Comparison of hyperthermic intravesical chemotherapy and Bacillus Calmette-Guerin therapy in high-risk non-muscle invasive bladder cancer: a matched-pair analysis. Int Urol Nephrol 2024; 56:957-963. [PMID: 37880493 DOI: 10.1007/s11255-023-03849-x] [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: 08/13/2023] [Accepted: 10/06/2023] [Indexed: 10/27/2023]
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
Bladder tumors have a high mutational burden and tend to be responsive to immune therapies; however, response rates remain modest. To date, immunotherapy in bladder cancer has largely focused on enhancing T-cell immune responses in the bladder tumor microenvironment. It is anticipated that other immune cells, including innate lymphoid cells (ILC), which play an important role in bladder oncogenesis and tumor suppression, could be targeted to improve response to existing therapies. ILCs are classified into five groups: natural killer cells, ILC1s, ILC2s, ILC3s, and lymphoid tissue inducer cells. ILCs are pleiotropic and play dual and sometimes paradoxical roles in cancer development and progression. Here, a comprehensive discussion of the current knowledge and recent advancements in understanding the role of ILCs in bladder cancer is provided. We discuss the multifaceted roles that ILCs play in bladder immune surveillance, tumor protection, and immunopathology of bladder cancer. This review provides a rationale for targeting ILCs in bladder cancer, which is relevant for other solid tumors.

Abstract
INTRODUCTION Radical cystectomy remains the standard treatment for intravesical Bacille Calmette-Guerin (BCG) unresponsive non-muscle invasive bladder cancer (NMIBC) because potential bladder-preserving therapies are not well established. Combination of radiotherapy with programmed death-1 (PD-1) antibody may offer an optional bladder preservation treatment for high-risk/extremely high risk NMIBC. Hence, the current study aims to investigate the safety and efficacy of short-course radiotherapy (5×5 Gy) and toripalimab (PD-1 antibody) as a novel bladder sparing treatment in this population. METHODS AND ANALYSIS HOPE-04 is an open-label, single-arm, phase II study, designed to evaluate the safety and efficacy of short-course radiotherapy and toripalimab in patients with high-risk/extremely high risk NMIBC. Fifty-five patients with pathological and imaging diagnosed NMIBC with or without BCG treatment will be recruited. Radiotherapy of 5×5 Gy will be given to the whole bladder followed by a focal tumour bed boost and concomitant administration of toripalimab of 240 mg intravenous infusion every 21 days for 12 cycles (about 1 year). The primary endpoints are disease-free survival and safety. The secondary endpoint is overall survival. Additional indicators include implementation rate of salvage surgery and quality of life. ETHICS AND DISSEMINATION This trial has been approved by the Ethics Committee of West China Hospital, Sichuan University. Trial findings will be disseminated via peer reviewed journals and conference presentations. TRIAL REGISTRATION NUMBER Chinese Ethics Committee of Registering Clinical Trials (ChiCTR2200059970).

Abstract
OBJECTIVES Examine the understanding of terminologies and management patterns of bacillus Calmette-Guérin (BCG)-unresponsive nonmuscle invasive bladder cancer (NMIBC) in six territories in Asia-Pacific. METHODS This study involved two phases: (1) a survey with 32 urologists and 7 medical oncologists (MOs) and (2) a factorial experiment and in-depth interviews with 23 urologists and 2 MOs. All clinicians had ≥8 years' experience managing NMIBC patients in Australia, Hong Kong, Japan, South Korea, Singapore, and Taiwan. Data from Phase 1 were summarized using descriptive statistics; content and thematic analyses applied in Phase 2. RESULTS In phase 1, 35% of clinicians defined BCG-unresponsive as BCG-refractory, -relapse and -resistant, 6% defined it as BCG-refractory and -relapse; 22% classified BCG-failure as BCG-refractory, -relapse, -resistant, and when muscle-invasive bladder cancer is detected. If eligible and willing, 50% (interquartile range [IQR], 50%-80%) of BCG-unresponsive patients would undergo radical cystectomy (RC), and 50% (IQR 20%-50%) of RC-eligible patients would receive bladder-sparing treatment or surveillance. In phase 2, we found that 32%, 88%, and 48% of clinicians, respectively, used "BCG-unresponsive," "BCG-refractory," and "BCG-relapse" in clinical practice but with no consistent interpretation of the terms. Compared with EAU definitions, 8%-60% of clinicians appropriately classified 9 tumor types that are persistent or recurrent after adequate BCG. Fifty percent of clinicians mentioned a lack of bladder-preserving treatment that outperforms RC in quality of life as a reason to retreat BCG-unresponsive patients with BCG. CONCLUSIONS Our study revealed varied understanding and application of BCG-unresponsive terminologies in practice. There is a need for a uniform and simple definition of BCG-unresponsive disease in Asia-Pacific.

Abstract
PURPOSE There is a significant unmet need for new and efficacious therapies in urothelial cancer (UC). To provide recommendations on appropriate clinical trial designs across disease settings in UC, the Society for Immunotherapy of Cancer (SITC) and the International Bladder Cancer Group (IBCG) convened a multidisciplinary, international consensus panel. METHODS Through open communication and scientific debate in small- and whole-group settings, surveying, and responses to clinical questionnaires, the consensus panel developed recommendations on optimal definitions of the disease state, end points, trial design, evaluations, sample size calculations, and pathology considerations for definitive studies in low- and intermediate-risk nonmuscle-invasive bladder cancer (NMIBC), high-risk NMIBC, muscle-invasive bladder cancer in the neoadjuvant and adjuvant settings, and metastatic UC. The expert panel also solicited input on the recommendations through presentations and public discussion during an open session at the 2021 Bladder Cancer Advocacy Network (BCAN) Think Tank (held virtually). RESULTS The consensus panel developed a set of stage-specific bladder cancer clinical trial design recommendations, which are summarized in the table that accompanies this text. CONCLUSION These recommendations developed by the SITC-IBCG Bladder Cancer Clinical Trial Design consensus panel will encourage uniformity among studies and facilitate drug development in this disease.

Abstract
OBJECTIVE Among patients diagnosed with non-muscle invasive bladder cancer (NMIBC), those with high risk disease have the greatest risk of recurrence and disease progression. The underutilization of intravesical immunotherapy with Bacillus Calmette-Guérin (BCG) has been a longstanding concern in clinical practice. This study aimed to determine the disparities present in receipt of adjuvant intravesical chemotherapy and immunotherapy in treatment of patients with high grade NMIBC following initial transurethral resection of a bladder tumor (TURBT). METHODS The California Cancer Registry data was used to identify 19,237 patients diagnosed with high grade NMIBC who underwent TURBT. Treatment variables include re-TURBT, re-TURBT and intravesical chemotherapy (IVC) and/or BCG. Independent variables include age, sex, race/ethnicity, neighborhood socioeconomic status (nSES), primary insurance payer and marital status at diagnosis. Multiple logistic regression and multinomial regression models were used to examine variation in the treatments received following TURBT. RESULTS The proportion of patients receiving TURBT followed by BCG was similar across all racial and ethnic groups (28%-32%). BCG therapy was higher in patients belonging to the highest nSES quintile (37% for highest vs. 23%-26% for the 2 lowest quintiles). In multiple variable analyses, receipt of any intravesical therapy (IVT) was influenced by nSES, age, marital status, race/ethnicity, and insurance type. Patients in the lowest nSES quintile had a 45% less likelihood of receiving IVT compared to the highest nSES group (OR [95%CI]: 0.55[0.49, 0.61]). Race/ethnicity differences in receipt of any adjuvant therapy were noted in the middle to lowest nSES quintile for Hispanic and Asian/Pacific Islander patients when compared to non-Hispanic White patients. When comparing variation in treatment by insurance type at diagnosis, those with Medicare or other insurance were 24% and 30% less likely to receive BCG after TURBT compared to those with private insurance, (OR [95%CI]: 0.76 [0.70, 0.82] and 0.70[0.62, 0.79]) respectively. CONCLUSION In patients with a diagnosis of high risk NMIBC, disparities in utilization of BCG are seen based on SES, age, and insurance type.

