Active clinical trials for "Urinary Bladder Neoplasms"

Gastric cancer and colorectal cancer are common gastrointestinal malignancies in the world.Early cancer generally has no obvious symptoms. Endoscopy is the "gold standard"for the diagnosis of gastric cancer and colorectal cancer.gastric cancer and colorectal cancer treatment mainly includes surgery and medication.Compared with traditional diagnosis and treatment methods, the application of gene detection technology, especially high-throughput sequencing technology (NGS) in tumor diagnosis and treatment, performs multi-dimensional and multi-target detection of cancer-related genes, which can quickly and accurately determine the target gene mutations Morphology and expression differences, so as to provide personalized guidance to patients in terms of medication, treatment or prognosis evaluation, which can save a lot of time and treatment costs, and improve the overall treatment effect and patient quality of life. Cystoscopy and biopsy sampling pathological testing are the gold standard for bladder cancer diagnosis, and have been widely used in clinical diagnosis and prognosis judgment. However, cystoscopy is cumbersome, expensive, and often causes pain to the patients under test. At present, the main clinical non-invasive detection technique for bladder cancer is still the cytological examination of urinary tract bladder cells in urine, and its sensitivity and specificity are not good, especially for the diagnosis of early lower grade bladder cancer.For bladder cancer, tumor tissue (puncture biopsy or surgical resection) DNA, urine ctDNA, urinary tract exfoliated cell DNA and peripheral blood ctDNA can be used for genetic testing, but the consistency of the genetic testing results of these four types of samples has not been verified, especially There is no systematic evaluation of the guidance effect of non-invasive gene detection of free tumor DNA and urinary tract shed cell DNA in the diagnosis and treatment of bladder cancer.The corresponding relationship between the significant mutation genes contained in the DNA derived from bladder urinary tract cancer and the various types and stages of bladder cancer is not clear.

The principal objective of this study consists in the assessment of Immunogenic Cell Death (ICD) induction in neoplastic tissues derived from bladder cancer patients treated ex vivo with Mitomycin C (MMC). The evaluation is performed using cellular and molecular analyses of treated versus untreated samples derived from the same patient

A prospective observational study to re-establish a new prognostic model for predicting the outcome in patients with non-muscle invasive bladder cancer (NMIBC) using the current recommendation regimen for intermediate and high risk groups and including all potential and highly prognostic factors.

Muscle-invasive bladder cancer affects over 3,000 new patients in the UK each year and radiotherapy comprises a key part of the treatment pathway for many of them. Bladder radiotherapy in the UK involves delivery of radiation to the entire bladder volume and aims to deliver a high dose to the bladder while sparing nearby healthy organs (e.g. the bowel). Unfortunately, large variations in bladder shape and volume are observed throughout treatment that compromise the probability of a positive outcome for the patient, either by increasing the risk of side-effects or by reducing the likelihood of adequately treating the disease. In recent years, the implementation of 'adaptive' bladder radiotherapy strategies has increased. These techniques allow modification of the treatment based on the observed variations in bladder shape and volume. However, these strategies often rely on daily X-ray imaging of the patient prior to treatment, which is time-consuming and associated with a small risk of inducing a cancer in the patient. This study will evaluate the potential of a commercially available ultrasound probe for use as an alternative to X-ray scanning during treatment for these patients. The study will also aim to compare the likelihood of reducing side-effects and successfully treating the disease for the different adaptive strategies that are used around the world.

RATIONALE: Studying quality of life in patients with bladder cancer may help determine the long-term effects of bladder cancer and may help improve the quality of life for patients in the future. PURPOSE: This clinical trial is studying quality of life in patients with bladder cancer.

This is a single centre, single arm feasibility study assessing the feasibility of using computer vision methods to recreate the 3D bladder shape and to then map the cystoscopy images onto this bladder shape. If feasible, this 3D reconstructed shape would be spatially registered to radiological images (CT, MR) that are then used during radiation treatment planning. This analysis would not be used for making any clinical treatment decisions on the patient.

This is an open-label, expanded access protocol to continue administration of bemarituzumab (FPA144) in a single patient with recurrent bladder cancer

This will be a prospective trial comparing the perspective gross morphological of bladder tumor assessment done by outpatient flexible cystoscopy performed by resident, inpatient rigid cystoscopy done by senior staff and their prediction of the degree of invasion of bladder tumor plus the prediction of the grade compared with the standard pathological result. Also, assessment of the patient reported outcomes after both flexible and rigid cystoscopy will be done. In the long run of the study, the prognostic gross morphology with recurrence, progression and cancer specific survival will be assessed.

In patients with non-muscle-invasive bladder cancer, the development and introduction to the clinical practice of an adequately accurate biomarker may allow to limit the indications for performing control cystoscopy. Thus, it will reduce the discomfort and stress of patients, the risk of complications of the invasive procedure and probably significantly reduce the costs incurred by healthcare systems. The aim of the present study is to determine the usefulness of the determination of MCM5 protein expression in the urine of patients with urinary bladder or upper urinary tract cancer.

Malignant tumors of biliary system lack standard treatment and precise prognosis assessment methods. This study including 12 hospitals, collecting clinical and follow-up data of patients with biliary malignant tumors including cholangiocarcinoma and gallbladder carcinoma in recent 10 years, aim to build a special disease database, then use Bayesian networks and importance theory to establish a mathematical model to assess treatment strategies and prognosis accurately. At the same time, data on biliary malignant tumors newly treated by multicenters from 2018 to 2020 will be included to validate, adjust and refine the models to guide clinical individualized precise treatment.
