Popis: Our aim was to review the outcomes of endoscopic nasopharyngectomy performed on a large series of patients with residual or recurrent nasopharyngeal carcinomas and to identify the prognostic factors. Ninety-one patients with residual (10) and recurrent (81) nasopharyngeal carcinomas who underwent endoscopic nasopharyngectomy were enrolled in our study. Clinical information including gender, age, medical history, symptoms, radiographic findings, tumor stage, treatment, recurrence time, postoperative pathological examination, complications, and outcomes at last follow-up visit was collected. The survival curves and multivariate survival analysis were analyzed using the Kaplan–Meier and Cox proportional hazards model. Our study included 71 men and 20 women with a median age of 51 years. The lesions were staged as follows: rT1, 30; rT2, 13; rT3, 29; and rT4, 19. No serious operative or postoperative complication was observed. The median follow-up period was 23 months (range, 4–109 months). Tumor necrosis was identified in 40 of 91 patients. At the last follow-up, 42 patients were free of disease, 10 were alive with disease, and 39 had died. At 2- and 5-year follow-up, the overall survival rates were 64.8% and 38.3%, respectively; the disease-free survival rates were 57.5% and 30.2%, respectively, for the two periods. Multivariate analysis showed that T classification (P = 0.02) and tumor necrosis (P = 0.024) were independent risk factors. Endoscopic nasopharyngectomy is a feasible and effective surgical treatment for recurrent and residual nasopharyngeal carcinomas.
