Abstract
Locally advanced nasopharyngeal carcinoma (NPC) is still associated with significant locoregional failure and poor overall survival (OS) after chemoradiation. The maximal therapeutic effect of conventional chemotherapy combined with radiation may have been reached and there is a clinical need to identify additional adverse prognostic factors that could be targeted therapeutically. Hypoxia, a known prognostic factor in head and neck cancers is an attractive target in NPC with various treatment strategies available such as hypoxic cell sensitisers/cytotoxins and increasing intratumoral oxygen delivery, to overcome the poorer outcomes associated with this phenotype. Thus, we aim to review the clinical significance of hypoxia as well as the current and future of molecular hypoxia imaging in NPC.
