In the univariate analysis of DTC patients, age (p < 0.001), TERT mutation status (p < 0.001), histological type (p = 0.004), ETE (p < 0.001), distant metastasis (p < 0.001), stage at diagnosis (p < 0.001), and tumor size (p = 0.014) were significant predictors. This evidence concerns the gene TERT and neoplasm.
