When treating patients with immune checkpoint inhibitors, do you routinely check markers of endocrinopathies such as TSH/ACTH, or only when a patient has symptoms?

How do you monitor thyroid function for patients on immune checkpoint inhibitors?

• Thyroid function studies at baseline and before every cycle
• Thyroid function studies at baseline and every other cycle
• Thyroid function studies at baseline and q 3 mos
• Thyroid function studies at baseline and then as prompted by new symptoms
• I don't routinely monitor thyroid function studies in patients without pre-existing history
• Other
