Nivolumab, an anti-programmed cell death-1 monoclonal antibody, is currently used to treat many types of advanced cancers including recurrent and metastatic head and neck cancer. However, there are increasing reports concerning immune-related adverse events related to nivolumab therapy. Here, we report three patients who presented with adrenal insufficiency following nivolumab therapy. Two were diagnosed as having isolated adrenocorticotropic hormone (ACTH) deficiency and one was diagnosed as having primary adrenal insufficiency. All three patients complained of progressive fatigue and appetite loss, so we measured their blood cortisol and ACTH levels and diagnosed them as having adrenal deficiency. Treatment with nivolumab was discontinued for all three patients, and replacement therapy using hydrocortisone was successful after a few days in all cases. Two patients subsequently resumed nivolumab therapy because their general condition had improved. Complaints of fatigue and appetite loss during cancer treatment are common and tend to be regarded as unimportant. Although adrenal insufficiency due to nivolumab is relatively rare, complaints of these symptoms could lead to the detection of adrenal insufficiency at an early stage. The present report highlights the importance of the early recognition of adrenal insufficiency.

Nivolumab exerts antitumor effects by inhibiting binding of PD-L1 to PD-1, and offers proven effectiveness in various disease areas, including cancers of the head and neck. The mechanisms of action lead nivolumab to induce immune-related adverse events (irAE). We report a case of pituitary-adrenal dysfunction to isolated adrenocorticotropic hormone (ACTH) deficiency as an irAE of nivolumab in a patient treated for head and neck cancer. This is the first report of an irAE of nivolumab in the field of head and neck squamous cell cancer. The patient was a man in his 50s with cancer of the tongue and hypopharynx that recurred after chemoradiotherapy, surgery and chemotherapy. After starting nivolumab, irAEs developed after 8 courses. The case was managed from the early stages in collaboration with the endocrinology department. Pituitary-adrenal hypofunction due to isolated ACTH deficiency was diagnosed on the basis of endocrine tests. The patient responded to hydrocortisone replacement therapy and has been able to continue treatment with nivolumab while continuing oral hydrocortisone. Although irAEs involving pituitary gland disorders are rare, these events can become life-threatening when severe. Early diagnosis and treatment are essential and require regular blood sampling and collaboration with specialists from an early stage.
