目的:探讨超声在复发鼻咽癌诊断中的应用价值。方法:对75例放疗后0.5～3.0年临床症状可疑复发的鼻咽癌患者行超声检查和CT检查,并全部行鼻内镜检查和病理活检,以评价超声检查诊断复发鼻咽癌的价值。结果:超声检查提示复发35例;病理确诊26例,假阳性9例,真阴性25例,假阴性15例。CT检查提示复发35例;病理确诊27例,假阳性8例,真阴性26例,假阴性14例。超声和CT诊断复发鼻咽癌的敏感度、特异性、准确性比较均差异无统计学意义,诊断价值类似。结论:超声和CT对复发鼻咽癌均具有良好的诊断价值,二者具有一定的互补性。
Objective: To investigate the value of ultrasound in the diagnosis of recurrent nasopharyngeal carcinoma. Methods: Totally 75 nasopharyngeal carcinoma patients with suspicious recurrent clinical symptoms from 0.5 to 3.0 years after radiotherapy were examined with ultrasound and CT, and all of them were examined by endoscopy and pathological biopsy to evaluate the value of ultrasound in the diagnosis of recurrent nasopharyngeal carcinoma. Results: Ultrasound examination showed 35 cases relapsed; 26 cases were pathologically confirmed, 9 cases were false positive, 25 cases were true negative and 15 cases were false negative. Twenty-five cases were recurred by CT, 27 cases were diagnosed by pathology, 8 cases were false positive, 26 cases were true negative and 14 cases were false negative. The sensitivity, specificity and accuracy of ultrasound and CT in the diagnosis of recurrent nasopharyngeal carcinoma had no statistical significance, and the diagnostic value was similar. Conclusion: Both ultrasound and CT have a good diagnostic value for recurrent nasopharyngeal carcinoma, both of which have certain complementarity.
