Abstract
The high recurrence rate and poor prognosis of non-muscle invasive bladder cancer (BC) are challenges that need to be urgently addressed. Transurethral cystectomy for bladder tumors is often combined with bladder perfusion therapy, which can effectively reduce the recurrence and progression rates of BC. The present review integrated and analyzed currently available bladder perfusion drugs, mainly including chemotherapeutic agents, immunotherapeutic agents and other adjuvant perfusion drugs. Bacillus Calmette-Guerin (BCG) perfusion was the pioneering immunotherapy for early BC and still ranks high in the selection of perfusion drugs. However, BCG infusion has a high toxicity profile and has been shown to be ineffective in some patients. Due to the limitations of BCG, new bladder perfusion drugs are constantly being developed. Immunotherapeutic agents have opened a whole new chapter in the selection of therapeutic agents for bladder perfusion. The present review explored the mechanism of action, clinical dosage and adverse effects of a variety of bladder perfusion drugs currently in common use, described combined perfusion and compared the effects of certain drugs on BC.

Combination of hyperthermia and intravesical chemotherapy for the treatment of pT1 stage bladder cancer: A retrospectively clinical study. Asia Pac J Clin Oncol 2024; 20:228-233. [PMID: 36656047 DOI: 10.1111/ajco.13931] [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: 11/05/2021] [Revised: 12/27/2022] [Accepted: 01/04/2023] [Indexed: 01/20/2023]
Abstract
PURPOSE To evaluate the efficiency and safety of combined local bladder hyperthermia and intravesical chemotherapy (IVC) for the treatment of patients with pT1 stage bladder cancer. METHOD A total of 189 patients with pT1 who underwent transurethral resection of bladder cancer (TURBT) were retrospectively reviewed. After TURBT, the patients with low-grade urothelial carcinoma (UC) were treated with either an IVC with pirarubicin (THP) protocol or chemo-thermotherapy (CHT) with THP protocol, whereas patients with high-grade UC were treated with either an intravesical immunotherapy (IVI) with bacillus Calmette-Guerin (BCG) protocol or CHT protocol, patients' characteristics, tumor biological features, and follow-up data were analyzed and compared between CHT and IVC group in low-grade UC, CHT, and IVI group in high-grade UC, respectively. RESULTS The median follow-up time was 24 months. In patients with low-grade UC, the median recurrence free survival (RFS) interval and costs of treatment in CHT group were significantly higher than those in IVC group (p = .01, p < .001, respectively), CHT was associated with higher RFS compared with IVC by Kaplan-Meier analysis, and three patients in IVC group upgraded to high grade when tumor recurred, whereas no cases were found upgraded in CHT group, p = .38. In patients with high-grade UC, tumor recurrence rates at 12 (p = .004) and 24 months (p = .004) after TURBT, rate of complications (p = .04)-especially for hematuresis (p = .03) and irritation symptoms (p = .04)-the median costs of treatment (p < .001) in CHT group were significantly lower than those in IVI group, RFS interval, health-related quality of life) at 12 and 24 months after TURBT in CHT group was significantly higher than those in IVI group (p < .001, p = .002, and p < .001, respectively), and CHT was associated with higher RFS compared with IVI by Kaplan-Meier analysis. The rate of patients upstaged to pT2 in CHT group seemed lower than that in IVI group, but there was no significantly statistical difference (14.3% vs. 24%, p = .58). CONCLUSION CHT has a beneficial prophylactic effect in patients with pT1 bladder cancer, especially in patients with high-grade UC, which is much more effective and safer than BCG, meanwhile it costs less compared with BCG.

Abstract
Bladder cancer encapsulates a wide spectrum of disease severities, with non-muscle invasive bladder cancer (NMIBC) representing an entirely different entity from muscle-invasive disease. Bacillus Calmette-Guérin (BCG) is one of the most successful intravesical treatment methods for patients diagnosed. However, a considerable proportion of patients fail to respond to BCG treatment. Given the propensity for recurrence in patients with high-risk bladder cancer, these patients present with surgical dilemmas. There is currently no gold standard for salvage treatment post-BCG failure or unified definition as to what that means. In this review, we discuss the mechanisms of action and pathophysiology of BCG, potential theories behind BCG failure, and the scope of novel treatments for this surgical conundrum.

Abstract
PURPOSE To compare adjuvant hyperthermic intravesical chemotherapy (HIVEC) with mitomycin C and standard Bacillus Calmette-Guerin (BCG) therapy in terms of oncological outcomes and adverse events in patients with high-risk non-muscle-invasive bladder cancer (NMIBC). MATERIALS AND METHODS The data of patients with high-risk papillary NMIBC treated with adjuvant intravesical BCG instillations or HIVEC in our institution between June 2017 and August 2022 were analyzed retrospectively. Twenty-four patients who received HIVEC were matched 1:1 with patients receiving BCG therapy based on tumor characteristics (tumor stage and grade), age, gender, smoking status, and the number of tumors (single or multiple). HIVEC and standard BCG treatments were compared in terms of recurrence-free survival (RFS), progression-free survival (PFS), and adverse events. RESULTS Forty-eight patients (24 in the BCG group and 24 in the HIVEC group) were included in the study. The median follow-up times of the BCG and HIVEC groups were 32 [interquartile range (IQR): 28.0-47.8] and 28 (IQR: 16.7-41.8) months, respectively (p = 0.11). There was no significant difference between the groups in terms of the 24-month RFS (BCG 83% vs HIVEC 88%, p = 0.64) and the 24-month PFS (BCG 100% vs HIVEC 94%, p = 0.61). Regarding the safety profile, at least one adverse event occurred in 13 (54%) of the patients in the BCG group and 12 (50.0%) of those in the HIVEC group (p = 0.77). CONCLUSION This study demonstrated that HIVEC with mitomycin C has a similar oncological efficacy and safety profile to standard BCG therapy in high-risk NMIBC.

Abstract
Bladder cancer is a heterogeneous disease. Treatment decisions are mostly decided based on disease stage (non-muscle invasive or muscle invasive). Patients with muscle-invasive disease will be offered a radical treatment combined with systemic therapy, while in those with non-muscle-invasive disease, an attempt to resect the tumor endoscopically will usually be followed by different intravesical instillations. The goal of intravesical therapy is to decrease the recurrence and/or progression of the tumor. In the current landscape of bladder cancer treatment, BCG is given intravesically to induce an inflammatory response and recruit immune cells to attack the malignant cells and induce immune memory. While the response to BCG treatment has changed the course of bladder cancer management and spared many "bladders", some patients may develop BCG-unresponsive disease, leaving radical surgery as the best choice of curative treatment. As a result, a lot of effort has been put into identifying novel therapies like systemic pembrolizumab and Nadofaragene-Firadenovac to continue sparing bladders if BCG is ineffective. Moreover, recent logistic issues with BCG production caused a worldwide BCG shortage, re-sparking interest in alternative BCG treatments including mitomycin C, sequential gemcitabine with docetaxel, and others. This review encompasses both the historic and current role of BCG in the treatment of non-muscle-invasive bladder cancer, revisiting BCG alternative therapies and reviewing the novel therapeutics that were approved for the BCG-unresponsive stage or are under active investigation.

