AbstractObjective To investigate the clinical efficacy of concurrent chemotherapy in intensity-modulated radiotherapy (IMRT) for patients with stage Ⅲ nasopharyngeal carcinoma (NPC). Methods Clinical data of 251 patients with stage Ⅲ NPC treated with IMRT alone or concurrent chemoradiotherapy (CCRT) at Sun Yat-sen University Cancer Center from February 2001 to December 2008 were retrospectively analyzed. The prognostic factors of NPC were analyzed and the efficacy of CCRT was assessed. The survival rate was calculated by Kaplan-Meier method. The differences between two groups were analyzed by log-rank test. The prognostic factors were analyzed by Cox model. Results The 10-year locoregional-free survival (LRFS), distant metastasis-free survival (DMFS), progression-free survival (PFS), and overall survival (OS) for NPC patients were 88.6%, 81.1%, 68.8% and 75.1%, respectively. Univariate and multivariate analyses demonstrated that N staging and nasopharyngeal tumor volume were the most important prognostic factors, and concurrent chemotherapy significantly improved PFS and OS (both P<0.05). In T3N0-1 patients, there was no significant difference in survival indexes between IMRT alone and CCRT (10y-LRFS:93.8% vs. 93.2%, P=0.933;10y-DMFS:80.9% vs. 86.8%, P=0.385;10y-PFS:70.6% vs. 77.7%, P=0.513;10y-OS:71.8% vs. 83.6%, P=0.207). For T1-3N2 patients, CCRT was significantly better than radiotherapy alone in LRFS, PFS, and OS (10y-LRFS:87.3% vs. 66.7%, P=0.016;10y-PFS:70.2% vs. 41.0%, P=0.003;10y-OS:78.5% vs. 51.7%, P=0.008), whereas there was an increasing trend in DMFS (10y-DMFS:80.3% vs. 66.4%, P=0.103). Conclusions Concurrent chemotherapy can improve clinical prognosis of stage Ⅲ NPC patients, and the most survival benefits are obtained in the N2 group. Individualized treatment options should be delivered based on the risk of treatment failure.
