Summary

Several prospective randomized trials have demonstrated that concurrent chemoradiotherapy was superior to radiotherapy alone in the treatment of locoregionally advanced nasopharyngeal carcinoma (NPC). Based on these evidences, concurrent chemoradiotherapy (CCRT) with/without sequential chemotherapy has become the standard care for locoregionally advanced NPC. However, most of these evidences of standard treatment for locoregionally advanced NPC were based on the two-dimensional conventional radiotherapy (2DCRT). As the intensity-modulated radiation therapy (IMRT) technique has been widely used in the last decades, IMRT improved the treatment outcomes of patients with NPC, especially the local control rate. Currently, more retrospective studies compared the IMRT alone vs. IMRT plus concurrent chemotherapy, and reported that concurrent chemotherapy failed to improve survival rates for patients with locoregionally advanced disease, but increased the severity of acute toxicities. People started to reconsider the role of CCRT. Therefore, we propose this randomized phase III non-inferiority study to reassess the efficacy and contribution of concurrent chemotherapy in locoregionally advanced NPC during IMRT era.

Detailed description

Patients with with previously untreated non-metastatic newly histologically-confirmed non-keratinizing III-IVb NPC (UICC/AJCC 7th edition) are randomly assigned to receive induction chemotherapy followed by IMRT alone (investigational group) or induction chemotherapy followed by IMRT plus concurrent chemotherapy (control group). During induction chemotherapy, patients in both groups receive 60 mg/m2 docetaxel intravenously on day 1, 60 mg/m2 cisplatin intravenously on day 1, and 600 mg/m2/d fluorouracil as a continuous infusion on days 1-5; three cycles were administered at intervals of 3 weeks. During radiotherapy, patients in investigational group received IMRT alone and patients in control group received IMRT, concurrently with weekly intravenous cisplatin at 30 mg/m2 for 6-7 weeks. IMRT is given as 2.0-2.3 Gy per fraction with five daily fractions per week for 6-7 weeks, Cumulative doses were \> 66 Gy to the primary tumor and \> 50 Gy to the bilateral cervical lymph nodes and potential sites of local infiltration. The primary endpoint is failure-free survival(FFS). Secondary clinical endpoints include overall survival (OS), locoregional failure-free survival (LRFFS), distant failure-free survival (DFFS) rates and toxic effects.
