摘要
目的:研究胃癌中肿瘤相关巨噬细胞(tumor associated macrophages,TAMs)的表达及其与肿瘤血管生成的关系,进而分析其与转移的相关性。方法:利用免疫组化双染方法同时标记TAMs(抗CD68抗体)和内皮细胞(抗CD34抗体),检测90例胃癌中TAMs、微血管密度(microvessel density,MVD)。结果:①TAMs与胃癌的大小、淋巴结转移、远处转移呈显著正相关(P均<0.05);②MVD与胃癌的远处转移呈显著正相关(P均<0.05);③在胃癌组织中TAMs与MVD的表达呈显著的正相关(r=0.325,P=0.002)。结论:TAMs可能通过促进胃癌血管的生成,进而促进胃癌细胞发生血管内渗,最终实现胃癌细胞的转移。
Objective： To investigate the expression of tumor associated macrophages（TAMs） and their relationship between TAMs, tumor angiogenesis and metastasis in gastric cancer. Methods： The expression of TAMs and microvessel density（MVD） in 90 case of Paraffin-embedded gastric cancer samples were stained using double-immunostaining method allowing simultaneous identification of macrophages and endothelial cells. Results： ① TAMs density had a positive relationship with the tumor size, lymph node metastasis,distant metastasis（P0.05）;②MVD had a positive correlation with distant metastasis（P 0.05）;③Positive correlation of TAMs and MVD was found in gastric carcinoma（r=0.325,P=0.002）. Conclusions： TAMs could assist tumor cell intravasation and metastasis through promoting angiogenesis in gastric cancer.
