摘要
本文选取食管癌患者252例,均采用16排CT扫描仪完成增强CT扫描,研究了增强CT在食管癌分期及预后评估中的应用价值。结果表明增强CT对食管癌患者T3和T4期诊断准确度高于T1期和T2期诊断准确度(P<0.05);对食管癌患者N0和N1期诊断准确度比较,差异无统计学意义(P>0.05)。随访时间至2017年10月,淋巴结密度均匀型患者近期疗效、2年局部控制率高于低密度型、边缘强化内部坏死型;低密度型近期疗效、2年局部控制率高于边缘强化内部坏死型(P<0.05)。淋巴结边缘规则患者近期疗效、2年局部控制率高于边缘不规则、明显外侵患者(P<0.05)。本文结果提示,增强CT在食管癌患者手术前临床分期、化疗患者预后中起到重要的评估作用,对患者后续治疗具有指导意义。
The purpose of this study was to investigate the application value of enhanced CT in the stage and prognosis evaluation of esophageal cancer.A total of 252 cases of esophageal cancer patients were selected for enhanced CT scan with 16-slice CT scanner.The diagnostic accuracy of enhanced CT in the T3 and T4 stages of esophageal cancer was higher than that in the T1 and T2 stages(P<0.05).There was no significant difference in the diagnostic accuracy of N0 and N1 stage by enhanced CT in patients with esophageal cancer(P>0.05).During the follow-up to October 2017,the short-term efficacy and 2-year local control rate of patients with homogeneous lymph node density were higher than those of patients with low-density and marginal enhanced internal necrosis;the short-term efficacy and 2-year local control rate of patients with low-density were higher than those of patients with marginal enhanced internal necrosis(P<0.05).The short-term efficacy and 2-year local control rate of patients with regular lymph node margin were higher than those with irregular lymph node margin and obvious invasion(P<0.05).It is suggested that enhanced CT plays an important role in the evaluation of preoperative clinical staging of esophageal cancer patients and prognosis of chemotherapy patients,and has guiding significance for the follow-up treatment of patients.