Abstract
PURPOSE To investigate the effectiveness and safety of device-assisted intravesical chemotherapy compared to Bacillus Calmette-Guerin (BCG) in the treatment of patients with intermediate- and high-risk non-muscle-invasive bladder cancer (NMIBC). METHODS In February 2023, a systematic search was conducted on the PubMed, Cochrane, and Embase databases. Following the PRISMA guidelines, a systematic review and meta-analysis of the primary outcomes of interest were performed. The review was prospectively registered on PROSPERO under the registration number CRD42023398559. RESULTS A total of 10 studies involving 1160 patients were included. The results of the meta-analysis showed that compared to BCG, device-assisted chemotherapy had a lower recurrence rate (OR: 0.63, 95% CI: 0.48-0.84, p = 0.001), longer recurrence-free survival (OR: 0.64, 95% CI: 0.47-0.88, p = 0.006), and lower incidence of fever (OR: 0.18, 95% CI: 0.08-0.44, p = 0.0002). However, no significant differences were observed between the two groups in terms of progression, overall survival, progression-free survival, disease-free survival, overall adverse events, serious adverse events, hematuria, allergy, and general discomfort. Subgroup analysis revealed that neither chemohyperthermia (CHT) nor electromotive drug administration (EMDA) showed statistically significant differences in oncological outcomes compared to BCG. Regarding adverse events, both CHT and EMDA groups showed lower rates of fever compared to the BCG group (OR: 0.26, 95% CI: 0.10-0.67, p = 0.005, and OR: 0.14, 95% CI: 0.05-0.37, p < 0.0001, respectively). No significant differences were observed in the remaining adverse events between either the CHT or EMDA group and the BCG group. CONCLUSION Device-assisted intravesical chemotherapy appears to be a safe and viable alternative to BCG for patients with intermediate and high-risk NMIBC, showing comparable oncological outcomes and adverse events.

Abstract
CIS of the bladder is associated with a high risk of progression. In the case of BCG failure, radical cystectomy should be performed. For patients who refuse or are ineligible, bladder-sparing alternatives are evaluated. This study aims to investigate the efficacy of Hyperthermic IntraVesical Chemotherapy (HIVEC) depending on the presence or absence of CIS. This retrospective, multicenter study was conducted between 2016 and 2021. Patients with non-muscle-invasive bladder cancer (NMIBC) with BCG failure received 6-8 adjuvant instillations of HIVEC. The co-primary endpoints were recurrence-free survival (RFS) and progression-free survival (PFS). A total of 116 consecutive patients met our inclusion criteria of whom 36 had concomitant CIS. The 2-year RFS rate was 19.9% and 43.7% in patients with and without CIS, respectively (p = 0.52). Fifteen patients (12.9%) experienced progression to muscle-invasive bladder cancer with no significant difference between patients with and without CIS (2-year PFS rate = 71.8% vs. 88.8%, p = 0.32). In multivariate analysis, CIS was not a significant prognostic factor in terms of recurrence or progression. In conclusion, CIS may not be considered a contraindication to HIVEC, as there is no significant association between CIS and the risk of progression or recurrence after treatment.

Abstract
BACKGROUND Devices that increase the penetration of intravesical chemotherapeutic agents have been developed as alternatives to the use of bacillus Calmette-Guérin, in short supply at a time of increasing global incidence of non-muscle invasive bladder cancer (NMIBC). We performed a prospective observational study to compare 2 of these devices in the treatment of patients with high- and intermediate-risk NMIBC. The primary endpoint was the recurrence-free rate. Secondary endpoints were the rate of progression and adverse events. METHODS After undergoing transurethral bladder resection, 98 patients were selected to receive 1 of 2 treatments: hyperthermic intravesical chemotherapy (HIVEC) treatment with 40 mg of mitomycin C (MMC) using Combat BRS System V2.0 at 43 ± 0.5°C and 200 ml/min for 60 minutes (56 patients) or electromotive drug administration (EMDA) with 40 mg of MMC at 20 mA for 30 minutes (42 patients). The treatment schemes were similar: 6 weekly instillations as induction and 6-monthly instillations as maintenance. The recurrence rates were evaluated at 6 and 12 months and the progression rates at 12 months. RESULTS The recurrence-free rate at 12 months was 91,1% in the HIVEC group and 88.1% in the EMDA group (P ≥ 0.05). After the 12-month follow-up, only 1 progression occurred in each treatment group. In terms of adverse events, no significant differences were found between the treatments. CONCLUSIONS HIVEC and EMDA techniques are comparable in terms of recurrence, progression and adverse events at 12 months in the treatment of patients with high- and intermediate-risk NMIBC.

Abstract
For decades, the antineoplastic potential of hyperthermia alone or in combination with radiotherapy and/or chemotherapy has been subject of intensive preclinical and clinical research in various tumor entities. The clinical evidence on the beneficial effects of additional hyperthermia in combination with intravesical Mitomycin C for superficial non-muscle-invasive bladder cancer as well as for deep regional microwave hyperthermia techniques applied during an external beam radiotherapy or chemoradiation treatment for more advanced tumors are summarized. In some series, deep regional hyperthermia in combination with an initial transurethral resection and Cisplatin-based chemoradiation increased the 5-year overall survival rates up to 20%. The presented data justifies a fresh irrespective chance for mild regional hyperthermia in the context of new progressive prospective trials on multimodality treatment for bladder preservation.

Abstract
Background Muscle invasive bladder urothelium carcinoma is a common urinary tract tumor. With the deepening of research, more and more treatment methods are applied in clinical practice, extending the life of patients. Among them, the clinical application of chemotherapeutic intravesical hyperthermia and tumor immunotherapy provides new ideas for our treatment. Case report An 81-year-old female patient was diagnosed with stage T2N0M0 bladder cancer in our hospital. Because the patient and her family were keen to preserve her bladder, they declined surgery and opted for combined chemotherapy. After informed consent from the patient and her family, she received cisplatin combined with gemcitabine intravesical hyperthermic infusion. But the side effects of cisplatin made her intolerable to chemotherapy. With their informed consent we changed her to intravenous tislelizumab in combination with gemcitabine intravesical hyperthermic infusion to continue her treatment. During the subsequent follow-up visits, we found a surprising effect of the treatment. Conclusion Gemcitabine intravesical hyperthermia therapy combined with intravenous tislelizumab in the treatment of muscle invasive bladder urothelium carcinoma may provide a new possible therapeutic strategy of some patients who are inoperable or refuse surgery.

[PMID: 37025474 PMCID: PMC10071075 DOI: 10.1002/bco2.203] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2022] [Accepted: 10/28/2022] [Indexed: 12/04/2022] Open
Abstract
Objectives The objectives of the study are to explore tolerability, acceptability and oncological outcomes for patients with high-risk non-muscle-invasive bladder cancer (NMIBC) treated with hyperthermic intravesical chemotherapy (HIVEC) and mitomycin-C (MMC) at our institution. Patients and Methods Our single-institution, observational study consists of consecutive high-risk NMIBC patients treated with HIVEC and MMC. Our HIVEC protocol included six weekly instillations (induction), followed by two further cycles of three instillations (maintenance) (6 + 3 + 3) if there was cystoscopic response. Patient demographics, instillation dates and adverse events (AEs) were collected prospectively in our dedicated HIVEC clinic. Retrospective case-note review was performed to evaluate oncological outcomes. Primary outcomes were tolerability and acceptability of HIVEC protocol; secondary outcomes were 12-month recurrence-free, progression-free and overall survival. Results In total, 57 patients (median age 80.3 years) received HIVEC and MMC, with a median follow-up of 18 months. Of these, 40 (70.2%) had recurrent tumours, and 29 (50.9%) had received prior Bacillus Calmette-Guérin (BCG). HIVEC induction was completed by 47 (82.5%) patients, but only 19 (33.3%) completed the full protocol. Disease recurrence (28.9%) and AEs (28.9%) were the most common reasons for incompletion of protocol; five (13.2%) patients stopped treatment due to logistical challenges. AEs occurred in 20 (35.1%) patients; the most frequently documented were rash (10.5%), urinary tract infection (8.8%) and bladder spasm (8.8%). Progression during treatment occurred in 11 (19.3%) patients, 4 (7.0%) of whom had muscle invasion and 5 (8.8%) subsequently required radical treatment. Patients who had received prior BCG were significantly more likely to progress (p = 0.04). 12-month recurrence-free, progression-free and overall survival rates were 67.5%, 82.2%, and 94.7%, respectively. Conclusions Our single-institution experience suggests that HIVEC and MMC are tolerable and acceptable. Oncological outcomes in this predominantly elderly, pretreated cohort are promising; however, disease progression was higher in patients pretreated with BCG. Further randomised noninferiority trials comparing HIVEC versus BCG in high-risk NMIBC are required.

