Small-molecule STING agonists are limited by rapid excretion, low bioavailability, nonspecificity, and adverse effects. Nanomedicine is presented as a delivery platform enabling tumor-targeted administration, improving therapeutic opportunities. Evidence links cGAS-STING signaling with ferroptosis, motivating nanomedicine-based strategies that couple the pathway to ferroptotic cell death.

Pharmacological activation of the cGAS-STING pathway by cGAS-STING agoniststo overcome cancer drug resistance offers substantial potential to promote antitumor immunity. However, smallmolecule STING agonists show rapid excretion, low bioavailability, non-specificity, and adverse effects, which limit their therapeutic efficacy and in vivo applications. The recent emergence of nanomedicine has profoundly revolutionized STING agonist delivery, promoting tumor-targeted delivery and offering new opportunities for tumor-specific immunotherapy. A growing body of evidence has shown that cGAS-STING interacts with ferroptosisin cancer cells. Targeting the interplay between cGAS-STING and ferroptosis using nanomedicines offers a novel cancer treatment regimen. In this review, we outline the principal components of the cGAS-STING signaling cascade and discuss its role in cancer biology. We also review the role of the interplay between cGAS-STING and ferroptosis in cancer genesis. We then focus on providing an overview of the latest findings and emerging concepts that leverage the interplay between cGAS-STING and ferroptosis by nanomedicine to kill cancers. Finally, we discuss the key limitations of the current therapeutic paradigm and possible strategies to overcome them. This article highlights some promising therapeutic avenues that leverage the interplay of cGAS-STING and ferroptosis by nanomedicine, which could be used to treat cancer.  \nKeywords Cancer, cGAS-STING, Ferroptosis, Nanomedicine  \n†Chunfei Li and Wenyan Zhao contributed equally to this work.  \n*Correspondence:  \nWenzheng Guan  \n[cmuwzguan@163.com](cmuwzguan@163.com)  \n1Department of General Surgery, Shengjing Hospital of China Medical University, Shenyang 110004, China  \n2Department of Pediatrics, Central Hospital Affiliated to Shenyang Medical College, Shenyang 110020, China  \n3Center of Reproductive Medicine, Shengjing Hospital of China Medical University, Shenyang 110004, China  \nIntroduction  \nCancer metastasis refers to the growth and colonization of cancer cells in organs distant from the organ of origin. Metastasis, which characterizes a malignant tumor and distinguishes it from a benign tumor, is a hallmark of cancer associated with invasiveness [1, 2]. Metastasis is the ultimate and most lethal manifestation of cancer, leading to the vast majority (90%) of cancer deaths [3–6]. Immunotherapeutic agents such as anti-programmed death-ligand 1 (PD-L1) and anti-cytotoxic T lymphocyte-associated protein 4 (CTLA-4) inhibitors have emerged as revolutionary cancer treatments [7]. However, their low response rates, resistance, and toxicity pose  \n© The Author(s) 2025.
