Carcinoma Of The Bladder

Abstract This systematic review and meta-analysis aimed to assess the prognostic value of preoperative hematologic biomarkers in patients with urothelial carcinoma of the bladder treated with radical cystectomy. PUBMED, Web of Science, Cochrane Library, and Scopus databases were searched in September 2019 according to the Preferred Reporting Items for Systematic Review and Meta-analysis statement. Studies were deemed eligible if they compared cancer-specific survival in patients with urothelial carcinoma of the bladder with and without pretreatment laboratoryabnormalities. Formal meta-analyses were performed for this outcome. The systematic review identified 36 studies with 23,632 patients, of these, 32 studies with 22,224 patients were eligible for the meta-analysis. Several preoperative hematologic biomarkers were significantly associated with cancer-specific survival as follows: neutrophil − lymphocyte ratio (pooled hazard ratio [HR]: 1.20, 95% confidence interval [CI]: 1.11–1.29), hemoglobin (pooled HR: 0.87, 95% CI 0.82–0.94), C-reactive protein (pooled HR: 1.44, 95% CI 1.26–1.66), De Ritis ratio (pooled HR: 2.18, 95% CI 1.37–3.48), white blood cell count (pooled HR: 1.05, 95% CI 1.02–1.07), and albumin-globulin ratio (pooled HR: 0.26, 95% CI 0.14–0.48). Several pretreatment laboratory abnormalities in patients with urothelial carcinoma of the bladder were associated with cancer-specific mortality. Therefore, it might be useful to incorporate such hematologic biomarkers into prognostic tools for urothelial carcinoma of the bladder. However, given the study limitations including heterogeneity and retrospective nature of the primary data, the conclusions should be interpreted with caution.

Carcinoma Of The Bladder

Abstract Background A systematic review and meta-analysis was performed to compare the clinicopathological features and survival outcomes between sarcomatoid variant (SV)-urothelial carcinoma of the bladder (UCB) and conventional UCB (C-UCB). Methods A comprehensive search of PubMed, Embase, and Cochrane Library was performed. Endpoints included clinicopathological features and survival outcomes (overall survival [OS], cancer-specific survival [CSS], and progression-free survival [PFS]). The survival benefits of neoadjuvant chemotherapy (NAC) or adjuvant chemotherapy (AC) for SV-UCB also have been studied. Results A total of 8 observational studies were included. Patients with SV-UCB had a higher rate of ≥ stage pT3 (odds ratio [OR], 2.06; 95% confidence interval [CI], 1.64–2.59; p < 0.001) and a lower rate of concomitant carcinoma in situ (OR, 0.25; 95% CI, 0.09–0.72; p = 0.010). The other clinicopathological variables were similar between SV-UCB and C-UCB. With unadjusted data, patients with SV-UCB had a significant inferior OS (HR, 1.24; 95% CI, 1.07–1.44; p = 0.004) and CSS (HR, 2.08; 95% CI, 1.63–2.66; p < 0.001). However, after adjusted, SV-UCB had worse OS (HR, 1.41; 95% CI, 0.95–2.08; p = 0.090) and CSS (HR, 1.54; 95% CI, 0.95–2.52; p = 0.080) approaching the borderline of significance. For SV-UCB, NAC (HR, 0.73; 95% CI, 0.51–1.05; p = 0.090) and AC (HR, 0.88; 95% CI, 0.66–1.17; p = 0.370) seemed to have no benefit on OS. Conclusions Compared to C-UCB, SV-UCB was associated with more advanced disease and more inferior OS and CSS. NAC and AC had no survival benefit for SV-UCB.

