Abstract
Background We conducted this meta-analysis to compare the two muscle-invasive bladder cancer (MIBC) treatment modalities in terms of cancer-specific survival (CSS) and other outcome indicators. Method A systematic review and meta-analysis were performed in accordance with the Preferred Reporting Items for Systematic Reviews (PRISMA) guidelines. The search was conducted using various academic databases including Scopus, PubMed, Cochrane database, EMBASE, Chinese biomedical literature database, Wan fang databases, and China National Knowledge Internet databases between 1966 and December 2023. This review protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO) No. (CRD42023398977). Result This study included a total of 54,816 patients diagnosed with bladder cancer from 14 studies, of which 6,228 patients were assigned to the trimodal therapy (TMT) group and 48,588 patients were assigned to the radical cystectomy (RC) group. Based on the results, the RC group exhibited a higher rate of survival than the TMT group [pooled hazard ratio (HR) = 1.23, 95% CI: 1.18-1.28, Z = 1.46, P < 0.001]. In terms of CSS, patients in the RC group had a longer CSS compared with those in the TMT group (pooled HR = 1.47, 95% CI: 1.29-1.67, Z = 5.893, P < 0.001). Compared with RC, TMT is significantly associated with an increased risk of both types of mortality (pooled HR: 1.30, P < 0.001). Conclusion Overall, the findings of this meta-analysis suggest that RC treatment may be associated with improved overall survival. Moreover, it was observed that cancer-specific survival was significantly prolonged among patients in the RC group as opposed to those who received TMT. In addition, it was shown that patients who received TMT exhibited a higher risk of all-cause mortality when compared with those who underwent RC.

Abstract
OBJECTIVE To provide insight into the use and staging information on lymph-node involvement added by fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) in patients with muscle-invasive bladder cancer (MIBC), based on a nationwide population-based cohort study. PATIENTS AND METHODS We analysed a nationwide cohort of patients with MIBC without signs of distant metastases, newly diagnosed in the Netherlands between November 2017 and October 2019. From this cohort, we selected patients who underwent pre-treatment staging with CT only or CT and FDG-PET/CT. The distribution of patients, disease characteristics, imaging findings, nodal status (clinical nodal stage cN0 vs cN+) and treatment were described for each imaging modality group (CT only vs CT and FDG-PET/CT). RESULTS We identified 2731 patients with MIBC: 1888 (69.1%) underwent CT only; 606 (22.2%) underwent CT and FDG-PET/CT, 237 (8.6%) underwent no CT. Of the patients who underwent CT only, 200/1888 (10.6%) were staged as cN+, vs 217/606 (35.8%) who underwent CT and FDG-PET/CT. Stratified analysis showed that this difference was found in patients with clinical tumour stage (cT)2 as well as cT3/4 MIBC. Of patients who underwent both imaging modalities and were staged with CT as cN0, 109/498 (21.9%) were upstaged to cN+ based on FDG-PET/CT. Radical cystectomy (RC) was the most common treatment within both imaging groups. Preoperative chemotherapy was more frequently applied in cN+ disease and in FDG-PET/CT-staged patients. Concordance of pathological N stage after upfront RC was higher among patients staged as cN+ with CT and FDG-PET/CT (50.0% pN+) than those staged as cN+ with only CT (39.3%). CONCLUSION Patients with MIBC who underwent pre-treatment staging with FDG-PET/CT were more often staged as lymph node positive, regardless of cT stage. In patients with MIBC who underwent CT and FDG-PET/CT, FDG-PET/CT led to clinical nodal upstaging in approximately one-fifth. Additional imaging findings may influence subsequent treatment strategies.

Abstract
Background Bladder cancer (BCa) is a malignant tumor that usually forms cancer cells in the inner lining of the bladder. Hundreds of thousands of people worldwide have BCa diagnosed each year. The purpose of this study was to construct a prognostic model by differential expression of genes between muscular and non-muscular invasive BCa, and to investigate the prognosis of BCa patients. Methods The data of BCa patients was sourced from the GEO and TCGA database. Single-cell sequencing data was obtained from three patients in the GSE135337 database, and microarray data for verification was obtained from GSE32894. Univariate, Lasso and multivariate cox regression analyses were performed to construct the prognostic model. The prognostic features, immune features and drug sensitivity of the model were further evaluated. Single-cell data and microarray data were used to validate the differential expression of model genes between muscle-invasive and non-muscle-invasive BCa. The invasion and migration of BCa cells were evaluated using the transwell assay and wound-healing assay. The cell proliferation capacity was simultaneously evaluated using Colony formation experiments. The protein expression of the specific gene was detected by western blot analysis. Results We identified 183 differentially expressed muscle-invasive-related differential genes (MIRDGs), among which four were selected to establish a prognostic model. Based on our signature, patients in different groups displayed varying levels of immune infiltration and immunotherapy profiles. Single-cell sequencing data and microarray data confirmed that four invasion-related genes were expressed at higher levels in muscle-invasive BCa. Given the critical role of S100A9 in the progression of BCa, we performed further analysis. The results showed that protein expression of S100A9 was high in muscle-invasive BCa, and S100A9 knockdown could inhibit the proliferation, migration and invasion of BCa. Conclusion These findings demonstrated that the prognostic model for BCa patients was reasonably accurate and valid, and it may prove to be of considerable value for the treatment and prognosis of BCa patients in the future. S100A9 may become a better prognostic marker and potential therapeutic target to further guide clinical treatment decisions.

