2008年版WHO淋巴瘤分类出版以来的数年中,淋巴瘤病理相关的知识又有所更新。对于B细胞非霍奇金淋巴瘤,人们较关注那些高度侵袭而又异质的亚型(例如:弥漫性大B细胞淋巴瘤),并努力尝试在分子生物学基础之上建立起更好的分型方法。此,人们对于如何正确理解并处理明显的恶性淋巴瘤以及那些并不具有明确恶性行为、克隆性淋巴组织增生性疾病之间的“边界性”病变的兴趣也日益增长。另一方面,有关TNKT/NK细胞的亚群构成、细胞分化方面的研究进展以及新近认识到的外周T/NK细胞淋巴瘤中的遗传学异常和信号路径调节失常,也有助于我们更深入地了解这些肿瘤的生物学特性。临床惰性、克隆性T/NK细胞增生性病变、特别是发生于黏膜皮肤部位者,也愈发受到人们关注。这些新的知识进展会推动淋巴瘤分类不断向前演进。
Updated knowledge about lymphoma pathology has been accumulated ever since the publication of the current WHO classiifcation of lymphomas in 2008. For B-cell non-Hodgkin lymphomas, endeavors have been made for approaching a better classiifcation of those highly aggressive and heterogeneous subtypes (e.g., diffuse large B-cell lymphomas) on the molecular biological basis. In addition, there is a growing interest in understanding and deal-ing with the borders of overt malignant lymphomas and certain clonal lymphproliferative disorders that are not overtly malignant. On the other hand, recent advances in understanding the subsets of T and NK (T/NK)-cell lineage and their differentiation, as well as the genetic aberrations or dysregulated signaling pathways in their neoplastic counterparts, have provided us novel insights into the biology of peripheral T/NK-cell lymphomas. Indolent clonal T/NK-cell prolif-erations, especially those arising from the mucocutaneous sites, have also

2012年的第54届美国血液学会(ASH)年会对于淋巴瘤而言或许具有“革命性”的意义,会议上首次明确提出“远离化疗”治愈淋巴瘤的梦想.而这一观点的提出并非凭空想象.随着对淋巴瘤本质的认识愈加深入,针对淋巴肿瘤细胞表面抗原、细胞内信号转导通路和细胞微环境的靶向药物的研发已取得明显进展.特别是针对惰性B细胞淋巴瘤的靶向药物组合在临床研究中已显示出超越传统化疗方案联合靶向药物的疗效,而且安全性更好.靶向治疗在侵袭性B细胞淋巴瘤外周T/NK细胞淋巴瘤方面也显示了良好的前景,相信不久的将来定能有所突破.
The 54th ASH annual meeting should be considered as a revolution for treatment of lymphoma."Keep away from chemotherapy" will not be just a dream,it based on the deep understand of lymphoma genesis and quick development of different targeted agents.The typical examples are the dramatic novel agents targeting B cell receptor signaling pathway and microenvironment.There combination,such as R-square regimen,showed unbelievable efficacy in indolent B cell lymphomas and tiny side effects.It is sure that therapy breakthroughs in aggressive B cell lymphomas and T/NK cell lymphomas are in the very near future.

细胞因子诱导的杀伤细胞(CIK细胞)是人类外周血单个核细胞(PBMC)在体经干扰素-γ、抗CD3单克隆抗体、白细胞介素(IL)-2、IL-1等诱导培养而获得的一种新型免疫活性细胞.CIK细胞具有T细胞NK细胞的双重表面标志,在体内拥有强大的抗肿瘤活性,且兼有非主要组织相容性复合体(MHC)限制性的优点,是目前过继免疫治疗肿瘤的主要效应细胞,已被广泛应用于肝癌、肺癌等实体瘤及白血病、淋巴瘤、骨髓瘤等血液系统肿瘤的辅助治疗.文章就CIK细胞的优化培养及在血液系统恶性肿瘤治疗中的应用进展作一综述.
Cytokine induced killer (CIK) cells are a new kind of cytotoxic cells,which are generated by stimulation of peripheral blood mononuclear cells (PBMC) with IFN-γ,IL-2,IL-1 and anti-CD3 in vitro.These cells represent phenotype of both T cell and NK cell and have advantages of the non MHC restriction,so they have a strong ability of antitumor activity in vivo and vitro.Now,CIK cells as the main effector cells of adoptive immunotherapy have been extensively used in a variety of solid tumors such as liver cancer,lung cancer and hematological malignancies including leukemia,lymphoma,myeloma.In this article,the optimized cultivation of CIK cells as well as their most prominent clinical application in hematologic malignancies were summarized.

外周T/NK细胞淋巴瘤(PT/NKCLs)是一组高度异质性的T/NK细胞恶性肿瘤,在全球平均发病率低,具有明显的地域和种族差异性,亚洲人群相对高发,病理亚型差异性更显著,也是影响预后的最关键因素。目前治疗以CHOP类方案为主,因此初治高危的侵袭性PTCLs、二线挽救化疗有效的复发难治患者,均应考虑大剂量化疗联合造血干细胞移植,自体干细胞移植仍然作为首选。新的化疗药物,如Pralatrexate、苯达莫司汀等,对复发难治的PTCLs有效率约30%。靶向药物包括单抗类药物、针对细胞内信号传导通路的小分子抗体药物以及免疫调节药物,也在不同亚型PTCLs中取得一定疗效。本综述对PT/NKCLs诊治现状做一总结。
The peripheral T/NK cell lymphomas (PT/NKCLs) encompass a heterogeneous group of malignant lymphoid diseas-es, which derived from mature T-cells and NK cells. PT/NKCLs are rare, and its epidemiology and pathological subtypes showed signif-icant geographic and ethnic differences. PT/NKCLs, especially NK/T cell lymphoma (nasal type), are relatively common in Asian coun-tries. The use of an anthracycline-containing regimen is not associated with an improved outcome in most subtypes of PT/NKCLs, but is associated with an improved outcome in anaplastic large-cell lymphoma, ALK positive. High-dosage chemotherapy combined with stem cell transplantation is a considerable choice for newly diagnosed high-risk or refractory/relapsed PT/NKCLs because of its general-ly poor clinical outcome. Advances in new drugs have lagged behind DLBCL because of the disease rarity of PT/NKCL and biological heterogeneity. Nevertheless, new chemotherapeutic drugs, such as pralatrexate and bendamustine, a
目的:探讨非霍奇金淋巴瘤( NHL )免疫功能的变化及其临床意义。方法初治NHL患者50例为实验组,采集静脉血检测T细胞亚群、NK细胞及免疫球蛋白( Ig)水平,与30名健康对照者进行比较;并对50例患者中不同临床分期、有无B症状及治疗有效无效组进行比较。结果实验组外周血CD4+、 NK细胞计数及CD4+/CD8+比值均明显低于对照组(P<0.05),实验组与对照组的CD3+、CD8+、CD19+计数比较差异无统计学意义( P>0.05);实验组中,治疗无效组、有B组症状组、Ⅲ+Ⅳ期组的CD4+、NK细胞计数及CD4+/CD8+比值明显降低(P<0.05);实验组与对照组及实验组各亚组间的IgA、IgG 、IgM水平比较,差异均无统计学意义(P>0.05)。结论 NHL患者存在细胞免疫抑制,其临床分期、治疗疗效与细胞免疫功能有关,而与体液免疫的相关性有待进一步探讨。
