摘　　要：目的探讨细胞黏附分子变异体6(cell adhesion molecule variant 6,CD44v6)、黏蛋白1(mucin-1,MUC1)及血管内皮生长因子(vascular endothelial growth factor,VEGF)在三阴性乳腺癌中的生物学特征及其对预后评估的意义。方法选取2014年2月至2016年3月在黄冈市中心医院确诊的65例三阴性乳腺癌患者和75例非三阴性乳腺癌患者为研究对象,空腹抽取静脉血3 m L,采用酶联免疫吸附法(ELISA)检测血清CD44v6、MUC1及VEGF表达水平。结果三阴性乳腺癌患者的CD44v6(338.57±51.37)pg·m L-1和MUC1(156.32±34.71)pg·m L-1表达水平与非三阴性乳腺癌患者的CD44v6(327.68±51.14)pg·m L-1和MUC1(153.56±35.12)pg·m L-1表达水平比较,差异无统计学意义(P>0.05);而三阴性乳腺癌患者的VEGF(86.91±32.46)pg·m L-1表达水平明显低于非三阴性乳腺癌患者(205.14±53.17)pg·m L-1表达水平,差异有统计学意义(P<0.01)。三阴性乳腺癌患者的CD44v6、MUC1及VEGF表达水平与年龄、肿瘤大小、组织分级、临床分期和淋巴转移均无明显相关性(P>0.05)。CD44v6与MUC1表达水平呈正相关(r=0.224,P=0.015),与VEGF表达水平无相关性(r=0.023,P=0.637),MUC1与VEGF表达水平呈正相关(r=0.271,P=0.008)。结论三阴性乳腺癌患者的血清VEGF表达水平较低,血清CD44v6和MUC1表达水平无明显变化,MUC1分别与CD44v6和VEGF呈正相关,但三者均与年龄、肿瘤大小、组织分级、临床分期和淋巴转移等预后指标无明显相关性,对预后评估无重要意义。Objective To investigate the cell adhesion molecule variants of variant 6 （CD44v6）,mucin 1 （MUC1） and vascular endo-thelial growth factor （VEGF） biological characteristics in triple-negative breast cancer and its significance in the prognosis evaluation . Methods Sixty-five cases of triple-negative breast cancer patients and 75 cases of non-triple-negative breast cancer,diagnosed in Huanggang Central Hospital from February 2014 to March 2016,were selected as the research objects .The venous blood was drawn by 3 mL on empty stomach,and enzyme-linked immunosorbent assay （ELISA） was adopted to detect serum CD44v6,MUC1 and VEGF ex-pression levels.Results CD44v6 expression level was （338.57 ±51.37） pg· mL-1 and MUC1 expression level was （156.32 ± 34.71） pg· mL-1 in triple-negative breast cancer patients ,while in non-triple-negative breast cancer patients ,CD44v6 expression level was （327.68 ±51.14） pg· mL-1 and expression level of MUC1 was （153.56 ±35.12） pg· mL-1;the difference was not statistically significant （P 〉0.05）.The expression level of VEGF （86.91 ±32.46） pg· m-1 in triple-negative breast cancer patients was signifi -cantly lower than that of non-triple-negative breast cancer patients （205.14 ±53.17） pg· mL-1 ,and the difference was statistically significant （P 〈0.01）.The expression levels of CD44v6,MUC1 and VEGF in patients with triple-negative breast cancer had no signifi -cant correlation with age,tumor size,histological grade,clinical stage and lymph node metastasis （P 〉0.05）.CD44v6 was positively correlated with MUC1 expression level （r =0.224,P =0.015）,and had no correlation with VEGF expression level （r =0.023, P =0.637）.MUC1 was positively correlated with VEGF expression level （r =0.271,P =0.008）.Conclusions The serum VEGF expres-sion level of triple-negative breast cancer patients was low ,the expression level of serum CD44v6 and MUC1 was not significantly changed,and MUC1 was positively correlated with CD44v6 and VEG
