The addition of radiotherapy (RT) to breast-conserving surgery (BCS) is common clinical practice in the treatment of patients with ductal carcinoma in situ (DCIS). The objective of this meta-analysis is to assess the cumulative evidence of the benefit of RT in this situation. The analysis includes all available English-language randomized controlled trials (RCT) comparing outcomes in patients who received BCS alone and those who received BCS and RT.
