摘要 目的探讨流式细胞术(flow cytometry,FCM)结合PCR检测Ig基因重排在B细胞淋巴瘤(B-celllymphoma,B-NHL)细针穿刺小标本诊断中的应用价值。方法对经组织学确诊的36例B-NHL和28例反应性增生的浅表淋巴结肿大病例行细针穿刺,对其组织学形态、免疫组化染色、FCM免疫表型及细胞学形态进行回顾性分析,并采用BIOMED-2系统引物分析Ig基因重排情况,总结B-NHL各亚型的FCM免疫表型特点及细胞学特点,以及对比分析FCM与Ig基因重排联合诊断与组织学诊断之间的符合率。结果 36例组织学诊断的B-NHL中,31例经FCM/Ig基因重排可确诊(符合率为86.1%),23例可以区分亚型(符合率为63.9%)。28例组织学诊断的反应性增生中,27例经FCM/Ig基因重排可确诊(符合率为96.4%)。结论 FCM免疫表型联合Ig基因重排在对B-NHL诊断和分型方面有较高的应用价值,尤其适用于细针穿刺小标本,但对富于T细胞性大B-NHL和淋巴瘤结内非弥漫性病变的病例诊断意义不大。
