Abstract
Surgical access for retropharyngeal lymph node (RPLN) dissection is difficult. We aimed to examine the efficacy of transcervical endoscopic RPLN dissection (TSE-RPLND) for recurrent RPLN in nasopharyngeal carcinoma (NPC). From April 2013 to February 2019, a total of 31 patients with NPC diagnosed with RPLN recurrence underwent TSE-RPLND. The clinical characteristics, complications, and survival outcomes were retrospectively analyzed. The mean duration of surgery, quantity of bleeding and postoperative hospitalization stay were 347.9 minutes, 107.7 mL, and 8.7 days, respectively. After a median follow-up of 31.0 months, the 2-year locoregional relapse-free survival, distant metastasis-free survival, progression-free survival, and overall survival rates were 63.9%, 95.2%, 59.9%, and 83.3%, respectively. The long-term incidences of swallowing problems, permanent nutrient tube, tongue atrophy, and shoulder problems were 6 (19.4%), 3 (9.7%), 3 (9.7%), and 3 (9.7%), respectively. TSE-RPLND is an effective method to treat RPLN recurrence in NPC, but nerve injury-related complications should not be ignored.
