• BACKGROUND
    • To investigate the prognostic factors of Nasopharyngeal Carcinoma (NPC).
  • METHODS
    • Retrospective analysis was carried out on the clinical data collected from three hospitals in North China between September, 1999 to March, 2012.
  • RESULTS
    • Higher survival rates (1, 3, 5, and 10 year) were found in NPC patients who were female, non-smokers, early clinical phase, and T1-2 (p < 0.05). No association was found between survival rates and drinking habits, lesion location, pathological types, N stages, and radiotherapy pattern. The 1-, 3-, and 5-year overall survival rates were equal following both conventional radiotherapy and Intensity-Modulating Radiotherapy (IMRT).
  • CONCLUSIONS
    • Patient gender, age, smoking status, clinical stages, and T stages all served as prognostic factors of nasopharyngeal carcinoma.
