The role of the pathologist in the management of breast cancer

The pathologist is a consultant in breast cancer management whose
responsibility is to establish the histologic diagnosis of cancer as well
as its anatomic extent once sufficient tissue has been provided. The
consultation also provides data that may be used to aid in selecting
primary or adjuvant therapy, evaluating new therapies, estimating
prognosis, and assessing outcome. Examples of such data are the TNM
histopathologic classification of the anatomic extent of the cancer used
for the stage grouping (T = the extent of the primary tumor, N = the
absence or presence and extent of regional lymph node metastasis, and M =
the absence or presence of distant metastasis); tumor size, histologic
type, and histologic and/or nuclear grade; assessment of blood vessel and
lymphatic vessel invasion; analysis of steroid receptors, and other special
studies as appropriate.