Abstract
Trimodal therapy (TMT) - maximal transurethral resection of bladder tumour followed by chemotherapy and radiation - is an effective treatment for some patients diagnosed with muscle-invasive bladder cancer. Yet eligible patients are not always offered this option or are unclear that this option is (or was) appropriate, desirable and available to them. Communication challenges are a critical barrier to delivering the high-quality care and shared decision-making that bladder cancer patients seek. Leveraging patient and clinician feedback, a checklist was created and is proposed that proactively addresses patients' concerns and questions and ensures that patients are well-informed about TMT. By using the checklist, members of multidisciplinary bladder cancer medical teams can ensure that patients are well-informed about TMT and are confident that TMT has been appropriately and jointly explored as a treatment option. The checklist can reduce communication challenges and frustrations and ensure that, through shared decision-making, patients have chosen their most appropriate treatment.

Abstract
The stem-cell-like behavior of cancer cells plays a central role in tumor heterogeneity and invasion and correlates closely with drug resistance and unfavorable clinical outcomes. However, the molecular underpinnings of cancer cell stemness remain incompletely defined. Here, we show that SNHG1, a long non-coding RNA that is over-expressed in ~95% of human muscle-invasive bladder cancers (MIBCs), induces stem-cell-like sphere formation and the invasion of cultured bladder cancer cells by upregulating Rho GTPase, Rac1. We further show that SNHG1 binds to DNA methylation transferase 3A protein (DNMT3A), and tethers DNMT3A to the promoter of miR-129-2, thus hyper-methylating and repressing miR-129-2-5p transcription. The reduced binding of miR-129-2 to the 3'-UTR of Rac1 mRNA leads to the stabilization of Rac1 mRNA and increased levels of Rac1 protein, which then stimulates MIBC cell sphere formation and invasion. Analysis of the Human Protein Atlas shows that a high expression of Rac1 is strongly associated with poor survival in patients with MIBC. Our data strongly suggest that the SNHG1/DNMT3A/miR-129-2-5p/Rac1 effector pathway drives stem-cell-like and invasive behaviors in MIBC, a deadly form of bladder cancer. Targeting this pathway, alone or in combination with platinum-based therapy, may reduce chemoresistance and improve longer-term outcomes in MIBC patients.

Abstract
INTRODUCTION There are substantial unmet needs with regards to adjuvant therapy for muscle-invasive urothelial carcinoma (UC) of the bladder, including patients with persistent disease histologically following neoadjuvant platinum-based therapy and radical resection, as well as patients who are not eligible for or refuse cytotoxic chemotherapy. As such, increased interest has been developed in advancing the use of systemic immunotherapy in the postoperative setting. AREAS COVERED We begin by examining current uses of systemic immunotherapy in the treatment of advanced UC. We also review emerging neoadjuvant data and describe current adjuvant approaches. We then report and analyze data on adjuvant immunotherapy, including the recent randomized trials on adjuvant nivolumab and atezolizumab, and conclude with a discussion on the available evidence and likely directions of the field. EXPERT OPINION Systemic immunotherapy can serve to enhance postoperative therapies for muscle-invasive bladder UC, as exemplified by the recent approval of nivolumab. Further research will serve to define optimal immunotherapy timing and combinations with other systemic therapies, as well as identify predictive biomarkers to allow effective tailoring of therapy for each patient.

