ABSTRACT: 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 recommended in group B. Results: The assessment of
genitourinary toxicity was similar while gastrointestinal toxicity was better
in group B. 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.
