Introduction: It is universally accepted that calcitonin (CT), a hormone secreted by the parafollicular cells of the thyroid, is a specific, sensitive and early marker of Medullary Thyroid Carcinoma (CMT), with higher diagnostic accuracy than fine needle aspiration biopsy(FNAB).

Predictive factors for recurrent non-diagnostic fine-needle aspiration biopsy in thyroid nodules

Benido Silva Vânia , Maria Teresa Vânia , Carvalho André , Freitas Cláudia

IntroductionThe most cost-effective, minimally invasive and accurate tool to discriminate benign from malignant thyroid nodules is a fine-needle aspiration biopsy (FNAB). However, 2%–24% of FNABs provide non-diagnostic results, which are a clinical challenge, particularly when this result is recurrent.AimTo determine the predictive factors for recurrent non-diagnostic FNAB in thyroid nodules.<p class...
