Sequential Chemotherapy Followed by Radiotherapy Versus Concurrent Chemo-Radiation in Muscle Invasive Bladder Cancer.

Bladder cancer is diagnosed at older age compared to all other known cancer types. Radical cystectomy after neoadjuvant chemotherapy or tri-modality treatment (consist of TURB, concurrent chemo-radiation) are the standard treatments. Many of the patients cannot receive tri-modality treatment (concurrent chemo-radiation) because of medical comorbidities. The present study assessed the results of sequential use of chemotherapy and radiotherapy versus concurrent use of them in 266 muscle invasive bladder cancer patients. The results showed similar overall survival but lower disease-free survival in the sequential group. Recurrence rate was higher in the concurrent group. The results showed that sequential use of chemotherapy and radiotherapy provides comparable results to concurrent use of them and provides better results than less than tri-modality treatments.
