Clinical Utility of VI-RADS in Diagnosis of MIBC
Radical CystectomyMuscle-Invasive Bladder Carcinoma2 moreBladder Cancer (BCa) is the 9th most common cancer worldwide. In general, BCa is presented as a non-muscle invasive bladder cancer (NMIBC) in 70% of patients and treated with transurethral resection of bladder tumor (TUR-BT). However, in cases of muscle invasive bladder cancer (MIBC), radical cystectomy (RC) is the gold standard of treatment. Therefore, It is important to distinguish MIBC from NMIBC. To date, pathologic staging is based on the result of TUR-BT before RC. However, it is operator dependent, thus residual cancer may be remained depending on surgical experience. Therefore, about 7%-30% patients of MIBC can be underestimated with NMIBC, and it can be increased to 45% if the muscle is not resected. Consequently, it has been raised the need for imaging test to overcome diagnostic limitations. Multiparametric magnetic resonance imaging (mpMRI) has been widely used in the field of diagnosis of BCa. In 2018, the Vesical Imaging Report and Data System (VI-RADS) was published using T2-weighted imaging (T2WI), diffusion-weighted imaging (DWI), and dynamic contrast enhanced (DCE) imaging, and 5-point VI-RADS scoring system has been proposed and reported as an imaging test useful for assessing muscle involvement in primary bladder cancer Therefore, in this study, we investigate the diagnostic performance of the VI-RADS scoring system that can differentiate NMIBC from MIBC in primary bladder cancer.
Impact Advanced Recovery® for Radical Cystectomy (RC) Patients: a Pilot Study
Bladder CancerRadical Cystectomy2 moreThe purpose of this study is determine if using Impact Advanced Recovery® before and after RC surgery helps reduce surgical complications.
Randomized Trial Comparing Robotic and Open Radical Cystectomy
Bladder CancerThe purpose of this study is to determine if using robotic surgical technology during bladder cancer surgery helps to reduce complications during and after the surgery. The removal of the bladder and lymph nodes will be done by a robotic or by an open technique. It may be a Robotic-assisted Radical Cystectomy (RARC) and Pelvic Lymph Node Dissection. Or it may be an Open Radical Cystectomy (ORC) and Pelvic Lymph Node Dissection.
Comparison Study of Narrow Band Imaging Versus White Light Resection in Patients With Bladder Tumors/Cancer...
Bladder CancerThe purpose of this study is to compare the recurrence rate at 1 year following Narrow Band Imaging and trans-urethral resection of bladder tumor with White Light and TURB in patients with non-muscle invasive bladder cancer.
The Effect of Prolonged Inspiratory Time on Gas Exchange During Robot-assisted Laparoscopic Surgery...
Prostatic NeoplasmUrinary Bladder NeoplasmGas exchange disturbance frequently occurs in steep Trendelenburg position during robot-assisted laparoscopic prostatectomy or cystectomy. Due to increased intrathoracic pressure and absorbed carbon dioxide (CO2) gas insufflated into abdominal cavity, hypercapnia as well as hypoxia may occur. Inverse ratio ventilation or prolonged inspiratory time during mechanical ventilation has been reported to be improve gas exchange in adult respiratory distress syndrome. The investigators attempt to test the hypothesis that prolonged inspiratory time may improve the gas exchange during robot-assisted laparoscopic urologic surgery.
Clinical Evaluation of the miR Sentinel BCa™ Test to Diagnose Bladder Cancer in Hematuria Patients...
Bladder CancerThe purpose of the study is to establish the clinical performance and utility of the miR Sentinel™ BCa Test, a urine exosome-based diagnostic test, as an aid in diagnosing bladder cancer. Male and female participants presenting with micro- or macro-hematuria who are undergoing cystoscopy for diagnosis of bladder cancer will be eligible for the study. Urine samples will be collected at the time of the first presentation, and the miR Sentinel™ BCa Score determined and compared to the results of cystoscopy. Participants with no evidence of cancer following cystoscopy will be designated cancer-free, while those participants with a positive cystoscopy and histopathological evidence of cancer will be designated as having bladder cancer. Participants with a positive cystoscopy who subsequently undergo TURBT will be eligible to continue in the study. Urine samples will be collected at each follow up visit for up to three years, and the miR Sentinal™ BCR Score will be determined and compared to the results of surveillance cystoscopy.
PRIME: Pilot Study Evaluating Percutaneous Vaccination of BCG for Bladder Cancer
Bladder CancerApproximately 25 subjects will be enrolled and receive a standard WHO adult potency BCG immunization (1cc/50mg live mycobacilli) in the deltoid. Following a wait period after BCG vaccination, patients will then receive standard strength BCG intravesical therapy once a week for a total of 6 weeks. The BCG is instilled and held in the bladder for approximately 2 hours. While the BCG is retained in the bladder the patient should be repositioned every 30 minutes to maximize bladder surface exposure to the agent. Patients will undergo a cystoscopy every 3 months following most recent TURBT. Study duration last approximately 6 months.
Molecular Analysis Of Bladder Cancer
Bladder CancerBladder NeoplasmsThis is a laboratory study where the investigators hope to look at chromosomal events implicated in bladder cancer.
Safety Study on AdCD40L Gene Therapy for Bladder Cancer
Bladder CancerThe study objective is to evaluate the feasibility of three instillations of immunostimulating gene therapy (AdCD40L) in patients with urinary bladder cancer. Tolerance, toxicity and immunological parameters will be evaluated during and post treatment.
Quality of Life in Patients With Bladder Cancer
Bladder CancerThe purpose of this study is to learn about the quality of life of people living with bladder cancer. We are interested in learning about how the treatments for bladder cancer affect people. We plan to use the findings from this study to help doctors provide better care and information to patients with bladder cancer.
