Transurethral En Bloc Resection Versus Standard Resection of Bladder Tumour: A Randomised, Multicentre, Phase 3 Trial. Eur Urol 2024:S0302-2838(24)02321-2. [PMID: 38692956 DOI: 10.1016/j.eururo.2024.04.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2024] [Revised: 03/25/2024] [Accepted: 04/10/2024] [Indexed: 05/03/2024]
Abstract
BACKGROUND Conventionally, standard resection (SR) is performed by resecting the bladder tumour in a piecemeal manner. En bloc resection of the bladder tumour (ERBT) has been proposed as an alternative technique in treating non-muscle-invasive bladder cancer (NMIBC). OBJECTIVE To investigate whether ERBT could improve the 1-yr recurrence rate of NMIBC, as compared with SR. DESIGN, SETTING, AND PARTICIPANTS A multicentre, randomised, phase 3 trial was conducted in Hong Kong. Adults with bladder tumour(s) of ≤3 cm were enrolled from April 2017 to December 2020, and followed up until 1 yr after surgery. INTERVENTION Patients were randomly assigned to receive either ERBT or SR in a 1:1 ratio. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The primary outcome was 1-yr recurrence rate. A modified intention-to-treat analysis on patients with histologically confirmed NMIBC was performed. The main secondary outcomes included detrusor muscle sampling rate, operative time, hospital stay, 30-d complications, any residual or upstaging of disease upon second-look transurethral resection, and 1-yr progression rate. RESULTS AND LIMITATIONS A total of 350 patients underwent randomisation, and 276 patients were histologically confirmed to have NMIBC. At 1 yr, 31 patients in the ERBT group and 46 in the SR group developed recurrence; the Kaplan-Meier estimate of 1-yr recurrence rates were 29% (95% confidence interval, 18-37) in the ERBT group and 38% (95% confidence interval, 28-46) in the SR group (p = 0.007). Upon a subgroup analysis, patients with 1-3 cm tumour, single tumour, Ta disease, or intermediate-risk NMIBC had a significant benefit from ERBT. None of the patients in the ERBT group and three patients in the SR group developed progression to muscle-invasive bladder cancer; the Kaplan-Meier estimates of 1-yr progression rates were 0% in the ERBT group and 2.6% (95% confidence interval, 0-5.5) in the SR group (p = 0.065). The median operative time was 28 min (interquartile range, 20-45) in the ERBT group and 22 min (interquartile range, 15-30) in the SR group (p < 0.001). All other secondary outcomes were similar in the two groups. CONCLUSIONS In patients with NMIBC of ≤3 cm, ERBT resulted in a significant reduction in the 1-yr recurrence rate when compared with SR (funded by GRF/ECS, RGC, reference no.: 24116518; ClinicalTrials.gov number, NCT02993211). PATIENT SUMMARY Conventionally, non-muscle-invasive bladder cancer is treated by resecting the bladder tumour in a piecemeal manner. In this study, we found that en bloc resection, that is, removal of the bladder tumour in one piece, could reduce the 1-yr recurrence rate of non-muscle-invasive bladder cancer.

Achieving Benchmarks for National Quality Indicators Reduces Recurrence and Progression in Non-muscle-invasive Bladder Cancer. Eur Urol Oncol 2024:S2588-9311(24)00037-3. [PMID: 38296735 DOI: 10.1016/j.euo.2024.01.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2023] [Revised: 12/04/2023] [Accepted: 01/04/2024] [Indexed: 02/02/2024]
Abstract
BACKGROUND Noncompliance with evidence-based interventions and guidelines contributes to significant and variable recurrence and progression in patients with non-muscle-invasive bladder cancer (NMIBC). The implementation of a quality performance indicator (QPI) programme in Scotland's National Health Service (NHS) aimed to improve cancer outcomes and reduce nationwide variance. OBJECTIVE To evaluate the effect of hospitals achieving benchmarks for two specific QPIs on time to recurrence and progression in NMIBC. DESIGN, SETTING, AND PARTICIPANTS QPIs for bladder cancer (BC) were enforced nationally in April 2014. NHS health boards collected prospective data on all new BC patients. Prospectively recorded surveillance data were pooled from 12 collaborating centres. INTERVENTION QPIs of interest were (1) hospitals achieving detrusor muscle (DM) sampling target at initial transurethral resection of bladder tumour (TURBT) and (2) use of single instillation of mitomycin C after TURBT (SI-MMC). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The primary and secondary endpoints were time to recurrence and progression, respectively. Kaplan-Meier and Cox multivariable regression analyses were performed. KEY FINDINGS AND LIMITATIONS Between April 1, 2014 and March 31, 2017, we diagnosed 3899 patients with new BC, of which 2688 were NMIBC . With a median follow up of 60.3 mo, hospitals achieving the DM sampling target had a 5.4% lower recurrence rate at 5 yr than hospitals not achieving this target (442/1136 [38.9%] vs 677/1528 [44.3%], 95% confidence interval [CI] = 1.6-9.2, p = 0.005). SI-MMC was associated with a 20.4% lower recurrence rate (634/1791 [35.4%] vs 469/840 [55.8%], 95% CI = 16.4-24.5, p < 0.001). On Cox multivariable regression, meeting the DM target and SI-MMC were associated with significant improvement in recurrence (hazard ratio [HR] 0.81, 95% CI = 0.73-0.91, p = 0.0002 and HR 0.66, 95% CI = 0.59-0.74, p < 0.004, respectively) as well as progression-free survival (HR 0.62, 95% CI = 0.45-0.84, p = 0.002 and HR 0.65, 95% CI = 0.49-0.87, p = 0.004, respectively). We did not have a national multicentre pre-QPI control. CONCLUSIONS Within a national QPI programme, meeting targets for sampling DM and SI-MMC in the real world were independently associated with delays to recurrence and progression in NMIBC patients. PATIENT SUMMARY Following the first 3 yr of implementing a novel quality performance indicator programme in Scotland, we evaluated compliance and outcomes in non-muscle-invasive bladder cancer. In 2688 patients followed up for 5 yr, we found that achieving targets for sampling detrusor muscle and the single instillation of mitomycin C during and after transurethral resection of bladder tumour, respectively, were associated with delays in cancer recurrence and progression.