Abstract
OBJECTIVE We demonstrate a new model framework as an innovative approach to more accurately estimate and project prevalence and survival outcomes in oncology. METHODS We developed an oncology simulation model (OSM) framework that offers a customizable, dynamic simulation model to generate population-level, country-specific estimates of prevalence, incidence of patients progressing from earlier stages (progression-based incidence), and survival in oncology. The framework, a continuous dynamic Markov cohort model, was implemented in Microsoft Excel. The simulation runs continuously through a prespecified calendar time range. Time-varying incidence, treatment patterns, treatment rates, and treatment pathways are specified by year to account for guideline-directed changes in standard of care and real-world trends, as well as newly approved clinical treatments. Patient cohorts transition between defined health states, with transitions informed by progression-free survival and overall survival as reported in published literature. RESULTS Model outputs include point prevalence and period prevalence, with options for highly granular prevalence predictions by disease stage, treatment pathway, or time of diagnosis. As a use case, we leveraged the OSM framework to estimate the prevalence of bladder cancer in the United States. CONCLUSION The OSM is a robust model that builds upon existing modeling practices to offer an innovative, transparent approach in estimating prevalence, progression-based incidence, and survival for oncologic conditions. The OSM combines and extends the capabilities of other common health-economic modeling approaches to provide a detailed and comprehensive modeling framework to estimate prevalence in oncology using simulation modeling and to assess the impacts of new treatments on prevalence over time.

Abstract
Human urothelial bladder carcinoma (uBC) is the second most tumor entity of the urogenital tract. As far as possible, therapy for non-muscle invasive uBC takes place as resection of the tumor tissue, followed by intravesical chemotherapy or immunotherapy. Because of the high recurrence rate of uBC, there is a need for improved efficiency in the treatment. In the present in vitro study we have evaluated a new approach to enhance the cytotoxic efficiency of Mitomycin C (MMC), which is commonly used for intravesical treatment of uBC on the relevant urothelial cancer cell line RT112. For that we used quasi-monochromatic blue light (453 ± 10 nm) at its non-toxic dose of 110 J/cm2 as an additive stimulus to enhance the therapeutic efficiency of MMC (10 μg/ml). We found, that blue light exposure of RT112 cells led to a very strong increase in intracellular production of reactive oxygen species (ROS) and to a significant reduction (p < 0.05) of all function parameters of mitochondrial respiration, including basal activity and ATP production. Although not being toxic when used as a single impact, together with MMC blue light strongly enhanced the therapeutic efficiency of MMC in the form of significantly enhanced cytotoxicity via apoptosis and secondary necrosis. Our results clearly show that blue light, most likely due to its ability to increase intracellular ROS production and reduce mitochondrial respiration, increased the cytotoxic efficiency of MMC and therefore might represent an effective, low-side-effect, and success-enhancing therapy option in the local treatment of bladder cancer.

Abstract
PURPOSE Partial cystectomy was investigated as a method of bladder preservation with better disease outcomes than transurethral bladder tumor resection in T1 high-grade bladder cancer patients. Method and materials. The national Surveillance, Epidemiology, and End Results database (SEER) (2004-2015) were used to obtain patients diagnosed with T1 high-grade bladder cancer, and finally, 25263 patients were enrolled in our study. The Kaplan-Meier method with the log-rank test was performed to analyze the outcome of overall survival (OS) and cancer-specific survival (CSS) between patients undergoing partial cystectomy (PC), transurethral resection of bladder tumor (TURBT), or radical cystectomy (RC). Moreover, the propensity score matching (PSM) and multivariable Cox proportional hazard model were also utilized in the study. RESULTS Ultimately, 24635 patients were undergoing TURBT, while 190 and 438 patients were, respectively, assigned to the PC and RC groups. Compared with patients with TURBT, a tendency of a higher proportion of higher older and male patients was observed in the PC group. When matching with RC patients, patients in the PC group were commonly older and had bigger tumor sizes and single tumors (All P < 0.05). After 1 : 1 PSM, 190 patients with TURBT and 160 patients receiving PC were selected. In survival analysis, the patients in the PC group had a higher survival probability of both OS and CSS before and after PSM compared with those in the TURBT group. Meanwhile, no significant differences were observed between the RC and PC groups in OS and CSS analysis. Moreover, multivariable Cox regression showed that PC was a protective factor for overall mortality (ACM) and cancer-specific mortality (CSM) compared with TURBT in T1 high-grade patients (All P < 0.05). CONCLUSION Patients undergoing partial cystectomy were shown to have a better outcome compared with those with transurethral bladder tumor resection in T1 high-grade bladder cancer patients. Partial cystectomy could be the more worthwhile choice for bladder preservation in T1 high-grade bladder cancer patients.

Evaluation of a Dual PI3K/mTOR Inhibitor PF-04691502 against Bladder Cancer Cells. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:8110796. [PMID: 35783514 PMCID: PMC9249467 DOI: 10.1155/2022/8110796] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/14/2022] [Accepted: 05/17/2022] [Indexed: 11/28/2022]
Abstract
Targeting the phosphatidylinositol-3 kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) signalling pathway is a promising strategy for the treatment of various cancers, including bladder cancer (BC). PF-04691502 is a relatively novel dual PI3K/mTOR inhibitor that exerts inhibitory effects against various cancer cells. However, the effects of PF-04691502 in BC cells have not been clarified thus far. This study aimed to evaluate the antitumour effects of PF-04691502 and the mechanisms underlying these antitumour effects in BC cells. The effects of PF-04691502 on the viabilities of BC cells were examined using the cell counting kit 8 (CCK-8) assay. Cell migration and invasion were measured using the wound healing assay and transwell assay, respectively. Cellular apoptosis was determined using flow cytometry. The change in the cellular protein levels was measured using western blotting. siRNA was used to study the role of PTEN in the antitumour effects of PF-04691502. PF-04691502 inhibited the proliferation, migration, and invasion of BC cells. Additionally, PF-04691502 induced apoptosis of BC cells via the intrinsic pathway. PF-04691502 inhibited the expression of Mcl-1 and the PI3K/Akt/mTOR pathway in BC cells. In addition, PF-04691502 increased the apoptosis induced by various chemotherapeutic agents in BC cells. Taken together, PF-04691502 could be used alone or in combination with other chemotherapeutic agents in the treatment of BC.

Abstract
The anti-cancer effects of [6]-gingerol ([6]-GIN), the main active polyphenol of ginger (Zingiber officinale), were investigated in the human bladder cancer cell line 5637. [6]-GIN inhibited cell proliferation, increased sub‑G1 phase ratios, and depolarized mitochondrial membrane potential. [6]-GIN-induced cell death was associated with the downregulation of B‑cell lymphoma 2 (BCL‑2) and survivin and the upregulation of Bcl‑2‑associated X protein (Bax). [6]-GIN activated caspase‑3 and caspase-9 and regulated the activation of mitogen-activated protein kinases (MAPKs). Further, [6]-GIN also increased the intracellular reactive oxygen species (ROS) levels and TG100-115 or tranilast increased [6]-GIN‑induced cell death. These results suggest that [6]-GIN induced apoptosis in the bladder cancer cell line 5637 and therefore has the potential to be used in the development of new drugs for bladder cancer treatment.

Abstract
An urgent need of therapy exists for patients with high-risk non-muscle invasive bladder cancer (NMIBC) for whom Bacillus Calmette-Guérin (BCG) refractory treatment has failed. We investigated the role of intravesical magnesium sulfate (MgSO4) therapy in the management of BCG refractory T1 high grade (G3) NMIBC. Between January 2018 and July 2021, we performed a prospective trial enrolling participants with T1 G3 NMIBC refractory in BCG therapy. All patients included were considered ineligible for or have refused to undergo radical cystectomy. Subjects are enrolled into a single treatment group of a fixed dose of intravesical MgSO4. The intravesical solution was given for 3 h bi-weekly × 6 then once per week for 12 months. Cystoscopic surveillance was performed every 3 months. Endoscopic resection was performed if suspicious findings were identified on surveillance cystoscopy to establish pathologic diagnosis. Oncological outcomes and any side effects were reported during follow-up. A total of 8 patients who received intravesical MgSO4 for refractory TG3 tumors were included in our study. The median follow-up time was 29 months (range from 23 to 36). 62.5% of the patients (5/8) achieved a complete response to intravesical MgSO4, while 25% of the patients (2/8) had a partial response and 12.5% (1/8) had persistent disease. None of the patients had disease progression. None of the patients experienced hypermagnesemia. In patients with pTG3 tumors who were refractory to BCG therapy, intravesical MgSO4 was a well-tolerated and potentially effective regimen.

