“(IMRT) has an advantage. The newer, high-dose, conformally directed, external-beam techniques for radiation therapy such as IMRT have been in widespread use for less than ten years; IGRT has been around for an even shorter time. However, some reports of long-term success are now emerging. New studies suggest that at ten years, high radiation doses alone can produce PSA control or cure rates in 93 percent of men with low-risk prostate cancer. What about more aggressive prostate cancer? As we discussed in chapter 9, the best treatment regimen for men with intermediate- and high-risk prostate cancer is still a moving target, but it will likely turn out to be a combination of high-dose radiation and short- or long-term hormonal therapy.”
