摘要
Conclusion: The survival rates and prognostic factors for nasopharyngeal cancer (NPC) were found to be similar to the published series from endemic regions. Objectives: The purpose of this retrospective study was to evaluate treatment outcome and prognostic factors of NPC patients treated with radiotherapy or chemoradiotherapy in a non-endemic region. Methods: We analyzed clinical characteristics, treatment outcome, and prognostic factors of NPC patients in a non-endemic region, and compared our institution's results with the published literature including a similar patient population from endemic and non-endemic regions. Among 248 NPC patients, 71 (28.6%) were female and 177 (71.4%) were male with a median age of 48 years. Results: Within a median 59 months (range 22-178) of follow-up, local recurrence developed in 22 (8.9%), regional recurrence in 2 (0.8%), locoregional recurrence in 5 (2%), distant metastases in 21 (8.5%), and both locoregional recurrence and distant metastases in 8 (3.2%) patients. Five-year locoregional control (LRC), disease-free survival (DFS), disease-specific survival (DSS), and overall survival (OS) rates were 83.7%, 73%, 78.5%, and 71.1%, respectively. In multivariate analysis for LRC, cranial nerve involvement (CNI) (p = 0.009) and tumor response (p = 0.004); for DFS, age (p = 0.003), CNI (p = 0.02), AJCC T classification (p = 0.05), and tumor response (p = 0.01); for DSS, age (p = 0.003), CNI (p = 0.04), AJCC T classification (p = 0.04), and tumor response (p = 0.01); for OS, age (p < 0.001), AJCC T classification (p = 0.005), and tumor response (p < 0.001) were significant prognostic factors.
