摘　　要：目的探讨原发性中枢神经系统淋巴瘤(PCNSL)患者的预后因素及不同治疗方法的临床效果。方法回顾性分析1975年1月至2016年12月美国SEER数据库中4812例PCNSL患者的临床资料。其中男性2831例,女性1981例,男女比例为1.4∶1.0;发病年龄<60岁者2236例(46.47%),60~<75岁者1718例(35.70%),≥75岁者858例(17.83%);幕上肿瘤2417例(50.23%),幕下肿瘤299例(6.21%),脑内多发肿瘤554例(11.51%),其他或未指明部位的脑部肿瘤1542例(32.04%);弥漫大B细胞淋巴瘤(DLBCL)3513例(73.00%),非DLBCL 234例(4.86%),其他或未指明类型的淋巴瘤1065例(22.13%);治疗方式为单独活检的2010例(41.77%),单独部分切除61例(1.27%),单独完全切除54例(1.12%),活检+化疗2384例(49.54%),部分切除+化疗159例(3.30%),完全切除+化疗144例(2.99%)。采用单因素及多因素Cox回归模型分析影响患者总体生存的预后因素;采用Fine-Gray检验与竞争风险模型研究影响患者肿瘤特异性生存的预后因素;生存分析采用Kaplan-Meier法,并通过Log-rank进行比较。结果单因素及多因素Cox风险回归模型分析结果显示,影响PCNSL患者总体生存的独立预后因素包括年龄、种族、婚姻状态、肿瘤部位、病理学亚型、手术、化疗、合并其他恶性肿瘤、合并HIV感染等。Fine-Gray检验与竞争风险模型分析结果显示,影响患者肿瘤特异生存的独立预后因素包括年龄、种族、婚姻状态、肿瘤部位、病理学亚型、手术方式、化疗、合并其他恶性肿瘤、合并HIV感染,而性别与放疗均与肿瘤特异生存无明显相关性。与活检相比,PCNSL患者可能从手术切除中获益(部分切除:HR=0.805,95%CI:0.656~0.989,P=0.04;完全切除:HR=0.521,95%CI:0.414~0.656,P<0.01)。Kaplan-Meier生存分析结果显示,活检+化疗组中位生存时间为28个月(95%CI:24.497~31.503),单独活检组为2个月(95%CI:1.756~2.244),单独部分切除组为2个月(95%CI:1.410~2.590),单独完全切除组为19个月(95%CI:Objectives To explore the prognostic factors of primary central nervous system lymphoma(PCNSL)and to analyze the efficacy of different treatment methods.Methods Clinical data of 4812 patients with PCNSL in SEER database from January 1975 to December 2016 were retrospectively analyzed.Among them,2831 were male and 1981 were female,the ratio of male to female was 1.4∶1.0.There were 2236 cases(46.47%)under 60 years old,1718 cases(35.70%)aged 60 to 74 years old,and 858 cases(17.83%)aged 75 years old or above.Two thousand four hundred and seventeen cases(50.23%)had supratentorial tumors,299 cases(6.21%)had infratentorial tumors,and 554 cases(11.51%)had multiple brain tumors,1542 cases(32.04%)were other or unspecified location.Three thousand five hundred and thirteen cases(73.00%)had diffuse large B-cell lymphoma(DLBCL),234 cases(4.86%)had non DLBCL,1065 cases(22.13%)had other or unspecified types of tumor.The treatment included 2011 cases(41.77%)of biopsy,61 cases(1.27%)of subtotal resection(STR),54 cases(1.12%)of gross total resection(GTR),2384 cases(49.54%)of biopsy and chemotherapy,159 cases(3.30%)of STR and chemotherapy,144 cases(3.00%)of GTR and chemotherapy.Univariate and multivariate Cox regression models were used to analyze the prognostic factors affecting the overall survival of the patients.Fine-Gray test and competitive risk model were used to analyze the prognostic factors affecting cancer-specific survival.Kaplan-Meier method and Log-rank test was used for survival analysis.Results Univariate and multivariate Cox regression analyses showed that age,race,marital status,tumor site,pathological subtype,surgery,chemotherapy,combined with other malignant tumors,and HIV infection were the independent prognostic factors affecting the overall survival of PCNSL patients.The results of Fine-Gray test and competitive risk model analyses showed that age,race,marital status,tumor location,pathological subtype,surgical method,chemotherapy,combined with other malignant tumors,and HIV infection were independent progno
