Brief Summary: The investigators aim to investigate a possible role for radiotherapy in good prognosis bladder cancer patients has been identified as a possible alternative to cystectomy especially for patients non-eligible for surgery but has yet to be fully explored
Detailed Description: Bladder cancer is the tenth most commonly diagnosed cancer with urothelial carcinoma representing 90 of all bladder cancer cases Approximately three-quarters of patients diagnosed with urothelial carcinoma have non-muscle invasive disease NMIBC confined to the mucosa stage Ta or carcinoma in situ CIS or submucosa stage T1 The gold standard for diagnosing CIS is a combination of cystoscopy urine cytology and histological evaluation Diagnosis and resection of visible TaT1 tumors is done by transurethral resection of bladder tumors TURBT Standard treatment for patients with high-risk NMIBC high-grade Ta CIS or any T1 following staging consists of intravesical Bacillus Calmette-Guerin BCG immunotherapy BCG even administered optimally does not provide absolute protection BCG failure is generally considered recurrence or progression during therapy Clinical trial data comparing salvage therapies after BCG are quite heterogeneous in part due to inconsistent definitions and reporting methods

Patients who are BCG-unresponsive have a 20-40 risk for progression to muscle-invasive bladder cancer within 5 years which carries a 50 risk for the development of incurable metastatic disease

Interestingly although chemoradiotherapy is a recognized standard of care in muscle-invasive bladder cancer MIBC it has not been adequately explored in NMIBC However the available data suggests that NMIBC is a radioresponsive malignancy and that in a proportion of patients bladder preservation would be possible

The investigators aim to evaluate the use of radiotherapy in patients with high-grade non-muscle-invasive bladder cancer who have BCG failure potentiating its effect with commonly use radiosensitizers
