Filter by:The investigators compare the recurrence rate difference between two years after transurethral resection of the bladder tumor according to the method of anesthesia. Anesthetic methods are general anesthesia and spinal anesthesia. Assessment of recurrence is assessed by bladder endoscopy, CT, and pathological examination of surgical specimens.
Is BladderLight® (BL) urine testing accurate, as a non-invasive method, to exclude presence of bladder cancer in patients.
The standard non-surgical treatment for muscle invasive bladder cancer is concurrent chemo-radiotherapy. This treatment is associated with long term side effects in around a third of patients with up to 12% suffering from grade 3-4 toxicity. Effective radiotherapy depends on delivering a curative dose to the target whilst minimising dose to surrounding tissues to reduce toxicities. As an organ that constantly varies in shape and position, achieving this in bladder irradiation is challenging. Cone beam Computed Tomography (CBCT) has allowed visualisation of soft tissue on treatment and hence image-guided treatment and improved accuracy, but the image quality of CBCT is suboptimal for distinguishing soft tissue boundaries. On the other hand, MRI scans produce superior soft tissue definition and visualisation of tumour bed. This would in turn allow for various ways of optimising treatment and potentially improving outcome. There have been a number of studies evaluating pelvic organ motion in bladder cancer as well as assessing different adaptive radiotherapy strategies. These have included individualized margins, plan of the day and adaptive techniques. Most of these studies have been carried out using CBCT imaging which is often poor quality with limited soft tissue contrast. MRI offers better visualization of the tumour bed and organs at risk (OARs). As a result, the utilisation of MRI in radiotherapy could allow for increased radiation dose to the tumour bed while maintaining minimal dose to surrounding soft tissue. This study will explore the role of MRI imaging in adaptive radiotherapy for bladder cancer with development of a number of theoretical treatment strategies.
Trimodal prehabilitation is a preoperative three-tiered (trimodal) approach to optimizing physical and mental health. It has been found to successfully improve functional recovery in patients undergoing colorectal surgery following an evidence-based enhanced-recovery pathway (ERP). It is unknown whether the same program is effective in patients undergoing a similar surgery for bladder cancer (radical cystectomy). Objective: To evaluate the appropriateness of a standardized prehabilitation program for implementation into an enhanced recovery pathway for cystectomy patients and determine whether prehabilitation facilitates earlier recovery of functional capacity. Hypothesis: Prehabilitation will ultimately improve recovery of functional capacity, clinical and patient-centered outcomes in patients undergoing radical cystectomy for bladder cancer. Design: Participants will follow an 8-week trimodal prehabilitation program consisting of exercise therapy combined with nutritional counseling, protein supplementation, and psychological care; they will be compared to a cohort of participants following ERP care alone. Conclusion: The proposal will provide insight into the feasibility and effectiveness of trimodal prehabilitation for radical cystectomy patients and may ultimately lead to improved clinical outcomes and reduced morbidity.
To evaluate the short term results of chemoradiation in case of T1G3 BC after BCG failure.
• Bladder cancer is the most common malignancy of the urinary tract. It represents the 7th most commonly diagnosed cancer in male population worldwide and drops to the 11th when both genders are considered . According to the American cancer society's estimates of bladder cancer in 2017, the number of the new cases of bladder cancer is 79,030, and the mortality figures reached 16,870 .
This study is to verify the short-term efficacy and long-term prognosis of thulium laser resection compared with conventional transurethral resection of non-muscular invasive bladder cancer. Half of participants will receive thulium laser resection of bladder cancer, while the other half will receive electrical transurethral resection of bladder cancer.
This study evaluates the accuracy of Confocal Laser Endomicroscopy (CLE) in the diagnostic of non-invasive flat and exophytic bladder neoplasia. CLE results are compared to histopathology results.
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.
This study is designed to test the effectiveness of diclofenac suppositories in the prophylaxis of side effects caused by BCG bladder irrigations in bladder cancer patients.