Surgical treatment of urachal remnants in an adult population-a single-centre experience. Ir J Med Sci 2023; 192:3023-3027. [PMID: 36935447 PMCID: PMC10692245 DOI: 10.1007/s11845-023-03339-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Accepted: 03/03/2023] [Indexed: 03/21/2023]
Abstract
BACKGROUND Urachal remnants are a rare congenital defect resulting from failure of obliteration of a fibrous tube that connects the umbilicus to the bladder dome during embryological development. Oftentimes a urachal remnant will go undiagnosed, but occasionally a patient may present with a variety of symptoms, ultimately leading to the identification of the remnant. Given its rarity, there is very limited literature available on the management of symptomatic urachal remnants, especially in adults. Surgical resection has been the first-line management of urachal remnants for years, especially given the risk of the development of urachal adenocarcinoma secondary to recurrent infection, persistent irritation, and urinary stasis associated with some urachal remnants. AIM We present our experience in the management of symptomatic urachal remnants in adults at our institute and perform a brief literature review of the same. METHODS A retrospective review of all cases who underwent surgical management of symptomatic urachal remnants between December 2015 and January 2022 was performed. Seven cases of urachal remnant excision in total were identified over the time period. Patient characteristics and perioperative parameters were analysed. Post-operative complications were measured in accordance with the Clavien-Dindo grading system. RESULT In total, 7 cases of urachal remnants were treated at our institute over the study period. Four patients were treated with a TURBT and 3 patients were treated with a laparoscopic partial cystectomy. There were no intraoperative complications and one post-operative complication requiring readmission for intravenous antibiotics. There was one mortality but this was not as a direct result of the operative procedure. Mean length of stay was 1.71 days. Two of patients had histologically confirmed urachal adenocarcinoma and the remaining five patients had benign histology. Each patient was seen in the outpatients department 6 weeks post-operatively for clinical review and review of histology. No further follow-up was required for the patients with benign histology given resolution of symptoms and follow-up for the malignant histology was arranged appropriately following MDM. CONCLUSION There is a paucity of data available on the management of urachal remnants in the adult population; however, an endoscopic or laparoscopic approach is a safe and effective method of excising symptomatic urachal remnants.

Photodynamic Diagnosis-guided Transurethral Resection of Bladder Tumour in Participants with a First Suspected Diagnosis of Intermediate- or High-risk Non-muscle-invasive Bladder Cancer: Cost-effectiveness Analysis Alongside a Randomised Controlled Trial. EUR UROL SUPPL 2023; 53:67-77. [PMID: 37441343 PMCID: PMC10334235 DOI: 10.1016/j.euros.2023.05.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 05/12/2023] [Indexed: 07/15/2023] Open
Abstract
Background Recurrence of non-muscle-invasive bladder cancer (NMIBC) is common after transurethral resection of bladder tumour (TURBT). Photodynamic diagnosis (PDD) may reduce recurrence. PDD uses a photosensitiser in the bladder that causes the tumour to fluoresce to guide resection. PDD provides better diagnostic accuracy and allows more complete tumour resection. Objective To estimate the economic efficiency of PDD-guided TURBT (PDD-TURBT) in comparison to white light-guided TURNT (WL-TURBT) in individuals with a suspected first diagnosis of NMIBC at intermediate or high risk of recurrence on the basis of routine visual assessment before being scheduled for TURBT. Design setting and participants This is a health economic evaluation alongside a pragmatic, open-label, parallel-group randomised trial from a societal perspective. A total of 493 participants (aged ≥16 yr) were randomly allocated to PDD-TURBT (n = 244) or WL-TURBT (n = 249) in 22 UK National Health Service hospitals. Outcome measurements and statistical analysis Cost effectiveness ratios were based on the use of health care resources associated with PDD-TURBT and WL-TURBT and quality-adjusted life years (QALYs) gained within the trial. Uncertainties in key parameters were assessed using sensitivity analyses. Results and limitations On the basis of the use of resources driven by the trial protocol, the incremental cost effectiveness of PDD-TURBT in comparison to WL-TURBT was not cost saving. At 3 yr, the total cost was £12 881 for PDD-TURBT and £12 005 for WL-TURBT. QALYs at three years were 2.087 for PDD-TURBT and 2.094 for WL-TURBT. The probability that PDD-TURBT is cost effective was never >30% above the range of societal cost-effectiveness thresholds. Conclusions There was no evidence of a difference in either costs or QALYs over 3-yr follow-up between PDD-TURBT and WL-TURBT in individuals with suspected intermediate- or high-risk NMIBC. PDD-TURBT is not supported for the management of primary intermediate- or high-risk NMIBC. Patient summary We assessed overall costs for two approaches for removal of bladder tumours in noninvasive cancer and measured quality-adjusted life years gained for each. We found that use of a photosensitiser in the bladder was not more cost effective than use of white light only during tumour removal.

