摘要
目的 分析CD70 在弥漫大B细胞淋巴瘤(DLBCL)中的表达情况,并探讨其与临床预后的相关性.方法 选取 2017 年 1 月—2021 年 12 月蚌埠医学院第一附属医院收治的初诊DLBCL患者 116 例,收集临床资料进行回顾性分析.检测肿瘤组织中CD70 的表达情况,分析CD70 表达在DLBCL患者中的临床意义.结果 116 例DLBCL患者中CD70 阳性表达率为 80.17%,其表达与中期评估疗效、有无B症状、骨髓是否受累、Ann Arbor分期相关(P＜0.05),而与性别、年龄、乳酸脱氢酶(LDH)、β2-微球蛋白(β2-MG)、B细胞淋巴瘤因子-2(BCL-2)、BCL-6、Ki-67、Hans分型、原发部位、国际预后指数(IPI)评分无显著相关性(P＞0.05).生存分析显示,CD70 阳性组与CD70 阴性组无进展生存期(PFS)和总生存期(OS)比较,差异有统计学意义(P＜0.05),CD70 阳性组患者预后更差.单因素分析显示,中期评估疗效、LDH、β2-MG、Ki-67、Hans分型、Ann Arbor分期、IPI评分及CD70 表达影响患者预后.多因素分析显示,中期评估疗效、Ki-67、Hans分型、CD70 是患者PFS的独立预后因素,中期评估疗效、β2-MG、Ki-67、Hans分型和CD70 是患者OS的独立预后因素.结论 CD70 在DLBCL中呈高表达,且与不良预后密切相关.
Abstract
Objective To analyze the expression of CD70 in diffuse large B cell lymphoma(DLBCL)and its corre-lation with clinical prognosis.Methods A total of 116 patients newly diagnosed with DLBCL who were admitted to the First Affiliated Hospital of Bengbu Medical College from January 2017 to December 2021 were selected and their clinical data were retrospectively analyzed.The expression of CD70 in tumor tissues was detected,and the clinical significance of CD70 expression in DLBCL patients was analyzed.Results The positive expression rate of CD70 in 116 DLBCL patients was 80.17%,and its expression was related to mid-term efficacy,B symptoms,bone marrow involvement and Ann Ar-bor stage(P＜0.05).However,CD70 expression was not associated with sex,age,lactate dehydrogenase(LDH),β2-microglobulin(β2-MG),B-cell lymphoma-2(BCL-2),BCL-6,Ki-67,Hans classification,primary site and inter-national prognostic index(IPI)score(P＞0.05).Survival analysis showed that the progression free survival(PFS)and overall survival(OS)of the CD70 positive group were significantly higher than those in the CD70 negative group(P＜0.05),and the prognosis of CD70 positive patients was worse.According to univariate analysis,the prognosis of DLBCL patients was affected by efficacy,LDH,β2-MG,Ki-67,Hans classification,Ann Arbor stage,IPI score and CD70 ex-pression.Multivariate analysis showed that mid-term efficacy,Ki-67,Hans classification and CD70 were the independ-ent prognostic factors for PFS,and mid-term efficacy,β2-MG、Ki-67、Hans subtype and CD70 were the independent prognostic factors for OS.Conclusions CD70 is highly expressed in DLBCL and strongly associated with poor prognosis.
