Research progress of ferroptosis in cervical cancer treatment

Objective: Ferroptosis, an iron-dependent form of regulated cell death driven by lipid peroxidation, has recently emerged as a promising therapeutic strategy for cervical cancer, particularly in tumors resistant to conventional radiotherapy and chemotherapy. This review aims to systematically summarize the current understanding of ferroptosis mechanisms in cervical cancer and its potential therapeutic implications.Methods: We comprehensively reviewed the literature focusing on key regulators of ferroptosis in cervical cancer, including system Xc- (SLC7A11), glutathione peroxidase 4 (GPX4), iron metabolism, and lipid peroxidation pathways. The interactions between ferroptotic processes and cervical cancer-specific cellular redox homeostasis and metabolic adaptations were analyzed. Additionally, the crosstalk between ferroptosis and oncogenic signaling pathways such as p53 and NRF2 was examined.Results: Accumulating preclinical evidence indicates that induction of ferroptosis sensitizes resistant cervical cancer cells to standard therapies by disrupting cellular redox balance and metabolic mechanisms. The intricate interplay between ferroptotic pathways and established tumorigenic signaling networks highlights the complexity of ferroptosis regulation in cervical cancer progression. Nonetheless, translational challenges remain, including the lack of robust ferroptosis-specific biomarkers for clinical application, potential off-target toxicity, and the need for optimized combination regimens.Conclusion: Future research should prioritize elucidating ferroptosis modulators within the tumor microenvironment, refining combinatorial therapeutic strategies, and developing targeted delivery systems. Integrating ferroptosis-based approaches with existing treatments holds significant potential to overcome therapeutic resistance and improve outcomes in advanced or recurrent cervical cancer. This review provides new insights and strategic directions for leveraging ferroptosis as a novel and actionable vulnerability in cervical cancer therapy.
