摘要
Abstract
Purpose To investigate the expression of Che-mokine(C-X-C Motif)receptor 5(CXCR5)and its clinico-pathological significance in classic Hodgkin lymphoma(CHL).Methods The expression of CXCR5 was assessed in 33 pa-tients by immunohistochemistry(IHC),and retrospectively ana-lyzed the expression and clinical significance of CXCR5 in the four subtypes of CHL.Meanwhile,10 cases of ALK-positive an-aplastic large cell lymphoma(ALCL)and 10 cases of ALK-neg-ative ALCL were collected as the control group.ResultsThere were 31 cases with CXCR5-positive in all 33 cases(93.94％),including 15/16(93.75％)in nodular sclerosis CHL,12/13(92.31％)in mixed cellularity CHL,2/2 in lymphocyte-rich CHL,and 2/2 in lymphocyte-depleted CHL.The positive ex-pressions of CXCR5 in different immunophenotypes of CHL were as follow,31/33(93.94％)in CD30 positive and PAX5 weakly positive CHL.12/14(85.71％)in CD15 negative CHL,24/26(92.31％)in CD20 negative CHL,10/11(90.91％)in EBER-negative CHL and 5/6 in LMP1-negative CHL.CXCR5 were not expressed in all 20 cases of ALCL.Conclusion The positive expression rate of CXCR5 in CHL is high.When the tumor cells are negative for CD15,LMP1 and CD20 or EBER,CXCR5 also has a high positive expression rate,which is helpful for the diagnosis of CHL.CXCR5 can be used to differentiate CHL from ALCL,especially the cases lacking typical morpholo-gy and immunohistochemistry.关键词
