Sumario:BACKGROUND: With the coming of the aging society, the incidence of elderly nasopharyngeal carcinoma (NPC) has been increasing which may result in considerable disease burden; however, the optimal treatment strategy for elderly patients is still debatable. METHODS AND RESULTS: Clinical data on 294 elderly NPC patients aged ≥70 treated between 2009 and 2019 was analyzed. Kaplan–Meier method was used to estimate overall survival (OS) and cancer‐specific survival (CSS) rates. With a median follow‐up of 53.25 months, the 5‐year estimated OS and CSS for the entire group were 59.5% and 69.8%, respectively. 146 patients died within the follow‐up period, of which recurrence + metastasis (48%) and internal medical disease unrelated to NPC (32%) are the primary causes of death. On univariable analysis, (IMRT vs. 3D‐CRT) (p = 0.001; p = 0.000), T stage (p = 0.001; p = 0.000), N stage (p = 0.013; p = 0.000) and clinical stage (p = 0.000; p = 0.000) were associated with OS and CSS; Charlson Comorbidity Index (CCI) (p = 0.016) was associated with OS. The addition of chemotherapy (CT) correlated with better CSS (p = 0.039), but did not improve OS (p = 0.056) for stage III–IV subgroup. On multivariate analysis, advanced clinical stage independently predicted poorer OS (p = 0.002) and CSS (p = 0.000). In addition, the application of IMRT was an independent protective factor on both OS (p = 0.028) and CSS (p = 0.030). CONCLUSION: IMRT is a reasonable treatment strategy to improve survival for elderly NPC patients aged over 70 years; consideration of adding chemotherapy for elderly population should be weighed carefully.