Potential Carbon Savings with Day-case Compared to Inpatient Transurethral Resection of Bladder Tumour Surgery in England: A Retrospective Observational Study Using Administrative Data. EUR UROL SUPPL 2023; 52:44-50. [PMID: 37284039 PMCID: PMC10240513 DOI: 10.1016/j.euros.2023.03.007] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/29/2023] [Indexed: 06/08/2023] Open
Abstract
Background The National Health Service (NHS) in England has set a net-zero target for carbon emissions by 2040. Increasing use of day-case surgery pathways may help in meeting this target. Objective To investigate the estimated difference in carbon footprint between day-case and inpatient transurethral resection of bladder tumour (TURBT) surgery in England. Design setting and participants This was a retrospective analysis of administrative data extracted from the Hospital Episode Statistics database for all TURBT procedures conducted in England from April 1, 2013 to March 31, 2022. Outcome measurements and statistical analysis Day-case and inpatient TURBT procedures were identified and the carbon footprint for key elements of the surgical pathway was estimated using data from Greener NHS and the Sustainable Healthcare Coalition. Results and limitations Of 209 269 TURBT procedures identified, 41 583 (20%) were classified as day-case surgery. The day-case rate increased from 13% in 2013-2014 to 31% in 2021-2022. The move from inpatient stays to day-case surgery between 2013-2014 and 2021-2022 demonstrates a trend toward a lower-carbon pathway, with an estimated saving of 2.9 million kg CO2 equivalents (equivalent to powering 2716 homes for 1 yr) in comparison to no change in practice. We calculated that potential carbon savings for the financial year 2021-2022 would be 217 599 kg CO2 equivalents (equivalent to powering 198 homes for 1 yr) if all hospitals in England not already in the upper quartile were able to achieve the current upper-quartile day-case rate. Our study is limited in that estimates are based on carbon factors for generic surgical pathways. Conclusions Our study highlights potential NHS carbon savings that could be achieved by moving from inpatient stays to day-case surgery. Reducing variation in care across the NHS and encouraging all hospitals to adopt day-case surgeries, where clinically appropriate, would lead to further carbon savings. Patient summary In this study we estimated the potential for carbon savings if patient undergoing bladder tumour surgery were admitted and discharged on the same day. We estimate that increasing use of day-case surgery between 2013-2014 and 2021-2022 has saved 2.9 million kg CO2 equivalents. If all hospitals were to achieve day case-rates comparable to those in the highest quarter of hospitals in England in 2021-2022, then the carbon equivalent to powering 198 homes for 1 year could have been saved.

Efficacy and safety of transurethral resection of bladder tumour combined with chemotherapy and immunotherapy in bladder-sparing therapy in patients with T1 high-grade or T2 bladder cancer: a protocol for a randomized controlled trial. BMC Cancer 2023; 23:320. [PMID: 37024824 PMCID: PMC10080830 DOI: 10.1186/s12885-023-10798-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Accepted: 03/31/2023] [Indexed: 04/08/2023] Open
Abstract
BACKGROUND Bladder cancer is the tenth most common cancer worldwide. For patients with T1 high-grade or T2 bladder cancer, radical cystectomy is recommended. However, radical cystectomy is associated with various complications and has a detrimental impact on the quality of life. Bladder-sparing therapy has been widely explored in patients with muscle-invasive bladder cancer, and whether a combination of transurethral resection of bladder tumour (TURBT) with chemotherapy and immunotherapy shows definite superiority over TURBT plus chemotherapy is still a matter of debate. The aim of this study is to investigate the efficacy and safety of TURBT combined with chemotherapy and immunotherapy in bladder-sparing therapy in patients with T1 high-grade or T2 bladder cancer who are unwilling or unsuitable to undergo radical cystectomy. METHODS An open-label, multi-institutional, two-armed randomized controlled study will be performed with 86 patients with T1 high-grade or T2 bladder cancer meeting the eligibility criteria. Participants in the experimental group (n = 43) will receive TURBT combined with chemotherapy (GC: gemcitabine 1000 mg/m2 on the 1st day and the 8th day, cisplatin 70 mg/m2 on the 2nd day, repeated every 21 days) and immunotherapy (toripalimab 240 mg on the 5th day, repeated every 21 days), and those in the control group (n = 43) will receive TURBT plus chemotherapy (GC). The primary outcome is pathological response, and the secondary outcomes include progression-free survival, overall survival, toxicities, and quality of life. DISCUSSION To the best of our knowledge, this is the first study to evaluate the efficacy and safety of TURBT combined with GC regimen and toripalimab in bladder-sparing therapy in patients with T1 high-grade or T2 bladder cancer. The expected benefit is that the combination of TURBT with chemotherapy and immunotherapy would be more effective than TURBT plus chemotherapy without compromising the quality of life and increasing the toxicity.

