Preoperative X-ray computerized tomography (CT) was performed in 60 patients with carcinoma of the esophagus at the All-Union Oncology Research Centre, USSR AMS in 1986-1989. The method is evaluated on the basis of comparison with the operative findings in determining the depth of invasion of the esophageal wall and adjoining structures by the tumor, metastatic involvement of the lymph nodes below the diaphragm, and metastases in the liver. Informativeness of X-ray CT proved to be highest in patients in whom the tumor had not spread beyond the esophageal wall. It was established that the method possesses high resolving possibilities in identification of enlarged lymph nodes in the abdominal cavity. Small metastases in the liver, measuring 0.5 to 2 cm in diameter, cannot be revealed by the method in some cases. The data gained by means of X-ray CT allows tactics of the surgical intervention to be determined and the late-term results to be predicted.
1986年至1989年期间，苏联医学科学院全联盟肿瘤研究中心对60例食管癌患者进行了术前X线计算机断层扫描（CT）。通过与手术结果进行比较，对该方法在确定肿瘤侵犯食管壁及毗邻结构的深度、膈肌以下淋巴结的转移情况以及肝脏转移方面进行了评估。事实证明，X线CT对肿瘤未超出食管壁的患者信息价值最高。已确定该方法在识别腹腔内肿大淋巴结方面具有很高的分辨能力。在某些情况下，该方法无法发现直径为0.5至2厘米的肝脏小转移灶。通过X线CT获得的数据有助于确定手术干预策略并预测远期结果。
