HCV infection may influence the short-term outcome of B-NHL because of the emergence of severe hepatic toxicity (HT) during immunochemotherapy. Furthermore, the long term outcome of HCV-related liver disease and patients' quality of life will possibly be affected by Rituximab maintenance, multiple-lines of toxicity during chemotherapy and hematopoietic stem cell transplantation. In this review, data dealing with aggressive and low-grade B-NHL were separately analyzed. The few retrospective papers reporting on aggressive B-NHL patients showed that HCV infection is a risk factor for the outbreak of severe HT during treatment. This adverse event not infrequently leads to the reduction of treatment density and intensity. Existing papers report that low-grade B-NHL patients with HCV infection may have a more widespread disease, more frequent relapses or a lower ORR compared to HCV-negative patients. Notwithstanding, there is no statistical evidence that the prognosis of HCV-positive patients is inferior to that of HCV-negative subjects. HCV-positive prospective studies and longer follow-up are necessary to ascertain if HCV-positive B-NHL patients have inferior outcomes and if there are long term sequels of immunochemotherapies on the progression of liver disease.展开更多
