Metastatic involvement of the pituitary gland in lung cancer (LC) typically indicates advanced disease and is associated with poor prognosis and pituitary insufficiency, which often remains underdiagnosed and significantly affects quality of life and survival. We present four cases of pituitary metastasis (PM) originating from LC, characterized by distinct histological subtypes, variable timing from initial diagnosis, and diverse clinical manifestations. Clinical presentation was heterogeneous: two patients had involvement of both pituitary lobes with multiple pituitary hormone deficiencies, one had anterior lobe involvement with anterior pituitary deficiency following immune checkpoint inhibitor-associated hypophysitis, and one remained asymptomatic. Therapeutic approaches included partial surgical resection followed by radiotherapy in two patients and radiotherapy alone in the other two; all patients continued systemic antineoplastic therapy and received hormone replacement as indicated. Mean overall survival was 7.5 months. PM can occur across all histological subtypes of LC and typically signifies advanced disease with poor prognosis. Early identification and appropriate management of hypopituitarism may improve quality of life and clinical outcomes.<\/jats:p>","DOI":"10.3390\/curroncol33060362","type":"journal-article","created":{"date-parts":[[2026,6,17]],"date-time":"2026-06-17T01:58:38Z","timestamp":1781661518000},"page":"362","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Pituitary Metastasis in Lung Cancer Patients: Case Series and Review of the Literature"],"prefix":"10.3390","volume":"33","author":[{"given":"Sofia","family":"Ntouraki","sequence":"first","affiliation":[{"name":"Oncology Unit, Third Department of Internal Medicine, Sotiria General Hospital for Chest Diseases, School of Medicine, National and Kapodistrian University of Athens, 11527 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9803-7789","authenticated-orcid":false,"given":"Afroditi","family":"Roumpou","sequence":"additional","affiliation":[{"name":"Endocrine Unit, Second Propaedeutic Department of Internal Medicine, Attikon University Hospital, School of Medicine, National and Kapodistrian University of Athens, 12462 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Athina","family":"Asimakopoulou","sequence":"additional","affiliation":[{"name":"Oncology Unit, Third Department of Internal Medicine, Sotiria General Hospital for Chest Diseases, School of Medicine, National and Kapodistrian University of Athens, 11527 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2902-3391","authenticated-orcid":false,"given":"Ioannis","family":"Gkiozos","sequence":"additional","affiliation":[{"name":"Oncology Unit, Third Department of Internal Medicine, Sotiria General Hospital for Chest Diseases, School of Medicine, National and Kapodistrian University of Athens, 11527 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fotini","family":"Sarropoulou","sequence":"additional","affiliation":[{"name":"Oncology Unit, Third Department of Internal Medicine, Sotiria General Hospital for Chest Diseases, School of Medicine, National and Kapodistrian University of Athens, 11527 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria","family":"Mani","sequence":"additional","affiliation":[{"name":"Oncology Unit, Third Department of Internal Medicine, Sotiria General Hospital for Chest Diseases, School of Medicine, National and Kapodistrian University of Athens, 11527 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Androniki","family":"Marioli","sequence":"additional","affiliation":[{"name":"Oncology Unit, Athens Medical Group, 15125 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dimitrios","family":"Bouklas","sequence":"additional","affiliation":[{"name":"Department of Pathology, Georgios Gennimatas General Hospital, 11527 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Konstantinos","family":"Syrigos","sequence":"additional","affiliation":[{"name":"Oncology Unit, Third Department of Internal Medicine, Sotiria General Hospital for Chest Diseases, School of Medicine, National and Kapodistrian University of Athens, 11527 Athens, Greece"},{"name":"Oncology Unit, Athens Medical Group, 15125 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melpomeni","family":"Peppa","sequence":"additional","affiliation":[{"name":"Oncology Unit, Third Department of Internal Medicine, Sotiria General Hospital for Chest Diseases, School of Medicine, National and Kapodistrian University of Athens, 11527 Athens, Greece"},{"name":"Endocrine Unit, Second Propaedeutic Department of Internal Medicine, Attikon University Hospital, School of Medicine, National and Kapodistrian University of Athens, 12462 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"805","DOI":"10.1159\/000506810","article-title":"Metastatic Spread to the Pituitary","volume":"110","author":"Shimon","year":"2020","journal-title":"Neuroendocrinology"},{"key":"ref_2","first-page":"146","article-title":"Pituitary metastasis: A clinical overview","volume":"90","author":"Henry","year":"2021","journal-title":"Ulst.
