  1. Data are presented as number of patients (%) or median (interquartile range)
  2. aMissing data: age (n = 1), race (n = 1), stage (n = 23), grade (n = 4), ER (n = 21), PR (n = 22), HER2 (n = 37), TNBC (n = 23), LVI (n = 14), and node-positive status (n = 10). Percentages are calculated from the total number of patients with known values
  3. IDC, invasive ductal carcinoma; ILC, invasive lobular carcinoma; ER, estrogen receptor; PR, progesterone receptor; HER2, human epidermal growth factor 2; TNBC, triple-negative breast cancer; LVI, lymphovascular invasion
