RESUMO

PURPOSE: To evaluate the value of examination under anesthesia (EUA) in the assessment of bladder resectability during cystectomy. MATERIALS AND METHODS: This prospective study included consecutive patients undergoing cystectomy for bladder cancer at a single center between June 2017 and October 2020. EUA was conducted before cystectomy by two urologists who assessed the bladder for limited mobility. One examiner was blinded to the imaging results. Soft tissue surgical margin status in the pathological evaluation of a cystectomy specimen served as a measure of resectability. We used multivariable logistic regression models to assess whether EUA performed by blinded or non-blinded examiners is associated with soft tissue positive surgical margins (PSMs) and to calculate the fraction of new information added by such an examination in addition to selected clinical variables. RESULTS: Among the 134 patients analyzed, limited bladder mobility was indicated by the blinded and non-blinded examiners in 23 (17.2%) and 21 (15.7%) cases, respectively. PSMs were identified in 22 (16.4%) patients, more often in patients with limited bladder mobility as assessed by the blinded (odds ratio [OR] 6.7; 95% confidence interval [CI], 1.9-24.2) and non-blinded examiners (OR 12.9; 95% CI, 2.9-57.5). The fraction of new information added by the blinded and non-blinded examiners was 48.6% and 57.7%, respectively. The enrichment of patients who underwent pure laparoscopic cystectomy (n = 102; 76%) and the inclusion of patients for emergent surgery may limit the generalizability of our findings. CONCLUSIONS: The identification of limited bladder mobility during preoperative EUA yielded prognostic information on surgical margin status. Our findings suggest that EUA has the potential to provide valuable insights in the assessment of bladder resectability. However, further research in a larger cohort of patients is warranted to validate and expand on these findings.

RESUMO

BACKGROUND: Financial toxicity of bladder cancer care may influence how patients utilize healthcare resources, from emergency department (ED) encounters to office visits. We aim to examine whether greater household net worth (HHNW) confers differential access to healthcare resources after radical cystectomy (RC). METHODS: This population-based cohort study examined the association between HHNW and healthcare utilization costs in the 90 days post-RC in commercially insured patients with bladder cancer. Costs accrued from the index hospitalization to 90 days after including health plan costs (HPC) and out-of-pocket costs (OPC). Multivariable logistic regression models were generated by encounter (acute inpatient, ED, outpatient, and office visit). RESULTS: A total of 141,903 patients were identified with HHNW categories near evenly distributed. Acute inpatient encounters incurred the greatest HPC and OPC. Office visits conferred the lowest HPC while ED visits had the lowest OPC. Black patients harbored increased odds of an acute inpatient encounter (OR 1.22, 95% CI 1.16-1.29) and ED encounter (OR 1.20, 95% CI 1.14-1.27) while Asian (OR 0.76, 95% CI 0.69-0.85) and Hispanic (OR 0.74, 95% CI 0.69-0.78, p < 0.001) patients had lower odds of an outpatient encounter, compared to White counterpart. Increasing HHNW was associated with decreasing odds of acute inpatient or ED encounters and greater odds of office visits. CONCLUSIONS: Lower HHNW conferred greater risk of costly inpatient encounters while greater HHNW had greater odds of less costly office visits, illustrating how financial flexibility fosters differences in healthcare utilization and lower costs. HHNW may serve as a proxy for financial flexibility and risk of financial hardship than income alone.

RESUMO

AIM: To investigate whether the Vesical Imaging-Reporting and Data System (VI-RADS) could be used to develop a new non-invasive preoperative grade-prediction system to partially predict high-grade bladder cancer (HG-BC). MATERIALS AND METHODS: The present study enrolled 89 primary BC patients prospectively from March 2022 to June 2023. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the diagnostic performance of VI-RADS for predicting HG-BC and muscle-invasive bladder cancer (MIBC) in the entire group. In the low VI-RADS (≤2) group, the decision tree-based method was used to obtain significant predictors and construct the decision-tree model (DT model). The performance of the DT model and low VI-RADS scores for predicting HG-BC was determined using ROC, calibration, and decision curve analyses. RESULTS: At a cut-off of ≥3, the specificity and positive predictive value of VI-RADS for predicting HG-BC in the entire group was 100%, and the area under the ROC curve (AUC) was 0.697. Among 65 patients with low VI-RADS scores, the DT model showed an AUC of 0.884 in predicting HG-BC compared to 0.506 for low VI-RADS scores. Calibration and decision curve analyses showed that the DT model performed better than the low VI-RADS scores. CONCLUSION: Most VI-RADS scores ≥3 correspond to HG-BCs. VI-RADS could be used as a grouping imaging biomarker for a pathological grade-prediction procedure, which in combination with the DT model for low VI-RADS (≤2) populations, would provide a potential preoperative non-invasive method of predicting HG-BC.

