESULTS: Of 266 consecutive patients 258 were alive 30 days after radical cystectomy, including 149 and 109 with an interrupted and a running anastomosis, respectively. The groups did not differ in age, gender, body mass index, age adjusted Charlson comorbidity index, receipt of chemotherapy or radiation, blood loss, operative time, diversion type or postoperative pathological findings. The stricture rate per ureter was 8.5% (25 of 293) and 12.7% (27 of 213) in the interrupted and running groups, respectively (p = 0.14). Univariate analysis suggested that postoperative urinary tract infection (HR 2.1, 95% CI 1.1-4.1, p = 0.04) and Clavien grade 3 or greater complications (HR 2.6, 95% CI 1.4-4.9, p <0.01) were associated with ureterointestinal anastomotic stricture. On multivariate analysis postoperative urinary tract infection (HR 2.4, 95% CI 1.2-5.1, p = 0.02) and running technique (HR 1.9, 95% CI 1.0-3.7, p = 0.05) were associated with ureterointestinal anastomotic stricture. Median time to stricture and followup was 289 (IQR 120-352) and 351 days (IQR 132-719) in the running cohort vs 213 (IQR 123-417) and 497 days (IQR 174-1,289) in the interrupted cohort, respectively. Of the 52 strictures 33 (63%) developed within 1 year. Kaplan-Meier analysis controlling for differential followup showed a trend toward higher freedom from stricture for the interrupted ureterointestinal anastomosis (p = 0.06). CONCLUSIONS: A running anastomosis and postoperative urinary tract infection may be associated with ureterointestinal anastomotic stricture. Larger series with multiple surgeons are needed to confirm these findings.

RESUMEN

OBJECTIVE: To determine the impact of empiric antibiotics on men with an elevated prostate-specific antigen (PSA) level. SUBJECTS/PATIENTS AND METHODS: Men of any age with a PSA level of >2.5 ng/mL and normal digital rectal examination undergoing their first prostate biopsy were recruited from five medical centres. Patients with previous biopsy, prostate cancer, urinary tract infection (UTI) or prostatitis within the prior year, antibiotic use within 1 month, 5α-reductase inhibitor use, allergy to fluoroquinolones or clinical suspicion of UTI were excluded. Men were randomised to 2 weeks of ciprofloxacin or no antibiotic. A PSA measurement was obtained 21-45 days after randomisation immediately before prostate biopsy. The primary endpoint was the change in PSA level between baseline and immediately before biopsy. RESULTS: Complete data were available for 77 men with a mean (interquartile range) age of 60.6 (53-66) years. In the control group of men not receiving antibiotic (39 men), the mean baseline and pre-biopsy PSA levels were 6.5 and 6.9 ng/mL, respectively (P = 0.8). In men receiving ciprofloxacin (38 men), the mean baseline PSA level was 7.6 ng/mL and after 2 weeks of ciprofloxacin was 8.5 ng/mL (P = 0.7). Compared with controls not receiving antibiotic, use of ciprofloxacin was not associated with a statistically significant change in PSA level (P = 0.33). Prostate cancer was detected in 36 (47%) men, 23 (59%) in the control group and 13 (34%) in the antibiotic group (P = 0.04). Detection rates were not significantly associated with the change in PSA level between baseline and biopsy. The primary limitation of the study is early stoppage due to an interim futility analysis and poor accrual. CONCLUSION: Despite not meeting the target accrual goal, empiric use of antibiotics for asymptomatic men with an elevated PSA level does not appear to be of clinical benefit.

RESUMEN

We report the development of a previously undescribed gold nanoparticle bio-barcode assay probe for the detection of prostate specific antigen (PSA) at 330 fg/mL, automation of the assay, and the results of a clinical pilot study designed to assess the ability of the assay to detect PSA in the serum of 18 men who have undergone radical prostatectomy for prostate cancer. Due to a lack of sensitivity, available PSA immunoassays are often not capable of detecting PSA in the serum of men after radical prostatectomy. This new bio-barcode PSA assay is approximately 300 times more sensitive than commercial immunoassays. Significantly, with the barcode assay, every patient in this cohort had a measurable serum PSA level after radical prostatectomy. Patients were separated into categories based on PSA levels as a function of time. One group of patients showed low levels of PSA with no significant increase with time and did not recur. Others showed, at some point postprostatectomy, rising PSA levels. The majority recurred. Therefore, this new ultrasensitive assay points to significant possible outcomes: (i) The ability to tell patients, who have undetectable PSA levels with conventional assays, but detectable and nonrising levels with the barcode assay, that their cancer will not recur. (ii) The ability to assign recurrence earlier because of the ability to measure increasing levels of PSA before conventional tools can make such assignments. (iii) The ability to use PSA levels that are not detectable with conventional assays to follow the response of patients to adjuvant or salvage therapies.

