摘  要:目的 研究伴髓样分化因子88 (MyD88) L265P突变淋巴浆细胞疾病患者的临床特征.方法 采用突变扩增系统PCR-毛细管电泳(ARMS PCR-CE)法检测81例淋巴浆细胞疾病患者中MyD88 L265P突变的分布,结合患者的临床特征进行分析.结果 81例患者中MyD88 L265P突变阳性者25例(30.9%),其中以华氏巨球蛋白血症(WM)多见(77.8%,14/18),后依次为淋巴浆细胞淋巴瘤(66.7%,2/3)、急性淋巴细胞白血病(50.0%,1/2)、多发性骨髓瘤(30.0%,3/10)、意义未明的单克隆丙种球蛋白病(25.0%,1/4)、慢性淋巴细胞白血病(13.0%,3/23)、淋巴瘤(4.8%,1/21).25例突变患者中20例(80.0%)为IgM型.与未突变组患者比较,突变组患者年龄较大(67对55岁,P<0.001)、WBC较低(5.23×10^9/L对10.80×10^9/L,P=0.001)、HGB较低(85对119 g/L,P<0.001).结论 MyD88 L265P突变多见于IgM型淋巴浆细胞疾病,以WM多见,与未突变者比较,伴此突变者年龄较大,WBC、HGB较低.其预后意义尚需进一步研究予以明确.Objective To explore the clinical features oflymphoplasmacytic diseases with MyD88 L265P mutation.Methods To analyze the distribution of MYD88 L265P mutation in patients with lymphoplasmacytic diseases by using of ARMS PCR-CE.Results There were 25(30.9%) MyD88 L265P mutated patients in 81 patients.The mutation was frequently observed in 14 patients with WM (77.8%,14/ 18),2 patients with lymphoplasmacytic lymphoma (66.7%,2/3),1 acute lymphocytic leukemia patient (50.0%,1/2),3 multiple myeloma patients (30.0%,3/10),1 patient with monoclonal gammopathy of undetermined significance (25%,1/4),3 patients with chronic lymphocytic leukemia (13.0%,3/23) and 1 lymphoma patient (4.8%,1/21).20 (80%,20/25) patients were identified with IgM subtype.Compared with wild-type group of 56 cases,mutated patients were older (median age:67 years vs 55 years,P〈 0.001),with lower WBC count (median count:5.23 × 10^9/L vs 10.80× 10^9/L,P=0.001),lower HGB level (median count:85 g/L vs 119 g/L,P〈0.001).Conclusion MyD88 L265P mutation was mainly observed in patients with IgM subtype lymphoplasmacytic diseases,and Waldenstrom's macroglobulinemia was the most common disease.Compared with the wild-type group,patients with MyD88 L265P mutation were older and had lower WBC count,lower level of HGB.However,further studies were needed to test the prognostic value of MyD88 L265P mutation.
