Hepatitis C virus (HCV) infection increases the risk of B-cell non-Hodgkin lymphomas (B-NHL). Antiviral treatment (AT) can induce hematological responses in patients with marginal zone lymphomas (MZL). The ANRS HC-13 Lympho-C study aimed at a better understanding of the impact of AT on HCV associated B-NHL. This multicentric study enrolled 116 HCV-positive patients with B-NHL between 2006 and 2012. Cytological and histological samples were collected for centralized review. At lymphoma diagnosis, median age was 61 years and gender ratio M/F was 1. Cytohistological distribution was marginal zone lymphoma (MZL) n=45 (39%), diffuse large B-cell lymphoma (DLBCL) n=45 (39%), and other types n=26 (22%). MZL patients had more frequent detection of rheumatoid factor (68% vs. 35%; P=0.001) and more frequently mixed cryoglobulinemia (74% vs. 44%; P=0.021) than patients with DLBCL. Among patients receiving AT, a sustained virologic response was achieved in 23 of 38 (61%) patients with MZL and in 9 of 17 (53%) with DLBCL (P=0.42). Three-year overall survival (OS) and progression-free survival were 78% 95%CI [63-88] and 64% [48-76], respectively, without difference between cytohistological groups. Outcome analysis showed a favorable association between OS and AT in all patients (P=0.05) and in the subgroup of MZL patients only (P=0.04). Our data support that AT improves the outcomes of HCV-associated NHLs. The impact of new AT regimen with protease inhibitor needs to be investigated in this setting.