RESUMO

OBJECTIVES: To determine a data-based optimal annual radical cystectomy (RC) hospital volume threshold and evaluate its clinical significance regarding perioperative mortality, complications, length of hospital stay, and hospital revenues. MATERIAL AND METHODS: We used the German Nationwide inpatient Data, provided by the Research Data Center of the Federal Bureau of Statistics (2005-2020). 95,841 patients undergoing RC were included. Based on ROC analyses, the optimal RC threshold to reduce mortality, ileus, sepsis, transfusion, hospital stay, and costs is 54, 50, 44, 44, 71 and 76 cases/year, respectively. Therefore, we defined an optimal annual hospital threshold of 50 RCs/year, and we also used the threshold of 20 RCs/year proposed by the EAU guidelines to perform multiple patient-level analyses. RESULTS: 28,291 (29.5%) patients were operated in low- (< 20 RC/year), 49,616 (51.8%) in intermediate- (20-49 RC/year), and 17,934 (18.7%) in high-volume (≥ 50 RC/year) centers. After adjusting for major risk factors, high-volume centers were associated with lower inpatient mortality (OR 0.72, 95% CI 0.64-0.8, p < 0.001), shorter length of hospital stay (2.7 days, 95% CI 2.4-2.9, p < 0.001) and lower costs (457 Euros, 95% CI 207-707, p < 0.001) compared to low-volume centers. Patients operated in low-volume centers developed more perioperative complications such as transfusion, sepsis, and ileus. CONCLUSIONS: Centralization of RC not only improves inpatient morbidity and mortality but also reduces hospital stay and costs. We propose a threshold of 50 RCs/year for optimal outcomes.

RESUMO

BACKGROUND: Among patients with non-muscle-invasive bladder cancer (NMIBC), systematic reviews showed lower recurrence rate in patients treated with photodynamic diagnosis (PDD)-assisted transurethral resection of bladder tumor (TURBT) than with white-light (WL) TURBT. However, the result is not consistent between clinical trials and the significance of preoperatively available factors in disease recurrence after PDD-TURBT remains unclear. METHODS: The present study retrospectively analyzed 1174 NMIBC patients who underwent TURBT and were followed up for ≥ 6 months. Among 1174 patients, 385 and 789 underwent PDD-TURBT with oral 5-aminolevulinic acid (the PDD group) and WL-TURBT (the WL group), respectively. Recurrence-free survival (RFS) was compared between the PDD and WL groups before and after propensity score matching, and the impact of several baseline parameters on RFS between the 2 groups was investigated after matching. RESULTS: Before propensity score matching, RFS was significantly longer in the PDD group than in the WL group (P = 0.006). After matching, 383 patients were included in both groups, and RFS was significantly longer in the PDD group than in the WL group (P < 0.001). In the cohort after matching, RFS between the two groups was compared in each subgroup classified according to baseline parameters, including age, sex, history of previous or concomitant upper urinary tract urothelial carcinoma, preoperative urinary cytology, tumor multiplicity, and tumor size, and significantly longer RFS was observed in the PDD group in all subgroups, except for the patients with tumors ≥ 30 mm (P = 0.21). CONCLUSION: These results suggest that PDD-TURBT prolongs RFS in NMIBC patients, except for those with tumors ≥ 30 mm.

