胃癌组织中VEGF-D的表达与MLVD的相关性研究

目的:检测胃癌患者肿瘤组织血管内皮生长因子(VEGF)-D的表达及微淋巴管密度(MLVD),分析VEGF-D与MLVD的关系。方法:收集52例胃癌术后患者标本,采用免疫组化方法测定胃癌、癌旁和正常组织MLVD及VEGF-D的表达。结合临床及病理资料,分析VEGF-D与MLVD、年龄、性别、肿瘤组织分化、淋巴结转移以及分期之间的关系。结果:VEGF-D在胃癌、癌旁与正常组织的阳性表达差异有统计学意义(P<0.01),而在胃癌与癌旁组织两者间的阳性表达差异无统计学意义。有淋巴结转移和Ⅲ、Ⅳ期患者胃癌及癌旁组织中VEGF-D阳性率高于无淋巴结转移和Ⅰ、Ⅱ期患者(P<0.05或P<0.01)。癌旁MLVD高于正常组织及胃癌组织。癌旁组织中VEGF-D阳性的MLVD高于VEGF-D阴性者(P<0.01)。而胃癌组织中VEGF-D阳性的MLVD与VEGF-D阴性的MLVD差异无统计学意义(P>0.05)。结论:胃癌癌旁组织中VEGF-D及MLVD的检测可作为评估胃癌淋巴结转移、判断胃癌生物学行为及预后的指标之一。

Research of Relationship between Expression of VEGF-D and MLVD in Gastric Cancer

Objective: To detect the expression of vascular endothelial growth factor-D (VEGF-D) and micro-lymphatic vessel density (MLVD) in patients with gastric cancer, and their relationship thereof. Methods: Fifty-two samples of gastric cancer patients after surgery were collected. The immunohistochemistry method was used to determine expression levels of VEGF-D and MLVD in gastric cancer, borderline tumor and normal tissues. The relationship between expression levels of VEGF-D and MLVD, patient age, gender and cl...
