Photodynamic Therapeutic Effect during 5-Aminolevulinic Acid-Mediated Photodynamic Diagnosis-Assisted Transurethral Resection of Bladder Tumors. Adv Urol 2024; 2024:7548001. [PMID: 39104915 PMCID: PMC11300098 DOI: 10.1155/2024/7548001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2024] [Accepted: 07/11/2024] [Indexed: 08/07/2024] Open
Abstract
Background Photodynamic diagnosis-assisted transurethral resection of bladder tumors (PDD-TURBT) enhances detection of elusive lesions compared to standard white light-transurethral resection of bladder tumors (WL-TURBT). If minimal light exposure during PDD-TURBT induces the accumulation of reactive oxygen species (ROS), potentially resulting in phototoxicity in small lesions, apoptosis may be triggered in residual small tumors, allowing them to escape resection. We investigated the hypothesis of a potential photodynamic therapeutic effect during PDD-TURBT. Methods and Materials Our study, conducted between January 2016 and December 2020 at Nara Medical University Hospital, focused on a specific emphasis on ROS production. Immunohistochemical analysis for thymidine glycol and N ε -hexanoyl-lysine was performed on 69 patients who underwent 5-aminolevulinic acid-mediated PDD-TURBT and 28 patients who underwent WL-TURBT. Additionally, we incrementally applied the minimal irradiation energy to T24 and UM-UC-3 cells treated with 5-aminolevulinic acid using instruments similar to those used in PDD-TURBT and evaluated intracellular ROS production and phototoxicity. Results Immunohistochemical analysis revealed a significant increase in production of thymidine glycol and N ε -hexanoyl-lysine within the PDD-TURBT group. In T24 and UM-UC-3 cells treated with 5-aminolevulinic acid and light exposure, immunofluorescent staining demonstrated a dose-dependent increase in intracellular ROS production. In addition, higher irradiation energy levels were associated with a greater increase in ROS production and phototoxicity, as well as more significant decrease in mitochondrial membrane potential. Conclusion Although the irradiation energy used in PDD-TURBT did not reach the levels commonly used in photodynamic therapy, our findings support the presence of a potential cytotoxic effect on bladder lesions during PDD-TURBT.

Abstract
OBJECTIVES Bladder cancer, especially non-muscle invasive bladder cancer (NMIBC), is one of the most costly cancers owing to its long-term management. Photodynamic diagnosis-assisted transurethral resection of bladder tumor (PDD-TURBT) reduces the risk of intravesical recurrence. However, its impact on healthcare economics in Japan remains unclear. We evaluated the comprehensive medical costs of Japanese healthcare economics regarding PDD-TURBT. METHODS This large-scale, multicenter, retrospective study included a dataset of 1531 patients who were diagnosed with primary NMIBC who underwent initial TURBT between April 2006 and June 2021. A one-to-one propensity-score matching analysis was used for an unbiased comparison based on postTURBT follow-up periods. The total medical costs, including hospitalization, surgical procedures for TURBT and salvage radical cystectomy, adjuvant intravesical therapies, and follow-up examinations, were compared between white light (WL)-TURBT and PDD-TURBT groups. RESULTS After propensity-score matching, 468 patients each of WL- and PDD-TURBT groups were matched. Total costs were 510 337 128 and 514 659 328 ¥ in WL- and PDD-TURBT groups, respectively. The costs of adjuvant intravesical therapies, follow-up examinations, and salvage radical cystectomy in PDD-TURBT group were equivalent to or lower than those in WL-TURBT group. Furthermore, total costs of high- and highest-risk NMIBC in PDD-TURBT group were either equivalent or lower compared to those in WL-TURBT group. CONCLUSIONS The total costs associated with PDD-TURBT were higher compared to WL-TURBT, while there is the potential of PDD-TURBT to reduce the burden on healthcare economics in limited cases.

Real-world experience with 5-aminolevulinic acid for photodynamic diagnosis of bladder cancer (3rd report): Cost impact of transurethral resection of bladder tumor in Japan. Photodiagnosis Photodyn Ther 2023; 44:103758. [PMID: 37604217 DOI: 10.1016/j.pdpdt.2023.103758] [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: 06/29/2023] [Revised: 08/02/2023] [Accepted: 08/18/2023] [Indexed: 08/23/2023]
Abstract
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.

