Brief Summary

The benefit of dose escalation in radiotherapy (RT) for biochemical control of prostate cancer is a clearly established fact based on the results of different published prospective trials. This benefit, acquired with three-dimensional conformal radiation technique is counterbalanced by an increase in urinary and gastrointestinal toxicity. The joint progress of dose planning systems and multileaf collimators (MLC) technology have enabled the Intensity Modulated Radiation Therapy (IMRT). Recently the contribution of "spacers" positioned in the septum between the rectum and the prostate could improve the functional results of IMRT in terms of rectal toxicity. The aim of the investigators study is to assess the dosimetric gain from the contribution of the implantable BioProtect balloon on organs at risk.
