Active clinical trials for "Urinary Bladder Neoplasms"

Bladder cancer is the most common malignancy of the urinary tract and accounts for about 3.2% of all cancer worldwide where it remains the seventh most commonly diagnosed malignancy in the male population. Causative risk factors can be broadly divided into inherited and acquired due to environmental exposure ,Tobacco smoking is the most important environmental risk factor for bladder cancer(1). Histologically, over 90% of bladder tumors are transitional cell carcinomas. The other subtypes, such as squamous cell and adenocarcinoma, are uncommon and account for 5 and <2%, respectively(2). Radical cystectomy with pelvic lymph node dissection with appropriate urinary diversion remains the mainstay of surgical treatment for muscle invasive bladder cancer and for high risk non muscle invasive disease. Select group of patients or those unfit or unwilling for surgery are managed by trimodal therapy utilizing transurethral resection and chemoradiotherapy.(3) The ideal urinary diversion should successfully preserve renal function while managing urinary outflow and minimizing morbidity to the patient(4).Several types of urinary diversion are present, continent and incontinent. Our study will focus on ileal conduit and cutaneous ureterostomy. Although ileal conduit considered the standard method for incontinent urinary diversion, it is associated with early bowel related complications, i.e., bowel obstruction, prolonged ileus, and anastomotic leak which are mainly associated with bowel resection and anastomosis and late complications comprise ureteroenteric stricture, urinary fistula and stomal site complications in 25-60% of patients, including stomal stenosis, retraction, prolapsed, and parastomal herniation. Cutaneous ureterostomy may represent a method of choice for elderly and otherwise morbid patients due to its relative short duration and less bowel and metabolic complications but it has a high rate of stomal stenosis making perminant stenting is mandatory(5). Cutaneous ureterostomy with separate stomas offers easy exchange of stents not need tertiary center with fluoroscopy or endescopy guidance compared to cutaneous ureterostomy with single stoma and this is preferable in our community.

Preoperative subclinical DVT screening in locally advanced bladder cancer patients candidate for radical cystectomy.

To pinpoint the clinical ,epidimiological factors and clinical outcomes in urinary bladder cancer patients attending to our department during 5 years period between 2015-2019.

To compare the perioperative, functional, and oncologic outcomes between non nerve sparing and nerve sparing robot-assisted radical cystectomy with orthotopic ileal neobladder in male patients with bladder cancer.

assess diagnostic performance of 3-Tesla DW-MRI in detecting and staging bladder cancer and potential role of the ADC value as a biomarker reflecting histological grade and stage.

Bladder cancer is the seventh cause of cancer mortality in France. Overall survival is poor, between 45 and 50% at 5 years. Optimal staging of lymph nodes and metastasis is crucial for treatment decision of muscle invasive bladder cancer (MIBC). Guidelines do not recommend FDG-Positron Emission Tomography (PET) Computed Tomography (CT), but rather CT for lymph node and metastatic staging, despite its low accuracy. We performed a retrospective analysis of patients undergoing PET CT for localized MIBC in two centers, to help define the utility of PET CT in this setting.

The study aims to study alterations of MTDH gene expression in the serum of bladder cancer patients compared to control group to evaluate its role as a marker for diagnosis. ,to compare the diagnostic accuracy of MTDH with the previously used marker Bladder Cancer-Specific Antigen-1 (BLCA-1 in the serum of bladder cancer patients . and to study correlation between expression of the metadherin gene and serum level of BLCA-1, and clinical and histopathological staging in patients with bladder cancer

Estimate the response to modified hypofractionated radiotherapy concurrent with Gemcitabine in urinary bladder cancer patients . Estimate local control, relapse free survival, overall survival and bladder preservation rate. Evaluate the toxicity of a modified hypofractionated chemoradiotherapy protocol for patients with invasive bladder cancer.

This project focuses on developing specific and sensitive detectors of biomarker-based signatures associated with diagnosed and recurrent bladder cancer.

To develop a simple blood and urine test that we would perform before patients start their treatment to predict the risk that their bladder cancer might come back. To develop this test the investigators plan to analyze blood, urine and cancer tissue from bladder cancer patients and follow them closely during and after treatment. This will include looking for changes in proteins and genes that might play a role in bladder cancer biology. The investigators will then compare the information obtained from the studies of blood, urine and cancer tissue between patients that are cured and those whose cancer comes back. The knowledge about these differences between patients can then potentially be used to develop a blood or urine test to tell us who has a high risk for having bladder cancer come back.
