摘要:

目的 探讨骨髓血管内皮生长因子(VEGF)水平在弥漫性大B细胞淋巴瘤(DLBCL)疗效监测中的价值。方法 选取DLBCL患者40例,检测其治疗后的骨髓血浆VEGF 、乳酸脱氢酶(LDH)水平及血小板(PLT)计数,计算VEGF/PLT比值。收集所有患者的临床资料[年龄、性别、临床分期、美国东部肿瘤协作组(ECOG)评分、国际预后指数(IPI)评分、癌细胞是否侵入骨髓、是否有结外侵入、治疗反应(有效、无效)]。采用Spearman相关分析评估各参数间的相关性,采用Cox比例风险回归模型评估影响患者总生存时间(OS)和无进展生存时间(PFS)的危险因素,绘制Kaplan-Meier生存曲线。结果 年龄≥65岁、ECOG评分≥2分、IPI评分>3分及治疗无效的DLBCL患者骨髓VEGF水平较高,癌细胞未侵入骨髓的DLBCL患者PLT计数较高,年龄≥65岁、癌细胞侵入骨髓、IPI评分>3分及治疗无效的DLBCL患者VEGF/PLT比值较高。DLBCL患者骨髓VEGF水平与PLT计数呈正相关(r=0.33,P<0.05)。治疗有效组VEGF/PLT比值明显低于治疗无效组(P<0.05),而VEGF、PLT计数2个组之间差异均无统计学意义(P>0.05)。Kaplan-Meier生存曲线结果显示,VEGF/PLT比值<3×10-6 pg组的PFS、OS高于VEGF/PLT比值≥3×10-6 pg组(P<0.05)。Cox比例风险回归模型评估结果显示,VEGF/PLT比值是影响DLBCL患者PFS的危险因素[风险比(HR)=3.277,95%可信区间(CI)为2.276~5.901],ECOG评分、IPI评分、骨髓VEGF水平是影响DLBCL患者OS的危险因素(HR值分别为4.26、3.33、3.52,95%CI分别为3.102~5.466、2.257~5.009、2.620~4.104)。结论 骨髓VEGF水平与DLBCL患者预后有关。

Abstract:

Objective To investigate the role of bone marrow vascular endothelial growth factor(VEGF) levels in monitoring the curative effect of patients with diffuse large B-cell lymphoma(DLBCL). Methods Totally,40 patients with DLBCL were enrolled. The levels of VEGF,platelet(PLT) count and lactate dehydrogenase(LDH) in bone marrow plasma were determined after treatment,and the ratio of VEGF/PLT was calculated. The clinical data of patients [age,sex,clinical stage,the Eastern Cooperative Oncology Group(ECOG) score,international prognosis index(IPI) score,cancer cell invasion into bone marrow or not,invasion and treatment response(effective or ineffective)] were collected. Spearman correlation analysis was used to evaluate the correlation among the parameters. Cox proportional hazard regression model was used to evaluate the risk factors affecting the overall survival time(OS) and progression free survival(PFS),and the Kaplan-Meier survival curve was drawn. Results The level of VEGF in bone marrow of DLBCL patients with age≥65 years old,ECOG score≥2,IPI score>3 and ineffective treatment was higher. The PLT count of DLBCL patients whose cancer cells with bone marrow invasion was higher. The VEGF/PLT ratio of patients with age≥65 years old,cancer cells with bone marrow invasion,IPI score>3 and ineffective treatment was higher. There was a positive correlation between VEGF level and PLT count in DLBCL patients(r=0.33,P<0.05). The ratio of VEGF/PLT in effective group was lower than that in ineffective group(P<0.05),but there was no statistical significance in VEGF and PLT count between the 2 groups(P>0.05). Kaplan-Meier survival curve showed that the PFS and OS of VEGF/PLT ratio<3×10-6 pg group were higher than those of VEGF/PLT ratio≥ 3×10-6 pg group(P<0.05). Cox proportional hazard regression model showed that VEGF/PLT ratio was a risk factor for PFS in DLBCL patients [hazard ratio(HR)=3.277,95% confidence interval(CI) 2.276-5.901],and ECOG score,IPI score and bone marrow VEGF level were risk factors of OS in DLBCL patients(HR were 4.26,3.33 and 3.52,95%CI 3.102-5.466,2.257-5.009 and 2.620-4.104,respectively). Conclusions The level of VEGF in bone marrow is related to the prognosis of DLBCL patients.
