Comparative assessment of disease recurrence after transurethral resection of non-muscle-invasive bladder cancer with and without a photodynamic diagnosis using 5-aminolevulinic acid: a propensity score-matching analysis. Int J Clin Oncol 2024; 29:205-212. [PMID: 38112832 DOI: 10.1007/s10147-023-02447-2] [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: 09/13/2023] [Accepted: 11/24/2023] [Indexed: 12/21/2023]
Abstract
BACKGROUND Among patients with non-muscle-invasive bladder cancer (NMIBC), systematic reviews showed lower recurrence rate in patients treated with photodynamic diagnosis (PDD)-assisted transurethral resection of bladder tumor (TURBT) than with white-light (WL) TURBT. However, the result is not consistent between clinical trials and the significance of preoperatively available factors in disease recurrence after PDD-TURBT remains unclear. METHODS The present study retrospectively analyzed 1174 NMIBC patients who underwent TURBT and were followed up for ≥ 6 months. Among 1174 patients, 385 and 789 underwent PDD-TURBT with oral 5-aminolevulinic acid (the PDD group) and WL-TURBT (the WL group), respectively. Recurrence-free survival (RFS) was compared between the PDD and WL groups before and after propensity score matching, and the impact of several baseline parameters on RFS between the 2 groups was investigated after matching. RESULTS Before propensity score matching, RFS was significantly longer in the PDD group than in the WL group (P = 0.006). After matching, 383 patients were included in both groups, and RFS was significantly longer in the PDD group than in the WL group (P < 0.001). In the cohort after matching, RFS between the two groups was compared in each subgroup classified according to baseline parameters, including age, sex, history of previous or concomitant upper urinary tract urothelial carcinoma, preoperative urinary cytology, tumor multiplicity, and tumor size, and significantly longer RFS was observed in the PDD group in all subgroups, except for the patients with tumors ≥ 30 mm (P = 0.21). CONCLUSION These results suggest that PDD-TURBT prolongs RFS in NMIBC patients, except for those with tumors ≥ 30 mm.

Abstract
Bladder cancer is one of the most financially burdensome cancers globally, from its diagnostic to its terminal stages. The impact it imposes on patients and the medical community is substantial, exacerbated by the absence of disease-specific characteristics and limited disease-free spans. Frequent recurrences, impacting nearly half of the diagnosed population, require frequent and invasive monitoring. Given the advancing comprehension of its etiology and attributes, bladder cancer is an appealing candidate for screening strategies. Cystoscopy is the current gold standard for bladder cancer detection, but it is invasive and has the potential for undesired complications and elevated costs. Although urine cytology is a supplementary tool in select instances, its efficacy is limited due to its restricted sensitivity, mainly when targeting low-grade tumors. Although most of these assays exhibit higher sensitivity than urine cytology, clinical guidelines do not currently incorporate them. Consequently, it is necessary to explore novel screening assays to identify distinctive alterations exclusive to bladder cancer. Thus, integrating potential molecular assays requires further investigation through more extensive validation studies. Within this article, we offer a comprehensive overview of the critical features of bladder cancer while conducting a thorough analysis of the FDA-approved assays designed to diagnose and monitor its recurrences.

Abstract
Bladder cancer remains one of the costliest malignancies to manage. We provide a narrative review of literature assessing the economic burden and cost-effectiveness of bladder cancer treatment and surveillance. This is an update to a previous review and focuses on data published within the past 10 years. We queried PubMed and MEDLINE for all bladder cancer cost-related literature between 2013 and 2023. After initial screening, 117 abstracts were identified, 50 of which were selected for inclusion in our review. Management of disease recurrence and treatment complications contributes significantly to the high cost of care. High-value interventions are therefore treatments that improve recurrence-free and overall survival at minimal additional toxicity. De-escalation of surveillance and diagnostic interventions may help to reduce costs in this space without compromising oncologic control. The persistently rising cost of novel cancer drugs undermines their value when only modest gains in efficacy are observed. Multiple cost-effectiveness analyses have been published and are useful for contextualizing the cost, efficacy, and impact on quality of life that interventions have in this population. Further cost-effectiveness work is needed to better characterize the impact that treatment costs have on patients' financial well-being and quality of life.

