ABSTRACT
Objective To investigate the clinical features, BCL-2,CMYC protein expression and prognosis of patients with hepatitis B virus-associated diffuse large B-cell lymphoma (DLBCL).Methods A retrospective study was used to analyse 94 diagnosed DLBCL patients clinical data.Immunohistochemistry method was used to detect the expression of BCL-2 and CMYC protein in paraffin sections of tumor tissues, and to analyze the clinical features, protein expression and prognosis of patients with hepatitis B virus-associated DLBCL.Results ① The rate of HBV infection in the 94 DLBCL patients was 27.66%, significantly higher than the general population(7.18%).Compared with HbsAg-negative DLBCL, HbsAg-positive DLBCL displayed more advanced disease(P=0.032), higher international prognostic index (IPI)(P=0.047) and more frequent involvement of spleen(P=0.02).There were no significant differences in gender distribution, age, immunological subtype and treatment between the two groups.② The aspect of BCL-2 and CMYC protein expression between the two groups HbsAg-positive group BCL-2 protein expression was significantly higher than HbsAg-negative group (84.6% vs 58.8%, P=0.018).There were no significant differences on the CMYC protein expression and CMYC/ BCL-2 double expression.③ Univariate survival analysis showed that hepatitis B virus infection, BCL-2 positive, CMYC positive, CMYC/ BCL-2 double expression, IPI high-risk group were associated with unfavorable prognostic of overall survival time (OS) and progression free survival (PFS).Cox multivariate analysis showed that CMYC/BCL-2 double expression, IPI high-risk group were independent adverse prognostic factors for OS and PFS.Conclusion HBV infection, BCL-2, CMYC, BCL-2/CMYC double expression, IPI are related to the prognosis of DLBCL.HBV infection may affect the development and prognosis of DLBCL by regulating the expression of BCL-2.
