目的 分析食管癌的CT表现,以便进行其分期。方法 分析25例手术及病理证实的食管癌胸部及上腹部的CT表现,包括病变的范围、周围纵隔结构的侵犯、淋巴结及纵隔外脏器的转移情况。结果 CT表现与病理检查的结论进行比较(其中21名进行食管癌切除手术),CT判断食管癌对纵隔脏器的侵犯的正确率90.48％(19/21),食管癌引起周围淋巴转移情况的正确率为76.42％(15/21)。4例CT检查发现有远处转移,避免了不必要的手术治疗。结论 CT检查对食管癌的术前分期,对病变范围进行评估,对降低不必要的手术治疗较为有效。
Objective To analyze the CT appearance of esophageal cancer so as to carry out its staging. Methods CT findings of 25 cases of esophageal cancer on the chest and upper abdomen confirmed by surgery and pathology were analyzed, including the extent of lesions, invasion of surrounding mediastinal structures, and metastasis of lymph nodes and mediastinum. Results CT findings were compared with those of pathological examination (21 of them performed esophageal cancer resection). The accuracy of CT in judging the invasion of mediastinal organs by esophageal cancer was 90.48% (19/21). Peripheral lymph node metastasis was caused by esophageal cancer. The correct rate is 76.42% (15/21). CT scans in 4 cases revealed distant metastasis and avoided unnecessary surgical treatment. Conclusions CT examination of preoperative staging of esophageal cancer and assessing the extent of lesions is more effective in reducing unnecessary surgical treatment.
