摘  要:目的:应用组织芯片技术研究间变性大细胞淋巴瘤(ALCL)中ALK蛋白的表达及其与患者年龄和预后的关系。方法:建立包含30例ALCL及2例对照组织共96点阵的组织芯片,采用免疫组织化学SP法检测ALK蛋白表达,并应用SPSS软件进行统计学分析。结果:(1)ALK蛋自在2例皮肤原发ALCL均为阴性,28例系统性ALCL中有20例(71.4%)阳性,主要为细胞浆和/或细胞核棕黄色。(2)ALK蛋白阳性组的年龄低于ALK蛋白阴性组的年龄,两者差异具有显著性(P<0.05)。(3)ALK蛋白阳性组的预后好于ALK蛋白阴性组的预后,两者差异具有显著性(P<0.05)。结论:ALK蛋白的表达在ALCL中有很高的发生率,尤其是低年龄组的患者,它可以成为ALCL的诊断、鉴别诊断和判断预后的一个独立重要指标。ObJective: To investigate the relation of the anaplestic lymphoma kinase (ALK) protein、 age and prognostic in anaplastic large cell lymphoma by tissue microarray technique. Method: 30 cases of anaplastic large cell lymphoma and 2 cases d normal control tissues were examined using tissue microarray technique by immunohistochemistty, together with analysis by statistics. Resalts: (1) ALK protein expressed negative in 2 samples of primarily ALCL, but 9 out of 19 systematic ALCL expressed ALK protein in cytoplasm and/or nucleus (71.4%) . (2) CLinicaLly, the patients with ALK expression were younger than those without ALK expression (P〈0.05) . (3) The prognosis with ALK expression was better than those without p80 expression (P 〈0.05) . Conclusion: There was a high incidence rate of ALK expression in ALCL, especially in younger group. ALK expression might be an useful and independent marker for the differential diagnosis and prognosis estimation of ALCL.
