摘      要：Background: Members of the NFκB [p65] family have potential diagnostic and prognostic role in various inflammatory diseases and Lymphomas. Aim: We studied NFκB [p65] in paraffin blocks of hepatitis-C-virus [HCV] positive genotype-4 and HCV negative diffuse large B-cell lymphoma [DLBCL] patients, aiming at identification of its differential expression and prognosis in DLBCL and its subtypes;GCB and ABC. This is to establish its relation to HCV infection and its role in lymphogenesis. Besides assessing the role of new directly acting antiviral drugs [Sofusbuvir/Ledipasvir] concomitantly administered to [CHOP] combination in HCV positive DLBCL. Subjects and Methods: NFκB [p65] expression was assessed using Anti-NFκB [p65] antibody semi-quantitative technique in 30 newly diagnosed DLBCL patients [HCV positive [n = 15], HCV negative [n = 15]. Results: NFκB [p65] expression was higher in the HCV positive DLBCL patients than their HCV negative counterpart, with a positive correlation with the viral load [r = 0.536, p = 0.088]. NFκB [p65] expression was significantly more frequently detected in the ABC subtype than GCB subtype [p = 0.04]. Patients who expressed NFκB [p65] had higher incidence of extranodal involvement, advanced stages, higher LDH levels and IPI score. Besides, the expression of NFκB [P65] revealed an inferior overall response [OR] [p = 0.044]. Higher complete response rates to CHOP concomitantly with antiviral [ledipasvir/sofosbuvir] were encountered in the HCV positive group. In HCV positive group, NFκB [P65] displayed a positive relationship with the viral load and liver enzymes [p = 0.04], besides an inverse relation with serum albumin. This raises the possibility that NFκB [p65] expression is suggestive of the hepatic necro-inflammation in HCV patients. The ABC group presented more in advanced stages than GCB. Higher frequency of the ABC subgroup exhibited intermediate to high viral load, while it was less in the GCB. A statistically significant differe
