Objective To investigate the expressions of C-erbB-2, estrogen receptor (ER) and progesterone receptor (PR) in breast cancer tissues and to explore their relationship with patients-age, tumor size, lymph node metastasis, histopathological type and the stage of cancer. Methods The expressions of C-erbB-2, ER and PR in 83 cases of breast cancer tissues were detected by immunohistochemistry and the clinical significance was statistically analyzed. Results The positive expression rate of C-erbB-2, ER and PR in 83 cases of breast cancer tissues were 78.3%, 56.6% and 55.4%, respectively. The expressions of C-erbB-2, ER and PR were not correlated to patients’ age, tumor size, histopathological type and the stage of cancer (Pgt;0.05). While the expression of C-erbB-2 rather than ER and PR was correlated to lymph node metastasis (P＜0.05) and the correlation was positive (r=0.387, P＜0.05). Conclusion The positive expression of C-erbB-2 is one of lymph node metastasis factors for breast cancer patients. Combined detection of ER and PR expression may be helpful to clinical treatment and predict prognosis for breast cancer patients.
