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 gross hematuria.
This is a Phase I/II and multicenter study designed to evaluate the efficacy and safety of 4SCAR-T cells in participants with locally advanced or metastatic urothelial bladder cancer (UBC) who have no further treatment available.
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.
assess diagnostic performance of 3-Tesla DW-MRI in detecting and staging bladder cancer and potential role of the ADC value as a biomarker reflecting histological grade and stage.
Collect blood samples and associated clinical data prior to, during, and post radiation treatment.
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.
Bladder cancer is a common malignant tumor of the urinary system, radical resection plus urinary diversion is the first choice of treatment for muscle invasive bladder cancer. Urinary diversion of surgical options related to patient' survival and quality of life. In 1988, Hautmann firstly reported an orthotopic urinary diversion method: Hautmann neobladder. As the urine can be controlled from the original urethra, the patient's quality of life has been greatly improved, so the new bladder surgery gradually accepted and welcomed by urologists and patients. However, in order to achieve low-pressure and large-volume storage capacity of the urine reservoir, the 40-70cm long interception of terminal ileum need to be detubularized. Only after split, folded, re-stitched and a series of treatment, the intestinal can be used. Such complicated procedures make so many urologists give it up. In addition, the interception of the long ileum may lead to reduced absorption of vitamin B12 which caused anemia, metabolic acidosis, intestinal dysfunction. Not only that, as time goes by, this kind of neobladder will be unlimited expansion and resulting in a serious increase in residual urine volume, hydronephrosis, or even the occurrence of neobladder spontaneous rupture. In 2000, professor Chunxiao Liu invented "detaenial sigmoid neobladder", this surgical method overset the traditional intestinal detubularization approach, which detached the serosal layer with smooth muscle from the bowel without split it. This kind of neobladder is easier to construct and have less impact on intestinal function. So far, it has been implemented for more than 600 cases in Zhujiang hospital, the age of patients range from 9 months (bladder rhabdomyosarcoma) to 84 years old. So far as now, no multicenter prospective clinical study on orthotopic urinary diversion has been performed worldwide, neither the head-to-head studies on detaenial sigmoid neobladder and ileal neobladder. Our project is going to perform a multicenter randomized controlled trial for these two neobladder methods and look forward to assess the safety and efficacy of these two procedures which provide an objective basis for the patients undergoing orthotopic urinary diversion in the future.
This study evaluates the influence of premedication on cognitive functions in patients undergoing transurethral resection of bladder tumor under spinal anesthesia. The aims of premedication are anxiolysis, analgesia and the reduction of perioperative risk among the patients with comorbidities. The patients will be randomly allocated to receive premedication either with opioid solely or with benzodiazepine combined with opioid. The anesthetic technique is standardized.
To assess whether the addition of a bladder tumor biopsy improves the level of agreement between the pretreatment endoscopic impression and the final postoperative pathology determination of stage and grade in non-muscle-invasive urothelial carcinoma of the bladder.
