Methods: The expression of HMGB1 protein in IDC breast tissue was detected by immunohistochemistry, and the relations among size of tumour, lymph node metastasis, clinical staging, estrogen receptor(ER), progesterone receptor(PR) and human epidermal growth factor receptor 2(HER-2) were also analyzed. Results: Fortysix cases out of 60 cases of IDC breast tissue showed positive or strong positive HMGB1 expression(76.67%), statistical significance was observed between HMGB1 expression with clinical staging(P < 0.01), lymph node metastasis(P < 0.01), breast cancer ER(P < 0.05) and HER-2(P < 0.05), however same conclusion can not be drawn between HMGB1 with either size of tumour or PR expression(P > 0.05) in IDC breast tissue. Spearman analysis showed negative correlation between HMGB1 expression and ER, and positive correlation between HMGB1 expression and clinical staging, lymph node metastasis together with HER-2. Conclusion: It's promising that HMGB1 expression in IDC tissue can be one of biological indicators of poor prognosis.展开更多
