Abstract
BACKGROUND Non-muscle invasive bladder cancer can be controlled by transurethral resection of bladder (TURB), but suffers from frequent recurrences in 60-70% of cases. Although, recurrence interval after TURB influences treatment course and prognosis, its implication and risk factors have not been fully elucidated. We evaluated the risk factors of early (within 1 yr) and late (after 1 yr) recurrence of pTa bladder cancer and clinical significance of recurrence interval on disease progression and overall survival. METHODS In this study, pTa bladder cancer patients enrolled in prospective patient registry system of Seoul National University, SUPER-UC, were retrospectively examined to determine the clinical risk factors for recurrence and its significance regarding to recurrence interval. A total of 1067 bladder cancer patients who underwent TURB between March 20 and June 2021 were included and classified into three groups of no recurrence, early, or late recurrence to be comparatively analyzed. RESULTS Early recurrence was associated with poorer cystectomy-free survival and overall survival than late recurrence. Risk factors for early recurrence included a high number of previous TURB, tumor multiplicity, tumor location, tumor shape, incompleteness of TURB, and high tumor grade. Otherwise, late recurrence was associated with low-grade tumors with insufficient TURB depth. CONCLUSION Patients with risk factors for early recurrence should be closely followed up with special cautions.

Apparent Diffusion Coefficient Value can Predict Poor Bacillus Calmette-Guérin Responders in T1HG/NMIBC: Prospective Cohort Study. Clin Genitourin Cancer 2021; 19:e248-e254. [PMID: 33839041 DOI: 10.1016/j.clgc.2021.03.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2020] [Revised: 02/19/2021] [Accepted: 03/03/2021] [Indexed: 11/20/2022]
Abstract
BACKGROUND Prediction of recurrence and progression and the choice of type of management are largely based on stage and grade; however, these prognostic features are limited in the prediction of clinical outcomes. The objective was to investigate the relation between the apparent diffusion coefficient (ADC) value and recurrence and progression of T1G3 of urothelial carcinoma after transurethral resection of the bladder tumor (TURBT) and Bacillus Calmette-Guérin instillation. MATERIALS AND METHODS This prospective study included 65 patients with single bladder mass T1G3 less than 3 cm without carcinoma in situ or lymphovascular invasion. Mean ADC values of the tumors were compared between patients with and without recurrence and progression following TURBT. The relation of ADC value and other factors were determined by univariate and multivariate analyses. The following tests were used to test differences for significance: difference and association of qualitative variable by χ2 test; differences between quantitative independent groups by t-test or Mann-Whitney U test; survival by Kaplan-Meier; Cox regression (or Cox proportional hazards model) was used to analyze the effect of several risk factors on time until event (recurrence and progression); correlation by Pearson or Spearman, and we calculated the most suitable cutoff and validity by receiver operating characteristic curve. RESULTS In relation to recurrence, smoking, nonpapillary shape and higher size, and lower ADC were significant predictors for recurrence. In relation to progression, female sex, nonpapillary shape, and lower ADC were significant predictors for progression. Multivariate analysis showed that ADC < 1.09 was the only significant independent predictors for recurrence. Also, it showed that ADC < 0.98 was the only significant independent predictors for progression. CONCLUSION Low ADC value group of T1G3 bladder cancer showed significant recurrence and progression than high ADC value group of T1G3 bladder cancer. ADC value in conjunction with other risk stratifications will have a promising role in stratifying patients with T1G3 who need to proceed to early radical cystectomy versus conservative treatment.

