BR Bloom Richardson grade
*Clinical M-stage was not explicitly reported, only when staging (PET CT) was performed
**In 7 patients, the pathologist reported that the tumor size was too small for BR grading and in one patient the BR grade was not reported
***In 367 patients, 48 were ER−, 316 ER+ and ER in 3 patients was not possible because of pTis status (no invasive tumor was found)
aIn case of breast-conserving surgery (n = 264), in 0 patient reasons for direct reconstruction were reported. In case of modified radical mastectomy (n = 103), in 29 patients reasons for immediate breast reconstruction were reported
