摘要:
目的 研究术前血清癌抗原19-9(cancer antigen 19-9,CA19-9)和神经元特异性烯醇化酶(neuron-specific enolase,NSE)对食管鳞癌(esophageal squamous cell carcinoma,ESCC)患者预后的影响。 方法 前瞻性分析176例经病理确诊的食管鳞癌新发病例。应用χ2检验分析CA19-9和NSE与患者一般临床特征之间的关系。运用Kaplan-Meier法绘制生存曲线,通过Log-rank法进行生存率的比较,利用Cox比例风险回归模型进行多因素分析。 结果 高CA19-9和NSE联合检测组的食管鳞癌患者预后较差(总生存:HR=2.310,95%CI:1.209~4.418;无病生存:HR=2.354,95%CI:1.265~4.381)。相比于两种标志物单独检测,联合检测CA19-9和NSE对食管鳞癌患者生存预测的准确性更高(总生存:C-index=0.686;无病生存:C-index=0.684)。 结论 术前血清CA19-9和NSE是食管鳞癌患者预后的危险因素,联合检测对食管鳞癌患者预后预测的准确性更高。 -

Abstract:Objective To explore the effects of preoperative serum cancer antigen 19-9 (CA19-9) and neuron-specific enolase (NSE) on the prognosis of patients with esophageal squamous cell carcinoma (ESCC). Methods This prospective study enrolled 176 patients with ESCC. χ2 test was used to analyze the relationship between CA19-9, NSE and general clinical features. Survival curves were estimated using Kaplan-Meier method and comparisons were performed using the log-rank test. The Cox proportional hazards model was performed for multivariate analyses of overall survival (OS) and disease free survival (DFS). Results The patients with both high CA19-9 and NSE had the poor prognosis compared with those had both low CA19-9 and NSE (OS: HR=2.310, 95% CI: 1.208-4.418; DFS: HR=2.354, 95% CI: 1.265-4.381). Compared to the separate detection of the two markers, the combined detection of CA19-9 and NSE was more accurate in the prognosis prediction of patients with ESCC (OS: C-index=0.686; DFS: C-index=0.684). Conclusions Preoperative serum CA19-9 and NSE were risk factors for the prognosis of patients with ESCC. Combined detection had higher accuracy of prediction of prognosis in patients with ESCC. -