Three-Dimensional Conformal Radiotherapy Combined with Gemcitabine and Docetaxel in the Treatment of Advanced Bladder Cancer and Its Effects on Inflammatory Factors and Immune Function. JOURNAL OF ONCOLOGY 2022; 2022:9347218. [PMID: 35466316 PMCID: PMC9023190 DOI: 10.1155/2022/9347218] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/23/2021] [Accepted: 02/28/2022] [Indexed: 11/17/2022]
Abstract
Objective. To assess the efficacy of three-dimensional conformal radiotherapy (3D-CRT) combined with GT chemotherapy (gemcitabine+docetaxel) in the treatment of advanced bladder cancer and its influence on inflammatory factors and immune function. Methods. A total of 42 elderly patients with advanced bladder cancer who were admitted to our hospital from January 2019 to January 2020 were included and assigned to the GT group (21 cases) receiving GT chemotherapy and combination group (21 cases) given 3D-CRT combined with GT chemotherapy. The clinical efficacy, immune function, inflammatory factors, tumor markers, urinary angiogenesis molecules before and after treatment, 1-year survival rate, 2-year survival rate, and incidence of adverse reactions of the two groups were compared. SPSS 22.0 statistical software was used for data processing and analysis. Results. The combination group had 5 cases of CR, 12 cases of PR, 3 cases of SD, and 1 case of PD, with an ORR of 80.95% (17/21), which was remarkably higher than the ORR of 57.14% (12/21) in the GT group which had 3 cases of CR, 9 cases of PR, 5 cases of SD, and 4 cases of PD (
). The 1-year survival rate of the combination group was 76.19% (16/21), and the 2-year survival rate was 47.62% (10/21), which were higher than the 1-year survival rate of 47.62% (10/21) and 2-year survival rate of 19.05% (4/21) in the GT group (
). The two groups presented similar results in terms of adverse reactions rate (
). After treatment, the combination group obtained significantly lower levels of urinary bladder cancer antigen (UBC), nuclear matrix protein-22 (NMP-22), vascular endothelial growth factor (VEGF), and basic fibroblast growth factor (bFGF) than the GT group (
). The CD3+, CD4+, and CD4+/CD8+ levels of the two groups of patients were lower than those before treatment (
), but no statistical difference was observed between the two groups after treatment (
). The levels of interleukin-6 (IL-6) and interferon-γ (IFN-γ) of the two groups witnessed a decline after treatment, with lower results in the combination group as compared to the control group (
). Before treatment, no significant difference in the Generic Quality of Life Inventory-74 (GQOLI-74) score between the two groups was found (
). After treatment, the combination group had higher GQOLI-74 scores than the GT group (
). Conclusion. 3D-CRT combined with GT chemotherapy yields a significant effect on the treatment of elderly advanced bladder cancer by effectively protecting immune function, mitigating inflammation, inhibiting tumor marker levels and the expression of angiogenic molecules, and improving patients’ survival.

Abstract
Vaccines can stimulate the immune system to protect individuals from infectious diseases. Moreover, vaccines have also been applied to the prevention and treatment of cancers. Due to advances in genetic engineering technology, cancer vaccines could be genetically modified to increase antitumor efficacy. Various genes could be inserted into cells to boost the immune response, such as cytokines, T cell costimulatory molecules, tumor-associated antigens, and tumor-specific antigens. Genetically modified cancer vaccines utilize innate and adaptive immune responses to induce durable antineoplastic capacity and prevent the recurrence. This review will discuss the major approaches used to develop genetically modified cancer vaccines and explore recent advances to increase the understanding of engineered cancer vaccines.

Abstract
Circular RNAs (circRNAs) are key regulatory factors in the development of multiple cancers. This study is targeted at exploring the effect of circ_0002623 on bladder cancer (BCa) progression and its mechanism. Circ_0002623 was screened out by analyzing the expression profile of circRNAs in BCa tissues. Circ_0002623, miR-1276 and SMAD2 mRNA expression levels in clinical sample tissues and cell lines were detected through quantitative real-time polymerase chain reaction (qRT-PCR). After circ_0002623 was overexpressed or silenced in BCa cells, the cell proliferation, migration and cell cycle were evaluated by CCK-8, BrdU, Transwell assay and flow cytometry. Tumor xenograft model was used to validate the biological function of circ_0002623 in vivo. Bioinformatics analysis and dual-luciferase reporter gene assay were conducted for analyzing and confirming, respectively, the targeted relationship between circ_0002623 and miR-1276, as well as between miR-1276 and SMAD2. The regulatory effects of circ_0002623 and miR-1276 on the expression levels of TGF-β, WNT1 and SMAD2 in BCa cells were detected by Western blot. We reported that, in BCa tissues and cell lines, circ_0002623 was up-regulated, whereas miR-1276 was down-regulated. Circ_0002623 positively regulated BCa cell proliferation, migration and cell cycle progression. Additionally, circ_0002623 could competitively bind with miR-1276 to increase the expression of SMAD2, the target gene of miR-1276. Furthermore, circ_0002623 could regulate the expression of TGF-β and WNT1 via modulating miR-1276 and SMAD2. This study helps to better understand the molecular mechanism underlying BCa progression.

Abstract
Background Recent studies indicate that bladder cancer is among the top 10 most common cancers in the world (Saginala et al. 2022). Bladder cancer frequently reoccurs, and prognostic judgments may vary among clinicians. As a favorable prognosis may help to inform less aggressive treatment plans, classification of histopathology slides is essential for the accurate prognosis and effective treatment of bladder cancer patients. Developing automated and accurate histopathology image analysis methods can help pathologists determine the prognosis of patients with bladder cancer. Materials and methods In this study, we introduced Bladder4Net, a deep learning pipeline, to classify whole-slide histopathology images of bladder cancer into two classes: low-risk (combination of PUNLMP and low-grade tumors) and high-risk (combination of high-grade and invasive tumors). This pipeline consists of four convolutional neural network (CNN)-based classifiers to address the difficulties of identifying PUNLMP and invasive classes. We evaluated our pipeline on 182 independent whole-slide images from the New Hampshire Bladder Cancer Study (NHBCS) (Karagas et al., 1998; Sverrisson et al., 2014; Sverrisson et al., 2014) collected from 1994 to 2004 and 378 external digitized slides from The Cancer Genome Atlas (TCGA) database (https://www.cancer.gov/tcga). Results The weighted average F1-score of our approach was 0.91 (95% confidence interval (CI): 0.86–0.94) on the NHBCS dataset and 0.99 (95% CI: 0.97–1.00) on the TCGA dataset. Additionally, we computed Kaplan–Meier survival curves for patients who were predicted as high risk versus those predicted as low risk. For the NHBCS test set, patients predicted as high risk had worse overall survival than those predicted as low risk, with a log-rank p-value of 0.004. Conclusions If validated through prospective trials, our model could be used in clinical settings to improve patient care.

