Cervical cancer (CeCa) remains a significant global health burden, with complex interactions between oxidative stress and immune response playing critical roles in its pathogenesis and progression. This review synthesizes current knowledge on the molecular mechanisms linking oxidative stress pathways and immune evasion, particularly focusing on HPV oncogenes E6 and E7. We highlight the dual roles of immune components such as Type 17 T helper (Th17) cells and the antioxidant enzyme superoxide dismutase 2 (SOD2), which exhibit context-dependent tumor-promoting and suppressive functions. While extensive mechanistic insights have been gained, translation to clinical practice remains limited, partly due to inconsistent biomarkers and incomplete understanding of therapeutic resistance. Recent advances in targeted therapies, including mitochondrial inhibitors, Immune checkpoint inhibitors (ICIs) (e.g., pembrolizumab, nivolumab), and PARP inhibitors, demonstrate promise but face translational hurdles such as assay variability and immune-related adverse events. Future research must address gaps including predictive biomarker development, noninvasive monitoring via liquid biopsy, and rational combination therapies integrating redox modulation and immunotherapy. Enhanced multi-omics integration and refined preclinical models are essential to advance personalized treatment strategies for CeCa.
