  1. 1Tumors were graded using the Nottingham combined histologic grading system.
  2. 2No gene amplification was detected by fluorescent in situ hybridization.
  3. 3A complete H-score was calculated by summing the products of the percentage cells stained at a given staining intensity (0–100) and the staining intensity (0–3).
  4. AC, accompanying changes; DCIS, ductal carcinoma in situ; E-CD, E-cadherin; ER, estrogen receptor; IDC, invasive ductal carcinoma, IDH, intraductal hyperplasia; ILC, invasive lobular carcinoma; LCIS, lobular carcinoma in situ; LN, lymph node; PgR, progesterone receptor.
