1 TERT Promoter Mutation Predicts Radioiodine-Refractory Character in Distant Metastatic Differentiated Thyroid Cancer. Iodine-131 telomerase reverse transcriptase Homo sapiens
2 TERT mutation closely correlated with a poor response to radioiodine therapy (P < 0.001), and all 15 patients were classified as refractory to radioiodine therapy, with a positive predictive value of 100% at the endpoint of follow-up. Iodine-131 telomerase reverse transcriptase Homo sapiens
3 TERT mutation was associated with older mean age at diagnosis (P < 0.001), larger mean tumor diameter (P = 0.013), and greater likelihood of both BRAF mutation coexistence (P = 0.044) and radioiodine-refractory character (P < 0.001). Iodine-131 telomerase reverse transcriptase Homo sapiens
4 In the 36 cases whose imaging results underwent semiquantitative analysis, TERT mutation significantly correlated with non-radioiodine avidity, with a much lower mean tumor-to-background ratio (obtained from postradioiodine whole-body scanning) than in TERT wild-type cases (P < 0.001). Iodine-131 telomerase reverse transcriptase Homo sapiens
5 In addition, patients with distant metastatic DTC with TERT mutation were more likely to lose radioiodine avidity at the initial radioiodine therapy than were those with only BRAF mutation (8/8 vs. 5/11; Fisher exact test, P = 0.018). Iodine-131 telomerase reverse transcriptase Homo sapiens
6 In addition, patients with distant metastatic DTC with TERT mutation were more likely to lose radioiodine avidity at the initial radioiodine therapy than were those with only BRAF mutation (8/8 vs. 5/11; Fisher exact test, P = 0.018). Iodine-131 telomerase reverse transcriptase Homo sapiens
7 CONCLUSION: TERT mutation closely associates with non-radioiodine avidity in distant metastatic DTC, and when compared with BRAF mutation, TERT mutation manifested a greater negative influence on radioiodine uptake. Iodine-131 telomerase reverse transcriptase Homo sapiens
8 CONCLUSION: TERT mutation closely associates with non-radioiodine avidity in distant metastatic DTC, and when compared with BRAF mutation, TERT mutation manifested a greater negative influence on radioiodine uptake. Iodine-131 telomerase reverse transcriptase Homo sapiens
9 TERT mutation could also be used as an early predictor of radioiodine-refractory cases. Iodine-131 telomerase reverse transcriptase Homo sapiens