The clinical efficacy and safety of equipment-assisted intravesical instillation of mitomycin C after transurethral resection of bladder tumour in patients with nonmuscular invasive bladder cancer: A meta-analysis. PLoS One 2022; 17:e0276453. [PMID: 36269742 PMCID: PMC9586381 DOI: 10.1371/journal.pone.0276453] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2022] [Accepted: 10/07/2022] [Indexed: 11/06/2022] Open
Abstract
Background This review and meta-analysis aimed to systematically evaluate the clinical efficacy and safety of equipment-assisted intravesical instillation of mitomycin C (MMC) in patients with nonmuscular invasive bladder cancer (NMIBC) after transurethral resection of bladder tumour (TURBT). Methods The Embase, PubMed, CNKI, CBM, WANGFANG, VIP, Cochrane Library, and Clinicaltrial.com databases were searched for articles published before April 2022. The experimental group was treated with intravesical instillation of MMC assisted by equipment, including radiofrequency-induced thermochemotherapy, conductive thermochemical therapy, electromotive drug administration, or locoregional hyperthermia. The control group was treated with simple MMC perfusion. The outcomes of interest in the meta-analysis were recurrence, progression, side-effects, gross haematuria, and bladder irritation. Results A total of 15 studies that enrolled 1,190 patients were included in the meta-analysis. Compared to that of the control group, device-assisted intravesical instillation of MMC significantly reduced both tumour recurrence (odds ratio [OR] = 0.32, 95% confidence interval [CI] [0.24, 0.42], P <0.00001) and progression (OR = 0.29, 95% CI [0.12, 0.67], P = 0.004). There were no significant differences between the two groups in terms of safety (OR = 1.21, 95% CI [0.66,2.21], P = 0.54), bladder irritation (OR = 1.06, 95% CI [0.72,1.55], P = 0.78), or gross haematuria (OR = 1.11, 95% CI [0.64,1.94], P = 0.72). Conclusions Equipment-assisted intravesical instillation of MMC significantly reduced the recurrence and progression of patients with NMIBC who underwent TURBT and improved their quality of life. Given the significant heterogeneity in research quality and sample size among earlier studies, more prospective, multicentre, large sample randomized controlled trials are needed to supplement and verify this in the future.

Abstract
Gold nanorods (AuNRs) are ideal inorganic nanophotothermal agents with unique characteristics, including local surface plasmon resonance effects, easy scale preparation and functional modification, and good biocompatibility. This review summarizes several recent advances in AuNRs-based photothermal therapy (PTT) research. Functionalized AuNRs photothermal agents have optimized biocompatibility and targeting properties. The multifunctional AuNRs nanoplatform composite structure meets the requirements for synergistic effects of PTT, photoacoustic imaging, and other therapeutic methods. Photothermal therapy with AuNRs (AuNRs-PTT) is widely used to treat tumors and inflammatory diseases; its tumor-targeting, tumor metastasis inhibition, and photothermal tumor ablation abilities have remarkable curative effects. An in-depth study of AuNRs in living systems and the interactions between biological structure, nanomaterial, and near-infrared irradiation could lay the foundation for further clinical research and the broad application of AuNRs in PTT.

Abstract
PURPOSE OF REVIEW To critically analyze the oncological outcomes and safety profile of device-assisted intravesical chemotherapy studies reported in 2021. Studies were considered eligible if they included patients with nonmuscle invasive blood cancer (NMIBC), had a prospective or retrospective design, included at least 10 patients, were published in 2021, and assessed the oncological impact of device-assisted intravesical chemotherapy and/or reported standardized adverse effects (AEs). RECENT FINDINGS Eight new studies reported oncological outcomes after hyperthermic intravesical chemotherapy (HIVEC). In Bacillus Calmette-Guérin (BCG) naive patients, the reported 2-yr. recurrence-free survival (RFS) ranged from 70.7% to 82.4%, with one study reporting 2 yr. progression free survival (PFS) of 92%. In both BCG naive and BCG refractory patients, the reported 1-yr. RFS ranged from 60.5% to 70% and PFS was 94% in one study. For radiofrequency-induced HIVEC, the reported 5-yr. estimates were 38%for RFS and 91.5%for PFS. Regarding AEs, 10.2% of patients had severe AEs. Six studies reported AEs after HIVEC; the majorities were grade 1-2 AEs. SUMMARY Data coming from the studies published in the last years provides support for a consolidating role of device-assisted intravesical chemotherapy as a safe and effective alternative first- or second-line adjuvant treatment of patients with NMIBC.

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
Introduction: The recommended treatment for intermediate and high-risk nonmuscle invasive bladder cancer (NMIBC) is adjuvant intravesical bacillus Calmette–Guerin (BCG) instillation. However, up to 50% experience tumor recurrences even after adjuvant BCG, and many patients develop local or systemic adverse effects. Our study compared adverse effects, short-term recurrence rates, and cost-implications of BCG therapy to Hyperthermic Intra-VEsical Chemotherapy (HIVEC) with Mitomycin-C (MMC) in these patients. Materials and Methods: Retrospective analysis of intermediate and high-risk NMIBC patients who received either intravesical BCG or HIVEC® after transurethral resection of bladder tumor in our institute (January 2017 to March 2020) was done. Twenty-two patients who received HIVEC and 29 who received BCG were analyzed. We used SPSS Statistics v20.0 (IBM Corp., Armonk, NY, USA) software for the statistical analysis. Results: Nineteen (86.4%) patients in the HIVEC group had no adverse effects. Two (9.1%) patients had Grade I lower urinary tract symptoms (LUTS) treated symptomatically. One patient developed UTI after HIVEC, and further cycles were stopped (Grade II). BCG group had a higher rate of Grade III adverse effects in six (20.7%) patients. Median follow-up was 10.5 and 22 months. The tumor recurred in one (4.5%) and six (20.7%) patients in HIVEC and BCG groups, respectively. There was no difference in recurrence-free survival at 18 months and the cost for the HIVEC therapy was more. Conclusions: HIVEC with MMC is a reasonable adjuvant treatment option in NMIBC, which is well tolerated, albeit increased cost of the treatment. Randomized trials with more follow-up are required for further conclusion.

Abstract
Non-muscle invasive bladder cancer (NMIBC) has traditionally been managed with transurethral resection followed by intravesical chemotherapy and/or bacillus Calmette-Guerin (BCG) in a risk-adapted manner. These tumors commonly recur and can progress potentially to lethal muscle invasive disease. A major unmet need in the field of NMIBC is bladder preserving therapy for recurrent high-grade NMIBC after adequate intravesical BCG therapy. The current gold standard treatment for these BCG-unresponsive patients is radical cystectomy, which is associated with considerable morbidity and mortality, particularly in older and frailer patients. It is therefore critical to provide alternative treatment options with acceptable oncological outcomes. In this review we explore novel bladder-sparing treatment options including combination intravesical therapy, enhanced instillation methods, immunotherapy, gene therapy, targeted therapy, photodynamic therapy and BCG variants across the spectrum of NMIBC disease states, ranging from low grade BCG-naïve patients through to high-grade BCG-unresponsive NMIBC.

