CQ15. What Is the Likelihood That Multinodular Goiter Will Be Surgically Resected After Observation?

Multinodular goiter is a frequently seen thyroid disease, but it is usually a hyperplastic lesion that is called adenomatous goiter, indicating that, in principle, surgery is not necessary unless clinical manifestations become clearly apparent. However, in practice, these nodules are often difficult to distinguish from follicular tumor and papillary carcinoma occasionally coexists. FNA is performed for the largest nodule or nodules suspected of malignancy in many specialist hospitals, and observation continues when the results are negative. Thus, this CQ investigates the possibility of surgical resection for multinodular goiter after observation.
