摘要(Abstract):

目的:检查CD5在淋巴结内弥漫大B细胞淋巴瘤(DLBCL)中的表达情况,了解CD5表达与肿瘤细胞中CD10、bcl-6、MUM1表达的关系,以及上述分子标记对肿瘤的临床病理特征和预后的影响。方法:HE染色观察淋巴结内DLBCL的组织学特征,免疫组织化学染色检测CD5、CD10、bcl-6、MUM1和Ki-67表达。结果:39例DLBCL中25例表达CD5,DLBCL的CD5阳性和阴性组的CD10,bcl-6,MUM1、Ki-67的表达、年龄、性别、体能指数及生存状况无显著性差异,但两组的临床分期有显著性差异。CD10(-)bcl-6(-)MUM1阳性组与阴性组之间生存状况无显著性差异,CD10和(或)bcl-6表达组与MUM1表达组及Ki67表达>20%与≤20%病例之间生存状况无明显差异。结论:DLBCL中CD5表达与CD10、bcl-6、MUM1的表达无明显相关,但与肿瘤的临床分期有关,CD5阴性病例的分期较低;CD5表达对DLBCL的其它临床特征和生存状况无明显影响,CD10、bcl-6、MUM1表达对DLBCL的生存状况有一定影响。
Objective:To detect the expression of CD5 in nodal diffuse large B cell lymphoma (DLBCL) and understand the correlation between CD5 expression and the expression of CD10,bcl-6,and MUM1 in DLBCL as well as its effect on the clinicopathological features and prognosis of DLBCL. Methods: Pathological specimens of 39 cases of DLBCL were collected and their histopatholigical features were observed with HE stained sections. Some immunophenotypes of DLBCL ( CD5,CD10,bcl-6,and MUM1,etc.) and Ki-67 expression were detected by using immunohistochemistry staining. Result: Expression of CD5 was detected in 25 DLBCL cases out of 39. There was no statistical difference of expression of CD10,bcl-6,MUM1,or Ki-67 between CD5-postive (CD5+) and -negative (CD5-) groups,neither the survival status or clinicopathological features such as age,sex and so on were statistically different between the 2 groups. While there were indeed statistical differences of staging between the two groups. The differences of survival status between CD10-,bcl-6-,and MUM1-postive and -negative groups were not significant. There was no obvious difference of survival between CD10/ bcl-6-postive and MUM1-postive groups,or between Ki-67≥20% and <20% groups. Conclusions: The expression of CD5 is not related to the expression of CD10,bcl-6,MUM1 in DLBCL,but is related to the staging of DLBCL. The stages are lower in CD5-negative cases than those in CD5-postive cases. CD5 expression is not associated with other clinical features or survival status of DLBCL. The expressions of CD10,bcl-6,MUM1 affect the prognosis of DLBCL.
