Abstract
Introduction: Electromotive Drug Administration (EMDA) amplifies drug delivery deep into targeted tissues. We tested, for the first time, the ability of EMDA to deliver methylene blue into the urothelium of the renal pelvis. Materials and Methods: In an anesthetized female pig, both proximal ureters were transected two inches distal to the ureteropelvic junction. An 8F dual lumen catheter and a 5F fenestrated catheter with an indwelling silver wire were inserted into both renal pelvises following which methylene blue (0.1%) was infused at a rate of 5 mL/min for 20 minutes. In one pelvis, a 4 mA positive pulsed electrical current was applied to the silver wire. Results: In contrast to the control pelvis, the EMDA side macroscopically exhibited dense homogeneous staining; microscopy revealed penetration of methylene blue into the urothelium/lamina propria. Conclusion: In the porcine renal pelvis, application of EMDA increased the penetration of a charged molecule into the urothelium/lamina propria.

Abstract
Introduction: Electromotive drug administration (EMDA) delivers a drug deeply into targeted tissues, such as the bladder. EMDA has never been applied to the ureter. Methods: In four in vivo porcine ureters, a unique EMDA catheter containing a silver conducting wire was advanced for the infusion of methylene blue. In two ureters, a pulsed current was delivered through an EMDA machine, whereas the other two ureters served as a control. After 20 minutes of infusion, the ureters were harvested. Results: In the EMDA ureter, there was diffuse staining of the urothelium; penetration of methylene blue occurred in the lamina propria and muscularis propria. In the control ureter, there was only patchy staining of the urothelium. Conclusion: In this first report of ureteral EMDA, a charged molecule penetrated beyond the urothelium into the lamina propria and muscularis propria of the porcine ureter.

Hyperthermic Mitomycin C in Intermediate-risk Non-muscle-invasive Bladder Cancer: Results of the HIVEC-1 Trial. Eur Urol Oncol 2023; 6:58-66. [PMID: 36435738 DOI: 10.1016/j.euo.2022.10.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2022] [Revised: 09/29/2022] [Accepted: 10/31/2022] [Indexed: 11/25/2022]
Abstract
BACKGROUND Optimising therapeutic strategies of intermediate-risk non-muscle-invasive bladder cancer (IR-NMIBC) is needed. OBJECTIVE To compare recurrence-free survival (RFS) with adjuvant intravesical mitomycin C (MMC) at normothermia or hyperthermia using the COMBAT bladder recirculation system at 43 °C for 30 and 60 min. DESIGN, SETTING, AND PARTICIPANTS A prospective open-label, phase 3 randomised controlled trial (HIVEC-1) accrued across 13 centres between 2014 and 2020 in Spain. After complete transurethral resection of the bladder and immediate postoperative MMC instillation, patients with IR-NMIBC were randomised (1:1:1) to four weekly followed by three monthly 40-mg MMC instillations at normothermia (control; n = 106), 43 °C for 30 min (n = 107), or 43 °C for 60 min (n = 106) were investigated. Therapeutic compliance was defined as four or more instillations. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The primary outcome was RFS at 24 mo in the intention-to-treat (ITT) and per-protocol (PP) populations. The secondary outcomes included progression-free survival at 24 mo, safety outcome measures, and changes in health-related quality of life. Log-rank, Fisher, χ2, and analysis of variance tests were used. RESULTS AND LIMITATIONS The ITT 24-mo RFS was 77% for control, 82% for 43 °C-30 min, and 80% for 43 °C-60 min (p = 0.6). The PP 24-mo RFS was 77% for control, 83% for 43 °C-30 min, and 80% for 43 °C-60 min (p = 0.59). Six patients progressed to muscle-invasive disease in the ITT population (four in the control, 43 °C-30 min, and 43 °C-60 min groups each) and four in the PP population (all controls). Serious adverse events occurred in 26 patients (8.1%), and we were unable to demonstrate a difference between groups (p = 0.5). Adverse events, mainly dysuria and spasms, occurred in 124 patients (33% in control, 35% in 43 °C-30 min, and 48% in 43 °C-60 min; p = 0.05). The total International Prostate Symptom Score worsened by 1.2 ± 7.3 points, similarly across groups (p = 0.29). The Functional Assessment of Cancer Therapy-Bladder domains and indexes showed no significant change. CONCLUSIONS Four-month adjuvant hyperthermic MMC using the COMBAT system for 30 and 60 min in IR-NMIBC is well tolerated, but we did not find it to be superior to normothermic MMC at 24 mo. PATIENT SUMMARY We were unable to demonstrate the effectiveness of hyperthermia using the COMBAT system in intermediate-risk non-muscle-invasive bladder cancer. Further evaluation of long-term recurrence and progression, and maintenance regimens appears mandatory.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:10825.

