Malignancy rate in thyroid nodules classified as Bethesda category III (AUS/FLUS).

Background: The Bethesda System for Reporting Thyroid Cytopathology is the standard for interpreting fine needle aspiration (FNA) specimens. The "atypia of undetermined significance/follicular lesion of undetermined significance" (AUS/FLUS) category, known as Bethesda Category III, has been ascribed a malignancy risk of 5-15%, but the probability of malignancy in AUS/FLUS specimens remains unclear. Our objective was to determine the risk of malignancy in thyroid FNAs categorized as AUS/FLUS at a comprehensive cancer center.

Establishing a training program for residents in robotic surgery.

Objectives/hypothesis: To develop a program for teaching robotic skills to residents. To assess the development of proficiency in basic robotic surgical skills in a resident cohort.

Study Design: Prospective educational project using a commercially available surgical robot.
