Comprehensive pan-cancer single-cell analysis reveals glycolysis-related signatures as predictive biomarkers for immunotherapy response and their role in bladder Cancer.

Glycolysis is a vital metabolic biological process in tumor progression and immune modulation. This study comprehensively investigated the roles of glycolysis in pan-cancer, especially in bladder cancer. Exploration of 34 single-cell RNA sequencing (scRNA-seq) cohorts, eight ICI-treated bulk RNA-seq cohorts, and TCGA bulk pan-cancer RNA-seq cohorts uncovered a Glycolysis.

Leveraging Deep Learning in Real-Time Intelligent Bladder Tumor Detection During Cystoscopy: A Diagnostic Study.

Background: Accurate detection of bladder lesions during cystoscopy is crucial for early tumor diagnosis and recurrence monitoring. However, conventional visual inspection methods have low and inconsistent detection rates. This study aimed to evaluate the effectiveness of the HRNetV2 deep learning model for intelligent bladder lesion detection, focusing on its performance at different image resolutions.

Robot-Assisted Radical Prostatectomy Using the KangDuo Surgical Robot-1500: A Prospective, Multicenter, Single-Arm Clinical Study.

The KangDuo Surgical Robot-1500 (KD-SR-1500) is a newly developed surgical robot. We aim to evaluate the feasibility and efficiency of the KD-SR-1500 system for robot-assisted radical prostatectomy (RARP). This prospective, multicenter, single-arm clinical study was conducted among 18-75-year-old patients with suspected T1-2N0M0 prostate cancer scheduled for RARP.

Anti-PD-1 immunotherapy for the treatment of metastatic urothelial carcinoma in a kidney transplant recipient: a case report.

Background: Immune checkpoint inhibitor (ICI) therapy has been widely investigated in urothelial carcinoma; however, the utility of ICI therapy in the treatment of organ transplant recipients with metastatic urothelial carcinoma (mUC) is unclear. We herein report the first case of a first-line anti-programmed cell death-1 (anti-PD-1) monotherapy for a kidney transplant patient with mUC.

Case Presentation: A 71-year-old woman who received a kidney transplant in 2003 was diagnosed with urothelial carcinoma in 2018.

Feasibility, safety and effectiveness of robot-assisted radical prostatectomy with a new robotic surgical system: a prospective, controlled, randomized clinical trial.

Background: Robot-assisted radical prostatectomy (RARP) gains increasing popularity in the surgical management of prostate cancer (PCa) but is challenged by its prohibitive expense. A domestic robotic system has been developed to address this issue, but data comparing the self-developed robot with the widely used robot is lacking. We performed a randomized clinical trial to compare KD-SR-01 and DaVinci robots in terms of perioperative, short-term oncological and functional outcomes in RARP.

[Retracted] Tetramethylpyrazine inhibits prostate cancer progression by downregulation of forkhead box M1.

Following the publication of this paper, it was drawn to the Editor's attention by a concerned reader that certain of the Transwell invasion assay data shown in Fig. 3B on p. 839 were strikingly similar to data that had already appeared in another article written by different authors at different research institutes [Mao Y, Zhang L, Yuan L, Yan M and He Y: MiR‑218 suppresses cell progression by targeting APC in cervical cancer.

Initial Experience of Robot-Assisted Nephroureterectomy without Intraoperative Repositioning Using a New Robotic Surgical System (KD-SR-01TM).

Background: Robot-assisted nephroureterectomy (RANU) has been more and more applied since 21st century. However, the high cost limits the widespread use of robot system. A relatively low-cost new robotic surgical system (KD-SR-01™) has recently been developed in China.

PD-L1 expression and its correlation with tumor biomarkers in Chinese urothelial bladder cancer.

Data on prevalence of programmed death ligand-1 (PD-L1) expression and its correlation with tumor biomarkers in Chinese patients with muscle-invasive urothelial bladder cancer (MIUBC) are scarce. We investigated the prevalence of PD-L1 expression, PD-L1 expression in tumor cells (TC) and immune cells (IC), and its correlation with tumor biomarkers (CD8+ T cells and tumor mutation burden [TMB]) in Chinese patients with newly diagnosed MIUBC (NCT03433924). Of 248 patients enrolled, 229 with PD-L1 data available were analysed.