Healthcare Resource Utilization and Cost Burden of BCG-Treated Non-Muscle Invasive Bladder Cancer Patients in Germany: A Retrospective Claims Analysis. CLINICOECONOMICS AND OUTCOMES RESEARCH 2023; 15:227-237. [PMID: 37035831 PMCID: PMC10075214 DOI: 10.2147/ceor.s398180] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Accepted: 03/18/2023] [Indexed: 04/03/2023] Open
Abstract
Background Intermediate and high-risk non-muscle-invasive bladder cancer (NMIBC) is typically managed with transurethral resection of the bladder tumour (TURBT) followed by intravesical Bacillus Calmette-Guérin (BCG) immunotherapy; however, NMIBC patients can become refractory or unresponsive to BCG treatment, and/or progress to muscle-invasive bladder cancer (MIBC). Healthcare resource utilization (HCRU) and costs in these patient populations are high. Methods A retrospective longitudinal cohort design of adult (≥18 years) patients with bladder cancer and BCG treatment (01/01/2012-31/12/2017) was conducted using data from a representative subset of the German statutory health insurance database. During the follow-up period after last BCG, patients were categorized into subgroups of No further NMIBC treatment, Continuous treatment for NMIBC, or MIBC evidence; HCRU and costs were tabulated for each subgroup and for the entire cohort. Results A total of 1049 patients met the study inclusion criteria (mean age, 70.9 years; 84.8% male). Across the different subgroups, patients showing MIBC evidence had more than two times higher hospitalization rates compared to the other subgroups. Overall, the entire BCG-treated cohort's total direct medical cost including hospitalizations, outpatient care and drugs was €33.9 million and €9250 per patient-year. Cost for patients with MIBC evidence was much higher, at €17,983 per patient-year, than patients with No further NMIBC treatment (€6617) and patients with Continuous treatment for NMIBC (€7786). Across the subgroups, hospitalization was the largest driver of cost and contributed the most to cost for those with MIBC evidence. Conclusion The overall cost burden of this BCG-treated cohort of 1049 patients is high (€38 million whereof 4.1 million are indirect costs) over a mean follow-up of 3.9 years; economic burden is especially substantial for patients who fail BCG treatment and those who progress.

Economic Outcomes of Hexaminolevulinate Blue-Light Cystoscopy in Non-Muscle Invasive Bladder Cancer: A 5-Year, Medicare-Based Model. Bladder Cancer 2023.

Abstract
BACKGROUND: Bladder cancer is the most expensive cancer to treat on a per-patient basis. Blue light cystoscopy with hexaminolevulinate (BLC) has demonstrated improved diagnostic accuracy compared with white light cystoscopy (WLC) in non-muscle invasive bladder cancer (NMIBC). With higher upfront costs, questions remain about long-term BLC cost outcomes. OBJECTIVE: This study seeks to investigate the 5-year cost comparison of BLC and WLC from the Medicare payer perspective. METHODS: A representative 5-year NMIBC management model was constructed and Medicare reimbursement values were overlaid. The primary outcome was mean year-over-year cumulative cost discounted to present value at a 3% annual percentage rate. The secondary outcome was the rate of clinical events. RESULTS: Patients in the BLC cohort experienced fewer recurrences. On a cumulative present value cost basis, BLC was more expensive per patient in years 1, 2, and 3 than WLC, however, in years 4 and 5, BLC was economically favorable. Year 5 BLC mean cumulative cost savings was $1,172 per patient. Overall, 31.6% of all patients in the BLC group generated cumulative cost savings compared to WLC at year 1 compared with 50.9% at the end of year 5. CONCLUSIONS: Despite a higher initial annual cost, a slight cumulative economic advantage of BLC is realized after surveillance year 3. Additionally, a greater proportion of patients who received BLC achieved cost savings at the end of year 5. As novel technology emerges, economic models can help health care systems predict associated costs and quality improvements.