RESUMEN

OBJECTIVE: To determine exposure rates to antibiotics prior to radical cystectomy and determine if there is correlation with post-operative infections. METHODS AND MATERIALS: 2248 patients were identified in the 2016 SEER-Medicare linkage who underwent radical cystectomy between 2008 and 2014 with complete prescription information. An outpatient prescription for an antibiotic within 30 days prior to cystectomy was considered exposure. Antibiotic class and combinations were recorded. Postoperative infectious diagnoses and readmissions were tabulated within 30 days of cystectomy. RESULTS: Fifty one percent of patients (n = 1149) were prescribed an outpatient antibiotic prior to cystectomy. Patients receiving antibiotics were more likely to be female (31% vs 25%, P < .01) and had been diagnosed with an infection (17% vs 11%, P < .01). Antibiotic bowel prophylaxis was prescribed to 42% of patients receiving antibiotics. Postoperatively, the exposure group had higher rates of any infection, (56% vs 51% P < .01) and UTI (36% vs 31% P < .01). All-cause readmission within 30 days was higher in the exposure cohort (26% vs 22%, P = .02) Multivariable logistic regression showed outpatient preoperative antibiotics were an independent risk factor for any infection (HR 1.19, P < .05) and readmission (hazards ratio 1.24, P = .03) in the 30 days after radical cystectomy. CONCLUSION: Outpatient antibiotic use prior to radical cystectomy is common and may be associated with increased risk of postoperative infection and readmission. Antibiotic use prior to radical cystectomy should be examined as a modifiable factor to decrease post-operative morbidity.

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.

RESUMEN

BACKGROUND: Inferior vena cava (IVC) reconstruction for locally advanced renal cell carcinoma (RCC) includes resection with and without interposition grafting, patch graft, or primary repair. The proposed benefits of lateral venorrhaphy and primary repair are avoidance of foreign material, a more expeditious repair, and preservation of lower extremity venous outflow. METHODS: A single-center retrospective review of 22 patients with RCC and IVC tumor thrombus treated with radical nephrectomy, lateral venorrhaphy, thrombectomy, and primary vena cava repair between July 2002 and June 2009 was carried out. Demographic data, diagnostic information, radiographic cross-sectional imaging, and procedural outcomes were examined. RESULTS: Among the 13 men and nine women, the mean age was 62.1 years (42-83); mean tumor size was 9.8 cm (3-17 cm), and 90% (n = 18) of the cases with RCC were identified pathologically as clear cell adenocarcinoma; on the basis of the classification system adopted by Neves, level I was for 50% (n = 11), level II for 32% (n = 7), level III for 9% (n = 2), and level IV for 9% (n = 2) of the patients. All patients underwent en bloc radical nephrectomy with tumor thrombus removal and primary IVC repair. Mean total operative time was 547.9 ± 138.5 minutes, whereas mean IVC cross-clamp time was 10.8 minutes (6-29 minutes). There were no intraoperative deaths or pulmonary embolism and all IVC margins were found to be pathologically negative. Postoperative complications included one pulmonary embolism, one exacerbation of chronic lymphedema, and two cases of new onset erectile dysfunction. Mean follow-up was 36.4 ± 23.2 months (6-92 months). There were no radiographic or clinically significant changes in mean IVC diameter during follow-up. Five late deaths (23%) occurred as a result of metastatic RCC over a mean period of 24 months (range, 12-48), but without any local recurrences. CONCLUSION: For advanced RCC with tumor thrombus extension into the IVC, lateral venorrhaphy and primary IVC repair avoids complicated caval reconstructions and results in high patency rates with a low local tumor recurrence rate.

