摘要: 目的探讨鼻咽癌患者治疗前血浆纤维蛋白原水平与患者预后及肿瘤转移的相关性。方法收集2005年1月至2014年10月我院收治的817例非远处转移鼻咽癌患者的临床资料,并对患者进行随访,中位随访时间为37.6个月。通过受试者工作特征(ROC)曲线确定治疗前血浆纤维蛋白原的临界值。通过KaplanMeier方法和Cox回归模型分析患者总生存期(OS)和无远处转移生存期(DMFS)及其相关因素。结果通过ROC曲线分析确定治疗前血浆纤维蛋白原临界值为3.314 g/L。治疗前血浆纤维蛋白原水平与TNM分期(χ2=6.048,P=0.014)、T分期(χ2=13.764,P<0.001)、治疗后远处转移(χ2=14.637,P<0.001)相关。生存分析结果显示,治疗前血浆纤维蛋白原水平≥3.314 g/L的患者3年OS率和3年DMFS率显著低于治疗前血浆纤维蛋白原<3.314 g/L者,差异均有统计学意义(87.2%∶95.6%,χ2=4.562,P<0.001;71.1%∶82.2%,χ2=5.153,P<0.001)。Cox多因素分析结果显示,治疗前高水平血浆纤维蛋白原(HR=1.961,95%CI为1.332~2.917,P=0.001)、EB病毒DNA(HR=1.929,95%CI为1.275~2.849,P=0.001)和治疗前分期(HR=1.653,95%CI为1.013~2.709,P=0.045)是患者OS的独立影响因素;治疗前高水平血浆纤维蛋白原(HR=1.519,95%CI为1.142~1.964,P=0.002)和EB病毒DNA(HR=1.950,95%CI为1.483~2.555,P<0.001)是患者DMFS的独立影响因素。817例患者中179例(21.91%)在随访期间发生了转移,其中159例(88.83%)在治疗后3年内发生转移。638例未发生转移的患者治疗前血浆纤维蛋白原水平(3.197±1.009)显著低于179例发生转移的患者(3.351±1.042;t=5.089,P=0.024),并且显著低于87例发生骨转移的患者(3.430±1.004;t=6.752,P=0.009)、68例发生肺转移的患者(3.301±1.018;t=4.281,P=0.039)及71例发生肝转移的患者(3.413±1.107;t=6.398,P=0.011)。结论治疗前血浆纤维蛋白原水平可作为评估鼻咽癌患者预后的独立指标,并且与肿瘤转移相关。

Abstract: ObjectiveTo investigate the relationships between the plasma fibrinogen level before treatment and prognosis and tumor metastasis in patients with nasopharyngeal carcinoma. MethodsThe clinical data of 817 patients with nondistant metastasis nasopharyngeal carcinoma from January 2005 to October 2014 in our hospital were collected. All the patients were followed up, and the median followup time was 37.6 months. The critical value of plasma fibrinogen before treatment was determined by receiver operating characteristic (ROC) curve. The overall survival (OS) and distant metastasis free survival (DMFS) and their relevant factors were analyzed by KaplanMeier and Cox regression model. ResultsThe critical value of plasma fibrinogen before treatment was 3.314 g/L determined by ROC curve analysis. The plasma fibrinogen level before treatment was related to the TNM stage (χ2=6.048, P=0.014), T stage (χ2=13.764, P<0.001) and distant metastasis after treatment (χ2=14.637, P<0.001). Survival analysis showed that the 3year OS rate and 3year DMFS rate in patients with plasma fibrinogen level ≥3.314 g/L before treatment were significantly lower than those in patients with plasma fibrinogen level <3.314 g/L, with significant differences (87.2% vs. 95.6%, χ2=4.562, P<0.001; 71.1% vs. 82.2%, χ2=5.153, P<0.001). Cox multivariate analysis showed that high level of plasma fibrinogen before treatment (HR=1.961, 95%CI: 1.3322.917, P=0.001), EB virus DNA (HR=1.929, 95%CI: 1.2752.849, P=0.001) and pretreatment stage (HR=1.653, 95%CI: 1.0132.709, P=0.045) were the independent influencing factors of OS. The high level of plasma fibrinogen before treatment (HR=1.519, 95%CI: 1.1421.964, P=0.002) and EB virus DNA (HR=1.950, 95%CI: 1.4832.555, P<0.001) were the independent influencing factors of DMFS. Of the 817 patients, 179 patients (21.91%) had metastasis during the followup period, and 159 patients (88.83%) had metastasis within 3 years after treatment. The plasma fibrinogen level before treatment in 638 patients without metastasis (3.197±1.009) was significantly lower than that in 179 patients with metastasis (3.351±1.042; t=5.089, P=0.024), and was significantly lower than that in 87 patients with bone metastasis (3.430±1.004; t=6.752, P=0.009), 68 patients with pulmonary metastasis (3.301±1.018; t=4.281, P=0.039) and 71 patients with liver metastasis (3.413±1.107; t=6.398, P=0.011). ConclusionThe plasma fibrinogen level before treatment can be used as an independent index to predict the prognosis of patients with nasopharyngeal carcinoma, which is related to tumor metastasis.
