Elevated cfDNA correlated strongly with metastasis and adverse pathological features, outperforming CA15-3 in predicting metastasis (AUC = 0.962–0.987). High cfDNA concentrations associated with poorer disease-free and overall survival (p<0.001).

A growing body of evidence implicates dysregulated m6A regulators in TC pathogenesis; yet the multiplicity of effectors and their context-dependent actions complicate mechanistic resolution. This review synthesizes current advances, delineating m6A’s involvement in four cardinal arenas of thyroid tumorigenesis: altered cellular behaviors (proliferation, migration), metabolic reprogramming, programmed cell death (apoptosis and ferroptosis), and resistance to targeted, radioactive iodine, and immunotherapeutic strategies. We further examine the emerging interface between m6A and non-coding RNAs, highlighting how this axis rewires oncogenic networks.
