At different stages of examination and treatment in esophageal cancer patients there arise a large number of diagnostic errors, making from 28.3% to 32.7% as shown by our findings. A primary x-ray examination fails to detect tumor in 13.8-19.2% of patients. Most frequently diagnostic errors were due to underestimation of the clinical symptoms (first of all dysphagia and pains in food passage along the esophagus); a long period of time elapsed since patients' referral till roentgenological examination, poor potentialities of the latter in terms of detecting early esophageal cancer. If esophageal cancer is reasonably suspected then esophagoscopy is felt to be mandatory in all cases with negative roentgenological findings. To timely recognize esophageal tumors and lessen the number of diagnostic errors, it seems rational to establish special centers for endoscopic examination (fiberoptic esophagogastroscopy), where this category of patients should be referred to.
在食管癌患者的不同检查和治疗阶段，会出现大量诊断错误，根据我们的研究结果，错误率在28.3%至32.7%之间。初次X线检查有13.8% - 19.2%的患者未能检测出肿瘤。最常见的诊断错误是由于对临床症状（首先是吞咽困难和沿食管食物通过时的疼痛）估计不足；从患者转诊到进行X线检查间隔时间过长，X线检查在检测早期食管癌方面的能力有限。如果合理怀疑患有食管癌，那么在所有X线检查结果为阴性的病例中，食管镜检查被认为是必不可少的。为了及时识别食管肿瘤并减少诊断错误数量，设立专门的内镜检查中心（纤维光学食管胃十二指肠镜检查）似乎是合理的，这类患者应转诊至该中心。
