Despite its impact, outpatient treatment models in the U.S. remain limited and unstandardized. Here, we aim to describe the structure, implementation, patient characteristics, and real-world clinical trajectories of a multidisciplinary clinic for cancer cache as well as other forms of unintentional weight loss clinic within an academic endocrinology practice. Methods: We conducted a retrospective observational cohort study of 103 patients referred to a single-center unintentional weight loss clinic over five years. Patients received comprehensive assessments (weight trajectory, nutrition status, 5\u00d7 sit-to-stand test, handgrip strength) and personalized interventions including nutrition counseling, resistance training, and pharmacologic therapies. Results: Among 103 patients (median age 69.7 years; 53% male), 64% had cancer, while 36% were referred for non-malignant causes of weight loss or cachexia. Reduced appetite or food intake was reported in 43%, and functional impairment was common, with low handgrip strength in 47% and impaired 5\u00d7 sit-to-stand performance in 79% of assessed patients. Systemic abnormalities were frequent, including elevated hs-CRP (57%), elevated neutrophil-to-lymphocyte ratio (43%), and hypoalbuminemia (26%). Among patients with available paired follow-up data, the median rate of weight change shifted from \u22120.5 kg\/month prior to enrollment to 0.0 kg\/month three months after the initial visit (p &lt; 0.0001). Five-times sit-to-stand performance improved modestly at three months (p = 0.042), while handgrip strength was unchanged. Half of patients that engaged with the clinic returned for at least follow-up, but there was no identifiable difference between the population of patients that returned versus those that did not. Conclusions: A structured, multidisciplinary unintentional weight loss clinic in an endocrinology setting was associated with stabilization of weight and modest changes in physical function in this single-center cohort among patients who engaged in follow-up. These findings highlight the successful implementation of integrated outpatient care models and provide practice-based context for future interventions and therapeutic evaluations.<\/jats:p>","DOI":"10.3390\/cancers18060946","type":"journal-article","created":{"date-parts":[[2026,3,13]],"date-time":"2026-03-13T17:36:48Z","timestamp":1773423408000},"page":"946","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Implementation and Feasibility of a Multidisciplinary Endocrine-Led Outpatient Clinic for Cancer Cachexia and Other Forms of Unintentional Weight Loss: A Real-World Observational Study"],"prefix":"10.3390","volume":"18","author":[{"given":"Anirudh","family":"Murthy","sequence":"first","affiliation":[{"name":"Department of Medicine, Weill Cornell Medicine, New York, NY 10065, USA"},{"name":"Stony Brook Medicine, Stony Brook, NY 11794, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Morgan","family":"Simons","sequence":"additional","affiliation":[{"name":"Department of Medicine, New York University (NYU) Grossman School of Medicine, 435 E. 30th Street, New York, NY 10016, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anne","family":"Jablonski","sequence":"additional","affiliation":[{"name":"Department of Medicine, Weill Cornell Medicine, New York, NY 10065, USA"},{"name":"Department of Medicine, New York University (NYU) Grossman School of Medicine, 435 E. 30th Street, New York, NY 10016, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maurice","family":"Hurd","sequence":"additional","affiliation":[{"name":"Department of Medicine, Weill Cornell Medicine, New York, NY 10065, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alpana","family":"Shukla","sequence":"additional","affiliation":[{"name":"Department of Medicine, Weill Cornell Medicine, New York, NY 10065, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0784-9248","authenticated-orcid":false,"given":"Marcus D.","family":"Goncalves","sequence":"additional","affiliation":[{"name":"Department of Medicine, Weill Cornell Medicine, New York, NY 10065, USA"},{"name":"Department of Medicine, New York University (NYU) Grossman School of Medicine, 435 E. 30th Street, New York, NY 10016, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1824","DOI":"10.1016\/j.cell.2023.03.028","article-title":"Cachexia: A systemic consequence of progressive, unresolved disease","volume":"186","author":"Ferrer","year":"2023","journal-title":"Cell"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"261","DOI":"10.1007\/s13539-014-0164-8","article-title":"Prevalence, incidence and clinical impact of cachexia: Facts and numbers\u2014Update 2014","volume":"5","author":"Anker","year":"2014","journal-title":"J.
