TERT and neoplasm: When assessing differences between TERT-promoter-mutated and wild-type FT-UMPs, a statistically significant association was seen between the presence of a TERT promoter mutation and the occurrence of distant metastasis (p = 0.003; Table 3), higher age at surgery (both for continuous and ≥55 years, p = 0.016 and p = 0.019 respectively; Table 3), larger tumor size (p = 0.045, Table 3), and equivocal vascular invasion (p = 0.042; Table 3).