Abstract
Objective: Intravesical bacillus Calmette–Guérin (BCG) is the first-line treatment of choice for high-risk non-muscle-invasive bladder cancer (NMIBC). Our aim was to evaluate the long-term impact of BCG shortages on oncological outcomes. Methods: All patients undertaking an initial course of intravesical BCG for intermediate or high risk NMIBC at a single UK cancer centre between August 2012 and August 2014 were evaluated. Compliance was defined as completing 12 doses of BCG within the first year following diagnosis. Results: Due to BCG shortages, 25/114 (22%) patients were compliant with planned maintenance treatment. Compared to the compliant cohort, the non-compliant due to BCG shortages cohort had a higher rate of disease recurrence (35.3% vs. 24%), required more additional intravesical treatments (14.7% vs. 12%) and had a higher rate of radical cystectomy (11.8% vs. 4%). Disease-free survival was superior in the compliant cohort at two years (88% vs. 79.5%) and at 4.5 years (72% vs. 56.1%). There was no statistically significant difference, likely due to the sample size. Conclusions: The consequences of undertreatment due to BCG shortages can impact long-term cancer outcomes. Increased vigilance, robust long-term surveillance and alternative treatment strategies are required for NMIBC patients affected by shortages in BCG supplies. Level of evidence: Level 2b

Abstract
AIM This review article summarizes the current clinical practice guidelines around disease definitions and risk stratifications, and the treatment of non-muscle-invasive bladder cancer (NMIBC). Recently completed and ongoing clinical trials of novel and investigational therapies in Bacillus Calmette-Guérin (BCG)-naïve, BCG-recurrent, and BCG-unresponsive patient populations are also described, e.g., those involving immune checkpoint inhibitors, targeted therapies, other chemotherapy regimens, vaccines, and viral- or bacterial-based treatments. Finally, a brief overview of enhanced cystoscopy and drug delivery systems for the diagnosis and treatment of NMIBC is provided. BACKGROUND A global shortage of access to BCG is affecting the management of BCG-naïve and BCG-recurrent/unresponsive NMIBC; hence, there is an urgent need to assist patients and urologists to enhance the treatment of this disease. METHODS Searches of ClinicalTrials.gov, PubMed, and Google Scholar were conducted. Published guidance and conference proceedings from major congresses were reviewed. CONCLUSION Treatment strategies for NMIBC are generally consistent across guidelines. Several novel therapies have demonstrated promising antitumor activity in clinical trials, including in high-risk or BCG-unresponsive disease. The detection, diagnosis, surveillance, and treatment of NMIBC have also been improved through enhanced disease detection.

Abstract
OBJECTIVE As a newly developed technique, focused microwave breast hyperthermia (FMBH) can provide accurate and cost-effective treatment of breast tumors with low side effect. A clinically feasible FMBH system requires a guidance technique to monitor the microwave power distribution in the breast. Compressive thermoacoustic tomography (CTT) is a suitable guidance approach for FMBH, which is more cost-effective than MRI. However, no experimental validation based on a realized FMBH-CTT system has been reported, which greatly hinders the further advancement of this novel approach. METHODS We developed a preclinical system prototype for the FMBH-CTT technique, containing a microwave phased antenna array, a microwave source, an ultrasound transducer array and associated data acquisition module. RESULTS Experimental results employing homogeneous and inhomogeneous breast-mimicking phantoms demonstrate that the CTT technique can offer reliable guidance for the entire process of the FMBH. In addition, small phase noises do not deteriorate the overall performance of the system prototype. CONCLUSION The realized preclinical FMBH-CTT system prototype is capable for noninvasive, accurate and low-side-effect breast tumor treatment with effective guidance. SIGNIFICANCE The experimentally validated FMBH-CTT system prototype provides a feasible paradigm for CTT guided FMBH, establishes a practical platform for future improvement of this technique, and paves the way for potential clinical translation.

Abstract
Bladder cancer is a significant public health concern and social burden due to its high recurrence risk. Intravesical drug instillation is the primary therapy for bladder cancer to prevent recurrence. However, the intravesical drug therapeutic effect is limited by bladder penetrating barriers. The inadequate intravesical treatment might cause the low drug concentration in lesions, resulting in a high recurrence/progression rate of bladder cancer. Many strategies to get drugs across bladder penetrating barriers have been developed to improve intravesical treatment, including physical and chemical methods. This review summarizes the classical and updated literature and presents insights into great therapeutic potential strategies to overcome bladder penetrating barriers for improving the intravesical treatment of bladder cancer.

Objective: To compare the efficacy and safety of hyperthermic intravesical chemotherapy (HIVEC) and intravesical chemotherapy (IVEC) in patients with intermediate and high risk nonmuscle-invasive bladder cancer (NMIBC) after transurethral resection. Methods: We included 560 patients diagnosed with primary or recurrent NMIBC between April 2009 and December 2015 at 1 of 6 tertiary centers. We matched 364 intermediate or high risk cases and divided them into 2 groups: the HIVEC+IVEC group [chemohyperthermia (CHT) composed of 3 consecutive sessions followed by intravesical instillation without hyperthermia] and the IVEC group (intravesical instillation without hyperthermia). The data were recorded in the database. The primary endpoint was 2-year recurrence-free survival (RFS) in all NMIBC patients (n = 364), whereas the secondary endpoints were the assessment of radical cystectomy (RC) and 5-year overall survival (OS). Results: There was a significant difference in the 2-year RFS between the two groups in all patients (n = 364; HIVEC+IVEC: 82.42% vs. IVEC: 74.18%, P = 0.038). Compared with the IVEC group, the HIVEC+IVEC group had a lower incidence of RC (P = 0.0274). However, the 5-year OS was the same between the 2 groups (P = 0.1434). Adverse events (AEs) occurred in 32.7% of all patients, but none of the events was serious (grades 3–4). No difference in the incidence or severity of AEs between each treatment modality was observed. Conclusions: This retrospective study showed that HIVEC+IVEC had a higher 2-year RFS and a lower incidence of RC than IVEC therapy in intermediate and high risk NMIBC patients. Both treatments were well-tolerated in a similar manner.

Abstract
BACKGROUND: Nearly 70% of all new cases of bladder cancer are non-muscle invasive disease, the treatment for which includes transurethral resection followed by intravesical therapy. Unfortunately, recurrence rates approach 50% in part due to poor intravesical drug delivery. Hyperthermia is frequently used as an adjunct to intravesical chemotherapy to improve drug delivery and response to treatment. OBJECTIVE: To assess the solubility profile of intravesical chemotherapies under varying conditions of pH and temperature. METHODS: Using microplate laser nephelometry we measured the solubility of three intravesical chemotherapy agents (mitomycin C, gemcitabine, and cisplatin) at varying physical conditions. Drugs were assessed at room temperature (23°C), body temperature (37°C), and 43°C, the temperature used for hyperthermic intravesical treatments. To account for variations in urine pH, solubility was also investigated at pH 4.00, 6.00, and 8.00. RESULTS: Heat incrementally increased the solubility of all three drugs studied. Conversely, pH largely did not impact solubility aside for gemcitabine which showed slightly reduced solubility at pH 8.00 versus 6.00 or 4.00. Mitomycin C at the commonly used 2.0 mg/mL was insoluble at room temperature, but soluble at both 37 and 43°C. CONCLUSIONS: Hyperthermia as an adjunct to intravesical treatment would improve drug solubility, and likely drug delivery as some current regimens are insoluble without heat. Improvements in solubility also allow for testing of alternative administration regimens to improve drug delivery or tolerability. Further studies are needed to confirm that improvements in solubility result in increased drug delivery.

