Retrospective study of systemic immune-inflammation index in muscle invasive bladder cancer: initial results of single centre

Purposes

We aimed to evaluate the prognostic value of the preoperative systemic immune-inflammation index (SII) in patients who underwent radical cystectomy due to muscle invasive bladder cancer (MIBC).

Methods

We researched our cystectomy database between April 2006 and December 2018. Demographic data, operation and postoperative data were recorded. There were 191 MIBC patients who underwent radical cystectomy. After detailed analyses, preoperative SII was calculated by the formula as “(neutrophil)?×?(platelet)/(lymphocyte)”. Cancer-specific survival (CSS) and overall survival (OS) were examined. The prognostic value of SII was analysed with univariate and multivariate Cox proportional hazards regression models. Receiver operating characteristic (ROC) was used to determine the optimum SII. Significant P was P?<?0.05.

Results

The mean follow-up was 37?±?6.7 months. The mean age of patients was 62.1?±?9 years. The optimal cutoff value of SII was determined as 843 in ROC curve (area under the curve: 0.9; P?<?0.001). The CSS and OS were significantly poor in patients with higher SII level (respectively; P?<?0.001, P?=?0.04). Gender, lymph node involvement, pathologic stage, grade and SII were statistically significant in multivariate Cox proportional hazards regression model for CSS.

Conclusions

Preoperative elevated SII could be an independent prognostic factor in MIBC patients who underwent radical cystectomy. If SII?>?843, CSS might be poor. Our results should be confirmed with randomised-controlled prospectively designed future studies with large cohorts.

Prognostic significance of the Ki67 index and programmed death-ligand 1 expression after radical cystectomy in patients with muscle-invasive bladder cancer

ObjectivesTo investigate the association between Ki67 index and programmed death-ligand 1 (PD-L1) expression in muscle-invasive bladder cancer (MIBC) patients after RC.Materials and MethodsWe retrospectively evaluated 262 MIBC patients treated with RC between April 2004 and April 2020. The impact of Ki67 index and PD-L1 expression on prognosis was evaluated by univariate Cox regression analysis. In addition, a pathomolecular risk score, including Ki67 and PD-L1, was developed to predict prognosis and pathological factors. We also evaluated the link between the Ki67 index and PD-L1 under the IL-6 stimulation in the bladder cancer cell lines of T24 and 5637 cells.ResultsThe median age and follow-up period was 69 years and 52 months, respectively. Ki67 index and PD-L1 expression were significantly associated with tumor recurrence. Univariate Cox regression analysis showed that pT3–4, mixed histology, lymphovascular invasion positive (LVI+), pN+, Ki67-high (>17%), and PD-L1+ were significantly associated with recurrence-free survival (RFS). The pathomolecular risk score was developed using resection margin+ (1 point), mixed histology (1 point), LVI+ (1 point), pN+ (1 point), and Ki67-high (1 point). RFS and overall survival were significantly shorter in patients with higher pathomolecular risk scores (>1) than in those with lower risk scores (≤1). Cell proliferation was significantly increased in the T24 and 5637 cells under the IL-6 stimulation, while PD-L1 expression was not.ConclusionsA significant effect of Ki67-high and PD-L1 expression on poor prognosis was observed in patients with MIBC. Further studies are necessary to elucidate the precise mechanisms of cell proliferation and PD-L1 expression in patients with MIBC.     

Impact of preoperative systemic immune-inflammation Index on oncologic outcomes in bladder cancer patients treated with radical cystectomy

