ABSTRACT |
Purpose : Sentinel lymph node (SLN) biopsy allows to identify the first lymph node into which a primary tumor
drains. In breast cancer, identification of tumor cells in SLNs is one of the strong predictor of disease-free and
overall survival for breast cancer patients. Its immunologic nature has been identified or established, and would
provide us useful prognostic or predictable information on clinical outcome.
Meterial and Methods : We performed immunohistochemical analysis of 149 SLN from 41 early breast cancers
(T1/T2 and N0) between 2000 and 2003 at OOO University for 5 years. They had followed to determine
immunoprofile alterations of CD4 helper, CD8 cytotoxic T cell and CD1a dendritic cell population whether they can
predict distant metastasis or disease-free survival. Classical prognostic factors-tumor size, pathologic diagnosis,
histological grade and nuclear grade were compared.
Results : Immunohistocheminal expression of SLN appear independent of ER and PR, C-erbB2. Immunoprofile
changes and clinical manifestation represent independent processes. Although more patients were alive at the 5-
year time point in the group with higher CD4 helper, CD8 cytotoxic T cell and CD1a dendritic cell population, this
failed to reach statistical significance at the p= 0.05 level. The larger the tumor size is, the more the expression of
CD1a, CD8 in SLN is increased(p-value =0.01/0.03).
Conclusion : The expression of CD1 and CD8 correlatated primary tumor size of breast cancer. These finding
demomstrate that immune-activity of primary tumor influence tumor-draining lymph node. Analysis for long term
follow-up post surgery is required to investigate the association further. |
