Abstract

Context: Immune checkpoint blockade is associated with endocrine-related adverse events.Thyroid dysfunction during pembrolizumab therapy, an anti-programmed cell death 1 (PD-1) receptor monoclonal antibody, remains to be fully characterized.Objective: To assess the incidence and characteristics of pembrolizumab-associated thyroid dysfunction.Design and Setting: Thyroid function was monitored prospectively in melanoma patients who initiated pembrolizumab within an expanded access program at a referral oncology center.18 Fluorodeoxyglucose uptake on positron emission tomography/computed tomography ( 18 FDG-PET/CT) was reviewed in cases compatible with inflammatory thyroiditis.Patients: Ninety-nine patients with advanced melanoma (age, 26.3-93.6 years; 63.6% females) who received at least one administration of pembrolizumab.Main Outcome Measures: Patient characteristics, thyroid function (TSH, free T 4 ), thyroid autoantibodies, and 18 FDG-PET/CT.Results: Eighteen adverse events of thyroid dysfunction were observed in 17 patients.Thyrotoxicosis occurred in 12 patients, of which nine evolved to hypothyroidism.Isolated hypothyroidism was present in six patients.Levothyroxine therapy was required in 10 of 15 hypothyroid patients.Thyroid autoantibodies were elevated during thyroid dysfunction in four of 10 cases.Diffuse increased 18 FDG uptake by the thyroid gland was observed in all seven thyrotoxic patients who progressed to hypothyroidism.Conclusions: Thyroid dysfunction is common in melanoma patients treated with pembrolizumab.Hypothyroidism and thyrotoxicosis related to inflammatory thyroiditis are the most frequent presentations.Serial measurements of thyroid function tests are indicated during anti-PD-1 monoclonal antibody therapy.Thyrotoxicosis compatible with inflammatory thyroiditis was associated with diffuse increased 18 FDG uptake by the thyroid gland.The prospective role of thyroid autoantibodies should be further investigated, together with the histopathological correlates.(

  • In the literature, only nine cases of ICPi-induced Graves' hyperthyroidism and seven cases of induced Graves' orbitopathy have been described, associated with anti-PD-1 or anti-CTLA-4 treatment or their combination, with only one patient presenting both thyrotoxicosis and orbitopathy.

    “To the best of our knowledge at the time of writing, only nine cases of ICPi-induced Graves’ hyperthyroidism and seven cases of induced Graves’ orbitopathy have been described in the literature, associated with anti-PD-1 or anti-CTLA-4 treatment or their combination (Table 3), with only one patient presenting with both thyrotoxicosis and orbitopathy [19,29,30,31,35,36,37,38,39,40,41,42,43,44].”

  • ICPi-induced thyrotoxicosis is generally due to destructive thyroiditis, with a first stage of hyperthyroidism which then resolves or evolves into secondary hypothyroidism in 50-80% of cases.

    “ICPi-induced thyrotoxicosis is generally due to destructive thyroiditis, with a first stage of hyperthyroidism which then resolves or evolves into secondary hypothyroidism (50–80%) [17,18,19].”

    From Graves’ Disease during Immune Checkpoint Inhibitor Therapy (A Case Series and Literature Review) (2021) · cites this paper as [19]

    The Results (Thyroid-related AEs; page unavailable) report that 9 of 12 patients with thyrotoxicosis progressed to hypothyroidism—75%, within the claimed range—while the other three had isolated thyrotoxicosis. The Discussion describes inflammatory thyroiditis as suspected and destructive thyroiditis as a hypothesis, not an established cause. The findings concern melanoma patients receiving pembrolizumab, rather than immune checkpoint inhibitors generally. (LLM, conf=0.87)

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.
