Background/Aim: To evaluate outcomes in patients with low-risk prostate cancer treated with hypofractionated radiotherapy (HyRT). Patients and Methods: Between April 2004 and December 2015, 175 patients with low-risk prostate cancer were treated with HyRT 60 Gy in 20 fractions with or without image guidance and reduction of margin from clinical target volume to planning target volume. Results: The median follow-up was 66 months. The 8-year overall survival for the whole patient cohort was 88.9%. The 8-year biochemical no evidence of disease was higher in patients treated with image-guided HyRT (98.8% vs. 88%, p=0.023). During treatment, patients treated with image-guided HyRT presented a lower rate of grade 1-2 gastrointestinal toxicity (25.3% vs. 42.2%, p=0.001). At the last follow-up, the grade 1 Gastro-intestinal toxicity rate was 4.0% and the grade 1-2 genito-urinary toxicity rate was 25.1%. Conclusion: Our study demonstrated the efficacy of the schedule used with a low rate of acute and late toxicities. Therefore, reduction of margins with image-guided HyRT is safe.
