          摘  要  目的  探索非霍奇金淋巴瘤患者 MS4A1 基因多态性对利妥昔单抗血药浓度及疗效的影响。方法  选择 2016 年 1 月至
          2020年12月在中山大学肿瘤防治中心接受R-CHOP方案的新确诊非霍奇金淋巴瘤患者160例进行前瞻性观察性研究,最短随访
          时间约 5 年。以酶联免疫吸附试验测定患者利妥昔单抗血药浓度。采用 Haploview 4.2 软件挑选 MS4A1 基因位点:rs1051461、
          rs17155034、rs4939364、rs10501385,以基质辅助激光解吸电离-飞行时间质谱法分析患者的基因型。采用单因素线性回归分析患
          者各因素(人口统计学、临床指标与基因型)与第 1 个疗程利妥昔单抗稳态谷浓度的相关性,并进行多元线性回归分析。绘制
          Kaplan-Meier曲线以评估患者的无进展生存期(PFS)和总生存期(OS)。以MS4A1基因型和肿瘤分期为自变量,采用Cox回归模
          型评估影响患者预后的因素。结果  携带 MS4A1 rs10501385 CC 基因型患者的利妥昔单抗血药浓度为 15.20 μg/mL,显著低于
          AA+AC型患者的21.95 μg/mL(P<0.05)。以患者肿瘤分期和MS4A1 rs10501385基因多态性建立的利妥昔单抗血药浓度多元线
          性回归模型能解释7.3%的个体差异。与携带MS4A1 rs1051461 CC基因型患者比较,CT+TT基因型患者的PFS和OS均显著延长
         (P<0.05)。Cox回归模型显示,MS4A1 rs1051461 CC基因型(HR=4.406,95%CI为1.743~11.137,P<0.05)和肿瘤分期Ⅲ或Ⅳ期
         (HR=3.233,95%CI 为 1.413~7.399,P<0.05)是影响患者 PFS 的独立危险因素。结论  非霍奇金淋巴瘤患者的肿瘤分期和
          MS4A1 rs10501385位点多态性是利妥昔单抗血药浓度的关键影响因素,而肿瘤分期和MS4A1 rs1051461位点多态性能显著影响
          非霍奇金淋巴瘤患者的PFS。

          ABSTRACT   OBJECTIVE  To explore the effects of CD20 coding gene (MS4A1) polymorphism on the blood concentration and
          efficacy  of  rituximab  in  patients  with  non-Hodgkin’s  lymphoma.  METHODS  A  prospective  observational  study  was  conducted  on
          160  newly  diagnosed  non-Hodgkin’s  lymphoma  patients  who  received  the  R-CHOP  regimen  at  the  Sun Yat  Sen  University  Cancer
          Center from January 2016 to December 2020, with a minimum follow-up period of approximately 5 years. The blood concentration
          of  rituximab  was  detected  by  enzyme-linked  immunosorbent  assay.  MS4A1  tagSNPs  were  selected  by  Haploview4.2  software,
          including  rs1051461,  rs17155034,  rs4939364,  and  rs10501385.  The  genotype  of  MS4A1  was  detected  by  Matrix-assisted  laser
          desorption/ionization time-of-flight mass spectrometry. Univariate linear regression analysis was employed to examine the correlation
          between  various  factors(demographic,  clinical,  and  genotypic  variables)  in  patients  and  the  steady-state  trough  concentration  of
                                                             rituximab  during  the  first  course  of  treatment,  followed  by
