T0: No evidence of primary tumor. T1: Tumor measuring 20 mm or less in greatest dimension.
T2: Tumor measuring more than 20 mm, but not more than 50 mm in greatest dimension.
T3: Tumor measuring more than 50 mm in greatest dimension. N0: No regional lymph node
metastasis is identified or isolated tumor cell clusters (ITCs) are identified only.
N1: Tumor with micrometastases; or metastases in 1-3 axillary lymph nodes; and/or
clinically negative internal mammary nodes with micrometastases or macrometastases
by sentinel lymph node biopsy. N1mi: Micrometastases (approximately 200 cells, larger
than 0.2 mm, but none larger than 2.0 mm). N2: Tumor with metastases in 4-9 axillary
lymph nodes; or positive ipsilateral internal mammary lymph nodes by imaging in the
absence of axillary lymph node metastases. G1: Low combined histologic grade (favorable);
SBR score of 3-5 points. G2: Intermediate combined histologic grade (moderately favorable);
SBR score: 6-7 points. G3: High combined histologic grade (unfavorable); SBR score
of 8-9 points. M0: No clinical or radiographic evidence of distant metastases. Imaging
studies are not required to assign the M0 category. (AJCC 8th ed.);
