Background/aim: The aim of this study was to evaluate the treatment results of patients undergoing adjuvant radiotherapy (ART) after breast surgery with the diagnosis of ductal carcinoma in situ (DCIS).Materials and methods: A total of 61 women who had undergone radiotherapy following extensive surgical excision were enrolled. All patients underwent 50 Gy ART. Survival analysis was performed using Kaplan?Meier analysis and SPSS 20.0.Results: The median age was 52 years (range: 28?86). The median follow-up period after RT was 92 months (range: 23?237). The median overall survival and distant and regional recurrence-free and disease-specific survival was 96 months (range: 26?240), while disease-free and local recurrence-free survival was 96 months (range: 22?240). While the 15-year and 20-year overall survival rates were 87% and 87%, respectively, the recurrence-free survival rates were 98% and 98%, respectively; the rates of disease-specific survival were 100% and 100%, respectively.Conclusion: The results of this study with a long follow-up period have shown that ART in DCIS is an effective treatment method to provide local disease control. However, further large studies are needed to identify the prognostic factors.
