Papillary thyroid carcinoma (PTC) has two major types, classic (PTCC) and follicular variant (FVPTC), which correlate with molecular findings and have varying clinical implications. We assessed the cytologic findings and subsequent surgical pathology findings with the molecular mutations in these two groups, including microcarcinomas. Fourty-four patients with PTC resections over a one-year period were retrospectively examined in conjunction with previous cytologic diagnoses. BRAF, NRAS and TERT promoter mutations for the resected specimens were analyzed. Correlation with previous cytology in regard to molecular mutations and tumor size (microcarcinoma) were made. Significantly more BRAF V600E mutations were seen with PTCC, whereas significantly more NRAS mutations were seen with FVPTC. TERT mutations were only seen with PTCC. Molecular studies for thyroid carcninomas are becoming increasingly more common and influence treatment and patient prognosis. BRAF and or TERT mutations are associated with a worse prognosis. NRAS mutations associated with FVPTC and may lead to milder cytologic changes compared to the BRAF- and TERT-driven PTCC.

In papillary thyroid cancer TERT promoter mutations have a worst impact on outcome than BRAF mutations

ObjectiveTranscriptional activating mutations in the promoter of the telomerase reverse transcriptase (TERT) gene were reported at high frequency in aggressive poorly differentiated and anaplastic thyroid cancers. By contrast, the relevance of these mutations in the metastatic behavior of well-differentiated thyroid cancer is still to be defined. The aim of this work was to investigate the frequency ofTERTpromoter mutations in a remarkable cohort of well-differentiated papillary thyroid carcinoma that developed distant metastases (DM-PTCs) and to establish whether these mutations may be predictive of metastatic behavior.DesignWe analyzed the frequency ofTERTpromoter mutations in a group of 43 highly aggressive DM-PTCs. As controls, we analyzed these mutations in a group of 78 PTCs without distant metastases (control-PTCs). The possible correlation betweenTERTpromoter mutations and BRAF V600E mutation was also investigated.MethodsTERTpromoter mutational status was evaluated by direct sequencing of the hotspot harboring the C228T and the C250T mutations.ResultsIn the overall cohort of 121 PTCs analyzed, 17% of cases (21/121) carried a mutation in theTERTpromoter. Noticeably, 33% of DM-PTCs were mutated in theTERTpromoter while only 9% of the control-PTCs showed a mutation in this locus. We also observed a positive association between BRAF V600E andTERTC228T mutations in the cohort of DM-PTCs.ConclusionsThese results indicate thatTERTpromoter mutations are associated with the development of distant metastases in PTCs and may help in predicting aggressive behavior in this type of tumor.
