Active clinical trials for "Urinary Bladder Neoplasms"

ProCSUCaB (Prospective Collection of Samples for Urothelial Cancer of Bladder) is a monocentric, non-interventional, prospective registry that will recruit newly diagnosed intermediate- and high-risk NMIBC patients in a tertiary center in Flanders.

The purpose of this pilot study is to determine if washing out the bladder with large volumes of saline after surgical removal of bladder tumors helps to decrease the number of loose cells floating within the bladder after surgery. Anticipated decrease in tumor recurrence and/or progression rates will be measured.

Urinary bladder cancer is a common malignant tumor of the urinary tract in both men and women. Proper management of the urinary bladder cancer depends on the stage of the lesions. Differentiating the histopathological types, tumor grade and the depth of tumor invasion are very important for determining the therapeutic approach and are highly correlated with the recurrence, progression and patient's survival. Radical cystectomy (RC) and lymphadenectomy after neoadjuvant chemotherapy is the standard treatment for muscle invasive tumors, whereas the treatment of choice for non-muscle invasive tumors is transurethral resection (TUR) ±chemo/immunotherapy. Cystoscopy with biopsy is still the best tool for bladder cancer staging due to its high sensitivity in detecting lesions and the possibilities of tumor resections, but the main drawbacks are invasiveness, limitation in detection of flat lesions, and lack of the assessment of extra-vesical tumor invasion. Modern diagnostic modalities circumvent these limitations like blue-light cystoscopic examination and infrared cystoscopy. For the radiological evaluation of the urinary bladder, magnetic resonance imaging (MRI) is a valuable imaging modality due to high tissue contrast and multiplanar imaging capabilities. Diffusion-weighted images provides useful information for evaluation of local T stage of the urinary bladder cancer, specially in differentiating T1 stage or lower tumors from T2 stage and higher tumor stages. Apparent diffusion coefficient (ADC) delineating the degree of water molecular diffusion and the degree of restriction to water diffusion in biological tissues is inversely correlated to the integrity of the cell membranes and the tissue cellularity. The apparent diffusion coefficient (ADC) value has been revealed as quantitative measure of the degree of malignancy of the lesions. Decreased ADC values were reported with malignant lesions which have a larger cell diameter and more cellularity than normal tissue.

The purpose of this study is to evaluate the effect of fresh gas flow on emergence time in patients undergoing transurethral resection of bladder tumor.

To provide patients with bladder cancer who are scheduled to undergo radical cystectomy with a preoperative high-arginine nutritional supplement. The investigator will measure patient adherence to the regimen, tolerability of the supplement and feasibility of supplementation. Secondary outcome measures will include differences in length of stay and complication rate between groups.

The folate receptor is over-expressed on many types of cancer cells and new folate receptor targeted therapies are being developed to target cancer cells that over-express the folate receptor. As with other targeted therapies, it is important to develop diagnostic tests that will provide accurate information on folate receptor status and aid in selecting patients that may benefit from folate-targeted therapy.

The purpose of this study is to evaluate whether a new potential treatment for non invasive bladder cancer is safe and if it leads to side effects such as irregular heart rate, agitation, or burning with urination. Patients who have early stage bladder cancer and will be receiving BCG, a bladder cancer therapy as recommended by a doctor, will be asked to participate in a study where they are given the standard BCG followed by the experimental drug, aminophylline. Although we hope this medicine may one day prove to help bladder cancer patients, at the current time we do not know if it has any benefits at all. We have data in mice that suggest that aminophylline slows the growth of tumors when coupled with BCG.

Bladder cancer is the second most prevalent urological cancer in France. About 1 in 5 new cases of bladder cancer infiltrate the muscles. The standard treatment is neoadjuvant chemotherapy followed by radical cystectomy associated with reconstruction of the urinary tract. The short-term effects on well-being and quality of life are well known. The long-term effects are, on the other hand, poorly understood, particularly sexual function. This study aim to asses the quality of sexual life in patients with cystectomy for bladder cancer. This will be done via various questionnaires given before and after surgery.

This phase II trial studies the safety and feasibility of utilizing acupuncture in patients with high-risk bladder cancer that has not spread to the surrounding muscle (non-muscle invasive) undergoing treatment with Intravesical BCG. BCG is a weakened form of the bacterium Mycobacterium bovis that does not cause disease. It is used in a solution to stimulate the immune system in the treatment of bladder cancer. Unfortunately, many patients experience side effects such as pelvic pain, painful urination, severe urgency, frequency, urge incontinence, need to urinate at night, and/or infectious complications. These side effects may cause patients to delay or stop BCG treatment. Acupuncture is a medical intervention in which fine metallic needles are inserted into anatomical locations of the body to stimulate the peripheral and the central nervous system. Giving acupuncture before each intravesical BCG treatment may help to reduce the side effects of intravesical BCG, and help patients complete treatment. Specific outcomes of interest include acceptability to patients, effect of acupuncture on intravesical BCG-related side effects, and adverse events associated with acupuncture.

Electronic reporting of patient-reported outcomes with alert algorithm will be tested in a randomized trial in bladder cancer patients undergoing chemo- or immunotherapy. The clinical endpoints will be: Quality of life Completion of treatment Hospital admission Dose reductions Survival
