Background: In Caucasian populations, the tumor cells of Epstein Barr virus (EBV)-positive classical Hodgkin Lymphomas (cHL) patients more frequently express HLA class I and HLA class II molecules compared to EBV-negative cHL patients. HLA expression (in relation to EBV) in Asian cHL patients has not been previously investigated. Methodology/Principal Findings: We randomly selected 145 cHL patients with formalin-fixed, paraffin embedded tissue blocks available from 5 hospitals from the Northern part of China. Hematoxylin & Eosin-stained slides were used to reclassify the histological subtypes according to the WHO classification....

Purpose In classical Hodgkin’s lymphoma (cHL), the impact of tumor cell Epstein-Barr virus (EBV) status on clinical outcome is controversial. Patients and Methods We assessed failure-free survival (FFS) and relative survival (RS) in 412 patients with cHL and age-defined subgroups in a population-based study in the northern Netherlands. Tumor cell EBV status was positive in 34%, and the median follow-up time was 7.1 years. Patients’ median age at diagnosis was 35 years (range, 7 to 91 years), and 63% had Ann Arbor stage I or II, 24% had...

MicroRNAs ( miRNAs) are an important class of small RNAs that regulate gene expression at the post-transcriptional level. It has become evident that miRNAs are involved in hematopoiesis, and that deregulation of miRNAs may give rise to hematopoietic malignancies. The aim of our study was to establish miRNA profiles of naive, germinal center ( GC) and memory B cells, and validate their expression patterns in normal lymphoid tissues. Quantitative (q) RT-PCR profiling revealed that several miRNAs were elevated in GC B cells, including miR-17-5p, miR-106a and miR-181b. One...
