Background: Italy is characterized by high preva- lence of goiter. To date, only limited data about the preva- lence of goiter in the Italian adult population are available. Aim: To investigate the prevalence of thyroid ultrasound ab- normalities in adults unaware of any thyroid disease and eval- uate the rate of differentiated thyroid cancer (DTC) obtained by this intervention. Methods: Ultrasound (US) thyroid scan was performed in adult volunteers recruited by advertisement in Modena, Italy. One hundred and thirty-five women and 66 men (no.= 201), unaware of any thyroid disease (mean age of 46±10.7 yr) underwent their first thyroid US scan. Results: US thyroid abnormalities were found in 101 subjects (50.3%): 91 nodular goiters (45.2%) and 13 US-thyroiditis (6.5%) associ- ated with positive auto-antibodies in 11 of them. Seventeen subjects (18%) with nodules underwent US-fine needle aspiration biopsy with the following cytological class (C) outcome: 14 patients C2 (82%), 1 patient C3 (6%), 2 patients had C4 (12%), the latter received histological confirmation. Conclu- sions: The prevalence of thyroid abnormalities is very high in subjects unaware of any thyroid disease. DTC was found in 1% of subjects and in 2% of those affected by nodular goi- ter. Compared to the detection rate of the well-established screening programs for breast (0.45%) and colorectal (0.27%) cancer, the prevalence of DTC seems to be much higher. Thy- roid US screening could allow the detection of DTC in asymp- tomatic subjects and this diagnosis often includes DTC at an advanced stage. Thus, US screening not necessarily results in the over-diagnosis of clinically not relevant thyroid diseases.
