The present narrative review collected literature from the PubMed, Web of Science, Embase, CNKI, and Wanfang databases between 2016 and 2026, and hence discussed the molecular mechanisms by which CRP flavonoids reshape the lung cancer TME, namely their regulation of oxidative stress-inflammation homeostasis, correction of lipid metabolic reprogramming, induction of pyroptosis, and inhibition of epithelial-mesenchymal transition. Here, CRP is linked to lung cancer.
