Protocols for the preoperative selection of palpable thyroid nodules: review and progress.
Modern protocols for the management of patients with palpable thyroid nodules agree that fine-needle aspiration is the first examination to be performed. However, they differ very much in the role attributed to scintigraphy and ultrasound examinations. In some protocols, these two techniques are not considered, whereas in others they are recommended at the end of the diagnostic workup to select for surgery those nodules with nondiagnostic or suspect fine-needle aspiration biopsy results. We report original data and literature showing that such use of scintigraphy and ultrasonography is not cost effective. Furthermore, we report original data showing that large-needle aspiration biopsy can be used to select for surgery those nodules with nondiagnostic or suspect results after fine-needle aspiration. Consequently, we suggest a new protocol for the preoperative selection of palpable thyroid nodules.
