ABSTRACT
OBJECTIVE@#The purpose of this article is to discuss the clinical value of central neck lymph node dissection in papillary thyroid carcinoma, especially in thyroid papillary microcarcinoma (PTMC). Also this article wants to evaluate the diagnostic significance of preoperative ultrasonography of central neck metastasis lymph nodes and the clinical significance of preoperative ultrasonography in central neck lymph node dissection.@*METHOD@#Collected and analyzed 121 cases from September 2012 to December 2013. All of them had done the central neck lymph node dissection with the same standard by the same surgeon in our department. Evaluate the value of preoperative ultrasound diagnostic in thyroid microcarcinoma and non-microcarcinoma.@*RESULT@#In the 121 patients, The 62 patients were diagnosed with PTMC (primary lesion d≤1. 0 cm). Accuracy rate of ultrasound diagnostic was 74. 2% (46/62), the rate of missed diagnosis was 61. 9% (13/21), the rate of misdiagnosis was 7. 3 % (3/41), sensitivity was 38. 1% (8/21), specificity was 92.7% (38/41), positive predictive value was 72. 7% (8/11), negative predictive value was 74. 5% (38/51) and the value of Kappa was 0. 3485. The other 59 patients was diagnosed with thyroid papillary non-microcarcinoma (primary lesion d>1. 0 cm). The accuracy rate was 55. 9% (33/ 59), the rate of missed diagnosis was 58. 3% (21/36), the rate of misdiagnosis was 21. 7% (5/23), sensitivity was 41. 7% (15/36), specificity was 78. 3% (18/23), positive predictive value was 75. 0% (15/20), negative predictive value was 46. 2% (18/39) and the value of Kappa was 0. 1757.@*CONCLUSION@#Cervical central lymph node dissection was necessary when the ultrasound diagnosis of cervical central lymph node-positive was prompted suspiciously in the thyroid papillary microcarcinoma. However, when it prompted negative, we could recommend patients to do the prophylactic central lymph node dissection in conjunction with the risk factors. Whether the ultrasound diagnosis of central lymph node was prompted suspiciously or not in the thyroid papillary microcarcinoma and non-microcarcinoma, the central lymph nodes dissection is necessary.
