Abstract： 目的研究卵巢上皮性癌组织中肿瘤浸润性树突状细胞(TIDC)的状态及其与血管内皮生长因子(VEGF)表达的关系.方法采用免疫组化链霉菌抗生物素蛋白-过氧化酶连接法和Picture二步法,检测57例卵巢上皮性癌(恶性组)、30例良性卵巢上皮性肿瘤(良性组)及16例正常卵巢 (正常组) 组织中S-100蛋白、CD83标记的TIDC状态及其VEGF的表达.结果 (1)恶性组TIDC光镜下形态基本可分成两种,其分布有异质性.恶性组S-100+ TIDC中位数为4.3个/400高倍视野(HPF),分别与良性组(中位数为1.8个/HPF)和正常组(中位数为2.0个/HPF)比较,差异有显著性(P值分别为0.000和0.015).恶性组中,早期(Ⅰ～Ⅱ期)肿瘤组织中S-100+ TIDC数量明显多于晚期(Ⅲ～Ⅳ期,中位数分别为6.0个和3.8个/HPF,P=0.026).恶性组中, CD+83 TIDC浸润肿瘤间质者极少,中位数为0个/HPF.(2)恶性组细胞中VEGF高表达(5.0分),分别与良性组(3.8分)和正常组(2.4分)比较,差异均有极显著性(P=0.000).(3)恶性组中,S-100+ TIDC数量与VEGF表达呈明显负相关(P=0.001).结论 (1)卵巢上皮性癌细胞可刺激TIDC的募集,但同时受VEGF的抑制.(2)卵巢上皮性癌中TIDC成熟严重受抑.
