Unfavorable prognosis of elderly patients with early-stage extranodal nasal-type NK/T-cell lymphoma.
BACKGROUND Extranodal nasal-type NK (natural killer)/T-cell lymphoma in elderly patients is rare, and its prognosis is unclear. This study aims to investigate the clinical characteristics and prognosis of this lymphoma. PATIENTS AND METHODS We analyzed 24 patients (age, >60 years old) with early-stage extranodal nasal-type NK/T-cell lymphoma. Among these patients, 23 received radiotherapy alo...
Extranodal natural killer/T cell (NK/T cell) lymphoma (ENKTL), nasal type, is a rare non-Hodgkin lymphoma originating in the nasal cavity or in the paranasal sinuses. It can involve the skin, gastrointestinal tract, soft tissue, and testis, but involvement of breast is rare. Herein we report a case of extranodal NK/T cell lymphoma with bilateral breast involvement in a middle aged female. The u...
Natural killer (NK) cell neoplasms, which include extranodal NK/T-cell lymphoma (nasal and extranasal) and aggressive NK cell leukemia, are generally rare, but they are more common in people of Oriental, Mexican and South American descent. These neoplasms are highly aggressive, and show a strong association with Epstein-Barr virus. Extranodal NK/T-cell lymphoma most commonly affects the nasal c...
INTRODUCTION Non-Hodgkin's lymphomas (NHL) in China appear to have many characteristics different from those Western countries, but clinical studies to provide details have been rare so far. METHODS This study retrospectively analyzed the characteristics of clinical and pathological data for the 1248 NHL patients in the Shandong region of China between 2002 and 2010. RESULTS From 2002 to 20...
Natural Killer(NK) cell nenoplasm is heterogeneous disease group. In the latest World Health Organization(WHO) classification of tumors of hematopoietic and lymphoid tissue(2008), disease entities considered as NK cell deviation are 1) Aggressive NK cell leukemia (ANKL), 2) NK cell lymphoblastic leukemia/lymphoma, 3) Extranodal NK/T-cell lymphoma, nasal. While several NK related diseases are pr...
The World Health Organization (WHO) classification recognizes 2 main categories of natural killer (NK) cell-derived neoplasms, namely, extranodal NK/T-cell lymphoma, nasal type, and aggressive NK-cell leukaemia. Extranodal nasal NK/T-cell lymphoma is more frequent in the Far East and Latin America. Histopathological and immunophenotypical hallmarks include angiocentricity, angiodestruction, exp...
Purpose: We investigated prognostic implications of microRNAs in extranodal NK/T cell lymphoma
To estimate the distribution of lymphoid neoplasms in China, we conducted a comprehensive analysis, based on subtype, age, sex, and lesion, of primary and resected biopsy specimens of 4,638 lymphoid neoplasms diagnosed from 2004 to 2008 at 5 large hospitals. Of the 4,638 patients, mature B-cell neoplasms accounted for 64.3% of all lymphoid neoplasms, mature T/NK-cell neoplasms for 23.3%, and Ho...