Abstract
BACKGROUND AND AIMS Ankaferd Blood Stopper (ABS) was used for in vitro studies of osteosarcoma and colon carcinoma cancer cell lines to reveal the apoptotic and antineoplastic effects. The aim of this study is to evaluate the antineoplastic effect of ABS on bladder cancer cell cultures. METHODS We prospectively collected minimum 0.5 cm parts of fresh frozen tumour samples from patients with bladder tumour from 2015 to 2017. Primary bladder cancer cultures were produced from the frozen tumour samples. Two different doses of ABS were used on cancer cell cultures. Viability tests of each cell cultures were performed. Flow cytometry was used for the determination of apoptosis and necroptosis. We also checked the effect of ABS on different stages, grade and variant histology of bladder cancer cells. The results of all cancer cell cultures were compared with their own controls. RESULTS This study included 24 patients. Mean age of patients was 66.2 ± 11.7 years (34-83 years), where 19 of them (79.5%) were males and five (20.5%) were females. When we compared the data, we found decreased cancer cell viability ratio in each ABS group compared with their own controls. Necroptosis was observed in the great majority of ABS groups, and necroptosis and apoptosis were observed in some cell cultures. CONCLUSIONS In this study, we demonstrated the cytotoxic effect of ABS on bladder cancer cells. The results of this study suggests planning of animal model of bladder cancer for ABS with intravesical application as an antineoplastic agent. In the future, ABS may be a candidate intravesical treatment agent for bladder cancer.

Abstract
Cannabidiol (CBD), a primary bioactive phytocannabinoid extracted from hemp, is reported to possess potent anti-tumorigenic activity in multiple cancers. However, the effects of CBD on bladder cancer (BC) and the underlying molecular mechanisms are rarely reported. Here, several experiments proved that CBD promoted BC cells (T24, 5637, and UM-UC-3) death. For example, T24 cells were treated with 12 µM CBD for 48 h, flow cytometry analysis demonstrated that early and late apoptotic cells were accounted for by 49.91%, indicating CBD enhanced cell apoptosis ability. To deeper explore molecular mechanisms, the CBD-treated T24 cell transcriptome libraries were established. KEGG analysis implied that the significantly changed genes were enriched in the PI3K/Akt pathway. qRT-PCR and Western blot assays verified that CBD regulated BC cells growth and migration and induced apoptosis by inactivating the PI3K/Akt pathway. Meanwhile, the developed chitosan to wrap CBD-loaded PLGA nanoparticles can significantly enhance the adhesion of the material to the mouse bladder wall, and the binding efficiency of mucin to chitosan-PLGA nanoparticles reached 97.04% ± 1.90%. In summary, this work demonstrates that CBD may become a novel reliable anticancer drug and the developed intravesical adhesion system is expected to turn into a potential means of BC chemotherapy drug delivery.

Oridonin Promotes Apoptosis and Restrains the Viability and Migration of Bladder Cancer by Impeding TRPM7 Expression via the ERK and AKT Signaling Pathways. BIOMED RESEARCH INTERNATIONAL 2021; 2021:4340950. [PMID: 34285910 PMCID: PMC8275389 DOI: 10.1155/2021/4340950] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/13/2020] [Revised: 04/01/2021] [Accepted: 06/04/2021] [Indexed: 12/12/2022]
Abstract
BACKGROUND Oridonin is a powerful anticancer compound found in Rabdosia rubescens. However, its potential impact on bladder cancer remains uninvestigated. In this work, we aimed to detect the anticancer effect of oridonin on bladder cancer and explore the molecular mechanisms involved. METHODS The anticancer activity of oridonin was assessed in vitro with a CCK8 assay, an annexin V-FITC apoptosis analysis, and colony formation and Transwell migration assays which were performed with the human bladder cancer cell line T24. Levels of apoptosis-related proteins, melastatin transient receptor potential channel 7 (TRPM7), and signaling molecules were examined in oridonin-treated T24 cells by western blotting or RT-PCR. Oridonin anticancer efficacy was further validated in vivo with a T24 xenograft mouse model. RESULTS Oridonin repressed the proliferative, colony-forming, and migratory capacities of T24 cells, triggered extensive apoptosis in vitro, and retarded tumor growth in vivo. Moreover, oridonin treatment significantly increased expression levels of p53 and cleaved caspase-3 and reduced expression of TRPM7, p-AKT, and p-ERK. CONCLUSION Oridonin exhibited outstanding antiproliferative and antimigratory effects on bladder cancer, and these effects were at least partially associated with targeting of TRPM7 through inactivation of the ERK and AKT signaling pathways. These findings provide insight for the clinical application of oridonin in bladder cancer prevention.

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

Comparison of Side Effects and Tolerability Between Intravesical Bacillus Calmette-Guerin, Reduced-Dose BCG and Gemcitabine for Non-Muscle Invasive Bladder Cancer. Urology 2021; 156:191-198. [PMID: 34217763 DOI: 10.1016/j.urology.2021.04.062] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2021] [Revised: 03/28/2021] [Accepted: 04/01/2021] [Indexed: 11/29/2022]
Abstract
OBJECTIVES To compare patient-reported side effects and tolerability of full-dose Bacillus Calmette-Guérin (BCG), reduced-dose BCG, and gemcitabine one week after administration. METHODS All patients from July 2019 to November 2020 receiving intravesical therapy (IVT) for non-muscle invasive bladder cancer (NMIBC) at our institution were surveyed before repeat instillation. Survey questions recorded IVT retention times and the duration and severity of the following side effects: bladder symptoms, fatigue, body aches, hematuria, fever, chills, and other. All responses were collected and quantified in a de-identified, password-protected database. Statistical analysis was performed using SAS JMP 13. RESULTS Of 592 surveys completed, symptoms of any kind were reported on 463 surveys (78%) with the most common symptoms including bladder symptoms (59%), fatigue (52%), body aches (26%), and hematuria (18%). Patients were able to hold full-dose BCG, reduced-dose BCG, and gemcitabine for the protocol-specified duration 87%, 95%, and 71% of the time (P <0.05). The prevalence, severity, and duration of body aches were highest with gemcitabine (P <0.05) while the prevalence and duration of hematuria were higher with BCG (P <0.05). Reduced-dose BCG had the lowest prevalence, severity, and duration of fatigue (P <0.05). CONCLUSION Significant differences in the side effects and tolerability of full-dose BCG, reduced-dose BCG, and gemcitabine were demonstrated using this novel survey, and these differences are of value for informing IVT selection. Evaluation of IVTs other than gemcitabine and BCG will further inform selection of therapies for NMIBC.

Anticancer Agents Med Chem 2021; 20:1571-1581. [PMID: 32357825 DOI: 10.2174/1871520620666200502004002] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2019] [Revised: 01/11/2020] [Accepted: 02/28/2020] [Indexed: 11/22/2022]
Abstract
AIMS The purpose of our study was to explore the combination effect of epirubicin and Bacillus Calmette Guerin (BCG) and its mechanism. BACKGROUND Bladder cancer is a threat to human health worldwide. Commonly used chemotherapy drugs and biotherapy have significant therapeutic effects on bladder cancer, but the mechanism and combined effects are still unclear. OBJECTIVE To evaluate the anti-cancer effect of epirubicin combined with BCG on human bladder cancer cells, our studies were carried out. METHODS The viability of human bladder cancer cells with epirubicin and/or BCG treatments was examined by Cell Counting Kit-8 (CCK-8) assay. Apoptosis and cell cycle phase were determined by flow cytometry analysis. Pre-apoptosis factors of caspase-3, p53, B-cell lymphoma 2 associated X protein (Bax) and anti-apoptosis factor of B-cell lymphoma 2 (Bcl-2) were detected by western blot. RESULTS The viability of human bladder cancer with epirubicin or BCG treatment was decreased and the viability with epirubicin combined with BCG treatment was decreased more, which were determined by CCK-8 assay. Both epirubicin and BCG increased the apoptosis rate of human bladder cancer and arrested more cells into G0/G1 phase, which were tested by flow cytometry. The expression of caspase-3, p53 and Bax was increased and the expression of Bcl-2 was decreased with epirubicin treatment on human bladder cells, which were analyzed by western blot. The expression of caspase-3 and p53 was increased with BCG treatment, which was examined by western blot. CONCLUSION Epirubicin induced apoptosis in human bladder cancer cells by up-regulating the expression of proapoptotic factors (caspase-3, p53 and Bax) and down-regulating the expression of anti-apoptotic factor (Bcl-2). BCG promoted apoptosis of human bladder cancer cells by up-regulating the expression of caspase-3 and p53. BCG plays a potential role at the time of the combination of epirubicin and BCG on bladder cancer cells in early stage. Both epirubicin and BCG affected cell cycle distribution via arresting more bladder cancer cells at G0/G1 phase, which ultimately led bladder cancer proliferation in vitro and promoted apoptosis.

