To assess acute and late toxicity of hypofractionated radiotherapy, its efficacy and impact on quality of life in patients with low-risk prostate cancer. Since August 2006 to October 2007, 15 prostate cancer patients with favorable clinical features, aged 54-74 years (mean 67 years) entered the study. Tumor stage in the majority (73%) of patients was T2a, the mean pretreatment PSA value was 7.2 ng/ml (range 5-10.9 ng/ml). The study group was treated 3 times a week with 4 Gy per fraction to the total dose of 60 Gy within 5 weeks. 3D conformal treatment planning was used with no fiducial markers. Acute and late toxicity was evaluated using modified EORTC/RTOG/LENT scoring systems. Patients regularly filled the EORTC QLQ-PR25 questionnaires. All patients completed radiotherapy according to the plan. During radiotherapy, 26% of patients had grade 1-2 rectal symptoms. The incidence of acute urinary toxicity score was 26%, 60%, and 14% for grade 0-1, 2 and 3, respectively. One year after ...
