摘要 目的探讨p53和Ki-67的表达在人胸腺瘤发生、侵袭和转移中的临床意义及其相互关系。方法 采用免疫组化SP法检测50例胸腺瘤患者p53和Ki-67的表达。结果 在WHO分型A+AB型、B1+B2+B3型、C型胸腺瘤患者中,p53和Ki-67表达率逐渐增高,差异有统计学意义(χ2=6.525,8.452;P=0.038,0.015);在Masaoka分期I期、Ⅱ+Ⅲ+Ⅳ期胸腺瘤患者中,p53和Ki-67表达率逐渐增高,差异有统计学意义(χ2=5.556,4.757;P=0.018,0.029);p53和Ki-67的表达呈正相关(r=0.142;P=0.003)。结论 p53和Ki-67的过度表达在胸腺瘤发生、浸润和转移中起一定的作用;共同影响着胸腺瘤的发生、发展。两者的检测有助于对胸腺瘤的早期诊断,并判断其恶性程度、侵袭和转移能力及预后。
