HCV infection, B-cell non-Hodgkin's lymphoma and immunochemotherapy: Evidence and open questions

World Journal of Gastrointestinal Oncology 2012年第3期4卷 46-53页

作者： maria Christina Cox maria antonietta aloe-spiriti Elena Cavalieri Eleonora Alma Elia Gigante Paola Begini Caterina Rebecchini Gianfranco Delle Fave Massimo Marignani Department of Haematology Sant'Andrea Hospital La Sapienza University Department of Gastroenterology and Liver Disease Sant'Andrea Hospital La Sapienza University

There is plenty of data confirming that hepatitis C virus (HCV) infection is a predisposing factor for a B-cell non-Hodgkin's lymphoma (B-NHL) outbreak, while relatively few reports have addressed the role of HCV in affecting B-NHL patients' outcome. 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.

Dear Editor,The tumor suppressor gene CDKN1B,encoding for the p27^(Kip1)(p27)protein,defines the smallest region of deletion on chromosome 12p13 described in clonal hematopoietic disorders(CHDs)[1].Among them,myelodysplastic syndromes(MDSs)display typical onset in the elderly and an indolent behavior that may evolve in acute myeloid leukemia(AML)[2].Recent evidences support a model of parallel clonal evolution at the stem or progenitor cell level and implicate the need of more preclinical,translational and clinical research to identify better ways to timely target clones that may evolve toward malignancy[3,4].