Abstract
Objective To report the magnitude, the financial and the economic impact of Bacillus Calmette-Guérin (BCG) shortage in our institute and transfer of non-muscle invasive bladder cancer (NMIBC) patients to higher centers to receive the treatment. Methods This is a retrospective study, between January 2015 and December 2017, the cases of NMIBC diagnosed at Aseer Central Hospital, Abha, Saudi Arabia were studied. Demographic features, clinical presentations, histopathological features, and the BCG therapy shortage and its economic impact were addressed. Results Over a three years study review of 62 urothelial bladder cancer, NMIBC was diagnosed in 55 (89%) patients. Forty-three (78%) patients were males and 12 (22%) patients were females. The mean age ± standard deviation (SD) (range) in this cohort was 59 ± 12 years (38-87). Gross hematuria was the main presentation in 51 (92%) patients of this cohort. Dysuria and other lower urinary tract symptoms were the presentations in 18 (32%) patients. Smoking history was positive in 33 (60%) patients and the rest 22 (40%) patients denied any form of tobacco consumptions. The BCG eligible were 46 (84%) patients of all NMIBC patients in this study. Twenty-seven (59%) patients of them received BCG in our institute. The rest 19 (41%) patients were opted to be transferred to a higher medical center to receive the BCG because of the BCG shortage in our center. The financial cost of traveling to receive the six-weeks induction BCG therapy was on average of 7200 Saudi riyals (1.745 €) for every patient. Conclusions The BCG shortage in our institute is almost approaching half of eligible BCG cases. This has had an economic impact on the health budget. Such health catastrophe could be mitigated with proper health plans of a provision of the BCG to all tertiary care centers. Alternative therapies for such cases should be considered in cases of global BCG shortage.

Abstract
INTRODUCTION Many patients with non-muscle-invasive bladder cancer (NMIBC) failed intravesical BCG therapy. Currently, radical cystectomy is the recommended standard of care for those patients. There is unfortunately no effective other second-line therapy recommended. AREAS COVERED In this review, we present the topics of BCG unresponsive NMIBC; definition, prognosis, and further treatment options: immunotherapy, intravesical chemotherapy, gene therapy, and targeted individualized therapy. EXPERT OPINION There are major challenges of the management of NMIBC who failed BCG therapy as many patients refuse or are unfit for radical cystectomy. Multiple new modalities currently under investigation in ongoing clinical trials to better treat this category of patients. Immunotherapy, especially PD-1/PD-L1 inhibitors, offers exciting and potentially effective strategies for the treatment of BCG unresponsive NMIBC. As the data expands, it is sure that soon there will be established new guidelines for NMIBC.

Abstract
BACKGROUND Hyperthermia (heating to 43 °C) activates the innate immune system and improves bladder cancer chemosensitivity. OBJECTIVE To evaluate the tissue penetration and safety of convective hyperthermia combined with intravesical mitomycin C (MMC) pharmacokinetics in live porcine bladder models using the Combat bladder recirculation system (BRS). METHODS Forty 60 kg-female swine were anesthetized and catheterized with a 3-way, 16 F catheter. The Combat device was used to heat the bladders to a target temperature of 43 °C with recirculating intravesical MMC at doses of 40, 80, and 120 mg. Dwell-heat time varied from 30-180 min. Rapid necropsy with immediate flash freezing of tissues, blood and urine occurred. MMC concentrations were measured by liquid chromatography tandem-mass spectrometry. RESULTS The Combat BRS system was able to achieve target range temperature (42-44 °C) in 12 mins, and this temperature was maintained as long as the device was running. Two factors increased tissue penetration of MMC in the bladder: drug concentration, and the presence of heat. In the hyperthermia arm, MMC penetration saturated at 80 mg, suggesting that with heating, drug absorption may saturate and not require higher doses to achieve the maximal biological effect. Convective hyperthermia did not increase the MMC concentration in the liver, heart, kidney, spleen, lung, and lymph node tissue even at the 120 mg dose. CONCLUSIONS Convective bladder hyperthermia using the Combat BRS device is safe and the temperature can be maintained at 43 °C. Hyperthermia therapy may increase MMC penetration into the bladder wall but does not result in an increase of MMC levels in other organs.

A moderate thermal dose is sufficient for effective free and TSL based thermochemotherapy. Adv Drug Deliv Rev 2020; 163-164:145-156.

Abstract
Hyperthermia, i.e. heating the tumor to a temperature of 40-43 °C is considered by many a valuable treatment to sensitize tumor cells to radiotherapy and chemotherapy. In recent randomized trials the great potential of adding hyperthermia to chemotherapy was demonstrated for treatment of high risk soft tissue sarcoma: +11.4% 5 yrs. overall survival (OS) and for ovarian cancer with peritoneal involvement nearly +12 months OS gain. As a result interest in combining chemotherapy with hyperthermia, i.e. thermochemotherapy, is growing. Extensive biological research has revealed that hyperthermia causes multiple effects, from direct cell kill to improved oxygenation, whereby each effect has a specific temperature range. Thermal sensitization of the tumor cell for chemotherapy occurs for many drugs at temperatures ranging from 40 to 42 °C with little additional increase of sensitization at higher temperatures. Increasing perfusion/oxygenation and increased extravasation are two other important hyperthermia induced mechanisms. The combination of free drug and hyperthermia has not been found to increase tumor drug concentration. Hence, enhanced effectiveness of free drug will depend on the thermal sensitization of the tumor cells for the applied drug. In contrast to free drugs, experimental animal studies combining hyperthermia and thermo-sensitive liposomal (TSL) drugs delivery have demonstrated to result in a substantial increase of the drug concentration in the tumor. For TSL based chemotherapy, hyperthermia is critical to both increase perfusion and extravasation as well as to trigger TSL drug release, whereby the temperature controlled induction of a local high drug concentration in a highly permeable vessel is driving the enhanced drug uptake in the tumor. Increased drug concentrations up to 26 times have been reported in rodents. Good control of the tissue temperature is required to keep temperatures below 43 °C to prevent vascular stasis. Further, careful timing of the drug application relative to the start of heating is required to benefit optimal from the combined treatment. From the available experimental data it follows that irrespective whether chemotherapy is applied as free drug or using a thermal sensitive liposomal carrier, the optimal thermal dose for thermochemotherapy should be 40-42 °C for 30-60 min, i.e. equivalent to a CEM43 of 1-15 min. Timing is critical: most free drug should be applied simultaneous with heating, whereas TSL drugs should be applied 20-30 min after the start of hyperthermia.

Abstract
BACKGROUND: Bacillus Calmette-Guerin (BCG) is the recommended therapy for high and intermediate risk non-muscle invasive bladder cancer (NMIBC), but treatment failure is common. While a radical cystectomy is recommended after BCG failure, some patients desire bladder preservation and others are poor surgical candidates. Salvage chemotherapy treatments may be offered to this subgroup of patients. OBJECTIVE: To assess if combination, hyperthermic Gemcitabine and Docetaxel chemotherapy (GEM/DOCE) is a safe and effective salvage option for treating NMIBC. METHODS: Sixty patients who received our GEM/DOCE protocol between 2007–2017 were identified (51 BCG failures, 9 BCG naïve). This study measured overall treatment success, defined as no recurrence, progression, cystectomy, nor death due to bladder cancer. Kaplan-Meier curves were used to ascertain probability of treatment success. The log-rank test was used to identify factors associated with treatment success. RESULTS: Sixty patients received treatment with a median follow-up of 14.9 months. All patients completed the induction course with no significant adverse effects. Overall treatment success was 83% at first surveillance, 69% at 1 year, and 55% at 2 years in the entire cohort, and 90% at first surveillance, 74% at 1 year, and 56% at 2 years in the BCG-failure patients. All-cause and bladder-cancer-specific survival were both 97.9% at 1 year, 85.9% and 94.6% respectively at 2 years. Three patients underwent cystectomy at a median of 10.2 months, two of these were secondary to recurrences. Three patients had progression of their disease. CONCLUSIONS: Hyperthermic GEM/DOCE seems to be a well-tolerated salvage regimen that demonstrates a reasonable efficacy and warrants further investigation.

