ABSTRACT
BACKGROUND:
The management of papillary thyroid microcarcinomas with TERT ± BRAF V600E mutations remains controversial owing to their potential associations with tumor aggressiveness. This study evaluated the clinical implications of these mutations in management of patients with papillary thyroid microcarcinomas.METHODS:
Between June 2019 and October 2020, surgical specimens from 504 consecutive patients with papillary thyroid microcarcinomas were obtained at a tertiary hospital. The mutation statuses of TERT promoter and BRAF V600E were assessed by polymerase chain reaction. The prevalence and relationships of TERT ± BRAF V600E mutations with clinical, radiological, and pathological characteristics were evaluated.RESULTS:
Of 504 patients with papillary thyroid microcarcinomas, TERT ± BRAF V600E mutations were found in 3.2% (16/504). Of these 16 patients, 93.8% (15/16) of papillary thyroid microcarcinomas with TERT promoter mutations also harbored BRAF V600E mutations. Correlation analysis showed that TERT ± BRAF V600E mutations were not associated with aggressive clinical, radiological, or pathological features (P > .05). The presence of lymph node metastasis was not associated with mutation status (P = .834).CONCLUSION:
TERT ± BRAF V600E mutations in patients with papillary thyroid microcarcinomas are not associated with any unfavorable clinicopathological features, including lymph node metastasis status.