Comparison between 5-aminolevulinic acid photodynamic diagnosis and narrow-band imaging for bladder cancer detection. BMC Urol 2021; 21:180. [PMID: 34937543 PMCID: PMC8693495 DOI: 10.1186/s12894-021-00946-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2021] [Accepted: 12/14/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND To compare 5-aminolevulinic acid (5-ALA)-mediated photodynamic diagnosis (PDD) with narrow-band imaging (NBI) for cancer detection during transurethral resection of bladder tumour (TURBT). METHODS Between June 2018 and October 2020, 114 patients and 282 lesions were included in the analysis. Patients were orally administered 5-ALA (20 mg/kg) 2 h before TURBT. The bladder was inspected with white light (WL), PDD, and NBI for each patient, and all areas positive by at least one method were resected or biopsied. The imaging data were then compared to the pathology results. RESULTS The sensitivities of WL, PDD, and NBI for detecting urothelial carcinoma were 88.1%, 89.6%, and 76.2%, respectively. The specificity, positive predictive value, and negative predictive value for detecting urothelial carcinoma were 47.5%, 80.9%, and 61.3%, respectively, for WL; 22.5%, 74.5%, and 46.2%, respectively, for PDD; and 46.3%, 78.2%, and 43.5%, respectively, for NBI. PDD was significantly more sensitive than NBI for all lesions (p < 0.001) and carcinoma in situ (CIS) lesions (94.6% vs. 54.1%, p < 0.001). CONCLUSIONS PDD can increase the detection rate of bladder cancer, compared to NBI, by greater than 10%. Therefore, 100% of CIS lesions can be detected by adding PDD to WL.

Conventional white light imaging-assisted transurethral resection of bladder tumour (TURBT) versus IMAGE1S-assisted TURBT in non-muscle-invasive bladder cancer patients: trial protocol and 18 months results. World J Urol 2021; 40:727-738.

Abstract
PURPOSE White light (WL) is the traditional imaging modality for transurethral resection of bladder tumour (TURBT). IMAGE1S is a likely addition. We compare 18-mo recurrence rates following TURBT using IMAGE1S versus WL guidance. METHODS Twelve international centers conducted a single-blinded randomized controlled trial. Patients with primary and recurrent non-muscle-invasive bladder cancer (NMIBC) were randomly assigned 1:1 to TURBT guided by IMAGE1S or WL. Eighteen-month recurrence rates and subanalysis for primary/recurrent and risk groups were planned and compared by chi-square tests and survival analyses. RESULTS 689 patients were randomized for WL-assisted (n = 354) or IMAGE1S-assisted (n = 335) TURBT. Of these, 64.7% had a primary tumor, 35.3% a recurrent tumor, and 4.8%, 69.2% and 26.0% a low-, intermediate-, and high-risk tumor, respectively. Overall, 60 and 65 patients, respectively, completed 18-mo follow-up, with recurrence rates of 31.0% and 25.4%, respectively (p = 0.199). In patients with primary, low-/intermediate-risk tumors, recurrence rates at 18-mo were significantly higher in the WL group compared with the IMAGE1S group (31.9% and 22.3%, respectively: p 0.035). Frequency and severity of adverse events were comparable in both treatment groups. Immediate and adjuvant intravesical instillation therapy did not differ between the groups. Potential limitations included lack of uniformity of surgical resection, central pathology review, and missing data. CONCLUSION There was not difference in the overall recurrence rates between IMAGE1S and WL assistance 18-mo after TURBT in patients with NMIBC. However, IMAGE1S-assisted TURBT considerably reduced the likelihood of disease recurrence in primary, low/intermediate risk patients.

