Abstract：【Objective】To investigate the expression and clinical significance of PAX2, AIB1 and MTDH in breast cancer (BC) patients. 【Methods】A total of 200 patients with breast discomfort who underwent pathological examination in our hospital were selected. According to the pathological diagnosis, patients were divided into the breast cancer group and the benign breast lesion group. The expressions of PAX2, AIB1 and MTDH in the two groups were recorded. Furthermore the expression levels of PAX2, AIB1 and MTDH in breast cancer patients with different clinicopathological characteristics were compared. 【Results】The positive expression rate of PAX2 was lower in breast cancer tissue, while the positive expression rates of AIB1 and MTDH were both higher in breast cancer group. The differences were statistically significant (P<0.01). The positive expression rate of PAX2 was lower in breast cancer patients with moderate or low differentiation, lymph node metastasis and infiltration depth staging T3+T4 (P<0.01).The positive expression rates of AIB1 and MTDH in breast cancer patients with moderate or low differentiation, lymph node metastasis and infiltration depth staging T3+T4 were higher (P<0.01). There was no significant difference in the positive expression rates of PAX2, AIB1, and MTDH in breast cancer patients of different ages (P>0.05). Regression analysis results showed that lymph node metastasis and depth of infiltration were the factors affecting the expression of PAX2, AIB1 and MTDH in breast cancer. 【Conclusion】PAX2 positive expression rate is lower in breast cancer patients, while AIB1 and MTDH positive expression rates are higher. Also those expression rates are closely related to lymph node metastasis and depth of infiltration.