Abstract
BACKGROUND Conventional and newly emerged intravesical modalities have demonstrated prophylactic effectiveness that may improve quality of life (QoL) in non-muscle invasive bladder cancer. The purpose of this study is to analyze existing QoL evidence in patients receiving any form of intravesical therapy. METHODS A PubMed search without time restriction was conducted to identify all relevant studies in accordance with the PICOT question. Additionally, a search was also performed in the Cochrane library database, Internet, and citation. The CONSORT 2010 checklist and STROBE statement checklist were used to evaluate the risk of bias of the included studies. RESULTS A total of 24 eligible articles were included, which consisted of 11 interventional and 13 observational studies. Intravesical therapy with Bacillus Calmette-Guérin (BCG) or certain chemotherapeutic agents worsens symptom burdens and functional performance during the initial induction phase while continuous improved is observed throughout the maintenance treatment and beyond. Hyperthermia has shown a positive trend in enhancing QoL of patients receiving intravesical chemotherapy, which requires more investigations. However, QoL data were unavailable for other forms of immunotherapy, immune checkpoint inhibitors, electromotive drug administration, and photodynamic therapy. CONCLUSIONS Limited studies suggested the long-term positive impact of intravesical BCG immunotherapy and chemotherapy. However, existing evidence was lacking to clarify the impact of many emerging intravesical therapies that have suggested to be effective and safe, which demands treatment-specific QoL studies.

Abstract
Introduction Non-muscle-invasive bladder cancer (NMIBC) is a common and heterogeneous disease; many patients develop recurrent or progress to muscle-invasive disease. Intravesical drug therapy is a pillar in the current management of NMIBC; notwithstanding, Mitomycin C (MMC) and Bacillus Calmette-Guérin (BCG) have numerous limitations including international supply issues, and local and systemic toxicity. Here we review novel intravesical therapeutic options and drug delivery devices with potential for clinical use in the treatment of NMIBC. Methods PubMed, ClinicalTrials.gov and Cochrane Library searches were undertaken. Systematic reviews, meta-analyses, randomised controlled trials, single-arm clinical trials and national/international conference proceedings were included. Results Novel intravesical drugs, including chemotherapeutic agents, immune checkpoint inhibitors, monoclonal antibodies and gene therapies, have demonstrated varying efficacy in the treatment of NMIBC. Current evidence for the majority of treatments is mostly limited to single-arm trials in patients with recurrent NMIBC. Various novel methods of drug delivery have also been investigated, with encouraging preliminary results supporting the intravesical delivery of hyperthermic MMC and MMC hydrogel formulations. Conclusions Novel therapeutic agents and drug delivery systems will be important in the future intravesical management of NMIBC. As our understanding of the molecular diversity of NMIBC develops, molecular subtyping will become fundamental in the personalisation of intravesical treatments. Further randomised studies are urgently required to investigate the efficacy of novel intravesical treatments and novel regimens, in comparison to current standards-of-care, particularly in the context of international BCG shortages.

Abstract
Interstitial cystitis is an underdiagnosed chronic-relapsing to chronic-progressive urinary bladder disease, whose pathogenesis and aetiology has not been fully elucidated. The disease itself cannot be cured and treatment is symptomatic. Treatment options comprise conservative and medicinal approaches as well as a large number of interventional/surgical procedures. These include intravesical instillation, transurethral procedures such as injections of botulinum toxin A, corticosteroids and local anaesthetics, hydrodistension and neuromodulation as well as (laser) fulguration, resection and cystectomy. Although surgical procedures are considered a late option and are often referred to as last-resort therapy, these interventional options often show good to very good response rates, manageable complications and a favourable risk-benefit evaluation. An overall generalisation of surgery as a last-resort treatment option should therefore be avoided and its use should be discussed based on the individual needs of each patient.

