Preferred Label : Stage IB;
NCIt definition : Invasive cancer confined to the original anatomic site of growth without lymph node
involvement. The definition of stage IB depends on the particular type of cancer that
it refers to; for example, for breast cancer, stage IB is defined as follows: (T0,
N1mi, M0); (T1, N1mi, M0). T0: No evidence of primary tumor. T1: Tumor 20 mm or less
in greatest dimension. T1 includes T1mi. T1mi: Tumor 1 mm or less in greatest dimension.
N1mi: Nodal micrometastases. M0: No clinical or radiographic evidence of distant metastasis.
M0 includes M0(i ); for bone cancer, stage IB is defined as follows: (T2, N0, M0,
G1, G2, GX); (T3, N0, M0, G1, G2, GX). T2: Tumor more than 8 cm in greatest dimension.
T3: Discontinuous tumors in the primary bone site. N0: No regional lymph node metastasis.
M0: No distant metastasis. G1: Well differentiated-low grade. G2: Moderately differentiated-low
grade. GX: Grade cannot be assessed. (partially adapted from AJCC 7th ed.);
