Abstract

OBJECTIVE: Sunitinib is a novel tyrosine kinase inhibitor with antitumor and antiangiogenic effects. An observed higher than expected rate of hypothyroidism in sunitinib-treated patients prompted assessment of the incidence of hypothyroidism. DESIGN: Patients taking sunitinib had their thyroid function tests (TFTs) assessed via chart review. To explore potential effects on the thyroid, we examined the antiperoxidase activity of sunitinib by in vitro testing its effect on guaiacol oxidation and protein iodination by lactoperoxidase. MAIN OUTCOME: Of the 89 patients who took sunitinib, 49 patients were excluded from analysis for several reasons. Of the remaining 40 patients, 21 (53%, 24% of the original 89) developed elevated thyrotropin (TSH) after a median of 5 months (range 1-36 months). Median TSH was 21.4 mU/L (range 4.6-174 mU/L). In vitro, sunitinib had antiperoxidase activity that was about one-fourth the potency of propylthiouracil. CONCLUSIONS: Of the 40 patients who had TFTs assessed after starting sunitinib, 53% developed elevated TSH. We recommend that all patients treated with sunitinib be monitored for hypothyroidism. The mechanism of the antithyroid effect appears to be inhibition of peroxidase activity. Further research is needed to confirm the mechanism by which sunitinib induces hypothyroidism.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
