Active clinical trials for "Urinary Bladder Neoplasms"

In the investigators's previous work, measurements of intra-prostatic concentrations of sex steroids were determined on samples taken from the operating room using a punch. In order to study the in-vivo intra-prostatic concentrations of sex steroid, it is necessary to validate a measurement technique performed on samples obtained by a biopsy needle used in standard care for prostate biopsy punctures allowing the diagnosis and follow-up of prostate cancer. The aim of this project is to validate this measurement technique carried out on samples obtained by the biopsy needle and to define the optimal number of carrots obtained by biopsy offering dosage results comparable to the punch.

Is BladderLight® (BL) urine testing accurate, as a non-invasive method, to exclude presence of bladder cancer in patients.

Non-muscle invasive bladder cancer of High Grade stage T1 (HGT1), has up to 20% risk of progression to invasive disease. Because the depth of substaging seems to identify two separate groups with different progression risk (HighGradeT1a and HighGradeT1b), we design a differential treatment strategy for each group. The main hypothesis is that HighGradeT1a bladder cancer can spare a second endoscopic procedure.

This study aims to analyze the incidence of expression of MAGE-A3, MAGE-C2, NY-ESO-1, LAGE-1, WT1 and PRAME tumor antigens in cancer tissue from patients with pathologically demonstrated bladder cancer.

The purpose of the study is the identification of chromosomal aberrations in urine samples. The imaging system is intended for diagnostic use as an aid to the pathologist in the detection, counting and classification of UroVysion FISH stained Urine samples.

We propose to conduct a pilot study among 30 volunteers from the Division of Cancer Epidemiology and Genetics (DCEG) in order to: (1) select the urine pH strip that most closely correlates with urine pH measured by pH meter for the New England Bladder Cancer Study, (2) calibrate the urine pH strip that was used for the Spanish Bladder Cancer Study against pH measured by a pH meter, and (3) compare the DNA yields from buccal cells obtained from two different methods: mouthwash vs toothbrush-rinse method. Information collected from this pilot study will be used to select and optimize the sample collection protocols in the New England Bladder Cancer Study. At the time of enrollment, study participants will be asked to provide information on age, gender, height, weight, consumption of antacids and calcium supplements, and whether they ate, drank or brushed their teeth in the last hour previous to the buccal cells ample collection. In addition, they will have to measure their urine pH with four different pH strips twice a day (early morning and before dinner) for a week and record the measurements in a diary. During the same week, they will be asked to collect two spot urine samples each day from Monday to Thursday (early morning and before dinner), and one more on Friday morning, and bring them into work in a cooler. Also, they will be asked to collect a continuous 24-hour urine sample during one of the three first days of the week. Urine samples will e picked up by lab personnel from BioReliance, and pH will be measured at their laboratory with the four pH strips again and with a pH meter. Buccal cells sample collection will be completed during the first and the last day of the urine sample collection period. The first day, study participants will be asked to provide a water rinse sample after brushing the inside of their cheeks with a toothbrush, and a week later they will be asked to provide a mouth wash sample consisting of two consecutive rinses with Scope mouthwash. All samples and questionnaire data will be unlinked from personal identifiers after the sample collection is completed. Participants will be compensated with $100 for the inconvenience of participating in this complex study and for their time.

Differentiation between non-muscle-invasive bladder cancer (NMIBC) and muscle-invasive bladder cancer (MIBC) is a cornerstone in the treatment plans.Therefore, this study will try to evaluate the sensitivity and reliability of mpMRI in accurate diagnosis of cancer bladder. Primary objective: to detect the sensitivity of multiparametric MRI in differentiation between muscle Invasive and non-muscle invasive Urinary Bladder Cancer in relation to the conventional cystoscopy and histopathological examination of the biopsy.

The proposed study, IFACT - Incidental Findings in Advanced Cancer Therapy, will address this research gap by examining MSK patients' attitudes, preferences, and information needs regarding incidental findings arising from tumor genomic profiling.

The goal of this study is to develop, optimize, and validate a High Resolution Imaging System in the bladder that displays images in real-time, providing automated diagnostic criteria for bladder cancer screening. High resolution images of normal bladder tissue and suspicious bladder lesions will be collected from patients who present to the study site for clinical evaluation.

The investigators proposes a prospective cohort study in patients with high risk bladder cancer who have opted for radical cystectomy. The investigators aim to correlate pre-operative measures of body composition, cognitive and functional status with impaired survival at 6 months after cystectomy. Impairment in this context will be a compilation of several specific objective measures including: 1) death from any cause, 2) major complication (Clavien score7 ≥ 3), 3) loss of independent living status, 4) performance status, and 5) global well-being. The study team believes that Impairment Free Survival is an important endpoint as it accounts for many aspects of a patient's functional status that might alter a patient's choice to proceed with radical surgery.