PurposeTo investigate the predictive and prognostic value of the preoperative systemic immune-inflammation index (SII) in patients undergoing radical cystectomy (RC) for clinically non-metastatic urothelial cancer of the bladder (UCB).MethodsOverall, 4,335 patients were included, and the cohort was stratified in two groups according to SII using an optimal cut-off determined by the Youden index. Uni- and multivariable logistic and Cox regression analyses were performed, and the discriminatory ability by adding SII to a reference model based on available clinicopathologic variables was assessed by area under receiver operating characteristics curves (AUC) and concordance-indices. The additional clinical net-benefit was assessed using decision curve analysis (DCA).ResultsHigh SII was observed in 1879 (43%) patients. On multivariable preoperative logistic regression, high SII was associated with lymph node involvement (LNI; P = 0.004), pT3/4 disease (P <0.001), and non-organ confined disease (NOCD; P <0.001) with improvement of AUCs for predicting LNI (P = 0.01) and pT3/4 disease (P = 0.01). On multivariable Cox regression including preoperative available clinicopathologic values, high SII was associated with recurrence-free survival (P = 0.028), cancer-specific survival (P = 0.005), and overall survival (P = 0.006), without improvement of concordance-indices. On DCAs, the inclusion of SII did not meaningfully improve the net-benefit for clinical decision-making in all models.ConclusionHigh preoperative SII is independently associated with pathologic features of aggressive disease and worse survival outcomes. However, it did not improve the discriminatory margin of a prediction model beyond established clinicopathologic features and failed to add clinical benefit for decision making. The implementation of SII as a part of a panel of biomarkers in future studies might improve decision-making.

Comparison of the prognosis of primary vs. progressive muscle invasive bladder cancer after radical cystectomy: Results from a large multicenter study

PurposeTo assess whether progressive and primary muscle invasive bladder cancer (MIBC) have different prognosis after radical cystectomy or not. To date only a few data are available on this topic with conflicting results. Further studies on large cohort are needed to clarify these outcomes that may influence bladder cancer management for these patients.Material and methodsA multicentre retrospective study was conducted on patient treated for MIBC at 5 centres between 2005 and 2015 by radical cystectomy. Patients’ outcomes were compared between patients with primary MIBC vs. progressive MIBC subsequent to a history of non-muscle invasive bladder cancer (NMIBC).ResultsA total of 1197 patients were included. Median (IQ) age was 65 (58–72) years and median follow-up was 65 months. Baseline characteristics were similar between the groups as well as the Tumour pT stage, N status and positive surgical margins. Patients with progressive MIBC had worse overall survival (OS) (hazard ratio [HR] 1.36, [95%CI 1.10–1.76]; P = 0.004), cancer specific survival (CSS) (HR 1.41 [1.13–1.78]; P = 0.002), and recurrence-free survival (RFS) (HR 1.21 [1.01–1.49]; P = 0.05). Pathological stage ≥pT3, positive surgical margins, and positive lymph nodes status (pN+) were also found as predictors of OS, CSS, and RFS.ConclusionsOur results suggest that patient having a progressive BC have a worse prognosis in terms of OS, PFS, and CSS than patient with primary disease. These 2 groups may require different management and patients with high risk NMIBC should be assessed properly to avoid progression and be offered early cystectomy.

Prospective Assessment of Vesical Imaging Reporting and Data System (VI-RADS) and Its Clinical Impact on the Management of High-risk Non–muscle-invasive Bladder Cancer Patients Candidate for Repeated Transurethral Resection