[PMID: 32047553 PMCID: PMC6995372 DOI: 10.7150/jca.35710] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2019] [Accepted: 11/22/2019] [Indexed: 12/20/2022] Open
Abstract
The purpose of our study is to elucidate the expression of lncRNA00518 (lnc00518) in the bladder cancer, and its potential mechanism in regulating the development of bladder cancer. The expression of lnc00518 in bladder cancer tissues and cells was examined by qRT-PCR. Correlation between lnc00518 expression with clinicopathologic characteristics and prognosis of bladder cancer patients was analyzed. In vitro effects of lnc00518 on the cellular behaviors of bladder cancer cells were explored. Moreover, in vivo effect of lnc00518 was evaluated by subcutaneous tumorigenesis in nude mice. The possible miRNA targets of lnc00518 were predicted by bioinformatics and further confirmed by dual-luciferase reporter gene assay, RIP and rescue experiments. Lnc00518 was highly expressed in bladder cancer tissues and cells. Lnc00518 expression was correlated with TNM staging and histological grade of bladder cancer. Besides, the overall survival was lower in bladder cancer patients with high expression of lnc00518 relative to those with low expression. Overexpression of lnc00518 enhanced proliferative, invasive, migratory potentials and clonality, but shortened G0/G1 phase of bladder cancer cells. Lnc00518 knockdown obtained the opposite trends. In vivo experiments revealed that lnc00518 knockdown inhibited subcutaneous tumorigenesis in nude mice. QRT-PCR results indicated that lnc00518 expression was negatively correlated with miRNA-101 expression in bladder cancer cells. Through dual-luciferase reporter gene assay and RIP, we confirmed the binding between lnc00518 and miRNA-101. Furthermore, EZH2 was verified to be the target of miRNA-101. MiRNA-101 knockdown reversed the inhibitory roles of lnc00518 knockdown in proliferative, migratory and invasive potentials of bladder cancer cells. Lnc00518 is highly expressed in bladder cancer and can be served as a predictor of poor prognosis. Lnc00518 promotes the proliferative, invasive and migratory potentials of bladder cancer by upregulating EZH2 via competitively binding to miRNA-101.

Abstract
Bladder cancer (BC) is a complex disease and could be classified into nonmuscle‐invasive BC (NMIBC) or muscle‐invasive BC (MIBC) subtypes according to the distinct genetic background and clinical prognosis. Until now, the golden standard and confirmed diagnosis of BC is cystoscopy and the major problems of BC are the high rate of recurrence and high costs in the clinic. Recent molecular and genetic studies have provided perspectives on the novel biomarkers and potential therapeutic targets of BC. In this article, we provided an overview of the traditional diagnostic approaches of BC, and introduced some new imaging, endoscopic, and immunological diagnostic technology in the accurate diagnosis of BC. Meanwhile, the minimally invasive precision treatment technique, immunotherapy, chemotherapy, gene therapy, and targeted therapy of BC were also included. Here, we will overview the diagnosis and therapy methods of BC used in clinical practice, focusing on their specificity, efficiency, and safety. On the basis of the discussion of the benefits of precision medicine in BC, we will also discuss the challenges and limitations facing the non‐invasive methods of diagnosis and precision therapy of BC. The molecularly targeted and immunotherapeutic approaches, and gene therapy methods to BC treatment improved the prognosis and overall survival of BC patients.

Abstract
Therapeutics that block kinases, transcriptional modifiers, immune checkpoints and other biological vulnerabilities are transforming cancer treatment. As a result, many patients achieve dramatic responses, including complete radiographical or pathological remission, yet retain minimal residual disease (MRD), which results in relapse. New functional approaches can characterize clonal heterogeneity and predict therapeutic sensitivity of MRD at a single-cell level. Preliminary evidence suggests that iterative detection, profiling and targeting of MRD would meaningfully improve outcomes and may even lead to cure.

Abstract
OBJECTIVE Checkpoint inhibitors have rapidly become a standard treatment option for metastatic urothelial carcinoma. A wave of enthusiasm for these drugs has pushed them also into the setting of localized bladder cancer, including both non-muscle-invasive bladder cancer (NMIBC) and muscle-invasive disease bladder cancer (MIBC). Here, we aimed to review the emerging role of checkpoint inhibition in localized bladder cancer. METHODS We reviewed the current treatment landscape for both NMIBC and MIBC and established a significant unmet clinical need for novel therapies. We have compiled the evidence that supports the investigation of checkpoint blockade in localized bladder cancer and have reviewed the corresponding clinical trial׳s landscape. RESULTS The success of checkpoint inhibitors in metastatic bladder cancer offers the most compelling rationale for testing checkpoint blockade in localized disease. The established benefit of intravesical Bacillus Calmette-Guérin provides precedent for immune therapy in bladder cancer. Immune dysfunction has been described in bladder cancer, and we know that checkpoint molecules are expressed in these tumors. Furthermore, the high neoantigen burden of bladder cancer and results from preclinical studies suggest that checkpoint blockade deserves testing in earlier stage disease. Multiple trials are either planned or underway in almost all bladder cancer disease states. CONCLUSION Ongoing trials would determine in the next several years whether checkpoint inhibitors can have a similar effect in localized disease as they have had in metastatic bladder cancer. They would also determine if patients with earlier disease would tolerate the toxicity of systemic therapy. The future holds promise for predictive biomarkers to guide individualized use of these agents and for effective combination therapies to overcome resistances.
