Abstract
BACKGROUND Identification of patient subclasses that correlate with the diagnostic performance of photodynamic diagnostic (PDD)-assisted transurethral resection of bladder tumors (TURBT) may improve outcomes. METHODS Data were extracted from patients that underwent PDD-assisted TURBT at the University of Tsukuba Hospital between 2018 and 2023. Sensitivity and specificity were evaluated based on PDD findings (excluding WL findings) and pathology results. Cluster analysis using uniform manifold approximation and projection and k-means methods was performed, focusing on patients with malignant lesions. RESULTS A total of 267 patients and 2082 specimens were extracted. Sensitivity was lowest with regard to BCG treatment (53.7 %), followed by flat lesions (57.2 %), urine cytology class ≥ III (62.9 %), and recurrent tumors (64.5 %). In the cluster analysis of 231 patients with malignant lesions, two showed lower sensitivity: Cluster 3 (62.4 %), consisting of patients with recurrent tumors and post-BCG treatment, and Cluster 4 (55.7 %), consisting of patients with primary tumors and urine cytology class ≥ III. Clusters 1 and 2, consisting of patients without BCG treatment and patients with lower urine cytology classes, exhibited higher sensitivities (94.4 % and 87.7 %). Among all clusters, Cluster 4 had the highest proportion of specimens which were negative for both PDD and white light (WL) findings but actually had malignant lesions (20.8 %). CONCLUSIONS PDD-assisted TURBT sensitivity was lower in subclasses after BCG treatment or with cytology class III or higher. Random biopsy for PDD/WL double-negative lesions may improve diagnostic accuracy in these subclasses.

Racial Differences in the Detection Rate of Bladder Cancer Using Blue Light Cystoscopy: Insights from a Multicenter Registry. Cancers (Basel) 2024; 16:1268. [PMID: 38610946 PMCID: PMC11011163 DOI: 10.3390/cancers16071268] [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: 03/06/2024] [Revised: 03/16/2024] [Accepted: 03/22/2024] [Indexed: 04/14/2024] Open
Abstract
The use of blue light cystoscopy (BLC) has been shown to improve bladder tumor detection. However, data demonstrating the efficacy of BLC across different races are limited. Herein, we aim to evaluate heterogeneity in the characteristics of BLC for the detection of malignant lesions among various races. Clinicopathologic information was collected from patients enrolled in the multi-institutional Cysview® registry (2014-2021) who underwent transurethral resection or biopsy of bladder tumors. Outcome variables included sensitivity and negative and positive predictive values of BLC and white light cystoscopy (WLC) for the detection of malignant lesions among various races. Overall, 2379 separate lesions/tumors were identified from 1292 patients, of whom 1095 (85%) were Caucasian, 96 (7%) were African American, 51 (4%) were Asian, and 50 (4%) were Hispanic. The sensitivity of BLC was higher than that of WLC in the total cohort, as well as in the Caucasian and Asian subgroups. The addition of BLC to WLC increased the detection rate by 10% for any malignant lesion in the total cohort, with the greatest increase in Asian patients (18%). Additionally, the positive predictive value of BLC was highest in Asian patients (94%), while Hispanic patients had the highest negative predictive value (86%). Our study showed that regardless of race, BLC increases the detection of bladder cancer when combined with WLC.

Diagnostic and therapeutic effects of fluorescence cystoscopy and narrow-band imaging in bladder cancer: a systematic review and network meta-analysis. Int J Surg 2023; 109:3169-3177. [PMID: 37526087 PMCID: PMC10583940 DOI: 10.1097/js9.0000000000000592] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Accepted: 06/26/2023] [Indexed: 08/02/2023]
Abstract
BACKGROUND This review aims to compare the efficacies of fluorescence cystoscopy, narrow-band imaging (NBI), and white light cystoscopy in the treatment and diagnosis of bladder cancer. METHODS The authors searched PubMed, EMbase, Web of Science, and the Cochrane Library from January 1990 to April 2022. A total of 26 randomized controlled studies and 22 prospective single-arm studies were selected. Most patients had nonmuscle-invasive bladder cancer. The study protocol has been registered at PROSPERO. RESULTS In the pairwise meta-analysis, 5-aminolevulinic acid (5-ALA) reduced the short-term and long-term recurrence rates of bladder cancer compared with white light cystoscopy (WLC); however, no statistical difference was observed in intermediate-term recurrence rates (RR=0.79, 95% CI: 0.57-1.09). Hexaminolevulinic acid and NBI reduced short-term, intermediate-term, and long-term recurrence rates. The sensitivity of 5-ALA, hexaminolevulinic acid, NBI, and WLC for bladder cancer were 0.89 (95% CI: 0.81-0.94), 0.96 (95% CI: 0.92-0.98), 0.96 (95% CI: 0.92-0.98), and 0.75 (95% CI: 0.70-0.79), respectively; however, only NBI had the same specificity as WLC (0.74 vs. 0.74). Compared with WLC, 5-ALA improved the detection rate of carcinoma in situ and Ta stage bladder cancer but had no advantage in T1 stage tumors (OR=2.39, 95% CI:0.79-7.19). Hexaminolevulinic acid and NBI improved the detection rates of all nonmuscular-invasive bladder cancers. In the network meta-analysis, there was no significant difference in either recurrence or detection rates between 5-ALA, hexaminolevulinic acid, and NBI. CONCLUSION Fluorescence cystoscopy and NBI are advantageous for treating and diagnosing patients with nonmuscle-invasive bladder cancer.

