Material And Methods: Of a total of 50 patients treated between 2011 and 2017, 29 were men and 21 were women, and the mean age was 62 years (median 66 years, range 25-81 years). Patients were most often irradiated in five fractions; the dose was selected according to dose-volume histograms of organs-at-risk in proximity to the planning target volume.
