Objective: To explore the expressions of FHIT (Human fragile histidine triad), BCRP (breast cancer resistance protein) and Bcl-2 proteins in breast invasive ductal carcinoma (IDC) and its relationship with clinical pathological factors. Methods: The expressions of FHIT, BCRP and Bcl-2 proteins in 84 cases of intraoperative resection of primary breast IDC and 36 cases of normal breast tissue about 3 cm away from the neoplastci foci were detected with the method of immunohistochemical streptavidin-peroxidase (SP) to analyze the relationship between the three proteins and the pathological features of breast IDC. Results: The positive expression rates of FHIT, of BCRP and Bcl-2 were 42.86%, 72.62% and 61.90% respectively in the breast IDC group and 72.22%, 36.11% and 38.89 % respectively in the normal breast tissue control group, between which the differences were statistically significant (P <0.05). In the IDC group, the expression of the three proteins was related to the lymph nodes metastasis and tumor recurrence of breast IDC, but was not significantly correlated with the expression of estrogen receptor (ER), progesterone receptor (PR) and proto-oncogene human epidermal growth factor receptor 2 (Her-2). The expression of FHIT was negatively correlated with the expression of and Bcl-2 (r = -0.322, -0.389), but BCRP and Bcl-2 expression were positively correlated (r = 0.276). Conclusion: The abnormal expressions of FHIT, BCRP and Bcl-2 proteins in breast IDC may play an important role in its onset and development.
