Impact of pelvic lymph node dissection on survival outcomes in non-muscle invasive bladder cancer: a multicenter retrospective study.

This multicenter, retrospective study evaluated the impact of pelvic lymph node dissection (PLND) on survival outcomes in non-muscle invasive bladder cancer (NMIBC) patients undergoing radical cystectomy (RC) and identified factors associated with upstaging. A total of 544 NMIBC patients who underwent RC with or without PLND between 2019 and 2024 were analyzed. Survival outcomes, including cancer-specific survival (CSS) and recurrence-free survival (RFS), were compared using Kaplan-Meier analysis and Cox proportional hazards models, while factors associated with upstaging were examined through logistic regression.

Development and validation of a nomogram for predicting prostatic urethral involvement in bladder cancer.

To identify risk factors for prostatic urethral involvement (PUI) in bladder cancer and develop an accurate nomogram prediction model. We retrospectively analyzed 295 male patients with bladder urothelial carcinoma undergoing transurethral prostatic biopsy. Risk factors of PUI in bladder cancer were assessed through univariate and multivariate logistic regression analyses.

Selective apoptosis of tumor-associated platelets boosts the anti-metastatic potency of PD-1 blockade therapy.

Despite the transformative impact of programmed cell death protein-1 (PD-1) blockade therapy on metastatic/advanced solid tumor treatment, its efficacy is hindered by a limited response rate. Platelets play a pivotal role in tumor metastasis by shielding circulating tumor cells and secreting immunosuppressive factors. We here demonstrate that selectively inducing apoptosis in tumor-associated platelets (TAPs) using ABT-737-loaded nanoparticles (cyclic arginine-glycine-aspartate containing peptide-modified ABT-737-loaded nanoparticles [cRGD-NP@A]) enhances the anti-metastatic efficacy of the anti-PD-1 antibody (aPD-1).

Development and validation of a glycolysis-associated gene signature for predicting the prognosis, immune landscape, and drug sensitivity in bladder cancer.

Background: Bladder cancer (BCa) is one of the most common malignancies worldwide, and its prognostication and treatment remains challenging. The fast growth of various cancer cells requires reprogramming of its energy metabolism using aerobic glycolysis as a major energy source. However, the prognostic and therapeutic value of glycolysis-related genes in BCa remains to be determined.

The patients were divided into two groups, a bladder-preserving surgery (BPS) group and a radical cystectomy (RC) group, according to the specific surgical approach used for each patient.

Establishing a Murine Superficial Bladder Cancer Model via an Intravesical Cell Administration Technique.

This study presents an innovative method for establishing an orthotopic murine bladder tumor model with high efficiency and precise tumor localization. After anesthetizing female C57BL/6J mice in a supine position, a 24 G intravenous needle is inserted into the bladder to evacuate its contents. A 34 G dispensing needle is then introduced through the catheter, rotated five times to create a focal injury to the bladder dome mucosa, and subsequently removed.

Targeted Inhibition of Lymphovascular Invasion Formation with CREKA Peptide-Modified Silicasomes to Boost Chemotherapy in Bladder Cancer.

Despite its significant clinical efficacy as a first-line treatment for advanced bladder cancer, cisplatin-based chemotherapy provides a limited benefit for patients with lymphovascular invasion (LVI), which is characterized by the presence of tumor emboli within blood vessels and associated with enhanced cisplatin resistance and metastatic potential. Notably, platelets, a critical component of LVI, hinder the delivery of chemotherapeutic agents to tumors and facilitate metastasis. Consequently, platelet function inhibition holds the potential to disrupt LVI formation, as well as augment the antitumor activity of cisplatin.

The Combination of Sinusoidal Perfusion Enhancement and Apoptosis Inhibition by Riociguat Plus a Galactose-PEGylated Bilirubin Multiplexing Nanomedicine Ameliorates Liver Fibrosis Progression.

Chronic liver injury and continuous wound healing lead to extracellular matrix (ECM) deposition and liver fibrosis. The elevated production of reactive oxygen species (ROS) in the liver leads to the apoptosis of hepatocytes and the activation of hepatic stellate cells (HSCs). In the current study, we describe a combination strategy of sinusoidal perfusion enhancement and apoptosis inhibition enabled by riociguat together with a tailor-designed galactose-PEGylated bilirubin nanomedicine (Sel@GBRNPs).