Abstract
Supplies of intravesical Bacillus Calmette-Guérin (BCG), the first-line treatment for most intermediate- and high-risk non-muscle-invasive bladder cancers (NMIBC), have proven unreliable over the past decade. This review considers the evolution of BCG immunotherapy for NMIBC: from the discovery of the antitumour side effects of tuberculosis and subsequently the BCG vaccine, to recent advances in novel immunotherapeutic agents. We summarize the evidence for alternative options to standard intravesical BCG therapy regimens and describe the potential for immune response manipulating drugs in the treatment of NMIBC. These new agents, including immune checkpoint inhibitors, toll-like receptor agonists and recombinant viral vectors, may provide better options in the management of NMIBC in the future.

Abstract
To review all published evidence regarding the use of Electromotive Drug Administration (EMDA) for the management of urological conditions, focusing on efficacy and safety, and highlighting areas that require further study. The PubMed and Medline databases were searched up to July 23, 2019. All studies reporting the use of EMDA to enhance the intravesical administration of therapeutic drugs for urological conditions were included. Two reviewers independently screened all articles, searched the reference lists of retrieved articles, and performed the data extraction. Thirty-two studies were included. The use of EMDA has been reported in the following urological conditions: (1) nonmuscle-invasive bladder cancer (NMIBC); (2) overactive bladder; (3) bladder pain syndrome; (4) radiation cystitis; (5) detrusor acontractility; and (6) for analgesia prior to transurethral procedures. Overall, most studies are nonrandomized trials with small numbers of patients. The use of EMDA is reported to be safe and effective in all these conditions, with the highest level of evidence in NMIBC in the neoadjuvant and adjuvant setting. However, the low overall quality of evidence limits the conclusions that can be reached. The use of EMDA to improve the efficacy of intravesical treatments is promising, but the low overall quality of the evidence base has limited its widespread use. Future studies should compare EMDA to passive diffusion and current standard of care in large, randomized, and long-term studies to determine the efficacy, safety, and cost-effectiveness of this modality.

Abstract
Objective To evaluate the effectiveness of electro-mediated drug administration of mitomycin C (EMDA/MMC) after transurethral resection of the bladder tumour (TURBT) in preventing non-muscle-invasive bladder cancer (NMIBC) recurrence and progression and to explore clinical and demographic factors associated with treatment response. Patients and methods Between April 2016 and August 2019, 112 patients diagnosed with intermediate- or high-risk NMIBC underwent a TURBT followed by an EMDA/MMC treatment. The percentage of treatment responders and progression-free survivors at 3 and 6 months were evaluated. Results Follow-up data were available for 101 patients (90%) at 3 months and 92 (82%) at 6 months. Response rates to EMDA/MMC treatment were 85% at 3 months and 75% at 6 months, and progression-free rates were 94% and 90%, respectively. No statistically significant differences were seen between intermediate- and high-risk patients. A higher risk of tumour recurrence and progression was associated with previous Bacillus Calmette–Guérin (BCG) failure. According to the Clavien–Dindo classification, only low-grade complications were observed. Conclusions EMDA/MMC after TURBT was associated with high response and progression-free rates at 3 and 6 months, with only low-grade adverse events. These results confirm the efficacy and safety of EMDA/MMC as a therapeutic option for both intermediate- and high-risk patients. However, patients with BCG failure responded poorly to EMDA/MMC.

