ABSTRACT
OBJECTIVE:
To study the expression and clinical significance of MTDH and VEGF in triple-negative breast cancer (TNBC).METHODS:
Tissue samples of 168 breast cancers (including 112 TNBC tissue and 56 non-TNBC tissue), 10 breast fibroadenomas and 15 normal breast tissues were collected. Postoperative specimens were examined by immunohistochemistry for MTDH and VEGF expression. The correlation between the expression of MTDH and VEGF and clinicopathological features was analyzed.RESULTS:
MTDH and VEGF were expressed in 57.1% and 49.4% of breast cancer patients, 64.3% and 56.3% in TNBC patients, respectively, significantly higher than that in the non-TNBC tissues, breast fibroadenomas and normal breast tissues (P<0.05 for all). Statistically significant correlation was found between the MTDH and VEGF expressions (r=0.356, P<0.001). Moreover, MTDH expression was correlated with tumor size, BMI index, lymph node metastasis, pathological stage, recurrence and metastasis, and the expression of p53 and Ki-67 proteins (P<0.05 for all). The VEGF protein expression was correlated with lymph node metastasis, pathological staging, recurrence and metastasis, and the expression of Ki-67 protein (P<0.05 for all). The patients with high expression of MTDH and VEGF showed a lower DFS and OS (P<0.05 for both).CONCLUSIONS:
MTDH and VEGF expression may be correlated with tumor angiogenesis and progression and has the potential to be valuable prognostic factors in patients with TNBC.
