Electrical impedance-based tissue classification for bladder tumor differentiation.
Sci Rep

Institute for System Dynamics, University of Stuttgart, Waldburgstr. 19, 70563, Stuttgart, Germany.
Including sensor information in medical interventions aims to support surgeons to decide on subsequent action steps by characterizing tissue intraoperatively. With bladder cancer, an important issue is tumor recurrence because of failure to remove the entire tumor. Impedance measurements can help to classify bladder tissue and give the surgeons an indication on how much tissue to remove.

Purpose: Bladder preservation therapy in combination with atezolizumab and radiation therapy (BPT-ART) trial, which was a multicenter, open-label, single-arm phase II study, showed a promisingly high interim clinical complete response (cCR) rate of 84.4% (38/45). In the present study, we aimed to identify potential tissue biomarkers for achieving cCR via BPT-ART.

Faculty of Medicine, Ain Shams University, Cairo, Egypt.
Aim: To evaluate the role of preoperative neutrophils to lymphocytes ratio (NLR) as a predictor for the response to BCG in patients with non-muscle invasive bladder cancer (NMIBC).
Materials: Nighty six patients with NMIBC were prospectively included in our study. Our study population was classified into two groups, based on pre-operative (NLR) either ⩽ or > 3.
PD-L1 expression in high-risk non-muscle invasive bladder cancer is not a biomarker of response to BCG.

Department of Urology, Erasmus University Medical Center, Erasmus MC Cancer Institute, Dr. Molewaterplein 40, Room Be-304, 3015 GD, Rotterdam, The Netherlands.
Purpose: Up to 50% of high-risk non-muscle invasive bladder cancer (HR-NMIBC) patients fail Bacillus Calmette-Guérin (BCG) treatment, resulting in a high risk of progression and poor clinical outcomes. Biomarkers that predict outcomes after BCG are lacking. The antitumor effects of BCG are driven by a cytotoxic T cell response, which may be controlled by immune checkpoint proteins like Programmed Death Ligand 1 (PD-L1).

Limited research into the tumor immune microenvironment (TIME) for bladder urothelial carcinoma (BUC), particularly the neglect of the intratumoral microbiota, has hindered the development of immunotherapies targeting BUC. Here, we collect 401 patients with BUC with host transcriptome samples and matched tumor microbiome samples from The Cancer Genome Atlas database. Besides, two independent BUC cohorts receiving immunotherapy were obtained.
