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.

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.

This study includes two semi-consecutive parts: Part I Open label, controlled, Calibration part aimed to calibrate the CellDetect® device for identifying bladder cancer cells in urine samples. Part II Prospective, controlled, blinded part to determine the performance of the CellDetect® device in monitoring bladder cancer recurrence in patients with a history of TCC, using urine cytology samples The following subjects will be enrolled: Subjects previously diagnosed with bladder cancer undergoing routine cystoscopic surveillance, TURT or Cystectomy.

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.

This is a cross-sectional study evaluating mood disorders in bladder cancer patients and their caregivers across the bladder cancer trajectory

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.

Retrospective monocentric study evaluating different immunohistochemical phenotypes related to mitochondrial functions with treatment outcomes

Bladder cancer is the most common malignancy involving theurinary system and the ninth most common malignancy worldwide .In Egypt, the urinary bladder cancer accounted for about 31% of the total incidence of cancers that subsequently decreased to 12% in the recent years .Transitional cell (Urothelial) carcinoma is the most common type of bladder cancer, about more than 90% all bladder cancers . Other pathological types are less common such as squamous cell carcinoma (observed in about 5% of bladder cancers), adenocarcinoma (observed in approximately 1% of bladder cancers) and small cell carcinoma. Urothelial carcinomas are divided clinically into superficial tumors and muscle invasive tumors. Grossly they may appear in various forms, most commonly papillary, but may also appear as a nodule or an irregular solid growth .Accurate prediction of progression is essential need in T1 bladder cancer (BCa) because the stakes are high for this disease. About one-third of patients never recur after initial treatment, one-third have cancer that recurs as non-muscle invasive BCa (NMIBC), and one-third progress to muscle-invasive BCa with significantly worse clinical outcome . Recurrence and progression rates for pT1 tumors are highly variable Accurate prediction of progression is essential need in T1 bladder cancer management. There is difficulty in predication of T1 progression due to intrinsic difficulty in assessing the presence and extent of invasion. Patient prognosis and management have been affected by the Identification of the muscularis mucosa (MM) by Dixon and Gosling in 1983 . Elderly patients with bladder cancer frequently have comorbid conditions that make conservative management preferable for early invasive urothelial carcinomas. Several studies have explored the utility of evaluating the spatial relationship of invasive tumor to the Muscularis mucosa for sub classification of pT1 urothelial carcinomas . Muscularis mucosa consists of thin and wavy fascicles of smooth muscle frequently associated with large, thin-walled blood vessels in the submucosa of the bladder wall . It can be identified in 15-83% of biopsy specimens . T1 bladder staging has been changing and led to its classification into two groups: T1a (minimally invasive) tumors (i.e., tumors that extend into the lamina propria but are located above the level of the MM), and T1b (invasive) tumors (i.e., tumors that invade beyond the MM). Treatments for T1 bladder cancers are grouped into three categories. First, the tumour can be resected (TURBT) at the initial or restaging setting, which can be performed with white or blue-light cystoscopy. The second approach involves intravesical BCG administration with multiple years of maintenance therapy. Finally, aggressive or high risk T1 bladder cancers can be managed by radical cystectomy at 'early' or 'delayed' time points relative to diagnosis .
