Panel-Oncotype Dx Recurrence Score Less Than 11, T1-2, N0, M0, G1-3, HER2 Status:
Negative, ER Status: Positive, PR Status: Any). 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. N0: No regional lymph node
metastasis is identified or isolated tumor cell clusters (ITCs) are identified only.
N1mi: Micrometastases (approximately 200 cells, larger than 0.2 mm, but none larger
than 2.0 mm). 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.);