Comparing an Imaging-guided Pathway with the Standard Pathway for Staging Muscle-invasive Bladder Cancer: Preliminary Data from the BladderPath Study. Eur Urol 2021; 80:12-15. [PMID: 33653635 DOI: 10.1016/j.eururo.2021.02.021] [Citation(s) in RCA: 23] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2020] [Accepted: 02/12/2021] [Indexed: 11/23/2022]
Abstract
Transurethral resection of bladder tumour (TURBT) is central to the diagnosis of muscle-invasive bladder cancer (MIBC). With the oncological safety of TURBT unknown, staging inaccuracies commonplace, and correct treatment of MIBC potentially delayed, multiparametric magnetic resonance imaging (mpMRI) may offer rapid, accurate, and noninvasive diagnosis of MIBC. BladderPath is a randomised trial comparing risk-stratified (5-point Likert scale) image-directed care with TURBT for patients with newly diagnosed BC. To date, we have screened 279 patients and randomised 113. Here we report on the first 100 participants to complete staging: 48 in pathway 1 (TURBT) and 52 in pathway 2 (mpMRI for possible MIBC, Likert 3-5). Fifty of 52 participants designated Likert 1-2 (probable NMIBC) from both pathways were confirmed as having NMIBC (96%). Ten of 11 cases diagnosed as NMIBC by mpMRI have been pathologically confirmed as NMIBC, and 10/15 cases diagnosed as MIBC by mpMRI have been treated as MIBC (5 participants underwent TURBT). The specificity of mpMRI for identification of MIBC remains a limitation. These initial experiences indicate that it is feasible to direct possible MIBC patients to mpMRI for staging instead of TURBT. Furthermore, a 5-point Likert scale accurately identifies patients with low risk of MIBC (Likert 1-2), and flexible cystoscopy biopsies appear sufficient for diagnosing BC. PATIENT SUMMARY: We are conducting a clinical trial to assess whether some bladder tumour surgery can be replaced by magnetic resonance imaging scans to determine the stage of the cancer in patients whose tumours appear to be invasive. Our early data suggest that this approach is feasible. The data also show that using a visual score ('Likert scale') can help to identify bladder tumours that are very unlikely to be invasive, and that taking a biopsy in the outpatient clinic when first inspecting the bladder via a camera (diagnostic flexible cystoscopy) is useful for confirming bladder cancer.

Abstract
We report a 48-year-old fit and healthy woman who was incidentally diagnosed to have adenocarcinoma of gallbladder after laparoscopic cholecystectomy. Subsequent imaging showed no evidence of regional or distant spread. She was scheduled for elective laparotomy and resection of gallbladder bed, but during laparotomy frozen section analysis of an incidentally discovered peritoneal deposit confirmed metastasis, so the procedure was abandoned. Thereafter, she received cisplatin and gemcitabine chemotherapy. However, surveillance computed tomography incidentally noted a urinary bladder mass which had not been present before. Transurethral resection of the bladder lesion revealed moderately differentiated adenocarcinoma of urinary bladder. The appearance and immunoprofile of the lesion confirmed metastasis from the primary gallbladder cancer, which has not been documented in the literature to the best of our knowledge. Her disease progressed and she is being challenged with gemcitabine and carboplatin as second-line palliative chemotherapy. She is still alive two years after the initial diagnosis.

Enhanced Quality and Effectiveness of Transurethral Resection of Bladder Tumour in Non-muscle-invasive Bladder Cancer: A Multicentre Real-world Experience from Scotland's Quality Performance Indicators Programme. Eur Urol 2020; 78:520-530. [PMID: 32690321 DOI: 10.1016/j.eururo.2020.06.051] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2020] [Accepted: 06/22/2020] [Indexed: 11/25/2022]
Abstract
BACKGROUND Clinical outcomes from non-muscle-invasive bladder cancer (NMIBC) are partly determined by the quality of initial interventions. To improve and standardise treatment for cancer, Scotland implemented a national Quality Performance Indicator (QPI) programme for bladder cancer (BC). OBJECTIVE To evaluate compliance with specific quality indicators (QIs) related to transurethral resection of bladder tumour (TURBT) and to understand clinical outcomes from NMIBC following the introduction of the QPI programme. DESIGN, SETTING, AND PARTICIPANTS Within a robust governance framework, 12 mandatory evidence-based QPIs were implemented nationally in April 2014. We report prospectively collected data for all new BC patients (between April 2014 and March 2017). We include follow-up data for 2689 patients. INTERVENTION The TURBT-related QPIs were (1) using a bladder diagram, (2) single post-TURBT instillation of mitomycin C (SPI-MMC), (3) detrusor muscle (DM) in the specimen, and (4) early re-TURBT in high-risk NMIBC. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS We measured compliance with these QPIs and (1) recurrence rate at first follow-up cystoscopy (RRFFC), (2) rates of residual cancer, and (3) pT2 cancer at re-TURBT. Associations between QPI compliance, tumour features, and outcomes were assessed with multivariable logistic regression models. RESULTS AND LIMITATIONS Among 4246 new BC patients, SPI-MMC was used in 67% (2029/3023) NMIBC patients. In 1860 NMIBC patients undergoing TURBT, RRFFC, rate of residual cancer, and rate of pT2 at re-TURBT were 13% (116/888), 33% (212/653), and 2.9% (19/653), respectively. SPI-MMC was associated with lower RRFFC, independent of all variables including hospital volume and surgeon. Presence of DM in the specimen halved the likelihood of residual disease in pT1 cancers. The main limitation is the lack of a pre-QPI introduction cohort for comparison. CONCLUSIONS The implementation of a QI programme in Scotland appears to facilitate high-quality TURBT, which in a real-world setting is associated with low early recurrence/residual cancer and accurate pathological staging. PATIENT SUMMARY Following the first 3 yr of implementing a novel Quality Performance Indicator (QPI) programme in Scotland, we assessed compliance and outcomes in non-muscle-invasive bladder cancer. Evaluating over 4000 new bladder cancer patients, we found that the QPI programme was associated with low recurrence and accurate staging following the initial transurethral resection of bladder tumour.

