Filter by:The aim of this study was to develop an radiomic model based on CT images to evaluate markers of the bladder cancer microenvironment, such as TSR,TIL, and IP. Secondly, the association of the radiomic model with clinical outcomes and immunotherapy response was investigated.
The World Health Organization 2016 bladder tumor classification reported that the diagnosis of variant histology has increased from 6% to 33% in the last 2 decades, and there is an increasing interest in investigating the effects on disease management, treatment options, and survival outcomes in bladder tumors with variant histology. In bladder tumors, variant histology is known to be more aggressive and has a worse prognosis than pure urothelial cancer, and most cases are muscle invasive at diagnosis. Neoadjuvant cisplatin-containing combination chemotherapy is known to improves overall survival in patients with urothelial cancers. However, it is unclear whether patients with non-pure urothelial cancer (variant) histology will also benefit from neoadjuvant chemotherapy. The investigators aimed to evaluate the role of Neoadjuvant cisplatin-containing combination chemotherapy in the final treatment plan and its impact on survival in patients with bladder cancer who were diagnosed with variant histology in the radical cystectomy specimen.
VI-RADS was an observational, prospective, multicenter, no profit study. The aim of the study was to clarify the clinical validity of the Vesical Imaging-Reporting and Data System (VI-RADS) for the assessment of muscle invasion (MI) status in comparison with transurethral resection of bladder cancer (TURB) and to evaluate the diagnostic accuracy of the score according to the specific tumour location.
This is a prospective cross-sectional survey-based study composed of both a retrospective chart review and 3-series patient survey. This study will help elicit potential areas throughout the perioperative course of radical cystectomy to improve patient resilience and quality of life, providing opportunity for future interventional studies.
Bladder cancer (BC) is one of the most common type of cancer globally. Due to its high incidence rate, high risk of recurrence and progression, and frequent cystoscopy surveillance, BC contributes to major healthcare costs across the world. The goal of this prospective study was to evaluate the prognostic value of novel non-muscle invasive bladder cancer (NMIBC) biomarkers for predicting disease recurrence or progression after radical transurethral resection of bladder tumour (TURBT). The data obtained from this study may help physicians identify patients who are at greater risk of NMIBC recurrence or progression and require close supervision.
The START study is a multicentre retrospective project. The aim is to identify clinico-pathological predictors of residual tumor at time of second transurethral resection of bladder tumor (re-TURBt) and to identify well-selected candidates for a risk-adapted strategy in which this procedure could be safely spared.
Bladder cancer is the second most prevalent urological malignancy worldwide, with a high incidence and poor patient prognosis. Achieving early diagnosis and intervention for bladder cancer is one of the most important ways to improve clinical management and patient prognosis. Tumor exosomes can be released into biological fluids at an early stage of a tumor, and many studies have shown that exosomal RNA can be used as a reliable biomarker to diagnose tumors in a non-invasive way. Based on the clinical needs for early diagnosis of bladder cancer, we aim to screen several early diagnostic markers with potential predictive value, establish an early diagnostic model for bladder cancer, and validate the validity and reliability of this diagnostic model through a large-scale clinical cohort to complement the diagnosis of early-stage cancers and to improve the rate of early diagnosis of cancer.
This is a retrospective study on bladder cancer in French painters' population. The French agency ANSES collected data from all occupational and environmental diseases center in a specific database called RNV3P. We selected cases of bladder cancer in painters in four centers from 01/01/2010 to 31/12/2019. Those cases were analyzed in terms of occupational exposure, histology and sociodemographics data. Comparison between different histologic types of cancer, workplaces and occupational diseases process will be done.
Early detection of bladder cancer (BCa) is considered an effective strategy to curb mortality from the disease. However, current urinary biomarkers have insufficient specificity to warrant BCa screening. Urine free glycosaminoglycan profiles (or GAGomes) are promising noninvasive biomarkers of cancer metabolism. In this study, samples are obtained from patients with BCa and controls to compare the glycosaminoglycan profiles between groups.
The goal of this study to investigate the volatile organic compounds (VOCs) in the urine samples of both healthy individual and bladder cancer patients, using gas chromatography - mass spectrometry. Researchers aim to find a set of certain VOCs specific to bladder cancer and use this set to construct a diagnostic model that can help diagnosing bladder cancer. Participants will be asked to collect their early morning midstream urine in a predesignated container. Researchers will compare urine VOCs from bladder cancer patients and healthy individuals to see if there is any VOC whose concentration differ significantly among the two groups.
