The authors report their results of a prospective double-blind study of 35 patients with squamous cell carcinoma of the esophagus conducted between February 1987 and February 1988. As all the patients were operated upon, we were able to define diagnostic accuracy (DA) of CT in determining the upper pole of the tumour, position of the tumour, invasion of trachea and bronchi, aorta, left auricle, vertebral column, pleura, pericardium and also abdominal invasion or thoracic lymph node. CT scanning slightly improved pre-operative evaluation of resectability of tumours when compared with routine barium swallow, abdominal US and bronchoscopy. It is not of great help for tumours smaller than 5 cm. CT scanning is particularly useful in evaluation of response to pre-operative chemotherapy.
作者报告了他们在1987年2月至1988年2月期间对35例食管鳞状细胞癌患者进行的前瞻性双盲研究结果。由于所有患者均接受了手术，我们能够确定CT在确定肿瘤上极、肿瘤位置、气管和支气管侵犯、主动脉、左心房、脊柱、胸膜、心包以及腹部侵犯或胸段淋巴结方面的诊断准确性（DA）。与常规钡餐、腹部超声和支气管镜检查相比，CT扫描在一定程度上改善了术前对肿瘤可切除性的评估。对于小于5厘米的肿瘤，其帮助不大。CT扫描在评估术前化疗反应方面特别有用。