Abstract
Background: Non-muscle invasive bladder cancer accounts for nearly 80% of newly diagnosed bladder cancer cases, which often recur and progress. This meta-analysis was evaluated by the adverse events and recurrence rate of thermal intravesical chemotherapy vs. normal temperature intravesical chemotherapy in the treatment of non-muscle invasive bladder cancer. Methods: A systematic review and cumulative analysis of studies reporting adverse events and recurrence rate of thermal intravesical chemotherapy vs. normal temperature intravesical chemotherapy was performed through a comprehensive search of Pubmed, Embase, Cochranelibrary.com, CNKI, Wanfang Med Online database and VIP database. All analyses were performed using the Revman manager 5. Result: Twelve studies (11 randomized controlled trials and 1 retrospective study) including 888 patients, 445 in the thermal intravesical chemotherapy group, and 443 in the normal temperature intravesical chemotherapy group, met the eligibility criteria. Patients in the thermal intravesical chemotherapy group had a lower risk of disease recurrence than those who had normal temperature intravesical chemotherapy (24 months follow-up group: RR = 0.30, 95% CI: 0.21-0.43, P < 0.00001, I 2 = 0%; 36 months follow-up group: RR = 0.27, 95% CI: 0.14-0.54, P = 0.0002, I 2 = 0%) while no significant difference in adverse events rate (RR = 0.89, 95% CI = 0.53-1.52; P = 0.67, I 2 = 78%). Conclusions: When compared with normal temperature intravesical chemotherapy, thermal intravesical chemotherapy can reduce the recurrence rate without increasing incidence of adverse events in patients with non-muscle invasive bladder cancer.

Abstract
Management of patients with bacillus Calmette-Guérin (BCG)-unresponsive, high-risk, non-muscle-invasive bladder cancer (NMIBC) presents a formidable clinical challenge that requires urologists to weigh the competing risks of progression during further intravesical therapy vs. the morbidity of radical cystectomy. The prognosis of high-risk NMIBC recurring after BCG depends on the adequacy of prior BCG, timing of recurrence, and tumor histology. The standard of care is currently radical cystectomy, as effective salvage intravesical therapy has not been established. The development of bladder-sparing treatments has been hampered to date by inconsistent definitions of BCG failure and difficulties in identifying appropriate control treatments in clinical trials. Despite these limitations, the spectrum of salvage therapy is expanding to include enhanced intravesical chemo-, gene, and immuno-therapies. In this review, we provide an overview of these emerging agents in the context of our current understanding of BCG failure and the unique considerations for clinical trial design in this disease state.

Abstract
Objectives: To investigate whether warm sterile water enhances the cytocidal effect of hypotonic shock on bladder cancer cells that show resistance to sterile water.Methods: Four bladder cancer cell lines of varying grades (T24, RT4, J82, and RT112) were exposed to sterile water, and morphological changes were closely observed under microscopy. Changes in cell membrane integrity and cell viability after water exposure were measured to determine the effects of water-induced hypotonic shock. Additionally, the effects of warm sterile water were analyzed.Results: T24, RT4, and J82 cells started swelling immediately upon exposure to water, followed by rupture within five minutes. RT112 cells demonstrated limited hypotonic swelling with significantly less cell rupture after 10 min. The percentages of viable cells at 10 min were 1.6 ± 0.8%, 3.5 ± 3.5%, 5.0 ± 3.2%, and 22.0 ± 10.3% for T24, RT4, J82, and RT112, respectively. The percentage of viable cells with 48 °C sterile water at one minute was 0% for RT112 cells.Conclusions: These findings support the efficacy of sterile water against bladder cancer cells and reveal that warm sterile water enhances the cytocidal effects of hypotonic shock, potentially avoiding the need for radical surgery.

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
Apaziquone is an interesting drug for intravesical use in patients with nonmuscle invasive bladder cancer; however, more research is needed to prove its actual benefit. Although the apaziquone trials demonstrate the potential of this new drug, the singular phase 3 trials did not reach their primary endpoint. To date, no new trials are recruiting, so the development of apaziquone seems to have stopped.

Abstract
Non-muscle-invasive bladder cancer (NMIBC), the most prevalent type of bladder cancer, accounts for ~75% of bladder cancer diagnoses. This disease has a 50% risk of recurrence and 20% risk of progression within 5 years, despite the use of intravesical adjuvant treatments (such as BCG or mitomycin C) that are recommended by clinical guidelines. Intravesical device-assisted therapies, such as radiofrequency-induced thermochemotherapeutic effect (RITE), conductive hyperthermic chemotherapy, and electromotive drug administration (EMDA), have shown promising efficacy. These device-assisted treatments are an attractive alternative to BCG, as issues with supply have been a problem in some countries. RITE might be an effective treatment option for some patients who have experienced BCG failure and are not candidates for radical cystectomy. Data from trials using EMDA suggest that it is effective in high-risk disease but requires further validation, and results of randomized trials are eagerly awaited for conductive hyperthermic chemotherapy. Considerable heterogeneity in patient cohorts, treatment sessions, use of maintenance regimens, and single-arm study design makes it difficult to draw solid conclusions, although randomized controlled trials have been reported for RITE and EMDA.

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
Introduction: The current first line therapy for high grade (HG) non-muscle invasive bladder cancer (NMIBC) is intravesical Bacillus Calmette-Guerin (BCG). Patients who recur or progress despite BCG are recommended to undergo radical cystectomy or participate in clinical trials. There is an urgent need for alternative therapies in the BCG-unresponsive NMIBC realm. Areas covered: We queried clinicaltrials.gov and pubmed.gov for current and recently completed early clinical trials pertaining to investigational agents used for the treatment of BCG-unresponsive NMIBC. These included intravesical chemotherapy, immunotherapy, vaccines, gene therapy, viruses, and agents used with novel drug delivery methods. In this article, we discuss the treatment guidelines for non-muscle invasive bladder cancer and therapeutic approaches under investigation in clinical trials. Expert opinion: The FDA is currently allowing single-arm studies as a pathway for approval in BCG-refractory patients with CIS. Although many agents are currently undergoing testing, none have been approved since Valrubicin. Hopefully, we will identify therapies sufficiently effective and durable to achieve FDA approval. Other considerations in this realm include the use of biomarkers in NMIBC to identify patients who will most likely respond to specific interventions. In addition, as systemic agents such as checkpoint inhibitors, are studied further, a multidisciplinary approach may be needed to treat this subset of patients.

Abstract
Non-muscle invasive bladder cancer (NMIBC) is a challenging disease, with a high risk of recurrence and even progression to muscle invasive disease. The present standard treatment is suboptimal, and consists of a complete transurethral resection of the visible bladder tumour(s), followed by prophylactic intravesical instillations mitomycin-C (MMC) or bacillus Calmette-Guérin (BCG). In search for higher efficacy, several adjuvant device-assisted intravesical therapies are developed. Chemohyperthermia may be based on microwave-/radiofrequency-induced (RF) hyperthermia systems, for which most evidence exists, or on hyperthermic intravesical chemotherapy, which is applied by conductive or loco-regional heating systems. RF-induced CHT has shown superiority over MMC alone, and in one prospective study superiority over BCG in per-protocol analysis, which has led to the ‘weak’ recommendation in the EAU guidelines to consider RF-based CHT as a bladder preservation strategy in patients with BCG-refractory tumours, who are not candidates for radical cystectomy due to comorbidities. Prospective studies on hyperthermic intravesical chemotherapy for patients with intermediate-risk NMIBC are awaited next year. The combination of electromotive drug administration (EMDA) with MMC has shown superiority over MMC as well, and seems promising when combined with BCG in sequential treatment. Photodynamic therapy should still be considered experimental, in which a study with the intravenous photosensitizer Radachlorin® has shown promising results.

