Ellipticine, an alkaloid isolated from Apocyanaceae plants, has been demonstrated to exhibit antitumor activity in several cancers. However, the effect and the mechanisms underlying its action have not been investigated in human bladder cancer cells. The aim of the present study was to investigate the effect and mechanism of ellipticine on the behavior of T‑24 bladder cancer cells. T‑24 cells were treated with varying concentrations and durations of ellipticine. Cell viability was evaluated by Cell Counting Kit‑8 assay. Cell motility was analyzed by Transwell migration assay. Flow cytometry, reverse transcription‑quantitative polymerase chain reaction and western blot analyses were performed to detect the cell cycle and signaling pathways involved. The results demonstrated that ellipticine suppressed proliferation and inhibited the migration ability of T‑24 bladder cancer cells in a dose‑ and time‑dependent manner, and resulted in G2/M cell cycle arrest. The mechanism of this action was demonstrated to be due to ellipticine‑triggered activation of the ATM serine/threonine kinase pathway. These data therefore suggest that ellipticine may be effective towards treating human bladder cancer.

Introduction: Thick-walled gallbladder (TWGB) is a common yet non-specific radiological finding associated with a wide range of gallbladder pathologies, including acute and chronic inflammation, infection, and malignancy. Among the inflammatory causes, xanthogranulomatous cholecystitis (XGC) is a rare but significant condition that often mimics gallbladder carcinoma. This paper presents a pragmatic approach to the diagnosis and management of TWGB, focusing on the complexities posed by XGC.

Background And Purpose: A novel ring-gantry cone-beam computed tomography (CBCT) imaging system shows improved image quality compared to its conventional version, but its effect on autosegmentation is unknown. This study evaluates the impact of this high-performance CBCT on autosegmentation performance, inter-observer variability, contour correction times and delineation confidence, compared to the conventional CBCT.
Materials And Methods: Twenty prostate cancer patients were enrolled in this prospective clinical study.

Brachytherapy is a key treatment for gynaecological malignancies, delivering high doses to the tumour volume whilst sparing nearby normal tissues due to its steep dose gradient. Accuracy is imperative as small shifts can lead to clinically significant under- or over-dosing of the target volume or organs at risk (OARs), respectively. Independent verification of dose delivered during brachytherapy is not routinely performed but it is important to identify gross errors and define action thresholds to guide inter-fraction treatment decisions.

Objective: To investigate the expression patterns of Nectin-4, the target molecule of the antibody-drug conjugate enfortumab vedotin (EV), in relation to histological and molecular subtypes of urothelial bladder cancer (UBC).
Patients And Methods: We assessed the protein expression patterns of Nectin-4 in a spatially organised tissue microarray containing 1386 tissue cores from 314 consecutive patients with UBC who underwent radical cystectomy (2005-2018). Results were correlated with clinicopathological and follow-up data, as well as with different spatial locations (tumour central vs tumour-normal interface and primary tumour vs lymph node [LN] metastases).

Background: The role of repeat transurethral resection of bladder tumor (TURBT) for the management of nonmuscle invasive bladder carcinoma is debated, especially when initial resections include detrusor muscle. This study compares immediate second resection (additional deep biopsies in the same session) with standard restage TURBT performed 2-6 weeks post-initial TURBT to determine adequacy in detrusor muscle sampling and compare the disease rate at restage TURBT in both groups.
Material And Methods: A randomized trial was conducted at a tertiary care hospital, including patients aged ≥18 years undergoing TURBT with complete primary tumor resection.
