摘要
目的分析汉族及维吾尔族女性三阴性乳腺癌(TNBC)患者组织中E-钙黏蛋白(E-cadherin,E-cad)、血管内皮生长因子(vascular endothelial growth factor,VEGF)的表达情况,了解其与预后间的关系。方法选择新疆医科大学附属肿瘤医院2008年3月—2010年3月汉族TNBC患者140例,维吾尔族57例,检测E-cad、VEGF的表达情况,并与淋巴结转移及TNM分期、组织学分级进行比较,同时观察两组5年无瘤生存率。结果两组TNBC患者5年无瘤生存率差异无统计学意义(P>0.05);E-cad的表达无差别,VEGF阳性率汉族低于维吾尔族(P<0.05),同时,两组E-cad的表达与淋巴结转移、TNM分期及组织学分级呈负相关(-1≤r<1,P<0.05),而VEGF的表达与淋巴结转移及TNM分期呈正相关(0<r<1,P<0.05),但与组织学分级没有明显关系。结论 E-cad在汉族与维吾尔族TNBC中没有表达差异,VEGF阳性率在汉族女性TNBC中低于维吾尔族,但两组5年无瘤生存率没有明显差别,提示维吾尔族TNBC患者可能存在与汉族患者不同的影响其预后的因素,需采取进一步研究证实。
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≤r1, P〈0.05）, while VEGF expression were positively associated with lymph node metastasis and TNM stage（0r1, 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.
