The age of patients, stage in the TNM classification, histology, grade of tumors and HER 2/neu (HER2), estrogen receptor (ER), progesterone receptor (PR), and nuclear protein Ki67 (MIB-1) percentage of immunostained cells are listed for each patient. The patients constituting the metastase positive group are in bold.
