There is growing interest in the use of proton-beam radiation therapy for the treatment of prostate cancer. Although the dose distribution of this form of charged-particle radiation has the potential to improve the therapeutic ratio of prostate radiation, allowing for an increase in dose to the tumor without a substantial increase in side effects, no randomized controlled trials have been reported that compare its efficacy and toxicity with those of other forms of radiation therapy.
