External beam radiotherapy (RT) is used to treat all stages of localized prostate cancer. Using a 3D conformal RT (3DCRT) without any androgen deprivation, a clear dose-effect relationship has been shown in terms of both biochemical control and also unfortunately of rectal and urinary toxicity. Compared to a "standard" 3DCRT, intensity modulated RT (IMRT) improves the dose distribution by mainly providing concave dose distribution and tight dose gradients. Based on large clinical experiences for at least one decade, IMRT is widely used to increase the dose in the prostate and therefore local control, without increasing toxicity. Indeed, toxicity rates observed after high dose delivered in the prostate (80Gy) with IMRT appear no different than those observed after a standard dose (70Gy) delivered by a standard 3DCRT. Arc IMRT appears a new promising IMRT modality, decreasing dramatically treatment duration. However, this IMRT-based dosimetric benefit may not be translated into a full clinical benefit, if intra-pelvic prostate motion is not taken in account. Image-guided radiotherapy (IGRT) should be therefore associated with IMRT for a maximal clinical benefit. This article is a literature review showing the interest of both combined approaches.
