目的:研究凋亡抑制蛋白 Survivin 与骨肉瘤分期、病理组织学的相关性。方法:我院67例骨肉瘤患者及同期21例良性骨软骨瘤,以免疫组织化学 SP 法检测凋亡抑制蛋白 Survivin 表达情况。分析骨肉瘤、良性骨软骨瘤 Survivin 阳性检出率,并对不同分期(Ennecking 外科分期)、组织学分型(WHO 骨肿瘤分类标准)及 Survivin 表达对3年生存率的预测价值。结果:67例骨肉瘤患者 Survivin 阳性者45例,阳性率67.16%,21例骨软骨瘤患者检出 1例,阳性率4.76%,比较差异有统计学意义(P <0.05)。Ⅰ-Ⅱa 期阳性检出率33.33%较Ⅱb -Ⅲ期的82.61%显著低下(P <0.05)。阳性率普通中心型>毛细血管扩张型>表面型,与表面型比较普通中心型及毛细血管扩张型阳性率均显著较高(P <0.05),普通中心型与毛细血管扩张型比较无统计学意义(P >0.05)。随访6个月,Survivin 阳性及阴性生存率分别为68.89%、90.91%,比较差异有统计学意义(P <0.05),12个月阳、阴性生存率分别为57.78%、77.27%(P >0.05),24个月阳、阴性生存率分别为42.22%、54.55%(P >0.05),36个月阳、阴性生存率分别为28.89%、45.45%(P >0.05)。结论:凋亡抑制蛋白 Survivin 与骨肉瘤分期、病理组织学有较强相关性,对骨肉瘤患者预后亦有一定预测价值,将其作为骨肉瘤新的治疗靶点及观察指标具有可行性。which was statistically significant (P <0.05).Ⅰ-Ⅱa stage positive rate (33.33%)was obviously lower than 82.61% of Ⅱb -Ⅲ stage(P <0.05).With the positive rate of general central type >telangiectasis >surface type, compared with surface type ,positive rates in general central type and telangiectasis were significantly higher (P <0.05),and the positive rates between the general central type and telangiectasis were no statistically significant(P >0.05).In 6 months of follow -up,the positive and negative survival rates of Survivin were 68.89% and 90.91% re-spectively,which difference was statistically significant(P <0.05).In 12 months,the positive and negative survival rates were 57.78% and 77.27% respectively(P >0.05).In 24 months,the positive and negative survival rates were 42.22% and 54.55% respectively(P >0.05).In 36 months,the positive and negative survival rates were 28.89%and 45.45% respectively(P >0.05).Conclusion:There is a certain extent predictive value of strong correlation be-tween inhibitor of apoptosis protein Survivin and osteosarcoma stage,histological,and also for prognosis of patients with osteosarcoma.
