We also tested another TERT mutation, TERT C250 T, although this was not detected in PPTC patients. In this study, 48 patients with PPTC(41 with classic PPTC) were enrolled. DNA was extracted from PPTC tissues and TERT C228 T mutation analysis was performed. Chi-squared analysis,Fisher’s exact test, and a t-test were applied to test the significance of differences. The TERT C228 T mutation presented in 13(27.1%) of the 48 PPTC patients and 10(24.4%) of the 41 classical PPTC patients. There were significant differences between PPTC patients with the TERT C228 T mutation and those without in terms of modified radical neck dissection, multifocality,capsular invasion, extrathyroidal invasion, and American Joint Committee on Cancer(AJCC) tumor stage(P<0.05). In classical PPTC, there were additional significant differences in other clinic-pathological features, such as AJCC nodal stage(P=0.009)and American Thyroid Association(ATA) PPTC stage(P=0.021) between patients with and without the TERT C228 T mutation.These findings indicate that the TERT C228 T mutation is significantly correlated with certain aggressive clinic-pathological features of PPTC.展开更多
