Abstract:
Objective To investigate the prevalence of BRAF V600E mutation in thyroid nodules and to analyze the relationship between BRAF V600E mutation and various clinicopathological features. Methods BRAF V600E mutant gene test was done in 463 cases of thyroid nodules collected from April 2015 to July 2018 in Beijing Hospital. Pathologic sections of 444 cases of papillary thyroid carcinoma were reviewed and clinical information was collected.Statistical analysis of the relationship between BRAF V600E gene mutation and various clinicopathological features was performed with SPSS 21.0 statistical software. Results There were 109 males and 354 females in the cohort, with a male to female ratio of 1.0∶3.2. The patient ranged in age from 16 to 82 years, with an average age of 46.1 years. The BRAF V600E mutation rates in papillary thyroid carcinoma, benign thyroid nodules and other thyroid carcinoma were 86.5%(384/444),0/15 and 1/4,respectively.There was significant correlation between BRAF V600E mutation and histological diagnosis of papillary thyroid carcinoma(P<0.05). There was no correlation with age, gender, multifocality, bilaterality, coexisting lymphocytic thyroiditis, nodular goiter, maximum diameter, capsule invasion, extrathyroidal extension and clinical stage (P>0.05). Conclusions BRAF V600E gene mutation is closely related to the occurrence of papillary thyroid carcinoma. BRAF V600E has significant value in the diagnosis of papillary thyroid carcinoma. While BRAF V600E mutation is related to the histological diagnosis, it shows no correlation with other clinicopathologic features. BRAF V600E mutation is not an independent prognostic factor in papillary thyroid carcinoma patients.
