OBJECTIVES
The aim of our study is to compare the expression of CD44S with well known prognostic factors as a lymph node status and eostrogen, progesterone in breast carcinoma.

METHODS
The study was performed with the cell blocks of 40 patients with breast carcinoma. Six patients with benign lesions were used as control. Immunocytochemistry staining method was applied to the sections prepared from the cell blocks. Slides were evaluated and correlations between CD44S positivity and lymph node metastasis and other parameters.

RESULTS
CD44 positivity were detected in 29 cases and 11 cases negative. All of the cases in the control group were positive for CD44S anitbody. No statistically significant correlations were established between CD44S expressions and other parameters.

CONCLUSION
As a result of this study it is concluded that CD44S expression has no realtionship with lymph node metastasis, eostrogen and progesterone positivities in breast carcinoma. Keywords : CD44S; lymph node metastasis; breast carcinoma
