摘要 目的研究蛋白酶激活受体-1(PAR-1)在骨肉瘤中的表达情况及其与微血管密度(MVD)的相关性,探讨其在骨肉瘤侵袭转移中的作用。方法采用免疫组化法检测38例骨肉瘤及其癌旁组织中PAR-1的表达情况,以CD34为标记,计算MVD。结果 PAR-1阳性表达率及MVD在骨肉瘤组织中分别为89.4%、(42.5±12.8)条,显著高于癌旁组织中的55.3%、(14.8±6.5)条,且二者跟骨肉瘤的Enneking分期、软组织浸润、肺转移有关(P均<0.05)。PAR-1与MVD呈正相关(r=0.748,P<0.01)。结论 PAR-1在骨肉瘤肿瘤组织中存在过度表达,且与肿瘤微血管密度呈正相关,与肿瘤侵袭转移、血管生成相关。
