Abstract

PURPOSE: The objective of this study is to evaluate the contribution of induction (IC) or adjuvant (AC) chemotherapy additional to concurrent chemoradiotherapy (CCRT) for patients with T3-4N0-1 nasopharyngeal carcinoma (NPC) in the era of intensity-modulate radiotherapy (IMRT).

METHOD AND MATERIALS: We retrospectively reviewed the data on 685 patients with newly diagnosed T3-4N0-1 NPC. Propensity score matching (PSM) method was used to match patients. Survival outcomes between different groups were calculated by Kaplan-Meier method and compared using log-rank test. Cox proportional hazard model was adopted to establish independent prognostic factors.

RESULTS: In total, 236 pairs were selected from the primary cohort. Univariate analysis revealed 3-year overall survival (OS) (90.8% vs. 90.3%,

CONCLUSION: Patients with T3-4N0-1 NPC receiving CCRT could not benefit from additional induction or adjuvant chemotherapy in the era of IMRT.