Ex vivo assays to predict enhanced chemosensitization by hyperthermia in urothelial cancer of the bladder. PLoS One 2018; 13:e0209101. [PMID: 30550547 PMCID: PMC6294360 DOI: 10.1371/journal.pone.0209101] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2018] [Accepted: 11/28/2018] [Indexed: 01/03/2023] Open
Abstract
INTRODUCTION Bladder cancer (urothelial carcinoma) is a common malignancy characterized by high recurrence rates and intense clinical follow-up, indicating the necessity for more effective therapies. Current treatment regimens include intra-vesical administration of mitomycin C (MMC) for non-muscle invasive disease and systemic cisplatin for muscle-invasive or metastatic disease. Hyperthermia, heating a tumor to 40-44°C, enhances the efficacy of these chemotherapeutics by various modes of action, one of which is inhibition of DNA repair via homologous recombination. Here, we explore whether ex vivo assays on freshly obtained bladder tumors can be applied to predict the response towards hyperthermia. MATERIAL AND METHODS The cytochrome C release assay (apoptosis) and the RAD51 focus formation assay (DNA repair) were first established in the bladder cancer cell lines RT112 and T24 as measurements for hyperthermia efficiency, and subsequently tested in freshly obtained bladder tumors (n = 59). RESULTS Hyperthermia significantly increased the fraction of apoptotic cells after cisplatin or MMC treatment in both RT112 and T24 cells and in most of the bladder tumors (8/10). The RAD51 focus formation assay detected both morphological and numerical changes of RAD51 foci upon hyperthermia in the RT112 and T24 cell lines. In 64% of 37 analyzed primary bladder tumor samples, hyperthermia induced similar morphological changes in RAD51 foci. CONCLUSION The cytochrome C assay and the RAD51 focus formation assay are both feasible on freshly obtained bladder tumors, and could serve to predict the efficacy of hyperthermia together with cytotoxic agents, such as MMC or cisplatin.

Abstract
INTRODUCTION Intravesical therapy has been an important aspect of the management of non-muscle invasive bladder cancer (NMIBC) for 40 years. Bacillus Calmette-Guerin (BCG) is considered standard of care for intermediate and high-grade non-invasive disease, yet understanding the nuances of subsequent intravesical therapy is important for any provider managing bladder cancer. Herein, we review the literature and describe optimal use of intravesical therapies for NMIBC. METHODS A comprehensive search of the medical literature was performed and highlighted in this review of intravesical therapy for NMIBC. RESULTS Post-resection intravesical Mitomycin C therapy for low-risk disease remains an important component of care, and gemcitabine now has level-one evidence demonstrating efficacy in this setting but is not yet a guideline recommendation. BCG intravesical therapy remains the most effective therapy preventing recurrence and progression of intermediate and high-risk NMIBC. Adequately characterizing BCG-failure is critical in determining the next step in management which includes radical cystectomy, additional intravesical immunotherapy, chemotherapy with intravesical gemcitabine ± docetaxel and clinical trials. CONCLUSIONS Intravesical therapy remains the mainstay of treatment for NMIBC and bladder preservation. Intravesical induction BCG followed by maintenance therapy remains standard of care for intermediate and high-risk patients. Detailing the timing and characteristics of recurrence after intravesical therapy is crucial in determining subsequent treatment recommendations. Current clinical trials focus on systemic immunotherapy and enhancing the intravesical immune response by augmenting the delivery mechanism.

Abstract
Objective: To examine the effect of intravesical radiofrequency-induced chemohyperthermia (RF-CHT) in carcinoma in-situ (CIS) patients overall and split according to previously received therapy. Methods: CIS patients that underwent an induction and maintenance phase of≥6 RF-CHT instillations, and had either pathology or cystoscopy plus cytology available at 6 months of follow-up were retrospectively included. Complete response (CR), recurrences, cystectomy-free rate, overall survival (OS), and adverse events were evaluated. Analysis was performed for overall, bacillus Calmette-Guérin (BCG)-unresponsive, other BCG-treated, and treatment naïve patients. Results: Patients (n = 150) had a mean of 17.5, 9.2, or 0 previous BCG instillations in the BCG-unresponsive (n = 50), other BCG-treated (n = 46, missing n = 4), and treatment naïve groups (n = 47, missing n = 3), respectively. After 6 months, a CR of 46.0%, 71.7%, and 83.0% was found (p < 0.001). Subsequent 2-year recurrence rates were 17.4%, 27.3%, and 12.8%, respectively. The overall cystectomy-free rate and OS at mean follow-up (35.8 months) were 78.5% and 78.0%, respectively. These were 71.4% vs. 84.1% vs. 86.7% (cystectomy-free rate, p = 0.006) and 76.0% vs. 69.6% vs. 87.2% (OS, p = 0.06) for BCG-unresponsive vs. other BCG-treated vs. treatment naïve patients. Progression to muscle-invasive disease was seen in 13.3% of patients. Patients stopped induction or maintenance RF-CHT instillations due to adverse events in respectively 13.4% and 17.8%. Conclusions: Intravesical RF-CHT showed good results in both treatment naïve and BCG-treated CIS patients, avoiding the need for cystectomy in 78.5% of cases for at least 3 years with a modest risk of progression. Thus, RF-CHT proves an alternative to cystectomy in selected high-risk patients.

Abstract
Background: Adjuvant intravesical instillations with bacillus Calmette-Guérin (BCG) is the recommended treatment option for patients with intermediate-and high-risk non-muscle invasive bladder cancer (NMIBC). Despite adequate BCG treatment, a large proportion of patients experience a recurrence. Although radical cystectomy is the gold standard for BCG unresponsive NMIBC, some patients are unfit or unwilling to consider this option. Objective: To assess the effectiveness of Hyperthermic IntraVEsical Chemotherapy (HIVEC®) in BCG unresponsive NMIBC patients. Methods: A post-hoc analysis was conducted of prospectively included intermediate-and high-risk NMIBC patients who were planned to receive HIVEC® treatment between October 2014 and November 2017. For the present analysis, only patients who met the BCG unresponsive definition were included. Patients were followed by cystoscopy and cytology every 3 months and a CT-urography scan yearly. The primary outcome was the disease-free survival (DFS). The Common Terminology Criteria for Adverse Events (CTCAE) was used to assess side-effects. Results: The study population consisted of 55 BCG unresponsive NMIBC patients of whom 52 underwent≥5 HIVEC® treatments. The median age and follow-up were 73 years and 14.0 months (IQR 7.6 – 24.6). The median DFS was 17.7 months (SE 6.72) and progression occurred in four patients. The 1-year cumulative incidence rate of disease recurrence/progression was 53%. Two patients experienced severe side-effects (CTCAE≥3). Conclusions: HIVEC® seems a valid treatment option for BCG unresponsive NMIBC patients. We report a median DFS of 17.7 months (SE 6.72), potentially avoiding or postponing the need for radical surgery in a proportion of these patients.

Abstract
The Fourth Annual Albert Institute Bladder Cancer Care and Research Symposium was held from September 14th–16th in Houston, Texas. The symposium covered a range of topics relevant to bladder cancer, including basic science aspects of immunology and immunotherapy that inform clinical management; intravesical therapy for non-muscle invasive disease; understanding the nuances of carcinoma in situ; and optimizing patient care and outcomes following therapy. The moving landscape of bladder cancer from an industry perspective was also discussed. In the following sections we discuss intrinsic and extrinsic factors, including the immune microenvironment and sex bias, in the context of bladder cancer; how these influence tumor development, progression, and treatment strategies; and how the interpretation of immune features in relation to molecular subtypes informs both treatment decisions and response. We conclude with a summary of key points that will need to be addressed to ensure best use of new knowledge in this area for improved clinical management of patients with bladder cancer.