Background: The clinical evidence of body mass index (BMI) for survival has increased in urothelial carcinoma (UC). This study aimed to investigate the prognostic value of BMI on the oncologic outcomes of patients with UC after surgery. Methods: The systematic review and meta-analysis was performed using Pubmed, Embase and Cochrane Library. We collected hazard ratio (HR) and 95% confidence interval (CI) on cancer specific survival (CSS), overall survival (OS) and recurrence-free survival (RFS) from the studies including upper tract urothelial carcinoma (UTUC) and urothelial carcinoma of bladder (UCB). Results: A total of 13 studies comprising over 12,200 patients were enrolled in the quantitative synthesis. Compared with normal weight, overweight was associated with better CSS (HR = 0.87, 95% CI: 0.79-0.95) and RFS (HR = 0.86, 95% CI: 0.78-0.96). Meanwhile, we found that obese patients had worse CSS (HR = 1.14, 95%CI: 1.03-1.26), OS (HR = 1.31, 95% CI: 1.19-1.44) and RFS (HR = 1.24, 95% CI: 1.12-1.37). We observed that underweight was associated with inferior CSS (HR = 1.87, 95% CI: 1.54-2.26) in UTUC patients. Conclusions: Overweight was a protective factor for patients with UC after surgery, while obesity and underweight predicted unfavorable survival. Individual BMI may be considered for prognostication after surgeries and patient stratification for clinical trials.

325 Background: Prognosis of the patients with urothelial carcinoma of the bladder (UCB) who developed recurrence after radical cystectomy (RC) is generally poor, but can be variable. We previously showed that shorter time to recurrence (TTR) after RC, presence of symptoms on recurrence, more than one metastatic sites (organs), high serum C-reactive protein (CRP) level were associated with decreased survival in those patients, and proposed a model to stratify patients into 3 separate risk groups (Nakagawa et al. J Urol. 2013; 189:1275). The aim of this study was to evaluate the prognostic value of this model in a multi-institutional cohort of patients. Methods: We identified 267 patients who experienced disease recurrence after RC for UCB from 9 academic and community hospitals. Patients were categorized into three groups based on the presence of four risk factors, TTR of <1 year, presence of symptoms on recurrence, more than one metastatic sites (organs), and CRP level of ≥0.5 mg/dl: the favourable risk group included patients with none or one of these risk factors; the intermediate risk group with 2 risk factors; and those with 3 or 4 risk factors were assigned to the poor risk group. Results: Overall, median survival time (MST) of the entire cohort was 8.3 months (95%CI, 6.4-9.1). Two hundred and nineteen patients died of their disease with a median survival of 5.9 months. In a multivariate analysis, all of the 4 risk factors were statistically significant for the cancer-specific survival. Sixty-five (27.4%), 84 (35.4%), and 88 (37.1%) patients were in the favorable, intermediate and poor risk group, respectively. Thirty patients were excluded because CRP value was not obtained. MSTs of the patients in the favorable, intermediate and poor risk group were 22.2 (95% CI 16.1-28.3), 7.6 (95% CI 6.3-9.5), and 3.6 (95% CI 2.6-4.4) months, respectively, and the difference was statistically significant (p<0.001, log-rank test). Conclusions: We confirmed the prognostic value of our previous criteria based on the four variables in patients with recurrence after RC for UCB. This criteria would help in patient counseling and clinical trial design.

Abstract Background: Tumor-infiltrating lymphocytes (TILs) in the tumor microenvironment are associated with different prognosis in various malignancies. However, their prognostic impact remains controversial in urothelial carcinoma of bladder (UCB). In this systematic review and meta-analysis, we aimed to investigate the prognostic value of TILs in UCB patients.Methods: A systematic review and meta-analysis was performed using Pubmed, Embase and Cochrane Library. Studies were eligible if they investigated the prognostic value of CD3+, CD4+, CD8+, Foxp3+ lymphocytes or TILs in UCB patients, by time-to-event survival analysis. All studies were appraised for risk of bias using the Quality and Prognosis Studies (QUIPS) criteria. Hazard rations (HRs) with their 95% confidence interval (CIs) from each study were used to generate pooled HRs. Results: A total of 14 studies assessing the impact of TILs on prognostic outcomes in UCB patients were included in final analysis. The pooled analysis indicated a favorable role of CD3+ TILs (HR 0.74 (95% CI 0.62-0.88) for overall survival) and CD8+ TILs (HR 0.46 (95% CI 0.28-0.74) for OS) in the clinical outcomes of UCB, while Foxp3+ TILs were associated with worse survival (HR 2.21 (95% CI 1.47-3.32) for recurrence-free survival). Conclusions: This systematic review and meta-analysis confirmed the favorable prognostic impact of CD3+ and CD8+ tumor-infiltrating T cells in UCB patients and found the association between Foxp3+ TILs and worse survival. Future studies using large cohorts and standardized methodology with regard to tumor subsites, stages and treatment modalities are needed to incorporate TILs with clinical practice.

