Filter by:In view of sparse data of precise definition, risk factors, natural history and management of bladder perforation following Transurethral resection of bladder tumour (TURBT). We aim to correlate the relation between the site, depth and extent of resection with bladder perforation. Also, correlation between vertical depth, horizontal extent of resection and recurrence and progression of tumor
Single-bolus computed tomography urography (CTU)is a recently developed one-stop imaging examination for diagnosis of urinary tract diseases, including urinary malignancies. However, single-bolus CTU uses two post- contrast phases (i.e.: nephrographic and excretory phases) for diagnosis of urinary tract diseases. A further-developed split-bolus CTU uses solitary post-contrast phase containing mixed information of nephrographic and excretory phases for diagnosis of urinary tract disease; however, whether split-bolus CTU has similar high diagnostic values for urinary malignancies remains unaddressed. Thus, the aim of this study is to compare the diagnostic performance between single-bolus and split-bolus CTU for diagnosing urinary malignancies. This study will enroll 352 patients from two hospitals if they fit the including criteria including aged > 40 years old, presenting with gross hematuria or having urinary malignancies histories, normal renal function (i.e.: estimated glomerular filtration rate > 60 mL/min/1.73 m2, no allergic history to iodinated contrast medium and no pregnancy). All enrolled patients will be randomized to undergo split-bolus and single-bolus CTU in 1: 1 manner. Two radiologists will read CTU images independently using a standardized recording sheet with Likert scales 1-5 representing higher probabilities of presence of urinary malignancies for larger number). The diagnostic values of split-bolus and single-bolus CTU will analyzed using reference standards by final diagnoses of urinary malignancies (i.e.: presence of urinary malignancies based on histological examinations of cytology examinations, biopsies or surgical specimens). The diagnostic performance of split-bolus CTU and single- bolus CTU for urinary malignancies will be compared using areas under receiver operating curve (ROC) to determine whether there is presence of significant difference .
This research study is studying a positron emission tomography (PET) agent called 18F-fluciclovine to evaluate how well 18F-fluciclovine-PET scans determine the extent of muscle invasive bladder cancer (as compared to regular CT and MRI imaging) and whether 18F-fluciclovine-PET scans can provide information about the pathologic grade of the tumor.
The purpose of this research study is to test the safety of avelumab and AVB-S6-500 and see what effects (good and bad) this combination treatment has on patients with advanced urothelial carcinoma.
The purpose of this study is to evaluate the efficacy and safety of lenvatinib (MK-7902/E7080) in combination with pembrolizumab (MK-3475) in the treatment of cisplatin-ineligible participants with a Programmed Cell Death-Ligand 1 (PD-L1) Combined Positive Score (CPS) ≥10, or in participants ineligible for any platinum-containing chemotherapy regardless of CPS, with advanced/unresectable or metastatic urothelial carcinoma (UC). The primary hypotheses for this study are that: 1. Pembrolizumab + lenvatinib is superior to pembrolizumab + placebo with respect to Progression-free Survival (PFS) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) by blinded independent central review (BICR), and 2. Pembrolizumab + lenvatinib is superior to pembrolizumab + placebo with respect to Overall Survival (OS). With Amendment 3 (effective: September [Sep]-24-2021) participants discontinued lenvatinib and placebo; participants who remained on treatment in the study arms received open-label pembrolizumab. With Amendment 3 the external Data Monitoring Committee was discontinued. With Amendment 4 (effective: December-5-2022) Second Course will no longer be offered. Any participant receiving Second Course treatment prior to initiation of Amendment 4 will be able to complete treatment as planned. With Amendment 4 study participation will end after the final administration of pembrolizumab. Participants who either complete 35 administrations of pembrolizumab or discontinue pembrolizumab will discontinue from the study following the safety follow-up visit. AEs and spontaneously reported pregnancies will be reported and followed per protocol. All participants in efficacy follow-up prior to initiation of Amendment 4 will stop efficacy assessments and be discontinued from the study. All participants in survival follow-up prior to initiation of Amendment 4 are considered to have completed the study and should have a final survival contact. The overall study ends when the last participant completes the last study-related contact or visit, withdraws from the study, or is lost to follow-up.
This trial will include metastatic urothelial carcinoma patients who progressed during or after treatment with anti-PD(L)1 therapy and have been treated by a platinum-containing regimen, or are cisplatin-ineligible. Patients will receive either paclitaxel in combination with durvalumab (anti-PDL-1) and a single dose (300 mg) of tremelimumab (anti-CTLA4), or paclitaxel with only a high dose of tremelimumab (750 mg). Tremelimumab (750 mg), without paclitaxel will be used as a comparison arm. A run-in safety phase will be followed by a non-comparative 3-arm randomized study with a Simon's 2-stage optimal design.
This phase I/II trial studies the side effects and best dose of tazemetostat and how well it works when given together with pembrolizumab in treating patients with urothelial carcinoma that has spread to nearby tissue or lymph nodes (locally advanced ) or from where it first started (primary site) to other places in the body (metastatic). Tazemetostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving tazemetostat and pembrolizumab may work better in treating patients with urothelial carcinoma compared to pembrolizumab without tazemetostat.
This phase II trial studies how well pemetrexed and avelumab work in treating patients with MTAP-deficient urothelial cancer that has spread to other places in the body. Pemetrexed may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as avelumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving pemetrexed and avelumab may work better in treating patients with MTAP-deficient urothelial cancer.
The purpose of this study is to test the safety of a combination of the study drug called WST11 and PDT. Photodynamic therapy (PDT) is a type of ablation therapy (treatment which destroys tumor cells) which has been previously approved for the treatment of patients with other cancers. It works by using a drug that is given through the vein and then is activated in the tumor by light administered during endoscopy, which results in destruction of the cancer cells.
This study evaluates the safety and efficacy of the combination of Avelumab, (a fully human anti-programmed death ligand 1 (PD-L1) IgG1 antibody) in combination with a taxane chemotherapy (docetaxel) in patients with metastatic urothelial cancer who are either ineligible to receive cisplatin based chemotherapy, refractory to cisplatin in first line setting or have disease relapse after receiving cisplatin based chemotherapy within a year in the neoadjuvant or adjuvant setting.
