The advances in low-grade lymphoma & T-cell lymphoma from the 2008 ASH meeting were presented. These included therapeutic regimens for low grade lymphoma, frontline bendamustine plus rituximab data, radioimmunotherapy consolidation in advanced disease, idiotype vaccine, and other novel therapeutic agents such as next generation anti-CD20 GA101, syk inhibitor Fostamatinib in treatment of low-gra...

Extranodal natural killer (NK)/T-cell lymphoma, nasal type (ENKTCL-NT) is an uncommon subtype of nonHodgkin lymphoma with an aggressive course and poor prognosis, which is mainly seen in Asia and Latin America. ENKTCL is associated with the Epstein-Barr virus (EBV) and is characterized by vascular destruction and prominent necrosis. We reported a 53-year-old Chinese man who was diagnosed with E...

In Japan, EBV positive rate in immunocompetent patients with nodal lymphomas is less than 10% in B-cell and 20-50% in T cell lymphoma. Among extranodal lymphomas, EBV positive rate is higher in pyothorax-associated lymphoma (PAL), nasal NK/T-cell lymphoma, and adrenal lymphoma. PAL is non-Hodgkin's lymphoma that develops from chronic pyothorax resulted from artificial pneumothorax for the treat...

A 74-year-old woman developed bilateral uveitis with high Epstein-Barr virus (EBV) DNA load in the vitreous fluid without lymphoma cells. Four years after the onset, T2-weighted contrast-enhanced MRI revealed hyperintense lesions in the right occipital and parietal lobe. A biopsy resulted in the diagnosis of extranodal NK/T-cell lymphoma nasal type (ENKL). The repeat region of LMP1, an EBV gene...

BACKGROUND A growing number of studies demonstrate the utility of (18)fluoro-2-deoxyglucose positron emission tomography (FDG-PET) in the management of malignant lymphoma. The results of FDG-PET, however, have not been studied extensively for T-cell and natural killer (NK)-cell neoplasms. PATIENTS AND METHODS We retrospectively evaluated pretreatment FDG-PET scans in 41 patients with T/NK-cel...

Purpose: To identify tumor suppressor genes epigenetically silenced by promoter hypermethylation in extranodal natural killer cell lymphoma (NKCL). Experimental Design: Promoter methylation was analyzed with global and locus-specific methylation assays in NKCL cases and NK cell lines. Gene expression profiles were used to identify genes for which aberrant promoter methylation was associated wit...

The pathogenesis of Epstein-Barr virus-positive (EBV+) mature T-cell and natural killer (NK)-cell neoplasms is challenging to understand. The clinical features are diverse, with no typical manifestation. Therefore, it is important to analyze the association of the clinical characteristics and prognoses of patients with various factors associated with EBV+ T/NK-cell neoplasms, particularly extra...
