摘要
目的探索聚合酶链反应(PCR)和地高辛系统检测 t(14;18)的特异性和敏感性。方法用该法检测了不同来源 DNA 标本中的 t(14;18)。结果 3株阳性对照细胞系、14例滤泡性非何杰金淋巴瘤(FNHL)中13例、4例弥漫性非何杰金淋巴瘤(DNHL)中2例的 DNA 内检出 bcl-2-JH 基因;阴性对照细胞系、正常人和其他肿瘤 DNA 中均未检出 t(14;18)。DNA 序列测定结果亦证实检出的阳性片段确实为 bcl-2-JH 基因。敏感性分析结果证实该法较单用 PCR 技术敏感1000~10000倍。结论 PCR 和地高辛系统确为敏感、特异、实用和对人体无害的检测 t(14;18)的方法。