Is a restaging TURBT necessary in high-risk NMIBC if the initial TURBT was performed with blue light? Urol Oncol 2023; 41:109.e9-109.e14. [PMID: 36435710 DOI: 10.1016/j.urolonc.2022.10.026] [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: 08/19/2022] [Revised: 09/26/2022] [Accepted: 10/30/2022] [Indexed: 11/27/2022]
Abstract
OBJECTIVES To evaluate whether a restaging transurethral resection of bladder tumor (TURBT) is necessary in high-risk nonmuscle invasive bladder cancer (NMIBC) if the initial TURBT was performed using blue light (BL) technology. METHODS AND MATERIALS Using the multi-institutional Cysview registry between 2014 and 2021, all consecutive adult patients with known NMIBC (Ta and T1 disease) who underwent TURBT followed by a restaging TURBT within 8 weeks were reviewed. Patients were stratified according to their initial TURBT, BL vs. white light (WL), and compared to determine rates of residual disease and upstaging. Univariate analysis was performed using Mann-Whitney U and chi-square tests, with P < 0.05 considered significant. RESULTS Overall, 115 patients had TURBT for NMIBC followed by a restaging TURBT within 8 weeks and were included in the analysis. Patients who underwent BL compared to WL for their initial TURBT had higher rates of benign pathology on restaging TURBT, although this was not statistically significant (47% vs. 30%; P = 0.08). Of patients with residual tumors on restaging TURBT, there were no differences in rates of Ta (22% vs. 26.5%; P = 0.62), T1 (22% vs. 26.5%; P = 0.62), or CIS (5.5% vs. 13%; P = 0.49) when the initial TURBT was done using BL compared to WL. Rates of upstaging to muscle invasive disease were also not different when initial TURBT was performed using BL compared to WL (3% vs. 4%; P = 0.78). CONCLUSIONS TURBT using BL does not reduce rates of residual disease or risk of upstaging on restaging TURBT in Ta or T1 disease. Thus, a restaging TURBT is still necessary even if initial TURBT was performed using BL.

Abstract
PURPOSE We systematically reviewed the effectiveness of hexaminolevulinic acid (HAL) after traditional light cystoscopy vs. only white light cystoscopy (WLC) on nonmuscle-invasive bladder cancer (NMIBC) clinical outcomes. METHODS Systematic literature searches of PubMed, Embase, Web of Science, and the Cochrane database and reference lists were performed. A total of 12 randomized controlled trials (RCTs) of HAL fluorescent cystoscopy (FC) and WLC vs. white light cystoscopy alone for the diagnosis of initial or recurrent bladder cancer that reported bladder cancer recurrence, progression, recurrence-free survival (RFS), and other effects were selected for review. RESULTS Our results included 2,775 patients identified for analysis and showed that the HAL group had a lower recurrence rate than the white light cystoscopy group with a statistically significant difference (RR=0.77, 95% CI 0.69-0.85. P < 0.05), and this advantage still existed for patients receiving intravesical chemotherapy. There was also a statistically significant difference in favour of fluorescent cystoscopy in recurrence-free survival and progression rate (HR=0.79, 95% CI 0.67-0.92. P < 0.05, RR = 0.63, 95% CI 0.43-0.94. P < 0.05, respectively). The time to first recurrence was not significantly different from that in the WLC group (SMD=0.73, 95% CI, -0.39-1.85. P = 0.2). And the HAL group did not have a significantly reduced residual tumor rate (RR=0.59, 95% CI 0.23-1.51. P = 0.27). CONCLUSIONS Fluorescent cystoscopy was associated with a reduced risk of bladder cancer recurrence and reduced progression rate; it also has advantages for RFS. However, there was no significant difference in the rate of residual tumor and the time of first recurrence. More studies are needed to better understand the effects of the photosensitizer used on NMIBC patients.

Predicting Recurrence of Non-Muscle-Invasive Bladder Cancer: Current Techniques and Future Trends. Cancers (Basel) 2022; 14:cancers14205019.

Abstract
Bladder cancer (BC) is the 10th most common cancer globally and has a high mortality rate if not detected early and treated promptly. Non-muscle-invasive BC (NMIBC) is a subclassification of BC associated with high rates of recurrence and progression. Current tools for predicting recurrence and progression on NMIBC use scoring systems based on clinical and histopathological markers. These exclude other potentially useful biomarkers which could provide a more accurate personalized risk assessment. Future trends are likely to use artificial intelligence (AI) to enhance the prediction of recurrence in patients with NMIBC and decrease the use of standard clinical protocols such as cystoscopy and cytology. Here, we provide a comprehensive survey of the most recent studies from the last decade (N = 70 studies), focused on the prediction of patient outcomes in NMIBC, particularly recurrence, using biomarkers such as radiomics, histopathology, clinical, and genomics. The value of individual and combined biomarkers is discussed in detail with the goal of identifying future trends that will lead to the personalized management of NMIBC.

