In a prospective study, 83 patients with esophageal carcinoma were examined by computed tomography. The CT data were compared with intraoperative, postmortem and microscopical findings in 74 patients. The T stage as determined by computed tomography was confirmed by surgery or autopsy in 88% of the cases and by microscopical examination in 82%. Infiltration of surrounding structures could be proved with a sensitivity of 87%, a specificity of 91% and an accuracy of 89%. Suspected lymph nodes were detected by computed tomography in 68% of the patients with lymph node metastases. Computed tomography enabled additional information on localisation, length and diameter of the tumors and the existence of metastases in the liver, lung and pleura. Due to the very good correlation between pre- and postoperative staging, computed tomography gives important information on local tumor resectability. In this manner, operations and therapeutic strategy can be planned with greater accuracy, and diagnostic thoracotomy can be reduced to a minimum.
在一项前瞻性研究中，对83例食管癌患者进行了计算机断层扫描检查。将74例患者的CT数据与术中、尸检及显微镜检查结果进行了比较。通过计算机断层扫描确定的T分期在88%的病例中经手术或尸检得到证实，在82%的病例中经显微镜检查得到证实。对周围结构浸润的诊断敏感性为87%，特异性为91%，准确性为89%。在68%有淋巴结转移的患者中，计算机断层扫描检测到了可疑淋巴结。计算机断层扫描能够提供有关肿瘤定位、长度、直径以及肝、肺和胸膜转移情况的额外信息。由于术前和术后分期之间具有很好的相关性，计算机断层扫描可为局部肿瘤的可切除性提供重要信息。通过这种方式，可以更准确地规划手术和治疗策略，并将诊断性开胸手术减少到最低限度。
