Erratum to: Breast Cancer Res Treat (2016) 160:153–162 DOI 10.1007/s10549-016-3982-x

In the original publication of the article, the last two sentences in the results of abstract were published incorrectly. The corrected sentences should read as below:

Radiotherapy after breast conserving surgery, used in 86.2 % of non-MDC patients, was administered to 90.2 % of MDC (p < 0.001) and 92.6 % of MDCSD (p = 0.096) patients. Post-mastectomy radiotherapy was administered in 52.0 % of non-MDC patients, 63.8 % of MDC (p = 0.050), and 89.1 % of MDCSD (p = 0.011) patients after propensity score adjustment.

The authors apologize for this error.
