4 Cycles Of Neoadjuvant Chemotherapy Plus Concurrent Chemoradiation Versus Concurrent Chemoradiation Alone In Patients With Stage N2-3 Nasopharyngeal Carcinoma: a Phase 3 Multicenter Randomised Controlled Trial

The standard treatment strategy of locally advanced nasopharyngeal carcinoma (NPC) nowadays is concurrent chemoradiation (CCRT) based on intensity-modulated radiation therapy (IMRT). However, distant metastasis remains the major cause of treatment failure, especially in patients with T1-4N2-3M0 diseases (N2-3 NPC). The investigators inferred that it was more appropriate to consider N2-3 NPC as a systemic disease instead of a local disease. NACT of sufficient intensity such as 4 cycles might be effective enough for control of the pre-existing micrometastases. Therefore, the objective of this phase 3 multicenter randomized controlled trial is to make a comparison between NACT of 4 cycles plus CCRT based on IMRT and CCRT alone in N2-3 NPC on distant metastasis, survival and adverse reaction.