Abstract
OBJECTIVES To analyze the impact of neoadjuvant chemotherapy on survival and recurrence patterns in muscle-invasive bladder cancer after robot-assisted radical cystectomy. MATERIALS AND METHODS The International Robotic Cystectomy Consortium database was reviewed to identify patients who underwent robot-assisted radical cystectomy for muscle-invasive bladder cancer between 2002 and 2019. Survival outcomes, response rates, and recurrence patterns were compared between patients who received neoadjuvant chemotherapy and those who did not. Survival distributions were estimated using Kaplan-Meier analyses and compared using the log-rank test. RESULTS A total of 1370 patients with muscle-invasive bladder cancer were identified, of whom 353 (26%) received neoadjuvant chemotherapy. After a median follow-up of 27 months, neoadjuvant chemotherapy recipients had higher 3-year overall survival (74% vs 57%; log-rank P < 0.01), 3-year cancer-specific survival (83% vs 73%; log-rank P = 0.03), and 3-year relapse-free survival (64% vs 48%; log-rank P < 0.01). Neoadjuvant chemotherapy was a predictor of higher overall survival, cancer-specific survival, and relapse-free survival in univariate but not multivariate analysis. Pathological downstaging (46% vs 23%; P < 0.01), complete responses (24% vs 8%; P < 0.01), and margin negativity (95% vs 91%; P < 0.01) at robot-assisted radical cystectomy were more common in the neoadjuvant chemotherapy group. Neoadjuvant chemotherapy recipients had lower distant (15% vs 22%; P < 0.01) but similar locoregional (12% vs 13%; P = 0.93) recurrence rates. CONCLUSIONS In this analysis from a large international database, patients with muscle-invasive bladder cancer who received neoadjuvant chemotherapy before robot-assisted radical cystectomy had higher rates of survival, pathological downstaging, and margin-negative resections. They also experienced fewer distant recurrences.

Abstract
Urothelial carcinoma of the bladder (UCB) is a very heterogeneous disease and divided into invasive and non-invasive disease. In non-muscle-invasive bladder cancer (NMIBC), recurrence after transurethral resection or instillation-therapy, and progression to invasive disease are issues of concern. In muscle-invasive bladder cancer (MIBC), systemic recurrence after radical treatment is a pressing problem, as the available therapies in this setting are of limited efficacy. For both entities there are only few clinicopathological prognostic biomarkers to identify subgroups at risk to aid in decision making to whom to offer early radical cystectomy in case of NMIBC or neoadjuvant/adjuvant chemotherapy in case of MIBC to improve outcomes. Despite advances in surgery and intravesical therapy, up to 30% of NMIBC-patients suffer progression to MIBC. After cystectomy around 50% of MIBC patients suffer local or systemic recurrence and subsequently succumb to the disease. Standard features, like pathological staging and grading, are not sufficient to identify patients at risk beyond doubt. Recent advances in molecular diagnostics in combination with standard pathological features could be used to improve risk stratification of patients, guide treatment plans and ultimately improve outcomes. Immunohistochemical (IHC) analysis can detect altered regulatory pathway-products. Until now a plethora of prognostic IHC-biomarkers has been reported on in UCB, but only few have been validated and no biomarker is in routine use or recommended by guidelines. In this review we discuss the prognostic potential of the most promising IHC-biomarkers in NMIBC and MIBC with a focus on prognostication of recurrence and stage progression in NMIBC as well as recurrence-free, cancer-specific and overall survival in MIBC.

Abstract
Introduction: Bladder cancer is the 9th most common cancer in the world and the 4th and 8th most common cancer diagnosed in men in the United States and United Kingdom respectively. The standard of care for the treatment of MIBC is radical cystectomy. Bladder preserving treatment approaches are emerging for select patients and should be considered strongly in patients who decline a radical cystectomy.Areas covered: In this review we look at the European and American recommended guidelines, the current standard of care, bladder-preserving options in MIBC, trimodal therapy and discuss future developments in the identification of molecular biomarkers that can predict therapeutic outcomes.Expert opinion: We strongly advocate bladder preservation for the right patient with strict criteria for enrolling patients in bladder preservation. The development of a specialized bladder cancer clinic could facilitate the selection of patients to be offered trimodal therapy. We believe that the future of bladder cancer will involve individualized care plans based upon clinical, radiological, endoscopic and molecular assessments.