Abstract
BACKGROUND Around 7500 people are diagnosed with non-muscle-invasive bladder cancer in the UK annually. Recurrence following transurethral resection of bladder tumour is common, and the intensive monitoring schedule required after initial treatment has associated costs for patients and the NHS. In photodynamic diagnosis, before transurethral resection of bladder tumour, a photosensitiser that is preferentially absorbed by tumour cells is instilled intravesically. Transurethral resection of bladder tumour is then conducted under blue light, causing the photosensitiser to fluoresce. Photodynamic diagnosis-guided transurethral resection of bladder tumour offers better diagnostic accuracy than standard white-light-guided transurethral resection of bladder tumour, potentially reducing the chance of subsequent recurrence. OBJECTIVE The objective was to assess the clinical effectiveness and cost-effectiveness of photodynamic diagnosis-guided transurethral resection of bladder tumour. DESIGN This was a multicentre, pragmatic, open-label, parallel-group, non-masked, superiority randomised controlled trial. Allocation was by remote web-based service, using a 1 : 1 ratio and a minimisation algorithm balanced by centre and sex. SETTING The setting was 22 NHS hospitals. PARTICIPANTS Patients aged ≥ 16 years with a suspected first diagnosis of high-risk non-muscle-invasive bladder cancer, no contraindications to photodynamic diagnosis and written informed consent were eligible. INTERVENTIONS Photodynamic diagnosis-guided transurethral resection of bladder tumour and standard white-light cystoscopy transurethral resection of bladder tumour. MAIN OUTCOME MEASURES The primary clinical outcome measure was the time to recurrence from the date of randomisation to the date of pathologically proven first recurrence (or intercurrent bladder cancer death). The primary health economic outcome was the incremental cost per quality-adjusted life-year gained at 3 years. RESULTS We enrolled 538 participants from 22 UK hospitals between 11 November 2014 and 6 February 2018. Of these, 269 were allocated to photodynamic diagnosis and 269 were allocated to white light. A total of 112 participants were excluded from the analysis because of ineligibility (n = 5), lack of non-muscle-invasive bladder cancer diagnosis following transurethral resection of bladder tumour (n = 89) or early cystectomy (n = 18). In total, 209 photodynamic diagnosis and 217 white-light participants were included in the clinical end-point analysis population. All randomised participants were included in the cost-effectiveness analysis. Over a median follow-up period of 21 months for the photodynamic diagnosis group and 22 months for the white-light group, there were 86 recurrences (3-year recurrence-free survival rate 57.8%, 95% confidence interval 50.7% to 64.2%) in the photodynamic diagnosis group and 84 recurrences (3-year recurrence-free survival rate 61.6%, 95% confidence interval 54.7% to 67.8%) in the white-light group (hazard ratio 0.94, 95% confidence interval 0.69 to 1.28; p = 0.70). Adverse event frequency was low and similar in both groups [12 (5.7%) in the photodynamic diagnosis group vs. 12 (5.5%) in the white-light group]. At 3 years, the total cost was £12,881 for photodynamic diagnosis-guided transurethral resection of bladder tumour and £12,005 for white light. There was no evidence of differences in the use of health services or total cost at 3 years. At 3 years, the quality-adjusted life-years gain was 2.094 in the photodynamic diagnosis transurethral resection of bladder tumour group and 2.087 in the white light group. The probability that photodynamic diagnosis-guided transurethral resection of bladder tumour was cost-effective was never > 30% over the range of society's cost-effectiveness thresholds. LIMITATIONS Fewer patients than anticipated were correctly diagnosed with intermediate- to high-risk non-muscle-invasive bladder cancer before transurethral resection of bladder tumour and the ratio of intermediate- to high-risk non-muscle-invasive bladder cancer was higher than expected, reducing the number of observed recurrences and the statistical power. CONCLUSIONS Photodynamic diagnosis-guided transurethral resection of bladder tumour did not reduce recurrences, nor was it likely to be cost-effective compared with white light at 3 years. Photodynamic diagnosis-guided transurethral resection of bladder tumour is not supported in the management of primary intermediate- to high-risk non-muscle-invasive bladder cancer. FUTURE WORK Further work should include the modelling of appropriate surveillance schedules and exploring predictive and prognostic biomarkers.