Best Practices to Optimise Quality and Outcomes of Transurethral Resection of Bladder Tumours. Eur Urol Oncol 2020; 4:12-19. [PMID: 32684515 DOI: 10.1016/j.euo.2020.06.010] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2020] [Revised: 06/17/2020] [Accepted: 06/28/2020] [Indexed: 11/21/2022]
Abstract
CONTEXT Transurethral resection of bladder tumour (TURBT) for bladder cancer (BC) is an underappreciated common urological procedure. TURBT outcomes are highly variable, and results are dependent on judgement and surgical skill. OBJECTIVE To perform a narrative review and identify optimal best practice in TURBT including preparation, choice of equipment, procedural steps, surgical technique, and management of difficult scenarios and complications. EVIDENCE ACQUISITION Medline, Embase, and the Cochrane Central Register of Controlled Trials were searched. Important studies were identified and reviewed by an international panel of urologists representing major urological societies and guideline panels with a record of academic publication in this field. In areas where the group identified a lack of evidence or agreement, discussions took place until a consensus was reached. EVIDENCE SYNTHESIS A total of 814 studies were identified and 43 were included. The majority were retrospective (level of evidence 3), with only two prospective randomised trials. Four broad themes were identified, which formed the basis for the review: (1) the role of TURBT within the overall management of BC, (2) TURBT techniques, (3) measurement of outcomes including quality control and checklists, and (4) postoperative management. Familiarity with all aspects of the procedure is necessary to minimise morbidity and improve oncological outcomes. Development of new instruments and techniques, and prospective audit of TURBT outcomes are important future goals. CONCLUSIONS TURBT is a common and challenging operation with known variable outcomes. To reduce these variations and optimise outcomes, best practice based on evidence and expert opinion is recommended. PATIENT SUMMARY Transurethral resection of bladder tumour (TURBT) is a common but deceptively difficult urological operation. Optimal outcomes depend on experience and surgical skill. An international group of experienced TURBT surgeons review critical aspects of the procedure and share best practice to stimulate further discussion.

An International Collaborative Consensus Statement on En Bloc Resection of Bladder Tumour Incorporating Two Systematic Reviews, a Two-round Delphi Survey, and a Consensus Meeting. Eur Urol 2020; 78:546-569. [PMID: 32389447 DOI: 10.1016/j.eururo.2020.04.059] [Citation(s) in RCA: 45] [Impact Index Per Article: 11.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2020] [Accepted: 04/22/2020] [Indexed: 11/29/2022]
Abstract
BACKGROUND There has been increasing interest in en bloc resection of bladder tumour (ERBT) as an oncologically noninferior alternative to transurethral resection of bladder tumour (TURBT) with fewer complications and better histology specimens. However, there is a lack of robust randomised controlled trial (RCT) data for making recommendations. OBJECTIVE We aimed to develop a consensus statement to standardise various aspects of ERBT for clinical practice and to guide future research. DESIGN, SETTING, AND PARTICIPANTS We developed the consensus statement on ERBT using a modified Delphi method. First, two systematic reviews were performed to investigate the clinical effectiveness of ERBT versus TURBT (effectiveness review) and to identify areas of uncertainty in ERBT (uncertainties review). Next, 200 health care professionals (urologists, oncologists, and pathologists) with experience in ERBT were invited to complete a two-round Delphi survey. Finally, a 16-member consensus panel meeting was held to review, discuss, and re-vote on the statements as appropriate. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Meta-analyses were performed for RCT data in the effectiveness review. Consensus statements were developed from the uncertainties review. Consensus was defined as follows: (1) ≥70% scoring a statement 7-9 and ≤15% scoring the statement 1-3 (consensus agree), or (2) ≥70% scoring a statement 1-3 and ≤15% scoring the statement 7-9 (consensus disagree). RESULTS AND LIMITATIONS A total of 10 RCTs were identified upon systematic review. ERBT had a shorter irrigation time (mean difference -7.24 h, 95% confidence interval [CI] -9.29 to -5.20, I2 = 85%, p < 0.001) and a lower rate of bladder perforation (risk ratio 0.30, 95% CI 0.11-0.83, I2 = 1%, p = 0.02) than TURBT, both with moderate certainty of evidence. There were no significant differences in recurrences at 0-12, 13-24, or 25-36 mo (all very low certainty of evidence). A total of 103 statements were developed, of which 99 reached a consensus. A summary of statements is as follows: ERBT should always be considered for treating non-muscle-invasive bladder cancer; ERBT should be considered feasible even for bladder tumours larger than 3 cm; number and location of bladder tumours are not major limitations in performing ERBT; the planned circumferential margin should be at least 5 mm from any visible bladder tumour; after ERBT, additional biopsy of the tumour edge or tumour base should not be performed routinely; for the ERBT specimen, T1 substage, and circumferential and deep resection margins must be assessed; it is safe to give a single dose of immediate intravesical chemotherapy, perform second-look transurethral resection, and give intravesical bacillus Calmette-Guérin (BCG) therapy after ERBT; and in studies of ERBT, both per-patient and -tumour analysis should be performed for different outcomes as appropriate. Important outcomes for future ERBT studies were also identified. A limitation is that as consensus statements are brief, concise and binary in nature, areas of uncertainty that are complex in nature may not be addressed adequately. CONCLUSIONS We have provided the most comprehensive review of the evidence base to date using a meta-analysis where appropriate and applying the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology, and mobilised the international urology community to develop a consensus statement on ERBT using transparent and robust methods. The consensus statement will provide interim guidance for health care professionals who practice ERBT and inform researchers regarding ERBT-related studies in the future. PATIENT SUMMARY En bloc resection of bladder tumour (ERBT) is a surgical technique aiming to resect a bladder tumour in one piece. We included an international panel of experts to agree on the best practice of ERBT, and this will provide guidance to clinicians and researchers in the future.

