摘要 高级别B细胞淋巴瘤(high grade B-cell lymphomas,HGBL)是一种形态学和遗传学特征介于弥漫大B细胞淋巴瘤(diffuse Large B-Cell Lymphomas,DLBCL)和Burkitt淋巴瘤之间的高度侵袭性B细胞淋巴瘤。2016年世界卫生组织将其定义为一种独立的疾病^([1]),包括两种类型:伴有myc和bcl-2和/或bcl-6重排的双打击或三打击淋巴瘤(double/triple-hitlymphomas,D/THL);不伴myc和bcl-2或bcl-6重排的非特指型淋巴瘤(high grade B-cell lymphoma,not otherwise specified,HGBL,NOS)[1]。依据细胞起源又可将其分为生发中心B细胞(germinal center B-cell-like,GCB)和活化B细胞(activated B-cell-like,ABC)两种亚型(基因表达谱分型)^([2])。D/THL约占DLBCL的7.9%,多数为GCB亚型[3,4],好发年龄60~70岁,也可见于30岁左右的年轻人,男性多于女性。多数患者起病时即表现为广泛的疾病侵犯,如累及多个结外病变,骨髓及中枢侵犯。HGBL目前尚无标准的治疗方案,患者中位生存时间为0.2~1.5年,预后极差。本文报道利妥昔单抗联合来那度胺(R2)方案治疗高级别B细胞淋巴瘤1例并进行文献复习。