Abstract
BACKGROUND: Recurrence of non–muscle-invasive bladder cancer (NMIBC) is common after transurethral resection of bladder tumor (TURBT). Photodynamic diagnosis (PDD) provides better diagnostic accuracy and more complete tumor resection and may reduce recurrence. However, there is limited evidence on the longer-term clinical effectiveness and cost-effectiveness of PDD-guided resection. METHODS: In this pragmatic, open-label, parallel-group randomized trial conducted in 22 U.K. National Health Service hospitals, we recruited participants with a suspected first diagnosis of NMIBC at intermediate or high risk for recurrence on the basis of routine visual assessment before being listed for TURBT. Participants were assigned (1:1) to PDD-guided TURBT or to standard white light (WL)–guided TURBT. The primary clinical outcome was time to recurrence at 3 years of follow-up, analyzed by modified intention to treat. RESULTS: A total of 538 participants were enrolled (269 in each group), and 112 participants without histologic confirmation of NMIBC or who had had cystectomy were excluded. After 44 months’ median follow-up, 86 of 209 in the PDD group and 84 of 217 in the WL group had recurrences. The hazard ratio for recurrence was 0.94 (95% confidence interval [CI], 0.69 to 1.28; P=0.70). Three-year recurrence-free rates were 57.8% (95% CI, 50.7 to 64.2) and 61.6% (95% CI, 54.7 to 67.8) in the PDD and WL groups, respectively, with an absolute difference of −3.8 percentage points (95% CI, −13.37 to 5.59) favoring PDD. Adverse events occurred in less than 2% of participants, and rates were similar in both groups, as was health-related quality of life. PDD-guided TURBT was £876 (95% CI, −766 to 2518; P=0.591) more costly than WL-guided TURBT over a 3-year follow-up, with no evidence of a difference in quality-adjusted life years (−0.007; 95% CI, −0.133 to 0.119; P=0.444). CONCLUSIONS: PDD-guided TURBT did not reduce recurrence rates, nor was it cost-effective compared with WL at 3 years.

Abstract
OBJECTIVES To assess the effects of blue light-enhanced transurethral resection of bladder tumor (TURBT) compared to white light-based TURBT in the treatment of non-muscle invasive bladder cancer (NMIBC). METHODS Based on a published protocol we performed a systematic search of multiple databases from their inception to March 2021. We included randomized controlled trials (RCTs) comparing blue light (BL) TURBT to white light (WL) TURBT. Our meta-analysis is based on a random-effect model. We assessed the quality of evidence on a per-outcome basis according to the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) approach. RESULTS We included 16 randomized controlled trials involving a total of 4325 participants in this review. BL TURBT may reduce the risk of disease recurrence over time (hazard ratio (HR) 0.66, 95% confidence interval (CI) 0.54 to 0.81; low certainty evidence) depending on baseline risk. For participants with low-, intermediate-, and high-risk NMIBC, this corresponded to 48 (66 fewer to 27 fewer), 109 (152 fewer to 59 fewer), and 147 (211 fewer to 76 fewer) fewer recurrences per 1000 participants when compared to WL TURBT, respectively. BL TURBT may also reduce the risk of disease progression over time (HR 0.65, 95% CI 0.50 to 0.84; low-certainty evidence) depending on baseline risk. For participants with low-, intermediate-, and high-risk NMIBC, this corresponded to 1 (1 fewer to 0 fewer), 17 (25 fewer to 8 fewer), and 56 (81 fewer to 25 fewer) fewer progressions per 1000 participants when compared to WL TURBT, respectively. CONCLUSIONS Our findings suggest a favorable impact of BL TURBT on the risk of disease recurrence and progression; however, whether this risk reduction is clinically relevant greatly depends on the baseline risk of patients. We did not find an increase in severe surgical complications with BL cystoscopy, and we did not find any trial evidence on other, non-surgical adverse events.

Abstract
BACKGROUND Disease recurrence and progression remain major challenges in the treatment of non-muscle invasive bladder cancer (NMIBC). Blue light-enhanced transurethral resection of bladder cancer (TURBT) is an approach to improve staging and achieve a complete resection of NMIBC. OBJECTIVES To assess the effects of blue light-enhanced TURBT compared to white light-based TURBT in the treatment of NMIBC. SEARCH METHODS We searched several medical literature databases, including the Cochrane Library, MEDLINE, and Embase, as well as trial registers, including ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform. We performed a comprehensive search with no restrictions on language of publication or publication status until March 2021. SELECTION CRITERIA We included randomized controlled trials using blue light versus white light TURBT. Included participants had a high level of suspicion based on imaging or 'visible diagnosis' for primary urothelial carcinoma of the bladder or recurrent urothelial carcinoma of the bladder upon cytoscopy. We excluded studies in which blue light was used in a surveillance setting. DATA COLLECTION AND ANALYSIS: Two review authors independently performed data extraction and risk of bias assessment. Our primary outcomes were time to disease recurrence, time to disease progression, and serious surgical complications. Secondary outcomes were time to death from bladder cancer, any adverse events, and non-serious complications. We rated the certainty of evidence using the GRADE approach. MAIN RESULTS We included 16 randomized controlled trials involving a total of 4325 participants in the review. The studies compared blue light versus white light TURBT for treatment of NMIBC. Primary outcomes Blue light TURBT may reduce the risk of disease recurrence over time (hazard ratio (HR) 0.66, 95% confidence interval (CI) 0.54 to 0.81; low-certainty evidence) depending on baseline risk. For participants with low-, intermediate-, and high-risk NMIBC, this corresponded to 48 (66 fewer to 27 fewer), 109 (152 fewer to 59 fewer), and 147 (211 fewer to 76 fewer) fewer recurrences per 1000 participants when compared to white light TURBT, respectively. Blue light TURBT may also reduce the risk of disease progression over time (HR 0.65, 95% CI 0.50 to 0.84; low-certainty evidence) depending on baseline risk. For participants with low-, intermediate-, and high-risk NMIBC, this corresponded to 1 (1 fewer to 0 fewer), 17 (25 fewer to 8 fewer), and 56 (81 fewer to 25 fewer) fewer progressions per 1000 participants when compared to white light TURBT, respectively. Blue light TURBT may have little or no effect on serious surgical complications (risk ratio (RR) 0.54, 95% CI 0.14 to 2.14; low-certainty evidence). This corresponded to 10 fewer (19 fewer to 25 more) surgical complications per 1000 participants with blue light TURBT. Secondary outcomes Blue light TURBT may have little or no effect on the risk of death from bladder cancer over time (HR 0.55, 95% CI 0.19 to 1.61; low-certainty evidence). This corresponded to 22 deaths per 1000 participants with white light TURBT and 10 fewer (17 fewer to 13 more) deaths per 1000 participants with blue light TURBT. We are very uncertain how blue light TURBT affects the outcome adverse events of any grade (RR 1.09, 95% CI 0.88 to 1.33; low-certainty evidence). No analysis was possible for the outcome non-serious surgical complications, as it was not reported by any of the included studies. AUTHORS' CONCLUSIONS Blue light-enhanced TURBT for the treatment of non-muscle invasive bladder cancer compared to white light-based TURBT may reduce the risk of disease recurrence and disease progression over time depending on baseline risk. There may be little or no effect on serious surgical complications. The certainty of evidence for our findings was low, meaning that future studies are likely change to the reported estimates of effect. Frequent issues that led to downgrading of the certainty of the evidence were study limitations, inconsistency, and imprecision.

