  • Purpose Over the past years, radiotherapy techniques have changed significantly. The impact of these changes in the management of nasopharyngeal carcinoma (NPC) has not been fully evaluated.

    Methods/patients Between 1984 and 2014, 223 NPC were diagnosed in our hospital. Prior to 2000, patients were treated with 2D treatment plan (RT2D) that evolved to 3D schemes thereafter (RT3D).

    Results Tumors in the RT3D period showed significantly lower stages than those in the RT2D period. 5-year cause-specific survival improved from 55.7% (95% CI: 46.7–64.7%) in the RT2D period to 78.7% (95% CI: 68.7–88.7%) in the RT3D period (P = 0.006). This difference was greater for non-keratinizing NPC, where specific survival went from 63.2% (95% CI: 52.2–74.2%) to 84.4% (95% CI: 74.4–94.4%) (P = 0.014).

    Conclusion Recent changes in treatment strategies including concurrent chemoradiation and 3D radiotherapy may have impacted in better survival for NPC. Improved imaging techniques may have contributed by earlier detection and better treatment planning.
