Expression of NF-κB in B cell lymphoma carcinoma and its clinical significance

  • Online:2015-12-25 Published:2016-01-11

摘要:

目的 探讨核转录因子-κB(nuclear factor κB,NF-κB)在B细胞淋巴瘤组织中的表达及其与临床病理特征的关系。方法 采用免疫组化法检测42例B细胞淋巴瘤组织(B细胞淋巴瘤组)及20例淋巴结反应性增生组织(对照组)中NF-κB蛋白的表达。分析NF-κB表达与B细胞淋巴瘤临床病理特征的关系。结果 NF-κB在B细胞淋巴瘤组织和淋巴结反应性增生组织中的阳性表达率分别为78.57%(33/42)和20%(4/20),两组比较差异有统计学意义(P<0.001)。NF-κB的表达与恶性程度、临床分期有关(P<0.05);而与年龄、性别、乳酸脱氢酶(LDH)水平无关(P>0.05)。结论 NF-κB在B细胞淋巴瘤发生、发展中起重要作用,有望成为判断淋巴瘤患者预后的指标。

Abstract:

Objective To investigate the expression of nuclear transcription factor κB(NF-κB)in B cell lymphoma,and analyze possible relationships between expression and clinicopathological characteristics. Methods Immunohistochemistry was used to detect NF-κB protein expression in tissues from 42 patients with B cell lymphoma and 20 patients with reactive lymph node hyperplasia. Relationships between NF-κB expression and clinicopathological characteristics were analyzed. Results The rate of NF-κB-positive tissue was significantly higher among patients with B cell lymphoma (78.57%,33/42) than among those with reactive lymph node hyperplasia(20%,4/20;P<0.001). Level of NF-κB protein expression correlated with Ann-Arbor clinical stage and histology grade (P<0.05),but not with sex,age or lactate dehydrogenase (LDH)level (P>0.05). Conclusion NF-κB plays an important role in the development of B cell lymphoma, and it may serve as a prognostic indicator.
