Abstract

Endoscopic endonasal nasopharyngectomy (EEN) has become increasingly used for recurrent nasopharyngeal carcinoma (rNPC) due to reduced functional and cosmetic morbidities compared to conventional external approach. Majority of the existing studies on EEN focused on patients with lower recurrent staging of rT1 and rT2. The aims of this study were to provide a preliminary report on the outcome of EEN performed in patients with advanced (rT3 and rT4) rNPC, and to determine the prognostic factors for patients’ survival. All patients who underwent EEN for rNPC between January 2003 and December 2015 inclusive were analyzed. All surgeries were performed in University Malaya Medical Centre in Kuala Lumpur and Queen Elizabeth Hospital in Sabah, by a single surgeon. We reported the 2-year overall survival (OS), disease-free survival (DFS) and disease-specific survival (DSS) and any related complications and significant prognostic factors. Fifteen patients with recurrent NPC (2 rT3 and 13 rT4 tumours) underwent EEN over the 13 years period. The mean age was 50.4 years (range 30–65) and the mean follow-up period was 28.7 months (range 9–81 weeks). The 2-year OS, DFS and DSS were 66.7 % (mean 19.4 months), 40 % (mean 15.7 months) and 73.3 % (mean 20.2 months), respectively. No severe operative complications were encountered. No independent prognostic factors for survival outcome were identified. This is the first preliminary report in English that exclusively looked at the use of EEN in advanced rT3 and rT4 NPCs, showing favourable patient outcome. However, further long-term follow-up of patients is required.
