Abstract
Objective To assay the expression of MYC and BCL-2 proteins in diffuse large B-cell lymphoma (DLBCL),and to investigate the clinicopathological significances of MYC/BCL-2 co-expression in DLBCL.Methods Archived 76 DLBCL,NOS were collected and analyzed retrospectively.The clinicopathological characteristics,including Ann Arbor staging,the international prognostic index (IPI) score,Hans's classification and therapeutic effects,were re-evaluated.The co-expression of MYC/BCL-2 was detected by immunohistochemical staining using EnVision detection system.Results MYC or BCL-2 expression could be detected in 55 cases (72.4%) and 41 cases (53.9%),respectively.The co-expression of MYC/BCL-2 was observed in 33 cases (43.4%).There was a close relationship found between co-expression of MYC/BCL-2 and higher Ann Arbor staging (P=0.011),or worse therapeutic effect of patient (P=0.002).However,co-expression of MYC/BCL-2 was not correlated to other clinicopathological features,such as tumor site and Hans's classification.In addition,there was no correlation found among IPI score and all of clinicopathological features of DLBCL in this study.Conclusions Co-expression of MYC/BCL-2 in tumor cells might be a specific immunohistochemical phenotype of DLBCL,and combined with standard IPI score,which might be a valuable prognostic factor for DLBCL patients with rituximab treatment.关键词
