112例套细胞淋巴瘤临床病理分析

Clinicopathologic features of 112 patients with mantle cell lymphoma

目的:探讨套细胞淋巴瘤(mantle cell lymphoma,MCL)的临床病理特点。方法:收集112例MCL的临床及病理资料,采用免疫组织化学(Envision二步法)行相关抗体标记,荧光原位杂交技术(fluorescence in situ hybridization,FISH)对其中24例作Ig H/CCND1基因断裂检测。结果:112例(包括2例多形性和母细胞变亚型)均表达B细胞相关抗原,94.6%(106/112)表达cy-clin D1,92.9%(104/112)表达CD5。不同免疫表型的经典型MCL的Ki-67及平均生存期无统计学差异(P>0.05)。3例CD5-的MCL未检测出Ig H/CCND1基因断裂,2例经典型MCL检测出Ig H/CCND1多倍体。结论:MCL是一种具有特殊免疫表型的B细胞淋巴瘤,多形性及母细胞变异型的预后较差,对特殊亚型的MCL诊断有必要细分。

Objective：To explore the clinicopathologic features of 112 patients with mantle cell lymphoma （MCL）. Methods：Da-ta from 112 MCL cases were collected, and immunohistochemical assay was conducted. A break in the CCND1 gene was detected by fluorescence in situ hybridization （FISH）. The t-test was used in the statistical analysis. Results：All tumor cells in the 112 cases ex-pressed B cell-related antigen, including 1 blastoid subtype and 1 polymorphic subtype. Among all the cases, 106 expressed CD5 and 104 expressed cyclinD1. A break in the CCND1 gene was not found in 3 cases with CD5-MCL. IgH/CCND1 polyploid was found in 2 classical cases. Conclusion：MCL is a type of special immunophenotypic B-cell lymphoma. The prognoses of blastoid and polymorphic subtypes are poor. Special subtypes should be classified during diagnosis.
