  1. G1 = well differentiated tumor; G2 = moderatly differentiated tumor; G3 = poorly differentiated tumor (the three-tier grading system (G1-3) is usually used at our institution to determine the histologic grade of tumor tissue). T = tumor grade; N = nodal status; M = distant metastasis; L = invasion of lymphatic vessels; DCIS = ductal carcinoma in situ; ER = estrogen receptor; PR = progesterone receptor; n.d. = not done.
