Active clinical trials for "Urinary Bladder Neoplasms"

To investigate the use of antibiotic prophylaxis in patients undergoing TURP and TURB. The investigators set up a prospective, randomized controlled trial in which (after exclusion of risk factors) patients will be randomized in receiving levofloxacin (Tavanic) orally or no antibiotics. The exclusion criteria for TURP are a pre-operative transurethral catheter or > 100 urinary white blood cells in the pre-operative urine sample. The exclusion criteria for TURB are a pre-op catheter or clinical signs of infection.

This is an open label, multicenter, phase 1/1b study to assess safety/tolerability and preliminary clinical activity of E7766 as a single agent administered intravesically in participants with NMIBC. Both intermediate risk and BCG-unresponsive NMIBC participants will be included.

Purpose To investigate the significance of time to re-staging transurethral resection (re-TUR) on recurrence and progression rates in patient with high-risk non-muscle-invasive bladder cancer. Methods Patients diagnosed with primary high risk non-muscle-invasive bladder cancer were included to the study. The patients were randomly seperated into 3 groups acoording to Re-TUR timing. In group 1,2, and 3, the time interval between initial and re-TUR were 14-28 days, 29-42 days, and 43-56 days respectively. Kaplan -meier plots were used to estimate differences in recurrence free survival (RFS) and progression free survival (PFS) rates. Cox regression analysis was used to assess the effect of time from initial TUR to re-TUR on oncological outcomes. Results A total of 109 patients with high risk non-muscle-invasive bladder cancer were randomly divided into 3 groups. Twenty patients in group 1 (14-28 days), 22 patients in group 2 (29-42 days), and 29 patients in group 3 (43-56 days) completed the study. The mean follow-up was 20 ± 8.9 months. Kaplan-Meier plots showed no differences in RFS and PFS rates between the three groups. Cox regression analysis demonstrated that only tumor number was found to be a prognostic factor on RFS rates. Conclusion Our prospective study demonstrated that time laps from initial TUR to re-TUR did not significantly affect on RFS and PFS rates.

This is a multi-site, randomized, prospective, open-label phase II study. Patients in this study will have localized (cT3-cT4), or metastatic bladder cancer with a symptomatic, intact primary bladder tumor. In this study, patients will undergo stereotactic body radiation therapy (SBRT) to the bladder tumor and will receive durvalumab with or without tremelimumab.

A cystectomy is the removal of the bladder and adjacent organs in patients with bladder cancer. This often results in significant blood loss, and about 60% of patients will require a blood transfusion during or up to 30 days after surgery. Significant blood loss may result in cardiovascular morbidity, and the use of blood products are expensive and expose patients to risk. Tranexamic acid reduces breakdown of hemostatic blood clots and it has therapeutic benefit when used in other surgical procedures to reduce blood loss and the need for transfusion. The current study will be the first to evaluate whether tranexamic acid is effective and safe to use during radical cystectomy. The results of the study will have an immediate impact on patient care.

The purpose of this study is to learn if bladder cancer patients can follow a diet and exercise program during treatment and whether the program will improve results of their treatment.

A multi-institutional, prospective, randomised, open-label, superiority, comparative, active-controlled, phase 3 study. The study will compare Synergo RF-induced hyperthermia-chemotherapy (SHTC) plus mitomycin C (MMC) to standard treatment of bacillus Calmette-Guérin (BCG) therapy as first-line adjuvant treatment for intermediate and high-risk NMIBC, and will evaluate recurrence and progression rate over two years of follow-up.

The purpose of this study is to compare the safety and efficacy of EN3348 (MCC) versus BCG as first line treatment in patients with non-muscle invasive bladder cancer that are at high risk for recurrence or progression.

Early single instillation of chemotherapy after TUR is recommended in the European Association of Urology Guidelines. Nevertheless, the procedure is suboptimal for patients with multiple tumors, sometimes is not tolerated and it can results in severe complications. In both laboratory and clinical studies, intravesical electromotive drug administration (EMDA) increases mitomycin-C (MMC) bladder uptake, resulting in an improved clinical efficacy in non-muscle invasive bladder cancer (NMIBC). The investigators will compare the effects of one immediate pre-TUR intravesical EMDA/MMC instillation with one immediate post-TUR intravesical passive diffusion MMC (PD/MMC) instillation and TUR alone in patients with NMIBC. All eligible patients with primary NMIBC will be randomized into 3 groups who will undergo transurethral resection alone (TUR/alone); TUR plus single immediate postoperative instillation (immediately after TUR) of 40 mg PD/MMC with a dwell time of 60 minutes; or single immediate preoperative instillation (immediately before TUR) of 40 mg EMDA/MMC with 20 mA electric current for 30 minutes. Patients with intermediate and high risk NMIBC will undergo adjuvant intravesical therapy. The primary end points will be the recurrence rate and disease-free interval. All clinical analyses will be performed on an intent to treat basis.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving the drugs in different ways may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of gemcitabine given directly into the bladder in treating patients who have recurrent or refractory bladder cancer.
