摘要
目的 :探讨p5 3基因单链构象多态性变化与食管鳞癌患者术后生存期的关系。方法 :采用聚合酶链反应 单链构象多态性 (PCR SSCP)结合银染技术 ,对 47例河南林县食管鳞癌患者癌组织及癌旁正常组织中p5 3基因第 5~ 8外显子进行比较。结果 :p5 3基因第 5~ 8外显子出现异常电泳条带者 2 0例 (4 2 6 % ) ;生存期大于 5a组与生存期小于 5a组 ,p5 3基因单链构象多态性变化发生率分别为 32 1% (9/ 2 8)和 5 7 9(11/ 19) ,2组比较 ,差异无显著性(χ2 =3 0 71,P >0 0 5 )。结论 :食管鳞癌组织p5 3基因第 5~
Aim: To investigate the relationship between the single strain conformation polymorphism alteration of p53 and the survival rate in the patients with esophageal squamous cell carcinoma Methods: PCR SSCP methods and silver staining technique were used to analyse the alteration of p53 gene in the exons 5~8 in 47 cases with esophageal squamous cell carcinoma Results: Abnormal shift bands in the exons 5~8 of the p53 gene were found in 20 cases out of 47 patients with esophageal squamous cell carcinoma,which accounted for 42 6%(20/47) The alterations of p53 gene were found more frequently in the patients with less than 5 years survival rate (57 9%,11/19) than those in the patients with longer than 5 years survival rate (32 1%,9/28). However,the difference was not significant ( P >0 05) Conclusion: The result suggests that p53 gene single strain conformation polymorphism alteration may not play an important role in the prognosis for the patients with esophageal squamous cell carcinoma
