4、瘤的复发率为 6.25%(1/16),恶性叶状肿瘤的复发率为 12.50%(1/8)。Pearson 相关性分析结果显示:叶状肿瘤中 Ki67 的表达与复发率呈正相关(r=0.871,P=0.032),CD34、BCL2 的表达与复发率均呈负相关(r=-1.000,P0.001;r=-1.000,P0.001),CD117 的表达与复发率不相关(r=0.723,P=0.482)。结论CD34、CD117、BCL2、Ki67 免疫组化联合应用在乳腺叶状肿瘤诊断及预后判断中具有一定的价值,尤其对于微创手术标本或穿刺标本,可以指导临床诊治。关键词 乳腺叶状肿瘤;免疫组化;CD34;CD117;BCL
