Translating ferroptosis into oncology: challenges, opportunities and future directions

Abstract

Ferroptosis is an oxidative, lipid peroxidation-driven form of regulated cell death that occurs when antioxidant and organelle-protective systems are compromised. Increasing evidence implicates ferroptosis as a process that can exert both tumour-suppressive and tumour-promoting effects depending on cellular context at multiple stages of cancer evolution (from tumour initiation to metastatic colonization), sparking substantial interest in therapeutically exploiting this mechanism of cell death. Yet, despite rapid preclinical progress, clinical translation of ferroptosis-based strategies remains nascent. In this Review, we examine the major barriers to translation, including pharmacological limitations, tumour-intrinsic heterogeneity, microenvironmental and immune constraints, and gaps in current preclinical modelling. We also highlight emerging opportunities such as new ferroptosis-inducing agents, biomarker-guided patient selection and rational combinations with chemotherapy, radiotherapy, targeted agents or immunotherapies. Finally, we outline a translational roadmap for integrating ferroptosis-based therapies into oncology practice. By defining key challenges and future directions, this Review aims to position ferroptosis as a viable therapeutic paradigm and to accelerate progress towards clinical application. Despite substantial interest in exploiting ferroptosis — an iron-mediated, lipid peroxidation-driven form of cell death — for cancer therapy, progress towards clinical translation has been limited. This comprehensive Review describes the major barriers that have restricted ferroptosis-based therapeutic development as well as emerging opportunities presented by new ferroptosis-inducing agents, biomarker-guided patient selection and rational combination treatments.
