BACKGROUND: The choice between endoscopic surgery and re-radiotherapy as the main treatment modality in patients with advanced recurrent nasopharyngeal carcinoma (rNPC) remains controversial. Therefore, in this study, we compared the efficacies of endoscopic surgery and intensity-modulated radiotherapy (IMRT) in patients with rNPC.
METHODS: All patients with advanced rNPC (T3 and T4) who underwent salvage treatment were enrolled from January 2009 to December 2020. Overall survival (OS) was analyzed using a log-rank analysis. Univariate and multivariate analyses of OS were performed using a Cox regression model. Common treatment-related complications of endoscopic surgery were compared with those of IMRT.
RESULTS: The numbers of patients with T3 and T4 tumors were 163 (64.2%) and 91 (35.8%), respectively; 192 patients underwent endoscopic surgery, 51 received IMRT, and 11 received three-dimensional conformal radiotherapy (3D-CRT). The 3-year OS of patients treated with endoscopic surgery was 59.3%, which was significantly higher than that of patients treated with IMRT (34.7%, p < 0.001) or 3D-CRT (43.6%, p = 0.012). Multivariate analyses showed that IMRT was an independent risk factor for OS compared with endoscopic surgery (hazard ratio, 2.068; 95% confidence interval, 1.395-3.069, p < 0.001). Complications of aural fullness (p = 0.001), nasopharyngeal necrosis (p = 0.004), nasopharyngeal hemorrhage (p = 0.004), dysphagia (p < 0.001), and cerebral infarction (p = 0.030) were significantly lower in the endoscopic surgery group than in the IMRT group.
CONCLUSION: Endoscopic surgery may be a more promising salvage treatment than IMRT to maximize survival and minimize treatment-related complications in advanced rNPC. These results will be significant in deciding the optimal treatment for patients with advanced rNPC.