The prognostic impact of tumor location in nonmuscle-invasive bladder cancer patients undergoing transurethral resection: insights from a cohort study utilizing Chinese multicenter and SEER registries.

Objective: Most bladder cancers are nonmuscle invasive bladder cancer (NMIBC), and transurethral resection of bladder tumors (TURBT) is the standard treatment. However, postoperative recurrence remains a significant challenge, and the influence of bladder tumor location on prognosis is still unclear. This study aims to investigate how tumor location affects the prognosis of NMIBC patients undergoing TURBT and to identify the optimal surgical approach.

The role of antimicrobial prophylaxis in laparoscopic nephrectomy for renal cell carcinoma.

Background: To investigate the role of antimicrobial prophylaxis in laparoscopic nephrectomy for renal cell carcinoma.

Methods: We retrospectively enrolled 1000 patients who underwent laparoscopic nephrectomy from August 2019 to November 2021 in the Peking Union Medical College Hospital. Patients were divided into group without antimicrobial prophylaxis (n = 444) and group with antimicrobial prophylaxis (n = 556).

Comparison of AirSeal versus conventional insufflation system for retroperitoneal robot-assisted laparoscopic partial nephrectomy: a randomized controlled trial.

Purpose: AirSeal is a valve-less trocar insufflation system which is widely used in robotic urologic surgeries. More evidence is needed concerning the application and cost of AirSeal in retroperitoneal robot-assisted laparoscopic partial nephrectomy.

Methods: We conducted a randomized controlled trial enrolling 62 patients who underwent retroperitoneal robot-assisted laparoscopic partial nephrectomy from February 2022 to February 2023 in the Peking Union Medical College Hospital.

Plural molecular and cellular mechanisms of pore domain encephalopathy.

variants in children with neurodevelopmental impairment are difficult to assess due to their heterogeneity and unclear pathogenic mechanisms. We describe a child with neonatal-onset epilepsy, developmental impairment of intermediate severity, and G256W heterozygosity. Analyzing prior KCNQ2 channel cryoelectron microscopy models revealed G256 as a node of an arch-shaped non-covalent bond network linking S5, the pore turret, and the ion path.

Efficacy and Safety of Disitamab Vedotin in Patients With Human Epidermal Growth Factor Receptor 2-Positive Locally Advanced or Metastatic Urothelial Carcinoma: A Combined Analysis of Two Phase II Clinical Trials.

Purpose: To evaluate the efficacy and safety of disitamab vedotin (DV, RC48-ADC), a novel humanized anti-human epidermal growth factor receptor 2 (HER2) antibody conjugated with monomethyl auristatin E, in patients with HER2-positive locally advanced or metastatic urothelial carcinoma (UC) refractory to standard or regular therapies.

Patients And Methods: The data analyzed and reported are from two phase II, open-label, multicenter, single-arm studies (RC48-C005 and RC48-C009) in patients with HER2-positive (immunohistochemistry 3+ or 2+) locally advanced or metastatic UC who have progressed on at least one previous line of systemic chemotherapy. Patients received DV treatment (2 mg/kg IV infusion, once every 2 weeks).

POLR3G promotes EMT via PI3K/AKT signaling pathway in bladder cancer.

RNA Polymerase III Subunit G (POLR3G) promotes tumorigenesis, metastasis, cancer stemness, and chemoresistance of breast cancer and lung cancer; however, its biological function in bladder cancer (BLCA) remains unclear. Through bioinformatic analyses, we found that POLR3G expression was significantly elevated in BLCA tumor tissues and was associated with decreased survival. Multivariate Cox analysis indicated that POLR3G could serve as an independent prognostic risk factor.

Machine-learning based integrating bulk and single-cell RNA sequencing reveals the SLC38A5-CCL5 signaling as a promising target for clear cell renal cell carcinoma treatment.

Cancer-associated fibroblasts paly critical roles in regulating cancer cell biological properties by intricate and dynamic communication networks. But the mechanism of CAFs in clear cell renal cell carcinoma (ccRCC) is not clear. In our study, we identified CAFs and malignant cells from the integrated scRNA-seq datasets and establish a CAF-derived communication signature based on the highly activated regulons ETS1 and MEF2C.
