弥漫大B细胞淋巴瘤合并淋巴浆细胞淋巴瘤/华氏巨球蛋白血症伴IgM及IgG共存的临床研究

Clinical study of diffuse large B-cell lymphoma combined with lymphoplasmacytic lymphoma/Waldenstr m macroglobulinemia with biclclonic IgM and IgG

目的 探讨弥漫大B细胞淋巴瘤合并淋巴浆细胞淋巴瘤/华氏巨球蛋白血症(LPL/WM)伴免疫球蛋白M(IgM)及免疫球蛋白G(IgG)共存的发病机制、诊断标准、治疗方案及预后。方法 分析1例弥漫大B细胞淋巴瘤合并LPL/WM伴IgM及IgG共存患者的临床资料,以“弥漫大B细胞淋巴瘤”“免疫球蛋白”“单克隆”“IgM”“IgG”“淋巴浆细胞淋巴瘤”“华氏巨球蛋白血症”“diffuse large B-cell lymphoma”“immune globulin”“monoclonal”“lymphoplasmacytic lymphoma”“Waldenstr9m macroglobulinemia”为检索词,对中国知网数据库、万方知识服务平台及PubMed数据库中2017年1月至2023年6月发表的文献进行检索。结果 该例患者明确诊断为弥漫大B细胞淋巴瘤合并LPL/WM伴IgM及IgG共存,确诊后经环磷酰胺+多柔比星+长春新碱+泼尼松(CHOP)方案、环磷酰胺+长春新碱+泼尼松(COP)方案治疗有效,但治疗期间病情进展,从发病到死亡存活10个月。依照上述检索条件并经过阅读文献题目与摘要筛选出7篇文献。阅读全文共筛出11例双克隆免疫球蛋白共存LPL/WM患者,其中IgM伴IgG双克隆6例,IgM伴免疫球蛋白A(IgA)双克隆2例,IgG伴IgA双克隆2例及IgMκ伴IgMλ双克隆1例。文献中提到的治疗方案主要包括硼替佐米+利妥昔单抗方案、COP方案、CHOP方案等,上述方案联合化疗均有效,但该病的发病机制尚不明确,尚无标准的治疗方案及确切的生存期。结论 弥漫大B细胞淋巴瘤合并LPL/WM伴IgM及IgG共存系首次报告,因该病发病率极低,发病机制尚不明确,因此目前尚无统一的治疗方案,预后尚不明确,临床需进一步提高对该病的认识,未来对于其发病机制及新型分子靶向药物的应用进行深入研究,将会大大改善患者的预后。

,7 literatures were selected.A total of 11 patients with double clonal immune globulin co-existing LPL/WM were screened,including 6 patients with IgM and IgG double clonal,2 patients with IgM and immunoglobulin A(IgA)double clonal,2 patients with IgG and IgA double clonal,and a patient with IgMκand IgMλdouble clona.The treatment regiments mentioned in the literature mainly include bortezomib+rituximab regimen,COP regimen,CHOP regimen,etc.All of which were effective in combination with chemotherapy,but the pathogenesis of the disease was still unclear,and there was no standard treatment regimen and exact survival period.Conclusion The diffuse large B-cell lymphoma combined with LPL/WM with IgM and IgG is reported for the first time.Because the incidence of the disease is very low,and the pathogenesis is still unclear,there is no unified treatment regimen,and the prognosis is still unclear.In the future,in-depth research on its pathogenesis and the application of new molecular targeted drugs will greatly improve the prognosis of patients.