Abstract
INTRODUCTION Several techniques can be used to treat intravesical chemohyperthermia (ChHT). We compared radiofrequency-induced hyperthermia (RF-HT) with conductive hyperthermia (C-HT) for their ability to induce bladder wall temperatures of >40.5 °C, the target temperature for ChHT. MATERIALS AND METHODS Fresh porcine bladders (n = 12) were placed in a temperature-controlled saline bath to simulate body temperature and circulation. HT was induced with RF-HT (43 °C) or C-HT (inflow temperature 44 and 46 °C) using a custom-made device. In two additional bladders, we varied intravesical solution and volume. Temperatures were recorded with a three-way catheter containing three mucosal and two urethral thermocouples (TCs) and a 915 MHz RF antenna, and with external TCs in the bladder wall at three different levels and three different locations. RESULTS Target temperature (40.5 °C) was reached in the submucosa at all locations by both techniques. In the detrusor, target temperature was reached by RF-HT at the bladder neck and side wall. C-HT46 reached significantly higher submucosal temperatures at the side wall. The bladder dome seemed best heated by C-HT, although a high inflow temperature (46 vs. 44 °C) was required (ns). Intravesical saline resulted in higher temperatures than sterile water for RF-HT. A volume of 100 mL resulted in higher bladder dome temperatures for RF-HT, and higher bladder neck with lower dome temperatures for C-HT. CONCLUSION Our results indicate a slightly superior heating capacity for RF-HT compared to C-HT, whereas for the bladder dome, the reverse seems true. Comparative studies are warranted to evaluate whether HT efficacy differs between both techniques, with emphasis on tumor location.

Radiofrequency-induced Thermo-chemotherapy Effect Versus a Second Course of Bacillus Calmette-Guérin or Institutional Standard in Patients with Recurrence of Non-muscle-invasive Bladder Cancer Following Induction or Maintenance Bacillus Calmette-Guérin Therapy (HYMN): A Phase III, Open-label, Randomised Controlled Trial. Eur Urol 2018; 75:63-71. [PMID: 30274699 DOI: 10.1016/j.eururo.2018.09.005] [Citation(s) in RCA: 79] [Impact Index Per Article: 13.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2018] [Accepted: 09/04/2018] [Indexed: 11/19/2022]
Abstract
BACKGROUND There is no effective intravesical second-line therapy for non-muscle-invasive bladder cancer (NMIBC) when bacillus Calmette-Guérin (BCG) fails. OBJECTIVE To compare disease-free survival time (DFS) between radiofrequency-induced thermo-chemotherapy effect (RITE) and institutional standard second-line therapy (control) in NMIBC patients with recurrence following induction/maintenance BCG. DESIGN, SETTINGS, AND PARTICIPANTS Open-label, phase III randomised controlled trial accrued across 14 centres between May 2010 and July 2013 (HYMN [ClinicalTrials.gov: NCT01094964]). INTERVENTION Patients were randomly assigned (1:1) to RITE (60min, 40mg mitomycin-C, 42±2°C) or control following stratification for carcinoma in situ (CIS) status (present/absent), therapy history (failure of previous induction/maintenance BCG), and treatment centre. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Primary outcome measures were DFS and complete response (CR) at 3 mo for the CIS at randomisation subgroup. Analysis was based on intention-to-treat. RESULTS AND LIMITATIONS A total of 104 patients were randomised (48 RITE: 56 control). Median follow-up for the 31 patients without a DFS event was 36 mo. There was no significant difference in DFS between treatment arms (hazard ratio [HR] 1.33, 95% confidence interval [CI] 0.84-2.10, p=0.23) or in 3-mo CR rate in CIS patients (n=71; RITE: 30% vs control: 47%, p=0.15). There was no significant difference in DFS between treatment arms in non-CIS patients (n=33; RITE: 53% vs control: 24% at 24 mo, HR 0.50, 95% CI 0.22-1.17, p=0.11). DFS was significantly lower in RITE than in control in CIS with/without papillary patients (n=71; HR 2.06, 95% CI 1.17-3.62, p=0.01; treatment-subgroup interaction p=0.007). Disease progression was observed in four patients in each treatment arm. Adverse events and health-related quality of life between treatment arms were comparable. CONCLUSIONS DFS was similar between RITE and control. RITE may be a second-line therapy for non-CIS recurrence following BCG failure; however, confirmatory trials are needed. RITE patients with CIS with/without papillary had lower DFS than control. HYMN highlights the importance of the control arm when evaluating novel therapies. PATIENT SUMMARY This study did not show a difference in bladder cancer outcomes between microwave-heated chemotherapy and standard of care treatment. Papillary bladder lesions may benefit from microwave-heated chemotherapy treatment; however, more research is needed. Both treatments are similarly well tolerated.

Abstract
PURPOSE To provide a summary of the Third International Consultation on Bladder Cancer recommendations for the management of non-muscle invasive bladder cancer (NMIBC). METHODS A detailed review of the literature was performed focusing on original articles for the management of NMIBC. An international committee assessed and graded the articles based on the Oxford Centre for Evidence-based Medicine system. The entire spectrum of NMIBC was covered such as prognostic factors of recurrence and progression, risk stratification, staging, management of positive urine cytology with negative white light cystoscopy, indications of bladder and prostatic urethral biopsies, management of Ta low grade (LG) and high risk tumors (Ta high grade [HG], T1, carcinoma in situ [CIS]), impact of BCG strain and host on outcomes, management of complications of intravesical therapy, role of alternative therapies, indications for early cystectomy, surveillance strategies, and new treatments. The working group provides several recommendations on the management of NMIBC. RESULTS Recommendations were summarized with regard to staging; management of primary and recurrent LG Ta and high risk disease, positive urine cytology with negative white light cystoscopy and prostatic urethral involvement; indications for timely cystectomy; and surveillance strategies. CONCLUSION NMIBC remains a common and challenging malignancy to manage. Accurate staging, grading, and risk stratification are critical determinants of the management and outcomes of these patients. Current tools for risk stratification are limited but informative, and should be used in clinical practice when determining diagnosis, surveillance, and treatment of NMIBC.

Abstract
BACKGROUND Mitomycin C (MMC) is an antitumor agent that is often administered intravesically to treat bladder cancer. Pharmacologically optimized studies have suggested varying methods to optimize delivery, with drug concentration and solution volume being the main drivers. However, these MMC concentrations (e.g. 2.0 mg/mL) supersede its solubility threshold, raising major concerns of inferior drug delivery. OBJECTIVE In this study, we seek to confirm that the pharmacologically optimized MMC concentrations are achievable in clinical practice through careful modifications of the solution preparation methods. METHODS MMC admixtures (1.0 and 2.0 mg/mL) were prepared in normal saline using conventional and alternative compounding methods. Conventional methodology resulted in poorly soluble solutions, with many visible particulates and crystallates. However, special compounding methods, which included incubation of solutions at 50 °C for 50 min followed by storage at 37 °C, were sufficient to solubilize drug. Chemical degradation of MMC solutions was determined over 6 h using high-performance liquid chromatography (HPLC) analytics, while physical stability was tested in parallel. RESULTS Immediately following the 50 min incubation, both MMC solutions exhibited approximately 5-7% drug degradation. Based on the measured concentrations and linear regression of degradation plots, additional storage of these solutions at 37 °C for 5 h retained chemical stability criterion (< 10% overall drug loss). No physical changes were observed in any solutions at any test time points. CONCLUSION We recommend that the described alternative preparation methods may improve intravesicular delivery of MMC in this urological setting, and advise that clinicians employing these changes should closely monitor patients for MMC toxicities and pharmacodynamics (change in clinical outcomes) that result from the potential enhancement of MMC exposure in the bladder.
