Two therapeutic strategies show promising potential to counter this challenge: adjunct therapies that target hypoxia-related signaling and metabolic pathways, including HIF inhibitors, HDAC inhibitors, natural compounds, and metabolic modulators, and oxygenation approaches designed to reverse hypoxic stress. Notably, advances in nanotechnology-based oxygen-delivery systems provide sustained, localized reoxygenation of hypoxic regions, addressing limitations of conventional oxygen therapies. Although these interventions demonstrate strong preclinical efficacy, translation to consistent clinical benefit remains limited, partly due to inadequate hypoxia biomarkers and insufficient preclinical models that fail to replicate tumor oxygen gradients.
