A revisit of prophylactic lamivudine for chemotherapy-associated hepatitis B reactivation in non-Hodgkin's lymphoma: a randomized trial.

Unlabelled: Lamivudine is effective to control hepatitis B virus (HBV) reactivation in HBV-carrying cancer patients who undergo chemotherapy, but the optimal treatment protocol remains undetermined. In this study, HBV carriers with newly diagnosed non-Hodgkin's lymphoma (NHL) who underwent chemotherapy were randomized to either prophylactic (P) or therapeutic (T) lamivudine treatment groups. Group P patients started lamivudine from day 1 of the first course of chemotherapy and continued treatment until 2 months after completion of chemotherapy.

Occult subcutaneous panniculitis-like T-cell lymphoma with initial presentations of cellulitis-like skin lesion and fulminant hemophagocytosis.

Hemophagocytic syndrome (HPS) may be primary or secondary to malignancies, infections, autoimmune diseases, or drugs. In most cases, HPS occurs at the same time as the diagnosis of underlying malignancy or when it relapses. In rare situations, the neoplastic disease can be occult, even for more than a decade.

Lactate dehydrogenase, not vascular endothelial growth factor or basic fibroblast growth factor, positively correlates to bone marrow vascularity in acute myeloid leukemia.

Background: Angiogenesis has been extensively studied in acute myeloid leukemia (AML). Lactate dehydrogenase (LDH), a common biochemical marker for tumor burden and anaerobic glycolysis, is a poor prognostic factor for AML. Regulated by hypoxia-induced factor, both vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) are responsive to cancer-related angiogenesis.

Rapidly fatal Langerhans' cell histiocytosis in an adult.

Langerhans' cell histiocytosis (LCH) is a disorder of unknown etiology, characterized by abnormal proliferation of cells of the dendritic cell lineage. The acute disseminated form of the disease characteristically occurs in children younger than 3 years of age. More indolent forms of LCH occur primarily in older children and young adults.
