Benchmarks achieved in the delivery of radiation therapy for muscle-invasive bladder cancer
چکیده انگلیسی

Radiation therapy has a multifaceted role in the treatment of muscle-invasive bladder cancer, from being a component of bladder sparing regimens to adjuvant therapy for patients after partial cystectomy, to palliative treatment in patients with metastatic disease. Here, we review the techniques currently used and the settings in which these techniques are applied. Advances in imaging and radiation delivery have allowed for definition of more precise treatment volumes, permitting the delivery of higher tumor doses and lesser doses to critical targets. Better tumor control, fewer therapeutic complications, and better quality of life outcomes are anticipated. In the United States, the most rapidly growing use of radiation in the treatment of bladder cancer is as a component of selective bladder conservation. It uses trimodality therapy, consisting of a maximal transurethral resection followed by concurrent chemotherapy and radiation. Careful cystoscopic surveillance by an experienced urologist ensures a prompt cystectomy at the fist sign of treatment failure. The majority of patients retain a well-functioning bladder with no survival decrement. Radiation therapy is also used as adjuvant therapy after partial cystectomy in select patients. In this setting, it decreases the risk of local or incisional recurrence. It is also used in patients with pelvic recurrences after cystectomy, often combined with concurrent chemotherapy. Radiation is a very effective palliative agent for patients with locally advanced or metastatic disease. It can palliate bleeding and pain for patients with local progression or alleviate pain from bony metastases.