RESUMO

OBJECTIVES: To assess whether office-based fulguration (OF) under local anaesthesia for small, recurrent, pathological Ta low-grade (LG) non-muscle-invasive bladder cancer (NMIBC) is an effective alternative to transurethral resection of bladder tumour (TURBT), avoiding the costs and risks of procedure, and anesthesia. PATIENTS AND METHODS: Of 521 patients with primary TaLG NMIBC, this retrospective study included 270 patients who underwent OF during follow-up for recurrent, small, papillary LG-appearing tumours at a university centre (University Health Network, University of Toronto, Canada). We assessed the cumulative incidence of cancer-specific mortality (CSM) and disease progression (to MIBC or metastases), as well as possible direct cost savings. RESULTS: In the 270 patients with recurrent TaLG NMIBC treated with OF, the mean (sd) age was 64.9 (13.3) years, 70.8% were men, and 60.3% had single tumours. The mean (sd, range) number of OF procedures per patient was 3.1 (3.2, 1-22). The median (interquartile range) follow-up was 10.1 (5.8-16.2) years. Patients also underwent a mean (sd) of 3.6 (3.0) TURBTs during follow-up in case of numerous or bulkier recurrence. In all, 44.4% of patients never received intravesical therapy. The 10-year incidence of CSM and progression were 0% and 3.1% (95% confidence interval 0.8-5.4%), respectively. Direct cost savings in Ontario were estimated at $6994.14 (Canadian dollars) per patient over the study follow-up. CONCLUSIONS: This study supports that properly selected patients with recurrent, apparent TaLG NMIBC can be safely managed with OF under local anaesthesia with occasional TURBT for larger or numerous recurrent tumours, without compromising long-term oncological outcomes. This approach could generate substantial cost-saving to healthcare systems, is patient-friendly, and could be adopted more widely.

RESUMO

INTRODUCTION: Intestinal anastomosis can be performed by hand suturing (single layer or double layer) or by a mechanical suturing machine. The aim of the study was to compare complications, operative time, and costs of the intestinal anastomosis techniques. METHODS: A retrospective comparative study was conducted including patients who underwent radical cystectomy and uretero-ileo-cutaneostomy or vescica ileale Padovana orthotopic neobladder. Double-layered hand-sewn intestinal anastomosis (HS-IA) were performed using Vicryl stitches. Mechanical-stapled intestinal anastomosis (MS-IA) were performed with a mechanical stapler. RESULTS: Data of 195 patients who underwent were collected. 100 (51.3%) patients underwent HS-IA and 95 (48.7%) patients underwent MS-IA. Considering the complications classified according to Clavien-Dindo, a statistical difference with higher incidence for grade one in the HS-IA both in the ileal conduit group and in the neobladder one than the MS-IA (15.8% and 8.7%, respectively, in HS-IA vs. 1.7% and none in MS-IA). There is not a significant difference in time to flatus and time to defecation. Difference is recorded in the ileal conduit groups for the length of stay (10 days, range 9-12 with HS-IA vs. 13 days range 12-16 days with MS-IA (p < 0.001). The cost of the suture thread used for a single operation was 0.40 euros, whereas the overall cost of a disposable mechanical stapler and one refill was 350.00 €. CONCLUSION: Both HS-IA and MS-IA are safe and effective for patients. The cost for the stapling device is 350 €, in contrast, the cost for Vicryl sutures is negligible.

RESUMO

BACKGROUND: Radical cystectomy (RC) in bladder cancer patients with cardiovascular comorbidity poses challenges due to the need for antithrombotic therapy and high perioperative risk. We aimed to assess 30-day complications after RC in patients receiving antithrombotic therapy. PATIENTS AND METHODS: Retrospective study of 416 bladder cancer patients (2009-2017) undergoing open RC with pelvic lymph node dissection, with or without antithrombotic therapy. Antithrombotic therapy and complication reporting followed European guidelines. Procedure-specific 30-day complications were cataloged, graded (Clavien-Dindo), and quantified using the 30-day Comprehensive Complication Index. Multivariable regressions evaluated antithrombotic therapy's independent effect on key morbidity outcomes. RESULTS: Median age was 70 years, 78% were male. Patients on antithrombotic therapy were mostly male, had higher comorbidity burden, worse kidney function, more frequent incontinent diversion, and shorter operative time (all p ≤ 0.027). Bleeding complications occurred in 135 patients (32%; 95%CI = 28-37%), more prevalent with antithrombotic therapy (46% vs. 29%; p = 0.004). Thromboembolic complications occurred in 18 patients (4.3%; 95%CI = 2.6-6.8%), no difference between patients with and without antithrombotic therapy (8.4% vs. 3.3%; p = 0.063). Prevalence of myocardial infarction, new-onset hypertension, acute congestive heart failure, and angina pectoris showed no difference (all p ≥ 0.3). Multivariable analyses indicated no association between antithrombotic therapy and cardiac complications, 30-day major complications, or cumulative morbidity (all p ≥ 0.2). Antithrombotic therapy was associated with bleeding complications (OR = 1.92; 95%CI = 1.07-3.45; p = 0.028), predominantly transfusion-related (75% of 152 bleeding complications). Limitations include retrospective data assessment with biases. CONCLUSIONS: RC in patients on antithrombotic therapy exhibits a higher incidence of adverse events due to underlying comorbidities. Adherence to thromboprophylaxis guidelines enables safe RC in patients with significant comorbidities, without substantial increase in major bleeding or severe thromboembolic events.

