Abstract

This article will review the role of hypofractionation for prostate cancer. Recent analyses and reviews of tumor control in prostate cancer have suggested an alpha/beta ratio value on the order of 1 to 3 for prostate cancer, which is somewhat lower than the value typically ascribed to the adjacent organs at risk, such as bladder and rectum. It would offer an opportunity to improve the therapeutic ratio by using a hypofractionation approach. The result of the latest study that was phase III randomized control trial, concluded that the hypofractionated regimen was superior to the conventional fractionation in terms of freedom from biochemical failure rate. In addition, the incidence of late toxicity was equivalent between the two groups. However, the optimal fractionation schedule in the treatment remains controversial
