Care was provided by endocrinologists and evaluated for consistency with the Japan Endocrine Society (JES) guidelines. Thyroid dysfunction (64.3%) and adrenal insufficiency (42.9%) were the most frequent irAEs, followed by hypophysitis and insulin\u2010dependent diabetes mellitus (each 8.3%). Management generally conformed to JES recommendations, including levothyroxine and hydrocortisone replacement at guideline\u2010recommended doses. More than 80% of patients received maintenance therapy as recommended in the JES guidelines. In some cases, higher hydrocortisone doses were administered based on clinical judgment, particularly in patients with malignancy\u2010related poor general condition. No hospitalizations occurred for thyroid dysfunction, whereas four patients were admitted for adrenal insufficiency\u2010related sick day management. For the treatment of hypophysitis, continuous hydrocortisone replacement therapy was commonly administered. All cases of ICI\u2010induced diabetes presented with severe hyperglycemia, highlighting the importance of early recognition. Survival analysis indicated a trend toward improved prognosis in patients with renal cell carcinoma who developed endocrine irAEs. Notably, the occurrence of endocrine irAE did not directly necessitate switching or discontinuation of ICI therapy. Although limited by its single\u2010center design and the possibility of underreporting, this study provides valuable clinical insights into endocrine irAE management and supports the feasibility of JES guidelines. These findings underscore the importance of specialized endocrine care and guideline\u2010based management in optimizing safety and long\u2010term outcomes in ICI\u2010treated cancer patients, particularly in settings with limited endocrinology resources.<\/jats:p>","DOI":"10.1002\/cam4.71818","type":"journal-article","created":{"date-parts":[[2026,4,13]],"date-time":"2026-04-13T05:19:28Z","timestamp":1776057568000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Endocrinologist\u2010Led Management of Endocrine Immune\u2010Related Adverse Events: Real\u2010World Evidence Supporting the Japan Endocrine Society Guidelines"],"prefix":"10.1002","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0471-5164","authenticated-orcid":false,"given":"Kota","family":"Nishihama","sequence":"first","affiliation":[{"name":"Department of Diabetes, Metabolism and Endocrinology Mie University Graduate School of Medicine  Tsu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hajime","family":"Fujimoto","sequence":"additional","affiliation":[{"name":"Department of Pulmonary and Critical Care Medicine Mie University Graduate School of Medicine  Tsu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7420-563X","authenticated-orcid":false,"given":"Kanako","family":"Saito","sequence":"additional","affiliation":[{"name":"Department of Medical Oncology Mie University Hospital  Tsu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chisa","family":"Inoue","sequence":"additional","affiliation":[{"name":"Department of Diabetes, Metabolism and Endocrinology Mie University Graduate School of Medicine  Tsu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuko","family":"Okano","sequence":"additional","affiliation":[{"name":"Department of Diabetes, Metabolism and Endocrinology Mie University Graduate School of Medicine  Tsu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Atsuro","family":"Takeshita","sequence":"additional","affiliation":[{"name":"Department of Diabetes, Metabolism and Endocrinology Mie University Graduate School of Medicine  Tsu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mei","family":"Uemura","sequence":"additional","affiliation":[{"name":"Department of Diabetes, Metabolism and Endocrinology Mie University Graduate School of Medicine  Tsu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Corina N.","family":"D'Alessandro\u2010Gabazza","sequence":"additional","affiliation":[{"name":"Department of Immunology Mie University Graduate School of Medicine  Tsu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Esteban C.","family":"Gabazza","sequence":"additional","affiliation":[{"name":"Department of Immunology Mie University Graduate School of Medicine  Tsu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yutaka","family":"Yano","sequence":"additional","affiliation":[{"name":"Department of Diabetes, Metabolism and Endocrinology Mie University Graduate School of Medicine  Tsu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Taro","family":"Yasuma","sequence":"additional","affiliation":[{"name":"Department of Diabetes, Metabolism and Endocrinology Mie University Graduate School of Medicine  Tsu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,4,12]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.3803\/EnM.2021.1007"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1507\/endocrj.EJ19\u20100163"},{"key":"e_1_2_11_4_1","unstructured":"N.
