FIG. 1.

ACTH (250 μg) stimulation test of all 13 patients treated with lenvatinib at baseline (0, before starting therapy) and during follow-up (3, 6, 9, 12, 15, 18, 21, 24, and 27 months). Seven patients (#4, #6, #8, #9, #10, #11, and #12) had an insufficient response (cortisol peak <500 nmol/L) indicating adrenal insufficiency. After 12 months of treatment, PAI patient #6 interrupted lenvatinib for 34 days and ACTH stimulation was normal; after lenvatinib restarted, a recurrence of PAI (cortisol peak <500) was demonstrated (see Results). ACTH, adrenocorticotropic hormone; PAI, primary adrenal insufficiency. Color images are available online.