Abstract
PURPOSE OF REVIEW To give an overview of current options for conservative treatment of patients failing intravesical bacillus Calmette-Guerin (BCG) and to discuss emerging approaches with potential future clinical applications. RECENT FINDINGS Radical cystectomy is the standard-of-care for patients failing BCG therapy. In patients unfit or unwilling to undergo surgery, salvage therapy options could be proposed with the aim to offer local cancer control and prevent progression to muscle-invasive disease. Salvage treatments have been conducted using intravesical chemotherapy regimens, chemoradiation or chemohyperthermia. Intravesical agents such as valrubicin, gemcitabine or docetaxel showed response rates varying between 16 and 40%, whereas combination treatments of gemcitabine with docetaxel or mitomycin reported response rates in up to 50% of all patients with durable responses in about one out of three patients. For chemohyperthermia, 2-year recurrence rates between 41 and 56% have been reported. Ongoing clinical trials are evaluating chemoradiation as well as novel approaches such as systemic immunotherapy, viral gene therapy, targeted therapy or vaccination strategies with promising preliminary outcomes. SUMMARY Salvage therapeutic bladder-sparing strategies for BCG failure such as intravesical chemotherapy or chemoradiation should currently only be considered in patients unfit for or refusing surgery. Innovative concepts such as chemohyperthermia, checkpoint inhibitors, targeted therapy or viral gene therapy could lead to major changes in clinical management of BCG failures in the future.

Abstract
Cystoscopic onabotulinumtoxinA (onaBoNTA) intradetrusor injection is an efficient and durable modality for treating sensory bladder disorders. However, the inconvenience of using the cystoscopic technique and anesthesia, and the adverse effects of direct needle injection (e.g., haematuria, pain, and infections) have motivated researchers and clinicians to develop diverse injection-free procedures to improve accessibility and prevent adverse effects. However, determining suitable approaches to transfer onaBoNTA, a large molecular and hydrophilic protein, through the impermeable urothelium to reach therapeutic efficacy remains an unmet medical need. Researchers have provided potential solutions in three categories: To disrupt the barrier of the urothelium (e.g., protamine sulfate), to increase the permeability of the urothelium (e.g., electromotive drug delivery and low-energy shock wave), and to create a carrier for transportation (e.g., liposomes, thermosensitive hydrogel, and hyaluronan-phosphatidylethanolamine). Thus far, most of these novel administration techniques have not been well established in their long-term efficacy; therefore, additional clinical trials are warranted to validate the therapeutic efficacy and durability of these techniques. Finally, researchers may make progress with new combinations or biomaterials to change clinical practices in the future.