RESUMO

BACKGROUND: Photodynamic diagnosis-assisted transurethral resection of bladder tumor (PDD-TURBT) showed improvement of diagnostic accuracy and treatment efficacy compared to white light TURBT (WL-TURBT). While PDD-TURBT is highly effective, PDD-TURBT requires the use of PDD device and light-sensitive substance precursor, which increases the medical cost compared to WL-TURBT. In this study, the impact on health care economic costs were examined between PDD-TURBT and WL-TURBT. METHODS: Of the total 265 patients, 88 patients for WL-TURBT and 105 patients for PDD-TURBT were available for analysis. Costs were also examined between 34 patients without false-positives and 36 patients with false-positives with a follow-up period of at least 200 days. To compare costs between the two treatments, we calculated the cost/person/year of TURBT using Japanese Diagnosis Procedure Combination and Per-Diem Payment System (DPC/PDPS). RESULTS: The total number of surgeries including the first TURBT was 135 (47 recurrences) in the WL-TURBT group and 133 (28 recurrences) in the PDD-TURBT group. The cost per person for hospitalization and surgery was 366,310 Japanese yen (JPY) for the WL-TURBT and 501,930 JPY for the PDD-TURBT. The cost per person per year was 491,622 JPY in the WL-TURBT group and 506,405 JPY in the PDD-TURBT group. Regarding false-positives, the cost per person per year was 494,544 JPY in the group without false-positives and 328,086 JPY in the group with false-positives. CONCLUSIONS: Although PDD-TURBT is cost more than WL-TURBT for one surgical hospitalization, the cost per person per year for PDD-TURBT and WL-TURBT is cost-neutral.

RESUMO

Importance: The value to payers of robot-assisted radical cystectomy with intracorporeal urinary diversion (iRARC) when compared with open radical cystectomy (ORC) for patients with bladder cancer is unclear. Objectives: To compare the cost-effectiveness of iRARC with that of ORC. Design, Setting, and Participants: This economic evaluation used individual patient data from a randomized clinical trial at 9 surgical centers in the United Kingdom. Patients with nonmetastatic bladder cancer were recruited from March 20, 2017, to January 29, 2020. The analysis used a health service perspective and a 90-day time horizon, with supplementary analyses exploring patient benefits up to 1 year. Deterministic and probabilistic sensitivity analyses were undertaken. Data were analyzed from January 13, 2022, to March 10, 2023. Interventions: Patients were randomized to receive either iRARC (n = 169) or ORC (n = 169). Main Outcomes and Measures: Costs of surgery were calculated using surgery timings and equipment costs, with other hospital data based on counts of activity. Quality-adjusted life-years were calculated from European Quality of Life 5-Dimension 5-Level instrument responses. Prespecified subgroup analyses were undertaken based on patient characteristics and type of diversion. Results: A total of 305 patients with available outcome data were included in the analysis, with a mean (SD) age of 68.3 (8.1) years, and of whom 241 (79.0%) were men. Robot-assisted radical cystectomy was associated with statistically significant reductions in admissions to intensive therapy (6.35% [95% CI, 0.42%-12.28%]), and readmissions to hospital (14.56% [95% CI, 5.00%-24.11%]), but increases in theater time (31.35 [95% CI, 13.67-49.02] minutes). The additional cost of iRARC per patient was £1124 (95% CI, -£576 to £2824 [US $1622 (95% CI, -$831 to $4075)]) with an associated gain in quality-adjusted life-years of 0.01124 (95% CI, 0.00391-0.01857). The incremental cost-effectiveness ratio was £100 008 (US $144 312) per quality-adjusted life-year gained. Robot-assisted radical cystectomy had a much higher probability of being cost-effective for subgroups defined by age, tumor stage, and performance status. Conclusions and Relevance: In this economic evaluation of surgery for patients with bladder cancer, iRARC reduced short-term morbidity and some associated costs. While the resulting cost-effectiveness ratio was in excess of thresholds used by many publicly funded health systems, patient subgroups were identified for which iRARC had a high probability of being cost-effective.

