Many studies demonstrated that somatic BRAF gene mutation analysis increases diagnostic accuracy for papillary thyroid carcinoma (PTC), even from very small samples. The gold standard for point mutations research is direct sequencing, that implies DNA extraction, PCR with specific primers, sequencing reaction and run on an automatic sequencer. This is an expensive and time consuming method, and the possible contamination with wild-type DNA not coming from the nodule significan...

Papillary thyroid cancer (PTC) represents the majority of differentiated thyroid cancers, presenting in 29–83% of cases the activating BRAF V600E mutation. The aim of our study was to analyse the influence of BRAF V600E mutation analysis on diagnostic accuracy of fine needle aspiration biopsies (FNAB) in clinically unsuspected thyroid nodules. We therefore enrolled 496 patients (383 females, 113 males; mean age 52 years), for a total of 671 samples. FNAB were evaluated by...

Nonfunctioning adenomas (NFA) are 30% of all pituitary adenomas. Transphenoidal surgery is the first line therapy, but recurrences are frequent (12% al 69%). NFA treatment and follow-up are controversial. Aim of our study was to evaluate the recurrence prevalence and the factors associated with tumor aggressiveness in patients with NFA. We studied 30 patients that underwent surgery: 14 patients (group A, 7F, 3.92±12.48 years) with and 16 patients (group B, 6F, 56.5±1...
