Prognostic value of postsurgical stimulated thyroglobulin levels after initial radioactive iodine therapy in well‐differentiated thyroid carcinoma

BACKGROUND: In well-differentiated thyroid carcinoma, predictors of future positivity of stimulated thyroglobulin (>2 microg/L) after initial radioactive iodine treatment are not known. METHODS: In a retrospective study, we used logistic regression analysis to determine whether postoperative stimulated thyroglobulin measurements and pathologic stage independently predict future stimulated thyroglobulin positivity.
