To study the therapeutic effect of nano-dosin-loaded drug system in mouse bladder cancer, a luciferase-labeled mouse bladder cancer cell line and a mouse bladder cancer model were constructed. imaging monitors tumor growth and uses a combination of photothermal, immune, and chemotherapy to treat the mouse model. With doxorubicin as an antitumor drug carrier, the drug loading, drug release, cytotoxicity and behavior in cells of mesoporous nano particle-targeted drug delivery system were studied. The cells were injected into the bladder through the urethra, and the mouse bladder cancer subcutaneous model was treated with gelatin-coated single-walled carbon nanotube-encapsulated mouse granulocytes-macrophage colony-stimulating factor and doxorubicin. In the process of using, the use of near-infrared light for irradiation, thereby achieving the combined effect of photothermal, immune and chemotherapy. The experimental results show that the prepared doxorubicin prodrug delivery system can enhance the targeted therapeutic effect and reduce the toxicity and side effects of the drug. Especially for those cancer cells or tissues with overexpression of folate receptors, it has a better therapeutic effect and provides reference for the treatment of subsequent bladder cancer.

The spatial landscape of cancer hallmarks reveals patterns of tumor ecological dynamics and drug sensitivity.

Tumors are complex ecosystems of interacting cell types. The concept of cancer hallmarks distills this complexity into underlying principles that govern tumor growth. Here, we explore the spatial distribution of cancer hallmarks across 63 primary untreated tumors from 10 cancer types using spatial transcriptomics.

This study aimed to investigate the role of myosteatosis, sarcopenia, and perioperative serum biomarkers as independent predictors of major complications within 180 days following radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC). We retrospectively analyzed of 127 MIBC patients who underwent RC between 2013 and 2023 at a single institution. Preoperative body composition was assessed using CT scans at the L3 vertebral level to measure psoas muscle density (PMD), skeletal muscle density (SMD), axial muscle density (AMD), and muscle indices.

Purpose: In the PACE-B study, a non-randomised comparison of toxicity outcomes between stereotactic body radiotherapy (SBRT) platforms revealed fewer urinary side-effects with CyberKnife (CK) compared to conventional linac (CL) SBRT. This analysis compares baseline characteristics and planning dosimetry between the CK-SBRT and CL-SBRT cohorts in PACE-B, aiming to provide insight into possible reasons for differing toxicity outcomes between the platforms.
Methods: Dosimetric parameters for the surrogate urethra (SU), contoured urethra, bladder, bladder trigone (BT), and rectum were extracted from available CT planning scans of PACE-B SBRT patients.

Aim: We aimed to evaluate whether preoperative bladder neck thickness (BNT) measured by magnetic resonance imaging (MRI) can guide surgical decisions in benign prostatic hyperplasia (BPH) and primary bladder neck obstruction (PBNO) patients with a small volume (≤30 mL).
Materials And Methods: The clinical data of 403 patients were retrospectively collected. The Kappa consistency test was used to compare subjective (IPSS-voiding) and objective (Qmax) postoperative outcomes.

Purpose: To establish a prognostic model to estimate progression-free survival (PFS) probability in bladder cancer (BCa) patients undergoing partial cystectomy.
Material And Methods: Consecutive patients who underwent partial cystectomy between August 2012 and April 2021 were enrolled. The primary endpoint was PFS during the follow-up.
