Active clinical trials for "Urinary Bladder Neoplasms"

The purpose of the present study was to find out the difference in current intensity required for nerve stimulation according to the presence or absence of neuromuscular blockade during the obturator nerve block procedure for TURP.

This prospective study aims at using Artificial intelligence to create a helpful unbiased machine learning-based model that predicts BCG unresponsiveness in high risk BCG-naïve NMIBC patients incorporating all potential clinico-pathological, radiological and/or molecular prognostic factors.

The primary objective of this study is to assess the safety and effectiveness of Human Multigene Methylation Detection Kit (Fluorescent PCR Method) for help diagnose bladder cancer by comparing with clinical standard method (includes medical imaging (MRI, CT, etc.), cystoscopy, pathological examination).

Endoscopic retrograde cholangio pancreatography procedure will performed as per local standard procedure.After common bile duct cannulation,cholangiography will be performed (to confirm the stricture) followed by biliary sphincterotomy. All biliary strictures(Bismuth Type I/II/III/IV) will be enrolled for the study. Patient opting for Uncovered self expandable metallic stent / Plastic stent will undergo biliary stent placement and considered under control arm Patient opting for radio frequency ablation + Uncovered SEMS/Plastic stent will undergo radio frequency ablation and biliary stent placement and considered under Study arm The RFA probe will be inserted into the bile duct alongwith the guidewire. Keeping the electrode overlapping the stricture, RFA will be performed using a power of 10W for 120 seconds. The electrode will be kept at the ablation site for an additional 1 minute to allow the RFA probe to cool before removal to prevent thermal injury of normal tissue and/or endoscope accessory channel. If the stricture is more than 3 cm, step-by-step RFA will be performed from the superior to inferior aspect. After RFA application, an uncovered SEMS/Plastic stent will be placed.

The primary objectives of this study are (1) to compare the incidence of breast cancer, by insulin use at cohort entry, among females with type 2 diabetes who are new users of dapagliflozin and females who are new users of antidiabetic drugs (ADs) in classes other than sodium-glucose cotransporter 2 (SGLT2) inhibitors, insulin monotherapy, metformin monotherapy, or sulfonylurea monotherapy and (2) to compare the incidence of bladder cancer, by insulin use at cohort entry and pioglitazone use, among male and female patients with type 2 diabetes who are new users of dapagliflozin and those who are new users of ADs in classes other than SGLT2 inhibitors, insulin monotherapy, metformin monotherapy, or sulfonylurea monotherapy. Secondary objectives will compare, by insulin use at cohort entry, frequency of several measures of health care use, baseline characteristics, and incidence of selected other cancers in males and females between the two exposure cohorts.

Background: Bladder cancer is the sixth most common cancer in the United States. The way that doctors remove tumors in bladder surgeries may leave some cancer . Also, many people have their tumors return or progress after surgery. Researchers want to test a modified device. It might tell doctors more about bladder tumors. Objective: To see if using a modified standard device with bladder surgery can provide better information about tumors in bladder specimens. Eligibility: People ages 18 and older who need to have their bladder removed at the NIH. Design: Participants will be screened with: Medical and prior surgical history Review of existing MRI, x-ray, or CT scans Review of existing specimens and reports Pregnancy test for women of childbearing age CT or MRI: Participants will lie in a machine. The machine will take pictures of their body. Participants will have bladder surgery. This will occur in the same way as if they did not take part in this study. A member of the research team will cut the removed bladder using the modified device. This will most likely be done on a separate back table in the operating room. The bladder and samples after cutting will be sent out for review. The will occur just as it would if the participants were not in this study. The only difference is the way that the specimen is prepared for review. Participants follow-up care will occur per standard of care. Or it will occur as part of any other study in which they might also be enrolled.

Although transurethral resection is the main treatment option for stage Ta and T1 disease, relapse is frequently detected. Tumor number, tumor size, T stage, presence of in situ carcinoma and tumor grade are risk factors for recurrence. The relationship between post voiding residual urine volume and bladder tumor recurrence and progression has not been clearly established. The investigators aimed to examine the effect of high post voiding residual urine volume on recurrence and progression based on the hypothesis that tumor cells circulating in the bladder may increase with excess residual urine.

In this phase II study, eligible patients will be treated with maximal tumor resection and then started treatment within 8 weeks. Chemotherapy, Nivolumab and radiotherapy (RT) will be started on day one. Chemotherapy will be administered weekly during radiotherapy. Radiotherapy will be performed from Monday to Friday for five weeks. Nivolumab will be administered for one year (13 infusions). Patients will have the complete tumour assessment by computed tomography scan (CT-scan) and cystoscopy up to 5 years after radiotherapy.

The aim of this study is to evaluate the effect of Verity-BCG in patients with intermediate and high-risk non-muscle-invasive bladder cancer (NMIBC) and to compare our findings to the standard of care BCG formulation, OncoTICE (BCG) in order to examine our hypothesis that Verity-BCG is at least non-inferior to OncoTICE in achieving 24-month Recurrence Free Survival in NMIBC patients who are at high risk of recurrence and have never been treated with intradermal or intravesical BCG before, with the exception of tuberculosis vaccination in childhood.

Around 7200 cases of Muscle Invasive Bladder Cancer are diagnosed annually in the Nordic countries combined. Muscle Invasive Bladder Cancer is an aggressive disease and it is linked with high mortality rates. The golden standard of treatment is radical cystectomy (RC) (the surgical removal of the bladder) and radical removal of lymph nodes in the pelvis. In addition to surgical treatment, and especially in cases where the tumour invades tissues surrounding the bladder or lymph nodes, chemotherapy is recommended. Chemotherapy can be administered before or after surgery, in a neoadjuvant (NAC) or adjuvant setting (AC). Although most patients recover well from surgery, there are significant risks regarding radical cystectomy. The greatest challenges in planning the treatment are making individual risk assessments and prognosis for the treated patients. Neoadjuvant chemotherapy is also insufficiently used and it is hard to predict how the tumour responds to chemotherapy. The purpose of this study is to collect prospective clinical data on radical cystectomy -patients in co-operation with other Nordic countries: Sweden, Denmark, Iceland and Norway. The collected data is used to validate existing prediction tools and discover novel tools for prediction of morbidity related to RC and prediction of oncological outcome after RC. The study is divided into three sub-studies. The first sub-study is to validate low albumin levels as a predictor of complications after RC . The cut-off for low albumin has been <3,5 mg/l across the studies. This could be a very cost-effective biomarker but currently its relevance is limited by lack of proper prospective validation studies. The primary end-point in the Albumin sub-study is the 90-day major (Clavien Dindo 3-5) complication rate. The secondary end-points include total 90-day complication (Clavien 1-5) and 90-mortality rate (Clavien 5) for all patients and complication rate during NAC for patients receiving chemotherapy.