RESUMO

INTRODUCTION: To examine oncologic outcomes and response to neoadjuvant chemotherapy (NAC) in patients with sarcomatoid urothelial carcinoma (SUC) treated with radical cystectomy (RC). MATERIALS AND METHODS: We retrospectively queried our institutional database (2003-18) and Surveillance, Epidemiology, and End Results (SEER)-Medicare (2004-2015) for patients with cT2-4, N0-2, M0 SUC and conventional UC (CUC) treated with RC. Clinicopathologic characteristics were described using descriptive statistics (t test, χ2-test and log-rank-test for group comparison). Overall (OS) and recurrence-free-survival (RFS) after RC were estimated with the Kaplan Meier method and associations with OS were evaluated with Cox proportional hazards models. RESULTS: We identified 38 patients with SUC and 287 patients with CUC in our database, and 190 patients with SUC in SEER-Medicare. In the institutional cohort, patients with SUC versus CUC had higher rates of pT3/4 stage (66% vs. 35%, P < 0.001), lower rates of ypT0N0 (6% vs. 35%, P = .02), and worse median OS (17.5 vs. 120 months, P < .001). Further, patients with SUC in the institutional versus SEER-Medicare cohort had similar median OS (17.5 vs. 21 months). In both cohorts, OS was comparable between patients with SUC undergoing NAC+RC vs. RC alone (17.5 vs. 18.4 months, P = .98, institutional cohort; 24 vs. 20 months, P = .56, SEER cohort). In Cox proportional hazards models for the institutional RC cohort, SUC was independently associated with worse OS (HR 2.3, CI 1.4-3.8, P = .001). CONCLUSION: SUC demonstrates poor pathologic response to NAC and worse OS compared with CUC, with no OS benefit associated with NAC. A unique pattern of rapid abdominopelvic cystic recurrence was identified.

RESUMO

OBJECTIVES: To build a nomogram prediction model, assess its predictive ability, and perform a survival decision analysis on patients with muscle-invasive bladder cancer (MIBC) to study risk factors affecting overall survival (OS). METHODS: A retrospective analysis was performed on the clinical information of 262 patients with MIBC who underwent radical cystectomy (RC) at the Urology Department of the Second Affiliated Hospital of Kunming Medical University between July 2015 and August 2021. The final model variables that were included were chosen using single-factor stepwise Cox regression, optimal subset regression, and LASSO regression + cross-validation with the minimum AIC value. The next step was to do a multivariate Cox regression analysis. The establishment of a nomogram model by fitting and the screening out of independent risk factors impacting the survival of patients with MIBC having radical resection. Receiver Activity Characteristic curves, C-index, and a calibration plot evaluated the prediction accuracy, validity, and clinical benefit of the model. The 1-, 3-, and 5-year survival rates were then computed for each risk factor using a Kaplan-Meier survival analysis. RESULTS: 262 eligible patients in total were enrolled. With a median follow-up of 32 months, the follow-up period ranged from 2 to 83 months. 171 cases (65.27%) survived while 91 cases (34.73%) perished. Age (HR = 1.06 [1.04; 1.08], p = 0.001), preoperative hydronephrosis (HR = 0.69 [0.46, 1.05], p = 0.087), T stage (HR = 2.06 [1.09, 3.93], p = 0.027), lymphovascular invasion (LVI, HR = 1.73 [1.12, 2.67], p = 0.013), prognostic nutritional index (PNI, HR = 1.70 [1.09, 2.63], p = 0.018), and neutrophil-to-lymphocyte ratio (NLR, HR = 0.52 [0.29, 0.93)], p = 0.026) were independent risk factor for the survival of bladder cancer patients. Create a nomogram based on the aforementioned findings, and then draw the 1-year, 3-year, and 5-year OS receiver operating characteristic curves by the nomogram. The AUC values were 0.811 (95% CI [0.752, 0.869]), 0.814 (95% CI [0.755, 0.873]), and 0.787 (95% CI [0.708, 0.865]), respectively, and the calibration plot matched the predicted value well. The 1-year, 3-year, and 5-year decision curve analyses were higher than the ALL line and None line at threshold values of >5%, 5%-70%, and 20%-70% indicating that the model has good clinical applicability. The calibration plot for the Bootstrap 1000-time resampled validation model was similar to the actual value. Patients with preoperative combination hydronephrosis, higher T-stage, combined LVI, low PNI, and high NLR had worse survival, according to Kaplan-Meier survival analysis for each variable. CONCLUSIONS: This study might conclude that PNI and NLR were separate risk factors that affect a patient's OS after RC for MIBC. The prognosis of bladder cancer may be predicted by PNI and NLR, but additional confirmation in randomized controlled trials is required.