Immune Checkpoint Inhibitors in Urothelial Carcinoma: Recommendations for Practical Approaches to PD-L1 and Other Potential Predictive Biomarker Testing. Cancers (Basel) 2021; 13:cancers13061424.

Abstract
Simple Summary The predominant histologic type of bladder cancer is urothelial carcinoma (UC). Programmed cell death-ligand 1 (PD-L1) expression levels in UC tumors help clinicians determine which patients are more likely to respond to immuno-oncology (IO) therapies; as such, the harmonization of PD-L1 testing in evaluating patients is increasingly important. A series of international workshops, involving renowned pathologists and oncologists, were held to develop best practice approaches to PD-L1 testing in UC. It was agreed that robust control of analytical standards is required to obtain quality PD-L1 results and that interpretation and reporting of PD-L1 require clear inter-clinician communication. Recommendations for the best practices for PD-L1 testing in UC are provided. A PD-L1 test request form for pathology laboratories was also developed and included here, encouraging communication between clinicians and pathologists, and ensuring fast and high-quality test results. Novel biomarkers being evaluated for immuno-oncology agents in UC are also briefly discussed. Abstract Immuno-oncology (IO) agents (anti–programmed cell death 1 (PD-1) and anti–programmed cell death-ligand 1 (PD-L1)) are approved as first- and second-line treatments for metastatic UC. PD-L1 expression levels in UC tumors help clinicians determine which patients are more likely to respond to IO therapies. Assays for approved IO agents use different antibodies, immunohistochemical protocols, cutoffs (defining “high” vs. “low” PD-L1 expression), and scoring algorithms. The robust control of pre-analytical and analytical standards is needed to obtain high-quality PD-L1 results. To better understand the status and perspectives of biomarker-guided patient selection for anti–PD-1 and anti–PD-L1 agents in UC, three workshops were held from December 2018 to December 2019 in Italy, Malaysia, and Spain. The primary goal was to develop recommendations for best practice approaches to PD-L1 testing in UC. Recommendations pertaining to the interpretation and reporting of the results of PD-L1 assays from experienced pathologists and oncologists from around the globe are included. A test request form for pathology laboratories was developed as a critical first step for oncologists/urologists to encourage communication between clinicians and pathologists, ensuring fast and high-quality test results. In this era of personalized medicine, we briefly discuss novel biomarkers being evaluated for IO agents in UC.

Abstract
Introduction Chemohyperthermia is a feasible option in BCG (bacillus Calmette-Guérin) failure patients who desire bladder preservation. We aimed to assess outcomes and complications of chemohyperthermia using mitomycin C (MMC) or epirubicin (EPI). Material and methods From March 2017 to February 2020, 103 BCG failure or intolerance patients with high-risk NMIBC (non-muscle invasive bladder cancer) underwent a hyperthermic intravesical chemotherapy (HIVEC) regimen. Five patients did not complete at least 5 instillations and were excluded from analysis. MMC was used in 72 out of 98 patients (Group A) while EPI was used in 26 patients (Group B). Response to HIVEC, predictive factors for treatment outcome and the disease-free survival (DFS) were defined as primary endpoints. The complications of chemohyperthermia were assessed as a secondary endpoint. Results No significant differences were found in recurrence and progression after induction course between Groups A and B. Kaplan-Meier disease-free survival was 22.61 months in Group A and 21.93 in Group B. The log-rank test showed no statistically significant difference between the two curves (p = .627). In the multivariate analysis, patients with tumor size ≥3 cm (p = .029), recurrence rate >1/year (p = .034), concomitant carcinoma in situ (CIS) during transurethral resection of bladder (TURB) (p = .039) and BCG-unresponsive status (p = .048) were associated with a worse response to chemohyperthermia. The use of MMC or EPI did not influence the response to treatment (p = .157). A slightly significant higher rate of overall complications (p = .0488) was observed in Group B. A significantly higher rate of Grade 3 frequency/urgency (p = .0064) contributed to this difference. The use of EPI was the only independent factor associated with severe urinary frequency/urgency (p = .017). No patients experienced Grade 4/5 adverse events. Conclusions HIVEC can be considered a feasible option in BCG failure/intolerant NMIBC patients, avoiding or postponing radical cystectomy in some particular subclasses of patients.

Abstract
INTRODUCTION The treatment of low-grade upper tract urothelial carcinomas (UTUCs) after either surgery, or nephron-sparing techniques remains an unmet need in Genitourinary (GU) Oncology. UGN-101 is a novel drug in development for the treatment of UTUCs; it is composed of a sustained-release hydrogel polymer-based formulation containing the antitumor antibiotic mitomycin-C (MM-C); cold UGN-101 is liquid, but at body temperature, it becomes a gel, and thus, when administered through a ureteral catheter, it sticks to the upper tract urothelium, slowly releasing MM-C. AREAS COVERED Here, the authors review the preclinical rationale for the development of UGN-101, as well as presently available clinical results for the treatment of low-grade UTUCs. EXPERT OPINION The positive results of the recently completed OLYMPUS trial suggest the feasibility, activity (59% of complete responses, with just 6 of these complete responders on follow-up who recurred), and safety (68% of patients experiencing mild to moderate urinary adverse events) of UGN-101 instillations into the upper urinary tract. Our expectations are that UGN-101 will soon become a standard of treatment for low-grade UTUC at risk of relapse after either surgery, or nephron-sparing techniques.

Contemporary Treatment Patterns for Non-muscle-invasive Bladder Cancer: Has the Use of Radical Cystectomy Changed in the BCG Shortage Era? Urology 2020; 147:199-204. [PMID: 32805294 DOI: 10.1016/j.urology.2020.08.004] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2020] [Revised: 07/31/2020] [Accepted: 08/04/2020] [Indexed: 01/14/2023]
Abstract
OBJECTIVE To examine recent treatment trends for non-muscle-invasive bladder cancer (NMIBC), and specifically, to assess whether there was a change in use radical cystectomy (RC) between 2008 and 2015 using data from the Surveillance, Epidemiology, and End Results database. METHODS We identified patients presenting with high-grade T1 (T1HG) NMIBC at diagnosis during the study period. Treatment was dichotomized into "RC" and "local treatment" (which included transurethral resection and intravesical therapies). We then employed multivariable logistic regression models to assess the odds of undergoing RC across the study period. Additionally we examined the rates of RC for T1HG NMIBC during the period of BCG-shortage, defined as 2012-2015. RESULTS We identified 21,817 individuals diagnosed with T1HG bladder cancer during the study period. The majority of patients underwent local treatment (94.5%). During the shortage period, the rate of RC for T1HG NMIBC was significantly lower compared to the preshortage era (5.1% vs 5.9%, P = .007). Across the study period, the utilization of RC for T1HG NMIBC decreased significantly (odds ratio 0.99 per quarter, 95% confidence interval 0.98-0.99, P = .017). CONCLUSION In our cohort of patients diagnosed with T1HG bladder cancer, we found a significant decrease in the use of radical cystectomy across the study period. Contrary to the hypothesis of increasing rates of RC in the face of BCG shortage, the rate of RC was significantly higher in the pre-shortage era. Further examination of NMIBC treatment patterns will be necessary to assess the impact of BCG availability on therapeutic pathways and oncologic outcomes in patients with high-grade NMIBC.

