Abstract:
OBJECTIVETo reclassify retrospectively 370 cases of malignant lymphomas.
METHODSAccording to the WHO new classification, the clinical features and pathology as well as immunophenotype of 370 lymphomas were analysed.
RESULTSIn the 370 lymphomas, there were 359 non-Hodgkin's lymphomas (NHL) (97.03%) and 11 Hodgkin's lymphomas (HL) (2.97%). Of the 359 NHL, 246 were B-cell lymphomas (68.52%), 108 T-cell lymphomas (30.08%), 1 each histiocytic lymphoma and follicular dendritic cell sarcoma, and 3 NK cell lymphomas. The extranodal lymphomas were 196 cases (54.6%) and the nodal lymphomas 163 cases (45.4%). The incidence of NHL categories were in proper order as follows: diffuse large B cell lymphoma (173 cases, 48.2%) > peripheral T cell lymphoma (54 cases, 15.0%) > mucosa associated lymphoid tissue (MALT) lymphoma (31 cases, 8.6%) > NK/T cell lymphoma (25 cases, 7.0%) > follicular lymphoma (21 cases, 5.8%) > anaplastic large cell lymphoma (12 cases, 3.3%).
CONCLUSIONThe results suggested that the study of malignant lymphomas with WHO new classification have important clinical significance.
