TERT and neoplasm: Similar results to those discussed above were obtained for the disease-free survival parameter; that is, TERT upregulation was significantly associated with shorter disease-free survival (p = 0.006), and in the subgroup analysis, the highest predictive value was also achieved with the analysis of immunohistochemical overexpression of TERT in tumor tissue (p = 0.001, HR = 4.03).
