Active clinical trials for "Urinary Bladder Neoplasms"

This randomized phase II trial studies the side effects and how well postoperative intensity modulated radiotherapy works after surgery in treating patients with urothelial bladder cancer. Radiation therapy uses high energy x-rays to kill tumor cells left behind in the pelvis after surgery. It is not yet known whether surgery followed by radiotherapy is more effective than surgery alone in treating patients with urothelial bladder cancer.

This study evaluates the continuation (non-discontinuation) of Aspirin during TURBT. Half of participants will continue their usual low-dose Aspirin regimen during TURBT and throughout the perioperative period, while the other half will discontinue Aspirin use ten days prior to surgery (standard recommendation) and restart therapy two weeks post-discharge.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combination chemotherapy combined with transurethral resection may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of transurethral resection plus combination chemotherapy in treating patients who have stage II or stage III bladder cancer.

This phase I trial studies the side effects and best dose of vaccine therapy given directly into the bladder in treating patients who are undergoing surgery to remove all or part of the bladder. Vaccines made from a gene-modified virus may help the body build an effective immune response to kill tumor cells. Giving a vaccine directly into the bladder before surgery may cause a stronger immune response and keep tumor cells from coming back after surgery.

RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. It is not yet known whether ciprofloxacin is more effective than cephalexin in preventing cancer recurrence in patients who are undergoing surgery to treat bladder cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of ciprofloxacin with that of cephalexin in preventing recurrence of cancer in patients who are undergoing surgery for bladder cancer.

The primary objective of the study is to assess the bladder cancer recurrence free rate, according to a phase II pilot study, of intravesical instillation of sequential BCG and EMDA/MMC after TUR. The study is designed as a one-sample investigation: the outcome measure is disease recurrence rate. Follow up will continue up to 5 years. For sample size determination, disease recurrence rate will be compared with literature data of recurrence rate obtained in standard BCG alone administration (Lamm's protocol).

The goal of this clinical research study is to evaluate how well ferumoxtran-10, a new Magnetic Resonance Imaging (MRI) contrast agent, can detect cancer in the pelvic lymph nodes or malignant pelvic lymph nodes.

Currently the standard treatment of muscle invasive bladder cancer is the complete removal of bladder and adjacent organs, such as prostate or ovaries. Radical cystectomy is fraught with complications and risk of death. The researchers hope to learn if chemoradiation (i.e. using chemotherapy and radiation), also an acceptable treatment for muscle invasive bladder cancer, can be used a good alternative therapy option.

miRNAs have been detected in different bodily fluids, which suggests significant potential, such as their use as biomarkers in diagnostics and prognostics. Sha-mir-71a was abundantly found in the urine of patients with bladder cancer as compared to benign bladder cystitis associated with schistosomiasis . Additionally, this miRNA was more highly detected in urine samples from patients with bilharzial bladder cancer than bladder cancer not associated with bilharziasis (schistosomiasis), suggesting its specificity in the identification of bladder cancer associated with infection.

The study will be offered to all consecutive patients undergoing scheduled cystoscopy at the Hospitalisation De Jour (HDJ) Chirurgicale, either as part of a diagnostic approach in the event of suspected bladder tumor (exploration of macroscopic hematuria in particular), or as part of the follow-up of a bladder tumor, according to current recommendations (French ccAFU guidelines - update 2020-2022: bladder cancer). Once non-opposition has been obtained, clinical data at the time of inclusion will be collected and pseudonymized. Urine is collected prior to cystoscopy, on voided urine, for a minimum sufficient quantity of 50 ml. The urine sample is then separated into transport jars, one of which is used for standard cytological analysis, the other for VISIOCYT cytology (sent to a laboratory platform). In the event of a tumor or suspicious lesion detected at the cystoscopy, a trans-urethral bladder resection (TURB) will be scheduled. Anatomopathological data from this RTUV will also be collected for comparative analysis to establish the diagnostic performance of the test. The tests performed (apart from the urine sample) are part of the usual care pathway. No additional visits will be specifically requested by the protocol. Data from examinations carried out as part of standard pathology management, or suspected pathology, will be used for this research. At the same time, prospective questionnaires on patients' preferences with regard to the various diagnostic examinations for bladder tumours (discrete choice analysis) will be given to patients and completed at the time of cystoscopy.
