摘要
目的研究食管癌外侵的CT特点。方法对35例手术病理证实的食管癌的CT资料进行回顾性分析,结合文献复习,评价其CT表现及诊断意义。结果本文35例手术切除病例,术前CT表现为管壁不规则增厚,食管癌侵犯周围组织,术前CT诊断主动脉受侵20例,敏感度、特异度及正确诊断指数(约登指数)分别为86.7%、65.0%、0.517;气管-支气管、心包受侵分别为13例、4例,正确率为60%及50%;淋巴结增大75枚,灵敏度为56.2%,特异度3.1%,阳性预测值17.3%,阴性预测值16.7%;术前CT分期Ⅱ期10例,Ⅲ期10例,Ⅳ期15例。结论CT有助于判断食管癌是否侵犯邻近组织结构,便于指导临床采取相应的治疗措施。
Objective To study the CT evaluation of local invasion of esophageal carcinoma. Methods The CT findings of 35 cases of esophageal carcinoma, proved by pathohistology, were retrospectively investigated. Diagnostic findings were highlighted through a review of articles previously released. Results In total 35 patients with esophageal carcinoma underwent surgical resection. The findings of CT included irregular thickening of the esophageal wall and the adjacent structure involvement. Aortic invasion was concluded in the pre-operative diagnosis in 20 cases, in which the sensitivity, specificity and Youden index were 86. 7%, 65. 0%, 0. 517, respectively. Thirteen patients and four patients were pre - operatively diagnosed as tracheobronchial invasion and pericardiac invasion, in which the rate of accuracy were 60% and 50%. Seventy five lymph nodes were assessed on CT scan before surgery. The sensitivity and specificity of CT evaluation of lymph node were 56. 2% and 3.1%, and the positive predict value and negative predict value were 17.3% and 16. 7%, respectively. CT staging of esophageal carcinoma were stage Ⅱ in 10 cases, stage Ⅲin 10 cases and stage Ⅳ in 15 cases, respectively. Conclusion CT provides precise information of the local invasion of esophageal carcinoma, which is an valuable guidance for the clinical management.
