Thyroid nodules are common; fine-needle aspirations commonly are read as indeterminate, necessitating surgery to exclude carcinoma. We developed a 6-gene array-based predictor model to diagnose benign versus malignant thyroid lesions. In this study, we verified whether quantitative reverse transcription-polymerase chain reaction (qRT-PCR) using this model reliably can differentiate benign from malignant thyroid nodules. ⋯ Molecular diagnosis with our 6-gene model can differentiate between benign and malignant thyroid tumors with high sensitivity and specificity. In combination, these genetic markers may be a reliable test to preoperatively diagnose the malignant potential of thyroid nodules.

The role of central neck dissection (CND) in differentiated thyroid cancer remains controversial. This study aims at elucidating the potential benefits and drawbacks of CND associated to total thyroidectomy in papillary cancer. ⋯ CND prevents central neck recurrences. Morbidity of bilateral CND is significant, and its systematic implementation in the absence on gross nodal involvement requires reassessment.