Abstract
Background: Bladder cancer is a common malignancy that affects the human urinary tract. Muscle-invasive bladder cancer (MIBC) is aggressive and has poor prognosis. Previous studies have reported that the tumor-infiltrating lymphocytes (TILs) were associated with MIBC outcome; however, inconsistency remains and mRNA level TIL markers’ prognostic significance in MIBC is unclear. Materials and methods: In the present study, we reanalyzed data from four public datasets (the Cancer Genome Atlas for investigation; and CIT, GSE5287, and GSE31684 for validation) to examine the prognostic significance of CD3D, CD4, CD8A, CD3D/CD4 and CD3D/CD8A in MIBC. Results: We found that the CD3D/CD4 ratio was a stable independent prognostic factor in MIBC (beta = −0.87, P = 0.025); high CD3D/CD4 ratio predicted better survival in MIBC, and the power of this association was much stronger in basal-squamous tumors (beta = −4.73, P = 2.67E-06). We also noted that the CD4 expression was significantly higher than CD3D (P < 0.05), indicating the presence of CD3−CD4+ cells which could be immune-suppressing. Conclusion: The CD3D/CD4 ratio can be viewed as a prognostic marker and a rough measurement for the interaction between immune-effecting CD3+ TILs and immune-suppressing CD3−CD4+ cells in MIBC, and this interaction may play a particularly important role in anti-cancer immunity in basal-squamous tumors as it has a very strong association with survival in this subtype, and may be used to select potential responders to immunotherapy.

Abstract
Background Studies of survival comparing radical cystectomy (RC) and radiotherapy for muscle‐invasive bladder cancer have provided inconsistent results and have methodological limitations. The aim of the study was to investigate risk of death after radiotherapy as compared to RC. Methods We selected patients with muscle‐invasive urothelial carcinoma without distant metastases, treated with radiotherapy or RC from 1997 to 2014 in the Bladder Cancer Data Base Sweden (BladderBaSe) and estimated absolute and relative risk of bladder cancer death and all‐cause death. In a group of patients, theoretically eligible for a trial comparing radiotherapy and RC, we calculated risk difference in an instrumental variable analysis. We have not investigated chemoradiotherapy as this treatment was not used in the study time period. Results The study included 3 309 patients, of those 17% were treated with radiotherapy and 83% with RC. Patients treated with radiotherapy were older, had more advanced comorbidity, and had a higher risk of death as compared to patients treated with RC (relative risks of 1.5‐1.6). In the “trial population,” all‐cause death risk difference was 6 per 100 patients lower after radiotherapy at 5 years of follow‐up, 95% confidence interval −41 to 29. Conclusion(s) Patient selection between the treatments make it difficult to evaluate results from conventionally adjusted and propensity‐score matched survival analysis. When taking into account unmeasured confounding by instrumental variable analysis, no differences in survival was found between the treatments for a selected group of patients. Further clinical studies are needed to characterize this group of patients, which can serve as a basis for future comparison studies for treatment recommendations.

Abstract
OBJECTIVE To determine whether the recovery window (RW) between neoadjuvant chemotherapy (NAC) and radical cystectomy (RC) affects 90-day postoperative morbidity and incidence of lymph node metastasis. PATIENTS AND METHODS We reviewed patients treated with NAC and RC from 1995 to 2013 for ≤cT4 N0 M0 bladder cancer. The association of the RW with 90-day perioperative morbidity and lymph node metastasis was determined. Generalised linear models were used to determine predictors of each endpoint. Patients were stratified into four RWs by 21-day intervals (18-42; 43-63; 64-84; and ≥85 days) from last day of NAC to RC. RESULTS We evaluated 306 patients with RW information during the study period. The median (range) RW was 46 (18-199) days. There was no difference in overall morbidity, re-admission, or major complication rates amongst the four RWs. In the multivariable analysis extravesical disease was an independent predictor of overall morbidity (odds ratio [OR] 1.95, 95% confidence interval [CI] 1.16-3.26; P = 0.011). Age (OR 1.05, 95% CI: 1.02-1.09; P = 0.004), and surgical duration ≥7 h (OR 2.87, 95% CI: 1.52-5.42; P = 0.001) were independent predictors of major complications. Only surgical duration ≥7 h was a predictor of re-admission (OR 2.24; 95% CI: 1.26-3.98; P = 0.006). A RW of ≥85 days had the highest incidence of node-positive disease (pN+; 40%). In a separate multivariable model that included clinical predictors for pN+, a RW of ≥85 days was an independent predictor of nodal metastasis (OR 2.92, 95% CI: 1.20-7.09; P = 0.018). CONCLUSION Patients treated with NAC for bladder cancer can undergo RC between 18 and 84 days (2.5-12 weeks) after NAC with no difference in the risk of perioperative morbidity. Delaying surgery beyond 12 weeks was associated with a significant risk of lymph node metastasis.