Quality of life and adverse events in patients with nonmuscle invasive bladder cancer receiving adjuvant treatment with BCG, MMC, or chemohyperthermia. Urol Oncol 2020; 39:76.e9-76.e14. [PMID: 32753359 DOI: 10.1016/j.urolonc.2020.07.003] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2020] [Revised: 05/25/2020] [Accepted: 07/01/2020] [Indexed: 11/29/2022]
Abstract
INTRODUCTION Chemohyperthermia (CHT) with mitomycin C (MMC) is together with Bacillus Calmette-Guérin (BCG), and passive MMC, a treatment option for patients with non muscle-invasive bladder cancer. There are no data published about the impact of CHT in quality of life (QoL). We evaluated QoL and adverse events (AE) in this 3-arm observational study. PATIENTS AND METHODS Prospective observational study from September 2016 to March 2017, we recruited consecutive patients that received adjuvant treatment after transurethral resection of bladder tumor. Patients received induction courses of either BCG, CHT, or passive MMC. Patients filled the questionnaires Functional assessment of cancer therapy for bladder cancer patients (FACT-Bl) and International prostate symptom score (IPSS) before, during, and after the induction course. A urologist documented AE using Common Terminology Criteria for AE (CTCAE criteria). RESULTS A total of 56 patients, receiving a total of 296 bladder instillations (BCG n = 27, CHT n = 14 and MMC n = 15). FACT-Bl showed statistically significant differences in the fourth week in favor of CHT versus BCG, IPSS did not show statistically significant differences before, during, and after induction course in all 3 arms. All patients recovered their baseline QoL at the end of the induction treatment. Overall 55.5%, 50% and 20% of patients presented any grade of AE in the BCG, CHT and MMC groups respectively. About 7% of patients in BCG and CHT arms had to discontinue treatment due to AE. BCG and CHT showed a similar rate of AE but in CHT were mostly grade I and BCG had grade I, II, and IV. Passive MMC had the safest profile. CONCLUSION There are no clinically significant differences between BCG, CHT, and passive MMC regarding QoL and lower urinary tract symptoms during the induction course. CHT has a more favorable AE profile when compared with BCG.

Abstract
BACKGROUND Identification of bladder layers is a necessary prerequisite to bladder cancer diagnosis and prognosis. We present a method of multi-class image segmentation, which recognizes urothelium, lamina propria, muscularis propria, and muscularis mucosa layers as well as regions of red blood cells, cauterized tissue, and inflamed tissue from images of hematoxylin and eosin stained slides of bladder biopsies. METHODS Segmentation is carried out using a U-Net architecture. The number of layers was either, eight, ten, or twelve and combined with a weight initializers of He uniform, He normal, Glorot uniform, and Glorot normal. The most optimal of these parameters was found by through a seven-fold training, validation, and testing of a dataset of 39 whole slide images of T1 bladder biopsies. RESULTS The most optimal model was a twelve layer U-net using He normal initializer. Initial visual evaluation by an experienced pathologist on an independent set of 15 slides segmented by our method yielded an average score of 8.93 ± 0.6 out of 10 for segmentation accuracy. It took only 23 min for the pathologist to review 15 slides (1.53 min/slide) with the computer annotations. To assess the generalizability of the proposed model, we acquired an additional independent set of 53 whole slide images and segmented them using our method. Visual examination by a different experienced pathologist yielded an average score of 8.87 ± 0.63 out of 10 for segmentation accuracy. CONCLUSIONS Our preliminary findings suggest that predictions of our model can minimize the time needed by pathologists to annotate slides. Moreover, the method has the potential to identify the bladder layers accurately. Further development can assist the pathologist with the diagnosis of T1 bladder cancer.

Abstract
Background Small nucleolar RNAs (snoRNAs) are a new non-coding RNAs (ncRNAs), which have not been widely investigated and are identified to be involved in tumorigenesis. But the function of snoRNAs in BLCA has not been reported yet. Methods SnoRNAs signature (SNORS) was constructed through LASSO cox regression analysis. Integrated analysis of candidate snoRNAs was performed to detect the correlation between copy number variation (CNV)/DNA methylation/protein/mRNA/alternative splicing (AS). Then we built a nomogram integrating independent prognostic factors to assist the clinical utility. Results We have screened out 15 prognostic differentially expressed snoRNAs (DESs) and constructed SNORS consisting of 5 candidate snoRNAs which could appropriately stratify patients into low or high SNORS groups with distinct prognosis. Then we found 5 candidate snoRNAs might be regulated by their own CNV and DNA methylation. Moreover, 5 candidate snoRNAs were significantly correlated mRNA and alternative splicing (AS), which might regulate diverse biological process in tumorigenesis, such as "extracellular matrix", "epithelial-mesenchymal transition (EMT)", etc. signaling pathways. Furthermore, SNORS was an independent prognostic factor, which was strikingly correlated with clinical outcome. Through inporating with other variables, we have established a predictive nomogram, which was more effectively to predict prognosis than any other variables alone. Conclusion Our findings first highlighted an important role of snoRNAs in BLCA and established a potential prognostic model which could serve as a biomarker for BLCA.

Abstract
Background As bladder cancer was recognized to be immunogenic, dozens of studies have focused on immune biology of BLCA, but little is known about its relationship with the long non-coding RNAs (lncRNAs). Methods LASSO Cox regression model was used to establish immune-related lncRNAs signature (IRLS) in BLCA. The immune infiltration landscape of BLCA was conducted via ssGSEA and immunotherapy response was calculated through TIDE algorithm. Results A total of 82 immune-related lncRNAs were screened out according to spearman correlation analysis with the immune score (|R| > 0.4, p < 0.05). We selected 5 prognostic lncRNAs to construct immune-related lncRNAs signature (IRLS) through LASSO Cox regression analysis. Then we validated that 5 enrolled lncRNAs was downregulated in BLCA tissues and cells when compared with paracancerous tissues and normal bladder epithelium cell. The univariate and multivariate Cox regression analysis both demonstrated the IRLS was a robust independent prognostic factor in overall survival prediction with high accuracy. The GSVA and GSEA also suggested that the IRLS are involved in the immune-related biological processes and pathways which are very well known in the context of BLCA tumorigenesis. In addition, we found that IRLS is strikingly positive correlated with tumour microenvironment (TME) immune cells infiltration and expression of critical immune checkpoints, indicating that the poor prognosis might be caused partly by immunosuppressive TME. Finally, the results from the TIDE analysis revealed that IRLS could efficiently predict the clinical response of immunotherapy in BLCA. Conclusion We have developed a novel IRLS, which have a latent prognostic value for BLCA patients and might facilitate personalized counselling for immunotherapy.

Quantifying the Overall Survival Benefit With Early Radical Cystectomy for Patients With Histologically Confirmed T1 Non-muscle-invasive Bladder Cancer. Clin Genitourin Cancer 2020; 18:e651-e659. [PMID: 32335060 DOI: 10.1016/j.clgc.2020.03.013] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2019] [Revised: 03/20/2020] [Accepted: 03/22/2020] [Indexed: 11/23/2022]
Abstract
INTRODUCTION The objective of this study was to examine the overall survival (OS) in patients diagnosed with high-grade T1 non-muscle-invasive bladder cancer treated with early radical cystectomy versus local treatment of the primary tumor, defined as endoscopic management with or without intravesical chemotherapy or immunotherapy. PATIENTS AND METHODS We identified 4900 patients with histologically confirmed, clinically non-metastatic high-grade T1 bladder cancer undergoing surgical intervention using the National Cancer Database for the period 2010 to 2015. Multivariable logistic regression was used to examine predictors for the receipt of early radical cystectomy (defined as radical cystectomy within 90 days of diagnosis). We then employed multivariable Cox proportional hazards regression models and Kaplan-Meier curves to evaluate the OS according to surgical treatment (early radical cystectomy vs. local treatment). RESULTS A minority (23.7%) of patients underwent early radical cystectomy. Independent predictors of undergoing early radical cystectomy included lower age, White race, and lower comorbidity status. The median OS was 74.0 months for patients diagnosed with high-grade T1 bladder cancer. The 1- and 5-year survival rates of patients undergoing early radical cystectomy were 94.8% and 71.0%, whereas they were 85.2% and 52.4%, for patients undergoing initial local treatment, respectively (P < .001). Compared with patients undergoing local treatment, patients undergoing early radical cystectomy had a lower risk of all-cause mortality (hazard ratio, 0.78; 95% confidence interval, 0.67-0.91; P = .002). CONCLUSION In this cohort of patients presenting with high-grade T1 non-muscle-invasive bladder cancer, we found that early radical cystectomy was associated with an OS benefit compared with initial local treatment.

