血管内皮生长因子-C及基质金属蛋白酶-2在肺腺癌中表达探究【摘要】 目的 探讨血管内皮生长因子-C(VEGF-C)与基质金属蛋白酶-2(MMP-2)在肺腺癌组织中表达及其与肺腺癌生物学行为的关系。方法 应用免疫组织化学染色(SP法)分别检测62例肺腺癌组织中VEGF-C和MMP-2的表达情况,根据不同的临床条件(肿瘤分期、分化程度、淋巴结转移,肿瘤部位、患者年龄)分别进行分组研究VEGF-C、MMP-2表达与非小细胞肺癌的侵袭、转移,术后生存期的关系。结果 62例肺腺癌中有34例VEGF-C表达阳性,阳性率为52.3%,38例MMP-2表达阳性,阳性率为58.5%。VEGF-C蛋白的表达与肿瘤的部位、淋巴结转移、分期、分化程度、生存期有关(P<0.05),与性别无关。MMP-2蛋白的表达与肿瘤的部位、淋巴结转移、分期、分化程度、生存期有关(P<0.05),与性别无关。VEGF-C和MMP-2蛋白的表达呈正相关(r0.477,P<0.01)。结论 VEGF-C、MMP-2在肺腺癌组织中的表达与肿瘤部位、肿瘤分期、分化程度、淋巴结转移,术后生存期有关,与患者年龄无相关性。VEGF-C和MMP-2高表达的肺腺癌患者容易出现淋巴结转移预后不良。

【Abstract】 Objective To explore the-C of vascular endothelial growth factor (VEGF-C) and matrix metall oproteinase-2 (MMP-2) expression in lung adenocarcinoma tissue and its relationship with biological behavior of lung adenocarcinoma.Methods Application of immunohistochemical staining (SP method) respectively in 62 cases of pulmonary adenocarcinoma tissue expression of VEGF-C and MMP-2, depending on the clinical conditions (lymph node metastasis in cancer staging, differentiation, and tumor site, patient age) Group research VEGF-C, respectively MMP-2 expression and invasion and metastasis of non-small cell lung cancer, after lifetime relationship.Results In 62 cases of adenocarcinoma of the lung, 34 cases of expression of VEGF-C-positive, positive rate of 52.3%, 38 cases of expression of MMP-2-positive, positive rate of 58.5%. Expression of VEGF-c and lymph node metastasis in tumor, location, staging, differentiation, lifetime related (P
1.3 判定标准 VEFGF-C和MMP-2蛋白均表达于细胞质(呈棕色)在高倍镜下取4个不同视野计数200个癌细胞,阳性细胞数>10%为阳性,阳性细胞数≤10%为阴性。
1.4 统计学方法 所有数据统计处理均在计算机统计软件SPSS 17.0上分析,率的比较采用χ2检验,生存分析采用Kaplan-Meier曲线。
