Background: PD-L1 represents a crucial immune checkpoint molecule in the tumor microenvironment, identified as a key target for cancer immunotherapy. A correlation between PD-L1 and EMT-related genes expression in various human cancers has been suggested. Methods: By ScreenCell filtration, digital droplet PCR and confocal microscopy analysis, we aimed to investigate the expression of PD-L1 and EMT/invasive genes (TWIST1, ZEB1, VIMENTIN, TIMP2) in circulating tumor cells (CTCs) collected from the blood of non-muscle-invasive bladder cancer (NMIBC) patients, assessing the prognostic value of these biomarkers in the disease. Welchs’ test and Mann–Whitney U test, correlation index, Kaplan–Meier, Univariate and Multivariate Cox hazard proportional analysis were used. Results: Higher PD-L1, TIMP2 and VIM mRNA levels were found in pT1 compared to pTa NMIBC. As evaluated by Kaplan–Meier and Univariate and Multivariate Cox analysis, enhancement of PD-L1, TWIST1 and TIMP2 expression reduces the recurrent free survival in NMIBC patients. Conclusions: High PD-L1, TWIST1 and TIMP2 mRNAs mark the recurrent-NMIBC patients and by reducing the RFS represent negative prognostic biomarkers in these patients.

Abstract Background: Bladder cancer is characterized by its frequent recurrence and progression. Effective treatment strategies need to be based on an accurate risk stratification, in which muscle invasiveness and tumor grade represent the two most important factors. Traditional imaging techniques provide preliminary information about muscle invasiveness but are lacking in terms of accuracy. Although as the gold standard, pathological biopsy is only available after the surgery and cannot be performed longitudinally for long-term surveillance. Methods: In this work, we developed a microfluidic approach that interrogates circulating tumor cells (CTCs) in the peripheral blood of bladder cancer patients to reflect the risk stratification of the disease. Results:In a cohort of 48 bladder cancer patients comprising 33 non-muscle invasive bladder cancer (NMIBC) cases and 15 muscle invasive bladder cancer (MIBC) cases, the CTC count was found to be considerably higher in the MIBC group compared with the NMIBC group (4.67 vs. 1.88 CTCs/3 mL, P=0.019), and was significantly higher in high-grade bladder cancer patients verses low-grade bladder cancer patients (3.69 vs. 1.18 CTCs/3mL, P=0.024). Conclusions: This microfluidic assay of CTCs is believed to be a promising complementary tool for the risk stratification of bladder cancer.Trial registration: This research was conducted under the approval of the Ethics Committee of the First Affiliated Hospital at Zhejiang University School of Medicine with the Registration No. 2015-218.

AbstractIntroduction: 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.

309 Background: Valrubicin was approved in the United States in 1998, removed from the market in 2002 because of manufacturing issues, and reintroduced in 2009. We report the effectiveness and safety of valrubicin, stratified by patient age, from a US multicenter, observational, retrospective study. Methods: Medical records of adults with non–muscle-invasive bladder cancer (NMIBC) who used valrubicin were abstracted between March and September 2011. The median age (75 [range 42–95] years) was the stratification cutoff. Kaplan-Meier analyses were performed for event-free survival (EFS), worsening-free survival (WFS), and progression-free survival (PFS). Results: 113 patients (mean age, 73.7 years) received intravesical valrubicin (median, 6 [range, 2–18] instillations). Median EFS, WFS, and PFS were similar in patients ≤75 vs >75 years old (see Table); 1-year rates were 17.8% vs 15.4%, respectively, for EFS; 16.1% vs 14.3% for WFS; and 80.2% vs 81.4% for PFS. 11 (19%) patients aged ≤75 years vs 4 (7%) aged >75 years underwent radical cystectomy; 28 (48%) vs 28 (51%), respectively, experienced ≥1 local adverse reaction; 3 (5%) vs 4 (7%) experienced ≥1 serious adverse event; and 4 (7%) vs 1 (2%) discontinued as a result. Conclusions: In patients with NMIBC treated with intravesical valrubicin, effectiveness and safety are similar in patients aged ≤75 and >75 years.