Case report: A rare case of extravesical, extraperitoneal metastasis after transuretheral resection of urothelial carcinoma. Urol Case Rep 2020; 29:101017. [PMID: 31867214 PMCID: PMC6906667 DOI: 10.1016/j.eucr.2019.101017] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2019] [Revised: 09/12/2019] [Accepted: 09/17/2019] [Indexed: 10/28/2022] Open
Abstract
Bladder perforation secondary to transurethral resection of bladder tumour (TURBT) increases the risk of tumour cell seeding and eventual extravesical metastasis. Here we presented a case where a patient with localised bladder tumour was initially managed with repeated TURBTs for tumour recurrence. Subsequently he was found to have extravesical pelvic metastasis. This was likely secondary to microperforation of bladder and tumour cell seeding. Microscopic bladder perforation is difficult to diagnose. However patients with confirmed bladder perforation during TURBT would justify systemic radiological cancer surveillance in view of higher risk of metastatic disease.

Impact of double J stenting or nephrostomy placement during transurethral resection of bladder tumour on the incidence of metachronous upper urinary tract urothelial cancer. BMC Cancer 2020; 20:140. [PMID: 32085750 PMCID: PMC7035650 DOI: 10.1186/s12885-020-6620-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2019] [Accepted: 02/11/2020] [Indexed: 12/03/2022] Open
Abstract
Background Whether or not double J (DJ) stenting during transurethral resection of a bladder tumour (TURBT) harms patients with regard to possible metachronous upper urinary tract urothelial cancer (UUTUC) development remains controversial. This study evaluated the impact of DJ compared to nephrostomy placement during TURBT for bladder cancer (BCa) on the incidence of metachronous UUTUCs. Methods We retrospectively analysed 637 patients who underwent TURBT in our department between 2008 and 2016. BCa, UUTUC and urinary drainage data (retrograde/anterograde DJ and percutaneous nephrostomy) were assessed, along with the prevalence of hydronephrosis, and mortality. Chi-square and Fisher’s exact test was performed for univariate analyses. Survival analysis was performed by the Kaplan-Meier method and log-rank tests. Results UUTUC was noted in 28 out of 637 patients (4.4%), whereas only eight (1.3%) developed it metachronously to BCa. Out of these, four patients received DJ stents, while four patients received no urinary drainage of the upper urinary tract. Placement of urinary drainage significantly correlated with UUTUC (50.0% vs. 17.9%; p = 0.041). DJ stenting significantly correlated with UUTUC (50.0% vs. 11%; p < 0.01), while no patient with a nephrostomy tube developed UUTUC. UUTUC-free survival rates were significantly lower for patients with DJ stents than for all other patients (p = 0.001). Patients with or without DJ stents had similar overall survival (OS) rates (p = 0.73), whereas patients with nephrostomy tubes had significantly lower OS rates than all other patients (p < 0.001). Conclusions Patients with DJ stenting during TURBT for BCa might have an increased risk of developing metachronous UUTUC. This study indicated advantages in placing nephrostomy tubes rather than DJ stents; however, confirmation requires investigation of a larger cohort. Even so, the increased mortality rate in the nephrostomy group reflected hydronephrosis as an unfavourable prognostic factor.

