  Aim: To compare Intensity Modulated Radiotherapy (IMRT) and Volumetric-Modulated Arc Radiotherapy (VMAT) for patients receiving moderate hypofractionated radiotherapy. Introduction: Hypofractionated radiation has been established for localized prostate cancer; however, eligibility for this treatment depends on strict dosimetric constraints. Methods: CT simulation datasets of 23 patients with localized prostate adenocarcinoma were analysed, IMRT and VMAT plans were generated for each patient. Dose Volume Histogram (DVH) records, Monitor Units (MUs), treatment delivery times, conformality, and homogeneity indices were compared between the two techniques. Hypofractionated regimen parameters were assessed for each technique to evaluate plan eligibility for the short-course radiotherapy (60 Gy over 20 fractions). Results: Compared with IMRT plans, VMAT resulted in better PTV coverage (p=0... Read More»
