RESUMO
Hepatitis C virus (HCV) infection is associated with lymphoproliferative disorders and B-cell non-Hodgkin lymphomas (B-NHLs). Evaluation of the efficacy and safety profiles of different antiviral therapies in HCV patients with B-NHL is warranted. METHODS: First, we evaluated the sustained virologic response (SVR) and safety of Peg-interferon-alpha (Peg-IFN) + ribavirin +/- first protease inhibitors (PI1s) therapy in 61 HCV patients with B-NHL enrolled in a nationwide observational survey compared with 94 matched HCV-infected controls without B-NHL. In a second series, interferon-free regimens using a newly optimal combination therapy with direct-acting antiviral drugs (DAAs) were evaluated in 10 patients with HCV and B-NHL. RESULTS: The main lymphoma type was diffuse large B-cell lymphoma (38%) followed by marginal zone lymphoma (31%). In the multivariate analysis, patients with B-NHL treated by Peg-IFN-based therapy exhibited a greater SVR rate compared with controls, 50.8% vs 30.8%, respectively, p<0.01, odds ratio (OR) = 11.2 [2.3, 52.8]. B-NHL response was better (p = 0.02) in patients with SVR (69%) than in patients without SVR (31%). Premature discontinuation of Peg-IFN-based therapy was significantly more frequent in the B-NHL group (19.6%) compared with the control group (6.3%), p<0.02. Overall, survival was significantly enhanced in the controls than in the B-NHL group (hazard ratio = 34.4 [3.9, 304.2], p< 0.01). Using DAAs, SVR was achieved in 9/10 patients (90%). DAAs were both well tolerated and markedly efficient. CONCLUSIONS: The virologic response of HCV-associated B-NHL is high. Our study provides a comprehensive evaluation of different strategies for the antiviral treatment of B-NHL associated with HCV infection.

INTRODUCTION: Over the past 3 decades, the appropriate management of metastatic germ cell tumours (GCT) has been defined by several phase III trials. Many follow-up recommendations have been published based on expert consensus. However, common clinical scenarios can still be vexing for clinicians who are less experienced at managing patients with testicular cancer. CASE REPORT: We highlight the arduous diagnostic work-up of a suspected late relapsing metastatic GCT in a patient suffering from fatigue, weight loss and prominent retroperitoneal lymph nodes, 4 years after first-line chemotherapy for metastatic seminoma. The various explorations finally led to the diagnosis of Whipple's disease. CONCLUSION: This unusual clinical case strongly highlights the need to perform an exhaustive evaluation, with a biopsy, if a late recurrent GCT is suspected to avoid pointless and potentially harmful treatment.
