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