Abstract
BACKGROUND AND OBJECTIVE Bladder cancer is common among current and former smokers. High bladder cancer mortality may be decreased through early diagnosis and screening. The aim of this study was to appraise decision models used for the economic evaluation of bladder cancer screening and diagnosis, and to summarise the main outcomes of these models. METHODS MEDLINE via PubMed, Embase, EconLit and Web of Science databases was systematically searched from January 2006 to May 2022 for modelling studies that assessed the cost effectiveness of bladder cancer screening and diagnostic interventions. Articles were appraised according to Patient, Intervention, Comparator and Outcome (PICO) characteristics, modelling methods, model structures and data sources. The quality of the studies was also appraised using the Philips checklist by two independent reviewers. RESULTS Searches identified 3082 potentially relevant studies, which resulted in 18 articles that met our inclusion criteria. Four of these articles were on bladder cancer screening, and the remaining 14 were diagnostic or surveillance interventions. Two of the four screening models were individual-level simulations. All screening models (n = 4, with three on a high-risk population and one on a general population) concluded that screening is either cost saving or cost effective with cost-effectiveness ratios lower than $53,000/life-years saved. Disease prevalence was a strong determinant of cost effectiveness. Diagnostic models (n = 14) assessed multiple interventions; white light cystoscopy was the most common intervention and was considered cost effective in all studies (n = 4). Screening models relied largely on published evidence generalised from other countries and did not report the validation of their predictions to external data. Almost all diagnostic models (n = 13 out of 14) had a time horizon of 5 years or less and most of the models (n = 11) did not incorporate health-related utilities. In both screening and diagnostic models, epidemiological inputs were based on expert elicitation, assumptions or international evidence of uncertain generalisability. In modelling disease, seven models did not use a standard classification system to define cancer states, others used risk-based, numerical or a Tumour, Node, Metastasis classification. Despite including certain components of disease onset or progression, no models included a complete and coherent model of the natural history of bladder cancer (i.e. simulating the progression of asymptomatic primary bladder cancer from cancer onset, i.e. in the absence of treatment). CONCLUSIONS The variation in natural history model structures and the lack of data for model parameterisation suggest that research in bladder cancer early detection and screening is at an early stage of development. Appropriate characterisation and analysis of uncertainty in bladder cancer models should be considered a priority.

Abstract
BACKGROUND Photodynamic diagnosis-assisted transurethral resection of bladder tumor reduces the risk of intravesical recurrence compared with conventional white light-transurethral resection of bladder tumor. However, the patient burden of costs for photodynamic diagnosis-transurethral resection of bladder tumor is higher than that for white light-transurethral resection of bladder tumor per installment, and the impact of the medical economics of photodynamic diagnosis-transurethral resection of bladder tumor is unclear. Therefore, we evaluated the Japanese health care system-based cost-effectiveness of photodynamic diagnosis-transurethral resection of bladder tumor compared with that of white light-transurethral resection of bladder tumor. METHODS We conducted a retrospective chart review of 100 patients who underwent initial white light- or photodynamic diagnosis-transurethral resection of bladder tumor for non-muscle invasive bladder cancer from February 2012 to August 2019. Cumulative intravesical recurrences during 1000 post-operative days after the initial transurethral resection of bladder tumor were counted. Furthermore, the cumulative costs were calculated using the Diagnostic Procedure Combination and Per-Diem Payment System unique to Japan. The costs/year/person calculated using the person-year method was compared between the white light- and photodynamic diagnosis-transurethral resection of bladder tumor. RESULTS Among the 100 patients, 40 (40%) and 60 (60%) underwent the initial white light- and photodynamic diagnosis-transurethral resection of bladder tumor, respectively. The cumulative incidence of bladder recurrence requiring hospitalization and transurethral resection of bladder tumor was 20 and 5% for the white light-transurethral resection of bladder tumor and photodynamic diagnosis-transurethral resection of bladder tumor, respectively. The costs for hospitalization and surgical procedures per white light- or photodynamic diagnosis-transurethral resection of bladder tumor were 348 228 and 481 820 Japanese yen, respectively. The cost/year/person by the person-year method was 8073 and 8557 Japanese yen for the white light- and photodynamic diagnosis-transurethral resection of bladder tumor, respectively. CONCLUSIONS The cost/year/person for hospitalization and surgical procedures was slightly different between the white light- and photodynamic diagnosis-transurethral resection of bladder tumor. Furthermore, photodynamic diagnosis-transurethral resection of bladder tumor can reduce intravesical recurrence and is more cost-effective than white light-transurethral resection of bladder tumor.

