Aim: To evaluate the predictability of toxicity analyzing the dose-volume histograms (DVHs) and to verify the effectiveness of preventive measures limiting side toxicity considering the evolution of the radiation techniques for prostate cancer treatment. Materials and Methods: 208 patients with localized prostate cancer were treated with exclusive radiotherapy until 73.8 Gy (group A) or 79.2 Gy (group B) with the dose escalation technique. Preventive measures to minimize the side effects were

Valuating the treatment plans, we found that most of the patients developing toxicity had "borderline" DVHs. Conclusion: Our analysis led to the establishment of a protocol for the management of patients with "border-line" DVH.