RESUMEN

INTRODUCTION: While numerous current clinical trials are testing novel salvage therapies (ST) for patients with recurrent nonmuscle invasive bladder cancer (NMIBC) after bacillus Calmette-Guérin (BCG), the natural history of this disease state has been poorly defined to date. Herein, we evaluated oncologic outcomes in patients previously treated with BCG and ST who subsequently underwent radical cystectomy (RC). METHODS: We identified 378 patients with high-grade NMIBC who received at least one complete induction course of BCG (n = 378) with (n = 62) or without (n = 316) additional ST and who then underwent RC between 2000 and 2018. Oncologic outcomes were compared using the Kaplan-Meier method and Cox proportional hazards models. Sensitivity analyses were conducted stratifying by presenting tumor stage, matched 1:3 for receipt vs. no receipt of ST. RESULTS: Patients receiving ST were more likely to initially present with CIS (26% vs. 17%) and less likely with T1 disease (34% vs. 50%, P = 0.06) compared to patients not treated with ST. Receipt of ST was not associated with increased risk of adverse pathology (≥pT2 or pN+) at RC (31% vs. 41%, P = 0.14). Likewise, 5-year cancer-specific survival did not significantly differ between groups on univariable Kaplan-Meier analysis (73% for ST and 74% for no ST, P = 0.7). Moreover, on multivariable analysis, receipt of ST was not significantly associated the risk of death from bladder cancer (HR 1.12; 95% CI 0.60-2.09, P = 0.7). Results were unchanged on sensitivity analysis. CONCLUSIONS: These data suggest that, in carefully selected patients, ST following BCG for high grade NMIBC does not compromise oncologic outcomes for patients who ultimately undergo RC.

RESUMEN

PURPOSE: The Prostate Cancer Prevention Trial reported that 15% of men with a prostate specific antigen less than 4 ng/ml and a normal digital rectal examination have biopsy detectable prostate cancer. However, limited published data describe the tumor features of prostate cancer detected at low prostate specific antigen levels (less than 2.5 ng/ml). MATERIALS AND METHODS: A total of 1,278 men underwent radical retropubic prostatectomy by 1 surgeon between 2003 and 2008. We describe the clinicopathological features of 77 patients with a preoperative prostate specific antigen of less than 2.5 ng/ml. RESULTS: Of the men with a low prostate specific antigen (less than 2.5 ng/ml) tumor 51 (66%) had findings suspicious for prostate cancer on digital rectal examination. Indications for prostate biopsy in the remainder of men included an increased prostate specific antigen velocity, hematospermia and abnormal transrectal ultrasound findings. Prostate cancer was detected at transurethral resection of the prostate in the remaining 8% of men. Despite having a low prostate specific antigen at diagnosis 8 (10.4%) and 20 (26%) men, respectively, had biopsy and radical retropubic prostatectomy Gleason grade 7 disease or greater, while 7 (9%) and 6 (7.8%), respectively, had extracapsular tumor extension or positive surgical margins. Compared to men with a normal digital rectal examination mean tumor volume was significantly higher in those with a suspicious digital rectal examination (3.3 vs 1.7 cc, p = 0.018). CONCLUSIONS: Despite having a prostate specific antigen of less than 2.5 ng/ml at diagnosis, a considerable proportion of men had aggressive pathological features at radical retropubic prostatectomy. Digital rectal examination remains an important component of early prostate cancer detection.

RESUMEN

OBJECTIVE: To compare the outcomes between patients with stage T1a/b with those of patients with T1c cancer of the prostate treated with radical retropubic prostatectomy (RRP), as the appropriate management of clinical stage T1a/b prostate cancer is subject to debate; although many patients are managed expectantly, some have adverse pathological features suggesting that more active treatment might be beneficial. PATIENTS AND METHODS: From 1983 to 2003, 3478 men had RRP by one surgeon. From this group, we retrospectively identified 29 men with clinical stage T1a and 83 with clinical stage T1b disease. Using statistical analysis we compared the treatment outcomes of these patients with those of 1774 men with clinical stage T1c disease. RESULTS: Men with T1a/b disease had a significantly lower preoperative prostate-specific antigen (PSA) level, a greater proportion with organ-confined disease, and a lower mean/median prostatectomy Gleason score than those with T1c disease. Also, men with T1a/b disease were less likely to be potent before surgery, although the frequency of recovery of potency was similar among all groups. On multivariate analysis with age, year of surgery, PSA level and Gleason score, there was no statistical difference in the rates of biochemical recurrence and the 10-year overall survival rates. However, patients with T1b disease had a significantly lower cancer-specific survival. CONCLUSIONS: T1a and T1b prostate cancer can be associated with aggressive pathological features and have a similar rate of progression as clinical stage T1c disease. That notwithstanding, most patients in the study were cured with RRP and had favourable long-term functional outcomes.