Abstract
In 2018 bladder cancer (urothelial carcinoma) was ranked twelfth concerning worldwide diagnosis of malignancies. At the time point of diagnosis of bladder cancer, approximately 75% of patients present with a nonmuscle-invasive disease (NMIBC), while the remaining 25% show invasion of tumor cells in the muscle layer of the bladder wall (MIBC). Among NMIBC tumors, flat, high-grade carcinoma in situ (CIS) is a therapeutic challenge. CIS shows a tendency to invade the muscle tissue of the bladder wall and thus become a MIBC. Standard therapy of NMIBC (including CIS) is done via intravesical instillation of BCG (bacillus Calmette Guerin) inducing a local immune reaction that finally promotes elimination of bladder cancer cells. However, BCG treatment of NMIBC proves to be ineffective in approximately 40% of patients. Therefore, new therapeutic approaches for the treatment of bladder cancer are urgently needed. Among promising new treatment options that are currently being investigated are the use of immune checkpoint inhibitors, and targeted approaches attacking (among others) long noncoding RNAs, micro RNAs, cancer stem cells, PARP1, and receptor signaling pathways. Moreover, the use of antibody-drug-conjugates (ADCs) is investigated also in bladder cancer therapy. Another approach that has been successfully established in preclinical studies uses the cytotoxic power of the alpha-emitter Bi-213 coupled to an antibody targeting EGFR. Overexpression of EGFR has been demonstrated in the majority of patients suffering from CIS. Feasibility, safety, toxicity and therapeutic efficacy of intravesical instillation of Bi-213-anti-EGFR have been evaluated in a pilot study. Since the results of the pilot study proved to be promising, a further optimization of alpha-emitter immunotherapy in bladder cancer seems mandatory.

Abstract
Physicians treating patients affected by nonmuscle-invasive bladder cancer (NMIBC) have been in shock during the last six years since manufacturing restrictions on the production of the first-option medicine, Mycobacterium bovis Bacillus Calmette-Guérin (BCG), have resulted in worldwide shortages. This shortage of BCG has led to a rethinking of the established treatment guidelines for the rationing of the administration of BCG. Some possible schedule modifications consist of a decrease in the length of maintenance treatment, a reduction in the dose of BCG in intravesical instillations or the use of different BCG substrains. All these strategies have been considered valuable in times of BCG shortage. In addition, the lack of availability of BCG has also led to the general recognition of the need to find new treatment options for these patients so that they are not dependent on a single treatment. Few alternatives are committed to definitively replacing BCG intravesical instillations, but several options are being evaluated to improve its efficacy or to combine it with other chemotherapeutic or immunotherapeutic options that can also improve its effect. In this article, we review the current state of the treatment with BCG in terms of all of the aforementioned aspects.

Abstract
Abstract
Introduction: The peritumoral inflammatory reaction has a substantial importance in the oncologic outcome of bladder cancer (BC). One biomarker proven to be practical and accessible is the NLR (neutrophil-to-lymphocyte ratio) for high risk non-muscle invasive bladder cancer (NMIBC). The aim of the study was to investigate the role of NLR as a prognostic biomarker for disease recurrence, progression and survival of p Ta (pathological assesment of the primary tumor) NMIBC.
Material and Methods: In our retrospective study we included 54 patients with pTa NMIBC from a total of 235 patients who underwent transurethral resection of bladder tumor (TURBT) during two consecutive years: January 2007 - December 2008 [median follow-up 106 months (interquartile range-IQR 68-116)]. Criteria for inclusion were: primary tumor, low-grade, with NLR available at 2 weeks prior to TURBT. NLR was considered altered if higher than 3.
Results: The median age of the patients included was 63 years (IQR 55 - 72). Most of the patients had NLR---lt---3 (37 patients). Median EORTC (European Organization of Research and Treatment of Cancer) Recurrence Score was 4 (IQR 1-6), while EORTC Progression Score was 3 (IQR 0-6), respectively. Recurrence occurred in 8 out of 54 (14.81 %) patients and progression was identified in 2 out of 54 (3.70 %) patients with muscle-invasive BC during follow-up. NLR---gt---3 was not associated with clinical and pathological factors. In multivariable Cox regression analyses NLR as a continuous variable was an independent predictive factor for recurrence. Recurrence-free survival (RFS) Kaplan-Meier analysis did not show a statistical significance between NLR groups: 82.67% vs. 64.12%, p=0.26. Kaplan-Meier analysis showed a lower Progression-free survival (PFS) in the NLR---gt---3 group: 94.12% vs. 100%, p=0.04. During follow-up (106 months) 18 patients deceased with no impact of NLR as a prognostic factor in multivariable analyses. Kaplan-Meier overall survival (OS) analysis showed a 10-year OS of 70.27% in the low NLR group compared with 58.82% in the high NLR group, p=0.45.
Conclusion: In this cohort, high NLR was associated with high recurrence rate in patients with Ta NMIBC. In low-risk NMIBC NLR could represent a valid biomarker for clinical usage regarding the intensity of follow-up schedule.

Abstract
BACKGROUND Bladder hyperthermic intracavitary chemotherapy (HIVEC) has good effectiveness for bladder cancer, but conventional HIVEC systems lack precision and convenient application. To test the safety of a new HIVEC device (BR-TRG-II-type) in pigs and to perform a preliminary clinical trial in patients with bladder cancer. METHODS This device was tested on six pigs to optimize the temperature and time parameters. Then, 165 patients (HIVEC after transurethral resection (TUR), n = 128; or HIVEC, n = 37) treated between December 2006 and December 2016 were recruited. Mitomycin C (MMC) was the chemotherapeutic agent. A serum pharmacokinetic study was performed. The primary endpoints were tumor recurrence, disease-free survival (DFS), and cumulative incidence rate (CIR) during follow-up. The adverse effects were graded. RESULTS The animal experiment showed that 45 °C for 1 h was optimal. HIVEC was successful, with the infusion tube temperature stably controlled at about 45 °C, and outlet tube temperature of about 43 °C in all patients, for three sessions. Serum MMC levels gradually increased during HIVEC and decreased thereafter. The mean DFS was 39 ± 3.21 months (ranging from 8 to 78 months), and the DFS rate was 89.1% during follow-up. No adverse events occurred. CONCLUSION The use of the BR-TRG-II-type HIVEC device is feasible for the treatment of bladder cancer. Future clinical trials in patients with different stages of bladder cancer will further confirm the clinical usefulness of this device.

Abstract
Non-muscle-invasive bladder cancer (NMIBC) remains one of the most common malignancies and is associated with considerable treatment costs. Patients with intermediate-risk or high-risk disease can be treated with intravesical BCG, but many of these patients will experience tumour recurrence, despite adequate treatment. Standard of care in these patients is radical cystectomy with urinary diversion, but this approach is associated with considerable morbidity and lifestyle modification. As an alternative, perioperative intravesical chemotherapy is recommended for low-risk papillary NMIBC, and induction intravesical chemotherapy is an option for patients with intermediate-risk NMIBC and BCG-unresponsive NMIBC. However, poor pharmaceutical absorption and drug washout during normal voiding can limit sustained drug concentrations in the urothelium, which reduces efficacy, and small-molecule chemotherapeutic agents can be absorbed through the urothelium into the bloodstream, leading to systemic adverse effects. Several novel drug delivery methods - including hyperthermia, mechanical sustained released devices and nanoparticle drug conjugation - have been developed to overcome these limitations. These novel methods have the potential to be combined with established chemotherapeutic agents to change the paradigm of NMIBC treatment.

Abstract
Bladder cancer (BC) is a common disease in both sexes and majority of cases present as non-muscle invasive BC (NMIBC). The percentage of NMIBC progressing to muscle invasive BC (MIBC) varies between 25% and 75% and currently there are no reliable molecular markers that may predict the outcome of high-risk (HR) NMIBC. Transurethral resection of the bladder tumour (TURBT) with intravesical bacillus Calmette-Guérin (BCG) or immediate radical cystectomy (RC) are the current gold standard treatment options. The European Association of Urology (EAU) guidelines recommend immediate or delayed RC for HR- and a subgroup of “highest-risk” NMIBC. These cases include pT1, carcinoma in-situ (CIS), multifocal disease, histological variants such as micropapillary and sarcomatoid, and patients who have contraindications to, or have failed with BCG. The comparative risks between maintenance BCG (mBCG) and immediate RC are unclear. However, RC may give patients the best oncological outcome.

