370例恶性淋巴瘤的WHO(1997)分类

目的：研究恶性淋巴瘤的临床、病理特点。方法：根据WHO(1997)分类标准对370例恶性淋巴瘤患进行临床、病理及免疫表型分析。结果：非霍奇金淋巴瘤(NHL)359例，占97．03％；霍奇金淋巴瘤(HL)11例，占2．97％。NHL中，B细胞淋巴瘤246例，占68．52％；T细胞淋巴瘤108例，占30．08％；组织细胞性淋巴瘤和滤泡树突状细胞肉瘤各1例，NK细胞性淋巴瘤3例。结外淋巴瘤(196例，占54．6％)多于结内淋巴瘤(163例，占45．4％)。NHL中发病率较高的淋巴瘤类型依次为：弥漫大B细胞淋巴瘤(173例，占48．2％)，外周非特殊T细胞淋巴瘤(54例，占15．0％)，黏膜相关淋巴组织细胞淋巴瘤(31例，占8．6％)，NK／T细胞淋巴瘤(25例，占7.0％)，滤泡性淋巴瘤(21例，占5．8％)，间变性T细胞淋巴瘤(12例，占3．3％)。结论：应用WHO(1997)分类对恶性淋巴瘤进行分析研究，具有重要的临床意义。

The WHO (1997) classification of 370 cases of malignant lymphomas

OBJECTIVE: To reclassify retrospectively 370 cases of malignant lymphomas. METHODS: According to the WHO new classification, the clinical features and pathology as well as immunophenotype of 370 lymphomas were analysed. RESULTS: In 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%). CONCLUSION: The results suggested that the study of malignant lymphomas with WHO new classification have important clinical significance.
