Case Reports
[Five adult cases of Epstein-Barr virus-associated hemophagocytic lymphohistiocytosis].
Epstein-Barr virus-associated hemophagocytic lymphohistiocytosis (EBV-HLH) is more common in children, and is characterized by pancytopenia, liver dysfunction and coagulopathy caused by interactions between EBV-infected T cells and activated macrophages. We describe here five adults with EBV-HLH. The median age was 17 years (range 16 approximately 40). ⋯ All patients received immunosuppressive therapy with or without etoposide, and two patients required plasmapheresis due to the severity. Three patients are alive in complete remission (follow up periods; 13, 19, 30 months), while two patients became refractory to chemo-immunotherapy and died despite multidrug chemotherapy. EBV-HLH should be more widely recognized in adults in order to achieve early diagnosis and appropriate treatment.

Clinical Trial
[Clinical study of sequential high-dose chemotherapy with in vivo rituximab-purged stem cell autografting for mantle cell lymphoma].
Sequential high-dose chemotherapy with in vivo rituximab-purged stem cell autografting was designed for previously untreated mantle cell lymphoma (MCL). The response rate, disease-free survival (DFS), overall survival (OS) and toxicity were investigated in this trial. Between November 2001 and August 2008, five patients younger than 65 years of age with MCL at diagnosis were enrolled in this study. ⋯ One patient relapsed 3.2 years after treatment. The principal toxicity in the study was hematologic but there were no treatment-related deaths. Intensive high-dose sequential chemotherapy with in vivo purged stem cell support can achieve long-term disease-free survival for MCL.