Retrospective study of various conservative treatment options with bacille Calmette-Guérin in bladder urothelial carcinoma T1G3: Maintenance therapy. Actas Urol Esp 2016; 40:370-7. [PMID: 26922518 DOI: 10.1016/j.acuro.2015.12.009] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2015] [Revised: 12/11/2015] [Accepted: 12/14/2015] [Indexed: 10/22/2022]
Abstract
OBJECTIVE To compare various conservative treatment options for high-grade T1 nonmuscle-invasive bladder cancer (NMIBC). Bacille Calmette-Guérin (BCG) is the preferred intravesical treatment for high-grade T1 tumours; however, a number of experts still question the need for maintenance BCG. MATERIAL AND METHODS We retrospectively analysed data from 1039 patients with primary and recurrent T1G3 NMIBC. All patients underwent complete transurethral resection of the bladder tumour (TURBT), with muscle in the sample and multiple bladder biopsies. The patients were treated with the following: only one initial TURBT (n=108), re-TURBT (n=153), induction with 27mg of BCG (Connaught strain) (n=87), induction with 81mg of BCG (n=489) or induction with 81mg of BCG+maintenance (n=202). The time to first recurrence, progression (to T2 or greater or to metastatic disease) and specific mortality of the disease was assessed using the Kaplan-Meier survival function and were compared using the log-rank test and the Cox multivariate regression model of proportional risks. RESULTS The mean follow-up was 62±39 months. The risk of recurrence was significantly lower for the patients treated with maintenance therapy of 81mg of BCG than in the other treatment groups (P<.001). The risk of tumour progression was also significantly lower for the patients treated with maintenance BCG than for the patients treated only with one TURBT, re-TURBT and with induction therapy with 27mg of BCG (P=.0003). The specific disease mortality was significantly lower with BCG maintenance (9.4%) than with only one TURBT (27.8%; P=.003). CONCLUSIONS In the case of T1G3 NMIBC, a complete dose of BCG with maintenance is associated with better recurrence results than are other conservative treatment modalities. The results of progression and survival specific to the disease were also better with induction BCG, with or without maintenance.

The Clinical Research Office of the Endourological Society (CROES) Multicentre Randomised Trial of Narrow Band Imaging-Assisted Transurethral Resection of Bladder Tumour (TURBT) Versus Conventional White Light Imaging-Assisted TURBT in Primary Non-Muscle-invasive Bladder Cancer Patients: Trial Protocol and 1-year Results. Eur Urol 2016; 70:506-15. [PMID: 27117749 DOI: 10.1016/j.eururo.2016.03.053] [Citation(s) in RCA: 101] [Impact Index Per Article: 12.6] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2016] [Accepted: 03/31/2016] [Indexed: 11/23/2022]
Abstract
BACKGROUND White light (WL) is the established imaging modality for transurethral resection of bladder tumour (TURBT). Narrow band imaging (NBI) is a promising addition. OBJECTIVES To compare 12-mo recurrence rates following TURBT using NBI versus WL guidance. DESIGN, SETTING, AND PARTICIPANTS The Clinical Research Office of the Endourological Society (CROES) conducted a prospective randomised single-blind multicentre study. Patients with primary non-muscle-invasive bladder cancer (NMIBC) were randomly assigned 1:1 to TURBT guided by NBI or WL. INTERVENTION TURBT for NMIBC using NBI or WL. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Twelve-month recurrence rates were compared by chi-square tests and survival analyses. RESULTS AND LIMITATIONS Of the 965 patients enrolled in the study, 481 patients underwent WL-assisted TURBT and 484 patients received NBI-assisted TURBT. Of these, 294 and 303 patients, respectively, completed 12-mo follow-up, with recurrence rates of 27.1% and 25.4%, respectively (p=0.585, intention-to-treat [ITT] analysis). In patients at low risk for disease recurrence, recurrence rates at 12 mo were significantly higher in the WL group compared with the NBI group (27.3% vs 5.6%; p=0.002, ITT analysis). Although TURBT took longer on average with NBI plus WL compared with WL alone (38.1 vs 35.0min, p=0.039, ITT; 39.1 vs 35.7min, p=0.047, per protocol [PP] analysis), lesions were significantly more often visible with NBI than with WL (p=0.033). Frequency and severity of adverse events were similar in both treatment groups. Possible limitations were lack of uniformity of surgical resection, data on smoking status, central pathology review, and specific data regarding adjuvant intravesical instillation therapy. CONCLUSIONS NBI and WL guidance achieved similar overall recurrence rates 12 mo after TURBT in patients with NMIBC. NBI-assisted TURBT significantly reduced the likelihood of disease recurrence in low-risk patients. PATIENT SUMMARY Use of a narrow band imaging technique might provide greater detection of bladder tumours and subsequent treatment leading to reduced recurrence in low-risk patients.
