Abstract:
Objective To probe into the expression of E-cadherin(E-cad) and vascular endothelial growth factor (VEGF) in triple negative breast cancer(TNBC) patients of Han and Uygur, and their relationship with the prognosis.
Methods From March 2008 to March 2010, 140 cases of Han and 57 cases of Uygur TNBC patients were admitted. We determined the expression of E-cad and VEGF, compared them with lymph node metastasis, TNM staging and histological grade, and observed the 5-year disease-free survival(DFS).
Results 5-year DFS of two groups were not different (P > 0.05). E-cad expression of two groups were not different, and Han patients' VEGF positive rate was lower than Uygur patients (P < 0.05). E-cad expression were negatively associated with lymph node metastasis, TNM stage and histological grade (-1≤r < 1, P < 0.05), while VEGF expression were positively associated with lymph node metastasis and TNM stage (0 < r < 1, P < 0.05), but no significant relationship with histological grade.
Conclusion E-cad expression in the Han and Uygur TNBC patients were not different. The VEGF expression rate of TNBC in the Han group is lower than that in the Uygur group, but no significant difference in the 5-year DFS between two groups, considering Uygur TNBC patients may have different prognostic factors, which needs to take further study.
