Early stage bladder cancer is typically treated with surgery (transurethral resection) followed by chemotherapy or immunotherapy delivered directly into the bladder. Muscle-invasive bladder cancer may be treated with surgery (partial or total cystectomy), sometimes preceded or followed by chemotherapy and/or radiation. For advanced or unresectable bladder cancer, options include chemotherapy, radiation alone, or chemoradiation. Bladder preservation protocols use chemoradiation to attempt curing the cancer without surgery. Radiation is also used post-operatively or palliatively to treat symptoms.
