TERT and neoplasm: In particular, the surrounding mucosa adjacent to tumours with -124 C>T mutated TERT promoter showed the shortest telomeres (p=0.016; Figure 1B), despite these patients being younger [median (IQR), 64(58–70) years] than those with unmutated tumours [median (IQR), 67(48–74) years] or with tumours harbouring -146 C>T mutations [median (IQR), 75(71–80) years] (p for age=0.065; data not shown).
