Active clinical trials for "Urinary Bladder Neoplasms"

Our multicenter observational study is a non-profit prospective study. The study was born from the Amplitude Project, which comprise the SOD of Minimally Invasive Robotic Urological Surgery and Renal Transplants of AOU Careggi with the University of Florence, as well as with the National Research Council (CNR) and the University of Milan Bicocca (UNIMIB) The study consists of a phase of enrollment of patients who will be admitted to the SOD of Mini Invasive Robotic Urological Surgery and Renal Transplantation of AOU Careggi. Enrollment in the study does not alter normal clinical practice and does not involve additional risks for patients. Patients will have to meet the inclusion and exclusion criteria of the study and will be enrolled sequentially, until the established sample size is reached. Patients undergoing surgery for the removal of bladder neoplasm, be it endoscopic or surgical with radical intent (cystectomy), will be taken a fragment of tumor bladder tissue, on which histopathological analysis will be performed. In patients undergoing radical cystectomy only, a fragment of healthy urothelial tissue, free from neoplasia, will also be removed. The samples will be performed in patients under general and / or spinal anesthesia in case of TURB, thus not causing pain or discomfort to the patient, or ex-vivo on the operative piece in case of radical cystectomy, without causing further damage or pain to the patient. From these samples, specially stored in solutions that keep their characteristics unaltered, a 3D culture model (organoid) will be obtained both from cells obtained from bladder cancer and from healthy tissue on which biomolecular, metabolomic and spectroscopic characterization studies will be tested and carried out. with a view to staging and grading bladder neoplasia.

The study aims to collect data on ERBT globally in order to clarify its role in the management of bladder cancer over a 5-year observation period.

Conventional monopolar or bipolar transurethral resection of bladder tumors is the most common method for resection of a bladder mass. En bloc resection has demonstrated success in the literature utilizing different techniques and lasers, including utilizing the Ho:YAG and Tm:YAG lasers. A recent metanalysis revealed several benefits to laser en bloc resection including less complications and lower recurrence rate.22 Subsequently, laser technology has also advanced with the development of a super pulsed TFL which overcomes many limitations of prior traditional lasers. Olympus' SOLTIVE™ TFL, which has demonstrated improved maneuverability and control, has a shallow depth of tissue penetration at 0.15mm leading to precise resection and optimal hemostasis. Despite these beneficial characteristics and qualities along with the promising utility of en bloc resection, the Olympus SOLTIVE™ TFL has not been described in en bloc resection of bladder tumors. The investigator seek to determine if the proposed benefits of this device can be realized both pathologically and clinically in en bloc resection of bladder tumors.

The purpose of this study is to assess the performance of multiparametric MRI in detection of occult muscle invasion in urinary bladder cancer

The objective of this prospective, multi-centre study is to evaluate the performance of ADXBLADDER, a urine MCM5 ELISA test, as an aid in the detection of bladder cancer recurrence. Patients undergoing cystoscopic surveillance in non-muscle invasive bladder cancer (NMIBC) follow-up will be recruited and asked to provide a urine sample to be tested with ADXBLADDER. To assess the diagnostic accuracy of the test, the MCM5 results will be compared with the gold standard cystoscopy and pathology of resected tissue.

This study prospectively included 178 patients with bladder neoplastic lesions who planned to undergo surgery (with or without preoperative neoadjuvant chemotherapy). Inclusion criteria: Patients with pathologically confirmed bladder cancer after radical or partial cystectomy or TURBT (< 2 weeks between surgical resection and imaging). Exclusion criteria: 1) Prior history of chemotherapy and/or radiotherapy; 2) No surgical resection; 3) The interval between surgical resection and imaging examination is > 2 weeks; 4) Obvious artifacts; 5)MRI scan contraindications. All subjects underwent pelvic MRI. Data was collected using a Siemens VIDA 3TMR scanner (Siemens Healthcare, Erlangen, Germany). All subjects underwent standardized scanning protocols. The obtained images are post-processed and the experimental results are analyzed statistically.

A prospective, investigational study to assess the accuracy of standardized cystoscopic evaluation with tissue sampling performed immediately prior to definitive radical cystectomy to predict pathologic tumor stage and identify patients who may benefit from bladder preservation therapy.

To improve upon the non-invasive detection of BCa by further validating a multiplex ELISA assay directed at a BCa-associated diagnostic signature in voided urine samples of patients with microscopic hematuria.

This study is being done to create a registry to help us learn more about urinary and other cancers. This will let us look at large groups of people who do and do not have this kind of cancer. The investigators will look at risk factors to learn more about how these impact cancer. The investigators will also look at genetic markers. These are genes that are found in a known place. They are often associated with a particular trait. If the gene changes in some way, it may predict cancer or response to treatment. The investigators will look for markers in your saliva. This registry will help us develop better methods of: Preventing these cancers. Diagnosing these cancers. Treating these cancers.

The purpose of this study is to determine if analysis of DNA and protein material found in urine will be useful in the detection of urothelial cancer of the bladder and kidney. This analysis may be helpful to determine if how a particular cancer will act regarding remission and recurrence
