BRAF mutation in the elderly submitted to thyroidectomy.

Objective: To evaluate the frequency of the BRAF V600E mutation in patients over 65 years of age undergoing thyroidectomy, correlating its presence or absence with the different histologic lesions, their variants and with prognostic factors of papillary carcinoma.

Methods: We evaluated 85 patients over 65 years of age who underwent thyroidectomy, analyzing the BRAF V600E mutation by RT-PCR performed after DNA extraction from the paraffin blocks.

Results: The study detected the presence or absence of BRAF V600E mutation in 47 patients (55.