Abstract
BACKGROUND People with urothelial carcinoma of the bladder are at risk for recurrence and progression following transurethral resection of a bladder tumour (TURBT). Mitomycin C (MMC) and Bacillus Calmette-Guérin (BCG) are commonly used, competing forms of intravesical therapy for intermediate- or high-risk non-muscle invasive (Ta and T1) urothelial bladder cancer but their relative merits are somewhat uncertain. OBJECTIVES To assess the effects of BCG intravesical therapy compared to MMC intravesical therapy for treating intermediate- and high-risk Ta and T1 bladder cancer in adults. SEARCH METHODS We performed a systematic literature search in multiple databases (CENTRAL, MEDLINE, Embase, Web of Science, Scopus, LILACS), as well as in two clinical trial registries. We searched reference lists of relevant publications and abstract proceedings. We applied no language restrictions. The latest search was conducted in September 2019. SELECTION CRITERIA We included randomised controlled trials (RCTs) that compared intravesical BCG with intravesical MMC therapy for non-muscle invasive urothelial bladder cancer. DATA COLLECTION AND ANALYSIS Two review authors independently screened the literature, extracted data, assessed risk of bias and rated the quality of evidence according to GRADE per outcome. In the meta-analyses, we used the random-effects model. MAIN RESULTS We identified 12 RCTs comparing BCG versus MMC in participants with intermediate- and high-risk non-muscle invasive bladder tumours (published from 1995 to 2013). In total, 2932 participants were randomised. Time to death from any cause: BCG may make little or no difference on time to death from any cause compared to MMC (hazard ratio (HR) 0.97, 95% confidence interval (CI) 0.79 to 1.20; participants = 1132, studies = 5; 567 participants in the BCG arm and 565 in the MMC arm; low-certainty evidence). This corresponds to 6 fewer deaths (40 fewer to 36 more) per 1000 participants treated with BCG at five years. We downgraded the certainty of the evidence two levels due to study limitations and imprecision. Serious adverse effects: 12/577 participants treated with BCG experienced serious non-fatal adverse effects compared to 4/447 participants in the MMC group. The pooled risk ratio (RR) is 2.31 (95% CI 0.82 to 6.52; participants = 1024, studies = 5; low-certainty evidence). Therefore, BCG may increase the risk for serious adverse effects compared to MMC. This corresponds to nine more serious adverse effects (one fewer to 37 more) with BCG. We downgraded the certainty of the evidence two levels due to study limitations and imprecision. Time to recurrence: BCG may reduce the time to recurrence compared to MMC (HR 0.88, 95% CI 0.71 to 1.09; participants = 2616, studies = 11, 1273 participants in the BCG arm and 1343 in the MMC arm; low-certainty evidence). This corresponds to 41 fewer recurrences (104 fewer to 29 more) with BCG at five years. We downgraded the certainty of the evidence two levels due to study limitations, imprecision and inconsistency. Time to progression: BCG may make little or no difference on time to progression compared to MMC (HR 0.96, 95% CI 0.73 to 1.26; participants = 1622, studies = 6; 804 participants in the BCG arm and 818 in the MMC arm; low-certainty evidence). This corresponds to four fewer progressions (29 fewer to 27 more) with BCG at five years. We downgraded the certainty of the evidence two levels due to study limitations and imprecision. Quality of life: we found very limited data for this outcomes and were unable to estimate an effect size. AUTHORS' CONCLUSIONS Based on our findings, BCG may reduce the risk of recurrence over time although the Confidence Intervals include the possibility of no difference. It may have no effect on either the risk of progression or risk of death from any cause over time. BCG may cause more serious adverse events although the Confidence Intervals once again include the possibility of no difference. We were unable to determine the impact on quality of life. The certainty of the evidence was consistently low, due to concerns that include possible selection bias, performance bias, given the lack of blinding in these studies, and imprecision.

Abstract
Part 1 of this two-part article provides an overview of bladder cancer and discusses its management. Since publication of a previous article entitled 'Understanding the role of smoking in the aetiology of bladder cancer' ( Anderson, 2009 ), the author has received many requests for an update. This article provides an overview of bladder cancer and its current management practices, underlining the continued role of smoking as the predominant risk factor in the disease's development. The management of bladder cancer is governed by specific guidelines. Management of non-muscle-invasive cancers, including surgical intervention with transurethral resection, and intravesical therapy using chemotherapy and immunotherapy agents, is discussed. Cystectomy (removal of the bladder), is sometimes necessary. Treatments are effective in reducing tumour recurrence, but the effects of the risks and side-effects on the individual's quality of life can be significant. The prevalence of bladder cancer, and the nature of its management make this cancer one of the most expensive for the NHS to treat. The effectiveness of health promotional strategies in increasing peoples' awareness of their risk of developing the disease, and in enabling them to change long-term health behaviours is discussed. The role of the multidisciplinary team is explored, along with that of the uro-oncology cancer nurse specialist. Part 2 will consider the management of muscle-invasive and metastatic bladder cancer.

Abstract
Bladder cancer (BC) is one of the leading causes of cancer-related deaths worldwide. Despite, the majority of the cases were diagnosed as non-muscle invasive bladder cancer (NMIBC) with favorable prognosis, it has tendency to recur or progress to a higher grade or stage. The first line treatment of patients with NMIBC is transurethral resection with adjuvant therapies primarily intravesical Bacillus Calmette-Guérin (BCG) immunotherapy. However, in a portion of patients whose BCG treatment failed, alternative treatments may be required. Furthermore, intravesical BCG may be contraindicated in or untolerated by a group of patients. For these patients, some treatment options are readily available and a variety of them are currently under clinical investigation. In this review, these alternative therapies have been summarized.