Urol Oncol 2022; 41:207.e9-207.e16. [PMID: 36564259 DOI: 10.1016/j.urolonc.2022.11.014] [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: 05/14/2022] [Revised: 11/03/2022] [Accepted: 11/21/2022] [Indexed: 12/24/2022]
Abstract
INTRODUCTION AND OBJECTIVE Management of non-muscle-invasive bladder cancer (NMIBC) significantly impacts healthcare resource utilization due to requirements for ongoing surveillance. White light cystoscopy (WLC) represents the traditional approach to NMIBC disease surveillance, though physicians utilizing WLC alone may fail to detect all cancerous lesions. The approval of blue light cystoscopy (BLC) as an adjunct to WLC enhances the urologist's ability to more readily detect cancerous tissue. A more complete resection will reduce recurrences and could result in reduced costs for the US healthcare system. This analysis quantifies the clinical and economic impact of the incorporation of BLC in the management of NMIBC in ambulatory surgical centers (ASCs) considering current Center for Medicare Services (CMS) patient-physician coverage and reimbursement. METHODS AND MATERIALS A budget impact model was developed to assess projected ASC costs for a cohort of 50 newly diagnosed bladder cancer patients over a 2-year follow-up comparing WLC alone vs. WLC + BLC. Treatment and surveillance intervals were based on AUA/SUO clinical guidelines. Clinical and cost metrics for staging and biopsy rates were assessed, with cost inputs based on Medicare reimbursement rates. RESULTS Use of WLC + BLC for NMIBC surveillance resulted in the identification of 5 additional NMIBC recurrences compared to WLC alone. There was an associated increased cost of performing BLC in an ASC setting, with a net increase in the total cost of care for NMIBC of $110 per cystoscopy over a 2-year period. If recurrences missed using WLC alone were to progress prior to detection, the model projects an increase in treatment costs borne by Medicare of $9,097 to $34,538 due to more intensive treatments required for the increased risk of recurrence. CONCLUSIONS Modeled results suggests that the Medicare program will incur increased costs, due to the gap between added costs per cystoscopy due to BLC. The current discrepancy in reimbursement disincentivizes community-based ASCs from adopting BLC, resulting in suboptimal patient care while increasing downstream treatment costs to Medicare, necessitated when missed disease progresses to higher stage/grade disease. The findings have important clinical implications for the optimal management of NMIBC and should inform healthcare policies that promote cost-effectiveness and enhanced patient outcomes.

Abstract
OBJECTIVE To assess whether single immediate intravesical chemotherapy (SIIC) adds value to bladder tumour management in combination with novel optical techniques: enhanced transurethral resection of bladder tumour (TURBT). METHODS A systematic search was performed using the PubMed and Web of Science databases in September 2020 according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) extension statement for network meta-analyses. Studies that compared recurrence rates among intervention groups (TURBT with photodynamic diagnosis [PDD] ± SIIC, narrow-band imaging [NBI] ± SIIC, or white-light cystoscopy [WLC] + SIIC) and a control group (TURBT with WLC alone) were included. We used the Bayesian approach in the network meta-analysis. RESULTS Twenty-two studies (n = 4519) met our eligibility criteria. Out of six different interventions including three different optical techniques, compared to WLC alone, blue-light cystoscopy (BLC) plus SIIC (odds ratio [OR] 0.349, 95% credible interval [CrI] 0.196-0.601) and BLC alone (OR 0.668, 95% CrI 0.459-0.931) were associated with a significantly lower likelihood of 12-month recurrence rate. In the sensitivity analysis, out of eight different interventions compared to WLC alone, PDD by 5-aminolevulinic acid plus SIIC (OR 0.327, 95% CrI 0.159-0.646) and by hexaminolevulinic acid plus SIIC (OR 0.376, 95% CrI 0.172-0.783) were both associated with a significantly lower likelihood of 12-month recurrence rate. NBI with and without SIIC was not associated with a significantly lower likelihood of 12-month recurrence rate (OR 0.385, 95% CrI 0.105-1.29 and OR 0.653, 95% CrI 0.343-1.15). CONCLUSION Blue-light cystoscopy during TURBT with concomitant SIIC seems to yield superior recurrence outcomes in patients with non-muscle-invasive bladder cancer. The use of PDD was able to reduce the 12-month recurrence rate; moreover, concomitant SIIC increased this risk benefit by a 32% additional reduction in odds ratio. Although using PDD could reduce the recurrence rate, SIIC remains necessary. Moreover, ranking analysis showed that both PDD and NBI, plus SIIC, were better than these techniques alone.

