目的：探讨高频超声对颈段食管癌ＴＮＭ分期的价值。方法：应用经颈高频探头超声对２４例颈段食管癌进行了ＴＮＭ分期的研究。结果：经颈高频探头超声能１００％显示经颈段食管癌，并能进行ＴＮＭ分析，符合率高达９２．１％，可指导临床制定手术或放疗方案。
Objective: To investigate the value of high-frequency ultrasound in TNM staging of cervical esophageal cancer. Methods: Twenty-four cases of cervical esophageal carcinoma were studied by TNM staging using transthoracic high-frequency probe. RESULTS: Transthoracic high-frequency probe ultrasound showed 100% cervical transesophageal carcinoma and was able to perform TNM analysis. The coincidence rate was as high as 92.1%, which could guide the clinical development of surgery or radiotherapy.
