Novel acquisitions in the diagnosis of medullary thyroid carcinoma.

Introduction: The correct identification of medullary thyroid carcinoma (MTC) has been a challenge since its first description. In the last few years, some advances in this context have been achieved. Here we aimed to review and discuss published data on the more recent acquisition in the diagnosis of MTC.

Galectin-3 and HBME-1 improve the accuracy of core biopsy in indeterminate thyroid nodules.

Core needle biopsy (CNB) has been recently described as an accurate second-line test in thyroid inconclusive cytology (FNA). Here we retrospectively investigated the potential improvement given by Galectin-3, Cytokeratin-19, and HBME-1 on the accuracy of CNB in thyroid nodules with prior indeterminate FNA report. The study included 74 nodules.

Ultrasound features of medullary thyroid carcinoma correlate with cancer aggressiveness: a retrospective multicenter study.

Background: Poor prognosis of medullary thyroid cancer (MTC) with suspicious ultrasound (US) features has been reported. The aim of the study was to investigate the association between preoperative US presentation and aggressiveness features of MTC. Also, US features of MTC were compared with those previously reported.

Clinical characteristics as predictors of malignancy in patients with indeterminate thyroid cytology: a meta-analysis.

Indeterminate thyroid nodules (ITN) constitute the gray zone of thyroid fine-needle aspiration cytology (FNAC). About 70-80 % of ITN are later diagnosed as benign; therefore, it is very important to identify the predictors of malignancy. Aim of the study was to summarize published data about clinical risk factors for malignancy in patients with ITN and thereby provide more robust estimates of the effect of these risk factors.
