- W580504992 abstract "目的探讨子宫内膜增生过长及子宫内膜样腺癌中血管内皮生长因子(VEGF)和血小板反应素1(TSP-1)表达与血管新生的关系以及对子宫内膜样腺癌的发生、发展中的作用.方法采用免疫组织化学方法分别检测子宫内膜正常(12例)、增生过长(13例)、不典型增生(18例)及子宫内膜样腺癌(50例)中微血管密度(MVD)、VEGF及TSP-1表达情况.结果子宫内膜不典型增生和内膜样腺癌中MVD明显大于内膜正常及增生过长者(P＜0.05),子宫内膜样腺癌IA期与不典型增生二者的MVD差异无显著性(P＞0.05),而与正常内膜和增生过长者差异有显著性(P＜0.05);VEGF表达与上述不同内膜病变中MVD呈正相关(r=0.843,P=0.000 1),而TSP-1表达仅在子宫内膜样腺癌中分别与MVD和VEGF呈负相关趋势(r=-0.233,P=0.1041;r=-0.235,P=0.100 3);在子宫内膜样腺癌中TSP-1间质高表达且具有异质性.结论子宫内膜不典型增生和子宫内膜样腺癌中VEGF对血管新生起正向调节作用;TSP-1在部分腺癌患者中表达增强,但其负向调节作用较弱,可能会使血管新生开关平衡失调,与子宫内膜样腺癌发生及发展有关." @default.
