Active clinical trials for "Urinary Bladder Neoplasms"

Radical cystectomy (RC) for bladder cancer requires reconstruction of the lower urinary tract. Both continent and incontinent diversions are available for urinary reconstruction after RC. Types of urinary diversions include ( ileal conduit, uretero-cutaneous, ureterosigmoidostomy and orthotopic bladder) The decision process is complex and involves consideration of issues related to cancer stage, patient comorbidities, treatment needs, and patient desires related to Quality of life and intraoperative findings. Outcomes of urinary diversions include 1- survival rate (cancer specific or overall survival). 2- Oncological failure (local, distant or LNs). 3- Complications (perioperative, intraoperative or post-operative). In this study, all these outcomes will be analyzed.

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

The aim of this explorative study is to evaluate whether EpiCheck can be used as a predictor of tumour response to short-term, intensive chemoresection with Mitomycin.

Bladder cancer is generally susceptible to immunotherapeutic measures. The investigators will characterize 40 patients with muscle-invasive bladder cancer regarding the existence and frequency of tumorspecific T-cells and regulatory T cells. The found data will be correlated to clinical data such as the cancer-specific survival and the response to chemotherapy. It is hypothesized that those patients with a high number of Tregs and no tumor-specific T-cells have a worse prognosis.

The goal of this study is to understand factors which may influence risk for colorectal and other cancers in families. These factors include genetic variability, in combination with diet and lifestyle. In order to achieve these goals, we need to contact as many eligible participants as possible.

To investigate the methylation status of 4-6 genes in Urine and matching bladder tissue biopsies, in order to find methylation markers for use in a noninvasive test in monitoring patients with bladder tumors.

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.

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.

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

Determine the sensitivity/resistance to chemotherapy of the various subgroups of muscle-invasive bladder cancers, including the basal subgroup (about 25% of these tumours) according to 4 different classifications based on molecular or immunohistochemical classifiers.