Abstract
Although adjuvant chemotherapy (ACH) is widely used in clinical practice for the management of muscle-invasive bladder cancer (MIBC), a consensus has yet to be established on which ACH regimen is the most effective for improving postoperative survival. In this study, we aimed to systematically assess the optimal ACH regimen for improving survival outcomes in patients treated with radical cystectomy (RC) for MIBC. A comprehensive literature search was conducted in the PubMed, Embase, and the Cochrane Library databases for all articles published until December 2016 in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. The study end-points were progression-free survival (PFS) and overall survival (OS). A direct pairwise meta-analysis was conducted by pooling the studies that compared RC with ACH and RC alone, and the results are presented as a pooled hazard ratio (HR) with a 95% confidence interval (CI). A Bayesian network meta-analysis was adopted for indirect comparisons among various ACH regimens, and the outcomes are presented as HRs with 95% credible intervals (CrI). The eleven randomized controlled trials ultimately selected for the current analysis comprised of 1,546 patients with 49 to 327 subjects per study. Based on the pairwise meta-analysis, the use of ACH showed significantly better PFS (HR, 0.64; 95% CI, 0.49–0.85) and OS (HR, 0.79; 95% CI, 0.68–0.92) than RC alone. In the network meta-analysis, the gemcitabine/cisplatin/paclitaxel (GCP) combination was the only ACH regimen associated with significant improvement in both the PFS (HR, 0.38; 95% CrI, 0.25–0.58) and OS (HR, 0.38; 95% CrI 0.22–0.65). ACH following RC for MIBC may therefore contribute to improved PFS and OS. In particular, the GCP combination may be the optimal ACH regimen for improving postoperative survival outcomes. Additional well-designed, large scale, prospective, randomized trials are still required to establish the optimal ACH regimen in MIBC patients.

Abstract
Bladder cancer (BC) is a frequent type of carcinoma with an estimated incidence of approximately 100,000 men and women each year in the European Union (EU) with an associated mortality of 30,000 of these patients. In more than 70% the disease is diagnosed in a non-muscle invasive stage with the chance of minimally invasive, local treatment only, which might be required repetitively due to high rate of recurrence. In contrast, muscle invasive or metastatic stages need multimodal treatment strategies including surgical treatment and chemotherapy (CTX) in neoadjuvant (NAC), adjuvant, or palliative settings. Therapy recommendations and guidelines mainly refer to the most common histological type of BC, pure urothelial carcinoma (UC). However, BC can be classified as urothelial and non-UC. Non-urothelial BC and variants of UC account for up to 25% of all BCs. Further discrimination can be made into epithelial and non-epithelial non-UC. Most of the non-UCs are of epithelial origin (approximately 90%) including squamous-cell carcinoma, adenocarcinoma and small-cell carcinoma. Non-epithelial tumors are rare and include variants as sarcoma, carcinosarcoma, paraganglioma, melanoma and lymphoma. Even though it is unclear whether the prognosis of non-urothelial cancer truly differs from that of UC, there is evidence that additional variant histology might prognosticate an impaired prognosis. Accordingly, aggressive behavior and often advanced stages at primary presentation are frequently observed in non-UC arguing for radical and sometimes different treatment strategies as compared to pure UC. This review aims to summarize the available data for the most common histological variants of non-urothelial BC.

Abstract
AIM Invasive urothelial carcinoma of the bladder (UCB) is characterized by alterations in cell-cycle regulatory pathways. Defects in the expression of cyclin D1, a key cell-cycle regulator, have been implicated in progression of various types of cancer. In the present study, we investigated whether cyclin D1 expression is associated with clinicopathological parameters and whether it has any potential prognostic value in determining risk of UCB recurrence. PATIENTS AND METHODS Tissue microarrays containing bladder cancer specimens (n=212) and adjacent normal bladder tissues (n=131) were immunostained using an antibody against cyclin D1. The association between cyclin D1 and clinicopathological parameters including stage, lymph node metastasis, and disease-free survival, were evaluated. Cyclin D1 mRNA expression data from human normal bladder (n=14) and cancer specimens (n=28) were extracted from the public Oncomine database. RESULTS Cyclin D1 mRNA and protein expression were significantly higher in UCB compared to adjacent non-malignant bladder tissue (for mRNA p=0.003, for protein p=0.001). Cyclin D1 protein expression was significantly higher in non-invasive tumors than in muscle-invasive UCB (p=0.016). Among patients with muscle-invasive UCB, increased cyclin D1 expression in tumor cells significantly correlated with lymph node metastasis (p<0.001), and there was a trend of cyclin D1 together with lymph node positivity to be associated with disease recurrence (p=0.678). Loss of nuclear cyclin D1 expression in tumor cells was likewise significantly associated with the presence of lymph node metastasis (p<0.001). CONCLUSION Altered expression of cyclin D1 is associated with lymph node metastasis and risk of UCB recurrence. Cyclin D1 expression may therefore have clinical value as a prognostic marker and potential therapeutic target.