Abstract
OBJECTIVES To evaluate the role of blue-light cystoscopy (BLC) in detecting invasive tumours that were not visible on white-light cystoscopy (WLC). PATIENTS AND METHODS Using the multi-institutional Cysview registry database, patients who had at least one white-light negative (WL-)/blue-light positive (BL+) lesion with invasive pathology (≥T1) as highest stage tumour were identified. All WL-/BL+ lesions and all invasive tumours in the database were used as denominators. Relevant baseline and outcome data were collected. RESULTS Of the 3514 lesions (1257 unique patients), 818 (23.2%) lesions were WL-/BL+, of those, 55 (7%) lesions were invasive (48 T1, seven T2; 47 unique patients) including 28/55 (51%) de novo invasive lesions (26 unique patients). In all, 21/47 (45%) patients had WL-/BL+ concommitant carcinoma in situ and/or another T1 lesions. Of 22 patients with a WL-/BL+ lesion who underwent radical cystectomy (RC), high-risk pathological features leading to RC was only visible on BLC in 18 (82%) patients. At time of RC, 11/22 (50%) patients had pathological upstaging including four (18%) with node-positive disease. CONCLUSIONS A considerable proportion of invasive lesions are only detectable by BLC and the rate of pathological upstaging is significant. Our present findings suggest an additional benefit of BLC in the detection of invasive bladder tumours that has implications for treatment approach.

Abstract
Despite early detection and regular surveillance of non-muscle invasive bladder cancer (NMIBC), recurrence and progression rates remain exceedingly high for this highly prevalent malignancy. Limited visualization of malignant lesions with standard cystoscopy and associated false-negative biopsy rates have been the driving force for investigating alternative and adjunctive technologies for improved cystoscopy. The aim of our systematic review and meta-analysis was to compare the sensitivity, specificity, and oncologic outcomes of photodynamic diagnosis (PDD) fluorescence, narrow band imaging (NBI), and conventional white light cystoscopy (WLC) in detecting NMIBC. Out of 1,087 studies reviewed, 17 prospective non-randomized and randomized controlled trials met inclusion criteria for the study. We demonstrated that tumor resection with either PDD and NBI exhibited lower recurrence rates and greater diagnostic sensitivity compared to WLC alone. NBI demonstrated superior disease sensitivity and specificity as compared to WLC and an overall greater hierarchical summary receiver operative characteristic. Our findings are consistent with emerging guidelines and underscore the value of integrating these enhanced technologies as a part of the standard care for patients with suspected or confirmed NMIBC.

Abstract
Objective: This study aimed to investigate the association between Photodynamic Diagnosis (PDD) with hexaminolevulinate (HAL) and the rate of complete resection and disease persistence at first follow-up cystoscopy for non-muscle-invasive bladder cancer (NMIBC) in UK real-world practice. Methods: Audit data were pooled from six UK centres where HAL PDD was used in patients with a new NMIBC diagnosis undergoing transurethral resection of bladder tumours (TURBT) since 2008. Patients received adjunctive intra-vesical therapy and surveillance in line with European and UK guidelines, including early re-resection in high-grade NMIBC. Results: PDD-assisted TURBT was done in 837 patients with new NMIBC. The detrusor muscle was present in 69.4% of cases. At early re-TURBT in 207 high-risk patients, 13.0% had residual disease. Multifocal disease was the most significant factor in increasing the rate of residual disease (odds ratio excluding cases of CIS=4.1; 95% confidence interval 1.5–11.3). The recurrence rate at first follow-up cystoscopy (RRFFC) was 10.6% (8.9% in patients with complete initial TURBT). In the historical cohort undergoing good-quality white-light TURBT, RRFFC was 31%; 40.5% of high-risk patients had residual disease at early re-TURBT. Conclusion: HAL PDD may increase the rates of complete resection, reducing the risk of early recurrence and the need for routine re-resection in high-grade NMIBC. Level of evidence: 2b.

