ABSTRACT
Objective To detect COX-2 expressions in primary tumor and axillary lymph node tissues of breast cancer,and to study the relationship between COX-2 expression in breast cancer and lymph node metastasis.Methods The expressions of COX-2 in 9 normal breast tissues,50 primary breast cancer tissues,19 positive axillary lymph nodes and 31 negative axillary lymph nodes were detected with immunohistochemistry S-P method.Results COX-2 staining was granular and localized to the cytoplasm of tumor cells.In normal breast tissues,COX-2 staining was granular and localized to mesenchymocyte.In negative lymph nodes,COX-2 staining was granular and localized to macrophagus cytoplasm.The positive expression rates of COX-2 in normal breast tissues,primary breast cancer tissues,positive axillary lymph nodes and negative axillary lymph nodes were 11.1%,60.0%,84.2%,and 32.3%,respectively.There were significant differences of COX-2 positive expression rates between normal breast tissues,primary breast cancer tissues and positive axillary lymph nodes(P
