Brachytherapy in cancer of the prostate: an historical perspective.
Carcinoma of the prostate in the United States has increased dramatically in the last few years due to improved detection methods including prostatic specific antigen testing and transrectal ultrasound. More than half of all prostate cancers are discovered while still localized. Radical prostatectomy and definitive radiation are reserved for patients in good health, who have localized disease. Brachytherapy, with its inherent ability to deliver a high dose to an organ-confined tumor, while minimally irradiating the surrounding tissues, has successfully competed with external beam for the treatment of early prostatic tumors. Their respective role is constantly under scrutiny and re-evaluation to improve the accuracy of delivery of radiation. The present review focuses on the role of brachytherapy for treatment of early cancer of the prostate over the span of this century and its future in the next millennium.