IntroductionThere is growing evidence of a higher than expected prevalence of retinopathy in prediabetes. This paper presents the protocol of a systematic review and meta-analysis of retinopathy in prediabetes. The aim of the review is to estimate the prevalence of retinopathy in prediabetes and to summarise the current data.Methods and analysisThis protocol is developed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) guidelines. A comprehensive electronic bibliographic search will be conducted in MEDLINE, EMBASE, Web of Science, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Google Scholar and the Cochrane Library. Eligible studies will report prevalence data for retinopathy on fundus photography in adults with prediabetes. No time restrictions will be placed on the date of publication. Screening for eligible studies and data extraction will be conducted by two reviewers independently, using predefined inclusion criteria and prepiloted data extraction forms. Disagreements between the reviewers will be resolved by discussion, and if required, a third (senior) reviewer will arbitrate.The primary outcome is the prevalence of any standard features of diabetic retinopathy (DR) on fundus photography, as per International Clinical Diabetic Retinopathy Severity Scale (ICDRSS) classification. Secondary outcomes are the prevalence of (1) any retinal microvascular abnormalities on fundus photography that are not standard features of DR as per ICDRSS classification and (2) any macular microvascular abnormalities on fundus photography, including but not limited to the presence of macular exudates, microaneurysms and haemorrhages. Risk of bias for included studies will be assessed using a validated risk of bias tool for prevalence studies. Pooled estimates for the prespecified outcomes of interest will be calculated using random effects meta-analytic techniques. Heterogeneity will be assessed using the I2 statistic.Ethics and disseminationEthical approval is not required as this is a protocol for a systematic review and no primary data are to be collected. Findings will be disseminated through peer-reviewed publications and presentations at national and international meetings including Diabetes UK, European Association for the Study of Diabetes, American Diabetes Association and International Diabetes Federation conferences.PROSPERO registration numberCRD42020184820.

BACKGROUND: The optimal management of non-invasive (mucosal and/or ductal) urothelial carcinoma of the prostate remains elusive and there is a paucity of data to guide treatment. OBJECTIVE: Our objective was to systematically review and synthesize treatment responses to conservative management of non-invasive prostatic urothelial carcinoma using intravesical therapy. METHODS: A systematic literature search using MEDLINE, EMBASE, Cochrane Library, SCOPUS, and Web of Science databases from inception to November 2019 was performed. Risk of bias assessment was performed using the Newcastle-Ottawa scale for non-randomised studies. Pooled estimates of complete response in the bladder and prostate and prostate only were performed using a random effects model. Pre-specified subgroup analyses were generated to assess differences in complete responses for: BCG therapy vs other agents, ductal vs mucosal involvement, CIS vs papillary tumors and TURP vs no TURP. RESULTS: Nine studies including 175 patients were identified for inclusion in the systematic review and meta-analysis. All were retrospective case series and most evaluated response to BCG therapy. The pooled global complete response rate for intravesical therapy was 60%(95%CI: 0.48, 0.72), and for prostate 88%(95%CI: 0.81, 0.96). Pre-specified analyses did not demonstrate statistically significant differences between subgroups of interest. CONCLUSIONS: Management of non-invasive prostatic urothelial carcinoma using intravesical therapy yields satisfactory results. Caution should be taken in treating patients with papillary tumors and ductal involvement, as data for these populations is limited. TURP may not improve efficacy, but is required for staging. Current recommendations are based on low quality evidence, and further research is warranted.
