The next decade of clinical trials in locoregionally advanced nasopharyngeal carcinoma

Abstract

Clinical trials are powerful weapons in the battle against nasopharyngeal carcinoma (NPC). Based on clinical trials conducted in the past two decades, concurrent chemoradiotherapy combined with adjuvant chemotherapy or induction chemotherapy has been recommended as the standard treatment for locoregionally advanced NPC in various guidelines. However, there remain shortcomings concerning current treatment modalities that should be refined in future research. In this article, we review the achievements of published clinical trials for locoregionally advanced NPC and propose future directions for subsequent clinical trials. We believe that refinement of current regimens of chemotherapy, de-intensification of treatment for specific groups of patients, developing personalized treatment based on predictors ( e.g. applying plasma Epstein-Barr virus DNA) and investigating novel therapies, such as targeted therapy and immunotherapy, should be applied with the highest priority when designing clinical trials for locoregionally advanced NPC in the next decade.
