摘要
目的:探讨p53基因在骨肉瘤组织中的表达及其临床意义。方法:应用免疫组化方法(S-P法)测定p53蛋白在36例骨肉瘤和17例骨软骨瘤组织中的表达,并随访骨肉瘤患者生存时间。36例骨肉瘤中男19例,女17例,年龄平均19.9岁。Ennek ing分期Ⅱa3例,Ⅱb27例,Ⅲb6例,并发病理性骨折7例。结果:36例骨肉瘤随访时间平均3年6个月,其中存活3年及以上者13例,存活3年以下者23例,死亡病例均因骨肉瘤远处转移全身衰竭致死。36例骨肉瘤p53蛋白阳性表达率为52.8%,显著高于骨软骨瘤组,有显著性差异(P<0.01)。p53蛋白表达在不同Ennek ing外科分期组间无显著性差异(P>0.05),在生存时间3年以上组及3年以下组间有显著性差异(P<0.01)。结论:p53基因突变对骨肉瘤的发病可能产生影响,对患者预后评估具有一定价值。
Objective:To explore the protein expression of P53 in osteosarcoma and its relationship with clinical features and prognosis. Methods: The protein expression of P53 was detected by using immunohistochemistry (LSAB) in 36 cases of osteosarcoma and 17 cases of osteochondroma, proved by surgery and pathology, and the sur- vival time in 36 cases of osteosarcoma were followed - up. Results : All 36 cases of osteosarcoma were followed - up with the average time of 42 months ,there were 13 cases survival more than 36 months, the positive expression rate of p53 was 52.8% in 36 cases of osteosarcoma, and higher than in osteochondroma , (P 〈0.01 ). the positive expres- sion rate of p53 was higher in 23 cases survival less than 36 months. Conclusion:Threr is a definite relationship between p53 and osteosarcoma, p53 is useful for the assessment of the prognosis of osteosareoma.
