新疆地区645例淋巴组织肿瘤的构成分析

Constitution of lymphoid neoplasm in Xinjiang: analysis of 645 cases

目的探讨新疆645例淋巴瘤的病理类型和亚型分布特点。方法收集2008年4月~2013年3月新疆自治区人民医院存档的645例淋巴瘤,复习HE、免疫组化切片及临床相关资料,按WHO（2008）造血和淋巴组织肿瘤分类标准进行诊断、分类。结果 645例淋巴瘤中,非霍奇金淋巴瘤（non-Hodgkin’s lymphoma,NHL）558例（86.51%）,霍奇金淋巴瘤（Hodgkin’s lymphoma,HL）82例（12.71%）。NHL中B细胞淋巴瘤448例（80.29%）,T/NK细胞淋巴瘤110例（19.71%）。B细胞淋巴瘤中最常见的类型是弥漫性大B细胞淋巴瘤（258例,占所有病例40%）。T/NK细胞淋巴瘤以结外NK细胞淋巴瘤多见（41例,占所有病例6.36%）。伯基特淋巴瘤、淋巴母细胞性淋巴瘤均以维吾尔族多见,套细胞淋巴瘤、滤泡性淋巴瘤和结外黏膜相关组织边缘区淋巴瘤以汉族多见。HL最常见的亚型是混合细胞型、结节硬化型、富于淋巴细胞型。HL在不同民族中亚型分布有一定差异,发病年龄未见双峰,其中儿童所占比例最高。结论新疆不同民族淋巴瘤亚型分布存在一定差异,具有独特的民族特征。

Purpose To study the pathologic types and subtypes distribution of 645 cases of lymphoma in Xinjiang. Methods Clinical data of lymphoma from April 2008 to march 2013 in the people＇s hospital of Xinjiang Uygur autonomous region in Xinjiang were collected and reviewed,including morphological,immunohistochemical and clinical characteristics. According to the WHO classification all the cases were reappraised. Results Of the 645 cases,558 cases（ 86. 51%） were non-Hodgkin＇s lymphoma（ NHL） and 82 cases（ 12. 71%） were Hodgkin＇s lymphoma（ HL）. Among NHL cases,448 cases（ 80. 29%） were B-cell neoplasms and 110 cases（ 19.71%） were T/NK-cell neoplasms. The commonest subtype was diffuse large B-cell lymphoma（ 258 cases,comprising 40% of all lymphomas） and extranodal NK /T-cell lymphoma（ 41 cases,comprising 6. 36% of all lymphomas） in B cell lymphoma and T /NK cell lymphoma. Burkitt＇s lymphoma and lymphoblastic leukemia /lymphoma were predominanly Uyghurs,but mantle cell lymphoma,follicular lymphoma and extranodal marginal zone lymphoma of mucosa associated lymphoid tissue were predominanly Hans. The most common subtypes of Hodgkin＇s lymphoma are mixed cellularity,nodular sclerosis and lymphocyte-rich classical Hodgkin＇s lymphoma. Subtypes distribution of Hodgkin＇s lymphoma has a certain difference in the different ethnic groups,the age of onset did not present twin peaks and the highest proportion was children. Conclusion The lymphoid neoplasms of Xinjiang displayed some ethnic features similar to those reported in literature as well as other regions of China,whereas the distribution of some subtypes showed some differences.
