  1. aAll information given refer to the primary tumor
  2. b5 of 303 patients are bilateral primary BC, so we deal with the tumor as individual one (n = 308)
  3. cNST include the formerly called “Invasive ductal” and “other” types
  4. dLocal recurrence has been detected during the follow-up of 40 patients (1 of them are bilateral BC, so n = 41)
  5. eDistant metastasis has been detected during the follow-up of 58 patients (2 of them are bilateral BC, so n = 60)