Abstract
INTRODUCTION Non-muscle invasive bladder cancer (NMIBC) is a common disease process with a high propensity for recurrence and risk of progression to muscle-invasive or systemic disease. Optimal management of NMIBC depends on appropriate resection and staging, risk-based use of intravesical therapy and tailored surveillance. Current challenges include compliance with guideline recommendations and cancers which are refractory to standard therapies. Areas covered: This review summarizes the conventional management of NMIBC - which relies on strict cystoscopic surveillance and intravesical therapies with chemotherapy and/or immunotherapy in the form of bacillus Calmette-Guerin (BCG). As many patients will be resistant to conventional treatment, investigational therapies and novel prognostic models will also be discussed. Expert commentary: For decades, the management of NMIBC has been predicated on intravesical therapies, most often through the instillation of BCG which has proven clinical efficacy over transurethral resection alone. Despite this, many patients will recur or progress after BCG therapy. While radical cystectomy remains the standard for such patients, suitable alternatives are being actively investigated. An increased interest in immunotherapy for malignancy has reinvigorated this field and on-going advances in disease prognostication are likely to improve upon the existing treatment paradigms for NMIBC.

Abstract
Although many treatment modalities and schedules for non-muscle-invasive bladder cancer (NMIBC) exist, all yet prove to have limitations. Therefore the search for new forms of therapy continues. One of these forms consists of combining intravesical chemotherapy, typically mitomycin C (MMC), with hyperthermia achieved by a microwave-applicator. We aimed to review the current status of intravesical radiofrequency (RF) induced chemohyperthermia (CHT) for NMIBC with regard to efficacy, adverse-events (AEs) and its future perspective. A search for RF-induced CHT in MEDLINE, Embase, Cochrane and ClinicalTrials.gov databases was performed. Relevant conference abstracts were searched for manually. If applicable, experts on the area were consulted. Papers were selected based on abstract and title. A table of newly published clinical trials since 2011 was constructed. No meta-analysis could be performed based on these new papers. Efficacy proved to be better for RF-induced CHT compared to both MMC alone and bacillus Calmette-Guérin (BCG) instillations, with the latter being based on just one abstract of a randomised controlled trial. The AE rate in CHT is higher compared to MMC instillation, but is similar compared to BCG, albeit different in the type of AE. In almost all studies no severe AEs are reported. Although heterogeneity in methodology exists, RF-induced CHT seems promising. However, alternative methods of applying hyperthermia are starting to present their first results, imposing as effective options too. Intravesical RF-induced CHT may become an alternative for BCG instillation, and possibly for cystectomy, although further level 1 evidence is required for both reliable and reproducible data on efficacy and adverse events.

Abstract
PURPOSE We report for the first time the activity and safety of Unithermia(®) (Elmedical Ltd, Hod-Hasharon, Israel), a novel device for administration of MMC-C with hyperthermia (HT), that employs conductive heating, in a series of non-grade 3 non-muscle-invasive bladder cancer (NMIBC) that failed Bacillus Calmette-Guerin (BCG). METHODS Patients with non-grade 3 NMIBC recurring after at least a full induction course of BCG were eligible for this phase I-II prospective single-arm study. Six weekly instillations with Unithermia(®) were scheduled following complete TUR. Primary end points were treatment safety and response rate (RR), and the latter defined as the absence of any unfavourable outcome at 12 months. Any grade 3 and/or muscle-invasive (T > 1) recurrence was considered disease progression. Kaplan-Meier estimation of the time to recurrence and progression, cancer-specific survival and overall survival was taken as secondary end points. RESULTS Thirty-four eligible patients entered the study between January 2009 and April 2011. RR was documented in 20/34 (59%). Among the 14/34 (41%) non-responders, four developed G3 disease, one developed carcinoma in situ, and one progressed to muscle-invasive bladder cancer, with an overall 18% progression rate at 1 year. At a median follow-up of 41 months, recurrence and progression rates were 35.3 and 23.5%, respectively. Toxicity did not go beyond grade 2 except in five cases. CONCLUSIONS Initial experience with MMC-HT with Unithermia(®) showed an interesting activity and safety profile in non-grade 3 NMIBC recurring after BCG, suggesting a role as second-line therapy in this selected subgroup of NMIBC.
