【摘要】 目的 探讨生发中心型(GCB)与非生发中心型(non-GCB)弥漫大B细胞淋巴瘤临床病理因素及其与预后关系。方法 98例经组织学和免疫组化确诊的弥漫大B细胞淋巴瘤患者, 按照Hans免疫分型, GCB型21例(A组), non-GCB型77例(B组), 比较两组生存率, 分析影响预后的相关因素。
结果 A组生存率高于B组(P<0.05);多因素分析显示, 两组乳酸脱氢酶(LDH)水平、国际预后指数(IPI)比较差异有统计学意义(P<0.05), LDH、IPI为弥漫大B细胞淋巴瘤的独立预后因素。结论 在弥漫大B细胞淋巴瘤中, non-GCB型更为常见, LDH、IPI评分是影响non-GCB型预后的主要因素, 应根据患者实际情况选择合适的治疗方案。

【Abstract】 Objective To investigate relationship between clinical pathological factors and prognosis in germinal center type (GCB) and non-germinal center type (non-GCB) diffuse large B-cell lymphoma. Methods A total of 98 patients with histologically and immunohistochemically diagnosed diffuse large B-cell lymphoma were divided by Hans immunophenotyping into 21 GCB cases (group A) and 77 non-GCB cases (group B). Survival rate was compared between the two groups, and influencing factors of prognosis were analyzed. Results Group A had higher survival rate than group B (P<0.05). The difference of lactate dehydrogenase (LDH) level and international prognostic index (IPI) shown by multivariate analysis had statistical significance between the two groups (P<0.05). LDH and IPI were the independent prognosis factors for diffuse large B-cell lymphoma. Conclusion Among diffuse large B-cell lymphoma cases, non-GCB ones are common. LDH and IPI scores are main influencing factors for non-GCB prognosis. Treatment measures should be made in accordance with actual condition of patients.

弥漫大B细胞淋巴瘤是临床上最常见的恶性淋巴瘤, 也是非霍奇金淋巴瘤中最常见的一种, 在各个年龄阶段均可发病, 其中以老年人多见, 大多患者就诊时处于Ⅱ~Ⅳ期, 虽然约40%的患者联合化疗可获得持续缓解, 但总体治疗效果不佳。事实上, 弥漫大B细胞淋巴瘤一经确诊和分级, 对影响预后的相关因素进行分析和评价, 进而制定个体化治疗方案, 患者是有希望获得治愈的。本文以本院病理科诊断为GCB型与non-GCB型弥漫大B细胞淋巴瘤的98例患者为研究对象, 对其预后因素进行分析, 现报告如下。
1 资料与方法
1. 1 一般资料 选取本院2008年11月~2010年11月收治的弥漫大B细胞淋巴瘤患者98例, 所有患者在入院后行病变淋巴结活检, 均经病理组织学证实, 并参照相关诊断标准明确诊断。……
