目的对胸段食管癌病变长度的不同检测方法进行分析比较,探讨CT测量食管癌病变长度的准确性.为食管癌放疗靶区的精确勾俩提供理论依据.方法将598例胸段食管鳞状细胞癌患者经CT扫描、X线钡餐造影测量的病变长度与术中手术标本进行回顾性对比研究.对其间存在的差异进行分析.结果 CT扫描、X线钡餐造影、手术标本的食管病变半均长度分别为(6.70±2.52)cm、(5.13±1.91)cm和(5.23±1.93)cm.CT扫描的病变长度与手术标本比较差异有统计学意义(P=0.000);X线钡餐造影病变长度较手术标本偏短,但二者差异无统计学意义(JP=0.106);病变长度从大到小顺序依次为CT扫描、手术标本、X钡餐造影.结论 CT扫描的食管癌病变长度较手术标本实际肿瘤长度偏长,而X线钡餐造影稍偏短.在应用CT勾画食管癌放疗靶区判定病变长度时,应综合参考X线钡餐造影等其他检查.

Objective To compare accuracy of methods to measure lesion of thoracic segment esophageal carcinoma, and to provide the theory evidence for the precise sketch of irradiation targets.Methods A total of 598 patients with thoracic segment esophageal squamous cell carcinoma were enrolled in this retrospective study.Their lesion lengths were measured and compared respectively in intraoperative specimen,X-ray barium meal and CT.Results Measured mean lengths of lesion were respectively(6.70±2.52)cm,(5.13±1.91)cm and(5.23±1.93)cm in CT,X-ray barium meal and intraoperative specimen.There were significant differences in lesion lengths between intraoperative specimen and CT (P=0.000).There were no significant differences in lesion lengths between intraoperative specimen and X-ray barium meal(P=0.106).Lesion lengths were from top to bottom CT,intraoperative specimen and X-ray barium meal.There were no significant differences in lesion lengths between different pathological type,different T staging intraoperative specimen and X-ray barium meal(P＞0.05),but there were significant differences in lesion lengths between different pathological types(except intracavitary type),different T stagings intraoperative specimen and CT(P＜0.05). Conclusion Lesion length measured with CT is longer than that measured with intraoperative specimen,but it is shorter with X-ray barium meal than that with intraoperative specimen.It is suggested that X-ray barium meal and other examinations should be referred generally in using CT to depict esophageal carcinoma radiotherapy area.