Abstract
OBJECTIVE To determine the estimated budget impact to practices that incorporate blue light cystoscopy (BLC) with hexaminolevulinate HCl (HAL) for the surveillance of non-muscle-invasive bladder cancer (NMIBC) in the clinic setting. With the introduction of advanced technologies in the clinic setting such as HAL, further cost comparative research is needed to justify HAL as a high value option. MATERIAL AND METHODS A budget impact model was developed from the facility perspective assessing projected costs at 2 years for a simulated facility with 50 newly diagnosed bladder cancer patients. Treatment and surveillance cystoscopy intervals were based on clinical guidelines. Clinical inputs, including tumor stage and grade at diagnosis, rates of recurrence and relative risk reduction when using BLC with HAL, were derived from published studies. Cost inputs were based on Medicare reimbursement rates and facility costs. RESULTS Use of BLC identified 9 additional recurrences over two years compared to white light cystoscopy alone. Use of flexible BLC for surveillance marginally increased costs to the practice, with a net difference of $0.76 per cystoscopy over 2 years. CONCLUSIONS From the office/clinic perspective, the model suggests that the use of flexible BLC for the surveillance of NMIBC may not impact cost per cystoscopy and identifies 9 recurrences over 2 years that would be missed using white light cystoscopy alone. These findings could have important implications in the management of NIMBC and help guide clinical practice guidelines that promote cost-effective care and improved patient outcomes.

Abstract
PURPOSE Non-muscle invasive bladder cancer (NMIBC) is a malignancy restricted to the inner lining of the bladder. Intravesical Bacillus Calmette-Guerin (BCG) following transurethral resection of the bladder tumor is the mainstay first-line treatment for high-risk NMIBC patients. Two systematic literature reviews (SLRs) were conducted to further assess the current evidence on BCG use in NMIBC and the humanistic and economic burden of disease. METHODS Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, Embase® and MEDLINE® were searched using the Ovid platform to identify interventional or real-world evidence studies on the health-related quality of life (HRQoL) and economic burden in NMIBC. Limited evidence was found from initial economic SLR searches in NMIBC, so additional targeted searches for bladder cancer were conducted to expand findings. RESULTS Fifty-nine publications were included in the HRQoL SLR, of which 23 reported HRQoL and symptoms in NMIBC. At diagnosis, HRQoL was comparable with population norms but worsened considerably 2 years following diagnosis. Maintenance therapy with intravesical BCG was associated with reduced HRQoL, and treatment-related adverse events (AEs) resembled typical NMIBC symptoms. Twenty-two studies reported decreasing BCG compliance over time. Common AEs with BCG were frequent urination, lower urinary tract symptoms, pain, and hematuria. Forty-two publications were included in the economic SLR, of which nine assessed healthcare costs and resource use in NMIBC or bladder cancer. High-risk disease and high-intensity treatment were associated with increased healthcare costs. CONCLUSION NMIBC has a considerable symptomatic, HRQoL, and economic burden. Symptoms persisted and HRQoL worsened despite intravesical BCG treatment. NMIBC is a costly disease, with higher healthcare costs associated with increased risk of disease progression and recurrence. There is a high unmet need for safe and effective treatments that reduce the risk of disease progression and recurrence, provide symptomatic relief, and improve HRQoL for patients.

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.

Abstract
The management of non-muscle-invasive bladder cancer (NMIBC) has evolved from the first reports on bladder endoscopy and transurethral resection to the introduction of adjuvant intravesical treatment. However, disease recurrence and progression remain an ongoing risk, placing a heavy burden on healthcare resources and on patients' quality of life. Deeper understanding of the molecular basis of the disease and developments in optics, lasers and computer science are already offering opportunities to revolutionize care and improve long-term prognosis. This article discusses developments likely to cause a paradigm shift towards the delivery of personalized care and reduced burden of disease in NMIBC.
