Sequential and Concurrent Chemoradiation: State of the Art

Abstract

Most patients diagnosed with head and neck cancer have locally advanced disease. Sequential and concurrent chemoradiation are standard, nonsurgical, curative-intent treatment options. Controversy remains regarding the superiority of one approach to another. Definitive management strategies are evolving with increasing efforts to pursue deintensification of therapy for low-risk patients, and to pursue therapeutic intensification for high-risk patients. Both sequential therapy and concurrent chemoradiation play important roles in shaping treatment paradigms because both approaches may be used to investigate deintensification or intensification strategies. This article examines the latest evidence and state-of-the-art approaches, highlighting ongoing controversies and future directions.