Abstract
PURPOSE OF REVIEW It has been firmly established that hexaminolevulinate-assisted blue light cystoscopy (HAL-BLC) reduces cancer recurrence rates. This review explores the impact of HAL-BLC on other meaningful outcomes in patients with bladder cancer, including disease progression, and earlier detection of disease at the time of surveillance cystoscopy. RECENT FINDINGS A randomized clinical trial confirmed earlier implementation of HAL-BLC at the time of surveillance cystoscopy increased identification of cancerous lesions, including those of high grade, when compared with white light cystoscopy. In addition, the evidence is evolving that the use of HAL-BLC at the time of endoscopic treatment of high-risk tumors may lead to lower rates of progression to muscle invasion, and this in part may be due to better risk stratification leading to changes in treatment plan. The clinical contexts for the use of HAL-BLC are broader than prior knowledge. It is also becoming more clear that the positive impact of HAL-BLC is likely more than just reducing cancer recurrence rates, and patients would benefit from the technology at many time points in the management and follow-up of their disease.

Abstract
PURPOSE OF REVIEW Bladder-sparing trimodality therapy (TMT) has become an accepted alternative to cystectomy for selected muscle invasive bladder cancer (MIBC) patients unfit for cystectomy or opting for bladder preservation. This review will summarize recent advances in TMT for MIBC. RECENT FINDINGS A growing body of literature has emerged which supports the use of TMT. However, its delivery is yet to be standardized. The role of chemotherapy and predictive biomarkers remain to be elucidated. Novel bladder-sparing approaches, drug combinations including immunotherapy and targeted therapies are under investigation in clinical trials, with the goal of ultimately enhancing survival and quality of life outcomes. Recent advances in TMT have made bladder preservation possible for MIBC patients seeking an alternative local therapy to cystectomy. With careful patient selection, TMT offers comparable survival outcomes to cystectomy, and improved quality of life as patients are able to successfully retain their bladder.

[PMID: 31956355 PMCID: PMC6959070 DOI: 10.7150/jca.34527] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2019] [Accepted: 09/27/2019] [Indexed: 11/05/2022] Open
Abstract
Objective: To assess the diagnostic test accuracy (DTA) of photodynamic diagnosis with 5-aminolaevulinic acid (5-ALA), hexylaminolevulinate (HAL) and narrow band imaging (NBI) for non-muscle-invasive bladder cancer (NMIBC), with white light-guided cystoscopy (WLC) as reference standard. Materials and Methods: A systematic review and narrative synthesis was performed in accordance with PRISMA. Major electronic databases were searched until 20th May 2019. All studies assessing the DTA of 5-ALA, HAL and NBI compared with WLC at patient and lesion-level were included. Relevant sensitivity analyses and risk of bias (RoB) assessment were undertaken. Results: 26 studies recruiting 3979 patients were eligible for inclusion. For patient-level analysis, NBI appeared to be the best (median sensitivity (SSY) 100%, median specificity (SPY) 68.45%, median positive predictive value (PPV) 90.75%, median negative predictive value (NPV) 100% and median false positive rate (FPR) 31.55%), showing better DTA outcomes than either HAL or 5-ALA. For lesion-level analysis, median SSY across NBI, HAL and 5-ALA were 93.08% (IQR 87.04-98.81%), 93.16% (IQR 91.48-97.04%) and 94.42% (IQR 82.37-95.73%) respectively. As for FPR, median values for NBI, HAL and 5-ALA were 20.40% (IQR 13.68-27.36%), 17.43% (IQR 12.79-22.40%) and 28.12% (IQR 22.08-42.39%), respectively. Sensitivity analyses based on studies with low to moderate RoB and studies with n>100 patients show similar findings. Conclusions: NBI appears to outperform 5-ALA and HAL in terms of diagnostic accuracy. All three modalities present high FPR, hence indicating the ability to detect additional cases and lesions beyond WLC.

