Distinguishing Burkitt lymphoma (BL) from B cell lymphoma, unclassifiable with features intermediate between diffuse large B-cell lymphoma (DLBCL) and BL (DLBCL/BL), and DLBCL is challenging. We propose an immunohistochemistry and fluorescent in situ hybridization (FISH) based scoring system that is employed in three phases - Phase 1 (morphology with CD10 and BCL2 immunostains), Phase 2 (CD38, CD44 and Ki-67 immunostains) and Phase 3 (FISH on paraffin sections for MYC, BCL2, BCL6 and immunoglobulin family genes). The system was evaluated on 252 aggressive B-cell lymphomas from Europe and from sub-Saharan Africa. Using the algorithm, we determined a specific diagnosis of BL or not-BL in 82%, 92% and 95% cases at Phases 1, 2 and 3, respectively. In 3·4% cases, the algorithm was not completely applicable due to technical reasons. Overall, this approach led to a specific diagnosis of BL in 122 cases and to a specific diagnosis of either DLBCL or DLBCL/BL in 94% of cases that were not diagnosed as BL. We also evaluated the scoring system on 27 cases of BL confirmed on gene expression/microRNA expression profiling. Phase 1 of our scoring system led to a diagnosis of BL in 100% of these cases.
区分伯基特淋巴瘤(BL)与具有弥漫性大B细胞淋巴瘤(DLBCL)和BL之间特征的无法分类的B细胞淋巴瘤(DLBCL/BL)以及DLBCL具有挑战性。我们提出了一种基于免疫组织化学和荧光原位杂交(FISH)的评分系统,该系统分三个阶段使用——第1阶段(结合CD10和BCL2免疫染色的形态学检查)、第2阶段(CD38、CD44和Ki-67免疫染色)和第3阶段(对石蜡切片进行MYC、BCL2、BCL6和免疫球蛋白家族基因的FISH检测)。该系统在来自欧洲和撒哈拉以南非洲的252例侵袭性B细胞淋巴瘤中进行了评估。使用该算法,我们在第1、2和3阶段分别对82%、92%和95%的病例确定了BL或非BL的明确诊断。在3.4%的病例中,由于技术原因该算法不完全适用。总体而言,这种方法在122例病例中明确诊断为BL,在未诊断为BL的病例中,94%明确诊断为DLBCL或DLBCL/BL。我们还在27例经基因表达/微小RNA表达谱确认的BL病例中评估了该评分系统。我们评分系统的第1阶段在这些病例中的100%都诊断为BL。