RESUMO

Background and Objectives: To date, sparse evidence exists about the impact of inflammatory serum markers in predicting perioperative complications after radical cystectomy (RC) for bladder cancer (BC). Here, we evaluated the role of the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), systemic immune-inflammation index (SII), C-reactive protein (CRP), and plasma fibrinogen in predicting perioperative morbidity and unplanned 30-days readmission after RC for BC. Materials and methods: We relied on a collaborative database of 271 patients who underwent open RC for cT1-4a N0 M0 BC between January 2012 and December 2022. Univariable and multivariable binomial logistic regression analyses were performed to assess the odds ratio (OR) with 95% confidence intervals (CI) testing the ability of each serum marker to predict postoperative complications (any-grade and major complications), and 30-days unplanned readmission. Results: The median age at RC was 73 yr (IQR 67-79). A total of 182 (67.2%) patients were male and the median BMI was 25.2 (IQR 23.2-28.4). Overall, 172 (63.5%) patients had a Charlson Comorbidity Index (CCI) greater than 2 points and 98 (36.2%) were current smokers at the time of RC. Overall, 233 (86.0%) patients experienced at least one complication after RC. Of these, 171 (63.1%) patients had minor complications (Clavien-Dindo grade 1-2) while 100 (36.9%) experienced major complications (Clavien-Dindo grade ≥ 3). According to multivariable analysis, current smoking status, high plasma fibrinogen, and preoperative anemia were independently associated with major complications (OR 2.10, 95%CI 1.15-4.90, p = 0.02), (OR 1.51, 95%CI 1.26-1.98, p = 0.09), and (OR 1.35, 95%CI 1.17-2.57, p = 0.03), respectively. Overall, 56 (20.7%) patients experienced a 30-days unplanned readmission. According to univariable analysis, high preoperative CRP and hyperfibrinogenemia were significantly associated with an increased risk of unplanned readmission (OR 2.15, 95%CI 1.15-4.16, p = 0.02; OR 2.18, 95%CI 1.13-4.44, p = 0.02, respectively). Conclusions: In our study, the preoperative immune-inflammation signature described by NLR, PLR, LMR, SII, and CRP showed a low reliability in predicting perioperative course after RC. Preoperative anemia and hyperfibrinogenemia were independent predictors of major complications. Further studies are pending in order to draw definitive conclusions.