Abstract
OBJECTIVE To explore the diagnostic performance of image technique based transurethral resection for bladder cancer, with white light-guided cystoscopy (WLC) as the reference standard. DESIGN Systematic review and meta-analysis. DATA SOURCES PubMed/MEDLINE, Web of Science, the Cochrane Library, Central Register of Controlled Trials and Embase from inception to 31 March 2018. METHODS Included studies reported the diagnostic performance of photodynamic diagnosis (PDD) with 5-aminolevulinic acid (5-ALA), PDD with hexaminolevulinic acid (HAL) or narrow band imaging (NBI), with WLC as the reference standard at the patient or lesion level. The studies' risk of bias (RoB) was assessed using Quality Assessment of Diagnostic Studies-2. Data were pooled using a random effect diagnostic meta-analysis, and subgroup analyses were performed. RESULTS Twenty-six studies comprising a total of 3979 patients were included in this diagnostic meta-analysis. Pooled sensitivity (SSY), specificity (SPY), diagnostic OR (DOR) and area under the receiver operating characteristic curve (AUROC) values were calculated per group for NBI, HAL and 5-ALA at the lesion or patient level. NBI showed significant diagnostic superiority compared with WLC at the lesion level (SSY 0.94, 95% CI 0.82 to 0.98; SPY 0.79, 95% CI 0.73 to 0.85; DOR 40.09, 95% CI 20.08 to 80.01; AUROC 0.88, 95% CI 0.85 to 0.91). NBI presented the highest DOR (358.71, 95% CI 44.50 to 2891.71) in the patient level. Subgroup analyses were performed on studies with low to moderate RoB and at least 100 patients at the lesion level. These results were consistent with those of the overall analysis. CONCLUSIONS Pooled data indicated that image technique based transurethral resection (NBI, HAL and 5-ALA) showed diagnostic superiority compared with WLC. Moreover, NBI is potentially the most promising diagnostic intervention, showing the best diagnostic performance outcomes. Further prognostic outcomes of novel imaging technologies compared with those WLC should be explored in addition to current diagnostic performance analysis.

Abstract
White light cystoscopy (WL) is the gold standard for the detection of bladder cancer. It can be performed using a rigid or flexible urethrocystoscope. With the more recent introduction of high definition (HD) techniques, WL cystoscopy has been decisively improved. Supplementary optical techniques are also used to improve the detection of bladder cancer. Among these are photodynamic diagnosis (PDD), narrow-band imaging (NBI), S‑technologies of IMAGE1 S, optical coherence tomography (OCT), confocal laser endomicroscopy (CLE), and Raman spectroscopy. The aim of the present work is to introduce the techniques and to discuss their current role and future potential in the detection of bladder cancer.

Abstract
Bladder cancer (BC) is a complex disease and could be classified into nonmuscle‐invasive BC (NMIBC) or muscle‐invasive BC (MIBC) subtypes according to the distinct genetic background and clinical prognosis. Until now, the golden standard and confirmed diagnosis of BC is cystoscopy and the major problems of BC are the high rate of recurrence and high costs in the clinic. Recent molecular and genetic studies have provided perspectives on the novel biomarkers and potential therapeutic targets of BC. In this article, we provided an overview of the traditional diagnostic approaches of BC, and introduced some new imaging, endoscopic, and immunological diagnostic technology in the accurate diagnosis of BC. Meanwhile, the minimally invasive precision treatment technique, immunotherapy, chemotherapy, gene therapy, and targeted therapy of BC were also included. Here, we will overview the diagnosis and therapy methods of BC used in clinical practice, focusing on their specificity, efficiency, and safety. On the basis of the discussion of the benefits of precision medicine in BC, we will also discuss the challenges and limitations facing the non‐invasive methods of diagnosis and precision therapy of BC. The molecularly targeted and immunotherapeutic approaches, and gene therapy methods to BC treatment improved the prognosis and overall survival of BC patients.

'Real-life experience': recurrence rate at 3 years with Hexvix ® photodynamic diagnosis-assisted TURBT compared with good quality white light TURBT in new NMIBC-a prospective controlled study. World J Urol 2017; 35:1871-1877. [PMID: 28803385 PMCID: PMC5693980 DOI: 10.1007/s00345-017-2077-6] [Citation(s) in RCA: 34] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2017] [Accepted: 07/31/2017] [Indexed: 11/24/2022] Open
Abstract
Purpose To compare the recurrence rate at 3 years (RR-3y) for non-muscle invasive bladder cancer (NMIBC) between good quality (GQ) PDD-TURBT and GQWL-TURBT where PDD is used in routine practice for all new tumours. Methods All new, consecutive, NMIBC that received “good quality” criteria first TURBT across a university hospital service were prospectively recruited to this study over a 4-year period. Data were prospectively collected on all WL-TURBTs performed in 2007/8 and compared with PDD-TURBT from 2009/10. Only resection meeting strict “good quality criteria” were included from each cohort to control for resection quality, then cases were further matched 1:1 based on demographic and pathological criteria. The primary outcome was overall and risk group-specific recurrence rate at 3 years. Results Of 808 patients recruited, 345 had GQ-TURBT for NMIBC and were included. RR-3y was significantly less for GQ-PDD overall [RR-3y: GQ-PDD: 57/146 (39.0%), GQ-WL: 72/135 (53.3%) OR = 0.56 (0.35–0.90) p = 0.02] and on a 1:1 matched pair basis [RR GQ-PDD: 29/118 (24.6) vs. 59/118 (50.0) OR 0.33 (0.19–0.57) p < 0.001)]. Benefit was most marked in high-risk patients: RR-3y in high-risk patients treated with GQ-PDD was 25/48 (52.1%) vs. 28/35 (80%) for GQ-WL [OR 0.27 (0.10–0.74) p = 0.01]. Conclusion When adopted for all new bladder tumour resections in routine practice, PDD appears to be associated with significantly reduced recurrence rates at 3 years in our “real life” experience, particularly in high-risk patients.

