Abstract: Objectives: To explore the clinical evaluation of ultrasonography for cervical lymph nodes metastasis of nasopharyngeal carcinoma (NPC), and to clarify whether ultrasonography is useful in the clinical-staging of NPC. Methods: Fifty-nine patients of incipient nasopharyngeal carcinoma were given detail examination in cervical lymph nodes with ultrasonography before radiotherapy, and 121 lymph nodes were performed fine needle aspiration cytology(FNAC). Results: Of the 121 cervical lymph nodes, 83 were metastasis (68.6%), and most were in the superior group fields (33.7) and the posterior cervical group fields (51.8%). Almost all of them were lower-echo and noncalcification, and they had the following circumstance: rounded (79.5%), boundary (91.6%), envelope infringed (54.2%); 95.2 percent of them could not display the lymph node’s portal with high echo; few of them had putrescence (7.2%) and showed the distal acoustic enhancement (12.0%); many of them had abundant blood flowing signal (69.8%). The average PSV (peak systolic velocity) and RI (resistance index) was 27.5cm/s and 0.55, respectively. Conclusions: Ultrasonography was accurate in measuring lymph nodes of the neck of nasopharyngeal carcinoma, it could be some valuable to the diagnosis, the clinical staging and guiding treatment in nasopharyngeal carcinoma.