BackgroundVesical Imaging Reporting and Data System (VI-RADS) score is adopted to provide preoperative bladder cancer (BCa) staging. Repeated transurethral resection of bladder tumor (Re-TURBT) is recommended in most of high-risk non–muscle-invasive bladder cancers (HR-NMIBCs) due to possibility of persistent/understaged disease after initial TURBT. No diagnostic tools able to improve patient’s stratification for such recommendation exist.ObjectiveTo (1) prospectively validate VI-RADS for discriminating between NMIBC and muscle-invasive bladder cancer (MIBC) at TURBT, and (2) evaluate the accuracy of VI-RADS for identifying HR-NMIBC patients who could avoid Re-TURBT and detecting those at higher risk for understaging after TURBT.Design, setting, and participantsPatients with BCa suspicion were offered multiparametric magnetic resonance imaging (mpMRI) before TURBT. According to VI-RADS, a cutoff of ≥3 to define MIBC was assumed. TURBT reports were compared with preoperative VI-RADS scores to assess accuracy of mpMRI for discriminating between NMIBC and MIBC. HR-NMIBC Re-TURBT reports were compared with preoperatively recorded VI-RADS scores to assess mpMRI accuracy in predicting Re-TURBT outcomes.InterventionMultiparametric MRI of the bladder before TURBT.Outcome measurements and statistical analysisSensitivity, specificity, positive (PPV) and negative (NPV) predictive values were calculated for mpMRI performance in patients undergoing TURBT and for HR-NMIBC patients candidate for Re-TURBT. Performance of mpMRI was assessed by receiver operating characteristic curve analysis. Ƙ statistics was used to estimate inter- and intrareader variability.Results and limitationsA total of 231 patients were enrolled. Multiparametric MRI showed sensitivity, specificity, PPV, and NPV for discriminating NMIBC from MIBC at initial TURBT of 91.9% (95% confidence interval [CI]: 82.2–97.3), 91.1% (95% CI: 85.8–94.9), 77.5% (95% CI: 65.8–86.7), and 97.1% (95% CI: 93.3–99.1), respectively. The area under the curve (AUC) was 0.94 (95% CI: 0.91–0.97). Among HR-NMIBC patients (n = 114), mpMRI before TURBT showed sensitivity, specificity, PPV, and NPV of 85% (95% CI: 62.1–96.8), 93.6% (95% CI: 86.6–97.6), 74.5% (95% CI: 52.4–90.1), and 96.6% (95% CI: 90.5–99.3) respectively, to identify patients with MIBC at Re-TURBT. The AUC was 0.93 (95% CI: 0.87–0.97).ConclusionsVI-RADS is accurate for discriminating between NMIBC and MIBC. Within HR-NMIBC cases, VI-RADS could, in future, improve the selection of patients who are candidate for Re-TURBT.Patient summaryWe investigated the accuracy of Vesical Imaging Reporting and Data System (VI-RADS) score to asses bladder cancer staging before transurethral resection of bladder tumors, and we explored the performance of VI-RADS score as a future preoperative predictive tool for the selection of high-risk non–muscle-invasive bladder cancer patients who are candidate for undergoing early repeated transurethral resection of the primary tumor site.     

Significance of preoperative butyrylcholinesterase as an independent predictor of survival in patients with muscle-invasive bladder cancer treated with radical cystectomy

ObjectivesButyrylcholinesterase (BChE) is an alpha-glycoprotein found in the nervous system and liver. Its serum level is reduced in many clinical conditions, such as liver damage, inflammation, injury, infection, malnutrition, and malignant disease. In this study, we analyzed the potential prognostic significance of preoperative BChE levels in patients with muscle-invasive bladder cancer (MIBC) undergoing radical cystectomy (RC).Methods and materialsWe retrospectively evaluated 327 patients with MIBC who underwent RC from 1996 to 2013 at a single institution. Serum BChE level was routinely measured before operation in all patients. Covariates included age, gender, preoperative laboratory data (anemia, BChE, lactate dehydrogenase, and C-reactive protein), clinical T (cT) and N stage (cN), tumor grade, and RC with/without neoadjuvant chemotherapy. Univariate and multivariate analyses were performed to identify clinical factors associated with overall survival (OS) and disease-free survival (DFS). Univariate analyses were performed using the Kaplan-Meier and log-rank methods, and the multivariate analysis was performed using a Cox proportional hazard model.ResultsThe median BChE level was 187 U/l (normal range: 168–470 U/l). The median age of the enrolled patients was 69 years, and the median follow-up period was 51 months. The 5-year OS and DFS rates were 69.6% and 69.3%, respectively. The 5-year OS rates were 90.1% and 51.3% in the BChE≥168 and<168 U/l groups, respectively (P<0.001). The 5-year DFS rates were 83.5% and 55.4% in the BChE≥168 and≤167 U/l groups, respectively (P<0.001). In the univariate analysis, BChE, cT, cN, and RC with/without neoadjuvant chemotherapy were significantly associated with both OS and DFS. Multivariate analysis revealed that BChE was the factor most significantly associated with OS, and BChE, cT, and cN were significantly associated with DFS.ConclusionsThis study validated preoperative serum BChE levels as an independent prognostic factor for MIBC after RC.
