Methods： The clinical data of 88 patients of nasopharyngeal carcinoma with recurrent and persistent lymph nodes after radiotherapy were analyzed retrospectively. The levels of involved lymph nodes and the relationship among the levels were analyzed; the survival rate and recurrent rate of the surgical modes including radical neck dissection （RND）, modified radical neck dissection （MRND）, selective neck dissection （SND）, and lymph node resection （LNR） were analyzed; the role of postoperative radiotherapy was evaluated. Results： （1） The recurrent and persistent lymph nodes mainly located in level Ⅱ（55.6% and 58.6%, respectively）, next was level Ⅲ and rarely in level Ⅳ, Ⅴ, and Ⅰ, but the number of levels Ⅳ Ⅴ, and Ⅰ with cancer-bearing lymph nodes was relatively more than that of clinical measurement. （2） Patients with lymph nodes involved in level Ⅲ and Ⅳ, usually, have other levels involved simultaneously; the percentages were 63.6% and 88.9%, respectively. However, the lymph nodes in level Ⅱ and Ⅴ were mainly isolated. （3） The 5-year survival rate and recurrent rate of the whole group were 42.77% and 22.7%, respectively. （4） The 5-year survival rates of RND, MRND, SND, and LMR groups were 39.75%, 60.00%, 37.87%, and 44.10%, respectively; the differences were insignificant （Log-rank = 1.0, P = 0.8011）; the recurrent rate between the extensive and local surgery groups were insignificant （X^2 = 0.470, P = 0.493）. （5） The 5-year survival rates of the patients with and without postoperative radiotherapy were 39.06% and 45.26%, respectively; the difference was insignificant （Log-rank = 0.06, P = 0.8138）. Conclusion： The extensive surgery was recommended when the recurrent and persistent lymph nodes were more than one level involved or very large or immovable, otherwise, the SND should展开更多
