Active clinical trials for "Urinary Bladder Neoplasms"

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 .

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

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

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.

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.

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

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.
