Results of a prospective thyroid ultrasound screening program in adenomatous polyposis patients.

Background: Patients with adenomatous polyposis may be at increased risk for developing thyroid cancer (TC). However, screening guidelines for TC in these patients are not well established.

Methods: Patients with a diagnosis of familial adenomatous polyposis, attenuated familial adenomatous polyposis, and gene mutation-negative adenomatous polyposis enrolled in our Hereditary Colorectal Cancer Family Registry were eligible for a screening thyroid ultrasound (US).