Abstract
PURPOSE OF REVIEW As our molecular understanding of bladder cancer continues to advance, more and more novel agents are entering clinical trials across the spectrum of bladder cancer stages. The clinical trial activity for non-muscle invasive bladder cancer (NMIBC) has been boosted further by the evolution of specific disease states that set more uniform inclusion criteria for clinical trial design. Here, we aimed to review the current clinical trials landscape in non-muscle invasive bladder cancer with respect to these disease states. RECENT FINDINGS Most active clinical trials focus on high-risk NMIBC in either the BCG-naïve or BCG-unresponsive setting. Strict criteria to define the disease state and a clear pathway to drug registration have encouraged trials for patients with BCG-unresponsive NMIBC. The most promising potential breakthroughs for BCG-naïve patients include alternative BCG strains, immune-priming with intradermal BCG vaccination, and systemic immune checkpoint blockade. The latter therapy is also being actively investigated in multiple trials in BCG-unresponsive NMIBC, along with novel viral agents such as INSTILADRIN (nadofaragene firadenovec) and targeted agents such as oportuzumab monatox. After many years of relative stagnation, multiple new therapies currently under investigation in well-designed clinical trials appear poised for routine clinical implementation in the near future. These therapies should dramatically improve the outcome of patients with NMIBC. We can look forward to the challenges of biomarker-driven drug selection, optimal drug sequencing, and rational combination therapies.

Therapeutic efficacy of the live-attenuated Mycobacterium tuberculosis vaccine, MTBVAC, in a preclinical model of bladder cancer. Transl Res 2018; 197:32-42.

Abstract
Intravesical instillation of bacillus Calmette-Guérin (BCG) has been a first-line therapy for non-muscle-invasive bladder cancer for the last 4 decades. However, this treatment causes serious adverse events in a significant number of patients and a substantial percentage of recurrence episodes. MTBVAC is a live-attenuated vaccine derived from a Mycobacterium tuberculosis clinical isolate and is currently under evaluation in clinical trials to replace BCG as a tuberculosis vaccine. Here, we describe for the first time the potential of MTBVAC as a bladder cancer therapy in vitro and in vivo in a preclinical model. MTBVAC colonized human bladder tumor cells to a much greater extent than BCG via a mechanism mediated by macropinocytosis and induced cell growth inhibition after internalization. In vivo testing in an orthotopic murine model of bladder cancer demonstrated a higher antitumor effect of MTBVAC in experimental conditions in which BCG did not work. Our data encourage further studies to support the possible application of MTBVAC as a new immunotherapeutic agent for bladder cancer.

Abstract
PURPOSE Topical therapy (TT) for upper tract urothelial carcinoma (UTUC) has been explored as a kidney sparing approach to treat carcinoma in situ (CIS) and as adjuvant for endoscopically treated Ta/T1 tumors. In bladder cancer, data support use of salvage TT for repeat induction. We investigate the outcomes of salvage TT for UTUC in patients ineligible for or refusing nephroureterectomy. METHODS A single-center retrospective review on patients receiving salvage TT via percutaneous nephrostomy tube or cystoscopically placed ureteral catheters was performed. Primary outcome was response to therapy based on International Bladder Cancer Group criteria. RESULTS 51 patients with 58 renal units (RUs) received TT. Of these, 17 patients with 18 RUs received the second-line TT, with a median follow-up of 36.5 months (IQR 24.5-67 months). 44% (8/18) received salvage TT for refractory disease and 56% (10/18) as reinduction. 5 RUs with CIS were unresponsive to initial TT and went on to receive salvage TT, of which 20% (1/5) responded. 13 RUs recurred or relapsed following initial TT and received salvage TT for papillary tumors, with 62% (8/13) responding. CONCLUSION Our data provide preliminary clinical rationale for the second-line TT for refractory and recurrent, endoscopically managed papillary UTUC in patients ineligible for or refusing nephroureterectomy. However, refractory upper tract CIS appears to have poor response to salvage TT.

Abstract
BACKGROUND The treatment options for non-muscle invasive bladder cancer (NMIBC) remain limited. Bacillus Calmette-Guerin (BCG) was the last major breakthrough in bladder cancer therapy almost 4 decades ago. There have been improvements in the understanding of immune therapies and cancer biology, leading to the development of novel agents. This has led to many clinical trials that are currently underway to find the next generation of therapies for NMIBC. METHOD We reviewed clinicaltrials.org and pubmed.gov to find the recently completed and ongoing clinical trials in NIMBC. Included in this review are clinical trials that are currently active and trials that were completed in and after 2014. RESULT Many trials with BCG-naive and BCG-unresponsive/recurrent/refractory/failure patients with NMIBC are either currently underway or have been recently completed. A wide variety of novel therapeutic agents are being investigated that range from cytotoxic agents to immunomodulatory agents to targeted molecular therapies. Other approaches include cancer vaccines, gene therapies, and chemoradiation potentiation agents. Novel drug-delivery methods are also being tested. CONCLUSION This comprehensive update of current trials provides researchers an overview of the current clinical trial landscape for patients with NMIBC.

Abstract
Analyses of microRNA (miRNA) expression signatures obtained by RNA sequencing revealed that some passenger miRNAs (miR-144-5p, miR-145-3p, miR-149-3p, miR-150-3p, and miR-199a-3p) acted as anti-tumor miRNAs in several types of cancer cells. The involvement of passenger strands in the pathogenesis of human cancer is a novel concept. Based on the miRNA signature of bladder cancer (BC) obtained by RNA sequencing, we focused on both strands of the miR-223-duplex (miR-223-5p and miR-223-3p) and investigated their functional significance in BC cells. Ectopic expression of these miRNAs showed that both miR-223-3p (the guide strand) and miR-223-5p (the passenger strand) inhibited cancer cell migration and invasion of BC cells. The role of miR-223-5p (the passenger strand) has not been well studied. Combining gene expression studies and in silico database analyses, we demonstrated the presence of 20 putative target genes that could be regulated by miR-223-5p in BC cells. Among these targets, high expression of five genes (ANLN, INHBA, OIP5, CCNB1, and CDCA2) was significantly associated with poor prognosis of BC patients based on The Cancer Genome Atlas (TCGA) database. Moreover, we showed that a gene (ANLN) encoding a multifunctional actin-binding protein was directly regulated by miR-223-5p in BC cells. Overexpression of ANLN was observed in BC clinical specimens and high expression of ANLN was significantly associated with poor prognosis of BC patients. We suggest that studies of regulatory cancer networks, including the passenger strands of miRNAs, may provide new insights into the pathogenic mechanisms of BC.

Abstract
Objective: This study aimed to investigate the expression of cyclin D1 and hnRNP-K in relation to the pathological findings in bladder cancer including the type, grade, muscle invasion and bilharzial association. Methods: We studied the immunoexpression; as regard the percentage, intensity and score of both cyclin D1 and hnRNP-K in different bladder lesions including 10 cases of cystitis; 10 cases of carcinoma insitu (CIS), 20 cases of Squamous cell carcinoma (SCC) and 66 cases of urothelial carcinoma (UC). Results: High expression of cyclin D1 was found in UC compared to other groups (p<0.001) and in UC with low grade, non-muscle invasive and papillary tumors compared to their counterparts (p<0.05, <0.01 and <0.05 respectively), however, bilharzial association does not affect cyclin D1 expression. Higher hnRNP-K expression was found in SCC compared to other groups (p <0.001) and in UC with high grade, muscle invasive and non-papillary tumors compared to their counterparts (p<0.001each). Bilharzial-associated UC showed higher expression of hnRNP-K percent (p<0.05) compared to non-bilharzial cases. Conclusion: This study elucidated a possible contribution of cyclin D1 and hnRNP-K expression in the initiation and progression of urinary bladder carcinoma, so, both of them can be used in predicting progression of urinary bladder carcinoma and to differentiate between UC and SCC in high grade tumors. The possible role of both markers in immunotherapy deserves supplementary studies.
