The Chi-squared test and Cox proportional hazard regression model were used to investigate associations between survival and clinicopathological features. Cumulative survival plots were obtained using the Kaplan\u2013Meier method.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Data analysis using the Cox proportional hazard regression model revealed that the size of residual or recurrent lymph node metastases, level V lymph node involvement, number of involved levels, surgical procedure performed, and distant metastases were significantly associated with overall survival. Chi-squared analysis only determined a significant correlation between distant metastases and patient survival. Furthermore, the Kaplan\u2013Meier analysis demonstrated that the 1-, 3-, and 5-year survival rates for patients were 86.6%, 52.2%, and 38.6%, respectively. Radical neck dissection resulted in substantially longer overall survival than modified neck dissection.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>The size of residual or recurrent lymph node metastases, level V lymph node involvement, number of involved levels, surgical procedure performed, and presence of distant metastases were prognostic factors for nasopharyngeal carcinoma patients with residual or recurrent cervical lymph node metastases after radiotherapy, with distant metastases being the most important determinant.