RESUMO

INTRODUCTION: Radical cystectomy and trimodal therapy are both accepted options in the management of muscle-invasive bladder cancer. As such, we sought to evaluate the micro-level costs associated with both modalities. METHODS: All patients undergoing trimodal therapy or radical cystectomy for primary treatment of urothelial muscle-invasive bladder cancer at a single academic center between 2008 and 2012 were included. Direct costs associated with each phase of a patient's clinical course were collected from the hospital's financial department, and physician costs were calculated based on the provincial fee schedule. Costs of radiation treatments were derived from previously published literature. RESULTS: A total of 137 patients were included. The mean (±SD) patient age was 69 (±12) years. Overall, 89 (65%) patients underwent radical cystectomy and 48 (35%) were treated with trimodal therapy. The radical cystectomy group had higher rates of cT3/T4 compared to those in the trimodal therapy group (51% vs 26%, P < .001). The median cost in the treatment phase for radical cystectomy was $30,577 (IQR: $23,908-$38,837) vs $18,979 ($17,271-$23,519) for trimodal therapy (P < .001). There was no significant difference between treatment groups with respect to cost of diagnosis or workup. However, the cost of follow-up care was numerically higher for patients undergoing trimodal therapy compared to radical cystectomy ($3,096/y vs $1,974/y, P = .09). CONCLUSIONS: In appropriately selected patients with muscle-invasive bladder cancer trimodal therapy costs are not prohibitive and are lower than in radical cystectomy. With increasing follow-up time after primary treatment, the cost difference between modalities may be mitigated by the need for bladder surveillance and salvage therapy in the trimodal therapy cohort.

RESUMO

OBJECTIVE: To determine the cost-effectiveness of mesh placement in patients undergoing ileal conduit urinary diversion for bladder cancer. Long-term studies have shown that parastomal hernias (PSH) occur in more than half of all stomas. Mesh prophylaxis has been shown to reduce PSH after end-colostomy and ileal conduits. However, no cost-effectiveness studies on mesh prophylaxis have been performed for this population. METHODS: We created a Markov model incorporating the costs and effectiveness of mesh prophylaxis for patients undergoing radical cystectomy and ileal conduit construction. Costs were obtained from the literature and adjusted to 2022 US dollars. Effectiveness was measured in quality-adjusted life years (QALY). 1- and 2-way sensitivity analyses were performed to test the robustness of our model. RESULTS: In stage I-IV bladder cancer, prophylactic mesh placement was costlier, but more effective in providing quality of life compared with no mesh placement at index surgery. Average incremental cost between the 2 strategies across all stages was an additional $897 when mesh was utilized. Incremental effectiveness averaged 0.49 additional QALY across all stages. This resulted in an incremental cost-effectiveness ratio of $2114.71/QALY. Sensitivity analyses indicated that benefit of mesh placement was sensitive to the probability of mesh infection. CONCLUSION: In patients undergoing ileal conduit urinary diversion for bladder cancer, mesh prophylaxis at the time of radical cystectomy is an overall cost-effective strategy in preventing PSH for patients presenting with all stages of bladder cancer.

RESUMO

AIMS: Approximately 75% of bladder cancer (BC) cases present as non-muscle-invasive BC (NMIBC). In patients with high-risk NMIBC, the mainstay treatment is intravesical Bacillus Calmette-Guérin (BCG), with immediate radical cystectomy (RC) as an alternative treatment option. The aim of the present study was to evaluate the cost-utility of BCG versus RC in patients with high-risk NMIBC from the UK healthcare payer perspective. MATERIALS AND METHODS: A six-state Markov model was developed that covered controlled disease, recurrence, progression to muscle-invasive BC, metastatic disease, and death. The model included adverse events of BCG and RC and monitoring and palliative care. Drug costs were obtained from the British National Formulary. Intravesical delivery, RC, and monitoring costs were sourced from the National Tariff Payment System and the literature. Utility data were obtained from the literature. Analyses were run over a 30-year time horizon, with future costs and effects discounted at 3.5% per annum. One-way and probabilistic sensitivity analyses were performed. RESULTS: The base case analysis comparing BCG with RC showed that BCG would increase life expectancy by 0.88 years versus RC, from 7.74 to 8.62 years. BCG resulted in an increase of 0.76 quality-adjusted life years (QALYs) versus RC, from 5.63 to 6.39 QALYs. Patients incurred lower lifetime costs if treated with BCG (£47,753) than with RC (£64,264). Cost savings were mainly driven by the lower cost of BCG versus RC, and palliative care costs. Sensitivity analyses showed that results were robust to assumptions. LIMITATIONS: The evidence base informing efficacy estimates of BCG is heterogeneous as different BCG administration schedules were reported in the literature, while incidence and cost data on some BCG-associated adverse events were sparse. CONCLUSIONS: Intravesical BCG led to increased QALYs and reduced costs versus RC for patients with high-risk NMIBC from the UK healthcare payer perspective.