Abstract
INTRODUCTION Previous studies have suggested cost-savings using blue light cystoscopy (BLC) with hexaminolevulinate (HAL) compared to white light cystoscopy (WLC) during transurethral resection of bladder tumour (TURBT) for non-muscle-invasive bladder cancer (NMIBC), secondary to improvements in recurrence and progression rates; however, these studies have used 'best case scenario' recurrence rate probabilities, thus decreasing generalizability of the findings. The objective of this study was to perform a contemporary cost-effectiveness assessment of BLC compared to WLC at the time of TURBT. METHODS A decision and cost-effectiveness model with a five-year time horizon following initial TURBT was used. The model was created from the healthcare payer perspective. Comprehensive literature review was performed to obtain contemporary recurrence and progression rates. These values were meta-analyzed for inclusion into the model. Cost variables included in the model were from three large Canadian bladder cancer centres. Model outputs were number of recurrences prevented, bed days saved, and overall costs. One-way sensitivity and scenario analyses were performed to assess model robustness. RESULTS The five-year amortized cost of using BLC with HAL on all incident NMIBC compared to WLC assistance was $4 832,908 for Ontario (n=4696; $1372/patient); $1 168 968 for British Columbia (n=1204; $1295/patient); and $2 484, 872 (n=2680; $1236/patient) for Quebec. Use of BLC with HAL would result in 87 338 fewer recurrences annually. On sensitivity/scenario analyses for Ontario data, if BLC with HAL equipment were provided to the province at no cost, five-year costs would be $4 158 814 and $1181 cost per patient. If BLC with HAL were only used for cystoscopically appearing aggressive tumours, the five-year amortized cost would be $3 874 098, with a cost per patient of $1222. If there was a 20% or 50% improvement in progression rates with BLC plus HAL, the five-year amortized cost would be $2 660 529 and -$598 039 (cost-saving), respectively. CONCLUSIONS TURBT using BLC with HAL for patients with NMIBC is associated with a five-year cost of approximately $1-5 million for jurisdictions of 4-13 million people. Although this translates to a cost of $1200-1400 per patient for their initial TURBT, BLC with HAL improves patients care, reduces recurrences, and decreases the need for hospital beds after TURBT. If this diagnostic procedure eventually improves progression rates, there would be considerably improved cost-effectiveness.

Abstract
Photodynamic diagnostic technique with blue light cystoscopy (BLC) takes advantage of the preferential uptake and accumulation of protoporphyrins in neoplastic tissue which emit a red fluorescence when illuminated with blue light (360-450 nm wavelengths). This allows enhanced visualization of small papillary tumors and flat carcinoma in situ lesions that might have been missed on white light cystoscopy (WLC). There is compelling evidence that the ability of BLC to detect these additional tumors translates into improved recurrence rates compared to WLC. However, the impact of BLC with regard to progression rates and in patients who are managed with intravesical therapy is not yet known. Further work is required to optimize the integration of BLC into clinical practice, but the future for BLC appears promising.

Optimised photodynamic diagnosis for transurethral resection of the bladder (TURB) in German clinical practice: results of the noninterventional study OPTIC III. World J Urol 2016; 35:737-744.

Abstract
Purpose White light cystoscopy (WLC) is the standard procedure for visualising non-muscle invasive bladder cancer (NMIBC). However, WLC can fail to detect all cancerous lesions, and outcomes with transurethral resection of the bladder differ between institutions, controlled trials, and possibly between trials and routine application. This noninterventional study assessed the benefit of hexaminolevulinate blue light cystoscopy (HALC; Hexvix®, Ipsen Pharma GmbH, Germany) plus WLC versus WLC alone in routine use. Methods From May 2013 to April 2014, 403 patients with suspected NMIBC were screened from 30 German centres to perform an unprecedented detailed assessment of the additional detection of cancer lesions with HALC versus WLC alone. Results Among the histological results for 929 biopsy samples, 94.3 % were obtained from suspected cancerous lesions under either WLC or HALC: 59.5 % were carcinoma tissue and 40.5 % were non-cancerous tissue. Of all cancer lesions, 62.2 % were staged as Ta, 20.1 % as T1, 9.3 % as T2, 7.3 % as carcinoma in situ (CIS), and 1.2 % were unknown. Additional cancer lesions (+6.8 %) and CIS lesions (+25 %, p < 0.0001) were detected by HALC plus WLC versus WLC alone. In 10.0 % of patients, ≥1 additional positive lesion was detected with HALC, and 2.2 % of NMIBC patients would have been missed with WLC alone. No adverse events were observed. Conclusions The results of this study demonstrate that HALC significantly improves the detection of NMIBC versus WLC alone in routine clinical practice in Germany. While this benefit is statistically significant across all types of NMIBC, it seems most relevant in CIS.
