Objectives
Narrative objectives1	Recently, immune-checkpoint inhibitor (ICI) has been used for treatment of malignant tumors, and PD1 antibody, a representative ICI, is prescribed for non small cell lung cancer or urothelial cancer. ICI is effective even in the advanced cancer, however, it's known immune-related adverse events (irAE) including ACTH deficiency could happen. ACTH (adrenocorticotropic hormone) is secreted in anterior pituitary, and ACTH deficiency could cause adrenal failure (anorexia, body weight loss, hypotension, coma, shock, etc). Generally, the frequency of ACTH deficiency due to PD1-Ab is 1%. HLA (human leukocyte antigen) is known as essential factors to distinguish self and not-self, and it's possible HLA haplotype is associated with PD1-Ab induced ACTH deficiency. In this study, we are going to investigate susceptible HLA genotype in patients with PD1-Ab induced ACTH deficiency, and we could clarify the pathological mechanism for preventing ACTH deficiency in the future.

Other
Other related information	If specific HLA genotype are clarified in ACTH deficiency patients due to PD1-Ab treatment, it's useful to understand the pathogenic mechanisms in PD1-induced ACTH deficiency. We collect all the patients in line with criteria for selection who are treated in our hospital from May 2020 to March 2023.