Intravesical Bacillus Calmette-Guérin (BCG) is a recommended immunotherapy option for patients with high-risk non-muscle invasive bladder cancer (NMIBC) who have undergone transurethral resection of bladder tumor (TURBT). BCG is known for its high efficacy and good safety profile. However, current evidence on its effectiveness against other comparators such as radical cystectomy (RC) is limited, mainly because different BCG schedules are used, particularly with regard to maintenance therapy. Given this lack of evidence, we conducted the first cost-utility analysis which considers adequate BCG therapy relative to RC for the UK. We developed a Markov model that captured the effects of the intravesical BCG and RC on NMIBC, in addition to incidences of adverse events associated with either treatment. Costs of the two treatments, their administration, maintenance, and of treatments for adverse events were modelled alongside the quality-of-life effects of NMIBC, adverse events, and palliative care. We used published clinical data and UK cost data to inform our model. Our results show that BCG was associated with higher quality-adjusted life expectancy than RC and lower total costs from the healthcare system perspective. These results imply that adequate BCG immunotherapy is likely valuable for the National Healthcare System in terms of its effects on patients and indeed cost-saving relative to RC.

RESUMO

OBJECTIVES: To test for regional differences in total hospital costs (THC) across the United States in bladder cancer patients treated with open radical cystectomy (ORC) or robotic-assisted radical cystectomy (RARC). MATERIALS: We relied on the National Inpatient Sample (NIS) database (2016-2019) and stratified RC patients according to census region (Midwest, Northeast, South, West). Primary statistical analyses consisted of THC-trend analyses and multivariable log-link linear regression models, after adjustment for hospital clustering (Generalized Estimating Equation function) and discharge disposition weighting. Finally, sensitivity analysis, relying on most favorable patient cohort, was performed. RESULTS: Of 5280 eligible patients, 1441 (27%), 1031 (20%), 1854 (35%) and 954 (18%) underwent RC in the Midwest, Northeast, South and West, respectively. Median THC was 28,915$ and differed significantly between regions (Midwest: 28,105$; Northeast: 28,886$; South: 26,096$; West: 38,809$; p < 0.001). After stratification between ORC and RARC, highest THC was invariably recorded in the West: ORC 36,137$ vs 23,941-28,850$ and RARC 43,119$ vs 28,425-29,952$ (both p < 0.05). In multivariable log-link linear regression models, surgery in the West was independently associated with higher THC: ORC (Exponent beta [Exp[ß]]: 1.39; 95%-CI: 1.32-1.47; p < 0.001) and RARC (Exp[ß]: 1.46; 95%-CI: 1.38-1.55; p < 0.001). Results remained unchanged when analyses were refitted in most favorable patient subgroup. CONCLUSIONS: Important regional differences in ORC and RARC THC distinguish the West from other United States regions. The THC discrepancy clearly requires closer examination to identify underlying processes that contribute to inflated costs in the West.

RESUMO

BACKGROUND: Our study aims to assess the feasibility and the reproducibility of fluorescent confocal microscopy (FCM) real-time assessment of urethral and ureteral margins during open radical cystectomy (ORC) for bladder cancer (BCa). METHODS: From May 2020 to January 2022, 46 patients underwent ORC with intraoperative FCM evaluation. Each specimen was intraoperatively stained for histopathological analysis using FCM, analyzed as a frozen section (FSA), and sent for traditional H&E examination. Sensitivity, specificity, positive predictive value (PPV), and the negative predictive value (NPV) of FCM and FSA were assessed and compared with H&E for urethral and ureteral margins separately. RESULTS: The agreement was evaluated through Cohen's κ statistic. Urethral diagnostic agreement between FCM and FSA showed a κ = 0.776 (p < 0.001), while between FCM and H&E, the agreement was κ = 0.691 (p < 0.001). With regard to ureteral margins, an overall agreement of κ = 0.712 (p < 0.001) between FCM and FSA and of κ = 0.481 (p < 0.001) between FCM and H&E was found. CONCLUSIONS: FCM proved to be a safe, feasible, and reproducible method for the intraoperative assessment of urethral and ureteral margins during ORC. Compared to standard FSA, FCM showed adequate diagnostic performance in detecting urethral and ureteral malignant involvement.
